An evaluation of geochemical sampling in the search for concealed ‘porphyry’ copper-molybdenum deposits on (). Biogeochemical prospecting for molybdenum in west-central British Columbia. (Chahfiruzeh porphyry) intruded into older basaltic and andesitic lava flows and pyroclastic rocks. Alteration assemblages and alteration zoning, typical of porphyry copper deposits, are well developed. Mineralization occurs in quartz-sulfide stockworks and as sulfide disseminations in the porphyritic intrusion and the immediate wall rocks.
SUMMARY The Anyox copper mining camp played a key role in the early development of northwestern British Columbia. It was discovered in and through persistence and belief in the project (a common theme in modern exploration), it was explored and brought into production in by Granby Consolidated Mining, Smelting and Power Co., Ltd.

The Mesozoic-Cenozoic history of the Canadian Cordillera in British Columbia was composed of five major stages: preaccretion island arc development in the Early Jurassic, micro-plate vs. continent collision in the Middle Jurassic, uplift and extension in the Late Jurassic to Early Cretaceous, renewed collisional tectonics in the Middle Cretaceous, and extension and strike-slip faulting in the Cited by: Peak values in soils over the target exceed 1, ppm copper.

Porphyry copper and molybdenum deposits West-Central British Columbia. Victoria, B.C., Canada: Ministry of Energy, Mines and Petroleum Resources, [i.e. ] (OCoLC) Porphyry copper and molybdenum deposits in west-central British Columbia are associated with plutons of Late Cretaceous and Tertiary age which intrude Mesozoic volcanic and sedimentary rocks of the Intermontane Tectonic Belt.
The porphyry deposits are contained in an area bounded on the west by granitic rocks of the Coast Plutonic Complex, and on the east and southeast by a belt containing Cited by: 5.

Gold grades are less than ppm in the porphyry copper-molybdenum. Berg copper-molybdenum deposit is in mountainous terrain of the Tahtsa Range in west-central British Columbia. It is a type example of Lowell and Guilbert's () model of porphyry copper deposits.
The deposit is in thermally metamorphosed and hydrothermally altered Middle Jurassic volcanic rocks and Tertiary quartz diorite adjacent to a weakly mineralized Eocene stock. The stock is about.
Overview. The Ootsa Lake Property is a located in west-central British Columbia, Canada and hosts two Porphyry Copper deposits (Seel and Ox deposits) and high grade gold-silver veins (Damascas and Captain Veins).
The property % owned by Gold Reach Resources who is a subsidary of Ootsa Lake Resources Inc., however the Seel Deposit Claims has a Net Smelter Royalty (NSR) of.
Porphyry deposits are the world's most important source of Cu and Mo, and are major sources of Au, Ag, and Sn; significant byproduct metals include Re, W, In, Pt, Pd, and Se. Optimum conditions for development of giant porphyry copper deposits Porphyry Copper Deposit Model porphyry copper deposits generally form in the upper crust (less than 5–km depth) in tectonically active convergent margins and commonly in areas that are elevated and(or) subject to high uplift rates.

Apatite is a common resistate mineral occurring in a range of host rocks and ore-related hydrothermal alteration assemblages. Apatite in several porphyry copper deposits in British Columbia has a unique set of physical and compositional characteristics that can be used to evaluate the chemical conditions of magmas that formed the causative intrusions or associated hydrothermal by: Canadian Cataloguing in Publication Data Panteleyev, Andrejs, Berg porphyry copper-molybdenum deposit.

Batu Hijau contains million tonnes (Mt) of ore at an average grade of percent copper ( Mt Cu) and g/t gold ( tonnes Au), at a cutoff grade of percent Cu (Clode et al., ).
The. The name porphyry comes from the Latin for its colour purple and has associations with royal or imperial qualities dating back to the Romans. In Canada, British Columbia enjoys the lion’s share of this rock, which contains the largest resources of copper, significant molybdenum and 50% of. Models for such dispersion (e.g., Bright, ; Thomas and Galey, ) have been based largely on detailed studies of "Climax-type" porphyry molybdenum deposits (White et al., ) and exploration for quartz-monzonite type porphyry molybdenum deposits has at times suffered because of the paucity of avail- able geochemical data on their Cited by: 6.
Porphyry Cu-Mo deposits, in particular Highland Valley Copper, account for a large proportion of B.C. molybdenum production, resources, and reserves as a by-product of copper production.

The Berg deposit in west-central British Columbia, Canada, is related to a middle Eocene (49± Ma) stock which intrudes middle Jurassic Hazelton Group volcanics, some 14 km to the east of the Coast Plutonic Complex.
Regionally however, numerous stocks ranging in age from lower Jurassic to upper Eocene are found to the east of the Coast Plutonic.
