Cinch Tungsten

Project Summary

Historical resource of 75,000 tons at 0.41% WO₃ and 25,000 tons at 0.033% WO₃, with the mineralized zone traceable for 500 feet along surface and open and untested at depth. Previous operations shipped hundreds of tons of high-grade tungsten ore during World War II, with individual carloads grading between 0.45% and 0.87% WO₃. The property attracted a follow-on mapping, sampling, and drilling campaign by Union Carbide in 1981. We hold 6 claims.

The Cinch Tungsten project is located in Lincoln County, Nevada approximately 50 road miles south of Ely and 45 miles north of Pioche.

Geology

The project targets brecciated, scheelite-bearing quartz veins and replacement pods within a limestone host along an extensive thrust fault zone. The scheelite-bearing quartz zones vary from one to eight feet in width, averaging 3.5 feet.

Metals contained within the deposit include primary tungsten, with accessory copper; gangue minerals are quartz and coarse crystalline white calcite. Ore minerals include scheelite and powellite. The scheelite is very finely disseminated within quartz vein fragments; owing to this fine-grained character, entire pieces of quartz fluoresce strongly under ultraviolet light even at modest WO₃ content.

In addition to the main workings, systematic sampling across 255 feet of surface outcrop averaging 3.5 feet in width returned 0.50% WO₃, indicating a robust mineralized belt that should expand the resource potential significantly.

Exploration and History

Discovered in 1941 by Owen Walker, the Cinch property was initially developed through a series of pits, open cuts, and underground workings focusing on the main brecciated zone. Early development included 310 feet of surface stripping along the outcrop and two short underground adits. Activity peaked during World War II when the property shipped ore to the Metals Reserve Co. in Salt Lake City before production ceased.

Significant effort was dedicated to the lower adit, where underground sampling identified high-grade mineralization, including a USGS chip sample assaying 1.14% WO₃. Bulk sampling from six carload shipments totalled 302.6 tons at an average grade of 0.64% WO₃, with individual cars returning grades between 0.45% and 0.87% WO₃.

In 1981, Union Carbide initiated a mapping, sampling, and drilling program. Drilling explored an area approximately one-quarter mile north of the main workings, intersecting coarser-grained limestone at depth and a probable intrusive approximately 450 feet below surface. These efforts further advanced the understanding of the property's mineral potential and set the stage for future development.
