Gold Ridge Project

Lease Status: Available

Exploration Target: Very shallow sediment-hosted gold mineralization.

Property Highlights:

  • Gold Ridge has strong surface gold mineralization within the upper portions of excellent stratigraphy that remains undrilled.
  • There are surface rock chips up to 3.6 g/t gold; shallow drilling has been conducted only in immediate vicinity of a master range-front fault or its footwall, no drilling has tested the pediment target area.
  • The system is quite large, measuring at least 4 miles by 2 miles, much of this untested pediment with shallow cover.
  • This an excellent situation for target identification by structural and stratigraphic mapping along with geophysical targeting in shallow cover.

Location and Land:

Gold Ridge is located in the Walker Lane in Esmeralda County, NV about x miles from Goldfield. The land is all BLM available for the location of any number of mining claims. The climate of the area is warm and dry, and should be available for year round exploration. There are no known environmental concerns on the project area. Genesis currently has a small land position and will require a significant AOI in any proposed agreement.

Exploration Target:

The Gold Ridge gold mineralization is hosted by altered Cambrian sedimentary rocks. It has some visual similarities to Carlin-type systems (jasperoid and decalcification) but the correlation of gold with quartz veinlets suggest it may have epithermal characteristics. The large pediment area demonstrates that the project has considerable size potential.

Geology:

The Gold Ridge project is located in a shallow pediment area east of the X District. Cambrian sedimentary units are exposed in small buttes in this pediment area, which represents the hangingwall of a major range-bounding fault. The Cambrian units are mainly the uppermost part of the Poleta Formation and the lower Harkless Formation. The Poleta Fm is comprised of a lower limestone unit, a very prospective middle calcareous clastic unit, and an upper limestone unit. The Harkless Formations consists mainly of sandstone and siltstone with minor limestone and is dominantly non-calcareous. Almost all of these isolated buttes display alteration consisting of jasperoid, decalcification, iron oxides, and quartz veinlets. Rock chips there show numerous plus 100 ppb gold values, up to 2.6 ppm gold (see map).

Rock units in the major fault footwall are pre-Cambrian dolomite, siliceous siltstone, limestone, and sandstone, limy siltstone, and quartzite. Mafic and felsic dikes cut all units in both the footwall and hangingwall of the range-bounding fault. Along the fault and in the immediate footwall are strong alteration and gold mineralization. Alteration there consists of jasperoid, quartz veinlets, bleaching, and argillization with gold values up to 3.6 ppm gold.

History and Results:

The Gold Ridge property was explored by X Resources from 1987 to 1991. Work during this period included mapping, rock chip sampling, trenching, a CSAMT survey, and the drilling of 21 reverse circulation drill holes. X collected 562 rock chip samples and the author more than 130. Assays are available for 459 X samples. Of these, 39 contained over 0.300 ppm gold, with those 39 averaging 0.820 ppm Au. Arsenic and mercury values are generally high while antimony and silver values are subdued.

Drill depths ranged from 100 feet to 500 feet total depth. The best result was 40 feet of 0.660 ppm gold. All drilling was near the fault zone or in the footwall of it. The furthest from the fault zone into the hangingwall was about 300 feet.

Potential and Exploration Scenario:

The Gold Ridge project shows a very large area of prospective stratigraphy with widespread strong geochemical gold values in rock chips. The best target area appears to be in the pediment area that forms the hangingwall of the major fault zone (see Section A). Exposures there are sporadic but demonstrate strong gold values and very favorable stratigraphy. Most of the exposures are upper Poleta Fm or lowermost Harkless, indicating that the prospective middle Poleta is at shallow depths (see section) An exploration program that emphasizes good structural and stratigraphic mapping followed by a good geophysical program could yield very compelling targets at very shallow depths.
