Generation Mining Generation Mining hold one of the largest undeveloped palladium resources in Canada M ounces located north of Marathon The Feasibility Study FS the deposit contains copper and palladium will be complete in Q1 and the Federal Environmental Assessment Joint Review Panel re commenced in 2021
Conducting bulk ore sorting at the mining face either in pit or underground allows ore and waste to be directed to the appropriate destination waste dump or process immediately The feasibility of this approach will depend on having suitable space available for the sorter as well as on the mining method employed and potential impact on
The production rooms being mined were about 75 ft wide and 5 000 ft long That is quite a large span not likely possible in many other rock types other than salt rock Overall the mine would extract about 40 45% of the potash leaving behind the rest in the form of large pillars to support the overlying rock mass

Sandvik Mining and Rock Solutions will supply a battery electric haul truck and loader to evaluate performance and suitability for future underground mining fleets Pre feasibility studies are also being progressed to extend open pit mining at Kennecott beyond 2021 with a further push back of the North Wall to allow access to Mineral Resources
Potential underground mining would occur concurrently with open pit operations and result in increased copper output The feasibility study work is expected to be completed in 2021 and will focus on gathering critical geological geotechnical and hydrogeological data
Mining 1 Most sulfide ores are taken from huge open pit mines by drilling and blasting with explosives In this type of mining the material located above the ore called the overburden is first removed to expose the buried ore deposit This produces an open pit that may grow to be a mile or more across Online Service
The project was at the feasibility stage and the feasibility study was scheduled to be completed in early 2021 A prefeasibility study for the oxide expansion project was also underway in 2021 AngloGold Ashanti Ltd 2021 p 94 95 Gold production from Syama open pit mine increased by about 215% to 2 425 kg from 770 kg produced in 2021
