Sunshine Silver Mining & Refining Co. is accelerating infrastructure upgrades in Big Creek, aiming to resume silver production at the historic Sunshine Mine by late 2028. As reported by cdapress.com, the company has invested heavily in modernizing equipment and expanding its workforce, signaling a significant shift for one of Idaho’s most iconic mining operations after more than two decades without sustained output.
Modernizing Historic Infrastructure
The Sunshine Mine, discovered in the 1880s, produced over 360 million ounces of silver during its operational history. The last period of sustained production ended in 2001, followed by a brief and unsuccessful restart attempt in December 2008 and January 2009. Since then, the site has remained largely inactive while ownership groups evaluated the viability of reopening.
Recent months have seen substantial physical changes to the mine yard. The historic mill is currently being deconstructed to make way for a modern replacement facility. Additionally, a new portal is under development on the south end of the property, designed to provide access and ventilation for upper underground workings.
A major milestone was reached in May when the company replaced the 1916 Nordberg double-drum hoist at the Jewell Shaft. The multimillion-dollar project installed a new Seimag-Techberg double-drum hoist along with a secondary egress hoist, enhancing both operational capacity and safety protocols. Refurbishment of the Silver Summit hoist and shaft is scheduled to begin in 2027.
Feasibility Studies and Financial Planning
Nick Furlin, operations and technical services manager at Sunshine Mine, noted that investor confidence has grown as data collection progressed. “Once enough information was obtained, the investor group made the decision to push forward with beginning the final feasibility studies and making return-to-production plans,” Furlin told the Coeur d’Alene Press.
The company is currently conducting three major feasibility studies covering the mine and mill operations, an antimony plant, and a silver refinery. These studies are expected to be completed in 2027, providing the detailed financial and technical data necessary for long-term planning. Current projections indicate a mine life of approximately 23 years if production resumes as scheduled.
To support these capital-intensive projects, Sunshine Silver Mining pursued an initial public offering (IPO) to raise funds amid improving market conditions for precious metals. The move underscores the company’s commitment to securing the financial resources needed for a full-scale restart.
Workforce Expansion and Community Engagement
The push toward production has coincided with workforce growth. Sunshine currently employs about 150 people, including 110 workers specifically trained for underground operations. This staffing level reflects the company’s preparation for the physical demands of reopening the mine.
Beyond industrial development, the company continues to engage with local residents in Kootenai County and the Silver Valley region. In August, Sunshine hosted its sixth annual Family Day event, drawing more than 220 attendees. The gathering featured catered meals from Garren Taylor of GarrenTeed BBQ and provided an opportunity for employees’ families and community members to tour the facility.
“Family Day went great,” Furlin said, highlighting the positive reception from locals who have watched the mine’s gradual transformation over the past several years. The event marks a significant increase in attendance compared to early gatherings, which drew only 20 to 30 people. Sunshine also hosted Big Creek Day, further strengthening ties with residents living near the mining district.
Impact on North Idaho Economy
The potential return of the Sunshine Mine to production could have lasting economic implications for North Idaho. The Silver Valley has long been a cornerstone of regional identity and employment in Shoshone County, though its proximity to Kootenai County makes it relevant to broader Panhandle economic trends. A successful restart would inject millions of dollars into local supply chains, support skilled labor jobs, and potentially increase tax revenues for state and local governments.
As the company moves closer to its late 2028 target date, stakeholders in Idaho’s mining sector are watching closely. The completion of feasibility studies in 2027 will likely determine whether the projected 23-year mine life becomes reality or requires further adjustment. For now, Sunshine Silver Mining & Refining Co. remains focused on completing infrastructure projects and securing the regulatory and financial approvals needed to bring this historic operation back online.
