Centaurus Metals (ASX:CTM) said process flowsheet refinement at its Jaguar nickel sulfide project in Brazil delivered over 30 kilograms of high-grade concentrate grading 34% nickel in a pilot plant trial, according to a Tuesday Australian bourse filing.
The flowsheet refinement is part of the Jaguar value engineering process, which is meant to produce a high-grade nickel concentrate with low impurities.
It is evaluating the capital and operating cost impacts of the revised process flowsheet, as well as whether any amendments are required to the environmental approval process.
Its shares rose 6% in trading on Tuesday.
