Dome Hill (NV-CA)
Property Overview
The Dome Hill project is situated on the Nevada-California border, approximately 36 miles (58 km) southwest of Hawthorne, NV in the Walker Lane mineral belt. The project consists of 147 unpatented claims owned by Nevoro Nevada Inc. in addition to 5 unpatented claims and 1 patented claim each subject to a separate underlying lease/option agreement. The project is subject to an Amended Exploration and Option Agreement dated effective February 10, 2010 between Nevoro Nevada Inc. and Golden Predator Mines US Inc., ("GPUS") whereby GPUS has an option to earn up to a 75% interest in the project. There are also two underlying lease/option agreements.
Historical Exploration
The Bodie district, approximately 19 miles (30.6 km) south of the property, was discovered in the 1860's, and prospectors working the area soon discovered gold at Aurora and Masonic as well as mercury in hot springs sinter at Paramount. Most of the production from the Masonic district was from the Pittsburgh-Liberty, Pierinni and Maybell mines which are credited with about 35,000 ounces of gold. Other operations around Masonic produced an estimated 25,000 ounces of gold. All production was from small, near surface, underground operations, and by the 1940's mining activity had ceased. Beginning in the mid 1970's, private individuals began staking some of the more obvious altered areas in both California and Nevada.
Only two previous companies have staked claims in the area of the property, and only one company, is known to have permitted drilling on the property. Three reclaimed drill sites have been found, but no drill data has been located. Also, several shallow rotary drill holes from the 1980's are located on the southern extension of the Maybell zone and suspected to have tested for near-surface, bulk-mineable targets, and were not adequate tests of the epithermal vein target.
Mineralization and Geology
Five mineralized, northeast-trending, epithermal, acid-sulfate veins have been identified on the property that have strike lengths of up to 7,500 feet (ft) (2,300 metres (m)), as demonstrated in the Maybell zone, and widths varying from 10 to 200 ft (3 to 60 m). Siliceous, hydrothermal breccias in the core of the veins contain up to 0.92 ounce per ton (opt) (31.8 grams per tonne (gpt)) gold. The style and intensity of the district-scale alteration zones surrounding the veins suggest the potential for porphyry-style mineralization at depth.
Regionally, the Dome Hill property is part of the Western Andesite Assemblage that was deposited along a subduction-related continental margin arc and erupted mostly within the Walker Lane Belt transtensional zone. These volcanic rocks have been dated from 23 Ma to 8 Ma and are host to some historic, major precious metals mining districts including the famous Comstock Lode and the Bodie District. Historic productions from the Comstock Lode are 8.4 million ounces Au and 193 million ounces silver and from the nearby Bodie District (30 km from Dome Hill) some 1.46 million ounces gold and 7.28 million ounces silver was produced.
Current Work
The Company has received approval for a plan of operations from the U. S. Forest Service to drill from up to 18 sites on the property in 2010 and is mobilizing to begin drilling in the second quarter of the year. A phased exploration drilling program is planned to test the four major vein systems, with the initial work to explore the strongest areas of mineralization. A second phase of drilling will follow if results warrant.
Summary of Results
Geological mapping, rock chip geochemistry and geophysical surveys have shown that the Dome Hill property is host to a robust acid-sulfate style epithermal veins system associated with Tertiary rhyolite and dacite flow domes. Historic mining has taken place along the four major veins exposed on the property with numerous subsidiary veins also having been prospected by shallow shafts and adits. The project is located within a larger area of intense hydrothermal alteration and precious metal mineralization with the potential to host multiple vein hosted gold-silver deposits. Structural mapping has illustrated that the veins are controlled by the Walker Lane tectonic shear zone with favorable orientations on the veins located perpendicular to the trend of the right lateral Walker Lane trend.
