Key Highlights

Downhole geophysical survey at Baldock identifies a major conductor extending to 1,100 metres below surface, 485 metres below the base of the current 1.36Moz Baldock gold MRE.
High-grade assay results outside the current Baldock MRE include 1.2m at 20.9g/t Au from 775.8m and 0.35m at 41.8g/t Au from 319.6m.
Shallow results at regional prospects Ayla and Vortex include 7m at 2.5g/t Au from 99m and 3m at 4.5g/t Au from 69m, both outside current resource estimates.
Total Mt Ida Mineral Resource was updated to 1.84Moz in a prior announcement dated 23 September 2026, with current drilling targeting growth beyond that estimate.

Mt Ida's Resource Potential Extends Well Beyond Current Estimates

Ballard Mining (ASX:BM1) has delivered a drilling update that raises fundamental questions about the ceiling of the Mt Ida Gold Project's resource potential, with new results returning high-grade gold intersections beyond the footprint of the current Mineral Resource Estimate at Baldock while downhole geophysics points to a mineralised system that could extend to depths not yet tested.

The ASX announcement of 28 October 2026 focuses on growth drilling across multiple deposits at Mt Ida, situated 540 kilometres northeast of Perth in the Western Australian Goldfields. The project covers 26 kilometres of prospective Greenstone belt and was the subject of a September 2026 MRE update that lifted total resources to 1.84 million ounces across the project.

Baldock: Depth and Grade Beyond the Current Model

At the Baldock deposit, which hosts 1.36Moz of the total Mt Ida MRE, a downhole geophysical survey has identified a major conductor extending to a vertical depth of 1,100 metres — 485 metres below the base of the current resource model. This is a material discovery from a geophysical programme, suggesting that the mineralised system feeding Baldock is significantly larger than what has been captured in the existing resource.

Assay results from drilling outside the current Baldock MRE boundary reinforce the geophysical findings. The most significant intersections include 1.2 metres at 20.9g/t gold from 775.8 metres depth in hole BDG009 and 0.35 metres at 41.8g/t gold from 319.6 metres in BDG022W1. Additional high-grade hits outside the MRE include 1.1m at 11.1g/t from 868.9m, 1.5m at 13.4g/t from 425.6m, and 1.4m at 7.5g/t from 765.5m. While intercept widths are narrow, the grades and depths involved signal that Baldock's mineralised system has not been closed off at depth.

Regional Prospects Add Breadth to the Growth Story

Beyond Baldock, growth drilling at regional prospects has returned shallow, broader intersections across multiple targets. At Ayla (West Knell), results include 7m at 2.5g/t gold from 99m and 3m at 4.5g/t from 69m. At Vortex, the programme returned 4m at 2.5g/t from 36m and 5m at 1.7g/t from 16m. The Astro-Quasar deposit delivered 1m at 11.9g/t from 37m, while at Sandstone, 9m at 1.0g/t from 48m was recorded.

These results collectively demonstrate that multiple systems across Mt Ida's 26-kilometre Greenstone belt remain open and are returning mineralised intercepts outside the current resource boundaries. MD Paul Brennan noted that the results strengthen confidence in continued Mineral Resource growth across the project.

Geological Interpretation and Follow-Up

Geological modelling incorporating the new geophysical data and assay results is underway. The downhole conductor at Baldock is described as a major find that warrants follow-up drilling to test the extent of mineralisation at depths that may add substantially to the resource base. The new information is being assessed for incorporation into future Mineral Resource updates.

Sector Context

Mt Ida occupies a well-regarded position within Western Australia's Goldfields, a region that continues to attract exploration and development Capital due to its proven geological setting and established infrastructure. The progression from a 1.36Moz Baldock deposit to a geophysically defined conductor extending 485m deeper represents a meaningful increase in the scale of the system being explored. At the regional scale, the combination of high-grade deep targets at Baldock and broad shallow mineralisation across Ayla, Vortex, and Astro-Quasar creates a multi-front growth story.

Risks

The geophysical conductor at Baldock requires drill testing to confirm whether it represents economic gold mineralisation — geophysical anomalies do not always translate to resource-grade intersections. Narrow high-grade intercepts at depth are technically challenging to mine and may not contribute materially to resource Economics without additional bulk-tonnage mineralisation nearby. Deeper drilling is also more capital-intensive, and Ballard will need to balance its exploration budget across multiple active targets.

Resource growth from regional prospects such as Ayla and Vortex is dependent on follow-up drilling confirming the continuity and grade of shallow intercepts across sufficient strike length to meet resource threshold requirements.

What to Watch Next

The primary near-term focus is follow-up drilling below the Baldock MRE to test the 1,100-metre conductor identified by geophysics. Any drill intersection at depth confirming gold mineralisation in that zone would represent a potentially significant resource growth event. Investors should also track the progress of geological modelling incorporating the latest datasets, and watch for announcements of an updated MRE that incorporates the growth results now in hand from Baldock and the regional prospects.
