Genesis Minerals executive chair Raleigh Finlayson has raised concerns that changes to capital gains tax could discourage investment in junior explorers, potentially weakening Australia’s future mineral discovery pipeline at a time when established gold producers are enjoying substantial margins.
Speaking at the Melbourne Mining Club, Finlayson questioned whether the Federal Government had adequately considered the consequences of reducing potential after-tax returns for investors taking on the considerable risks associated with early-stage mineral exploration.
His comments highlight a growing divide within Australia’s resources sector: established producers have the cash flow to fund exploration and acquisitions, while junior explorers remain heavily dependent on external capital to advance discoveries.
For investors, the concern is whether changes to the risk-reward equation could redirect capital away from exploration, ultimately reducing the pool of development opportunities available to the next generation of Australian mining companies.
“It’s very difficult down the curve at the moment,” Finlayson said.
“And one of the massive frustrations I’ve got on exploration is the government’s proposed changes to capital gains tax, which is going to disincentivize mum and dad and retail investors to be investing into the gold space, which is our lifeblood.”
Finlayson said the issue extended beyond gold, with insufficient funding for new discoveries potentially affecting every commodity.
The exploration funding equation
At a media briefing following his Melbourne Mining Club appearance, Finlayson expanded on the investment implications.
Junior exploration companies typically operate without production revenue, relying on equity raisings to fund drilling and geological programs. Investors accept substantial uncertainty in exchange for the possibility of significant returns if a commercially viable discovery is made.
Finlayson argued that changes to capital gains tax could alter that calculation.
“So if you’re going to invest a dollar in there, it’s hard enough to get a return at the best of times, but when you do, previously under the old regime, you get a 50 per cent discount on the capital gains,” he said.
“What the government’s effectively doing is capping the upside.”
His concern is that investors would retain the same exposure to unsuccessful exploration programs while potentially receiving less of the financial benefit from successful investments.
That could have particular implications for retail investors and high-net-worth individuals, who play a significant role in financing junior exploration.
“If that starts to flow through, exploration companies are funded from retail investors, not institutions,” Finlayson said.
“So, where’s the start of that pipeline being funded?”
The potential consequences extend beyond individual capital raisings.
If investors demand higher prospective returns to compensate for reduced tax benefits, junior explorers could face more expensive equity funding, greater dilution or reduced access to capital altogether.
Companies with established resources, strong drilling results or strategic investors may remain attractive, while earlier-stage explorers with less defined prospects could find it increasingly difficult to secure funding.
For ASX investors, that raises the possibility of a more selective exploration market, with capital concentrating in advanced projects rather than being distributed across higher-risk greenfields opportunities.
The industry case for exploration incentives
Finlayson’s concerns align with those of the Minerals Council of Australia (MCA), which has criticised the Federal Government’s capital gains tax changes for excluding junior minerals explorers from concessions available to certain types of tech start-ups.
The MCA argues that early-stage exploration carries risks comparable to venture capital investment and should receive similar tax treatment.
Its analysis suggests the changes could reduce investors’ after-tax capital gains returns from junior exploration investments by at least 19 per cent.
(The estimate is the MCA’s assessment of the proposed tax arrangements, rather than a demonstrated reduction in investor returns.)
The industry body has also criticised the decision to axe the Junior Minerals Exploration Incentive, arguing that reduced incentives could further constrain funding for greenfields exploration.
According to the MCA, greenfields expenditure has fallen from approximately one-third of total Australian exploration spending in recent years to one-quarter in the latest financial year.
A shift away from greenfields investment could leave Australia increasingly reliant on expanding known deposits rather than generating new discoveries across not only gold but also critical minerals and other commodities requiring substantial new resource development.
Why consolidation cannot replace discovery
Finlayson’s comments carry particular weight given his record of building gold businesses through acquisitions and operational integration.
At Saracen Mineral Holdings, he helped transform a junior explorer into a major producer before its merger with Northern Star Resources.
Since joining Genesis Minerals in 2021, he has pursued a strategy of consolidating neighbouring assets across Western Australia’s Leonora district.
Genesis’ proposed merger with Vault Minerals could create a gold producer delivering approximately 600,000–700,000 ounces annually, with around $2 billion in forecast post-tax synergies over the next decade.
However, Finlayson also highlighted the limitations of relying on consolidation to sustain industry growth.
Mining companies continually deplete their reserves through production, while future discoveries are becoming deeper, more technically challenging and increasingly expensive.
He pointed to Gold Fields’ approach to Northern Star as another example of the consolidation activity reshaping the Australian gold sector.
“The fact that Gold Fields has come out after Northern Star at the moment really surprises me,” Finlayson said.
For investors, the distinction is important.
Acquisitions can transfer reserves between companies and create operational efficiencies, but they do not necessarily increase the industry’s overall mineral inventory.
If new discoveries fail to keep pace with depletion, established producers could face increasing competition for development-ready assets.
That could support the strategic value of advanced projects with substantial resources, particularly those located near existing processing infrastructure.
At the same time, a shrinking exploration pipeline would eventually limit the opportunities available for acquisition.
The widening funding divide
Finlayson drew a distinction between Genesis’ ability to fund its own exploration and the position facing junior companies.
Established producers benefiting from strong gold prices can allocate operating cash flow towards drilling, development studies and resource replacement without depending on successive equity raisings.
Junior explorers have no equivalent financial buffer.
Although elevated gold prices can improve investor sentiment and encourage capital raisings, Finlayson noted that exploration funding has historically been highly cyclical.
His concern is that changes to capital gains tax could amplify that volatility when commodity prices retreat or market appetite weakens.
The result could be a widening funding divide between established producers, advanced developers and early-stage explorers.
For investors, this creates several potential consequences.
Companies with strong balance sheets and internally funded exploration programs may gain a competitive advantage, while juniors with substantial resources and credible development pathways could become more attractive to strategic investors.
Conversely, earlier-stage explorers could face greater dilution, reduced drilling activity or longer timelines between exploration campaigns.
The availability of funding may increasingly determine which geological opportunities progress, rather than geological merit alone.
It could also increase the importance of joint ventures, cornerstone investments and corporate transactions as alternative funding sources.
What investors should watch
The immediate test will be whether changes to capital gains tax materially affect participation in junior exploration capital raisings.
Retail investor demand, placement pricing and the ability of early-stage companies to fund drilling programs will provide indications of whether the sector’s concerns are translating into market behaviour.
Another measure will be the balance between greenfields and brownfields exploration expenditure.
If investment continues to favour existing deposits, Australia’s future project pipeline could become increasingly concentrated around established mining districts.
That would have implications for producers seeking reserve replacement, developers competing for funding and investors assessing the long-term scarcity value of advanced mineral assets.
The consequences would not necessarily emerge quickly.
Discoveries can take many years to become operating mines, meaning reduced exploration activity today may only become apparent in future production and development opportunities.
Finlayson’s central argument is that the industry’s current profitability should not obscure the need to finance its next generation of discoveries.
For investors, the broader question is whether Australia’s exploration sector will retain sufficient access to risk capital to replenish the resources being mined today.
Strong gold prices and consolidation can create considerable value across the established producer market.
But without sustained investment at the earliest stages of exploration, the number of assets available for future development and acquisition could diminish.
That makes the availability and cost of exploration capital an increasingly important consideration in assessing the long-term outlook for Australian resources equities.
