British Hill high-grade gold extensions: drilling and lode geometry notes for engineers
Reviewed by Joe Ashwell
First reported on Australian Mining
30 Second Briefing
Strong reverse-circulation drilling results at Forrestania Resources’ British Hill project in Western Australia include 4m at 7.46g/t gold from 124m, with a 1m interval at 22.76g/t, and a separate 1m at 22.98g/t from 141m in hole 26BHRC013. The eight-hole RC programme targeted down-dip and along-strike extensions of previously defined mineralisation, confirming high-grade shoots at depths beyond 120m. These intercepts support potential resource growth and justify further step-out drilling and structural modelling of the lode geometry.
Technical Brief
- RC drilling configuration suits rapid coverage of structurally controlled lodes in hard Archaean greenstone terrane.
- High-grade down-dip hits suggest steeply plunging shoots, guiding future hole orientation and collar spacing.
- Depth of mineralisation (>120 m) points towards potential underground extraction scenarios rather than shallow open pits.
- Structural modelling will likely focus on shear-hosted lode geometry, vein continuity and potential flexures or jogs.
- Follow-up step-out drilling is expected to tighten drill spacing for maiden resource classification under JORC.
- Comparable Forrestania gold systems often require detailed geotechnical logging to manage variable rock mass and faulting.
Our Take
Forrestania Resources has been steadily consolidating Western Australian gold ground – with recent moves at MacPhersons, Newington and Hyden – so high‑grade hits at the British Hill project strengthen a multi‑asset exploration story rather than a single‑prospect bet.
The 7.46 g/t over 4 m and >22 g/t 1 m intervals at around 124–141 m depth sit in the range where open‑pit to underground transition strategies are commonly evaluated in Western Australia, which could give Forrestania optionality on future mine design if continuity is proven.
In our database of gold‑tagged project pieces, Forrestania now appears repeatedly alongside other WA explorers reporting strong intercepts, suggesting it is positioning itself as a more material regional player ahead of the proposed all‑scrip acquisition of Zenith Minerals announced in June 2026.
