The processing facility of the Pumpkin Hollow underground mine has commenced production using development ore from mine construction, and the underground mine itself is expected to commence production before end of 2019. The mine benefits from a number of important, low risk advantages, including a highly-skilled team of mine operators, a supportive local community, established infrastructure, and a desert climate and local topography optimal for efficient and eco-friendly mining techniques such as dry-stack tailings.
