Centaurus Metals (ASX:CTM) said that the value engineering process for the Jaguar nickel project in Brazil boosted the feasibility study economics while demonstrating a long-life production profile at first quartile operating costs with low capital intensity, according to a Monday Australian bourse filing.

The process showed an initial 15-year mine life, delivering nickel sulfide feed to a 3.5 million tonnes per annum conventional nickel flotation plant to produce around 22,600 tonnes per annum of recovered nickel metal-in-concentrate over the first seven years of full production.

The process further identified a life-of-mine average production profile of 18,700 tonnes of recovered nickel metal per annum at a life-of-mine C1 operating cost of $3.34 per pound and all-in sustaining costs of $4.43 per pound, on a payable nickel basis.

The key approvals for the project are in place.

The firm's shares rose 1% in recent trading on Monday.
