On 3 February 2022, Endomines updated its production forecast for the Friday mine. Operations at the Friday mine and Orogrande enrichment plant have been temporarily suspended. The company is focusing on underground drilling to gain an even better definition of the forms and limits of the ore. Intensification of operations is expected to continue once the drilling results are obtained, provided that the results are in line with expectations.
No gold production will be realized from Friday during H2 2022. |

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.
Investments were made to upgrade the mine’s production capacity to 50,000 tonnes ore annually. This was done through the purchase of a new mining fleet, including two 4-yard and one 1 1/2-yard underground loaders. Also, a single boom jumbo, a long hole drill and a underground ore haul truck was “leased to purchase”. In addition, various upgrades to the mine infrastructure were also done. By becoming an “owner miner”, the company will have greater flexibility in planning mining. Further upgrades in equipment and infrastructure will be required for any deeper ore development.
Mining started late summer and milling during the fall. The ramp up and commissioning was planned to be complete by the end of Q4 2021. However, mining of the first stopes and initial underground diamond definition drilling revealed that the ore appears to be more irregular than originally had been interpreted. Therefore, a second phase of diamond drilling has been initiated. The underground drilling will continue in 2022 with the aim to ensure sufficient reserves are confirmed for future production schedules.
Due to the need to carry out more underground definition diamond drilling for further mine planning purposes, minin ........
