GoldStrike East (Utah) Gold Project

Lease Status: Available

Exploration Target: Very shallow oxidized Carlin style gold deposit mineralization.

Property Highlights:

  • GoldStrike East has strong surface gold mineralization within the middle Claron Formation, just above the productive lower Claron Fm of the Goldstrike (Utah) District. The lower Claron was the host rock to 200,000 ounces of production in the nearby district and is currently producing thick intercepts for Pilot Gold (up to 35m at 2.10 g/t Au in recent releases).
  • There are surface rock chips up to 0.553 g/t gold in a large jasperoid in the middle Claron, along with other scattered anomalies in the middle Claron.
  • The system is quite large, measuring about 8,000 feet in strike length and over 2,000 feet in width, completely untested by drilling.
  • One major shallow drill target is obvious and compelling; others are in sight and just need a modest amount of mapping and sampling to be better defined.

Location and Land:

GoldStrike East is located in southwest about 30 miles northwest of St. George, Utah. The claims are about 3 miles southeast of the main district being drilled by Pilot Gold. 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 within the project area. Genesis currently has a modest land position covering the key targets; additional claims would be warranted to cover the entire prospective area.

Exploration Target:

The GoldStrike East gold mineralization is fairly typical Carlin-type gold mineralization, with gold associated with jasperoid development. This district is unusual in that the host rock is not Paleozoic carbonate rocks but instead is a younger calcareous clastic unit, the Eocene Claron Formation. Mineralization will be expected to be similar to that in the nearby district, where intercepts of oxidized mineralization averaging 1 g/t gold over 100 feet are common. Pilot Gold is actively drilling the main district to great success.

Geology:

The GoldStrike East project is situated on outcropping Claron Formation and units that underlie and overly the Claron (Section and Map). These units all dip moderately to the east and are cut by steep north-northwest and northwest faults.

The Claron Formation can be separated into 3 units: a lower calcareous sandstone/conglomerate unit, a middle red-bed unit of red mudstone, conglomerate, and limestone, and an upper unit largely of lacustrine limestone and volcanic tuffs. The lower Claron unit is the host rock to almost all the gold mineralization in the Goldstrike district. On the Goldstrike East project, gold mineralization is hosted in jasperoids developed in the middle Claron conglomerates. In the main target area, these form a 5 to 15 foot thick stratabound jasperoid cut by northwest faults (Section A and map). Mineralization that extends upward above the aquacludes red mudstone is unusual and considered to be a positive indication. In addition, there is a pyrite-bearing chert bed in the overlying post-Claron rocks that seems to be associated with the gold mineralization that extends throughout the target area.

History and Results:

The GoldStrike District was an oxide, heap leach mine from 1988 to 1994. It produced ~209,000 ounces of gold and ~197,000 ounces silver from 8 million tonnes of ore at an average recovered grade of 1.2 g/t gold from 12 shallow pits.  It closed due to low gold prices. The Goldstrike East area is an extension of the main district and is situated along the same set of arcuate NE to NW trending faults. There has been no known exploration on the Goldstrike East project other than some prospect pits, largely on the sulfide bed which is largely devoid of significant metal values.

 

Potential and Exploration Scenario:

The GoldStrike East project shows a very large area of prospective stratigraphy with widespread strong geochemical gold values in rock chips. The best target area is in an area of extensive jasperoid development above the prospective lower Claron member. Other targets are evident in the project area in other areas of alteration and anomalous geochemistry in the middle Claron member. Specific drill targets can be readily identified here with the relatively simple stratigraphic and structural setting. The project represents an excellent opportunity to define several hundred thousand ounces of near-surface, oxidized gold ore.
