Bull Project 

Lease Status: Available

Exploration Target: Shallow Carlin style gold deposit mineralization in very active district.

Property Highlights:

  • Bull has strong surface gold mineralization local area favored host rocks, the Pilot Shale/Joanna Limestone group.
  • Drilling in small area (300m x 300m) by BHP Minerals in the early 90s intersected strong gold mineralization with up to 30 feet at 1.15 g/t Au included in 85 feet at 0.542 g/t Au.
  • Large shallow pediment area in a prolific district.

Location and Land:

Bull is located in southwest White Pine County, Nevada, about 33 kilometers southeast of Eureka. This area has prolific gold mineralization and within the vicinity of the project are several current or past producing sediment hosted gold deposits : the Pan mine being currently operated by Fiore Gold is 8 kilometers southwest; the Easy Junior past producer and Gold Rock project under development by Fiore is about 17 kilometers south, the past producing Mt Hamilton mine is 12 miles southeast, and the past producing and current exploration project Green Springs mine is 23 kilometers southeast (Figure 1). The land is all BLM land.  GenGold2 currently has 100 claims in the project area.

Deposit Type/Analog:

The Bull gold mineralization is typical Carlin-type gold mineralization, with gold associated with jasperoid development and a barite vein (Figure 2). The apparent target unit will be the Pilot Shale, the host rock at the nearby Pan and Green Springs mines.

Geology:

The Bull project is situated on isolated outcrops of Joanna Limestone, Chainman Shale, and Diamond Peak Formation (Figure 3). These outcrops protrude through a thin pediment cover, as indicated by gravity data the number scattered small Paleozoic outcrops. Alteration at the surface consists of jasperoid, altered shale and a barite vein. Areas of jasperoid float occur about 0.5 kilometers to the northwest and have not been drill tested.

Gravity data (Figure 4.) and scattered bedrock occurrences indicate that the project area situated over a pediment area with very shallow post-mineral alluvial cover.

History and Results:

The Bull project was found and explored by BHP Minerals in the early 1990s with fifteen drill holes (Figure 3).  Results of these holes are shown in Table 1 below.  A BHP map indicates 8 more drill sites were planned, but it is not known if they were drilled.  Newcrest Minerals explored the area and conducted a gravity survey, a magnetic survey, and planned some drill holes.  It is not known if any of those holes were drilled or what the results may have been.

 

Potential and Exploration Scenario:

The Bull project has great potential to host near-surface Carlin-type gold deposits. Ore grades are known to exist, the right host rocks are present, and depths to mineralized zones should be moderate. The drill intercepts could be in Chainman Shale, with the more productive Pilot Shale below.  The project represents an excellent opportunity to define several hundred thousand ounces of near-surface, oxidized gold ore.
