re: Ann: TRF: Explains High Grade Exploration...
OK. I replied to OO after a lot of the local jungle juice last night and it looks like his pessimism swayed my response a bit, probably justly so.
With regard to the orientation, it is possible they drilled down a steeply dipping fault which sits "perpendicular" to the more flat lying strataform structures which are said to host the gold. That said, if I'm reading them correctly, the company is running with a carbonate replacement story for the silver at this stage as opposed to fracture filling. They haven't retracted from their view that the "carbonate horizon" is pervasively altered, despite the second hole coming back barren. The other 8/21 holes will decide that matter.
We do know that the horizon is deeply weathered, at least for the upper holes. If I recall correctly there was something written along the lines of red mushy stuff with a fair bit of core loss, making the smear and contamination issue well worth considering.
There are two things that perhaps throw a bit of a problem into the theory of "a nugget effect due to a (possibly quite small) patch of native silver within the fault zone, with all the smearing and down-hole contamination that can produce." And that is the metal ratios, and their distribution throughout the intersect. It appears that the silver and copper cohabit, with two distinct peaks in concentration some 10m apart. While the Tungsten is somewhat more uniform in its distribution. Furthermore, one may expect contamination to be favoured downhole but the numbers in the head and tail of the intersect don't suggest redistribution with bias in any direction. So, I'm yet to be convinced that the native silver nugget theory is what's going on there OO. Thoughts?
