Great Boulder Resources has just unveiled a whopping 4,434g/t gold assay at its Side Well Gold Project in Western Australia. The company already has a 1 million ounce resource and has outlined a plan to increase this to 1.5 million ounces, located right on the edge of three processing plants.

Andrew Paterson is the Managing Director of Great Boulder Resources. He is a geologist with more than 25 years of experience in the mining industry, spanning exploration, resource development and project generation across Australia and internationally. Prior to joining Great Boulder, he held senior roles with several exploration and mining companies where he was responsible for discovery and advancement of gold projects in Western Australia. At Great Boulder, he is leading the company’s exploration and development strategy at the Side Well Gold Project near Meekatharra.

1. Exceptional High-Grade Assay Highlights Depth Potential Great Boulder recently reported an extraordinary 4,434g/t gold intercept at the Side Well Gold Project, one of the highest-grade hits recorded in the industry this year. While extremely high-grade zones are typically small, they demonstrate the presence of rich gold-bearing structures at depth and reinforce the potential for continued discovery beneath the existing resource. These “bonanza” zones occur in structural dilation points where coarse gold accumulates.

2. A 2.5km Resource Corridor With Potential to Become a Regional Super Pit The current resource extends across approximately 2.5 kilometres of strike between the Mulga Bill and Eaglehawk deposits. With only a narrow gap of limited drilling between the two areas, upcoming drilling programs aim to confirm continuity that could effectively link the deposits into a single large open pit system. At current gold prices, conceptual pit optimisations already suggest a large combined mining footprint.

3. Targeting Growth From 1Moz to 1.5Moz Resource Great Boulder currently hosts a 1 million ounce resource at Side Well, with roughly 62% in the indicated category. The company’s next strategic objective is to increase the total resource to around 1.5 million ounces, which could translate to roughly 1 million ounces of mineable inventory after studies and conversions. Achieving that scale would significantly enhance development and partnership options.

4. Strategic Location Near Multiple Processing Mills A major advantage for the project is its proximity to several operating or proposed processing facilities in the Meekatharra region. Within trucking distance are three potential mills, including Westgold’s Bluebird facility only about 25km away. This infrastructure access creates multiple potential development pathways, including toll treatment or acquisition interest from nearby operators seeking additional feedstock.

5. Accelerated Drilling and Development Pathway Underway Great Boulder is ramping up exploration with multiple drilling rigs targeting both resource expansion and new discoveries around the existing corridor. The company is simultaneously advancing mining leases, approvals and development studies to shorten the timeline from exploration success to production readiness. As resource growth and permitting progress in parallel, the project could become increasingly attractive to strategic partners or regional consolidators.

Minerals 260 (ASX: MI6) has had a stunning ten months since acquiring the Bullabulling Gold Project in Western Australia. The stock has soared on the back of its exploration success and its recent funding deal.

Rapid Resource Growth at Bullabulling Minerals 260 has rapidly expanded the Bullabulling Gold Project to a resource of approximately 4.5 million ounces, including around 3 million ounces in the indicated category. Located just 45 minutes from Kalgoorlie in Western Australia, the project has quickly emerged as one of the more significant undeveloped gold assets on the ASX.

A Transformational Acquisition The company acquired Bullabulling for around $166 million, and in less than a year the market has re-rated the company dramatically as exploration success and development progress have strengthened the investment case. This rapid value creation reflects both the scale of the asset and strong investor demand for large gold development projects.

Franco-Nevada Deal Provides Validation and Funding Minerals 260 secured a $120 million royalty funding package with Franco-Nevada, one of the world’s largest precious metals royalty companies. The deal followed extensive technical due diligence and provides development capital while reducing near-term dilution, representing a major validation event for the project.

Large-Scale Open Pit Development Potential Current planning outlines a potential 4–5km long open pit, approximately 600 metres wide and 300 metres deep, positioning Bullabulling as one of Australia’s largest future gold pits. Ongoing drilling is focused on improving project economics by targeting shallower and higher-grade mineralisation.

Fast-Tracked Path to Development Minerals 260 is progressing rapidly toward development, with reserve work, resource updates and feasibility studies advancing through 2026. Early site infrastructure work — including accommodation and water infrastructure — is already underway ahead of a final investment decision, reflecting strong confidence in the project’s economics and the supportive gold macro environment.
