Peregrine Gold (ASX:PGD) completed has identified Hemi style intrusive gold targets at its Mallina Project area in Western Australia following a detailed airborne geophysical survey.
Line spacing was at 50m for a total of 36,589-line kilometres.
The company reports the interpretation of this geophysical database was undertaken by Fathom Geophysics. Fathom has extensive experience in intrusive hosted gold systems in a variety of geological terrains and use a number of proprietary technologies including intrusion detection as part of their interpretation.
Fathom’s interpretation and report has identified three geological domains including an extensive block of Mallina Basin sediments and Millindinna Suite intrusions which underlie a Phanerozoic cover sequence.
The basement has been interpreted to have similarities in structural and lithological character as the prolifically mineralised De Grey Mining Mallina Basin gold camp at Hemi
The basement has been interpreted to have similarities in structural and lithological character as the prolifically mineralised >10Moz De Grey Mining Mallina Basin gold camp at Hemi, located about 100km to the south-west.
The geophysical interpretation has identified up to 84 late intrusive features which may represent Hemi style targets.
The intrusions appear as clusters and are located near favourable structures making them priority targets.
In addition to the Hemi style targets a review of WAMEX open file reports within the project area has identified the potential for nickel, copper, and PGE mineralisation.
Follow-up work will now include lodging a Programme of Work (POW) application with the Department of Mines, Industry Regulation and Safety (DMIRS), undertaking heritage clearance surveys, RC drilling of priority targets, and additional geophysical techniques including gravity surveys.
The Mallina Gold Project comprises four tenements (three granted, one application) covering approximately 1,728km-square of the Mallina Basin in the Northern Pilbara of Western Australia.
De Grey Mining’s Hemi deposit is located some 120km to the southwest of the NFR tenements 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.
Peregrine reports 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.
