As stakeholders in the mineral industry, we are certainly familiar with the term “mineral resources.” The spoon we use for eating, the laptop and computer we work with, and even the handle and lock installed on our doors — all are products derived from mineral resources, particularly metallic minerals.
According to SNI-4726, mineral resources are defined as a concentration or occurrence of materials with economic value on or above the Earth’s crust, possessing a specific form, quality, and quantity with reasonable prospects for eventual economic extraction.
So, what about mineral reserves? Mineral reserves refer to mineral deposits whose size, shape, distribution, quality, and quantity are already known, and which can be mined economically, technically, legally, environmentally, and socially at the time the evaluation is conducted.
