    General Mining Corporation Limited (ASX:GMM, “General Mining”, “GMM” or the “Company”), together with its partner on the Mt Cattlin Project (“Project”) Galaxy Resources Limited (ASX:GXY) is hereby pleased to announce the following update on the recommissioning process at Mt Cattlin.

    General Mining Corporation Limited (ASX:GMM, “General Mining”, “GMM” or the “Company”), together with its partner on the Mt Cattlin Project (“Project”) Galaxy Resources Limited (ASX:GXY) is hereby pleased to announce the following update on the recommissioning process at Mt Cattlin.
    Mt Cattlin last operated from 2011 to mid‐2012 under the stewardship of the previous Board and Management of Galaxy, with production statistics for the 6 months to 30 June 2012 including (see Galaxy 2012 Annual Report, p.11):

    • Ore mined (tonnes) – 454,912
    • Grade (Li20%) – 1.22%
    • Waste mined (BCM) – 925,505
    • Ore treated (tonnes) – 453,004
    • Grade (Li20%) – 1.23%
    • Spodumene produced (dry tonnes) – 54,047

    On 12 October 2015, General Mining announced an independent review of its plan for the recommencement of production at Mt Cattlin based on the following parameters:

    • Annual throughput (ore treated, tonnes) – 800,000
    • Average annual LOM spodumene production (dry tonnes) – 111,000
    • Peak spodumene yield – 75%

    Following maiden commissioning of the fines circuit at the Project in March 2016, construction has continued and will now result in a significantly expanded processing capacity at Mt Cattlin:

    • Annual throughput (ore treated, tonnes) – 1,600,000
    • Average annual LOM spodumene production (dry tonnes) – 160,000‐240,000
    • Peak spodumene recovery – 75%

    This change has been driven by the substantial efficiency gains on offer to the Project owners in installing a larger circuit, as well as the opportunity for Mt Cattlin to meet significant market demand for spodumene concentrate at a time of constrained supply into the China based lithium refining markets. First shipment from the enlarged circuit remains scheduled for September 2016, no delays to deliveries have been incurred due to the upgrading of capacity at Mt Cattlin.

    Progress Update

    Mining and maiden commissioning of the fines circuit at the Project occurred in March 2016. After reaching the initial desired commissioning and production milestones, the Project went back into a construction phase to complete the refurbishment and upgrade of the coarse circuit, and to implement final changes to the significantly improved fines circuit.
    The new circuit will:

    • Reduce mica content below 5% of total mass in the finished concentrate (previously approx. 20%)
    • Increase throughput design to an annualised run rate of 1.6Mtpa (previously assumed by GMM to be 800,000tpa)
    • Increase yield from a historic 50% to approximately 75% by recovering both fine spodumene and coarse tantalum, as well as significantly reducing mica content
    • Reduce operational costs per tonne through a number of efficiency gains

    Over the last three months, mining of the ore grade TSF material has been largely completed (50kt ore remains in situ) and is currently stockpiled ready for use as feedstock in the fines circuit. The ROM pad currently holds 100,000t of blasted ore ready for crushing and feeding into the coarse circuit.
    Key milestones during July to September 2016 include:

    • Crushing of ROM ore stocks to commence during July
    • Upgraded fines circuit to achieve targeted 1.6Mtpa throughput rate in early August
    • Commissioning of the coarse circuit due to commence mid‐August
    • First shipment of spodumene concentrate confirmed for late September 2016

    Post start up at a budgeted lithium yield of 50%, further optimisation will increase this to 75% by mid‐2017. Previously scheduled for the beginning of 2017, peak metallurgical recovery across the 1.6Mtpa throughput will now occur in two phases with the final optimisation stage (flotation) subject to performance of the plant post commissioning.
