<<1. Drill hole TG-1 intercept over interval 26.0 to 30.9 meters should read true width 4.9 m at 150.7 g/t Ag, not 12.0 m true width. This correction may slightly affect the average grade calculated for the deposit. >>

Good observation Amit...

But i think that the error does not affect the total width and garde of the hole... it is only a typo on the true width of the last section

manhattan-min.com

<<2. I don't understand how the average of TG-11 can be 628.9 g/t over 13.8 m, when 10.7 m of that interval show an average around 25 g/t. Are there nuggets in the samples? If so how will that affect continuity calculations? >>

Good catch again... either the 628g/t is a typo or the section below and above the 5.6m has it a rich pocket in the 1300g/t Ag... which is a possibility. I'll try to find an answer.

<< How did these assays compare to the BRGM assays with respect to Ag values (which I believe are the only overlapping elements in the assays)? >>

IMO, these are not overlapping elements. My understading is that the overlying oxidized cap was not assayed by BGRM... so the silver in there is new silver. Remember that in 1979-80, there was no such thing as heap leaching... companies where simply not looking for this stuff..they were after the sulfides. But again, I could be wrong... will check as well.

In any case, the silver grades on the sulfide body are 38g/t ton.
