Pilbara Gold Limited (ASX:PGL) has been among the ASX gold explorers commanding attention in September 2026, as an aggressive drilling campaign at its Mt York project in Western Australia continues to add scale. With a growing resource, a pre-feasibility study underway and multiple rigs turning, Pilbara Gold has positioned Mt York as a potential major development story in the West Pilbara. The steady flow of drilling results has kept the stock featuring among active resource names as investors weigh the project's expanding potential.

Latest Developments

Pilbara Gold has been running a large drilling program at Mt York, adding a sixth rig as it pushed the project toward a pre-feasibility study. The company reported extending mineralisation as its drilling program reached the halfway mark, including intercepts below the existing pit shell that point to further depth potential. One update highlighted a broad gold intercept extending mineralisation beneath the current pit outline, reinforcing the case for a larger deposit. Alongside Mt York, Pilbara Gold commenced a 12,000-metre drilling push at its Roe Hills project, targeting a Western Australian gold corridor and broadening its exploration footprint. The company has presented its resource and study progress at industry roadshows during 2026, underlining its ambition to grow Mt York into a significant Western Australian gold development.

What Could Come Next

Near-term catalysts include further Mt York drill results, potential resource updates and progress on the pre-feasibility study. Success at Roe Hills could open a second growth front. Investors will look for the PFS to define production scale, costs and Capital requirements, which will be key to assessing Mt York's economic potential. Continued extensions to mineralisation, particularly at depth, could support a larger resource in future updates.

Risks to Watch

As a pre-production developer, Pilbara Gold faces the usual risks of moving a project through feasibility to construction, including funding, permitting and cost inflation. Study outcomes may differ from current expectations, and resource estimates can change with further drilling. The company relies on Capital Markets to fund its programs, raising the prospect of future dilution. Gold price Volatility directly affects project Economics and sentiment toward gold developers.

Conclusion

Pilbara Gold enters the final months of 2026 with a 2.1-million-ounce Mt York resource, an active multi-rig drilling program and a pre-feasibility study underway, keeping it among the ASX gold stocks under watch. Delivery of study milestones and continued drilling success will be pivotal, with the PFS set to test whether Mt York can advance toward its stated development ambitions.
