A project acquired today typically comes with work by several previous explorers: annual technical reports to the regulator, open-file data from the geological survey, drill logs typed or handwritten, assay certificates from laboratories that no longer exist, and maps in local grids. The information that would change a drilling programme is often in there. Reading it all by hand takes a geologist months.
AI mineral exploration support, as we build it, is mostly careful extraction. Collar coordinates with their datum, hole depths and orientations, lithology and alteration intervals, assay results with their laboratory and method, and the QA/QC that came with them. Each value goes into a structured table with a citation, so the geologist can check any figure in a click and trust none of them blindly.
