In 2017 Sundance?s exploration and development operations included completing two portals, approximately 650 feet of tunnel (10.5-feet wide by 10.5-feet high), and 350 feet of drift (10.5-feet wide by 10.5-feet high) by rubber-tired mining equipment. Additionally, 140 feet of raise and scram development was completed utilizing jackleg and slusher-type mining. Exploration work included geologic mapping of a 1,400-foot-long lateral drift. |

During 2018, Sundance completed Phase II permitting allowing for mill development, production mining, and milling. Their continued underground exploration/development program completed approximately 450 feet of rubber-tired drifting on vein, and approximately 480 feet of jackleg/slusher scram up-dip and along strike of the Humboldt vein system. Approximately 4,000 tons of initial mill feed were produced. |
