Mineral Resource Classification
There are several classification systems for the economic evaluation of mineral deposits worldwide. The most commonly used schemes base on the International Reporting Template, developed by the CRIRSCO – Committee for Mineral Reserves International Reporting Standards, like the Australian Joint Ore Reserves Committee – JORC Code 2012, the Pan-European Reserves & Resources Reporting Committee' – PERC Reporting Standard from 2021, the Canadian Institute of Mining, Metallurgy and Petroleum – CIM classification and the South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC). A more detailed description of the historical development concerning reporting about mineral deposits can be found on the PERC web site. In 1997, the United Nations Framework Classification for Resources (UNFC) was development by the United Nations Economic Commission for Europe (UNECE). The Pan African Resource Reporting Code (PARC) is based on UNFC. Mineral resources ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PERC Reporting Standard
ThPERC Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (the ‘PERC Reporting Standard’ sets out the minimum standards, as well as additional guidelines and recommendations for the Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves within Europe. It applies to all solid mineral raw materials for which Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves is required by any relevant regulatory authority. The PERC Reporting Standard is fully aligned with the 'CRIRSCO International Reporting Template''.

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Instrument 43-101
National Instrument 43-101 ''Standards of Disclosure for Mineral Projects'' ("NI 43-101") is a securities regulatory instrument that governs how companies can disclose mining-related information in Canada. Its rules aim to prevent companies from sharing inaccurate or misleading information about their mineral assets with prospective investors and the public. It is overseen and enforced by the Canadian Securities Administrators. NI 43-101 applies broadly to companies both public and private, and to a variety of disclosures types including mineral exploration reports, reporting of resources and reserves, presentations, oral comments, and websites. NI 43-101 covers mineral products such, precious metals and solid energy commodities as well as bulk minerals, dimension stone, precious stones and mineral sands commodities.

Ore Genesis
Various theories of ore genesis explain how the various types of mineral deposits form within Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined. Ore-genesis theories generally involve three components: source, transport or conduit, and trap. (This also applies to the petroleum industry: petroleum geologists originated this analysis.) *''Source'' is required because metal must come from somewhere, and be liberated by some process. *''Transport'' is required first to move the metal-bearing fluids or solid minerals into their current position, and refers to the act of physically moving the metal, as well as to chemical or physical phenomena which encourage movement. *''Trapping'' is required to concentrate the metal via some physical, chemical, or geological mechanism into a concentration which forms mineable ore. The biggest deposits form when the source is large, the transport mechanism is efficient, and the trap is active and ready at the r ...

Mineral Exploration
Mining engineering is the extraction of minerals from the ground. It is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. History of mining engineering From prehistoric times to the present, mining has played a significant role in the existence of the human race. Since the beginning of civilization, people have used stone and ceramics and, later, metals found on or close to the Earth's surface. These were used to manufacture early tools and weapons. For example, high-quality flint found in northern France and southern England were used to set fire and break rock. Flint mines have been found in chalk areas where seams of the stone were followed underground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mineral Economics
Mineral economics is the academic discipline that investigates and promotes understanding of economic and policy issues associated with the production and use of mineral commodities. Mineral economics ��min·rəl ‚ek·ə′näm·iksis specially concerned with the analysis and understanding of mineral distribution as well as the ‘discovery, exploitation, and marketing of minerals’. Mineral economics is an academic discipline which constructs policies regarding mineral commodities and their global distribution. The discipline of mineral economics examines the success and the implications associated with the mining industry and the impact the industry has on the economy socially and regarding the climate. Mineral economics is a continuing, evolving field which originally started after the Second World War and has continued to expand in today's modern climate. The identification of mineral sectors and their associated total revenue from specific commodities and how this varies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Geology
Economic geology is concerned with earth materials that can be used for economic and industrial purposes. These materials include precious and base metals, nonmetallic minerals and dimension stone, construction-grade stone. Economic geology is a subdiscipline of the geosciences; according to Lindgren (1933) it is “the application of geology”. It may be called the scientific study of the Earth's sources of mineral raw materials and the practical application of the acquired knowledge. The study is primarily focused on metallic mineral deposits and mineral resources. The techniques employed by other Earth science disciplines (such as geochemistry, mineralogy, geophysics, petrology, paleontology and structural geology) might all be used to understand, describe and exploit an ore deposit. Economic geology is studied and practiced by geologists. Economic geology may be of interest to other professions such as engineers, environmental scientists and conservationists because of the ...

Governance
Governance is the overall complex system or framework of Process, processes, functions, structures, Social norm, rules, Law, laws and Norms (sociology), norms born out of the Interpersonal relationship, relationships, Social interaction, interactions, Power (social and political) , power dynamics and communication within an organized group of individuals. It sets the boundaries of acceptable conduct and practices of different actors of the group and controls their decision-making processes through the creation and enforcement of rules and guidelines. Furthermore, it also manages, allocates and mobilizes relevant resources and capacities of different members and sets the overall direction of the group in order to effectively address its specific collective needs, problems and challenges. The concept of governance can be applied to social, political or economic entities (groups of individuals engaged in some purposeful activity) such as a Country, state and its government (pub ...

Mineral Processing
Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling. Beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings). There are many different types of beneficiation, with each step furthering the concentration of the original ore. Key is the concept of recovery (mineral processing), recovery, the mass (or equivalently molar) fraction of the valuable mineral (or metal) extracted from the ore and carried across to the concentrate. History Before the advent of heavy machinery, raw ore was broken up using hammers wielded by hand, a process called "''spalling''". Eventually, mechanical means were found to achieve this. For instance, stamp mills were being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Mineral Reporting Codes
The South African Mineral Reporting Codes (SAMCODES) are codified sets of standards and guidelines applicable to the South African Minerals and Petroleum Industries, drafted and overseen by the SAMCODES Standards Committee (SSC), a professional and non-governmental body. Specifically, the standards and guidelines are applicable to public reports compiled on behalf of South African Minerals and Petroleum companies for the benefit of investors. The Codes are incorporated into Section 12 of the Johannesburg Stock Exchange (JSE) Listings Rules, which detail "the criteria for the listing of, and the additional disclosure requirements for Mineral Companies and, in certain circumstances, substantial mineral assets of non-Mineral Companies" in South Africa. As such, the SSC acts in an advisory capacity to the JSE, ensuring that reports submitted for listings consideration are compliant with the SAMCODES. The Codes set out minimum standards for Public Reporting of Exploration Results, Mine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geologist
A geologist is a scientist who studies the structure, composition, and History of Earth, history of Earth. Geologists incorporate techniques from physics, chemistry, biology, mathematics, and geography to perform research in the Field research, field and the laboratory. Geologists work in the Energy industry, energy and mining sectors to exploit Natural resource, natural resources. They monitor environmental hazards such as earthquakes, volcanoes, tsunamis and landslides. Geologists are also important contributors to climate change discussions. History James Hutton is often viewed as the first modern geologist. In 1785 he presented a paper entitled ''Theory of the Earth'' to the Royal Society of Edinburgh. In his paper, he explained his theory that the Earth must be much older than had previously been supposed to allow enough time for mountains to be eroded and for sediments to form new rocks at the bottom of the sea, which in turn were raised up to become dry land.
