INTEGRATED APPROACH
From regional screening to field evidence and target ranking.
For early-stage exploration, HASH can connect remote sensing, geological field checks, sampling, laboratory QA/QC and target ranking into a structured decision chain.
Remote Sensing
Lineament, drainage, alteration proxy, access and land cover.
Geology Field Check
Lithology, structure, alteration, quartz vein, float and outcrop.
Sampling
Stream/pan, rock-chip, float and selected channel or soil sampling.
Assay & QA/QC
Laboratory analysis supported by blanks, duplicates and reference material.
Target Ranking
Integrated evidence for Go / Hold / Stop and the next budget gate.
