Company Description
Sunshine Silver Mining & Refining is the owner and developer of the permitted Sunshine mine and permitted silver/copper refinery located one mile north of the Sunshine Mine, as well as the associated facilities including a tailings storage facility and historical antimony refinery grounds.
The Sunshine Mine is a historic, permitted, large-scale past-producing silver mine in the United States, which historically also produced meaningful quantities of antimony, copper and lead.
The Sunshine Mine is one of the highest-grade primary silver resources in the world, with an average diluted silver grade of 1,022 grams per tonne of Indicated Mineral Resources and 776 grams per tonne of Inferred Mineral Resources.
When production is restarted, we expect the Sunshine Mine will also be one of the largest silver mines in the United States.
We plan to restart operations at the Sunshine Complex in 2028.
