• Great Boulder secures $5 million via a strategic placement
• Placement led by leading Australian resource fund Tribeca Investment Partners
• Funds to accelerate exploration at the Side Well Gold Project

Great Boulder Resources Limited (ASX:GBR) has announced that it has received binding commitments to raise $5 million via a strategic placement. The placement will comprise the issue of approximately 74 million new fully paid ordinary shares at an issue price of 6.75 cents per share. The placement was driven by strong interest from leading institutional investors, led by Tribeca Investment Partners, a leading Australian resource fund. The issue price represents an 8.8% discount to Great Boulder's last close on 24 September 2025. The funds raised will be used to accelerate the company's exploration program at the Side Well Gold Project, where a Mineral Resource of 7.45Mt @ 2.8g/t Au for 668,000oz Au has been defined. Great Boulder's Managing Director, Andrew Paterson, commented that the placement is a further step change for the company as leading global institutional investors acknowledge its significant growth potential. The placement, combined with the company's existing cash reserves of around $12 million, positions Great Boulder well to deliver on its goals of defining one million ounces of gold as a short-term target and advancing its early mining opportunity at Ironbark while building its resource base for the next stage of growth.

Great Boulder is well positioned for future success with a portfolio of highly prospective gold and base metals assets in Western Australia, a strong technical team, and the backing of leading institutional investors. The company expects a strong pipeline of news flow throughout the remainder of 2025 and 2026 with three rigs now drilling at the Side Well Gold Project and a fourth rig due to arrive soon.
