Sec 26 T1N R66E
Structure: Thrust Plate Minor Shear Zone

Alteration: Silicification

Commodity: Pyrolusite carries both Ag and au.

Deposit: Black prince fissure, filled with altered Mn-stained ore. Hematite-stained quartz nodules, oxidized pyrite, pyrolusite, slightly magnetic nodules of wad, some carrying crystalline calcite veinlets, slight silicification. Opaline silica coats fracture surfaces and fills vugs. A minor shear zone is exposed at shaft. Limestone on dump is pink (fe oxide-stained ? rhodochrosite?), banded, with crystalline calcite veinlets, and nodules of platy calcite which cement breccia. Values increase with depth. 1981 drill hole data yield an average true thickness of 12.4 ft for the black prince vein at 3.4 oz/t ag. The vein is relatively continous along strike for 2600 ft.

Deposit type: Replacement Mn

Development: Area recently flagged, staked, and drilled (1983) but no production within last several years. In 1983 it was reported that altera resources together with frejonley mining acquired 104 unpatented lode claims of the black prince property for 5.6 million dollars. 15 shallow-angle drill holes were completed on the property in 1981, 12 of which intersected the black prince vein.

Geology: Fissure can be traced 7000 feet on surface in thrust plate of mendha and highland peak formations. An altered granite porphyry dike parallels the fissure footwall. Dike and limestone on footwall also mineralized. Values increase down shaft, ore up to 35 feet thick.

Rock formation(s): Mendha;Highland Peak
