Goldcorp defines new shoots at Red Lake mine property

Exploration at the Red Lake mine of Goldcorp (G-T has defined several pipe-shaped structures in known high-grade zones and may have identified new mineralization near the mine’s western boundary.

Thirty-five delineation drill holes sunk in high-grade mineralization at deep levels of the mine have revealed that much of the highest-grade material lies in compact ore shoots. Those shoots form plunging structures in previously defined tabular zones. Ten drill holes intersected one pipe, the Main zone, over a vertical length of 70 metres. An elliptical cross-section of the pipe measures 12 by 60 metres. On average, the pipe grades 163 grams gold per tonne over 10.6 metres.

Drilling has also identified three other pipes, one in each of the Footwall, Hangingwall, and Hangingwall 5 zones. Each of those pipes is defined by four or five drill holes, and grade between 33 to 144 grams over intervals of 10.9 to 12 metres.

Goldcorp continues to find mineralization outside the pipe structures. The company has intersected grades of up to 144 grams (over a core length of 6.3 metres) in the Footwall and Main zones, and up to 598 grams in a narrow part of the Hangingwall 5 zone. The company also intersected the zones below depths of 1,524 metres, with grades ranging from 2.4 to 266 grams over widths of 1 to 3 metres.

Drilling from the 1,338-metre-deep 30 Level intersected 5.4 metres of quartz-carbonate mineralization grading 13.7 grams. That intersection was pulled from an area near the western boundary of the mine, which is adjacent to the Campbell mine of Placer Dome (PDG-T). That zone may be related to an intersection recovered from 24 metres above, and could indicate a western-plunging structure.

Three holes drilled from the 17 Level, which lies 759 metres below surface, intersected sulphide mineralization with gold grades of 7.2 to 24.3 grams over intervals of 2 to 4.3 metres. The results are believed to indicate that previously discovered structures extend to depths of 580 to 759 metres.
