Borealis Mining Announces Updated NI 43-101 Preliminary Economic Assessment for the Sandman Gold Project Highlighting Strong Stand-Alone Economics, ADR-Enabled Capital Efficiency and Substantial Leverage to Gold Prices
Nevada producer transitions from stockpile leaching to full-scale mining with a massive valuation boost from Sandman PEA

The most recent news (February 19, 2026) reports the results of an updated Preliminary Economic Assessment (PEA) for the Sandman Gold Project in Nevada. Using a base-case gold price of US$2,600/oz, the study outlines a 9-year mine life producing 38,000 oz Au annually. Key financials include a post-tax NPV (6%) of US$203 million and an IRR of 105%. Initial capital is estimated at US$36 million, benefiting from the ability to process loaded carbon at Borealis’s existing ADR facility. This update follows a month of high-intensity operational news, including the first production blast at the Borealis Mine (January 29, 2026) and the closing of a C$23 million bought deal financing (January 15, 2026).
The news is Material - Positive for three reasons: - Value Creation: Management has effectively demonstrated that the Sandman project, acquired for roughly C$8.9 million in March 2025, now carries an NPV (US$203M) that exceeds the company's current market capitalization. - Synergy Validation: The PEA confirms the strategic logic of the Gold Bull acquisition by utilizing Borealis's existing ADR infrastructure to keep initial CapEx low (US$36M), a rarity for a project of this scale. - Operational Derisking: The company has successfully raised C$23 million at C$1.50/share, providing the "dry powder" needed to bridge the gap between current stockpile leaching and full-scale mine production at the Borealis Mine, which saw its first blast in January.
While the PEA is preliminary and includes inferred resources, the 105% IRR provides a massive margin of safety against potential cost overruns or gold price volatility.
Borealis Mining Company Limited is a Nevada-focused gold producer. Its flagship is the Borealis Gold Mine, a fully permitted and built site near Hawthorne, NV, which has historically produced over 600,000 oz Au. The company is currently transitioning from leaching historic stockpiles to restarting open-pit mining. The secondary flagship is the Sandman Project (acquired 2025), a high-IRR development project intended to feed the Borealis ADR plant.
