Ballard Mining Eyes Feasibility Study as Mt Ida Gold Resource Jumps 56% to 1.84 Moz
Key Takeaways
- Ballard Mining's Mt Ida Global Mineral Resource Estimate has grown 56% to 20.4 Mt @ 2.8 g/t for 1.84 Moz gold, adding 658 koz since the February 2026 update at a discovery cost of just $36/oz.
- Baldock, the cornerstone deposit, grew 35% to 1.36 Moz @ 3.5 g/t gold, while satellite deposits West Knell and Golden Vale surged 258% and 359% respectively, with three maiden MREs also delivered.
- Approximately 60,000 m of drilling completed after the MRE cut-off date and 40,000 assay results still pending from the laboratory represent a substantial pipeline of potential resource additions not yet captured in the current estimate.
- The company holds A$62M cash, all mineral resources on granted mining leases, and a Works Approval for a 2.0 Mtpa process plant — a permitting position that is genuinely rare for a developer at this stage.
- Management is targeting a 2 Moz MRE ahead of a Feasibility Study and Final Investment Decision, with a mid-CY2027 FID target and a board drawing on experience from De Grey Mining, Saracen, Ramelius, Gold Road, Gold Fields, and Newmont.
Mt Ida’s mineral resource crosses 1.84 Moz as Ballard Mining accelerates toward a feasibility study
In its September 2026 investor presentation, Ballard Mining (ASX: BM1) outlined a significant step forward at its Mt Ida Gold Project in Western Australia’s Eastern Goldfields. The Mt Ida Global Mineral Resource Estimate (MRE) has grown 56% to 20.4 Mt @ 2.8 g/t for 1.84 Moz gold, up from 1.178 Moz in the February 2026 update, a gain of 658 koz at a discovery cost of just $36/oz.
The presentation framed this growth within a “drill and build” strategy, with the company targeting a 2 Moz MRE ahead of a Feasibility Study and a Final Investment Decision (FID). With A$62M cash as at 30 June 2026 and a market capitalisation of A$350M, management presented the company as funded, permitted, and on a clear path to that milestone.

What the deposit-level numbers show
Baldock remains the cornerstone of the Mt Ida project, growing 35% to 1.36 Moz @ 3.5 g/t gold. The standout performers among the satellite deposits were West Knell, which grew 258% to 147 koz, and Golden Vale, which grew 359% to 124 koz. Three maiden MREs were also delivered: Neptune (27 koz), Pluto (27 koz), and Astro-Quasar (21 koz).
The update incorporated 125 km of RC (Reverse Circulation) and Diamond Drilling completed since the February 2026 MRE. The table below shows the full deposit-by-deposit comparison.
| Deposit | Feb 2026 MRE (koz) | Sep 2026 MRE (koz) | Increase (koz) | Increase (%) |
|---|---|---|---|---|
| Baldock | 1,006 | 1,363 | 357 | 35% |
| West Knell | 40 | 147 | 107 | 258% |
| Golden Vale | 27 | 124 | 97 | 359% |
| Jupiter | 11 | 29 | 18 | 164% |
| Neptune | — | 27 | 27 | n/a (maiden) |
| Pluto | — | 27 | 27 | n/a (maiden) |
| Astro-Quasar | — | 21 | 21 | n/a (maiden) |
| Other | 94 | 94 | — | n/a |
| Total MRE | 1,178 | 1,836 | 658 | 56% |
The MRE was prepared using a gold price assumption of A$4,500/oz, with an open pit cut-off grade of 0.5 g/t Au and underground cut-off grades of 1.3 and 1.5 g/t Au.
Why orogenic gold systems like Baldock run deep, and why that matters for investors
An orogenic gold deposit is one formed through tectonic processes, typically where ancient rocks have been squeezed, faulted, and intruded by hydrothermal fluids over millions of years. The critical characteristic for investors is depth: these systems often extend far below the surface, supporting long mine lives and significant resource expansion potential as drilling pushes deeper.
The presentation cited renowned structural geologist Dr Sarah Jones, who considers Mt Ida analogous to Gold Fields’ +10 Moz Agnew gold camp, noting the same large granite intrusion underpins both systems. Agnew, located approximately 150 km north, reaches 1.4 km depth. Ora Banda’s Riverina mine, approximately 80 km south on the same greenstone belt, is mineralised to more than 1 km depth.
Baldock currently extends to at least 600 m vertical depth across a 3.3 km strike length, with mineralisation also intersected a further 1.2 km south of the MRE along the Baldock Shear, for a total strike length of 4.5 km. Extensional targets, including Nebula Deeps, Meteor Deeps, and Baldock Deeps, are being drilled to 350–750 m depth in the current CY2026 programme, with a deeper programme targeting 750–1,000 m planned for CY2027.
Recent high-grade intercepts from drilling beyond the current MRE boundary include:
- BDG022: 8 m @ 7.7 g/t Au, including 2.3 m @ 20 g/t Au and 3.4 m @ 23.6 g/t Au
- LSEX002: 3 m @ 8.0 g/t Au
Beyond the MRE cut-off date of 30 June 2026, approximately 60,000 m of drilling has been completed and approximately 40,000 assay results (around 8 weeks of samples) remain pending from the laboratory. These results will be assessed in future MRE updates.

Funded, permitted, and on a clear path to FID
The presentation highlighted permitting as a fundamental competitive advantage for a gold developer at this stage. Key permits and approvals already in place include:
- All Mineral Resources on Granted Mining Leases
- Approved Mining Proposal and Mine Closure Plan for open pit and underground mining at Baldock
- Works Approval granted for a 2.0 Mtpa Process Plant and tailings storage facility
- Approved Native Vegetation Clearing Permit
- 3.7 GL/yr groundwater licence granted, with seven production bores installed
- Mt Ida public road diversion commenced and on schedule for completion within the December Quarter
The FY27 development roadmap presented by management maps a clear sequence toward FID:
- Sep Q 2026: 1.84 Moz MRE update complete; geotechnical studies, metallurgy, and process plant studies complete; water production bores complete
- Dec Q FY27 – Jun Q FY27: Growth drilling at Baldock and regional targets, targeting a 2 Moz MRE; infill drilling to convert Inferred Resources to Indicated Resources
- Dec Q FY27 – Mar Q FY27: Baldock dewatering bores; public road diversion completion
- Dec Q FY27 – Jun Q FY27: Feasibility Study (incorporating Maiden Ore Reserve), with completion targeted to align with the 2 Moz MRE
As stated in the presentation, the Final Investment Decision is contingent on the timing of scale addition arising from Baldock extensional and regional drilling and the completion of a Definitive Feasibility Study, with a mid-CY2027 target.
The corporate position supporting this roadmap includes A$62M cash, 454 million shares on issue, and a 24% institutional shareholder base. The board brings direct experience from De Grey Mining, Saracen, Ramelius, Gold Road, Gold Fields, and Newmont, providing operational depth across gold development and production cycles.
