Lady Ida’s Iguana exploration round-up: structural insights for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Exploration updates across Australia include new drilling at Beacon Minerals’ Lady Ida gold project, where recent RC and diamond holes are targeting extensions to the Iguana lode along previously under-tested shear zones. Junior explorers are also advancing greenfields copper and critical minerals programs in Western Australia and Queensland, with step-out drilling and downhole geophysics refining targets around existing JORC resources. For geotechs and mine planners, the focus is on defining continuity, grade distribution and structural controls to justify follow-up infill drilling and potential resource upgrades.
Technical Brief
- Step-out drilling is being laid out on pre-set fences to test down-dip and along-strike continuity.
- Downhole geophysics is being run post-drilling to refine structural interpretations around existing JORC envelopes.
- Greenfields programmes are sequencing RC first for rapid coverage, with follow-up diamond tails in key structural positions.
- Data from new campaigns are being integrated into 3D models to constrain lode geometry before committing to infill grids.
- For similar brownfields shear-hosted systems, the approach underlines the value of early structural-geophysical integration.
