BMG’s Bullabulling Project comprises an extensive area in the Coolgardie region, an established gold mining district of Western Australia located approximately 70km from Kalgoorlie.
In 2025, Minerals 260 Limited (ASX: Mi6) announced it was acquiring the Bullabulling Gold Mine owned by the privately held Norton Gold Fields Pty Ltd, which is majority owned by China’s largest gold producer – Zijin Mining Group Co., Ltd. Consideration payable by Mi6 for this acquisition is A$156.5 million cash and A$10 million in Mi6 shares.
The Bullabulling Gold Mine is located approximately 1.5km from BMG’s Bullabulling Project with several BMG tenements immediately adjacent to the western portion of the Bullabulling Gold Mine’s tenure.
The Mineral Resource Estimate at the Bullabulling Gold Mine is reported to contain a JORC compliant mineral resource of 130M t @ 1g/t Au for 4.5Moz Au as well as on-site infrastructure.
The exploration and development work proposed by Mi6 at the Bullabulling Gold Mine promises to re-invigorate this part of the Coolgardie region, creating a new focus on BMG’s exploration activities at its 100% owned Bullabulling Project.
The Project is near established infrastructure, including water, power, gas and road networks. The major supply route to the Goldfields, the Great Eastern Highway, crosses BMG’s tenement package.

BMG’s tenure at Bullabulling comprises three areas – Bullabulling West, Bullabulling North and Bullabulling East; see Figure 2 below. The north-south oriented gold trend that hosts the Bullabulling Gold Mine and multiple other gold occurrences is interpreted to extend into BMG’s Bullabulling North area.
The Bullabulling West and East blocks are interpreted to host greenstones that may have potential to host gold mineralisation.

Mi6 has reported very impressive drill results at its Bullabulling Gold Mine which are described as extending gold mineralisation and being open towards the west; see ASX Release by Mi6 dated 7 July 2025 ‘Bullabulling Gold Project – Drilling Update’ (the “Mi6 Announcement”).
BMG has reviewed and interpreted the Mi6 drill results and believes that a number of the high-grade gold intercepts have potential to continue into BMG’s Bullabulling West area which abuts Mi6 ground. There is potential for continuity of the mineralisation identified at the Bullabulling Gold Mine to extend into BMG’s 100%-owned tenure.
The gold mineralisation at the Bullabulling Gold Mine occurs in stacked gold lodes; see the Mi6 Announcement. The gold lodes commence at or near surface and dip shallowly towards the west (40 to 50 degrees).
BMG has identified greenstones at its Bullabulling West area which abuts the western border of the Bullabulling Gold Mine tenure. This prospective stratigraphy has potential to host gold mineralisation and BMG will prioritise exploration for potential repetition at Bullabulling West of similar stacked gold lodes that are present at Mi6’s ground.
BMG’s exploration success:
Reconnaissance drilling at Bullabulling North has returned several near-surface intercepts of high-grade gold warranting further exploration to scope out the potential for significant mineralisation.
Significant intersections from historical drilling and recent reconnaissance drilling are shown below.
Historical shallow RAB drilling at BMG’s tenure has returned:
- 5m @ 2.5g/t Au from 36m
- 2m @ 5.7g/t from 49m
- 1m @ 3.02g/t Au from 37m, and
- 2m @ 1.71g/t Au from 41m
Recent drilling by BMG has also intersected high-grade gold including:
- 4m @ 2.37g/t Au from 53m
- 2m @ 18.1 g/t Au from 34m
- 1m @ 10.6 g/t Au from 58m, and
- 4m @ 10.12 g/t Au from 32m
The mafic-ultramafic stratigraphy that hosts the multi-million ounce Bullabulling Gold Mine is interpreted to extend into BMG’s ground, providing strong encouragement for the potential of significant gold mineralisation at BMG’s project. This potential is already supported by the presence of high-grade gold confirmed by drilling.
A gold focussed drilling and exploration programme is being designed by BMG for 2026 to further scope the gold potential at its 100% owned Bullabulling Project.
