Galaxy Resources (GXY) has provided an update to its Mt Cattlin lithium project Mineral Resource and Ore Reserve estimates. The company reports a mineral resource depletion of 2.1 million tonnes from mining operations through 2019 – yielding a new estimate of 14.6 million tonnes at 1.29 per cent lithium oxide. A yield optimisation project was completed in 2019 as part of Galaxy's strategy to increase product quality to meet tightening customer specifications, as battery manufacturers must report the carbon footprint for source materials, and require resources of the highest purity.
