By 1910 all mining operations at Tantiusques had ceased. Although forest has since reclaimed the area, mine cuts, ditches, tailings piles and several shafts are still visible. The mineshaft that tunnels into the face of the low ridge is the most recent of the excavations, dating to 1902. Most of the mining at Tantiusques was of the open trench variety. A cut along a ridge top on the property is the partially filled-in remainder of what was once a long trench, to deep, and roughly 6 feet (2 m) wide.
