RE: Walker Lane gold trend: Future of gold mining in Nevada12 Sep 2020 23:37
A few recent successes at Walker Lane include Northern Empire’s US$90 million acquisition by Coeur Mining (NYSE:CDE) in 2018 on the basis of the Sterling gold project, which hosts four distinct deposits including a fully-permitted, open-pit mine set to become one of the highest-grade heap leach mines in the Western United States.
Corvus Gold (TSX:KOR,OTCQX:CORVF) is focused on its near-term North Bullfrog and Mother Lode gold-silver mining projects near Beatty, Nevada. Results from exploration drilling at Mother Lode continue to show high potential for expanding the deposit and raising the possibility of identifying a much larger mineralization system. Corvus’ success has attracted C$2 million in additional funding for resource expansion programs at both Mother Lode and North Bullfrog.
Newrange Gold’s (TSXV:NRG,OTC Pink:NRGOF) Pamlico gold project represents another high-grade, district-scale opportunity on the Walker Lane trend. The project includes the historic Pamlico Mines on Pamlico Ridge, together with the Central, Sunset, Good Hope, Gold Bar and various unnamed mines and prospects. The 1,670-hectare property has been in private hands since 1896 with less than half of 1 percent of the property ever touched by a modern exploration drill. Newrange acquired Pamlico in 2016 and since then has launched an aggressive exploration campaign which has resulted in numerous drill intercepts of near surface oxide gold mineralization to 340 grams gold per metric tonne.
Newrange is advancing the project toward a resource estimate. In February 2019, the company completed preliminary metallurgical testing which achieved gold extractions as high as 97.1 percent and calculated head grades as high as 79.4 grams gold per metric tonne. These grades were substantially higher than what was originally indicated by drill sample assays, suggesting the potential for a much larger and potentially heap leachable gold system at Pamlico.
