Pilbara Minerals Limited reported further significant assay results from the current exploration and resource extension drilling program underway at its 100%-owned Pilgangoora Project in Western Australia. The drill program is targeting the under-explored region on the tenement boundary adjacent to the former Altura Lithium Operation (now known as the Ngungaju Plant and associated facilities), with the intention of optimising and growing the future pit inventory. Initial results from the program have identified zones of high-grade pegmatite mineralisation adjacent to the tenement boundary and future South Pit expansion area which is outside of the previously identified Mineral Resource. 10,158 drill metres completed with an extension to the initial program currently underway. Further promising assay results received for the first 32 Reverse Circulation holes of the 62-hole program, with select new intercepts indicating: 20m@ 1.83% Li2O and 36 ppm Ta2O5 from 28m (PLS1328), 12m @ 1.84% Li2O and 67 ppm Ta2O5 from 5m (PLS1330), 21m @ 1.28% Li2O and 62 ppm Ta2O5 from 25m (PLS1337), 32m @ 1.44% Li2O and 79 ppm Ta2O5 from 159m (PLS1337) and 44m@ 1.49% Li2O and 76 ppm Ta2O5 from 146m (PLS1341). New near surface pegmatite domain identified, suggesting a lower strip ratio within the potential mine pit inventory of the combined South Pit. Drilling continues, with an update to the Pilgangoora Project Mineral Resource on track for delivery in the September Quarter 2021.
