Western Yilgarn (ASX:WYX) has expanded the JORC-compliant footprint of its West Julimar Bauxite Project in Western Australia after executing new land access agreements over Zones 100 and 200, securing access to extensive lateritic bauxite immediately adjoining and between its existing mineral resource areas.
The agreements provide continuous access across the majority of the laterite–gravel system hosting the company's combined 104.8Mt inferred JORC-compliant Bauxite mineral resource, comprising 42.6Mt at 31.8% Al₂O₃ at Zone 100 and 62.2Mt at 36.4% Al₂O₃ at Zone 200.
The newly accessible ground includes large, previously unexplored areas of prospective laterite that extend beyond current resource boundaries and link the two deposits within a single geological system, opening the mineralised footprint to systematic drilling.
Initial work programs will include mapping, geochemical sampling, rock-chip collection and environmental studies ahead of drill targeting, with the company planning shallow, low-cost aircore and auger drilling to test strike and lateral extensions, infill areas between the deposits and undrilled laterite plateaux.
Western Yilgarn said the agreements represent a key operational milestone and provide a clear pathway to materially expand the existing bauxite resource as it continues to advance its alumina portfolio in the highly prospective Darling Range Mineral Field.
At the time of reporting, Western Yilgarn's share price was $0.033.
