ChanTuk Copper prospect is only one of several copper prospects which landmark a narrow 11 km long NS oriented strip which general trend is aberrant if compared to the strike of the regional sedimentary formations.
Chan Tuk copper prospect was studied by means of underground working at level -9 m, and 4 inclined drilling holes which investigated its roots between -50 and -80 m. It is located on a vertical narrow strip of ungranitised sediments in the position of a roof-pendant in an albite granite batholith of regional extension. This strip is sheet-like thin if its three dimensions are being compared: it is some 570 m long, 100 m deep, and only 708 m wide. Being a tectonical zone of weakness it has been the location of shearing movements and of an intrusion of potash pneumatolithic origin which brought along some copper mineralization.
Near the surface this mineralization is gathered into four shoots but at depth it has an equal repartition in two main vertical zones found in continuity along some 300 m. Along this distance the measured reserves are 1,400 metric tones of Cu metal scattered in 26,000 m3 (some 70,000 T) of ore with a general 2% Cu content.
