Hycroft Mining Advances Underground Development, Adds Two Drill Rigs

Hycroft Mining Holding Corporation (NASDAQ: HYMC) has detailed progress on its underground development projects at the Brimstone and Vortex high-grade systems in Winnemucca, Nevada, alongside plans to accelerate exploration through additional drilling rigs. The company is finalizing an internal assessment of underground mining alternatives, engaging RESPEC Company LLC to evaluate mine design and potential exploration declines, and Hatch Ltd. to assess processing options for gold and silver recovery. Concurrently, metallurgical testing at Hazen Research Inc. characterizes the ore’s response to processing, with roasting and pressure oxidation options under review—roasting could unlock additional revenue via sulfuric acid production. The reverse circulation drill program, launched in late 2025, has defined oxide and transition material characteristics, while two additional core rigs are expected in the fourth quarter to expedite drilling on Vortex and Brimstone, as well as other targets. The company also announced a refreshed brand identity and redesigned website (hycroftmining.com) to support its technical and operational updates.
