Gold Rush: Dave Turin's Lost Mine

This spin-off series followed Dave Turin, formerly of the Hoffman crew, as he looked to start new mining operations at disused gold mines in the Western United States. Dave Turin set up Golden Streets Mining LLC as the mining company for this venture. The series debuted in March 2019 (the mining took place in 2018), centering on a placer mine along Lynx Creek near Prescott Valley, Arizona (season gold total 80oz, $96,000). In 2020 (the mining took place in 2019), the show's second season ran from February to April, with eight episodes centering on a placer mine along Silver Creek in Birdseye, near Marysville, Montana (season gold total 225.1oz, $340,000). In 2021 (the mining took place in 2020), the show's third season ran 16 episodes from March to July, centering on a placer mine along Box Creek in Lake County, Colorado for 12 weeks (gold total 426.8oz, $810,000) before moving back to Lynx Creek in Arizona for the last four weeks (gold total 174oz; whole season gold total 600.95oz, over $1,000,000). In 2022 (the mining took place in 2021), the show's fourth season ran 16 episodes from May to September, centering on a placer mine along Glacier Creek in the Chugach Census Area, near Valdez, Alaska, for 13 out of 20 weeks (season gold total 463oz, over $800,000).
