Toronto-based Kirkland Lake Gold can't seem to miss drilling high grades at its Macassa gold project in the town of Kirkland Lake. Recent excellent results highlight the potential for growing resources and new discoveries, says the company.
Drilling east of the South Mine Complex (SMC) has returned 118.8 g/t gold over 2.0-metres core length, 62.7 g/t over 1.9-metre true width, and 73.8 g/t over 2.7-metres true width.
Drilling 250 metres west of the current SMC resources returned 4,772.2 g/t gold over 2.0-metres core length, a pair of 436.9 g/t over 2.8-metres core lengths in separate zones, and 158.0 g/t over 2.4-metres true width.
Drilling also expanded the Lower SMC to the east and at depth, returning 2,458.6 g/t gold over 1.8-metres true width, 523.2 g/t over 2.0-metres core length, and 20.0 g/t over 3.8-metres true width.
At the amalgamated break, new drilling to the east returned true widths of 429.1 g/t gold over 2.7 metres, 164.8 g/t over 2.1 metres, and 26.7 g/t over 1.2 metre. KLGold geologists also reinterpreted historic holes to the west and relogged core lengths of 827.9 g/t gold over 2.0 metres, 360.9 g/t over 2.0 metres, and 333.8 g/t over 2.0 metres.
Kirkland Lake says the amalgamated break has substantial exploration potential largely untested by historic drilling. A previously unidentified area of bonanza grades was recently drilled from the 5700 level ramp development. The reinterpretation of old cores from the break resulted in the identification of a new steep north-dipping zone north of - and likely associated with - the amalgamated break.
