Highlights

Barminco secured an approximately AUD 275 million Fourmile underground Mining contract in June 2026.
The agreed contract term is 45 months from 1 July 2026.
Planned work includes twin Bullion Hill portals and approximately 16 kilometres of development.
Barrick continued advanced studies and resource drilling at Fourmile during 2026.

Perenti Limited (ASX:PRN) provides mining services through businesses including the underground mining contractor Barminco. Its operations cover contract mining and related services in multiple jurisdictions. During 2026, Barminco secured a development contract at Barrick's Fourmile gold project in Nevada. More recent information from the project owner indicates continued studies and drilling, although those activities should not be mistaken for additional Barminco contracts.

Fourmile Contract Scope and Value

Perenti Limited (ASX:PRN) announced in June 2026 that Barminco had secured an underground development contract at Fourmile with an estimated value of AUD 275 million. The contract runs for 45 months from 1 July 2026. Work covered under the award includes development of the twin Bullion Hill access portals, ground support, surface facilities and associated mining services.

The disclosed scope incorporates approximately 16 kilometres of underground development. Perenti identified an estimated AUD 39 million of growth Capital required in FY27 for the contract. These are contract and capital estimates, not reported Revenue or profit earned to date. The amount eventually recognised will depend on the work performed and applicable contract accounting.

Position in Nevada Operations

Fourmile is located near Barrick’s Goldrush operation in Nevada. Barminco already provides services at Goldrush, giving Perenti Limited (ASX:PRN) an existing operating presence in the region. The separate Fourmile development award extends its activity to an adjacent project and requires equipment and workforce deployment aligned with a multi-year programme.

The June contract announcement identified the Bullion Hill access works as an early component of Fourmile development. Underground access can support subsequent drilling and engineering activity, but a development-services contract does not establish the timing or profitability of any future producing mine. Additional work scopes would need their own disclosures.

Barrick’s 2026 Project Update

Barrick’s third-quarter 2026 update confirmed that advanced Fourmile studies were continuing, incorporating resource drilling, metallurgical test work, geotechnical investigations and mine design. It described infill and resource-definition drilling as ongoing priorities. The status of these programmes is relevant to Perenti Limited (ASX:PRN) because development schedules depend partly on the owner’s study and access requirements.

However, Barrick’s broader portfolio guidance and other project milestones are not equivalent to new commercial commitments for Barminco. The Fourmile contract remains the specific disclosed basis for discussing Perenti’s participation. Neither the project-owner update nor the original award establishes a follow-on contract or a guaranteed extension.

Execution, Capital and Project Dependencies

Perenti Limited (ASX:PRN) must deliver development services while managing underground productivity, equipment use, safety, labour and cost exposure. The stated growth capital requirement creates an Investment commitment ahead of or during work execution. Revenue timing and margins may differ from the headline contract value depending on performance and contract terms.

Fourmile is still progressing technical studies, and future mine-development decisions belong to the project owner. Any changes in design, permitting, drilling schedules or capital allocation could alter the pace of contracted activity. For Perenti, the next useful evidence will be company reporting on contract progress, capital deployed and North American operating performance.

Key Insights

Perenti Limited (ASX:PRN) has a defined 45-month underground development contract at Fourmile, while Barrick continues technical work on the project. The contract broadens Barminco’s Nevada activities but does not guarantee further awards. Project scheduling, execution costs and the disclosed FY27 capital requirement are relevant to its delivery.
