Abstract. The lead-zinc ores occur in a shear zone in Precambrian metasediments. The shear zone is later than the two recognized generations of folds, and contemporaneous with wall-rock alteration and subsequent mineralization. Flow directions of mineralizing solutions are deduced from the mineral zoning pattern; galena follows sphalerite ...

Sullivan, British Columbia, Canada. Discovered over 100 years ago, the Sullivan deposit was the largest SEDEX deposit in Canada, producing 116 million tonnes of zinc (5.8 % Zn) and lead (6.7 % Pb). The mine is no longer producing but Santa Fe Metals and Eagle Plains Resources are pursuing SEDEX prospects in the area.

The zinc ore mined is processed through crushing, and milling operations, being sent for aeration and flotation procedures, and eventually to the concentrator for zinc concentrate production. The Gamsberg mine has a reserve and resource of more than 180Mt, an average grade of between 6 and 6.5%, and an estimated life of mine of 20+ years.
