In today’s sustainability driven landscape, recognising when a project has reached its limit is key. The discovery push recently has largely been driven by the need to supply raw materials to sustainable technologies. As the first stage of the discovery process, exploration should aim to also be as sustainable as possible.
Exploring more efficiently, not just more intensively, should be on the minds of exploration geologists. The recent increase in exploration budgets and aggressive programmes by some major mining companies has not correlated with discoveries. The data output related to these types of programmes can be massive and requires effective management allowing for on-the-fly interpretation to assist decision making. Recently, SRK has assisted clients in Egypt and Saudi Arabia by interpreting large volumes of data using advanced software. Prior to this, the geologist should have a good understanding of the geological context, and drafting cross-sections at the rig based on what comes out the ground will always have its place. Continuous updates to interpretations assist target prioritisation.
Exploration is dynamic. The ability to be flexible during programmes can prepare the company for changes in geological interpretation, budget, timescales and ESG commitments, each affecting target priority. Blanket drilling programmes are less effective, and for the most part should be avoided in early-stage projects. SRK has recently been in Cameroon assisting with drill programme development and reinforcing the importance for the geologist to be at the rig, maximising the drill programme and being prepared to stop holes in full consideration of the geological interpretation.
Persisting with low-probability projects drains the motivation and budget that should be allocated to explore in other potentially more prospective areas. The phrase ‘keeping the rigs turning’ is often unsustainable in an exploration context. Targets should be managed using clear decision points at the end of each exploration stage e.g., 1) continue to next phase of exploration, 2) conduct more exploration at that stage for further understanding, and 3) drop and move to another target. Dropping a target or project is not negative, it opens up the chance to focus efforts elsewhere.
In present exploration environments, efficiency, flexibility, and clear decision-making are essential. By integrating decision points and adapting to what we see on the ground, explorers can focus resources where they matter most. Sustainability in exploration lies not just in discovery, but in knowing when to move on.
