Galaxy Resources Limited announced a Mineral Resource and Ore Reserve update following drilling activities undertaken during the second half of 2018 at the Mt Cattlin Project in Ravensthorpe, Western Australia. There has been a 42% increase in classified Resources compared with the equivalent position as at June 2018. Ore Reserves continued to be modeled using a USD 650 per tonne revenue factor and have increased 40% overall to 10.7 Mt (Proven and Probable) @ 1.15% Li2O and 137 ppm (parts per million) Ta2O5. Ore Reserves were last updated in December 2017. These increases take into account the additional drilling completed in the second half of the year and also reflect an increase in measured resources, as well as an increase in inferred resources completed during that period. A 17% dilution at zero grade and 93% mining recovery have been applied to the Ore Reserve. During the second half of 2018, Galaxy received all necessary approvals from the West Australian Department of Mines, Industry Regulation and Safety to transition mining away from the Dowling and 2SW pits, which had been the focus of mining since the recommencement of production at Mt Cattlin, to begin mining east of and on Floater Road. State approval was also received to increase the process plant throughput to 2.0 million tonnes per annum. The yield optimization program, which included the installation of an ultrafines DMS circuit, ore optical sorting circuits, and a WHIMS circuit has now reached practical completion. The Mineral Resource estimate was completed by independent consultant Mining Plus. Galaxy was responsible for the logging, sampling, analytical and QA/QC protocols. Mining Plus was responsible for the interpretation and modeling of the geology and lithia, as well as related mineralization, geostatistical analysis, block modeling, resource and ore reserve classification. The spodumene mineralization at Mt Cattlin is entirely hosted within numerous flat-lying pegmatite intrusions, with these pegmatites cross-cut and offset by many late stage faults. Those faults have been used to differentiate the pegmatites into six different areas for interpretation and modeling, with the geological modeling completed in Surpac 3D modeling software. In order to minimize the mafic host rock dilution within the resource and to improve ore processing performance, also as a result of RC drilling being the predominant drilling used to define the deposit, Mining Plus has modeled the pegmatite boundaries using a combination of logged lithology, Li2O%, Fe2O3% and MgO% grade fields. Mining Plus has also modeled internal rafts of mafic host rock intersected in drill holes. The same process of using a combination of assays and logged lithology has been used to define the boundaries of the internal waste domains. The Li2O estimation has been undertaken using ordinary kriging into both the mineralized and unmineralised pegmatite domains, with some sub-divided further into oxidized and transitional/fresh domains. Galaxy collected 1,076 bulk density measurements throughout the mineralized and un-mineralized pegmatite within the waste lithologies at Mt Cattlin. Average values were calculated from the complete dataset and coded to the block model based on the oxidation state and nature of the mineralization. The drill hole database for the Mt Cattlin deposit comprised of 3,956 drill holes for a total of 177,268.6 meters of combined reverse circulation, diamond drilling, percussion and grade control drill holes.
