Aurumin Ltd Advances Sandstone Gold Project Development Strategy

Streamlining Portfolio to Focus on Core Gold Assets

Aurumin Limited (ASX: AUN) has executed a series of binding transactions to divest all non-core assets, raising $6 million in cash to accelerate development of its flagship Sandstone Gold Project. The strategic move aligns with the company's focus on advancing toward gold production in Western Australia's prolific Sandstone region.

The divestment encompasses multiple transactions with Newcam Minerals, Yilgarn Iron, and Sierra Mining and Exploration, allowing Aurumin to prioritise exploration and development activities at Sandstone without shareholder dilution.

"Signing these binding transactions provide a pathway for Aurumin to be well funded for exploration activities through and beyond completion of the Scheme of Arrangement with Brightstar. These divestments allow Aurumin to focus on the gold opportunities at Sandstone and also unlock value from the non-gold assets," said Managing Director Daniel Raihani.

Deal Structure: Maximising Value from Non-Core Assets

The company has structured a comprehensive series of transactions to divest assets that don't align with its core Sandstone gold strategy:

Accelerating Sandstone Gold Project Development

The proceeds will enable Aurumin to immediately commence drilling and exploration activities designed to:

• Increase resource confidence classification across multiple deposits including Shillington, Two Mile Hill, McIntyre, and Plum Pudding
• Advance the Aurumin Ltd Sandstone Gold Project simultaneously with Brightstar's Pre-Feasibility Study
• Ensure all deposits in the consolidated Sandstone Project are incorporated within the pro forma PFS

This funding arrives at a critical time for Aurumin, with the company aiming to rapidly advance its Sandstone Gold Project, which hosts a substantial 885,800-ounce gold Mineral Resource across multiple deposits.

Understanding Mineral Rights Agreements

For investors new to the mining sector, understanding mineral rights agreements is crucial when evaluating this transaction.

What are mineral rights agreements?

These legal arrangements separate ownership rights for different minerals within the same land area. In Aurumin's case, the company is retaining gold and silver rights while selling rights to other minerals like iron ore.

This structure allows Aurumin to maintain focus on gold exploration and development while monetising other mineral potential on their tenements. By dividing these rights, the company creates value from assets that might otherwise remain unexplored while concentrating capital and expertise on their primary gold targets.

Strategic Partners Enhancing Value

The divestment brings in established mining partners with specific expertise in different mineral sectors:

Newcam Minerals is a private company with multiple mineral portfolios including gold and iron ore assets in Western Australia's Mid-West region. With its own drilling and mining fleet, Newcam has successfully developed and operated the Mt Gould Iron Ore mine through to export.

Yilgarn Iron aims to rejuvenate the Yilgarn Iron hub, beginning with restarting operations at the Koolyanobbing Ore Handling Plant by the end of 2025. The company is reportedly well-funded and committed to exploration and resource development.

Sierra Mining and Exploration is a private group focused on mineral resource projects with near-term development potential in Western Australia.

Timeline and Development Path

With funding secured from these divestments, Aurumin can now execute a clearly defined development strategy:

• Immediate commencement of drilling programs at key Sandstone deposits
• Resource classification upgrades to advance project confidence
• Integration with Brightstar's Pre-Feasibility Study for the consolidated Sandstone Project
• Pathway toward production decision with strengthened financial position

All transactions are expected to complete by mid-October 2025, providing Aurumin with immediate capital to deploy toward its core asset.

Aurumin Ltd Sandstone Gold Project: The Crown Jewel

The Sandstone Gold Project represents Aurumin's primary focus going forward, with impressive statistics that highlight its potential:

• 950,500 ounce total gold resource across Sandstone Operations
• Multiple high-grade deposits including Two Mile Hill Underground (554,100oz at 1.6g/t)
• Established infrastructure and expanding tenement footprint
• Located in a historically productive gold region of Western Australia

The project comprises both open-pit and underground opportunities, with significant exploration upside across multiple targets.

Why Investors Should Watch Aurumin

This strategic divestment positions Aurumin Ltd Sandstone Gold Project as a focused gold developer with several compelling investment attributes:

1. Simplified asset portfolio concentrated on high-value gold resources
2. Strengthened balance sheet with $6 million in non-dilutive funding
3. Clear development pathway toward potential production
4. Strategic alignment with Brightstar's development plans
5. Retained royalty interests in divested assets providing potential future upside

For investors seeking exposure to Western Australian gold development stories, Aurumin presents a streamlined investment case with near-term catalysts and a strengthened financial position.

The company's decisive move to focus capital and management attention on its core Aurumin Ltd Sandstone Gold Project demonstrates a disciplined approach to creating shareholder value, with multiple exploration and development milestones expected in the coming months.
