Geology:
The Tokop project, now being interpreted as Tokop North and Tokop South, hosts more than one style of gold mineralization and host rock. Tokop North is a reduced intrusive-related gold (“RIRG”) system hosted in granitoids and carbonate units, while Tokop South is typical Walker Lane-style epithermal mineralization hosted in Tertiary volcanics (Ammonia Tanks tuff) as well as Wyman Formation carbonate. This style of mineralization is more akin to ore deposits approximately 30 miles south and east of the project like those of the Bullfrog District. Deposits of the Bullfrog District (surrounding Beatty, Nevada) are low-sulfidation, volcanic and sedimentary-hosted, epithermal gold deposits like the Bullfrog Mine operated by Barrick Gold which produced over 2.3 million ounces of gold and 3.0 million ounces of silver from 1989 – 1999 from open pit and underground workings.
The RIRG model is similar to large mines in the Tintina Gold Belt of central Alaska and contiguous parts of the Yukon. The best known and most economically important of these include Fort Knox, Pogo gold mine and the Eagle Mine of the Dublin Gulch Properties in the Yukon At Tokop, similar to those mines, sheeted quartz veins in a multi-phase, reduced, calc-alkaline granitoid intrusive as well as surrounding metamorphosed sedimentary rocks, coupled with widespread hydrothermal alteration, may host gold mineralization of significant potential. Shear-hosted veins extend for nearly two kilometres along strike at Tokop. To date, sampling of these vein systems returned grades of up to 71.73 gpt gold and 970 gpt silver (historical and current sampling).
