- Porphyry Copper-Gold Exploration: Surveys extensive hydrothermal alteration systems in northern Queensland using induced polarization geophysics and structural mapping to guide deep diamond drilling programs targeting high-tonnage, intrusive-related copper-gold mineralization.
- Epithermal Silver and Gold Targeting: Undertakes surface rock chip sampling, trenching, and high-resolution geophysical surveys across prospective mineral tenement acreage to define shallow epithermal gold and silver drill targets adjacent to established regional mining operations.
