Ballard’s Pluto prospect extension: design and targeting notes for mine planners
Reviewed by Tom Sullivan
First reported on Australian Mining
30 Second Briefing
Ballard Mining has extended the Pluto prospect at its Mt Ida gold project in Western Australia with new intercepts including 5m at 10.2g/t gold from 98m, 7m at 3.7g/t from 19m and 1m at high grade over narrower width north of the Baldock deposit. The results confirm shallow mineralisation from 19m downhole and deeper high-grade zones near 100m, supporting both open-pit and potential underground targeting. For mine planners and resource geologists, the data justify tighter step-out drilling and updated block models around Pluto’s northern extensions.
Technical Brief
- Pluto prospect lies immediately north of the existing Baldock gold deposit within the Mt Ida project.
- Mt Ida project is located in Western Australia, within an established Archean greenstone gold belt.
- Ballard Mining is operator and owner of the Mt Ida gold project and associated Pluto prospect.
- Recent drilling is part of an ongoing extensional programme targeting strike and depth continuity at Pluto.
- Step-out drilling north of Baldock is designed to test for repeat lodes parallel to existing mineralisation.
- Shallow intercepts suggest potential for low-strip-ratio oxide or transitional material near surface.
- Deeper intercepts around 100 m downhole align with typical starting depths for decline-access underground stopes.
- For comparable Western Australian greenstone projects, such high-grade shoots often control stope sequencing and ventilation design.
Our Take
Ballard Mining’s earlier lift of Baldock to a 1Moz resource in Western Australia suggests that new high-grade Pluto intercepts at Mt Ida are more about growing a district-scale gold camp than proving standalone viability.
The shallow 7m at 3.7g/t from 19m at Pluto points to open-pittable potential, which could complement deeper underground-style hits and improve project economics by blending ore types across the Mt Ida gold project.
Across the 1187 Mining stories in our coverage, only a subset of gold pieces report +10g/t intervals at similar depths, indicating Pluto’s 5m at 10.2g/t from 98m places Mt Ida in the upper tier of current Australian exploration results for grade.
