Due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. The known world class Cu-Mo deposit, Sarcheshmeh Porphyry deposit (central Iran) selected as the study area. The Hypogene zone of the deposit was chosen as the space in which estim...

Jiama is a super-large porphyry copper–polymetallic deposit located in the Gangdese metallogenic belt of southern Tibet. The consists combination polymetallic skarn, Cu–Mo mineralization at contact between Porphyry and hornfels, distal Au fault. current metal reserves are 7.4 Mt Cu, 0.6 Mo, 1.8 Pb–Zn, 6.65 Moz Au, 360.32 Ag, with skarn to porphyry–hornfels host-rock ratio ~3:1. Based on detaile...

The Qulong porphyry copper and molybdenum deposit is located at the southwest margin of the Lhasa Terrane and in the eastern region of the Gangdese magmatic belt. It represents China’s largest porphyry copper system, with ∼2200 million tonnes of ore comprising 0.5 % Cu and 0.03 % Mo. The mineralization is associated with Miocene granodiorite, monzogranite and quartz-diorite units, which intrude...

This paper documents the exploration significance of Ag/Au, Au/Cu, Cu/Mo and (Ag×Au)/Cu×Mo) ratios of the supra-ore and sub-ore halos versus fluid inclusion evolution for 24 Cu, 6 Cu- Mo and 10 Cu-Au porphyry deposits worldwide. The ratios are based only on the economic and mineralized hypogene alteration zones. The results indicate that (Ag×Au)/(Cu×Mo), Au/Cu and Cu/Mo ratios increase with dec...

This paper describes the application of a new multi-criteria decision making (MCDM) technique called fuzzy outranking to map prospectivity for porphyry Cu Mo deposits. Various raster-based evidential layers involving geological, geophysical, and geochemical geo-data sets are integrated for mineral prospectivity mapping (MPM). In a case study, 13 layers of the Now Chun deposit located in the Ker...

Remote sensing plays an important role in mineral exploration. One of its proven applications is extracting host-rock lithology and alteration zones that are related to porphyry copper deposits. An Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used to map the Baogutu porphyry deposit alteration area. A circular alteration mineral zoning pattern was clearly observed ...

The Yuleken porphyry Cu-Mo deposit located in the Chinese Altay-East Junggar, a section of Central Asian Orogenic Belt, world's largest Phanerozoic subduction-accretionary orogen, witnessed multistage tectonic-magmatic evolution and mineralization from arc to syn- post-collision environment over time span about 52 Ma. Four types molybdenite have been distinguished: (1) primary magmatic-hydrothe...

supergene oxidation-leaching and secondary sulfide enrichment in the sarcheshmeh porphyry cu-mo deposit generated a supergene profile to depths of 20 to 80 meters with oxide ore reserve about 22 mt. @1.08% cu and sulfides ore [email protected]% cu. geochemical distribution and behavior of trace metals associated with cu namely mo, au, and ag in the supergene profile of the sarcheshmeh were po...
