A desktop review undertaken by Western Yilgarn NL (ASX: WYX) has identified several exciting targets including potential for Gonneville style finds at the Julimar West Project in Western Australia
The company continues to progress activites at its 100% owned, recently renamed Julimar West Project, located adjacent to Chalice Mining’s Julimar Project which contains the three Mt NiEq Gonneville Resource.
Western Yilgarn says it continues to be encouraged by the ongoing successful exploration efforts reported by its neighbour Chalice Mining Ltd following confirmation of the major northern extension of the Gonneville Intrusion.
Chairman, Peter Lewis, said the Gonneville Intrusion is located less than 2.5km east of the Julimar West Project tenement border, with the Chalice interpreted fault running into the Julimar West Project area.
“Julimar West targets probably the most exciting new battery metals discovery zone in the world, namely the three Mt NiEq Chalice Mining Gonneville Discovery.
“Despite the long delay in DMIRS processing our application, we are expecting the grant of our EL 70/5111 application to be completed soon after the removal of an FNA from our application area, by the end of June 2023.
“The grant of our application will enable Western Yilgarn to immediately commence a staged exploration program targeting several exciting opportunities in a world class mineralised zone recently established by Chalice Mining.”
Western Yilgarn has undertaken a desktop review of publicly available data including ASX releases from Chalice Mining plus WAMEX data from the Department of Mines, Industry Regulation and Safety (DMIRS) site.
Key prospective targets defined from the desktop review include:
- Down dip extensions of the Chalice Gonneville Intrusion, host to the main mineralisation, which dips to the West at ~40 to 45 degrees. The Julimar West application area is located ~2.5km directly West. Seismic surveys by Chalice demonstrate that the intrusion could potentially continue at depth into Julimar West.
- Repetitions of Gonneville mineralisation (within layered intrusions) have been interpreted in Western Yilgarn’s ground, defined by geophysical data as weakly defined magnetic features. There has been very little exploration work completed on the Julimar West Project to date.
- Pegmatite units which have been sampled by the GSWA in regional grab sampling work. These are located in the South – West Terrane greenstone unit which strikes over 9km in the southern part of the Julimar West Project. GSWA grab samples have returned significant Tin, Niobium and Tantalum results along with anomalous Lithium. Additional field reconnaissance by Western Yilgarn has located outcropping pegmatites within the region.
- Potential in the northern section of ELA 70/5111 for gold mineralisation associated with greenstone units.
