Stepout drilling along the Zone 3 vein at the Prairie Creek property, 500 km west of Yellowknife, N.W.T., is intersecting high-grade silver-lead-zinc mineralization.
With four holes drilled to date, San Andreas Resources (TSE) has extended the vein deposit 630 metres northward to a strike length of 1,480 metres. The company began its program by redrilling hole 94-90 to a greater depth, whereupon it intercepted 6.4 metres grading 13.6% zinc, 0.8% copper and 12.6% lead, as well as 289.7 grams silver per tonne at a depth of 431.4 to 437.8 metres. The intersection is 40 metres north of any previous Zone 3 drilling.
A stepout hole, 172 metres along strike from hole 94-90, returned 5.2 metres of 11.8% zinc, 13% lead and 0.3% copper, as well as 198.1 grams silver per tonne, for hole 95-95 at a depth of 417.9-423.1 metres. Follow-up hole 95-99 stepped-out a further 214 metres to the north and yielded 1.9 metres of 3.5% zinc, 3.4% lead, 0.2% copper, and 1.7 grams silver per tonne, at a depth of 732-733.9 metres.
Hole 95-109 extended the deposit a further 206 metres north by returning 3.9 metres of 22.9% zinc, 20.4% lead and 0.5% copper, as well as 244 grams silver per tonne, at a depth of 602-605.9 metres.
San Andreas continues to step out on the vein and is now drilling 200 metres north of hole 95-109.
At the end of 1994, geological resources on the property were calculated at 6.2 million tonnes grading 12.9% zinc and 12.2% lead, plus 180 grams silver per tonne. Of this, 4 million tonnes averaging 12% zinc, 14.3% lead, 0.4% copper and 218.2 grams silver per tonne are contained in Zone 3 along a strike length of 850 metres. The zone contains two main levels of underground workings, immediately adjacent to a mine site and existing
1,100-tonne-per-day mill.
The Prairie Creek project was initially developed as a silver mine in the early 1980s, but, owing to financing difficulties, it never reached production.
The property is 27 km long and encompasses more than 110 sq. km. A second drill rig is testing for stratiform mineralization near the southern end of Zone 3. Hole 95-97 intersected half a metre of 9.9% zinc, 3.4% lead and 34.6 grams silver, while hole 95-103 returned 2 metres of 29.2% zinc, 12.7% lead, 0.1% copper and 2.2 grams silver.
