Gold and lithium explorer BMG Resources Limited (ASX: BMG) (BMG or Company) is pleased to announce a maiden Mineral Resource of 11.12Mt @ 1.45 g/t Au for 518koz Au for the Capital Deposit, part of its Abercromby Gold Project in the Wiluna-Agnew region of Western Australia.
HIGHLIGHTS
- Major Abercromby Project milestone with maiden Mineral Resource for Capital Deposit of 11.1Mt @ 1.45 g/t Au for 518koz Au (0.4g/t and 1.25g/t cut-offs for open pit and underground zones respectively)
- Open Pit area: 354koz @ 1.17g/t Au (>0.4g/t Au between surface and 200mbs)
- Underground area: 164koz @ 3.09g/t Au (>1.25g/t Au between 200 and 500mbs)
- 353koz (68%) Au Indicated and 165koz (32%) Au Inferred (using resource constraint above)
- 345koz in oxide and transitional material, 173koz in fresh material
- Higher grade component of the resource is 430koz @ 2.01g/t Au at a 1.0g/t lower cut-off
- Low $8.35/oz discovery cost
- Abercromby is on granted mining leases providing an expedited pathway to mining approvals
- Capital Deposit has open pit potential, with mineralisation starting from near surface extending at depth and along strike beyond Mineral Resource footprint
The maiden Mineral Resource, combined with metallurgical work that confirmed the orebody as free milling across all zones1, is a strong indicator of the potential for a straight-forward open-pit mining operation.
BMG will now commence development studies alongside high-impact expansion drilling to further convert Inferred resources to the higher-confidence Indicated category. BMG is also preparing for further exploration activities across the Abercromby Project area to test large regional gold anomalies to the south, which could deliver further Capital-style discoveries.
BMG Resources Managing Director Bruce McCracken said:
“This large maiden Mineral Resource at Abercromby, delivered at a discovery cost of just $8.35 per ounce, is a step-change in value for BMG. Through efficient use of exploration spend across three major drilling campaigns, BMG has shifted from pure explorer to potential developer with a large resource base and huge potential for further growth.
“Abercromby now has a metric for valuation that BMG can use to quantitatively demonstrate to the market its success in leveraging value from the drill bit.
“Abercrombyiswelllocatedfordevelopment.Thepotentialto monetise the project in a rapidly appreciating gold price environment, underpinned by this maiden resource for the Capital Deposit, places BMG in an enviable position as we continue to pursue sustained, long-term shareholder value.”
The Abercromby Gold Project
The Abercromby Gold Project is located on the Wiluna Greenstone Belt, one of Western Australia’s most significant gold-producing regions with a gold endowment of +40Moz Au – second only to Kalgoorlie globally in terms of historic production.
The geology at Abercromby is favourable for gold mineralisation, with drilling having intersected multiple thick intervals of high-grade gold mineralisation confirming the presence of a large, high-grade gold system. BMG holds 100% of Abercromby, which comprises the gold and other mineral rights (ex-uranium) of two granted mining leases (M53/1095 and M53/336). The mining leases provide for an expedited development pathway for the Company to secure mining approval.
Since acquiring the project in mid-2020, BMG has completed three reverse circulation and diamond drill programs primarily targeting the high-priority Capital Deposit. The Capital Deposit sits within the northern third of Abercromby’s 12km2 project area.
In parallel to the drill program, BMG has completed metallurgical test work on core samples from the Capital Deposit which confirmed its free-milling status and therefore amenability to conventional carbon-in-leach (CIL) processing, with high gold recoveries achieved. See our ASX announcement dated 6 February 2023 “High Gold Recoveries – Abercromby Metallurgical Test” for full discovery of the outcomes of the metallurgical test work.

The Mineral Resource estimation at the Capital Deposit was completed by ordinary kriging within 3D-modelled mineralisation wireframes and block modelling in Surpac, utilising a comprehensive data set generated by recent work undertaken by BMG as well as work completed by previous owners.
