Endomines ends the Care and Maintenance phase at the Friday Mine in Idaho, USA by upgrading the Orogrande Processing facility and continuing development work at the mine.
On August 16, 2021, Endomines announces that ore mining begins at Endomines’ Friday Mine in Idaho, USA and gold production starts in the end of August. Full production estimated by Q4 2021/Q1 2022. |

In early 2018 Endomines AB completed the acquisition of TVL Gold Idaho, now Endomines Idaho LLC, a US mining company that owns the rights to five gold projects in Idaho, USA.
Summary:
The Friday Project is situated near the intersection of the Orogrande and Petzsite shear zones, both of which are relatively broad zones of weak shearing. Within the greaterzone of weak shear, narrower zones of intense shearing are known to contain economically interesting gold grades. All known mineralize zones in the project area are situated between the Friday fault and a conceptual line just a few hundred feet to the east of the Monday fault. Gold mineralization along the Friday fault occurs almost exclusively in the hanging wall in broad seriticized zones within which discontinuous potassic alteration is present, as is weak to strong silicification. Gold mineralization in the vicinity of the Monday fault occurs in local zones of intense ductile shearing and is largely concentrated at the margins of associated dacite-rhyolite dikes.
Summary:
Decision taken to change mining method from shrinkage stoping to cut and fill.
The production capacity of the mine has been enhanced with the purchase of a new mining fleet, and underground services upgrades to allow deeper ore developments.

Summary:
Production and ramp-up at the Friday mine in Idaho, USA Endomines placed the Friday Mine Site on care and maintenance in July 2020 and the Orogrande Processing Facility in October 2020. Since putting the project on care and maintenance, Endomines has proceeded with engineering studies to refine the operating plan.
Specifically, management has advanced plans to correct the throughput issues at the processing facility related to the tailings dewatering system. Plans to update the mill and restart the mine and mill are in place. Endomines expects to resume the process of ramping up production and hiring the remaining staff to operate the mill at the design capacity after installing the tailings dewatering system.
