1/ Goldboro! Part 1 of #NewtonInterviews The Unknown Geologist on the geological model for this exciting gold project in Nova Scotia, Canada owned by @Anaconda_Mining: ceo.ca/@Newton/findin…
2/ Quotes from the Unknown Geologist to follow... "I know the Boston Richardson model very well."
3/ I remember reviewing a diagram of the Boston Richardson belt that shows the historic mining, and it highlights the top and bottom of an ore shoot on both limbs.
4/ If you use the Boston Richardson as a model for what the other belts should look like, then there's no reason why each one of them shouldn't have a high-grade concentration somewhere, probably due to a secondary flexure on the main anticline.
5/ That type of structural control can create dilation zones, which are the areas where the really good stuff gets concentrated. If you flex the rock in a certain way, then you'll get more of a concentration of liquid in certain areas than others.
6/ All this affects how you approach exploration drilling. What Osisko did was a perfect example: they went out there and drilled every 25 meters on the north and south side of the anticline because gold occurs on both limbs.
7/ They drilled a hole and they'd get three or four intersections of really nice stuff, which is like 6 grams or better based on what I used to see at Forest Hill.
8/ When you have so many belts to drill through, you can hit this stuff in many different places and Osisko was trying to tie it all together into a massive open pit model, but ...
9/ no one has ever said, "There are 6+ grams in that one belt here – let’s see if that continues up and down dip by drilling 25 meters east or west of that 6+ intersection."
10/ Anaconda now knows about quite a few of these high-grade intersections with hundreds, if not thousands, of grams per tonne. I saw those at Forest Hill, too – not many of them, but a few.
11/ And every single time that we had a thousand grams per tonne, we were in the middle of the ore shoot. Even when we were in the hundreds of grams per tonne, we were in an ore shoot.
12/ I think Anaconda should start with all those thousand and hundreds of grams per tonne intersections. Just start looking there and do their infill drilling up and down dip based on those known high-grade intersections. There are so many belts that they could look at and...
13/ ...each one will have an ore shoot or two, so you could quickly get overwhelmed by the number of targets out there. What a GREAT problem to have!
