Hello Frank! (Tanoose;>) Now I see why 82 has bought 3.5 million shares in 10 days. NEM has sent a large technical crew down to assist ARP in where to go from here...so far not too many problems...still I believe that there could be a correction, then it will be buying time again. Anyone who has followed 82 on their strong buying days could have made good money trading this.

Good luck to all !

This must be very interesting results if we have a bulk production here. Liberate me from two things: Now it seems that the silver values is a big part of the gold equivalent, do we still have problems with the associated minerals? What about the cost for bringing the 100 m overburden away? 1g Au? Somebody?
Theses two questions is not new for this deposit and of course is the results excellent compared to the earlier ones.

Regards,
Gunnar

Frank, the 100 grams per ton average of silver equal about 1.5 grams per ton gold equivalent with silver at $5 and gold at $300( 60:1) added to the 2.3 average gives you a total gold equivalent of 3.8 grams per ton. Assume leach efficiency of 85% this gives you 3.25 (about .1 ounce or $30 worth)grams per ton. A cubic yard has 2.7 tons and sol you will recover 8.75 grams per cubic yard(about $80 per cubic yard)
The total cost of mining, crushing to leach size and leaching depend greatly on the depth you must go and the hardness/toughness (grinding index) of the rock and the amount you recover on leach depends of the rock/gold/silver chemical organization in the rock, does it have sulfides? arsenic? etc.

The best case is rock is heavily weathered on surface and has no sulfides and it will crush easily and leach fast and can be ripped up by claw dozers and this will give a total cost of under $10 per cubic yard for mine leach etc. Worst case is deep hard sulfided rock which can cost you $40-50 per cubic yard.

From their web site it seems to be about 120 million tons and expanding at about .1 ounce total silver and gold per ton indicates it could be 12 million ounces or more(as they expand) and it seems to be about 100 meters deep where values start. This is a rough calculation but it seems to me that this will become a major mine, and they are still gathering data. There is nothing on the site about rock hardness or rock metallurgy, but Newmont is as eager as a young puppy and there will no doubt be some kind of bidding war here later on???
