Gidgee North

Murchinson Projects

Gidgee North

The Gidgee North project is located approximately 640km northeast of Perth in the Murchison region of Western Australia and comprises tenements E53/1920, E51/2044, E51/2032, E53/2227, E51/2090 and Geoff Well farm-in project E53-1832-I, covering approximately 430 km2. The project lies within the Gum Creek Greenstone Belt of the Youami Terrane, which forms a lensed, broadly sinusoidal belt measuring some 100 Km in length and 24 Km in width.  The Gum Creek Greenstone Belt has historically produced over 1 Moz of gold and hosts over 1.35 Moz of gold Mineral Resource[1].

Gold Prospectivity

Large areas of the Project remain essentially unexplored despite favourable geological and structural settings.  With the aid of specialist consultants, Westar has generated multiple gold targets from extensive geochemical and geophysical datasets.  These targets will be advanced through boots-on ground prospectivity mapping and sampling with the highest ranked targets planned for aircore and reverse circulation drill-testing in CY23.

Base metal prospectivity

Detailed analysis of SkyTEM AEM data flown over the project by Panoramic resources in 2015 identified multiple conductors over the Gidgee North Project that are potentially analogous to the nearby Altair Cu-Zn prospect, held by Horizon Gold (ASX: HRN).   The Geoff Well farm also contains historical base-metal drilling with assays including 20m@ 0.17% Zn in GVER001 and 8m @ 1.12% Cu in GVER010.

Westar refined the SkyTEM AEM targets in late 2021 and early 2022 with detailed mapping, soil sampling and ground geophysics.   In 2022, Westar completed the proof-of-concept Cu-Zn VMS / Sedex drilling campaign, noting the similarities of the Vela and Geo prospects with the nearby HRN “Altair” prospect, which includes 55.0m @ 3.32% Zn, 0.52% Cu, 9.4g/t Ag from 184.0m[1] 

The Project is considered to have fertile Cu and Zn horizons in a palaeo-seafloor exhalative system.
