Gunman Property

The Gunman Property is a zinc and silver mine located in White Pine county, Nevada at an elevation of 6,594 feet.

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.

Mine Info

Satelite View

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.

Land Status

Land ownership: BLM Administrative Area
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.

Comments

Comment (Development): WMC drilled the property in 1990-1991. In May 2000, Mid-North and Cypress Development Corp. completed a 3,025 ft drill program at the Gunman property. Selected results include hole GM-01 grading 4.91% zinc and 32.86 g/t Ag over 100 ft and hole GM-02 grading 3.54% zinc and 5.7 g/t silver over 165 ft. In November of that year, Cypress reported assays from reverse circulation holes drilled in the RH Zone of its Gunman property in Nevada. The highest grade reported occurs in hole GM-26 between 85 and 95 feet depths where 19.08 % Zn and 90.5 g/t Ag were intersected.At that time 8900 feet of a planned 15,000 feet for Phase III had been drilled. In 2002, Cypress Development announced a formal joint venture agreement with Mid-North Resources for the Gunman property in which Cypress will be the operator with a 70% interest and Mid-North holding the remaining 30% interest in the property. Mapping and drilling was ongoing in early 2004 on the property. At that time (June 2004) , Cypress had completed 5,500 feet of reverse circulation drilling that include 19 R-C drill holes that step out approximately 2,000 feet to test the NNW extension of the high-grade zinc oxide RH zone, and 1 step out R-C drill hole has been completed so far, to test the SSE extension. Drilling continues to outline a zinc-bearing carbonate replacement envelope surrounding the high-grade RH Zone. This envelope covers an area of at least 600 metres long and 200 metres wide. Cypress?s efforts are currently focused on extending the high-grade core of the system. All drill holes to date, have encountered the same altered oxidized carbonate replacement host rock found in the RH Zone. This drilling could increase the potential size and scale of the RH Zone. The Company anticipates its phase 1 work program will include 30 R-C drill holes, drilled from 18 sites, for a total of approximately 9,000 feet. The Company anticipates releasing all assays from the first 20 drill holes later in June 2004. In 2006, Cypress Development Corp. holds a 73.13% interest, Bison Gold Exploration Inc. 26.87%, in the 2,400 acres Gunman Zinc-Silver Project. At that time, the two drill programs completed by Cypress Development on the Gunman property included 26,000 feet of drilling, which returned some spectacular drill intercepts with grades reaching up to 37% zinc over 5.0 feet, and 26.8% zinc and 8 oz per ton silver over 75 feet.

Comment (Economic Factors): Reserves for the property have not yet been calculated and released, but rough calculations indicated that geologic resources of zinc and silver in the deposit may approach the thresholds for inclusion in the significant deposit database.

Comment (Identification): Although reserves and resources have not yet been caculated, this project approaches the threshold values for zinc and silver for inclusion in significant deposit database.

Comment (Deposit): The mineralization is shallow occurring mainly between the surface and 300 foot depth and consists of a high-grade zinc oxide zone surrounded by a zinc-bearing carbonate replacement envelope. The RH Zone is a tabular body of intensely oxidized, zinc-silver mineralization of apparent carbonate replacement origin. The zinc mineralization is primarily zinc oxide (smithsonite). As partially delineated by the 2000 drill program, the RH Zone is approx. 300 feet long (NNW), 150 feet wide (ENE), and about 80 feet thick starting at or near surface and continues to be open along strike in both directions. Drilling has indicated that mineralization occurs in vertical bodies within a flat lying oxidized zone up to 300 feet thick extending down from the surface. The immediate drill target now covers an area at least 2000 feet long by 500 feet wide. Drilling within this envelope is currently targeting features identified during a Self Potential (SP) survey carried out in 2001 that showed very distinct signatures over the high-grade RH Zone and the RH South Zone. The SP survey showed classic responses from the upper oxidized zone and over sulfides in the lower reduced part of the section. Proximity to strong north trending faults appears to be a controlling factor on grade distribution. The mineralization discovered on the Gunman Project to date, strongly resembles the oxide zinc-silver-lead-gold bonanzas that have been historically mined in the Eureka district, located 40 miles SSW of the Gunman property.

Comment (Location): The Gunman property consists of 120 Federal lode claims totaling 2,400 acres, located on the east flank of the Diamond Range, between Horse Canyon on the south and Big Canyon on the north. The property is immediately adjacent to a paved highway and to electrical power. UTM is centered on the RH Zone; the RH South zone lies about 2500 meters SSW of the RH zone.

Comment (Workings): The property is in an area previously unmined but just north of a few old shafts and prospect pits shown on the topographic map. The current prospect is developed by surface prospecting and drilling.

Comment (Commodity): Ore Materials: smithsonite, zinc oxide, sulfides

Comment (Commodity): Gangue Materials: calcite

Nevada Gold

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: Gold Districts of Nevada.
