RE: RE: Greetings Vested Interest
RE: RE: Greetings Vested Interest Bloomfield, the key point of my response to your inquiries is that at this point we have no basis to suggest that drilling into a narrow strike vein etc. can only indicate high grade mineralization within the high grade intercept. Quite the opposite.
An example of this would be Giroux's observation that “orthogonal veins have historically been the most abundant and highest grade in the camp, representing greater than 60% of the ore from the No. 1 mine “ and yet were “usually less than 1 ft. wide”.
So, if BGM were to have drilled into an orthogonal vein (or other) and recorded X g/t over a small intercept this does not in itself suggest that there is only one small vein with high grade ore surrounded by waste rock. In the historic mining we see that all of the ore in a much larger ellipse, and of substantially greater depth (and stopes themselves were elliptical in plan and of substantial depth) was high grade ore. Hence the consistency of 0.35- 0.6 oz/ton in the historic mine production. I use this as an example of something we cannot yet infer from certain high grade intercepts. The vein stockworks yielded high grade ore over much greater widths and depths despite the fact that a certain vein may only have been intercepted over a narrow width. For this clarification I await the geological model as Peter George shall present it, and I am especially interested to see an updated 3D model in this regard. And this observation only concerns the quartz vein structures that exist. The highest grade ore zones were and are the deeper elevation replacement ore zones which have been discovered and are yet to be interpreted in the report.
