Ozinca Peru SAC a 100 owned subsidiary of Oakdale Resources has acquired the Chimu Gold plant in Southern Peru. nbsp nbsp
The Chimu Gold plant is a gold lixiviation plant that is strategically located to purchase high grade gold ore from a significant number of existing small gold miners in the Ayacucho and Chala region of Southern Peru.
The last ten years of continuously increasing gold price has resulted in a boom of small mining activity focused on the extraction of the abundant narrow, high grade veins found in this region of Peru.
As a result of the increase of this particular class of ore production, Oakdalenbspwill toll process the ore supplied to its Chimu plant with a Carbon in Pulp CIP process, this carbon will then be transported to Lima for final Gold processing and the gold bullion will be sold to overseas buyers.
In addition, the company plans to develop its own mining operation relatively close to the plant to provide a constant source of ore which over time should completely remove the need to purchase ore. nbsp
Oakdale will also identify and further develop Gold plants in other Gold districts of Peru. nbsp nbsp
The company has the vision to become one of the top ten producers and exporters of gold in Peru by 2020 through development and operation of small high-grade underground mines to supply ore to its efficient state of the art gold processing plant in the gold districts of Peru. nbsp nbsp

Some 45km from Cajamarca in northern Peru, at an altitude of 4,700m, Minera Yanacocha operates a complex of four gold mines and a processing facility. This was the first significant foreign investment in Peruvian mining for 20 years. The mine is located in the Peruvian Andes at an elevation of 14,000ft above sea level.
A haul truck, part of the Minera Yanacocha fleet. The ore is transported 2.5km or more to the leach pads by the German contracting company Ed Zublin, using wheeled loaders and 85t-capacity trucks, and is heaped by stackers.
Since the Carachugo ore is porous, run-of-mine ore can be heap-leached without crushing. The initial heap was cyanide leached at a rate of 10 litreshmltSUPgt2ltSUPgt into a 16,000mltSUPgt3ltSUPgt pond and the solution treated in a Merrill Crowe plant.
Some 45km from Cajamarca in northern Peru, at an altitude of 4,700m, Minera Yanacocha operates a complex of five gold mines and two processing facilities. Not only was this the first significant foreign investment in Peruvian mining for 20 years, but the project was undertaken in an area where guerillas were active, so the operation had to be heavily protected without antagonising local residents.
The first gold was poured in August 1993 and by 1996 Yanacocha was producing over 800,000ozy. Subsequent investment and improved operating practices enabled the company to raise sales progressively to a record 3.04Moz in 2004, followed by a further hike to 3.3Moz in 2005. However, during 2004 Minera Yanacocha responded to growing local concern about the intensity of development by relinquishing its exploration permit for the Cerro Quilish deposit.
The Yanacocha gold district is a 10x4km zone of altered rocks within a belt of tertiary volcanics that extends the whole length of Peru. Andesitic domes and dome complexes have been silicified and leached by epithermal gold-bearing solutions in at least nine distinct deposits. The mineralised sequences, which can also contain significant amounts of silver, are flanked by extensive argillitic alteration, and subsequent events have created siliceous breccia pipes with localised high gold grades.
Year-on-year, Minera Yanacocha has usually been able to extend its oxide ore reserves faster than ore is being mined. By the end of 1998, proven and probable reserves had grown to 20.1Moz of gold and peaked at 36.6Moz by end-2000 plus 350Moz of silver. By end-2005, the project had a proven and probable reserve of 1,142Mt grading 0.9gt gold, for a total gold content of 32.6Moz.
Yanacocha produces ore from two open pits and is reclaiming three. First production came from the Carachugo pit, followed by Maqui Maqui in 1994 and the San Jos Sur pit during1996. Cerro Yanacocha, opened in 1997, and La Quinua, where production started during 2001, provide the current production.
Drilling, using Ingersoll-Rand DM45E and Atlas Copco machines and blasting are the responsibility of Minera Yanacocha. The ore is transported 2.5km or more to the leach pads using wheeled loaders and 85t-capacity trucks, and is heaped by stackers. The steady-state mining rate is 544,000td.
Since the ore is porous, run-of-mine ore can be heap-leached without crushing and the solution treated by the Merrill Crowe process. The EPCM project manager for the start-up facility was Minproc International. Cyanide solutions are rendered harmless by the Inco process. Subsequent pit development required three more leach pads and two more process plants, while working La Quinua necessitated adding a 120,000td crushing and agglomeration facility in 2001.

quotThe Pierina deposit is located in the Calipuy belt of Miocene volcanic rocks near Huaraz in Central Peru. Most of the mineralized zone is stratiform and hosted by a gently dipping unit of felsic ash flow tuffs, but some ore occurs within and on the borders of breccia dikes that are associated with a felsic prophyry intrusion underlying the south side of the deposit.
