Regional-scale portfolio prediction













Images from Hronsky and Groves, 2008.

Minerals exploration is a high-risk venture when most effort is focused on individual prospects at only kilometre scale. Knowledge about how the prospect compares with genetically related deposits, in terms of resource size and commercial viability, is often not sought. The result is often descriptive, rather than comparative.

Trying to predict the future outcome of an exploration program, or trying to envisage what Nature did millions of years ago and kilometers below surface, requires a risk-based forecasting approach to rocks and regions.

Desktop asset evaluations and exploration probability of success predictions can add more value and reputational kudos than the drill bit, especially during periods of low commodity price, cost reduction, efficiency drives or COVID-19 restrictions.

Minerals exploration can benefit a different approach, like the one the petroleum industry adopted when Play-Based Exploration techniques became widely accepted and used. Petroleum explorers invest effort to predict, understand and map the prospect portfolio at regional scales before selecting countries and license blocks to enter: geological and economic uncertainties, risks and chances of success. Why? To enable informed decision-making and Risk Management across a portfolio. It is a cost-effective approach: 1 regional-scale exploration team + data + evaluations across 3 countries = a fraction of the cost of 1 misplaced drilling programme. The approach has impressed investors.

Play-Based Exploration enabled exploration companies to predict where petroleum system components overlap geographically: revealing the most fertile regions for petroleum discovery. A merge of predictive exploration targeting and Play-Based Exploration techniques could be the paradigm shift required for mineral exploration. Route To Reserves can bring this to your organisation.

Rewards for regional scale exploration assessments and targeting.


• Strong foundation for confident greenfield and brownfield exploration.

• Uncertainties, risks and probability of success mapped: smarter Risk Management and where to direct your budgets.

• Metrics for geoscientists, economists and strategists to use together.

• Objective, scaled results to build an exploration targeting strategy.

• Increased chance of success and decision quality.

• Competitive advantage for evaluating and risking a region’s licenses.


All cheaper than 1 misplaced drilling campaign
