To All:

Long time lurker... up periscope... open napkin...

From previous GPGI releases 5 tons of enhanced ore, milled and
leached yields 1000 lbs. of primary concentrate ( this is the stuff
that needs to dry ) further yields 800 lbs. of dore metal.

"Assume" GPGI's enhanced ore has 7 oz. of good stuff per ton.
Further assuming that GPGI's leaching process recovers 100% of the
precious metals in the enhanced ore then 800 lbs. of dore metal will
contain 35 oz. of precious metals.

If AuRIC can process 3000 to 4000 lbs of dore metal a month, best case
this would yield:

4000 lbs dore metal / 800 lbs. * 35 oz. = 175 oz. of good stuff.
and 175 oz * $300/oz = $52,500 / month.

There are lots of very optimistic assumptions here which offend my
engineering sensibilities so..

I'm going to assume GPGI's leach to dore metal process only recovers
50% of the precious metals content of the enhanced head ore. Also
assume that AuRIC can process only 3000 lbs. of dore metal per
month so...

3000 lbs dore metal / 800 lbs * (35 oz * .5 ) = 65.625 oz of goodies
and * $300/oz yields $19,687.5 per month.

All in all still very good news. Especially if the process yields
itself to easy ramping. I note that a past post or news release
indicated that GPGI was installing two more furnaces. So I would
expect the bottleneck will still be at AuRIC.
