Dr. Webb Sharpens His Blanking Point...
I asked Dr. Webb to clarify what he said earlier this year when he mentioned that one in three early Con Mine drill results came up blank when they were targeted for ore bodies.
Here's the clarification he sent me last night. Thanks Dave.
Cheers, Baires
I had told you earlier, that my experience at the Con Mine (Yellowknife), at the Ptarmigan Mine (east of Yellowknife), and reviewing the records at the Discovery Mine (Past producer at the Yellowknife Gold Project), show us that on average, one out of every three drillholes (approximately) within an orebody (or stope) report insignificant or intercepts that are well below ore-grade. Likewise, when I was working as a production geologist, it was not unusual to get similar results during production sampling.
