Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): VERY SMALL PEGMATITE

Comment (Deposit): Property also consistes of a granite pegmatite dike with some beryl (Bull. 71, p. 43).

Comment (Geology): "This pegmatite is in preCambrian shcist and ocntains chiefly quartz, microcline and muscovite, with accessory albite. Punhc and scrap quality mica is visible in a pit 25 ft to 30 ft long, 8 to 10 ft wide, and 3 to 4 ft deep. The dike trends N55W." (Bull. 50, p. 71). "Large garnets, some of which weigh over 2 lbs have been found in a biotite schist body near the Ione Prospect. Most crystals do not show good crystal faces and are not of gem quality." (Bull. 50 p. 76).
