Mark, in addition, this issue was discussed at length a while back with Kim as the moderator. He explained that within what the industry calls "standard fire assay" a variety of fluxes, a variety of extraction metals (correct my terminology please) etc..are all included under the "standard" heading. All this results in possible combinations in the hundreds all under the heading of SFA. In other words, the industry accepts these groups of materials under the "standard" heading and if you use any of these in some combination, you are within the SFA category. It's like saying a Ferrari isn't a car because it doesn't look or perform like a Taurus. Well if you start with a common criteria for a car, then there isn't any discussion and you all understand that as long as it has four wheels, passenger seating, an internal combustion engine and internal direction and speed controls, then you can agree they are both cars designed to meet two very different performance criteria. So technically Bill is correct but he is playing a semantics game here. There NEVER is one standard method of SFA since every ore body is unique to one degree or another. Mark, as you said, let's trust CPM's assesment since they are certainly considered the current experts on PM's and where this industry is going and why. For years all the big names have steered clear of Naxos while we fiddled away with dozens of assay methods. Now with SFA, suddenly (in a relative sense) we have one of the preeminant names in the metals market on board, retained to help Naxos move to the next stage. I think that puts a very large stamp of approval on WHAT and HOW we are testing at FL. And that infers approval of our particular version of SFA testing as repeatable, reliable indication of what is in the ore. Regards, Tom F.
