Libra Commences Maiden Exploration Program Across James Bay Lithium District in Quebec

Toronto, Ontario--(Newsfile Corp. - October 21, 2025) - Libra Energy Materials Inc. (CSE: LIBR) (FSE: W0R0) ("Libra" or the "Company") is pleased to announce it has commissioned Laurentia Exploration to begin a reconnaissance prospecting program on its newly staked and 100%-owned Wegucci lithium project, strategically located in the James Bay region, Quebec, along strike of Rio Tinto's Whabouchi lithium deposit. Laurentia Exploration will also be conducting initial fieldwork on Libra's 100%-owned Nemiscau lithium project, also located in the James Bay region of Quebec, approximately 18 kilometres ("km") south of the Cygnus Metals' Pontax lithium deposit. This program also contemplates field visits to unowned projects that are under consideration for potential future acquisitions by Libra.

"This program marks our first time getting boots-on-the-ground in Quebec. Our 100%-owned Wegucci and Nemiscau projects are both located in the highly prospective region of James Bay, where some of the world's most significant lithium discoveries have been made. Nemiscau is a project we have held since 2023, while Wegucci is a newly staked property along trend of Rio Tinto's Whabouchi deposit. In addition to their prospectivity, both projects benefit from proximity to infrastructure, including being within 22 km from the nearest road. We are very excited to test the prospectivity of these projects in due course," said Koby Kushner, Chief Executive Officer of Libra Energy Materials.

Wegucci Overview

The Wegucci property is located within the Lac des Montagnes volcanic-sedimentary belt of the Opatica Subprovince of the James Bay region, Quebec. The project spans 2,070 hectrares ("ha") and is strategically located along the same major structure and subprovince boundary that hosts Rio Tinto's Whabouchi lithium deposit, amongst several other lithium-cesium-tantalum pegmatite occurrences (Figure 1).

Most of the Wegucci property is made up of an important mafic volcanic unit and a biotite-garnet paragneiss, which are juxtaposed against a biotite-hornblende sedimentary unit to the north. The contact with the sedimentary unit is understood to represent a major regional structure and an important control on lithium mineralization in the area. There is no known historical work focusing on lithium exploration on the property. Preliminary desktop work by Libra utilizing satellite imagery shows large white outcrops over 30 metre ("m") in width interpreted to be potential pegmatites that will be priority targets for the upcoming fieldwork program (Figure 2).

Nemiscau Overview

The Nemiscau property is located in the Eastmain subprovince near James Bay in northern Quebec, approximately 18 km south of Cygnus Metals' Pontax lithium deposit. The property is 2,454 ha in size and has been historically mapped with a rose pegmatitic granite that is in contact with a biotite-bearing granite to the west and a quartz monzodiorite to the east. Most of the property remains underexplored with only the most southern area having government mapping completed on it that confirmed the presence of pegmatites between 10 - 100 m in width. Visiting the historically mapped pegmatites, in addition to visiting several unexplored outcrops elsewhere on the property will be the focus of the initial field program on the property.
