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...
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...

The surface geochemistry techniques widely employed during the 1960’s to 1980’s are effective at discovering near-surface deposits, but are largely ineffective for exploring under deep cover or for deep extensions of known mineralisation in a near-mine environment. Instead, mineral explorers must focus their attention on rapidly aggregating and synthesising disparate data to build into holistic...
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.
Porphyry Cu–Au deposits are the major global source of copper, an essential metal for green transition, and a significant gold. They occur both in thick continental thin oceanic arcs at depths between ∼1 ∼6 km above parental magma chambers situated ∼5–15 depth. Although it is believed that precipitation processes these same arcs, not clear why porphyry two environments display different Cu Au e...
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...
