Exploration license and proposed extensions

Satellite alteration mapping across the license and its neighbors, followed by ground magnetic and soil geochemistry surveys over the target areas. We reviewed the contractor's magnetic data as it came in, assessed adjoining blocks for acquisition, and wrote the remote sensing justification that went to the department with the extension application.

A whole-license remote sensing assessment

Multispectral and hyperspectral data combined with fault and lineament interpretation, mapped into dominant mineral groups and scored into follow-up areas. The report said plainly where the strongest responses were rock type rather than alteration, so the field budget went to the ground that deserved it.

Exploration blocks in glaciated terrain

Remote sensing reports and an interpreted litho-spectral map separating iron-oxide gossans from the metamorphic rocks between glaciers. Geological mapping followed, with a magnetic survey planned for terrain too steep for a regular grid: lines laid out along ridges and walkable slopes.

Targeting under forest and in high valleys

A targeting workflow for skarn and greisen: spectral classification, hyperspectral comparison with reference minerals, and vegetation-stress mapping where forest hides the rock. Results were ranked into follow-up areas inside and between licenses, then checked against field lithology.

River placer leases, from bulk samples to a plant

Bulk sampling along a river placer lease, with recovered gold mapped station by station and plotted downstream so the richer reaches stand out. The results fed the geological report for the department and a recovery plant flowsheet sized for local fabrication. Exploration plans, budgets and an investor proposal followed for further river leases.
