Hole 201, the first 40-metre stepout hole to test for depth extension of mineralization at the B zone, cut 37 metres grading 2.6% copper plus 0.28 gram gold and 16.8 grams silver per tonne. It undercut a hole sunk in 2001, which returned 5.2% copper across 29.6 metres.
Ongoing drilling indicates that the B zone continues at depth. At last count, the zone’s resource stood at 3.2 million tonnes running 5% copper, 1.1% zinc, 2.3 grams gold and 18.2 grams silver. The zone remains open at depth and along strike to the south.
A second drill rig is testing for downdip and strike extensions on the D zone.
Hole 202, the first 75-to-100-metre stepout hole on the D zone, has extended mineralization at depth at the northern end of the deposit, cutting 28.3 metres running 2.4% copper, 6.6% zinc, 0.36 gram gold and 34.7 grams silver in the main massive sulphide lens. Below that, a 15-metre section from the footwall stringer zone yielded 2.3% copper, 2.1% zinc, 0.15 gram gold and 21.3 grams silver.
The hole undercut some older holes which had returned up to 2.6% copper and 7.5% zinc over 18.3 metres.
The D zone hosts a drill-indicated resource of 1.6 million tonnes running 2.1% copper, 4.9% zinc, 0.6 gram gold and 59.1 grams silver.
Varying widths of massive and semi-massive sulphides have been cut in holes 203-205, 207 and 208. Hole 206 failed to cut the hangingwall diorite on the western side of the deposits.
Drilling this summer will also test other targets, including the G zone, where grab samples have returned copper values exceeding 6%.
The High Lake deposit is one of the highest-grade undeveloped polymetallic deposits in Canada, with resources totalling 5.3 million tonnes of 4.05% copper, 2.4% zinc, 1.76 grams gold and 31.7 grams silver. Most of the resource is amenable to open-pit mining.
Earlier this year, Wolfden acquired a 6.8-sq.-km adjoining property covering the western extension of the Granite Lake magnetic anomaly, a possible kimberlite target.
