Tools to Effectively Evaluate and Communicate the Potential Value of Mineral Projects


Abstract: There are hundreds of exploration companies that are actively marketing their mineral projects as future profitable mines. A few key metrics can highlight the intrinsic value of a given project. A dozen drill holes can be used to evaluate the exploration potential, in-situ value, geometrical/grade continuity, thickness, applicable mining/processing method and cost structure for a given prospect. Most projects, however, also contain an inherent challenge or technical difficulty that makes them uneconomic or unacceptable for investment. Quickly discovering what those are, and evaluating the potential impact to revenue, cost and implementation is the key to a successful project evaluation workflow; this exercise requires a diligent and multidisciplinary team. It is easy and safe to say that the project is worse than advertised, they mostly are. The difficult part is establishing whether the investment opportunity outweighs the technical risk.

Technical evaluations need to be staged to avoid spending too much time on aspects that are low risk or on projects that lack merit. Effective reporting tools are fundamental to the process. Decisions makers are often technically peripheral to mining; their objective is to understand the risk and potential reward of a given project. Reports therefore, must distill and translate the technical information into a succinct and visually impactful format to enable decision makers to quickly grasp the economic potential for the current stage of review, and make a call to advance or discard the opportunity.
