Exploration History and Mineral Potential of the Central

The Polaris deposit was a carbonatehosted, Mississippi Valley–type ZnPb deposit of about 20 million tonnes grading about 17% Zn + Pb. The mined ore body was 300 m wide by 800 m long by 20 to 150 m thick and consisted of sphalerite and galena, along with the gangue minerals pyrite, dolomite, and calcite (Savard et al., 2000).

Sedimentary exhalative deposits Wikipedia

Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of orebearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.. SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten
