Recent airborne geophysical survey identified numerous Hemi style gold targets
Historical drilling identified Ni/Cu/PGE mineralisation
Airborne EM survey planned in 2023 to identify conductors for drilling
RC drilling programme planned for 2023 to test EM and Hemi style gold targets
The Mallina Gold Project (“Mallina”) comprises four tenements (three granted, one application) covering approximately 1,728km2 of the Mallina Basin in the Northern Pilbara of Western Australia. De Grey Mining Limited’s Hemi deposit is located approximately 120km to the southwest of Mallina with historical geophysical data suggesting that the majority of the tenement package is underlain by the Mallina Formation.
Mallina comprises one of the largest tenement holdings assembled within the Mallina Basin, of which three of four tenements were applied for prior to the discovery of Hemi. Hemi is identified as an intrusion hosted gold deposit which is a new style of gold mineralisation in the Pilbara region. These intrusions are hosted in the Mallina Formation within the Mallina Basin, part of the De Grey Superbasin.
There has been limited drilling and historical gold exploration conducted over the Mallina Gold Project. The limited geological understanding of Mallina has been derived through geophysical data with some previous interpretation utilised to obtain an overall understanding of the geology of the area.
