The compact and high-grade nature of the known mineralisation at Dianne presents the proven potential for one of the world’s lowest cost copper operations.
The project is made up of a very high-grade copper in a massive sulphide lens coincident with a broad, shallow area of continuous copper oxide mineralisation (Green Hill supergene zone).
It has been interpreted as a strataform volcanic massive sulphide (VMS) deposit. Revolver undertook a detailed geological review comprising field mapping, re-logging and petrography, which has resulted in the view that the Dianne deposit is a Besshi-style VMS lens that has been deformed during regional scale folding and locally overprinted by an orogenic quartz vein gold event associated with the Palmer River gold field.
Initial Mineral Resource Estimate (MRE) for the Dianne Project contains an Indicated and Inferred Mineral Resource totalling 1.62Mt at 1.1% Cu.
The MRE for the Dianne Mine includes the Dianne Primary and Supergene MS which has a total Indicated and Inferred Mineral Resource of 135kt at 6.1% Cu for 8,200t of contained copper metal, at 0.25% Cu cut-off-grade.
Studies are underway to determine optimum scenarios for near-term production potential with further site activities identified with potential to increase resource tonnage.
