Mineral Resource:

A mineral resource is a concentration or occurrence of solid material of economic interest in or on the Earth’s crust (Canadian Institute of Mining, Metallurgy and Petroleum [CIM]). It includes both discovered and undiscovered deposits and is estimated based on geological information. Mineral resources have reasonable prospects for eventual economic extraction. There are different types of mineral resources based on the level of geological knowledge and confidence, including inferred, indicated, and measured resources. These resources are typically identified through sampling and other data collected by geologists.

Key Facts

  • A mineral resource refers to a concentration or occurrence of solid material of economic interest in or on the Earth’s crust.
  • It includes both discovered and undiscovered deposits.
  • Mineral resources are estimated based on geological information and have reasonable prospects for eventual economic extraction.
  • There are different types of mineral resources based on the level of geological knowledge and confidence, such as inferred, indicated, and measured resources.
  • Mineral resources are typically identified through sampling and other data collected by geologists.

Mineral Reserve:

  • A mineral reserve is a subset of a mineral resource that has been demonstrated to be economically and legally extractable.
  • It represents the portion of a mineral resource that can be extracted at a profit.
  • Mineral reserves are usually based on detailed exploration, engineering, and economic feasibility studies.
  • They are subject to more stringent requirements and criteria than mineral resources.
  • Mineral reserves are used to determine the feasibility and profitability of a mining project[3].

Mineral Reserve

A mineral reserve is a subset of a mineral resource that has been demonstrated to be economically and legally extractable. It represents the portion of a mineral resource that can be extracted at a profit. Mineral reserves are usually based on detailed exploration, engineering, and economic feasibility studies and are subject to more stringent requirements and criteria than mineral resources. They are used to determine the feasibility and profitability of a mining project.

Key Differences

  • Definition: A mineral resource is a concentration of solid material of economic interest, while a mineral reserve is a subset of that resource that has been demonstrated to be economically and legally extractable.
  • Basis: Mineral resources are estimated based on geological information, while mineral reserves are based on detailed exploration, engineering, and economic feasibility studies.
  • Confidence: Mineral resources have varying levels of geological knowledge and confidence, while mineral reserves have a higher degree of geological confidence.
  • Economic Viability: Mineral resources have reasonable prospects for eventual economic extraction, while mineral reserves are economically and legally extractable.
  • Purpose: Mineral resources provide an indication of the potential for future development, while mineral reserves are used to determine the feasibility and profitability of a mining project.

Conclusion

Mineral resources and reserves are essential concepts in the mining industry. Mineral resources represent the potential for future development, while mineral reserves are the economically viable portion of those resources. Understanding the differences between these two terms is crucial for evaluating the potential of a mining project and making informed investment decisions.

  • Purpose: Mineral resources provide an indication of the potential for future development, while mineral reserves are used to determine the feasibility and profitability of a mining project.

How are mineral resources and reserves estimated?

Mineral resources are estimated based on geological information, including sampling, drilling, and geophysical surveys. Mineral reserves are estimated based on detailed exploration, engineering, and economic feasibility studies, which include resource estimation, mine design, and financial analysis.

What factors affect the economic viability of a mineral reserve?

The economic viability of a mineral reserve is affected by various factors, including the grade and quantity of the mineral deposit, mining and processing costs, transportation costs, market demand, and political and regulatory factors.

Why is it important to distinguish between mineral resources and mineral reserves?

Distinguishing between mineral resources and mineral reserves is important because it provides a clear understanding of the economic potential of a mining project. Mineral resources indicate the potential for future development, while mineral reserves represent the economically viable portion of those resources. This distinction is crucial for evaluating the feasibility and profitability of a mining project and making informed investment decisions.

What are the different types of mineral resources?

There are different types of mineral resources based on the level of geological knowledge and confidence, including inferred, indicated, and measured resources. Inferred resources have the lowest level of geological knowledge and confidence, while measured resources have the highest level of geological knowledge and confidence.

What are the different types of mineral reserves?

There are two main types of mineral reserves: proven reserves and probable reserves. Proven reserves have a high degree of geological confidence and are considered to be economically viable under current conditions. Probable reserves have a lower degree of geological confidence but are still considered to be economically viable under current conditions.
