Comparison of Peruvian Gold Head Grades.So I found out the head grade for the Yanacoha property
FY2009 has been a good year for Minera Yanacocha. Gold productionreached2.06 MM oz while silver production reported 3.8 MM oz,representing a13.7% increase in gold and a 7.9% rise in total silverproduction. Theseencouraging results were largely due to higher goldgrades and areduction in the waste-to-ore ratio, corollary to thechange of mine plandesigned to reduce the tonnage mined fromChaquicocha and stepping upthe ore tonnage extracted from La Quinua andYanacocha. The gold millthroughput exceeded all expectations in 2009.It processed5’660,708 DMT with an average grade of processed ore of0.93 g/t Au and2.94 g/t Ag with recoveries of 85.4% for gold and 67.4%for silver. Yanacochareported sales of US$ 2,013 million, US$ 727million net profit and US$982 million cash from operations. Yanacochacontinues to work towardsstarting up the Conga project, a copper-goldporphyry project. Given thatit is located east of its currentoperations, Conga could sharefacilities with other similar projects inthe region. Oxide ore reserveson the other hand, dropped from 13.01 to10.53 million ounces of gold asof year end 2009. This reductionoccurred primarily at Yanacocha (1.49million ounces) and at La Quinua(1.29 million ounces).

I was reading over the SUE presentation [1]:
Indicated Resource is
1.9M oz @ .50 g/t
That'sa very low head grade. I'm not a gold expert. But I assume the pitswould have to be very shallow tomake this project economical. And Iwonder how high the operating costwill be.

Gold grades are improving!
So given the regional head grade, LPK will likely define an economical gold resource. And They have 10 more area targets to drill (A2-A11)
