Green Monster Property: A Legacy with Modern Potential
The Wildhorse Project is a grassroots stage discovery of polymetallic mineralization associated with the margins of a felsic, porphyritic intrusion of probable Tertiary age. The discovery was made by compilation of data including Anaconda Copper data, NURE stream sediment data and county scale geologic mapping.
A single mineralized skarn zone was initially located in the dumps of shallow, historic workings. Now called the Rattlesnake Zone, assays of dump and working face samples returned 1 gram gold with >1% copper, >100 ppm silver along with very anomalous antimony (to 7000 ppm), bismuth and tungsten (to 350 ppm).
A staking decision was made based on the assay results of these initial grab and chip samples. Two additional zones of outcropping copper mineralization were located during claim staking. The so-called Coca Cola Zone is a very shallow prospect pit with massive chrysocolla mineralization associated with quartz veining within a strongly altered porphyritic wall rock.
Very dense, cola brown veins and disseminations occur with the copper mineralization. This mineral is abundant in the grab samples obtained. No assays have been done yet but microscope work and other testing of the brown material strongly suggests the mineral is in the wolframite group. Wolframite is a well-known tungsten mineral that contains 70% weight percent tungsten.
The third known zone is located in the higher elevation portion of the property and consists of a relatively large surface working. No detailed geologic observations of this zone have been made.
The three zones cover an area > 1 square kilometer and all appear to be localized along margins of the felsic porphyry intrusion. The first pass geologic model suggests robust skarn, quartz vein and porphyry hosted mineralization in the central portion of the claims.
A work program is eagerly anticipated to define the mineralogy of the three zones as well as to explore for further mineralization along the margins and within the central porphyry intrusive.
