About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Austin Gold Ventures Gold Mine MRDS details
Primary: Austin Gold Ventures Gold Mine
Secondary: Dry Canyon Deposit
Secondary: Quito Mine

Land ownership: National Forest
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Mineral Deposit Model
Model Name: Sediment-hosted Au
Form: The four major ore zones are all very narrow, tabular, concentrated along pre-existing structures and about 3600 feet long.
Description: Shallow thrust faults, normal faults and folding have affected the rocks in the mine area.
Description: The deposit is located in the Birch Creek window through the Roberts Mountains Thrust.
Alteration Type: L
Alteration Text: The deposit is distinctive in its lack of significant hydrothermal alteration of wall rocks. It lacks intense silicification or clay alteration. Small amounts of pyrite, sericite and clay are common in wallrock adjacent to veins, but are not extensively developed.
Description: phyllitic argillaceous
Age Type: Host Rock
Age Young: Ordovician

Comment (Commodity): Gangue Materials: quartz, calcite
Comment (Commodity): Ore Materials: FREE GOLD, AURIFEROUS PYRITE AND ARSENOPYRITE
Comment (Geology): The deposit is located in a window of the Roberts Mountains Thrust. Rocks in the mine area include Cambrian to Devonian eastern-facies carbonate rocks exposed in a window through transitional to western-facies siliceous rocks of the Valmy Formation. Known ore-grade mineralization is controlled by the intersection of steeply-dipping faults with structurally prepared favorable host lithologies. While eastern facies carbonate rocks are the best ore host rocks, traces of gold have been intercepted in drill holes in western facies rocks. The deposit consists of four major ore zones, all very narrow and about 3600 feet in strike length. There is strong structural control of the thin quartz-calcite veinlets and gold mineralization. Veinlets range from microscopic to 15 cm in width, concentrated along pre-existing structures.
Comment (Identification): This is the same property as MRDS record No. W700418, and MRDS record No. M242948 from which all information was incorporated into this record. Records No. W700418 and M242948 should be deleted as duplicate records.
Comment (Location): The deposit is located on the east side of the Toiyabe Range, at the headwaters of Birch Creek. The mill site is on the west side of the Toiyabe Range near the mouth of Dry Creek. UTM is to near the center of the main pit.

Comment (Development): First called the Quito prospect, Austin was a ?grass-roots? discovery by FMC Gold Corporation (Meridian Gold's predecessor) in 1980. FMC staked 648 unpatented lode claims on the prospect from 1980 to 1983. FMC also leased 5 patented claims and one millsite for the property. In 1984, FMC entered into a joint venture with Minorco, in which FMC kept a 28% interest, and Minorco was the operator with 72%. In 1985 Inspiration Inc. and FMC Minerals Corp. formed a joint venture called the Austin Gold Venture to develop the deposit. Morrison-Knudsen was awarded the contract for mining services (1986). The plan was to haul 350000 tons ore per year over the crest of the Toiyabes and down Dry Canyon on the west side to a mill in the Reese River Valley. Planned production (1985) of 55000 ounces of gold per year. Start-up was scheduled for mid-May, 1986. The projected mine life was 5 years. Austin Gold Ventures controlled a large claim block surrounding the mine area. First gold was poured in December 1986. The mine employed 121 persons in 1986. Stripping ratio for main pit was greater than 12:1. Ore was mined primarily through open pit methods with a very limited amount of ore delivered from an underground test mine. A total of one million tons of ore were processed through a mill. Tailings were deposited in a clay lined facility. Mine closure was followed by reclamation which was to include closure and rehabilitation of the access road. However, the community expressed an interest in leaving the road open for recreation access to the mountains, so Meridian worked directly with the community, the county and Forest Service to modify the closure plan and leave the road open, which Austin has identified as a feature that would compliment bicycle tourism in the area. By 1989, the deposit was mined out, having produced 191,000 ounces of gold from 1986 through 1989. White Knight Gold began exploration of the Quito area in the late 1990s and in 1999, USFS reported that White Knight Gold was planning a 2-3-year exploration project inthat would include road building and drilling in three separate areas in the Birch Creek drainage peripheral to the formerly mined Quito property: the Russ Southwest area (11 drill sites); the Q-4 area (6 holes); and the Spires area (new road building and up to 17 holes). The drilling project was still pending USFS approval in 2001.
Comment (Economic Factors): Production from 1986 to 1989 was 4.25 metric tonnes of gold and an unknown amount of silver from 933 kilotonnes of ore. The deposit produced 191,000 ounces of gold from 1986 through 1989. Remaining resources at that time were 4.2 metric tonnes of gold and an unknown amount of silver contained in 609 kilotonnes of ore.
Comment (Workings): The mine is developed by a multiple bench open pit covering 14 acres. Ore is treated in a flotation mill, followed by agitated cyanide leaching of flotation tailings. There is a satellite pit about 1/4 mile to the south of the main open pit. Currently proposed drilling is in areas peripheral to the existing mined area.

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more at Gold Districts of Nevada.
