Duluth Metals Provides Metallurgical Update On Twin Metals Minnesota Project

Stocks in this article: DM

Precious metals including gold, platinum and palladium remain in residue throughout the leaching process and are recovered from the residue via flotation.  A weighted precious metals recovery from the leach residue of 90.9%, 82.6%, and 88.1% for Maturi Bulk #1; 88.2%, 52.5%, and 78.8% for Maturi Bulk #2;  and 75.0%, 75.0% and 75.0% for Maturi Ni-Cu was achieved for gold, platinum, and palladium respectively.

Compositions of the flotation products for each concentrate processed are presented in Table 2.

           Table 2 - Precious Metals Flotation Concentrate Product
                     S (t)       S[o]        Au         Pt         Pd
    Concentrate        %          %         g/t        g/t        g/t
    Maturi Bulk #1    85.8       81.4       6.1        11.0       33.0
    Maturi Bulk #2    93.8       91.4       4.1        5.3        19.8
    Maturi Ni-Cu      97.0       94.6       2.5        6.8        21.4

Although not integrated within the pilot plant flowsheet, bench testwork was performed to further upgrade the material to elemental sulphur and a separate Precious Metals cake using sulphur melting. The grade of the Precious Metals cake for the Maturi nickel-copper concentrate would be approximately 225 g/t assuming the cake retained an elemental sulphur grade of 45%.

Further metallurgical testing will be conducted during pre-feasibility in order to optimize the selected process and flowsheet design.
