Forrestania lifts WA British Hill gold resource past 210,000 ounces

Forrestania Resources has delivered a solid 21 per cent increase to its British Hill gold resource, lifting the deposit’s total inventory to 212,400 ounces as it assembles the building blocks for a major two-hub gold production business in Western Australia.

The updated mineral resource estimate for the project now stands at 4.12 million tonnes grading 1.6 grams per tonne (g/t) gold for a total of 212,400 ounces using a 0.5g/t gold cutoff. Notably, the update includes a significant 37 per cent increase in the higher-confidence indicated resource category, which now accounts for 138,100 ounces, or about two-thirds of the total deposit.

The upgrade incorporated results from 15 holes of an ongoing 3685 metre reverse-circulation drilling campaign, which has already served up one hole with an eye-catching 59-metre intersection grading 2.38g/t gold from 123m. Three RC rigs and one diamond rig are still turning rods at the project, focused on extending mineralisation along strike and down-dip.

Within the project’s global resource, a recently landed British Hill prefeasibility study also points to a maiden ore reserve at British Hill of 1.56 million tonnes at 1.43g/t gold for 71,900 ounces, capable of generating A$104.8 million in pre-tax free cash flow for a restart capital of just $16.1M.

The expanding ounce-count is expected to feed directly into Forrestania’s ambitious strategy of creating a significant West Australian gold production business powered by two key processing hubs, the 2.9-million-tonne-per-annum Edna May plant and the 3.2-million-tonne-per-annum Lake Johnston facility.

Forrestania Resources chairman David Geraghty said: “This updated Mineral Resource Estimate, released just one month after the previous estimate, represents another important milestone in the growth of the British Hill Mineral Resource. This update not only materially expands the gold inventory at British Hill but also delivers a significant increase in higher-confidence Indicated Mineral Resources, which now comprise more than half of the total contained gold ounces.”

The company is running a textbook hub-and-spoke playbook, consolidating a portfolio of satellite gold deposits to funnel ore to its soon-to-be operating mills. This approach allows Forrestania to potentially fast-track development, avoiding the significant capital and time required to construct new processing plants from scratch.

Anchoring the company’s ambitions is the Edna May project, where a recent prefeasibility study outlined a robust 10-year operation. The study defined an ore reserve of 12.6 million tonnes at 0.99g/t gold for 402,800 ounces and projected it could spin off a hefty $728.7 million in pre-tax free cash flow across the mine’s decade-long life.
