The Nymagee deposit being Cu-rich and the Hera deposit, located ~5km southeast of the Nymagee deposit being Pb-, Zn- and Au-rich. This metal zonation between the two deposits is thought to be related to temperature gradients of the mineralising hydrothermal fluids that were focussed along the shear zone that connects the two deposits.

Massive Sulfide

 · Massive Sulfide Massive sulphides have densities ranging up to 4240kg m−3, and within host rocks of densities around 2750kg m−3, a sulphide body having a width of 50m, a strike length of 500m, and a depth extent of 300m would give a gravity anomaly of about

Crandon Zn

Exxon''s 1986 estimate was 42.9 million tons at 8.4% Zn, 0.60% Cu, 0.73% Pb, 1.80 oz/ton Ag, and 0.05 oz/ton Au. DeMatties describes the mineralization as sphalerite, galena, and chalcopyrite in syngenetic laminated and thinly bedded pyrite, interbedded pyritic and carbonaceous meta-argillites, pyritic metatuffs, metacherts, and dolomite.

The Geochemistry, Distribution and Mobility of Metals …

Mining activities at the abandoned Mount Bulga Cu-Pb-Zn-Ag deposit resulted in large amounts of previously buried sulfides being brought to the surface causing the potential of acid mine drainage to be a problem or concern. The pH values measured in the surface soils range from strongly acidic to neutral (3.6-7.9) but averaging mildly acidic (5.2). The distribution of metals in the soils show ...
