Jim,
I see, for over a year now since I last posted this, no one has noticed the similarity in the layout of the BMG Kori Kollo find and what Guido had found. Now BD has confirmed the difficulty in assessing the GE find and didn't Guido mention more core samples wouldn't help assess this find.
...hhmmmmm, Guido is right after all? NAAWWWWW, couldn't be, his report was discredited, wasn't it?

Commercial production from the milling facility at the Kori Kollo mine commenced in February 1993, at which time heap leaching of oxide ore was discontinued. The cost of constructing the milling facility was partially project financed.
Gold production attributable to BMG in 1998 was 295,000 ounces.
The total cost of the property and its associated plant and equipment is $344.3 million with a net book value of $70 million at December 31, 1998.
The project is in the Andean tectonic belt of western Bolivia between the Cordillera Occidental and the Cordillera Real, and within an area of lacustrine deposits on the altiplano. Deformed Paleozoic sediments and a Tertiary volcanic sequence underlie the lacustrine deposits. Locally these rocks form topographic highs, reflecting block-faulting. Irregular masses of biotite-hornblende dacite porphyry intrude the Paleozoic sediments. The deposit is contained within two varieties of dacite porphyry intrusions. Both varieties of dacite have been pervasively quartz-sericite altered throughout the deposit. The most important structural controls of mineralization are fault systems which trend in two directions and contain auriferous sulfide veins and veinlets. Some veins contain minor stibnite, tetrahedrite, galena, sphalerite and realgar.
Inti Raymi utilizes conventional open pit mining methods at Kori Kollo. Ore from the Kori Kollo mine is processed at the mill in a cyanide carbon-in-leach circuit. The mill processes an average of approximately 21,000 tons of ore per day. The Kori Kollo operations are subject to Bolivian environmental laws and regulations. |
