Junior explorer CGT protection push: funding and project risk lens for engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Australian mining bodies are urging the Federal Government to extend capital gains tax (CGT) concessions to junior mineral explorers, matching relief already available to tech and other start-up sectors. The Minerals Council of Australia and the Association of Mining and Exploration Companies warn proposed CGT changes could deter high-risk greenfields exploration, particularly for early-stage ASX-listed juniors reliant on equity raisings. Industry groups argue that without tailored CGT treatment, pre-discovery investors may exit earlier and reduce funding for drilling campaigns and resource definition.
Technical Brief
- Proposed CGT settings directly affect pre-discovery equity raisings that fund early drilling metres and geophysics.
- Policy concern centres on greenfields programs where drilling success probabilities and time-to-discovery are lowest.
- Industry groups emphasise that exploration capital is typically recycled rapidly between successive grassroots campaigns.
- CGT treatment is being compared with existing concessions already granted to software, biotech and other start-ups.
- Investor behaviour modelling used by lobby groups assumes shorter holding periods typical of speculative exploration stocks.
- AMEC and MCA argue that CGT settings should recognise the binary value step-change at first economic discovery.
- For other high-risk resource projects, similar CGT asymmetry could shift capital towards brownfields or near-production assets.
Our Take
Capital gains tax settings for junior explorers in Australia sit alongside a dense stream of regulatory coverage in our database (123 Policy stories), signalling that fiscal terms are becoming as material to project pipelines as environmental and heritage approvals.
The involvement of both the Minerals Council of Australia and AMEC suggests alignment between major and junior ends of the sector, which typically gives Canberra fewer excuses to delay or dilute tax reforms affecting early‑stage projects.
With Australian Mining also driving coverage of record iron ore revenues at Fortescue, any CGT concessions for juniors are likely to be framed politically as recycling windfall gains from established producers into higher‑risk greenfields exploration rather than as a net giveaway.
