Supplementary materials for Logged geological groups guide prediction review in sparse-drilling mineral exploration: graphite and gold drillholes

Supplementary materials accompanying the manuscript Logged geological groups guide prediction review in sparse-drilling mineral exploration: graphite and gold drillholes. Online Resource 1 (ESM_1.pdf): supplementary methods, aggregate evidence and diagnostic tables. Online Resource 2 (ESM_2.zip): screened executable code, fixed configurations, public-input source records and reference outputs for the independent Canadian validation. Online Resource 3 (ESM_3.zip): aggregate-only Tanga evaluation, geological-group, width-ranking, benchmark, strata and calibration diagnostics, including reproduction and hash records. The Tanzanian source data remain confidential. Protected coordinates, private interval records, source rasters and private reports are excluded. The Canadian application is locally refitted and does not establish universal transfer. These materials report research analyses and make no mineral-resource, reserve, economic or mine-design claim.
