After three years of exploration, Enduro is confident there are at least four large mineralized systems – McLymont, Burgundy, Cuba and Chaci – at Newmont Lake.
A high-grade copper-gold epithermal skarn has been identified at McLymont. Burgundy hosts a copper-gold alkalic porphyry. Cuba is a high-grade silver-zinc-copper epithermal skarn. Chachi, which looks to have the largest mineralized zone, has never been drilled. It has the potential to host a multi-element zone that is either an alkalic porphyry or an iron ore-copper-gold deposit.
The Burgundy porphyry was discovered in October 2021 when hole BR21-001 intersected 331 metres of 0.71% copper-equivalent starting at surface, including 18.3 metres at 3% copper-equivalent. The system has been traced on surface along 2,700 metres and up to 600 metres wide.
Enduro also sampled the Cuba mineralization in 2021 along an 1,800-metre anomaly. A quartz-barite vein on the surface returned 1,277 g/t silver, 4.51% copper, 1.11% zinc, and 0.21% lead. Sixty metres along strike, another surface sample assayed 854 g/t silver, 5.34% copper, 4.34% zinc, and 1.53% lead.
When the McLymont fault was drilled in 2020, all 17 holes returned gold mineralization. One hole highlighted by the company returned 28.3 metres grading 10.48 g/t gold, 2.31 g/t silver and 0.36% copper, including 8.9 metres at 32.52 g/t gold, 6.54 g/t silver and 1.07% copper beginning 160 metres down hole.
Enduro was granted the option on the Newmont Lake project in 2018. Since that time, it has completed C$8 million in exploration work, made staged payments to Romios totalling C$2 million, and granted Romios a total of 12 million Enduro shares.
