The Whitehorse Star was a newspaper in Whitehorse , Yukon , Canada.
122-775: The newspaper was founded in 1900 about a year after the Klondike Gold Rush ended. The paper was originally called the Northern Star , by was later changed to the White Horse Star, Whitehorse Daily Star and since 2019 as the Whitehorse Star. In June 1950, Horace Moore sold the newspaper to Tom Bain, who had been editor of the Cambie News in Vancouver for 12 years. The new owner doubled
244-399: A fault . Water often lubricates faults, filling in fractures and jogs. About 10 kilometres (6.2 mi) below the surface, under very high temperatures and pressures, the water carries high concentrations of carbon dioxide, silica, and gold. During an earthquake, the fault jog suddenly opens wider. The water inside the void instantly vaporizes, flashing to steam and forcing silica, which forms
366-434: A solid solution series with the native element silver (as in electrum ), naturally alloyed with other metals like copper and palladium , and mineral inclusions such as within pyrite . Less commonly, it occurs in minerals as gold compounds, often with tellurium ( gold tellurides ). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid ), forming
488-572: A cabin. Premiums of $ 100 ($ 2,700), however, were soon paid and the steamship companies hesitated to post their rates in advance since they could increase on a daily basis. Those who landed at Skagway made their way over the White Pass before cutting across to Bennett Lake . Although the trail began gently, it progressed over several mountains with paths as narrow as 2 feet (0.61 m) and in wider parts covered with boulders and sharp rocks. Under these conditions horses died in huge numbers, giving
610-783: A cover price of $ 1.00. In early April 2024, the newspaper announced plans to publish its final edition on May 17, after efforts by co-owner and publisher Michele Pierce to develop a new business strategy to deal with years of financial difficulties blamed on the move of advertising from print to online, or to sell the paper, failed. The Star has been criticised for publishing racist depictions and opinions about minority groups. In particular Indigenous and Black people. The newspaper has been accused of promoting racist stereotypes about people of colour and targeting non-white Yukoners in its coverage. The newspaper's active online comments section has also been criticized for platforming hateful views against Indigenous people. Yukon residents have noted that
732-542: A day. From Seattle or San Francisco, prospectors could travel by sea up the coast to the ports of Alaska. The route following the coast is now referred to as the Inside Passage . It led to the ports of Dyea and Skagway plus ports of nearby trails. The sudden increase in demand encouraged a range of vessels to be pressed into service including old paddle wheelers , fishing boats, barges, and coal ships still full of coal dust. All were overloaded and many sank. It
854-483: A dilute solution of gold(III) chloride or chlorauric acid . Unlike sulfur, phosphorus reacts directly with gold at elevated temperatures to produce gold phosphide (Au 2 P 3 ). Gold readily dissolves in mercury at room temperature to form an amalgam , and forms alloys with many other metals at higher temperatures. These alloys can be produced to modify the hardness and other metallurgical properties, to control melting point or to create exotic colors. Gold
976-579: A gold-from-seawater swindle in the United States in the 1890s, as did an English fraudster in the early 1900s. Fritz Haber did research on the extraction of gold from sea water in an effort to help pay Germany 's reparations following World War I . Based on the published values of 2 to 64 ppb of gold in seawater, a commercially successful extraction seemed possible. After analysis of 4,000 water samples yielding an average of 0.004 ppb, it became clear that extraction would not be possible, and he ended
1098-830: A golden hue to metallic caesium . Common colored gold alloys include the distinctive eighteen-karat rose gold created by the addition of copper. Alloys containing palladium or nickel are also important in commercial jewelry as these produce white gold alloys. Fourteen-karat gold-copper alloy is nearly identical in color to certain bronze alloys, and both may be used to produce police and other badges . Fourteen- and eighteen-karat gold alloys with silver alone appear greenish-yellow and are referred to as green gold . Blue gold can be made by alloying with iron , and purple gold can be made by alloying with aluminium . Less commonly, addition of manganese , indium , and other elements can produce more unusual colors of gold for various applications. Colloidal gold , used by electron-microscopists,
1220-567: A large alluvial deposit. The mines at Roşia Montană in Transylvania were also very large, and until very recently, still mined by opencast methods. They also exploited smaller deposits in Britain , such as placer and hard-rock deposits at Dolaucothi . The various methods they used are well described by Pliny the Elder in his encyclopedia Naturalis Historia written towards the end of
1342-563: A newspaper in Yukon "the best of luck in rolling out a quality product." The "Save the Star" campaign was paused after raising $ 17,000. Fraser said he will proceed with "Plan B" to launch a new publication, but would return all money raised if the newspaper failed to materialize. The Star's building in downtown Whitehorse was put up sale and emptied before July. The Yukon Star launched with five former Whitehorse Star staffers hired. The publication

#17327718907191464-462: A novel type of metal-halide perovskite material consisting of Au and Au cations in its crystal structure has been found. It has been shown to be unexpectedly stable at normal conditions. Gold pentafluoride , along with its derivative anion, AuF − 6 , and its difluorine complex , gold heptafluoride , is the sole example of gold(V), the highest verified oxidation state. Some gold compounds exhibit aurophilic bonding , which describes
1586-823: A remote area, made the control of the borders a sensitive issue. Early on in the gold rush, the US Army sent a small detachment to Circle City, in case intervention was required in the Klondike, while the Canadian government considered excluding all American prospectors from the Yukon Territory. Neither eventuality took place and instead the US agreed to make Dyea a sub-port of entry for Canadians, allowing British ships to land Canadian passengers and goods freely there, while Canada agreed to permit American miners to operate in
1708-401: A sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 28 square metres (300 sq ft). Gold leaf can be beaten thin enough to become semi-transparent. The transmitted light appears greenish-blue because gold strongly reflects yellow and red. Such semi-transparent sheets also strongly reflect infrared light, making them useful as infrared (radiant heat) shields in
1830-423: A soluble tetrachloroaurate anion . Gold is insoluble in nitric acid alone, which dissolves silver and base metals , a property long used to refine gold and confirm the presence of gold in metallic substances, giving rise to the term ' acid test '. Gold dissolves in alkaline solutions of cyanide , which are used in mining and electroplating . Gold also dissolves in mercury , forming amalgam alloys, and as
1952-520: A solution of Au(OH) 3 in concentrated H 2 SO 4 produces red crystals of gold(II) sulfate , Au 2 (SO 4 ) 2 . Originally thought to be a mixed-valence compound, it has been shown to contain Au 4+ 2 cations, analogous to the better-known mercury(I) ion, Hg 2+ 2 . A gold(II) complex, the tetraxenonogold(II) cation, which contains xenon as a ligand, occurs in [AuXe 4 ](Sb 2 F 11 ) 2 . In September 2023,
2074-574: A well-known American scout and explorer, arrived from Africa, only to be called back to take part in the Second Boer War . Among those who documented the rush was the Swedish-born photographer Eric Hegg , who took some of the iconic pictures of Chilkoot Pass, and reporter Tappan Adney , who afterwards wrote a first-hand history of the stampede. Jack London , later a famous American writer, left to seek for gold but made his money during
2196-460: A wheel, which pulled a rope running to the top and back; freight was loaded on sledges pulled by the rope. Five more tramways soon followed, one powered by a steam engine , charging between 8 and 30 cents ($ 2 and $ 8) per 1 pound (0.45 kg). An aerial tramway was built in the spring of 1898, able to move 9 tonnes of goods an hour up to the summit. At Lakes Bennett and Lindeman, the prospectors camped to build rafts or boats that would take them
2318-470: Is Au with a half-life of 2.27 days. Gold's least stable isomer is Au with a half-life of only 7 ns. Au has three decay paths: β decay, isomeric transition , and alpha decay. No other isomer or isotope of gold has three decay paths. The possible production of gold from a more common element, such as lead , has long been a subject of human inquiry, and the ancient and medieval discipline of alchemy often focused on it; however,
2440-696: Is Au , which decays by proton emission with a half-life of 30 μs. Most of gold's radioisotopes with atomic masses below 197 decay by some combination of proton emission , α decay , and β decay . The exceptions are Au , which decays by electron capture, and Au , which decays most often by electron capture (93%) with a minor β decay path (7%). All of gold's radioisotopes with atomic masses above 197 decay by β decay. At least 32 nuclear isomers have also been characterized, ranging in atomic mass from 170 to 200. Within that range, only Au , Au , Au , Au , and Au do not have isomers. Gold's most stable isomer
2562-648: Is also known, an example of a mixed-valence complex . Gold does not react with oxygen at any temperature and, up to 100 °C, is resistant to attack from ozone: Au + O 2 ⟶ ( no reaction ) {\displaystyle {\ce {Au + O2 ->}}({\text{no reaction}})} Au + O 3 → t < 100 ∘ C ( no reaction ) {\displaystyle {\ce {Au{}+O3->[{} \atop {t<100^{\circ }{\text{C}}}]}}({\text{no reaction}})} Some free halogens react to form

#17327718907192684-520: Is also used in infrared shielding, the production of colored glass , gold leafing , and tooth restoration . Certain gold salts are still used as anti-inflammatory agents in medicine. Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. Such nanowires distort via the formation, reorientation, and migration of dislocations and crystal twins without noticeable hardening. A single gram of gold can be beaten into
2806-427: Is always richer at the exposed surface of gold-bearing veins, owing to the oxidation of accompanying minerals followed by weathering; and by washing of the dust into streams and rivers, where it collects and can be welded by water action to form nuggets. Gold sometimes occurs combined with tellurium as the minerals calaverite , krennerite , nagyagite , petzite and sylvanite (see telluride minerals ), and as
2928-517: Is attributed to wind-blown dust or rivers. At 10 parts per quadrillion, the Earth's oceans would hold 15,000 tonnes of gold. These figures are three orders of magnitude less than reported in the literature prior to 1988, indicating contamination problems with the earlier data. A number of people have claimed to be able to economically recover gold from sea water , but they were either mistaken or acted in an intentional deception. Prescott Jernegan ran
3050-470: Is found in ores in rock formed from the Precambrian time onward. It most often occurs as a native metal , typically in a metal solid solution with silver (i.e. as a gold/silver alloy ). Such alloys usually have a silver content of 8–10%. Electrum is elemental gold with more than 20% silver, and is commonly known as white gold . Electrum's color runs from golden-silvery to silvery, dependent upon
3172-472: Is most often called the oldest since this treasure is the largest and most diverse. Gold artifacts probably made their first appearance in Ancient Egypt at the very beginning of the pre-dynastic period, at the end of the fifth millennium BC and the start of the fourth, and smelting was developed during the course of the 4th millennium; gold artifacts appear in the archeology of Lower Mesopotamia during
3294-542: Is now questioned. The gold-bearing Witwatersrand rocks were laid down between 700 and 950 million years before the Vredefort impact. These gold-bearing rocks had furthermore been covered by a thick layer of Ventersdorp lavas and the Transvaal Supergroup of rocks before the meteor struck, and thus the gold did not actually arrive in the asteroid/meteorite. What the Vredefort impact achieved, however,
3416-427: Is red if the particles are small; larger particles of colloidal gold are blue. Gold has only one stable isotope , Au , which is also its only naturally occurring isotope, so gold is both a mononuclidic and monoisotopic element . Thirty-six radioisotopes have been synthesized, ranging in atomic mass from 169 to 205. The most stable of these is Au with a half-life of 186.1 days. The least stable
3538-451: Is responsible for The Star adopting its official motto, " Illegitimus non Carborundum ", a Dog Latin aphorism meaning "You mustn't let the bastards grind you down". The motto is incorporated into the newspaper's logo, and is displayed on its website. Jackie Pierce owned the Whitehorse Star from 2002 until her death in 2023. In April 2024, the newspaper announced it will cease and publish its final edition on May 17 after efforts to sell
3660-484: Is similarly unaffected by most bases. It does not react with aqueous , solid , or molten sodium or potassium hydroxide . It does however, react with sodium or potassium cyanide under alkaline conditions when oxygen is present to form soluble complexes. Common oxidation states of gold include +1 (gold(I) or aurous compounds) and +3 (gold(III) or auric compounds). Gold ions in solution are readily reduced and precipitated as metal by adding any other metal as
3782-589: Is the soluble form of gold encountered in mining. The binary gold halides , such as AuCl , form zigzag polymeric chains, again featuring linear coordination at Au. Most drugs based on gold are Au(I) derivatives. Au(III) (referred to as auric) is a common oxidation state, and is illustrated by gold(III) chloride , Au 2 Cl 6 . The gold atom centers in Au(III) complexes, like other d compounds, are typically square planar , with chemical bonds that have both covalent and ionic character. Gold(I,III) chloride

3904-657: Is thought to have been delivered to Earth by asteroid impacts during the Late Heavy Bombardment , about 4 billion years ago. Gold which is reachable by humans has, in one case, been associated with a particular asteroid impact. The asteroid that formed Vredefort impact structure 2.020 billion years ago is often credited with seeding the Witwatersrand basin in South Africa with the richest gold deposits on earth. However, this scenario
4026-511: Is thought to have been produced in supernova nucleosynthesis , and from the collision of neutron stars , and to have been present in the dust from which the Solar System formed. Traditionally, gold in the universe is thought to have formed by the r-process (rapid neutron capture) in supernova nucleosynthesis , but more recently it has been suggested that gold and other elements heavier than iron may also be produced in quantity by
4148-416: Is unaffected by most acids. It does not react with hydrofluoric , hydrochloric , hydrobromic , hydriodic , sulfuric , or nitric acid . It does react with selenic acid , and is dissolved by aqua regia , a 1:3 mixture of nitric acid and hydrochloric acid . Nitric acid oxidizes the metal to +3 ions, but only in minute amounts, typically undetectable in the pure acid because of the chemical equilibrium of
4270-571: The Chilkat Pass some miles west of Chilkoot and turned north to the Yukon River, a distance of about 350 miles (560 km). This was created by Jack Dalton as a summer route, intended for cattle and horses, and Dalton charged a toll of $ 250 ($ 6,800) for its use. The Takou route started from Juneau and went north-east to Teslin Lake. From here, it followed a river to the Yukon, where it met
4392-666: The Chu (state) circulated the Ying Yuan , one kind of square gold coin. In Roman metallurgy , new methods for extracting gold on a large scale were developed by introducing hydraulic mining methods, especially in Hispania from 25 BC onwards and in Dacia from 106 AD onwards. One of their largest mines was at Las Medulas in León , where seven long aqueducts enabled them to sluice most of
4514-474: The Klondike region of Yukon in northwestern Canada, between 1896 and 1899. Gold was discovered there by local miners on August 16, 1896; when news reached Seattle and San Francisco the following year, it triggered a stampede of prospectors . Some became wealthy, but the majority went in vain. It has been immortalized in films, literature, and photographs. To reach the gold fields, most prospectors took
4636-507: The North-West Mounted Police (NWMP) introduced safety rules, vetting the boats carefully and forbidding women and children to travel through the rapids. Additional rules stated that any boat carrying passengers required a licensed pilot , typically costing $ 25 ($ 680), although some prospectors simply unpacked their boats and let them drift unmanned through the rapids with the intent of walking down to collect them on
4758-602: The Old Testament , starting with Genesis 2:11 (at Havilah ), the story of the golden calf , and many parts of the temple including the Menorah and the golden altar. In the New Testament , it is included with the gifts of the magi in the first chapters of Matthew. The Book of Revelation 21:21 describes the city of New Jerusalem as having streets "made of pure gold, clear as crystal". Exploitation of gold in
4880-502: The Panic of 1893 and Panic of 1896 , which caused unemployment and financial uncertainty. There was a huge, unresolved demand for gold across the developed world that the Klondike promised to fulfil and, for individuals, the region promised higher wages or financial security. Psychologically, the Klondike, as historian Pierre Berton describes, was "just far enough away to be romantic and just close enough to be accessible". Furthermore,
5002-658: The Varna Necropolis near Lake Varna and the Black Sea coast, thought to be the earliest "well-dated" finding of gold artifacts in history. Several prehistoric Bulgarian finds are considered no less old – the golden treasures of Hotnitsa, Durankulak , artifacts from the Kurgan settlement of Yunatsite near Pazardzhik , the golden treasure Sakar, as well as beads and gold jewelry found in the Kurgan settlement of Provadia – Solnitsata ("salt pit"). However, Varna gold

5124-567: The chemical symbol Au (from Latin aurum ) and atomic number 79. In its pure form, it is a bright , slightly orange-yellow, dense, soft, malleable , and ductile metal . Chemically, gold is a transition metal , a group 11 element , and one of the noble metals . It is one of the least reactive chemical elements, being the second-lowest in the reactivity series . It is solid under standard conditions . Gold often occurs in free elemental ( native state ), as nuggets or grains, in rocks , veins , and alluvial deposits . It occurs in
5246-470: The reducing agent . The added metal is oxidized and dissolves, allowing the gold to be displaced from solution and be recovered as a solid precipitate. Less common oxidation states of gold include −1, +2, and +5. The −1 oxidation state occurs in aurides, compounds containing the Au anion . Caesium auride (CsAu), for example, crystallizes in the caesium chloride motif; rubidium, potassium, and tetramethylammonium aurides are also known. Gold has
5368-580: The "back door to the Klondike". One, the "overland route", headed north-west from Edmonton, ultimately meeting the Peace River and then continuing on overland to the Klondike, crossing the Liard River en route. To encourage travel via Edmonton, the government hired T.W. Chalmers to build a trail, which became known as the Klondike Trail or Chalmers Trail. The other two trails, known as
5490-609: The "water routes", involved more river travel. One went by boat along rivers and overland to the Yukon River system at Pelly River and from there to Dawson. Another went north of Dawson by the Mackenzie River to Fort McPherson , before entering Alaska and meeting the Yukon River at Fort Yukon , downstream to the Klondike. From here, the boat and equipment had to be pulled up the Yukon about 400 miles (640 km). An estimated 1,660 travellers took these three routes, of whom only 685 arrived, some taking up to 18 months to make
5612-613: The Alaskan side of the border, Circle City , a logtown , was established in 1893 on the Yukon River. In three years it grew to become "the Paris of Alaska", with about 1,200 inhabitants, saloons, opera houses, schools, and libraries. In 1896, it was so well-known that a correspondent from the Chicago Daily Record came to visit. At the end of the year, it became a ghost town , when large gold deposits were found upstream on
5734-488: The Chilkoot and White Passes. These units were armed with Maxim guns . Their tasks included enforcing the rules requiring that travellers bring a year's supply of food with them to be allowed into the Yukon Territory, checking for illegal weapons, preventing the entry of criminals and enforcing customs duties. This last task was particularly unpopular with American prospectors, who faced paying an average of 25 percent of
5856-614: The Dyea and Skagway route at a point halfway to the Klondike. It meant dragging and poling canoes up-river and through mud together with crossing a 5,000 feet (1,500 m) mountain along a narrow trail. Finally, there was the Stikine route starting from the port of Wrangell further south-east of Skagway. This route went up the uneasy Stikine River to Glenora, the head of navigation . From Glenora, prospectors would have to carry their supplies 150 miles (240 km) to Teslin Lake where it, like

The remainder mostly found themselves stranded in isolated camps and settlements along the ice-covered river often in desperate circumstances. Most of the prospectors landed at the southeast Alaskan towns of Dyea and Skagway, both located at the head of the natural Lynn Canal at
6100-524: The Klondike during the gold rush. Instead, the miners relied on wood fires to soften the ground to a depth of about 14 inches (360 mm) and then remove the resulting gravel. The process was repeated until the gold was reached. In theory, no support of the shaft was necessary because of the permafrost although in practice sometimes the fire melted the permafrost and caused collapses. Fires could also produce harmful gases, which had to be removed by bellows or other tools. The resulting "dirt" brought out of
6222-558: The Klondike for the new goldfields, marking the end of the Klondike Rush. The boom towns declined, and the population of Dawson City fell. Gold mining production in the Klondike peaked in 1903 after heavier equipment was brought in. Since then, the Klondike has been mined on and off, and its legacy continues to draw tourists to the region and contribute to its prosperity. The indigenous peoples in north-west America had traded in copper nuggets prior to European expansion . Most of

#17327718907196344-450: The Klondike, a layer of hard permafrost lay only 6 feet (1.8 m) below the surface. Traditionally, this had meant that mining in the region only occurred during the summer months, but the pressure of the gold rush made such a delay unacceptable. Late 19th-century technology existed for dealing with this problem, including hydraulic mining and stripping, and dredging . Still, the heavy equipment required for this could not be brought into
6466-481: The Klondike. On August 16, 1896, an American prospector named George Carmack and two Tagish men, Skookum Jim (Keish), and Tagish Charlie (K̲áa Goox̱) were travelling south of the Klondike River. Following a suggestion from Robert Henderson , a Canadian prospector, they began looking for gold on Bonanza Creek , then called Rabbit Creek, one of the Klondike's tributaries. It is not clear who discovered
6588-463: The Klondike. Both decisions were unpopular among their domestic publics: American businessmen complained that their right to a monopoly on regional trade was being undermined, while the Canadian public demanded action against the American miners. The North-West Mounted Police set up control posts at the borders of the Yukon Territory or, where that was disputed, at easily controlled points such as
6710-605: The Native Tlingit and Tagish tribes, the early prospectors opened the important routes of Chilkoot and White Pass and reached the Yukon valley between 1870 and 1890. Here, they encountered the Hän people, semi-nomadic hunters and fishermen who lived along the Yukon and Klondike Rivers. The Hän did not appear to know about the extent of the gold deposits in the region. In 1883, Ed Schieffelin identified gold deposits along
6832-635: The Pacific ports closest to the gold strikes were desperate to encourage trade and travel to the region. The mass journalism of the period promoted the event and the human interest stories that lay behind it. A worldwide publicity campaign engineered largely by Erastus Brainerd , a Seattle newspaperman, helped establish that city as the premier supply centre and the departure point for the gold fields. The prospectors came from many nations, although an estimated majority of 60 to 80 percent were Americans or recent immigrants to America. Most had no experience in
6954-653: The Stikine River route at Glenora. From Glenora, prospectors would face the same difficulties as those who came from Wrangell. At least 1,500 men attempted to travel along the Ashcroft route and 5,000 along the Stikine. The mud and the slushy ice of the two routes proved exhausting, killing or incapacitating the pack animals and creating chaos amongst the travellers. Three more routes started from Edmonton , Alberta ; these were not much better – barely trails at all – despite being advertised as "the inside track" and
7076-747: The Takou route, met the Yukon River system. An alternative to the South-east Alaskan ports were the All-Canadian routes, so-called because they mostly stayed on Canadian soil throughout their journey. These were popular with British and Canadians for patriotic reasons and because they avoided American customs. The first of these, around 1,000 miles (1,600 km) in length, started from Ashcroft in British Columbia and crossed swamps, river gorges , and mountains until it met with

Packers, prepared to carry supplies for cash, were available along the route but would charge up to $ 1 ($ 27) per lb (0.45 kg) on the later stages; many of these packers were natives: Tlingits or, less commonly, Tagish. Avalanches were common in the mountains and, on April 3, 1898, one claimed
7320-467: The Yukon River, and an expedition up the Fortymile River in 1886 discovered considerable amounts of it and founded Fortymile City. The same year gold had been found on the banks of the Klondike River, but in small amounts and with no claims being made. By late 1886, several hundred miners were working their way along the Yukon valley, living in small mining camps and trading with the Hän. On
7442-586: The Yukon in the summer from the delta until a point called Whitehorse, above the Klondike. Travel, in general, was made difficult by both terrain and climate. The region was mountainous, the rivers winding and sometimes impassable; summers, albeit short, still brought heat, while during the long winters, temperatures could drop below −50 °C (−58 °F). Aids for the travellers to carry their supplies varied; some had brought dogs, horses, mules , or oxen, whereas others had to rely on carrying their equipment on their backs or on sleds pulled by hand. Shortly after

Geologically, the region was permeated with veins of gold, forced to the surface by volcanic action and then worn away by the action of rivers and streams, leaving nuggets and gold dust in deposits known as placer gold . Some ores lay along the creek beds in lines of soil, typically 15 feet (4.6 m) to 30 feet (9.1 m) beneath

7808-1409: The corresponding gold halides. Gold is strongly attacked by fluorine at dull-red heat to form gold(III) fluoride AuF 3 . Powdered gold reacts with chlorine at 180 °C to form gold(III) chloride AuCl 3 . Gold reacts with bromine at 140 °C to form a combination of gold(III) bromide AuBr 3 and gold(I) bromide AuBr, but reacts very slowly with iodine to form gold(I) iodide AuI: 2 Au + 3 F 2 → Δ 2 AuF 3 {\displaystyle {\ce {2Au{}+3F2->[{} \atop \Delta ]2AuF3}}} 2 Au + 3 Cl 2 → Δ 2 AuCl 3 {\displaystyle {\ce {2Au{}+3Cl2->[{} \atop \Delta ]2AuCl3}}} 2 Au + 2 Br 2 → Δ AuBr 3 + AuBr {\displaystyle {\ce {2Au{}+2Br2->[{} \atop \Delta ]AuBr3{}+AuBr}}} 2 Au + I 2 → Δ 2 AuI {\displaystyle {\ce {2Au{}+I2->[{} \atop \Delta ]2AuI}}} Gold does not react with sulfur directly, but gold(III) sulfide can be made by passing hydrogen sulfide through
7930-424: The densest element, osmium , is 22.588 ± 0.015 g/cm . Whereas most metals are gray or silvery white, gold is slightly reddish-yellow. This color is determined by the frequency of plasma oscillations among the metal's valence electrons, in the ultraviolet range for most metals but in the visible range for gold due to relativistic effects affecting the orbitals around gold atoms. Similar effects impart
8052-689: The early 4th millennium. As of 1990, gold artifacts found at the Wadi Qana cave cemetery of the 4th millennium BC in West Bank were the earliest from the Levant. Gold artifacts such as the golden hats and the Nebra disk appeared in Central Europe from the 2nd millennium BC Bronze Age . The oldest known map of a gold mine was drawn in the 19th Dynasty of Ancient Egypt (1320–1200 BC), whereas
8174-485: The end of the Inside Passage. From there, they needed to travel over the mountain ranges into Canada's Yukon Territory, and then down the river network to the Klondike. Along the trails, tent camps sprung up at places where prospectors had to stop to eat or sleep or at obstacles such as the icy lakes at the head of the Yukon. At the start of the rush, a ticket from Seattle to the port of Dyea cost $ 40 ($ 1,100) for
8296-498: The end of the trail. Even using a heavy sled, a strong man would be covering 1,000 miles (1,600 km) and need around 90 days to reach Lake Bennett. Those who landed at Dyea, Skagway's neighbour town, travelled the Chilkoot Trail and crossed its pass to reach Lake Lindeman, which fed into Lake Bennett at the head of the Yukon River. The Chilkoot Pass was higher than the White Pass, but more used it: around 22,000 during
8418-613: The final 500 miles (800 km) down the Yukon to Dawson City in the spring. 7,124 boats of varying size and quality left in May 1898; by that time, the forests around the lakes had been largely cut down for timber. The river posed a new problem. Above Whitehorse , it was dangerous, with several rapids along the Miles Canyon through to the White Horse Rapids. After many boats were wrecked and several hundred people died,
8540-591: The first written reference to gold was recorded in the 12th Dynasty around 1900 BC. Egyptian hieroglyphs from as early as 2600 BC describe gold, which King Tushratta of the Mitanni claimed was "more plentiful than dirt" in Egypt. Egypt and especially Nubia had the resources to make them major gold-producing areas for much of history. One of the earliest known maps, known as the Turin Papyrus Map , shows
8662-403: The gold acts simply as a solute, this is not a chemical reaction . A relatively rare element, gold is a precious metal that has been used for coinage , jewelry , and other works of art throughout recorded history . In the past, a gold standard was often implemented as a monetary policy . Gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard
8784-511: The gold reached Circle City. Despite the winter, many prospectors immediately left for the Klondike by dog-sled, eager to reach the region before the best claims were taken. The outside world was still largely unaware of the news, and although Canadian officials had managed to send a message to their superiors in Ottawa about the finds and influx of prospectors, the government did not give it much attention. The winter prevented river traffic, and it
8906-435: The gold rush, only around 15,000 to 20,000 finally became prospectors. Of these, no more than 4,000 struck gold and only a few hundred became rich. By the time most of the stampeders arrived in 1898, the best creeks had all been claimed, either by the long-term miners in the region or by the first arrivals of the year before. The Bonanza, Eldorado, Hunker, and Dominion Creeks were all taken, with almost 10,000 claims recorded by
9028-493: The gold rush. The trail passed up through camps until it reached a flat ledge, just before the main ascent, which was too steep for animals. This location was known as the Scales, and was where goods were weighed before travellers officially entered Canada. The cold, the steepness and the weight of equipment made the climb extremely arduous and it could take a day to get to the top of the 1,000 feet (300 m) high slope. As on
9150-443: The gold: George Carmack or Skookum Jim, but the group agreed to let George Carmack appear as the official discoverer because they feared that authorities would not recognize an indigenous claimant. In any event, gold was present along the river in huge quantities. Carmack measured out four strips of ground for mining along the river - two for himself as the discoverer and one each for Jim and Charlie. These claims were registered
9272-400: The ground of vegetation and debris. Prospect holes were then dug in an attempt to find the ore or "pay streak". If these holes looked productive, proper digging could commence, aiming down to the bedrock, where the majority of the gold was found. The digging would be carefully monitored in case the operation needed to be shifted to allow for changes in the flow. In the sub-Arctic climate of
9394-563: The highest electron affinity of any metal, at 222.8 kJ/mol, making Au a stable species, analogous to the halides . Gold also has a –1 oxidation state in covalent complexes with the group 4 transition metals, such as in titanium tetraauride and the analogous zirconium and hafnium compounds. These chemicals are expected to form gold-bridged dimers in a manner similar to titanium(IV) hydride . Gold(II) compounds are usually diamagnetic with Au–Au bonds such as [ Au(CH 2 ) 2 P(C 6 H 5 ) 2 ] 2 Cl 2 . The evaporation of
9516-435: The journey. An equivalent to the All-Canadian routes was the "All-American route", which aimed to reach the Yukon from the port of Valdez , which lay further along the Alaskan coast from Skagway. This, it was hoped, would evade the Canadian customs posts and provide an American-controlled route into the interior. From late 1897 onwards 3,500 men and women attempted it; delayed by the winter snows, fresh efforts were made in
9638-467: The lives of more than 60 people travelling over Chilkoot Pass. Entrepreneurs began to provide solutions as the winter progressed. Steps were cut into the ice at the Chilkoot Pass which could be used for a daily fee, this 1,500 step staircase becoming known as the "Golden Steps". By December 1897, Archie Burns built a tramway up the final parts of the Chilkoot Pass. A horse at the bottom turned
9760-547: The mineral quartz, and gold out of the fluids and onto nearby surfaces. The world's oceans contain gold. Measured concentrations of gold in the Atlantic and Northeast Pacific are 50–150 femtomol /L or 10–30 parts per quadrillion (about 10–30 g/km ). In general, gold concentrations for south Atlantic and central Pacific samples are the same (~50 femtomol/L) but less certain. Mediterranean deep waters contain slightly higher concentrations of gold (100–150 femtomol/L), which
9882-416: The mines froze quickly in winter and could be processed only during the warmer summer months. An alternative, more efficient, approach called steam thawing was devised between 1897 and 1898; this used a furnace to pump steam directly into the ground, but since it required additional equipment it was not a widespread technique during the years of the rush. Gold Gold is a chemical element with
10004-404: The mining industry, being clerks or salesmen. Mass resignations of staff to join the gold rush became notorious. In Seattle, this included the mayor, twelve policemen, and a significant percentage of the city's streetcar drivers. Some stampeders were famous: John McGraw , the former governor of Washington, joined, together with the prominent lawyer and sportsman A. Balliot. Frederick Burnham ,
10126-574: The mountainous terrain and cold climate meant that most of those who persisted did not arrive until the summer of 1898. Once there, they found few opportunities, and many left disappointed. To accommodate the prospectors, boom towns sprang up along the routes. At their terminus, Dawson City was founded at the confluence of the Klondike and Yukon rivers. From a population of 500 in 1896, the town grew to house approximately 17,000 people by summer 1898. Built of wood, isolated, and unsanitary, Dawson suffered from fires, high prices, and epidemics. Despite this,
10248-613: The next day at the police post at the mouth of the Fortymile River and news spread rapidly from there to other mining camps in the Yukon River valley. By the end of August, all of Bonanza Creek had been claimed by miners. A prospector then advanced up into one of the creeks feeding into Bonanza, later to be named Eldorado Creek . He discovered new sources of gold there, which would prove to be even richer than those on Bonanza. Claims began to be sold between miners and speculators for considerable sums. Just before Christmas, word of
10370-411: The noble metals, it still forms many diverse compounds. The oxidation state of gold in its compounds ranges from −1 to +5, but Au(I) and Au(III) dominate its chemistry. Au(I), referred to as the aurous ion, is the most common oxidation state with soft ligands such as thioethers , thiolates , and organophosphines . Au(I) compounds are typically linear. A good example is Au(CN) − 2 , which
10492-402: The northwest. Guidebooks were published, giving advice about routes, equipment, mining, and capital necessary for the enterprise. The newspapers of the time termed this phenomenon "Klondicitis". The Klondike could be reached only by the Yukon River, either upstream from its delta, downstream from its head, or from somewhere in the middle through its tributaries. River boats could navigate
10614-472: The other side. During the summer, a horse-powered rail-tramway was built by Norman Macaulay, capable of carrying boats and equipment through the canyon at $ 25 ($ 680) a time, removing the need for prospectors to navigate the rapids. There were a few more trails established during 1898 from South-east Alaska to the Yukon River. One was the Dalton trail: starting from Pyramid Harbour, close to Dyea, it went across
10736-536: The paper failed and following years of financial difficulties. In response, ex- Star journalist Max Fraser launched the "Save the Star" fundraising campaign on Indiegogo with the goal to raise $ 400,000 to either buy the Star, or if the effort failed, start a new publication called the Yukon Star. The Star' s owners said they will not sell and will close the business as planned. They wished anyone who wanted to start
10858-401: The pass had to be done in stages. Most divided their belongings into 65 pounds (29 kg) packages that could be carried on a man's back, or heavier loads that could be pulled by hand on a sled. Ferrying packages forwards and walking back for more, a prospector would need about thirty round trips, a distance of at least 2,500 miles (4,000 km), before they had moved all of their supplies to
10980-537: The physical paper's size and the number of pages. Circulation rose to 2,300. Bain sold the paper to Harry Boyle of Vancouver in October 1954. Boyle bought a Linotype machine for the paper from the Dawson Weekly News , which had closed. The press was replaced in 1960 by a used Harris offset printing press which a year later allowed The Star to start publishing twice a week on Mondays and Thursdays. Boyle
11102-576: The plan of a gold mine in Nubia together with indications of the local geology . The primitive working methods are described by both Strabo and Diodorus Siculus , and included fire-setting . Large mines were also present across the Red Sea in what is now Saudi Arabia . Gold is mentioned in the Amarna letters numbered 19 and 26 from around the 14th century BC. Gold is mentioned frequently in
11224-464: The project. The earliest recorded metal employed by humans appears to be gold, which can be found free or " native ". Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period, c. 40,000 BC . The oldest gold artifacts in the world are from Bulgaria and are dating back to the 5th millennium BC (4,600 BC to 4,200 BC), such as those found in
11346-690: The r-process in the collision of neutron stars . In both cases, satellite spectrometers at first only indirectly detected the resulting gold. However, in August 2017, the spectroscopic signatures of heavy elements, including gold, were observed by electromagnetic observatories in the GW170817 neutron star merger event, after gravitational wave detectors confirmed the event as a neutron star merger. Current astrophysical models suggest that this single neutron star merger event generated between 3 and 13 Earth masses of gold. This amount, along with estimations of
11468-620: The rare bismuthide maldonite ( Au 2 Bi ) and antimonide aurostibite ( AuSb 2 ). Gold also occurs in rare alloys with copper , lead , and mercury : the minerals auricupride ( Cu 3 Au ), novodneprite ( AuPb 3 ) and weishanite ( (Au,Ag) 3 Hg 2 ). A 2004 research paper suggests that microbes can sometimes play an important role in forming gold deposits, transporting and precipitating gold to form grains and nuggets that collect in alluvial deposits. A 2013 study has claimed water in faults vaporizes during an earthquake, depositing gold. When an earthquake strikes, it moves along
11590-420: The rate of occurrence of these neutron star merger events, suggests that such mergers may produce enough gold to account for most of the abundance of this element in the universe. Because the Earth was molten when it was formed , almost all of the gold present in the early Earth probably sank into the planetary core . Therefore, as hypothesized in one model, most of the gold in the Earth's crust and mantle
11712-935: The reaction. However, the ions are removed from the equilibrium by hydrochloric acid, forming AuCl − 4 ions, or chloroauric acid , thereby enabling further oxidation: 2 Au + 6 H 2 SeO 4 → 200 ∘ C Au 2 ( SeO 4 ) 3 + 3 H 2 SeO 3 + 3 H 2 O {\displaystyle {\ce {2Au{}+6H2SeO4->[{} \atop {200^{\circ }{\text{C}}}]Au2(SeO4)3{}+3H2SeO3{}+3H2O}}} Au + 4 HCl + HNO 3 ⟶ HAuCl 4 + NO ↑ + 2 H 2 O {\displaystyle {\ce {Au{}+4HCl{}+HNO3->HAuCl4{}+NO\uparrow +2H2O}}} Gold
11834-473: The rest of the gold on Earth is thought to have been incorporated into the planet since its very beginning, as planetesimals formed the mantle . In 2017, an international group of scientists established that gold "came to the Earth's surface from the deepest regions of our planet", the mantle, as evidenced by their findings at Deseado Massif in the Argentinian Patagonia . On Earth, gold
11956-540: The route the informal name of Dead Horse Trail. The volumes of travellers and the wet weather made the trail impassable and, by late 1897, it was closed until further notice, leaving around 5,000 stranded in Skagway. An alternative toll road suitable for wagons was eventually constructed and this, combined with colder weather that froze the muddy ground, allowed the White Pass to reopen, and prospectors began to make their way into Canada. Moving supplies and equipment over
12078-630: The route through the ports of Dyea and Skagway in southeast Alaska . Here, the "Klondikers" could follow either the Chilkoot or White Pass trail to the Yukon River and sail down to the Klondike. The Canadian authorities required each person to bring a year's supply of food in order to prevent starvation. In all, the Klondikers' equipment weighed close to a ton, which most carried themselves in stages. Performing this task and contending with
12200-520: The rush mostly by working for prospectors. Seattle and San Francisco competed fiercely for business during the rush, with Seattle winning the larger share of trade. Indeed, one of the first to join the gold rush was William D. Wood, the mayor of Seattle, who resigned and formed a company to transport prospectors to the Klondike. The publicity around the gold rush led to a flurry of branded goods being marketed. Clothing, equipment, food, and medicines were all sold as "Klondike" goods, allegedly designed for
12322-486: The same result and showing that the isotopes of gold produced by it were all radioactive . In 1980, Glenn Seaborg transmuted several thousand atoms of bismuth into gold at the Lawrence Berkeley Laboratory. Gold can be manufactured in a nuclear reactor, but doing so is highly impractical and would cost far more than the value of the gold that is produced. Although gold is the most noble of
12444-486: The silver content. The more silver, the lower the specific gravity . Native gold occurs as very small to microscopic particles embedded in rock, often together with quartz or sulfide minerals such as " fool's gold ", which is a pyrite . These are called lode deposits. The metal in a native state is also found in the form of free flakes, grains or larger nuggets that have been eroded from rocks and end up in alluvial deposits called placer deposits . Such free gold
12566-450: The south-east corner of the Black Sea is said to date from the time of Midas , and this gold was important in the establishment of what is probably the world's earliest coinage in Lydia around 610 BC. The legend of the golden fleece dating from eighth century BCE may refer to the use of fleeces to trap gold dust from placer deposits in the ancient world. From the 6th or 5th century BC,
12688-580: The spring. In practice, the huge Valdez glacier that stood between the port and the Alaskan interior proved almost insurmountable and only 200 managed to climb it; by 1899, the cold and scurvy was causing many deaths amongst the rest. Other prospectors attempted an alternative route across the Malaspina Glacier just to the east, suffering even greater hardships. Those who did manage to cross it found themselves having to negotiate miles of wilderness before they could reach Dawson. Their expedition
12810-518: The stampede began in 1897, the Canadian authorities had introduced rules requiring anyone entering Yukon Territory to bring with them a year's supply of food; typically this weighed around 1,150 pounds (520 kg). By the time camping equipment, tools and other essentials were included, a typical traveller was transporting as much as a ton in weight. Unsurprisingly, the price of draft animals soared; at Dyea, even poor quality horses could sell for as much as $ 700 ($ 19,000), or be rented out for $ 40 ($ 1,100)
12932-460: The surface. Others, formed by even older streams, lay along the hilltops; these deposits were called "bench gold". Finding the gold was challenging. Initially, miners had assumed that all the gold would be along the existing creeks, and it was not until late in 1897 that the hilltops began to be mined. Gold was also unevenly distributed, which made the prediction of good mining sites uncertain without exploratory digging. Mining began with clearing
13054-436: The tendency of gold ions to interact at distances that are too long to be a conventional Au–Au bond but shorter than van der Waals bonding . The interaction is estimated to be comparable in strength to that of a hydrogen bond . Well-defined cluster compounds are numerous. In some cases, gold has a fractional oxidation state. A representative example is the octahedral species {Au( P(C 6 H 5 ) 3 )} 2+ 6 . Gold
13176-403: The transmutation of the chemical elements did not become possible until the understanding of nuclear physics in the 20th century. The first synthesis of gold was conducted by Japanese physicist Hantaro Nagaoka , who synthesized gold from mercury in 1924 by neutron bombardment. An American team, working without knowledge of Nagaoka's prior study, conducted the same experiment in 1941, achieving
13298-475: The tribes were aware that gold existed in the region, but the metal was not valued by them. The Russians and the Hudson's Bay Company had both explored the Yukon in the first half of the 19th century, but ignored the rumours of gold in favour of fur trading , which offered more immediate profits. In the second half of the 19th century, American prospectors began to spread into the area. Making deals with
13420-422: The value of their goods and supplies. The Mounties had a reputation for running these posts honestly, although accusations were made that they took bribes. Prospectors, on the other hand, tried to smuggle prize items like silk and whiskey across the pass in tins and bales of hay: the former item for the ladies, the latter for the saloons. Of the estimated 30,000 to 40,000 people who reached Dawson City during
13542-417: The visors of heat-resistant suits and in sun visors for spacesuits . Gold is a good conductor of heat and electricity . Gold has a density of 19.3 g/cm , almost identical to that of tungsten at 19.25 g/cm ; as such, tungsten has been used in the counterfeiting of gold bars , such as by plating a tungsten bar with gold. By comparison, the density of lead is 11.34 g/cm , and that of
13664-453: The wealthiest prospectors spent extravagantly, gambling and drinking in the saloons . The indigenous Hän , on the other hand, suffered from the rush; they were forcibly moved into a reserve to make way for the Klondikers, and many died. Beginning in 1898, the newspapers that had encouraged so many to travel to the Klondike lost interest in it. In the summer of 1899, gold was discovered around Nome in west Alaska , and many prospectors left
13786-787: Was abandoned for a fiat currency system after the Nixon shock measures of 1971. In 2020, the world's largest gold producer was China, followed by Russia and Australia. As of 2020 , a total of around 201,296 tonnes of gold exist above ground. This is equal to a cube, with each side measuring roughly 21.7 meters (71 ft). The world's consumption of new gold produced is about 50% in jewelry, 40% in investments , and 10% in industry . Gold's high malleability, ductility, resistance to corrosion and most other chemical reactions, as well as conductivity of electricity have led to its continued use in corrosion-resistant electrical connectors in all types of computerized devices (its chief industrial use). Gold
13908-432: Was expensive and long – 4,700 miles (7,600 km) in total – it had the attraction of speed and avoiding overland travel. At the beginning of the stampede a ticket could be bought for $ 150 ($ 4,050) while during the winter 1897–98 the fare settled at $ 1,000 ($ 27,000). In 1897, some 1,800 travellers attempted this route but the vast majority were caught along the river when the region iced over in October. Only 43 reached
14030-520: Was forced to turn back the same way they had come, with only four men surviving. The borders in South-east Alaska were disputed between the US, Canada and Britain since the American purchase of Alaska from Russia in 1867. The US and Canada both claimed the ports of Dyea and Skagway. This, combined with the numbers of American prospectors, the quantities of gold being mined and the difficulties in exercising government authority in such
14152-421: Was issued twice a week for a time, and then three times a week in the 1960s and five times a week from around 1980 to 1982. In 1982, the paper changed to publishing three times a week. The paper returned to publishing five times a week in 1985 until 2019. In 2022 it adopted a Monday-Wednesday-Friday print schedule, with updates on the website on other days. The afternoon newspaper, usually available after 3 p.m., had
14274-485: Was joined by outfitters, writers and photographers. Various factors lay behind this sudden mass response. Economically, the news had reached the US at the height of a series of financial recessions and bank failures in the 1890s. The gold standard of the time tied paper money to the production of gold and shortages towards the end of the 19th century meant that gold dollars were rapidly increasing in value ahead of paper currencies and being hoarded. This had contributed to
14396-503: Was not until June 1897 that the first boats left the area, carrying the freshly mined gold and the full story of the discoveries. In the resulting Klondike stampede, an estimated 100,000 people tried to reach the Klondike goldfields, of whom only around 30,000 to 40,000 eventually did. It formed the height of the Klondike gold rush from the summer of 1897 until the summer of 1898. It began on July 14, 1897, in San Francisco and
14518-405: Was online-only at first but began publishing in print weekly starting in May 2024. The Yukon Star ceased after four months due to lack of funds. Flo Whyard , who has served as the mayor of Whitehorse, is among the newspaper's former editors. When it was founded in 1900, the newspaper appeared only once a week, and its progress to Monday through Friday publication occurred in fits and starts; it
14640-465: Was possible to sail all the way to the Klondike, first from Seattle across the northern Pacific to the Alaskan coast. From St. Michael , at the Yukon River delta, a river boat could then take the prospectors the rest of the way up the river to Dawson, often guided by one of the Native Koyukon people who lived near St. Michael. Although this all-water route, also called "the rich man's route",
14762-487: Was spurred further three days later in Seattle , when the first of the early prospectors returned from the Klondike, bringing with them large amounts of gold on the ships Excelsior and Portland . The press reported that a total of $ 1,139,000 (equivalent to $ 1 billion at 2010 prices) had been brought in by these ships, although this proved to be an underestimate. The migration of prospectors caught so much attention that it
14884-621: Was to distort the Witwatersrand basin in such a way that the gold-bearing rocks were brought to the present erosion surface in Johannesburg , on the Witwatersrand , just inside the rim of the original 300 km (190 mi) diameter crater caused by the meteor strike. The discovery of the deposit in 1886 launched the Witwatersrand Gold Rush . Some 22% of all the gold that is ascertained to exist today on Earth has been extracted from these Witwatersrand rocks. Much of
