Sec 23 26 T25S R58E Pb Zn Ag Cu Au
Structure: Thrust Faults (Late Jurpssic, Early Tert). Fredrickson Rift Zone; (NW Belt Of Shearing). Shallow Synclinal Fold, Normal Faults, Anticlinal Fold.,

Alteration: Dolomitization

Deposit: There are 2 groups of ore shoots, one with more galena than hydrozincite, and one that has only zinc minerals

Deposit type: Polymetallic replacement

Geology: The workings cut across three different rock types, 1) massive limestone, 2) thinly bedded limestone with lentics of primary chert, 3) and thinly bedded non-cherty limestone. Ore zone closely coincides with contact of thin bedded shaly limestone with massive chert-bearing beds above. Galena forms poorly-defined lenses 6-8 inches thick and 5-10 ft long in breccia zones; in a larger zone up to 50 ft thick.zinc minerals more common in the southern stopes, and galena present there is embedded in the masses of hydrozincite.

Ore(s): Breccia Zones
