BLACKROCK SILVER ENGAGES GLOBAL FRONTIER ADVISORS TO ADVANCE U.S. CRITICAL MINERALS STRATEGY AT TONOPAH WEST

Blackrock Silver Corp. has engaged Global Frontier Advisors LP (GFA), a strategic advisory firm (based in Washington, D.C.) whose partners include former senior U.S. military officers, diplomats and international business executives in the pursuit of federal and state support, non-dilutive capital, and tax incentives programs that have followed silver's November, 2025, designation as a U.S. critical mineral.

Under the engagement, GFA will support Blackrock in identifying and pursuing non-dilutive government funding, procurement and financing pathways for which its 100-per-cent-owned Tonopah West silver-gold project, located in the Walker Lane trend of west-central Nevada, may be eligible. As an emerging developer of a high-grade domestic primary silver asset, Blackrock is positioning Tonopah West as a strategically significant contributor to a secure, U.S.-based silver supply chain.

Tonopah West is one of the highest-grade undeveloped primary silver projects of size in the world. Blackrock believes the project has the potential to increase domestic U.S. silver production by approximately 10 per cent throughout its 11-year mine life, delivering a consistent, meaningful contribution to domestic supply from a rare long-life primary silver asset. The company anticipates breaking ground on underground development in 2027, with an aim to commence test mining and a large-scale bulk sample in 2028. Situated directly adjacent to the town of Tonopah, the historic Queen of the Silver Camps, with U.S. Highway 95 crossing the property, Tonopah West benefits from established infrastructure, a skilled regional work force, private land tenure, and one of the world's most stable and mining-supportive jurisdictions.

Andrew Pollard, president and chief executive officer of Blackrock, commented: "Silver is a critical input to solar energy, defence systems and the technologies driving America's industrial future, and yet the United States still imports the majority of what it consumes. Tonopah West is exactly the kind of high-grade, domestic project that can help close that gap. We're leaving no stone unturned in pursuing the federal and state support available to us, giving us the potential to move faster and more efficiently to bring Tonopah West on line and start delivering benefits for all of our stakeholders. Engaging Global Frontier Advisors is central to that effort, giving us the ability to navigate D.C. with credibility that resonates within the national security, energy and development finance communities."

Commenting on behalf of GFA, Lt.-Gen. David Bellon, USMC (retired), managing partner of Global Frontier Advisors, said: "The United States holds no silver in strategic reserve and produces a fraction of what it consumes, with much of the balance imported from abroad. In recognizing this vulnerability and designating silver a critical mineral, Washington took a crucial first step toward supply chain resilience -- but what matters now is acting on it. Tonopah West is that opportunity. A high-grade domestic source of this scale has the potential to lift U.S. silver production by roughly 10 per cent and meaningfully reduce our reliance on foreign imports. We're excited to work alongside the Blackrock team to align Tonopah West with the federal and state programs built for precisely this moment."

Through the GFA engagement, Blackrock intends to pursue funding and procurement pathways for which Tonopah West may be eligible. These could potentially include programs administered under the Defense Production Act and those available through the U.S. Department of Energy, the Export-Import Bank of the United States and the U.S. International Development Finance Corp., among others, as well as state-level incentives and tax credits available in Nevada.
