Our Boys In Blue Claims; NBMG Sample Sites 1743, 1744
Structure: Abundant Normal Faults Shear Zones
Commodity: Cu ore mineral not given in the literature
Deposit: Prominent, resistant, silicified vein outcrop about 3 ft high, 7 ft in outcrop length, 2-3 ft wide, composed of Fe-and Mn-stained silicified quartzite cut by a network of quartz veins. Difficult to distinguish quartzite from quartz vein, As quartzite is silicified and opalized and quartz vein is very finely crystalline, sugary to massive. The "rib" strikes n55 W and dips steeply SW to vertical. Portions of the vein are brecciated and indicate emplacement along a fault. The deposit is in quartzite, but brown, marly, fetid recrystallized limestone is exposed in a small prospect north of the shaft. Limonitic and Mn-rich gossan was sampled from the dump. Gossan is heavy siliceous or earthy and contains some boxworks and opaline coatings. Pink, fine-grained quartzite contains numerous drusy quartz-lined yugs and siliceous veinlets deposited within fractures with very fine-grained oxidized pyrite.
Development: No activity at time of examination in 1983.
Geology: Cu stained shear zones near top of prospect mountain quartzite.
Ore(s): Fault Zone (?); Brecciation
