The upcoming campaign is the largest coordinated drill programme initiated by the company at Madison and is designed to systematically extend and expand on shallower high-grade copper and gold mineralisation, and test deeper porphyry discovery targets.
For the RC portion, the company has engaged O'Keefe Drilling based in Butte, Montana. For the diamond core portion of the programme, the company has engaged Nasco Industrial Services and Supply LLC (“NISS”), on behalf of itself or its wholly-owned subsidiary, NISS Drilling Services LLC based in Kellogg, Idaho.
Utilising both RC and diamond drilling methods will optimise costs, improve efficiency, and accelerate target testing across multiple zones. RC drilling will be used for rapid, cost-effective testing of near-surface skarn targets and to establish precollars for deeper core hole tails, while diamond drilling will focus on testing high-priority porphyry targets at depth.
The programme is designed to test two complementary opportunities: expansion of known copper-gold skarn mineralisation near surface and potential discovery of a larger intrusive-related copper-gold porphyry source at depth. Recent technical work supports the interpretation that Madison represents a broader evolving mineralised system than historically recognised.
The programme will test up to eight of the highest-priority skarn and porphyry targets that represent the most informed drill targets ever defined at the project.
These targets are the culmination of extensive technical work that has integrated:
- Detailed geological and structural mapping.
- Re-interpretation of historical drilling and surface geochemistry.
- High-resolution geophysics.
- Advanced 3D modelling and data analytics.
