At that time, the deposit reported a remaining historical (non NI 43-101 compliant) resource of approximately 1 million tonnes grading 0.4% Cu, 6.4% Zn and 1.3% Pb.  The mineralized zone is open to depth and along strike.The two major mineralized zones are from 5 to 10 kilometers-long, up to 30 meters thick and enveloped by thick brecciated and altered zones.  Large lenses of replacement mineralization branch out into the evaporitic limestone of the Triassic Calcare Cavernosa formation.  Coltstar plans to carry out a program of data compilation, geochemistry, geophysics ...
