In the absence of drilling, indicative mineral resources can still be reported using various methods and standards. Here are some key points to consider.
- Geological Evidence: utilise geological mapping, sampling and geophysical surveys to gather data on the mineralisation. This information can help estimate the location, grade and quantity of the resource.
- Qualified Person: ensure that the resource estimates are carried out by a “Competent Person” or “Qualified Person” with significant experience in mineral exploration and assessment.
- Reporting Standards: follow internationally accepted reporting standards such as those set by the Committee for Mineral Reserves International Reporting Standards (CRIRSCO), the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) or the South African Code for Reporting of Mineral Resources and Mineral Reserves (SAMREC). These standards provide guidelines for classifying and reporting mineral resources.
- Indicated Resources: an “Indicated Resource” is a mineral resource whose quantity, grade, shape, size and continuity can be confidently reported based on geological evidence and sampling. This classification allows for preliminary economic viability and resource extraction calculations.
- Modifying Factors: consider modifying factors such as mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors when reporting the resource.
By adhering to these guidelines, you can provide a reliable estimate of indicative mineral resources even without drilling.
