- Nittetsu Mining board approves transaction to earn 80% interest in Oracle Ridge JV
- Nittetsu to invest US$20 million over four years covering project costs and debt repayment
- Eagle Mountain free-carried until Nittetsu’s contributions reach US$20 million

- Renegotiated Vincere loan to be extinguished as part of the JV funding package
Strategic Partnership Advances Oracle Ridge
Eagle Mountain Mining Limited (ASX:EM2) has taken a significant step forward in realising value from its flagship Oracle Ridge copper-gold project in Arizona, USA. The company announced that the board of Nittetsu Mining Co., a mid-tier Japanese mining and smelting firm, has approved a transaction to earn an 80% interest in the Oracle Ridge project via a joint venture. This endorsement follows a non-binding indicative offer received in November 2025 and sets the stage for binding agreements expected to be signed in April 2026.
A $30 Million Commitment to Development
Under the terms of the proposed joint venture, Nittetsu will contribute US$20 million (approximately A$30 million) over four years towards all project expenditures. This includes funding to exercise an option agreement to re-acquire the Oracle Ridge mine from Marble Mountain Ventures LLC, and to extinguish Eagle Mountain’s outstanding US$7.25 million loan with Vincere Resource Holdings LLC at a discounted repayment of US$2.5 million. Eagle Mountain will remain free-carried until Nittetsu’s contributions reach the US$20 million milestone, after which it may choose to maintain its 20% interest by contributing proportionally or face dilution.
Unlocking a Significant Mineral Resource
The Oracle Ridge project boasts a substantial mineral resource estimate of 28.2 million tonnes grading 1.35% copper, 11.06 grams per tonne silver, and 0.16 grams per tonne gold. This equates to approximately 380,000 tonnes of copper, 10 million ounces of silver, and 142,000 ounces of gold. The project’s location in Arizona places it in the heart of the United States’ mining industry, near some of the world’s largest copper deposits, enhancing its strategic importance.
Financial and Operational Implications
The transaction not only provides Eagle Mountain with a clear pathway to develop Oracle Ridge but also addresses its financial liabilities by renegotiating and potentially extinguishing the Vincere loan at a significant discount. Nittetsu’s involvement brings a partner with extensive experience in mining and smelting operations across Japan and Chile, potentially accelerating project development and enhancing operational expertise.
Looking Ahead
With binding agreements anticipated in the coming weeks, the partnership with Nittetsu marks a pivotal moment for Eagle Mountain. The company’s executive director, Fabio Vergara, highlighted the milestone as a confirmation of Nittetsu’s commitment and expressed optimism about progressing the project collaboratively. Investors and industry watchers will be keen to see how this JV shapes the future of Oracle Ridge and Eagle Mountain’s position in the copper-gold sector.
Bottom Line?
The Nittetsu joint venture approval signals a new chapter for Oracle Ridge, but execution risks and dilution remain key watchpoints.
Questions in the middle?
- Will binding agreements be signed on schedule in April 2026, and under what final terms?
- How will Eagle Mountain manage dilution risk if it opts not to contribute beyond the free-carried phase?
- What is Nittetsu’s strategic plan for advancing Oracle Ridge towards commercial production?
