3D models for hydrothermal copper ore bodies at Sin Quyen deposit North Vietnam A case report for ore reserves and prediction of hidden mineral resource potential The 3D models combined with ore parameters and chemical analysis can evaluate ore reserves of different elements with low cost and less time consuming Table 1 Resource of some
The USGS also defines the term reserves base not to be confused with resource base to refer to economic marginally economic and some sub economic demonstrated resources USGS 2012a although the last time it reported reserves base data for copper was in 2009 with an estimate of 1000 Mt Cu USGS 2012b It is important to note that
Estimated worldwide reserves stand at around 870 million tonnes almost a quarter of which are located in Chile Largest copper producing countries in the world by 2020 mining production 1 Chile million tonnes Chile is the clear leader among the world s largest copper producing countries with million tonnes of the metal mined
Copper has for many years played an important role in Zambia s economy and the performance of the economy has followed the fortunes of copper mining closely This report investigates the role copper mining could play in achieving the government s objectives of increasing economic growth and jobs in the future
Ordinary kriging OK has been used widely for ore reserve estimation because of its superior characteristics in relation to other methods One of these characteristics is related to the quantification of uncertainty by the kriging variance However the kriging variance does not recognize local data variability which is an important issue in the process of ore reserve
These are copper ore bodies formed from hydrothermal fluids from magma chambers that lie deep below the deposit Sediment hosted deposits These deposits are formed when copper bearing fluids mix with permeable sedimentary and volcanic rocks Copper is primarily sourced from porphyry deposits which are concentrated in the Americas Therefore
Escondida located in the Atacama Desert in Northern Chile and owned by BHP is the world s largest copper mine based on its total copper reserves its production capacity as well as its actual

As of 31 December 2023 the Group copper ore reserves are 311 million tonnes at % copper containing million tonnes of copper as shown in summary Table 7 and in detail in Tables 10 and 11 Compared to 2022 copper ore reserves the ore reserves have increased by 632% underpinned by the Tujuh Bukit Copper Project Operations Table 14
The USGS also defines the term reserves base not to be confused with resource base to refer to economic marginally economic and some sub economic demonstrated resources USGS 2012a although the last time it reported reserves base data for copper was in 2009 with an estimate of 1000 Mt Cu USGS 2012b It is important to note that
The open pit mine was estimated to contain of fine copper 2 567Mt of ore reserve grading % copper at the beginning of 2013 The porphyry copper deposit was discovered in 1952 and has been operational since 1998 It is the first mine to be developed entirely by the state owned Codelco and produced 427 791t of copper and molybdenum
In the long term primary and secondary supply of refined copper satisfies demand Numerous models exist to explain and predict demand and secondary supply; however the projection of primary supply relies mostly on detailed knowledge of potential mining projects and on existing ore reserves and resources Much discussion has occurred historically
11 Canadian Copper Mining Facts #1 Canadian copper mines produced 475 898 tonnes in 2020 NRC #2 Canada s copper exports were valued at $ billion in 2020 NRC other copper mining projects in Canada began developing Qubec in the Precambrian Shield Eventually large copper reserves in the Cordillera of Western Canada were
working in the Chinese mining industry and institutions The 2012 JORC Code was first translated for the Joint Ore Reserves Committee and its parent bodies the Minerals Council of Australia The Australasian Institute of Mining and Metallurgy and the
An overview of copper and cobalt production from ore reserves and of global demand and supply risks for these metals is presented The potential benefits of reprocessing copper slag waste using
BHP is advancing its copper production ambitions in South Australia with the recent announcement by the South Australian Government marking a crucial step The State Government revealed
Copper reserves are expected to increase by million tons by 2025 million tons by 2030 and million tons by 2035 Furthermore two new copper resource camps will be established and nine large scale copper resource camps will be consolidated by then
Since 2000 with national investment in fundamental and public geological work great progress has been made in the discovery of domestic copper and the identified reserve of resources has steadily increased Zhang 2008 Zhang 2010 The 2015 China s Land and Resources Bulletin released by the Ministry of Land and Resources shows that in 2015 the
The JORC Code is produced by the Australasian Joint Ore Reserves Committee the JORC Committee The JORC Committee was established in 1971 and is sponsored by the Australian mining industry and its professional organisations
3 Despite increased demand for copper produced from ore in recent years increases in reserves have grown and there is more identified copper available to the world than at any other time in history In the period 2000 2022 396 million tonnes of copper have been mined In that same period however reserves have grown by
Ore Reserves at other mines and deposits Australia s Identified Mineral Resources covers 36 mineral commodities of which 31 have estimated Ore Reserves and 27 were actually in production in 2022 Table 2 For some commodities antimony magnesite and bauxite all of the Ore Reserves are associated with operating mines Figure 1
Copper mining in Australia Australia has a relative abundance of copper home to around 13% of the world s supply with only Chile boasting greater reserves However production has remained at the low end with GlobalData finding the country was the eighth largest producer last year
