Sunshine Silver Mining & Refining (SSMR) advanced underground development and infrastructure upgrades supporting the Sunshine Mine's planned production restart in late 2028. The feasibility study remains targeted for the second quarter of 2027, ahead of a future construction decision.
Development totaled approximately 1,200 meters in the first half of 2026; approximately 700 meters of the expected 1,300 second-half meters were complete by September 30. Infill drilling reached approximately 47,600 meters of a 50,000-meter program. A new Jewell Shaft production hoist was commissioned in May, and Silver Summit Shaft upgrades have begun, with work extending into early 2028.
Legacy mill demolition is expected to finish by year-end. The development plan assumes initial processing of up to approximately 1,000 tons per day, with facilities designed to accommodate potential increases to up to approximately 2,000 tons per day.
Sunshine Silver Mining & Refining (SSMR) expanded its consolidated mineral rights in Idaho's Silver Valley by approximately 14,100 acres, a 60% increase, to about 38,000 acres, and launched a multi-year, 45,000-meter district-scale surface exploration drilling program.
The program will initially focus on three drill-ready targets: East Sunshine near the Sunshine Mine, and the Rock Creek and Pine Creek areas. Sunshine expects surface drilling to start in the fourth quarter of 2026. The company’s 2025 reconnaissance program (322 fieldwork days, 128 rock and 2,935 soil samples) defined multiple targets. Separately, a 50,000-meter underground in-fill drilling program at the Sunshine Mine is on track to finish in October 2026, with additional downshaft drill results expected in the fourth quarter.
Sunshine Silver Mining & Refining (SSMR) will be added to the VanEck Junior Gold Miners ETF (GDXJ) effective at market close on September 18, 2026.
The inclusion follows Sunshine’s June 4, 2026 initial public offering on the New York Stock Exchange, coming only three months after its debut. The company’s CEO describes the addition as an important milestone that may broaden its reach among precious metals investors. Sunshine continues to focus on advancing the Sunshine Mine toward a planned return to production in late 2028, while the GDXJ ETF offers exposure to small- and mid-cap global gold and silver mining companies.
