Grade-cost relationships within Australian underground gold mines – A 2014–2017 empirical study and potential value implications

Quantitative analysis of publicly reported quarterly cost data from 23 Australian underground gold mines in the period 2014–2017 identifies consistent, statistically significant, relationships between gold grade and costs at the individual mines. Higher gold grades are...

Comparing different real option valuation approaches as applied to a copper mine

One of the main challenges in valuing an option where the underlying is an infrequently traded ‘real’ asset, such as a mining project, is the complexity and potential bias inherent in determining the volatility of its operating cash flows. This, of course, is not th...

The spatial-temporal patterns of land cover changes due to mining activitiesin the Darling Range, Western Australia - A Visual Analytics Approach

The Darling Range in Western Australia is a major bauxite producing region. Clearing, excavation and rehabilitation activities related to bauxite mining have influenced land cover within this region since mining commenced in the 1960s. This paper presents a study that used mach...

Petrogenesis of the Paleoproterozoic (Orosirian) A-type granitesof Carajás Province, Amazon Craton, Brazil: Combined in situ Hf-O isotopes of zircon

We present new Lu\\Hf and Oxygen isotopic analyses and complementary whole-rock Nd isotopic data for three A-type Paleoproterozoic suites (1880Ma to 1857Ma; Serra dos Carajás, Velho Guilherme, and Jamon) and related granites of the Carajás Province, eastern Amazon...

A new 3.59 Ga magmatic suite and a chondritic source to the east Pilbara Craton

The Pilbara Craton, Western Australia hosts one of the best-preserved Paleoarchean granite-greenstone terrains on Earth, and is inferred to have developed on an older (> 3.8 Ga), possibly Hadean, continental substrate. Such ancient crust has, however, never been identified i...

Paleoproterozoic volcano-sedimentary series in the ca. 2.27–1.96 Ga Birimian Orogen of the southeastern West African Craton

The ca. 2270–1960 Ma accretionary-collisional Birimian Orogen in the southern West African Craton (sWAC) contain a number of volcano-sedimentary series, which were deposited in basins that developed during the regional Eburnean collisional orogeny (ca. 2160–1960 Ma)...
