Cariboo Copper Corp. 25 % Indirect
Taseko Mines Ltd. 75 % Indirect
On March 31, 2010, we established an unincorporated joint venture (“JV”) between Gibraltar Mines Ltd., and Cariboo Copper Corp. (“Cariboo”) over the Gibraltar copper and molybdenum mine (the “Gibraltar Mine” or “Gibraltar”), whereby Cariboo acquired a 25% interest in the Gibraltar Mine and we retained a 75% interest with Gibraltar Mines Ltd. operating the mine for the two JV participants. Cariboo is a Japanese consortium jointly owned by Sojitz Corporation (50%), Dowa Metals & Mining Co., Ltd. (25%) and Furukawa Co., Ltd. (25%).

Deposit Type

  • Porphyry


Summary:

The Gibraltar mine is a large calcalkaline copper-molybdenum porphyry deposit located about 10 km north of McLeese Lake, British Columbia, and hosted by tonalite of the Late Triassic Granite Mountain batholith.

The Gibraltar Mine is a bulk tonnage, low-grade copper-molybdenum deposit concentrated along hydrothermally altered shear zones within the Granite Mountain Batholith along the west slope of Granite Mountain. It is one of the lowest grade base metal deposits ever mined in British Columbia. It is also the first in the province to have the majority of its initial production from supergene ore.

Copper-molybdenum mineralized rocks at Gibraltar have been mined from four open pits, the Gibraltar East (093B 012), Gibraltar West (093B 007), Granite Lake (093B 013) and Pollyanna (093B 006) (Figure 4). The ore bodies mined form part of a semi-continuous, anastomosing mineralized shear zone up to 100 metres or more in thickness, that parallels the strike of the regional foliation. The shear zone and associated mineralization are affected by broad open folding and display a geometry similar to that described previously for the regional foliation. Sulphide mineralization develops within or marginal to the more schistose zones, and fades out into the more massive, less foliated quartz diorite, with mineralization confined largely to the foliation surfaces and narrow mineralized veinlets (Simpson, 1970). The best mineralization is found towards the center of the mineralized belt of schistose rocks. The main ore minerals are chalcopyrite, chalcocite (supergene) and molybdenite. Pyrite is common in both ore and peripheral alteration zones and also forms an extensive halo with a few percent pyrite that envelopes the mineralized shear.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Gibraltar deposits have been developed using open pit mining methods since the commencement of mining on site in 1971.

Current and future mining operations will be carried out utilizing conventional open pit mining equipment. The waste and ore are mined utilizing five electric blast hole drills, five electric rope shovels, one large front end loader and 26 haul trucks. The main mining fleet is supported by a fleet of ancillary equipment including track and rubber tired dozers, motor graders as well as sand and water trucks. The reserve mine plan does not require the purchase of any additional mine production equipment.

Summary:

The processing facilities at Gibraltar mine consist of two separate bulk sulphide concentrators, a dedicated molybdenum flotation plant, and a series of leach piles which feed a solvent extraction and electrowinning (SX/EW) facility.

Sulphide ore is processed at a design rate of 85,000 t/day through two bulk concentrators to produce a concentrate which contains both copper and molybdenum values. The bulk concentrate from both facilities is combined and processed through a single molybdenum flotation plant. The molybdenum concentrate from this plant is dewatered and bagged, and subsequently shipped to market. The tailings from this plant are the site’s final copper concentrate. This copper concentrate is dewatered and shipped in bulk to market.

Oxide ore from the mine is delivered to oxide leach dumps and heap pads. The Solvent Extraction and Electrowinning (SX/EW) plant is designed to extract copper from the pregnant leach solutions (PLS) collected from the site ........
