Targeting
Historical records, geological maps and satellite data are used to pick the most promising ground.
Fieldwork
Mapping, soil and rock sampling and geophysical surveys narrow a target down to drill-ready zones.
Drilling
Drill holes test the target at depth, and core is logged and assayed by accredited laboratories.
Resource
Results are built into a mineral resource estimate reported to international standards.
Exploration is where most of the value in mining is created. A single discovery can support decades of production.
