Global greenhouse gas (GHG) emissions from gold mining exceed 100 Mt CO2-e annually, with country intensity 129 to 2754 kg CO2-e/oz, yet clear knowledge gaps remain regarding contributions, reduction potential, and impact of carbon pricing. The cost impacts upon global miners the introduction a hypothetical US$50/t US$100/t price are quantified affordable. Carbon vary markedly between countries, increasing production costs on average by US$13 per ounce in Finland up US$275/oz South Africa....
The banded iron formation (BIF)-hosted ore deposits in the lower greenstone succession of Koolyanobbing belt, 50 km north Southern Cross Western Australia, are a ∼200 Mt high-grade Fe (>58%) pre-mining resource and represents one most important districts Yilgarn craton. Four hypogene alteration (ore-forming) stages supergene upgrading event took place: (1) During stage 1, LREE-depleted, transition metal-enriched, Mg-Fe (±Ca) carbonates replaced quartz BIFs. deposit-scale was likely induced...
The Archean Yilgarn Craton in Western Australia represents one of the key areas for investigating mechanisms crustal growth during Earth's infancy. far-eastern margin has, however, received limited scientific scrutiny. In this study, in-situ zircon petrochronology (U-Pb, O, and Lu-Hf isotopes) is used to constrain formation evolution easternmost Yamarna Burtville regions as well encompassing Eastern Goldfields (Super)Terrane (EGT) Craton. new data highlight unequivocal existence relatively...
Abstract Although the lode-gold deposits of Yilgarn block are hosted by a variety rocks, and their structural style, associated alteration ore mineralogy also variable, common parameters suggest that they represent coherent group epigenetic deposits, most which formed during widespread (500 000 km 2 ) broadly synchronous (2635 ± 10 Ma) hydrothermal event in closing stages Late Archaean tectonothermal evolution host granitoid-greenstone terrains. Progressive variations deposit can be...
