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 strata-bound copper deposits.
Oct 31, 2019· Overall, the three holes are designed to test different geophysical attributes related to an iron oxide copper gold breccia pipe target that is within, but locally cross-cuts the Ranoke magnetic ...
95 ZAMBIA: EXPLORATION POTENTIAL FOR IRON OXIDE COPPER–GOLD DEPOSITS AND A RE-EVALUATION OF THE COPPERBELT Craig R. Williams, Bruce W. Nisbet, Barry van der Stelt and Michael N. Richards
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.
Sep 17, 2003· Abstract. Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings.
According to ISO Technical Specification 80004, a nanoparticle is defined as a nano-object 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 size-related properties significantly different from those of either fine particles or bulk ...
This under-explored polymetallic gold district also exhibits similarities to the Idaho Cobalt Belt with Iron-Oxide-Copper-Gold ("IOCG")-like mineralization. The historic Scadding Mine, located within the SPJ Project, produced 144,000 tons of ore at a grade of 7.43 g/t gold (OFR 5771).
The discovery of iron oxide copper-gold (IOCG) mineralization at Prominent Hill in the Mount Woods inlier (South Australia) by Minotaur Resources Ltd. in November 2001 was based on an empirical ...
Iron-oxide-copper-gold deposits rank alongside porphyries as some of the world's largest deposits and most consistent in grade. However, the adage "once you've seen a few porphyries, you ...
Iron oxide copper-gold 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 ...
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 0.2% and 5% copper, with gold contents .
Sep 17, 2019· VR Confirms IP Anomaly at its Ranoke Copper-gold Property in Ontario, and Prospecting Discovers Iron Oxide Breccia in the Area
PDF | Iron oxide–copper–gold (IOCG) at Thanewasna, Maharashtra, India is a new genetic type of ore deposit, being reported from the western margin of Bastar craton, based on integrated field ...
to distinguish this group from sedimentary iron deposits, magmatic iron–titanium oxide deposits, and other iron oxide-bearing hydrothermal deposits, such as many members of the porphyry copper clan (Chapter 13.14). In particular, this usage does not restrict IOCG to those deposits containing economic concentrations of copper and(or) gold (cf ...
Jul 17, 2018· Abstract. Trace element compositions of magnetite and hematite from 16 well-studied iron oxide–copper–gold (IOCG) and iron oxide apatite (IOA) deposits, combined with partial least squares-discriminant analysis (PLS-DA), 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 ...
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 (IOCG) deposits defi ne a group of diverse, epigenetic Cu-Au deposits to which several economically important deposits belong. Their typical characteristics are: (1) Fe-Cu-Au-Co-U-REE-Ba-F element association, (2) high Fe-S ratio manifested by magnetite- and/or hematite-rich host
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.
The region has been recently identified as a promising Iron-Oxide-Copper-Gold district by the Geological Survey of Canada and we believe there is potential to define an IOCG deposit at Scadding. ...
Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings. The youngest and, therefore, most readily
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 Oxide-Copper-Gold (IOCG) deposits, has caused great interest in formation processes and characteristic guidelines that are useful for their ...

Halifax-based Zonte Metals (TSX-V: ZON) announced today it has signed an option agreement to acquire of the Cross Hills iron oxide copper-gold project, on the island portion of Newfoundland ...
Each metallogenic epoch introduced its own deposit type(s), of which porphyry copper (and related skarn), followed by sediment-hosted stratiform copper and then iron oxide copper-gold (IOCG), are globally preeminent. Nonetheless, genesis of the copper provinces remains somewhat enigmatic and a topic of ongoing debate.
