Everyone has probably ran the same numbers on their own in some form or fashion. With no real numbers this is what I can offer

All this info comes from this page:
http://www.brazil-minerals.com/ownership-positions/mineracao-duas-barras-ltda/

Per PR they are operating in Jequitinhonha River valley. MDB has two mineral rights in that area, one is the 982 acre they are expecting govt approval on soon so I assume they are not there, the other is the 422 acre area which I believe had NI 43-101 technical report in 2007 and updated 2008, that report stated average:

0.16 carats of diamonds per cubic meter and 182 milligrams of gold per cubic meter

OK large permanent plant can run 45 tons / hour, so they said the D/GRU can do about .25 of that, so 11.25 tons per hour.

Estimating material is about 2.4 tons per m3, so they can run about 4.7 m3 material per hour.

Using the NI43-101 numbers:

Plant operation, Diamonds / Gold

8 hours, 6.02 carats / 6.88 g
16 hours, 12.04 c / 13.76 g
24 hours, 18.06 c / 20.64 g

Of course there is some eff % with extraction and costs..

If this is where they are - pretty good diamonds, not so much gold. Diamonds are good too!!

So just trying to entertain myself until we see some real gold and more carrots...
