Amur Minerals Corporation (LON:AMC) has revealed that individual copper and nickel sulphide concentrates can be generated from ore at its Kun-Manie project in Russia.
From the projected six million processed ore tonnes per annum 39,300 tonnes of copper concentrate is likely to be created, with an average copper grade of 23.4%.
The test-work post-dates the February 2019 prefeasibility study, wherein the base case all-metal concentrate derived revenues from payable nickel only.
The ability to generate a separate copper concentrate should materially and substantially impact the economic potential of the project, with the recovery of additional revenues related to the payable portion of 9,182 tonnes of copper per annum.
By-product metals within a copper concentrate often source additional revenues, gold and silver in the case of Kun-Manie.
