Iron oxide copper gold ore deposits are important and highly valuable concentrations of copper, gold and uranium. With an tendancy for being tremendous in size, relatively simple metallurgy and ...
to distinguish this group from sedimentary iron deposits, magmatic iron–titanium oxide deposits, and other iron oxidebearing hydrothermal deposits, such as many members of the porphyry copper clan (Chapter ). In particular, this usage does not restrict IOCG to those deposits containing economic concentrations of copper and(or) gold (cf ...
Halifaxbased Zonte Metals (TSXV: ZON) announced today it has signed an option agreement to acquire of the Cross Hills iron oxide coppergold project, on the island portion of Newfoundland ...
Exploring Iron Oxide Copper Gold Deposits. November 2017 by Chris Ralph. The excitement over IOCG deposits began with the discovery of a monster deposit at Olympic Dam in Australia in 1976. The discovery was accidental as the operator was searching for stratabound copper deposits.
Jan 25, 2012· In the little handbook that accompanied my Garret Gold Trap Kit, it is mentioned that the odd nugget, in some areas, may not be golden, but rather black or dark gray on it''s surface, due to certain environmental conditions.
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between % and 5% copper, with gold contents .
The iron oxide coppergold (IOCG) group of deposits, initially defined following discovery of the giant Olympic Dam CuUAu deposit, has progressively become tooembracing when associated deposits and potential end members or analogs are included. The broader group includes several low Ti iron oxide

This underexplored polymetallic gold district also exhibits similarities to the Idaho Cobalt Belt with IronOxideCopperGold ("IOCG")like mineralization. The historic Scadding Mine, located within the SPJ Project, produced 144,000 tons of ore at a grade of g/t gold (OFR 5771).
Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold. • The gold is present as native gold, electrum, and gold–bismuth–antimony–tellurium alloy. • The gold distribution is controlled by gold contents in host rocks and the efficiency of precipitation mechanism.
The region has been recently identified as a promising IronOxideCopperGold district by the Geological Survey of Canada and we believe there is potential to define an IOCG deposit at Scadding. ...

Wild Acre Metals inked a drilling deal for its Chaparra iron oxide copper gold project in Peru, it will also aim several projects with deep reverse circulation drilling totaling about 1,200 meters, comprising, the northern boundary of the western anomaly, magnetic gravity highs in the western and south eastern part and the central low zone.
South Australia hosts some of the world''s most significant iron oxidecoppergold (IOCG) deposits. Since the discovery of Olympic Dam, IOCG deposits have been recognised elsewhere in the Gawler Craton and in a number of terranes worldwide.
Iron oxidecoppergold potential of the southern Arunta Region Iron oxidecoppergold (IOCG) deposits are a diverse family of mineral deposits unified by a number of common geological features, including the presence of abundant iron oxides, extensive hydrothermal alteration and strong structural controls (Williams et al., 2005). As well as copper
According to ISO Technical Specification 80004, a nanoparticle is defined as a nanoobject with all three external dimensions in the nanoscale, whose longest and shortest axes do not differ significantly, with a significant difference typically being a factor of at least 3. Nanoparticles can exhibit sizerelated properties significantly different from those of either fine particles or bulk ...

The discovery of the Olympic Dam, and its definition as a new type of copper deposit with important resources and other commodities (Fe, Au, U) and Iron OxideCopperGold (IOCG) deposits, has caused great interest in formation processes and characteristic guidelines that are useful for their ...
Iron oxide coppergold deposits (IOCG) comprise a type of mineralization formed in the geological time scale, from the Archean to Phanerozoic with most important occurrences in Australia and South America but also in Africa (Nisbet et al., 2000; Williams et al., 2005). Generally, these deposits contain massive and disseminated iron oxides ...
Oct 01, 2019· MacDonald''s reinterpretation of the geological model at the Scadding Deposit and larger SPJ property indicates that it could host a goldrich IronOxideCopperGold .
IOCG Iron Oxide Copper Gold Ore Deposits goes with porphyries as they are also loosely associated with a large felsic intrusions and form at moderate depths, unlike the dominantly tertiary porphyries IOCG''s tend to be much older and are generally protoizoic in age from to billion years ago.
Jul 17, 2018· Abstract. Trace element compositions of magnetite and hematite from 16 wellstudied iron oxide–copper–gold (IOCG) and iron oxide apatite (IOA) deposits, combined with partial least squaresdiscriminant analysis (PLSDA), were used to investigate the factors controlling the iron oxide chemistry and the links between the chemical composition of iron oxides and hydrothermal processes, as ...
