Minerals 260 Starts Early Construction at Bullabulling Gold Project

15 June 2026 | Western Australia - Minerals 260 has commenced early construction and development activities at its 100%-owned Bullabulling Gold Project, located around 25km west of Coolgardie in Western Australia.

The start of early works marks a significant step toward the company’s target of beginning plant construction in the first half of CY2027 and achieving first gold production in the fourth quarter of CY2028.

Minerals 260 said work is now advancing across several areas, including accommodation village construction, water infrastructure and grade control drilling. The company received approval in May 2026 for its Mining Development and Closure Proposal and Works Approval for construction of a 400-person accommodation village.

In April, Minerals 260 awarded ATCO Structures & Logistics a $59.1 million fixed-price contract for the design and construction of the initial 400-person village. Site preparation and bulk earthworks are now underway, with the rooms and facilities being manufactured at ATCO’s Perth facility. The village is expected to be fully operational in the March quarter of 2027.

The company has also commenced drilling and installation of water bores to support construction and future operations. Water exploration has identified several potential sources, including palaeochannel and fractured rock systems.

Why it matters: Bullabulling is one of the larger gold development projects in Western Australia’s Eastern Goldfields, with a reported JORC 2012 Mineral Resource Estimate of 130Mt at 1.0g/t gold for 4.5Moz. The project is located on granted mining leases and sits within a broader tenement package of approximately 1,160km².

A grade control program has also commenced at the Phoenix deposit, involving 26,000m of 10m by 10m reverse circulation drilling. The drilling is focused on two high-priority areas expected to contribute to early years of production. Minerals 260 said it intends to use Photon Assay as the primary analytical method and is assessing the potential for an on-site Photon Assay facility.

The company said its maiden Ore Reserve and Pre-Feasibility Study remain on track for release in July 2026, with an updated Mineral Resource Estimate scheduled for August 2026.

Managing Director Luke McFadyen said the company was uniquely positioned to begin early construction before completion of the PFS, supported by preparatory work from the project team and a strategic funding agreement with Franco-Nevada. He described the start of early construction as another important de-risking milestone.

Minerals 260 said it remains well funded, with around $250 million in cash and deposits at the end of the March 2026 quarter.

For Western Australia’s mining sector, Bullabulling’s move into early construction points to a growing pipeline of gold development work, including accommodation, civil works, water infrastructure, drilling, approvals, future plant construction and operational readiness.
