| ABSTRACT: | De Grey Mining Limited (ASX: DE GREY MINING LTD, “De Grey”, “Company”) is pleased to announce a significant 29% increase in overall Mineral Resources at the Mallina Project for drilling up to 31 December 2019 compared to the July 2019 Total Gold Mineral Resource (JORC 2012). The resource upgrade includes updated resource models for Withnell open pit, Withnell Underground, Toweranna open pit depth extensions and Toweranna underground, together with significant and shallow extensions to the Mallina resource. The new resources are based on all drilling completed at each deposit up to the end of 31 December 2019. The open pit resources are quoted using a 0.5g/t lower cut-off grade and the Withnell and Toweranna underground resources using a lower cut-off grade of 2g/t. The resources at Mt Berghaus, Wingina, Amanda, Camel, Roe, Dromedary and Calvert remain unchanged and will be updated after further drilling is completed at each deposit. The underground resource grade now averages 3.9g/t Au with individual lodes ranging from 2.7g/t up to 7.3g/t. The mineralisation remains open along strike and at depth along the entire 6km of known strike potential from Withnell through Hester, Camel, Roe and Dromedary deposits. | |
