Highfield Resources Limited announced that it has provided an updated Ore Reserve estimate for the Company's Muga Potash Project This update relates to a revised Ore Reserve Statement prepared by Highfield Resources and audited by SRK Consulting (UK) Limited. The Proved and Probable Ore Reserve has been derived from the Measured and Indicated Mineral Resource of 235 million tonnes as previously reported on 10 October 2018 and comprises 108.7 million tonnes at 10.2% Potassium Oxide ("K2O", potash), with a Proved Ore Reserve of 42.9 million tonnes at 10.2% K2O and a Probable Ore Reserve of 65.8 million tonnes at 10.2% K2O. As a result of additional detailed 3D modelling undertaken after the release of the Muga Project Update statement dated 15 October 2018, the total Ore Reserve of 108.7 million tonnes is modestly different from the 117 million tonnes of Muga mining inventory previously reported.
