The Iron Mask batholith is lo cated 10 km south west of Kamloops (Fig. 1). It is the source of Cu-Au-Ag pro duced from por phyry de pos its such as Afton, Cres cent, Pothook, Ajax West and Ajax East, as well as struc tur ally con trolled Cu-mag ne tite veins (Iron Mask, Makaoo, Grey Mask). Cur rently, it is the tar get of ex plo ra tion for Cu-Au-Ag-Pd min er al iza tion by DRC Re sources at th...

The magmatic-hydrothermal evolution of porphyry-style mineralization in the shallow crust that is linked to magmatic processes at depth has been extensively studied using bulksample isotopic analysis combined with relative timing constraints. However, a lack of evaluation of the fluid evolution process against an absolute time frame limits further understanding of the ore-forming process. Here,...

The Kuh Zar Au-Cu deposit is located about 100 km southeast of Damaghan city. Structurally, this area is part of the Alborz Magmatic Assemblage (AMA). The oldest rock units in the Firuzeh-Gheychi area consists of syenogranite and tourmaline biotite granodiorite units. These units were intruded by quartz monzonite porphyry stocks. Pyroxene diorite porphyry and hornblende diorite porphyry are you...

the darreh-zar porphyry copper deposit, located in the urumieh – dokhtar magmatic belt, lies about 10 km southeast of sar-cheshmeh porphyry copper deposit. the ore body with hydrothermally altered zones including potassic, chlorite-sericite, sericite, argillic and propylitic all related to the darreh-zar porphyry stock intruded the eocene volcanic rocks. pyrite, chalcopyrite, molybdenite, with ...

The Khezr-Abad area is located in southwest of Yazd in central Iran at the intersection with the Central Iranian Volcano-Plutonic Belt (Urumieh-Dokhtar Belt). The Darreh-Zerreshk and Ali-Abad porphyry copper deposits are the most important deposits in this district. These deposits are associated with Oligocene-Miocene (18-28 Ma) granitoid intrusions which consisted mainly of quartzmonzonite, qu...

The study area is located in Jabal-Barez Ranges, southeastern part of Kerman Copper Belt (KCB), where the porphyry copper mineralization such as Kerver occurs. This article deals with the enhancement of hydrothermal alteration minerals for exploration of porphyry Cu mineralization, and differentiates intense hydrothermal alteration zones from those with low intensity. Shortwave Infrared (SWIR) ...

The Casino Cu–Au–Mo deposit is one of the largest and highest-grade porphyries its kind in Canada, residing an unglaciated region west-central Yukon. A batch 22 stream water samples eight groundwater were collected proximal to for purpose identifying most diagnostic trace element isotopic pathfinders associated with hydrothermal mineralization, as well establishing natural hydrogeochemical base...

This paper presents a quantitative modeling for delineating alteration zones in the hypogene zone of the Miduk porphyry copper deposit (SE Iran) based on the core drilling data. The main goal of this work was to apply the Ordinary Kriging (OK), Artificial Neural Networks (ANNs), and Concentration-Volume (C-V) fractal modelings on Cu grades to separate different alteration zones. Anisotropy was ...
