Black Hawk drilling adds to Hoyle Twp. property resource

Results from four drill holes have expanded the mineralized zone at the Hoyle Twp. property of Black Hawk Mining (TSE).

The recent work brings total drilling on the property to 5,278 metres and extends the strike length of the mineralized body to 300 from 250 metres. (Previous results had suggested the zones extend to a depth of 200 metres.) All four known mineralized zones were intersected in the latest phase of drilling, and there are indications of gold mineralization on the contact between the volcanic host rocks and an ultramafic unit to the north.

The V-1 mineralized zone was intersected in both infill and extension drilling over core lengths from 1.25 to 6.5 metres. Grades ranged from 1.5 to 11.81 grams gold per tonne.

In drill hole 23, on the eastern end of the zone, indications are that the V-1 structure splits into northern and southern subzones. V-1 North was intersected over 4 metres grading 9.92 grams per tonne, which included 0.85 metre grading 39.47 grams. V-1 South averaged 11.81 grams over 6.5 metres, including an interval of 3.5 metres with 20.43 grams, which, in turn, contained shorter lengths grading as high as 54 grams per tonne.

The V-2 zone was picked up in two of the four new holes, grading 0.89 gram gold per tonne over 0.5 metre and 2.67 grams over 1.5 metres. V-3 was intersected in the infill drilling with a core length of 1.5 metres and a grade of 4.5 grams per tonne.

The V-4 zone is still in evidence as exploration moves eastward. In one hole, a core length of 10 metres averaging 6.05 grams per tonne includes a 2.7-metre interval grading 11.86 grams and a 3-metre interval grading 8.64 grams. Both these intervals contain sections with grades exceeding 20 grams.

So far, 17 of Black Hawk’s 24 drill holes on the property have contained some visible gold. The company plans to work eastward to test possible strike extensions of the mineralization.
