Description

The Green Talc Mine is a gold mining property located in Mineral County, Nevada. The mine is well off the beaten path and rarely visited or surveyed. Originally located as a source of andalusite, the operators quickly noted the presence of Copper and Gold in some small quantities.

As the mine was developed, miners located large veins of oxidized copper sulfide veins. These veins were largely vertical and were reported as columns, some up to 15’ in width and an undetermined depth. Miners explored to the 200’ level with no ending in site. The copper contained small bits of free gold, when crushed and floated, resulting in gold values of up to one (1) ounce per ton.

The Green Talc is a sister mine to the Dover Mine which is located a short distance to the west. The two properties were once owned by the same company.

Named the Green Talc for the green clay that is present from the surface to at least 15’ depth, the mine produced a total of 450 tons of Andalusite prior to 1920 which was used for high-temperature refining applications.

From 40 to 200’ in depth, the miners found oxidized copper with pyrite and gold. Using flotation methods the ore was able to produce roughly one ounce of gold per ton and 7 lbs of copper. Ore reported being worth up to $30 per ton in gold and copper values.

Surveyors examined the site in 2017 and noted that the drift and other underground workings had been blocked but the mine was otherwise in excellent repair and did not appear to have been picked over.

Samples of auriferous pyrite were noted. Handpicked samples were taken from the dump and near the portal entrances for assay work. Values were widely varied from only a trace of gold in some samples to 1.11 oz/T in other samples.

There is much work to be completed to determine the actual values of the site and the potential for large scale gold mining viability. The site has an excellent rating from surveyors based on the samples taken.

The gold in this mine is found in small particulates, most notably in columns of ore near quartz and oxidized copper deposits. The copper is heavily oxidized but contains pyrites and some free gold. Gold will be processed from this mine by chemical separation. The gold is too small to be recovered by conventional methods.

There are a variety of buildings in states of disrepair on the claim. An old workshop, a large tipple with an office built on top. The office has collapsed but the tipple still stands. The claim is remote and at the end of a dead-end road. There are no resources available on the claim or in the general area.

This claim should be considered for miners with some advanced knowledge of processing and separation. It is likely there will be a Notice of Operation required to profitably work the site. A high volume of material would likely need to be processed to show reasonable returns.
