From Assay to Answer: Unlocking Mineralogy from the Data You Already Own

Mining decisions are made on minerals, not elements.

About this event

Exploration teams have accumulated vast geochemical datasets over decades through capital-intensive drilling programs. Yet, much of this data remains underutilised— particularly for extracting mineralogical insight.

Modern analytical methods such as 4-acid ICP-MS mean assays are not merely indicators of grade; they encode mineralogical signatures that can be leveraged by geologists, mining engineers, geotechnical teams, and metallurgists. However, building robust mineralogical models still typically requires additional sampling, complex logistics, and costly specialised analyses such as qXRD, QEMSCAN, or core scanning.

In this webinar, Takeshy Coaquira and Scott Halley demonstrate how Comet applies advanced modelling techniques to assay data to infer mineralogical composition. This enables rapid extraction of mineralogical intelligence from legacy datasets, supporting more informed targeting, improved resource interpretation, and faster decision-making.

I am an exploration geologist and geochemist specialising in copper and gold systems, currently based in Australia. My work sits at the intersection of economic geology, geochemistry, and data-driven exploration to enhance the discovery and evaluation of mineral deposits.

Currently, I am the Lead Geochemist at Fleet Space Technologies, where I collaborate with Scott Halley on the COMET geochemical platform. My role focuses on integrating geochemical data, mineral chemistry, and geological models into scalable workflows that support target generation, vectoring, and decision-making across exploration portfolios.

Scott has consulted to more than 150 mining and exploration companies in more than 25 countries in the last fourteen years. Having worked as an exploration geologist for 20 years prior to specialising as a geochemist means that Scott understands how geochemistry can be practically and effectively applied to exploration and mining problems. Advances in technology mean that there are significant changes in the quality of commercially available geochemical and mineralogical analysis methods every few years. One of Scott’s aims is to ensure that his clients are using the most appropriate methods and deriving the full benefit from their data.
