- Abstract
The Ming Mine is located approximately 13 km east of Baie Verte, Newfoundland and is one of the Consolidated Rambler Mines deposits. It operated from 1972 to 1982 and produced 2.1 Mt grading 3.5% Cu and 2.5 g/t Au. Production was halted due to declining metal prices and because mining operations reached the property boundary. The Ming Mine consists of volcanogenic massive sulphide ore with mafic-volcanic dominated hanging wall and felsic- dominated footwall. The Ming Massive Sulphide is composed of several moderately northeast-plunging, elongate lenses including the Ming South Zone, the Ming North Zone, the 1807 Zone and the Ming West Zone. Hanging wall mafic rocks consist of intercalated mafic flows, mafic intrusive rocks and minor turbidic sedimentary rocks. The felsic-dominated footwall consists of chlorite and sericite altered felsic volcanic rocks cut by abundant massive mafic intrusive rocks. A broad zone of copper mineralization occurs within the footwall known as the Ming Footwall Zone (MFZ). The MFZ consists of stringer chalcopyrite and pyrrhotite which is associated with strong chlorite and lesser sericite alteration. The temporal relationship between MFZ to the Ming massive sulphide zone is contentious. Deep directional diamond drilling exploration is ongoing to assess the downplunge extent of the various massive sulphide zones and to evaluate the extent of the Ming Footwall Zone. Mine rehabilitation including mine dewatering is underway and underground delineation drilling commenced in Fall 2007.
