“…The USGS Three-part Undiscovered Mineral Resource Assessment provides an estimate of the number and quality of undiscovered deposits within a given region. The basic concepts of the Assessment were initially developed at the USGS (Singer 1975) and have since been applied at several scales, from global (Drew and Menzie 1993) to province (Lisitsin et al 2014), and for several commodities including nickel (Rasilainen et al 2016), copper (Hammarstrom et al 2005) and gold (Lisitsin et al 2014).…”

The United States Geological Survey (USGS) Three-part Undiscovered Mineral Resource Assessment provides a framework for estimating undiscovered mineral endowment. Previous studies that applied the Three-part Assessment to estimate the undiscovered orogenic gold endowment of the Sandstone Greenstone Belt, Western Australia, have relied upon dated or expert-derived grade-tonnage models. Here, several assessments are conducted using local grade-tonnage models, comprising known orogenic gold deposits within the entire Yilgarn Block and several individual terranes with contrasting lithosphere-to terrane-scale characteristics. These models are generated through comprehensive review of historical exploration, resource and production data. Based on these models, the Sandstone Greenstone Belt is estimated to contain significant undiscovered gold mineralisation, with a median total endowment of between 166 and 298 t gold, and mean of 167-319 t gold. Although these updated grade-tonnage models provide an approximately 80 per cent variation in predicted gold endowment, it is still evident that the belt remains an underexplored region within the Yilgarn Block, Western Australia.

“…The global mineral resources assessment will provide a consistent, comprehensive level of information and analysis of undiscovered global nonfuel mineral resources. The assessment results will provide all nations with a regional and global context for planning sustainable development, evaluating their known and undiscovered nonfuel mineral resources, designing new mineral exploration, anticipating and preventing environmental problems, and making land -use decisions (Hammarstrom et al, 2006).…”

Sustainable development involves meeting the needs of human societies while maintaining viable biological and physical Earth systems. To attract responsible exploration and mining, governments of mining nations will need to provide: regional-scale geo-scientific datasets as required to attract and guide future generations of exploration; resource access through multiple and sequential land use regimes, and frameworks for dealing with indigenous peoples' issues; and arrangements for consideration of mining proposals and regulation of mines that ensure responsible management of environmental and social issues. The minerals industry will need to continue to pursue advances in technologies for exploration, mining, processing, waste management and rehabilitation, and in public reporting of environmental and social performance (Lambert, 2001).

“…The global demand for mineral and petroleum resources is increasing (Hammarstrom, Briskey, Schulz, Peters, & Bawiec, 2006), attracting the major mining players to SSA where they invest heavily and develop infrastructure (Edwards et al, 2014;Janneh & Ping, 2011). This investment has led to an unprecedented upsurge in mining activities in SSA.…”

Where are mines located insub SaharanAfrica and how have they expanded overtime?

Mining is a multi-billion-dollar industry spanning major to artisanal and small-scale mines, with diverse local to regional socio-economic and environmental impacts. Sub Saharan Africa (SSA) has large deposits of minerals, which has made it a global epicenter for investors in the extractive industries. Here, we identified and mapped 469 company-owned and community-managed mines across SSA, most of which are formal, to explore their distribution and areal extents and understand the potential threats they pose to conservation. The dominant eight commodities in SSA are gold, copper, iron, limestone, uranium, diamond, bauxite and petroleum, making up 405 mines and occupying 85% of the 3,055 km 2 total areal extent. Mining significantly expanded between 2000 and 2018, with 260 (58%) new mines created and major expansion of many older mines. Hotspots of mining activity are apparent in the copper-belt of the Democratic Republic of Congo and Zambia, Ghana and the Niger-Delta region of Nigeria. These mining 'hotspots' are distributed in close proximity to regions of high carbon stocks and value to biodiversity conservation, with the areal extent of mines more than doubling between 2000 and 2018 to 1,192 km 2 within 10 km of a protected area, suggesting susceptibility to deforestation and other environmental consequences. The identification of mines and their changing spatial extent is imperative for monitoring future encroachments in SSA and to conservation and habitat recovery. Furthermore, Africa needs to introduce sustainable mineral development policies to safeguard and protect its forests, especially reducing the frequency of protected area downgrading, downsizing and degazettement events.
