Overview
The Republic project is an exploration-stage asset held by Hecla Mining Company. The company's website lists Republic as an exploration project for gold. A 2022 company filing with the SEC also lists the Republic mining district in Washington state as one of its project areas. Recent company disclosures regarding exploration activities have not provided specific updates on the Republic project. In February 2026, Hecla announced it would nearly double its exploration and pre-development budget to $55 million for 2026. However, the stated focus for this increased expenditure is on projects in Nevada and its producing assets at Greens Creek (Alaska), Keno Hill (Yukon Territory), and Lucky Friday (Idaho), with no mention of the Republic project. Hecla's 2025 exploration focus noted a $22 million budget, but did not specify an allocation for the Republic project. The associated, nearby Knob Hill mine, which Hecla acquired in 1981 and operated until its closure in 1995, is listed by the Washington State Department of Ecology as "Awaiting Cleanup". Hecla has dismantled the mill and many administrative buildings and continues with long-term water management and treatment at the Knob Hill site.

It is part of Hecla Mining Company's Nevada Operations, which also include the Fire Creek, Midas, and Aurora mines. As of early 2026, the Nevada Operations remain on care and maintenance. Production at the Hollister mine was suspended in the third quarter of 2019. Hecla's strategic focus for its Nevada properties, including Hollister, is on exploration. The company has highlighted the potential of its Nevada portfolio as a high-impact development project with near-term production potential. The pre-existing infrastructure at Hollister and its location within hauling distance of Hecla's Midas mill are considered advantageous for the development of any new discoveries, avoiding the need for a new mill on-site.
Production
There has been no production at the Hollister mine since operations were suspended in 2019.
Expansion
Hecla Mining Company significantly increased its exploration and pre-development budget for 2026 to $55 million, with a substantial portion allocated to its Nevada projects, including Hollister. The company's exploration efforts are focused on the Hatter Graben vein system, which is described as having a known inferred resource containing 141,600 ounces of gold and 1,251,700 ounces of silver. The grades for this resource are reported at 0.38 oz/ton for gold and 3.4 oz/ton for silver, with the mineralization open for expansion. These resource figures are as of 31 December 2025. A March 2026 company presentation indicated a potential development decision for a restart of the Midas mine by 2029-2030, which could create a processing hub for ore from other Nevada properties like Hollister. State and federal approvals for waste rock and underground water management are required for the development of the Hatter Graben or other potential expansions at Hollister.
