Sentinel Metals Expands US Gold Footprint with $26M Big Springs Acquisition

Sentinel Metals Nearly Doubles US Gold Resources

Sentinel Metals Limited (ASX:SNM) is making a decisive leap in the North American gold space by agreeing to acquire the Big Springs Gold Project in Nevada from Capricorn Metals Limited (ASX:CMM) for up to $26 million. This transaction, combining $8.5 million cash, $5 million in Sentinel shares, and up to $12.5 million in contingent milestone payments, will boost Sentinel’s combined Mineral Resource base to approximately 2 million ounces of gold across two advanced projects in Tier-1 US mining jurisdictions.

Big Springs: A Permitted, High-Grade Nevada Asset

Big Springs carries a JORC-compliant Mineral Resource Estimate (MRE) of 15.5 million tonnes grading 2.0 grams per tonne gold for 1.01 million ounces. The project is fully permitted for both open pit and underground mining, a rare advantage that positions Sentinel for potential near-term production. Historically, Big Springs produced around 386,000 ounces of gold from seven open pits between 1987 and 1993, underscoring its proven mining credentials.

The project lies within Nevada’s prolific Independence Trend, adjacent to First Majestic Silver Corp’s Jerritt Canyon mine and mill. While Sentinel has no current processing agreements with First Majestic, the proximity to three regional roasters offers strategic optionality for future ore processing.

Exploration Upside and Growth Pipeline

Sentinel is eyeing significant exploration upside at Big Springs, with drill-ready targets within the existing Mining Lease and high-grade underground ore shoots that remain open at depth. Historical drill intercepts include standout hits like 17.7 metres at 33.4 grams per tonne gold, highlighting the potential to expand the resource rapidly.

Beyond the current resource, the project encompasses a substantial 93 square kilometre landholding of underexplored Carlin-style gold tenure, adjacent to major Nevada gold systems. Sentinel intends to conduct an approximately 10,000-metre drilling program targeting resource growth and new discoveries.

Funding the Acquisition and Advancing Columbia

To fund the acquisition and ongoing exploration at both Big Springs and Sentinel’s flagship Columbia Gold-Silver Project in Montana, the company is raising $15 million through a placement priced at $0.58 per share. Capricorn plans to participate in the capital raising with a $3 million subscription. Completion of the acquisition and placement is contingent on shareholder approval and other customary conditions.

Sentinel’s Managing Director Matt Herbert emphasised the strategic fit: “Big Springs delivers an additional large scale, advanced gold asset in a Tier-1 jurisdiction with potential near-term production optionality and a pipeline of exploration and development opportunities that we believe can create significant long-term value for Sentinel shareholders.” Meanwhile, drilling at Columbia continues as planned, with first assay results expected in approximately six weeks.

Milestone-Linked Contingent Consideration

The deal includes contingent payments of $6.5 million and $6 million payable upon the announcement of resource milestones of 1.5 million ounces and 2.0 million ounces respectively, or upon divestment of the project at specified valuations within two years. Sentinel may elect to pay these tranches in cash, shares, or a combination, subject to shareholder approval.

This structure aligns payments with value creation, but also introduces some uncertainty depending on future exploration success and market conditions.
