The Project’s vein deposits and the several associated veins within the mine are classified as volcanichosted epithermal base and precious metal vein type deposits. These deposits are sometimes referred to as intermediate sulfidation epithermal deposits typically characterized as high in silver and gold with or without base metals, associated with andesite volcanism and structurally controlled.
At Virginius, chalcedonic quartz and cockscomb textures have been observed and late euhedral calcite is found in places. Fluid inclusion studies suggest that boiling did not occur in the system.
Mineralization in the District is found primarily in sub-vertical fissure veins and is classified as a telescoped epithermal quartz vein type deposit. The veins are characterized by somewhat constrained vertical extents generally less than 1,000 ft) and a vertical zoning that favors precious metals in the upper levels grading into more base-metal rich mineralization with depth.
The mineralogy found at the Project is consistent with this type of mineralization and includes galena, sphalerite, tetrahedrite, polybasite, chalcopyrite, pyrite, arsenopyrite, marcasite as well as ferroan rhodonite, calcian-ferroan rhodochrosite, quartz and chlorite.
Virginius Vein System
The most historically productive vein system at the Project is the Virginius and its northern extension, which is sometimes referred to as the Monongahela Vein. Reference to the ........
