Gold Basin, Arizona (Mohave County) is a historic gold mining district and geographic basin in northwestern Arizona, located in the southern White Hills west of Hualapai Wash (also spelled Wallapai), south of Lake Mead and west of the Grand Wash Cliffs. It lies roughly 50–60 miles north of Kingman and about 70 miles southeast of Las Vegas, Nevada. The area is part of the Basin and Range province and is closely associated with the adjacent Lost Basin mining district to the northeast across Hualapai Valley.
Early Discovery and Lode Mining (1870s–1900s)
Gold-bearing quartz veins were first discovered in the early 1870s. Development was slow due to extreme remoteness, scarce water and fuel, and limited transportation. Before 1900 the district produced an estimated $50,000–$100,000 in gold (period values), most of it from the Eldorado (or El Dorado) Mine, the earliest significant producer.
A small boom occurred around 1880. By 1881 two stamp mills were operating; one was a cooperative five-stamp mill at Grass Springs (near the later Diamond Bar Ranch headquarters), and another was built near Red Willow Spring. Most of the important early mines—Eldorado, Excelsior, Golden Rule, Jim Blaine, Never-Get-Left, O.K., and Cyclopic—had been located and developed by 1883. These produced free-milling gold-quartz ores averaging 0.5–3.0 ounces of gold per ton.
Around 1886 a third stamp mill was built along Hualapai Wash and became the nucleus of a small settlement called Gold Basin (later also known simply as Basin). Gold-bearing veins in the neighboring Lost Basin district were discovered about the same time. The Gold Basin mill (also called the O.K. or Burnt Mill) became the region’s central processing facility. Water had to be piped roughly 10 km from tunnels at Patterson’s Well because local wells hit only dry alluvium. The mill burned in 1893, was rebuilt in 1896 with 10 stamps plus a cyanide plant, and burned again in 1906; it was not rebuilt after the second fire.
A post office operated at Gold Basin from September 20, 1890, to January 4, 1894. It reopened under the name Basin on March 17, 1904, and closed permanently on June 15, 1907, after which postal service shifted to the Cyclopic Mine (which had its own post office until 1917). The settlement consisted of shanties and tents for miners and mill workers and never grew into a substantial town because of the harsh conditions and distance from supply lines.
Production and Later Lode Activity
Recorded production from the Gold Basin and Lost Basin districts combined (1901–1942) totaled about 13,508 ounces of gold and 6,857 ounces of silver (plus minor copper and lead), valued at roughly $359,000 (98% from gold). Most lode production is credited to Gold Basin mines. Minimum total historic gold production for the Gold Basin district alone is estimated at about 15,000 ounces, predominantly from lode sources.
Activity continued on a small scale into the 1910s–1920s, then largely paused until the early 1930s. A few mines reopened between 1932 and 1942 before wartime restrictions and later dormancy set in. Ore occurs in veins within Precambrian granite and schist; gold is associated with lead or copper minerals (pyrite, chalcopyrite, galena, molybdenite, wolframite) and, in oxidized zones, limonite, malachite, and other secondary minerals. Mineralization is linked to Late Cretaceous two-mica magmatism and structural features, including a regional low-angle detachment surface.
Key historic mines included the Eldorado, O.K., Cyclopic (which became a population center after 1905 with its own cyanide mill), Excelsior, and others. Modern exploration (including work by companies such as Gold Basin Resources) has focused on oxide gold potential at deposits such as Cyclopic and Stealth, with historical drilling and permitting for open-pit heap-leach concepts that were not advanced due to gold prices at the time.
Placer Mining Boom (1930s onward)
Placer gold was noted as early as 1909, but systematic placer mining did not begin until 1931–1932, roughly 60 years after the lode discoveries. In May 1932 W.E. Dunlop located significant placers; by August about 100 men were working the area with dry washers. Numbers dropped to around 43 by mid-1933. The richest and most active placers were on the east flank of the Lost Basin Range (especially the King Tut placers and nearby claims such as Queen Tut, Golden Nugget, and Lone Jack) and on the detrital fan in Gold Basin itself (including the Searles placer).
Gold ranges from fine dust to coarse nuggets (up to several ounces; a 4-ounce nugget valued at $140 was recovered near King Tut in 1941). Gravels are typically thin (1–3 feet or less) and rest on caliche-cemented material. Most work has been small-scale with portable dry washers; a few operations used power equipment and dry-concentrating plants. Activity has continued intermittently at a small scale into modern times, making the district popular with recreational prospectors using metal detectors and dry washers.
Geology and Landscape
The district lies in rugged desert terrain of rocky hills, dry washes, and alluvial fans. Lode gold occurs in quartz veins (and some episyenitic pipes) hosted by Proterozoic rocks, with emplacement ages primarily Late Cretaceous (and some older resetting). Placer gold is derived from erosion of these veins. The area is arid, with limited water historically a major constraint on development.
Meteorite Strewn Field
In addition to gold, Gold Basin is the site of one of the largest and best-documented meteorite strewn fields in North America. Discovered in 1995 by retired University of Arizona geology professor Jim Kriegh while metal-detecting for gold, the field has yielded thousands of specimens (over 4,450 reported with a total mass exceeding 168 kg in early studies) of an L4 ordinary chondrite (Gold Basin meteorite) across an area of roughly 130–225 km². The terrestrial age is approximately 15,000 ± 600 years (Late Pleistocene). Additional meteorites of other types have also been found in the area. The arid climate has preserved the material well, and fragments are still occasionally recovered by prospectors.
Legacy and Present Day
Gold Basin never became a major boomtown. Its isolation, water scarcity, and relatively modest overall production limited growth. Remains include the ruins of the Burnt Mill (O.K./Gold Basin Mill), stone foundations and concrete slabs of the old mining camp, and a small abandoned cemetery (Gold Basin/Basin/Burnt Mill Ranch Cemetery) with a few wooden markers. The area is primarily public (BLM) land with active mining claims; recreational gold prospecting and meteorite hunting continue. Access is via dirt roads off Pierce Ferry Road (from U.S. Highway 93 north of Kingman). The district remains of interest for both historic mining heritage and modern small-scale exploration and recreation.
Primary sources for this history include U.S. Geological Survey reports (especially Professional Paper 1361 and Bulletin 1355 on placer deposits), Western Mining History compilations of USGS data, and local historical accounts of the settlement, mill, and cemetery.
