Hello Bill, I also disagree. Mining at Luicho will be difficult. Look at the photo on Southwestern's website. Where will they put the leach pads? How long will the ore haul be? When you are playing with one gram material (recoverable), you can't haul very far and make money.

The Yanacocha mine cash costs are about $120 per ounce. The infrastucture is excellent. Not at Luicho.

"If it is all easily fractured and leachable from surface a fairly low cost operation will ensue. with 4.5 grams per cubic meter and 90% recovery we have a value of about $35 per cubic meter. They describe it as intensely fractured? that means it can be ripped and graded and hauled by draglines(low cost dragged buckets) and conveyors, given a minimal crush and size with low energy that should cost less than $12-13 per cubic meter, leaving $22-23 as the yield in profit" what, If you have recovery problems from preg robbers (carbon) the last thing you want to use is equipment that does not allow any selectivity while mining. You end up mixing the leachable and not leachable ores and reducing your gold recovery or as a worst case ruining your heap leach pads. Brewery Creek, in the Yukon, had a problem with carbon preg robbers and it reduced their minable reserves considerably.

Sorry Bill, cash costs and cap expenditures will be high here, it's not as rosy as management says. Maybe the majors who also looked the property before PFG saw the same stuff.

Any comments?

Cheers
