Transforming Great Boulder’s Gold Portfolio
Great Boulder Resources (ASX:GBR) is making a bold move to cement its standing in Western Australia’s Murchison goldfields by acquiring the Peak Hill Gold Project from Westgold Resources (ASX:WGX) for $25 million in cash, a 19.9% equity stake, and a 1% net smelter royalty. This deal adds a substantial 481,000 ounces of JORC 2012-compliant gold resources, complementing Great Boulder’s existing Side Well Gold Project, which boasts over 1 million ounces of gold resources nearby.
The acquisition is more than just a resource boost; it’s a strategic pivot towards near-term, capital-light production. Great Boulder has inked an Ore Purchase Agreement to process Peak Hill ore at Westgold’s three regional mills, Bluebird, Fortnum, and Tuckabianna, leveraging established infrastructure to accelerate production timelines.
Westgold’s decision to take a significant shareholding and nominate a board representative underscores confidence in Great Boulder’s technical and operational capabilities. This partnership also includes a non-binding strategic collaboration aimed at fast-tracking the Side Well Gold Project, located just 25km from Westgold’s Bluebird Mill, potentially unlocking operational synergies and cost efficiencies.
Robust Capital Raising to Fuel Aggressive Drilling
Concurrent with the acquisition, Great Boulder is raising $40 million through a two-tranche placement priced at 8.5 cents per share, slightly discounted to recent trading levels. The funds will underpin a substantial 60,000-metre, multi-rig drilling campaign across both Peak Hill and Side Well over the next six months, targeting resource validation, infill, and extensions to the current mineralisation.
Following completion, Great Boulder expects a pro-forma net cash position of $25 million, positioning the company to rapidly advance pre-production activities. The appointment of Chris Tuckwell, former MD of mining contractor MACA Limited, as Chair signals a focus on operational readiness and mining execution.
Peak Hill’s Rich History and Exploration Upside
Peak Hill is a historically high-grade gold camp with over 900,000 ounces mined previously, including four open pit mines and seven granted mining leases spanning 106 square kilometres. The project hosts five main deposits, Five Ways, Durack, Enigma, Harmony, and Jubilee, with a combined resource of 9.4 million tonnes at 1.6 grams per tonne gold for 481,000 ounces.
Great Boulder’s technical team sees significant upside potential. Recent drilling by Westgold in 2025 returned impressive high-grade intercepts in the Treasure area, such as 19 metres at 13.34 g/t gold and 10 metres at 18.79 g/t gold, indicating promising brownfields targets beyond the current resource base. This aligns with the company’s plans for intensive infill and extensional drilling to update the Mineral Resource Estimate within six months.
The project’s proximity to Westgold’s mills and Great Boulder’s Side Well Gold Project creates a compelling regional hub for gold production. The strategic collaboration aims to capitalise on shared infrastructure, contractor networks, and logistical efficiencies, potentially accelerating production and enhancing cash flow generation.
Ore Purchase Agreement Details and Production Pathway
The Ore Purchase Agreement sets out delivery of ore to Westgold’s Bluebird, Fortnum, and Tuckabianna mills within 18 months post-acquisition, with minimum and maximum monthly tonnages specified for each mill. Pricing is tied to recoverable gold content minus processing costs, margins, and state royalties, with Great Boulder responsible for ore delivery costs.
This arrangement offers Great Boulder a capital-light route to production, sidestepping the need for immediate mill construction or heavy upfront capital expenditure. The company aspires to achieve “mining-ready” status for Peak Hill within 12 months, though this remains aspirational pending further drilling and economic studies.
Next Steps and Market Implications
With shareholder approval anticipated in mid-June 2026, Great Boulder’s acquisition and placement completion will be pivotal milestones. The upcoming drilling results and resource updates will be closely watched, as they will shape the project’s development trajectory and valuation.
Westgold’s recent financial strength, highlighted by its robust cash position and expansion plans at Higginsville, provides a stable backdrop for this collaboration. The deal also follows Westgold’s strategic divestments and capital raises earlier in the year, reflecting a focus on core assets and operational partnerships.
Great Boulder’s aggressive push into resource growth and near-term production, backed by experienced leadership and a strong capital base, positions it as a rising player in WA’s gold sector. However, the aspirational nature of mining readiness and reliance on shareholder approvals introduce execution risks that investors should monitor.
Overall, the Peak Hill acquisition is a significant step for Great Boulder, potentially transforming its scale and operational profile while leveraging Westgold’s infrastructure and expertise.
Given the strategic nature of this deal and the scale of planned drilling, the market will be keen to see how Great Boulder balances exploration success with advancing towards production milestones, especially in the context of Westgold’s ongoing growth initiatives such as the Higginsville Expansion and its strong cash build.
Investors should also consider the implications of Westgold’s capital management moves, including its recent $600M unsecured facility that underpin its capacity to support partnerships like this.
Bottom Line?
Great Boulder’s Peak Hill acquisition stakes a claim in a historically rich gold district with near-term production potential, but execution hinges on drilling success and shareholder approvals.
Questions in the middle?
- Will Great Boulder’s 60,000m drilling campaign unlock significant resource upgrades at Peak Hill?
- How effectively can the Ore Purchase Agreement accelerate capital-light production timelines?
- What operational synergies will emerge from the strategic collaboration with Westgold at Side Well?
