Mr. Wendell,

I have been lurking and appreciating you comments from the start of this thread. You said:
"The dilution effect will be 115Ft of low grade will
get mixed up with 200 Ft of high grade. The dredge will run at 7,000 to 10,000 tons
per hour, if it is that big. It will take a big one to get that deep. It is an attractive
proposition if the process can keep up with the production.If they think they have
that thickness in high grade (200Ft), they better forget what I said about proving
their assays and delineating the reserve. The risk is too great to do otherwise."

Naxos has obtained precious metal assay results by high temperature fire assay (albeit from non-COC samples) using a prior technique to Johnson/Lett from surface to 150' on two or three holes, and on one deep hole in Feb./96 down to 510'. Even at that depth there was no evidence that values were falling off. The Behre Dolbear COC drilling is supposed to be a series of 15 holes, each to a depth of between 250' and 500'. A further 190 holes are planned.

If these results confirm a more or less uniform distribution of high levels of PMs from surface to 500 or more feet, are you saying that there would likely be a limit beyond which dredging could not be carried on, or at least would no longer be economical? If so, what would limit it?

It is very thoughtful of you to take so much time on this thread. It just seems that the more you post, the more questions appear!

Many thanks and only the best in '98.

Lawrence
