It was a remarkable gold intercept from an already remarkable gold-silver deposit. This morning Pretium Resources (TSX, NSYE: PVG) said it hit a record gold intercept at the Brucejack project in BC, Canada, with as much as 41,582 g/t (1,337 oz/t) gold over a half-metre within a broader, uncapped intercept of 3 metres @ 8,330 g/t Au and 5,628 g/t silver.
The new record dislodges Pretium's former top intercept by a wide margin - double in fact. Just over a year ago Pretium reported up to 18,755 g/t Au over 0.6 metre in a drillhole that was started, at surface, about 169 metres away from the new record-holding drillhole.
Now, as some exploration eye candy, the top three reigning high-grade intercepts at Brucejack are:
1. 41,582 g/t Au over half a metre - July 2012
2. 18,755 g/t Au over 0.6 metre - May 2011
3. 17,750 g/t Au over half a metre - October 2011
The list is, more than anything else, emblematic. Brucejack is one of the more sizeable high-grade gold projects out there in the hands of a junior explorer, or major for that matter. If not all intercepts assay in the realm of kilograms gold per tonne, as above, there are nonetheless scores of multi-metre intercepts with gold grades in the dozens to hundreds grams-per-tonne range.
On the whole these have allowed Pretium to show high grades at Brucejack are not just a matter of handful of outliers in a sea of average intercepts, but a matter of high-grade gold with serious legs. Pretium flexed that muscle in April this year when, in a hefty resource update, it outlined 4.9 million ounces gold @ 17. 3 g/t in indicated resources and 10.4 million ounces gold @ 25.5 g/t in inferred resources (combined there was also about nine million ounces silver grading between about 11 to 15 g/t Ag in resources). |
