# PLS reports 31% rise in contained lithium oxide in Pilgangoora Ore Reserve > PLS said on 15 October that Pilgangoora’s Ore Reserve had reached 249.2 million tonnes. At a grade of 1.24% lithium oxide, this represents about 3.1 million tonnes of contained lithium oxide; contained lithium oxide increased 31% against the previous reserve estimate. - Canonical URL: https://newsverum.com/en/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium - Publisher: Newsverum - Section: Business - Country: Australia - Published: 2026-10-21T00:44:03+00:00 - Updated: 2026-10-21T00:44:03+00:00 - Event / data period: 2026-10-15 - Other editions: [Türkçe](https://newsverum.com/tr/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium.md), [العربية](https://newsverum.com/ar/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium.md), [Français](https://newsverum.com/fr/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium.md), [Español](https://newsverum.com/es/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium.md), [Deutsch](https://newsverum.com/de/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium.md), [Português](https://newsverum.com/pt/news/pls-pilgangoora-ore-reserve-rises-31-percent-contained-lithium.md) The reserve update followed the P2000 feasibility study and a separate pre-feasibility study on potential underground mining. The open-pit reserve supports about 20 years of production under the P2000 plan, extending to more than 25 years if underground mining is included. The reserve includes a maiden underground component of 46.5 million tonnes at 1.50% lithium oxide. PLS is progressing a feasibility study of the underground option; any underground development would require a separate investment decision. ## Data ### PLS reports 31% rise in contained lithium oxide in Pilgangoora Ore Reserve Methodology: Event and scope as stated in the official release. | date | label | description | status | |---|---|---|---| | 2026-10-15 | Pilgangoora Ore Reserve updated | PLS said on 15 October that Pilgangoora’s Ore Reserve had reached 249.2 million tonnes.
