Sari Gunay epithermal gold deposit was selected in order to assess the application of biogeochemical exploration for gold in northwestern Iran. In this study, four sites were sampled in a profile perpendicular to mineralized vein with a control site two km far-off mineralized : Behzad Mehrabi, Hassan Alimohamdai, Mahin Farhadian Babadi, Farrokh Ghahremani Nejad.

      Finlay Minerals Ltd. is pleased to announce the discovery of porphyry intrusive (granitic) related copper- molybdenum and volcanic hosted copper mineralization on its % owned Silver Hope project in central British Columbia. A program of approximately 2, metres of diamond core drilling has been completed in . 3. Biogeochemical Approach -Metabolism and Biogeochemical Cycles In this section, some research is introduced which takes a biogeochemical approach to river systems. "Biogeochemical processes in river systems" can be rephrased as “metabolism,” “biogeochemical cycle,” or “exchange process.” These processes are shown in Figure 1.

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.

The largest porphyry copper deposit of the Canadian Cordillera is approximately one billion tonnes with grades just under % copper; most are much smaller.

At the present time, approximately half the world’s copper reserves, 60% of Canadian copper resources, and 90% of British Columbia’s reserves are contained in porphyry deposits. The distribution of the nine metal elements in 20 desert plants was studied in order to detect the indicator value of these plants for mineral prospec Cited by:   Table of Attributes of Porphyry Copper Deposits and Prospects, British Columbia and Yukon Territory, Canada (given in several file formats) Appendix H GIS data zip.

The role of indicator plants in geobotanical methods of mineral exploration is reviewed. Some 85 species are discussed and a critical examination is made of their probable role in indicating the presence of aluminum boron, cobalt, copper, gold, iron, lead, manganese, nickel, selenium, silver, uranium and.

A paper published in Nature Communications reports that trees sip up gold deposits below, a find that could help prospectors pinpoint the location of buried reserves.

We investigated biogeochemical cycling of dissolved copper (dCu) along the Line P transect, spanning from the coastal waters of British Columbia, Canada, to the High Nutrient, Low Chlorophyll.Plant indicators, as used in Geobotanical prospecting, are plant species, or smaller intraspecific entities or taxa, or their natural assemblages (plant communities) which show a sufficiently constant association with substrates enriched in heavy metals, such that the occurrence of heavy metals can be deduced merely from the presence of those Cited by: 2.Abstract [1] An “anthrobiogeochemical” copper cycle, from Earth's core to the Moon, combining natural biogeochemical and human anthropogenic stocks and flows is derived for the mids.

Although some aspects of the quantification have moderate to high uncertainty, the anthropogenic mining, manufacturing, and use flows (on the order of 10 4 Gg Cu/yr) clearly dominate the cycle.
