Vancouver — Diamond drilling has uncovered three types of mineralization on
In the past, the 30-sq.-km property was explored and mined for copper-oxide skarn and copper-molybdenum-gold porphyry mineralization. The recent drilling by Tyler has turned up high grades in the skarn/breccia mineralization and in the main porphyry zone.
Hole 14, which ended in a mineralized porphyry unit, returned 18 metres grading 1.2% copper and 0.35% zinc, plus 0.13 gram gold and 13 grams silver per tonne.
This intercept occurred in an interval of 105 metres grading 0.42% copper and 0.16% zinc starting at a down-hole depth of 120 metres.
Holes 14 ended in mineralization, owing to difficult ground conditions, as did hole 13, and hole 15 intersected 31.6 metres of a skarn breccia, after which bad ground conditions forced drilling to cease. Hole 16 is under way.
Tyler believes the high-grade nature of the unoxidized porphyry unit in which the drilling ended is significant. Starting at a down-hole depth of 216 metres, the hole intersected 9.15 metres grading 0.37% copper and 0.32% moly, plus lead, zinc, gold and silver credits.
The porphyry complex has a strike length of more than 4 km.
Tyler is eyeing Bahuerachi for its bulk-mining potential.
