A total of 6,000 meters is expected to be drilled across both assets with approximately 2,000 meters planned at Anatacau and 4,000 meters to be drilled at Mirage. Mr. Killian Charles, President and CEO of BRW, commented: “With an inferred Mineral Resource Estimate (“MRE”) of 52.2Mt grading 1.08% Li2O, Mirage is already one of the most important lithium assets in Canada. We see significant potential to rapidly expand both the MRE and the associated Exploration Target. Many of the pegmatites drilled to date remain open in all directions and, in addition, several lithium-bearing pegmatites have yet to be drill tested. In parallel, we believe that Anatacau could be as significant as Mirage. The drilling will continue to outline the potential we see at this asset. No other lithium junior company in Canada has such a unique combination of advanced, high potential assets. We believe the planned summer campaign will cement our position as one of the most exciting lithium exploration companies in Canada.” Figure 1: Project Location <img alt="Project Location" height="486" src="https://ml.globenewswire.com/Resource/Download/d07c03e9-bd03-4a97-a399-4d7c426adaf5/figure1.png" width="600" data-dpi="300" data-caption="Project Location" data-filename="Figure1.png" /> Overview of the Summer Drill Program Drilling will initially begin at Anatacau for approximately one month before moving to Mirage for the remainder of the campaign. A total of 6,000 meters is expected to be drilled with 2,000 meters allocated at Anatacau and 4,000 meters allocated at Mirage. However, final meterage at either project may be expanded as necessary as we continue to expand both assets. Overview of Anatacau Drilling The drilling at Anatacau aims to extend the known spodumene pegmatite dykes as well as to discover new ones. The spodumene pegmatite dyke field defined to date at the Anais zone extends over 600 meters long and 450 meters wide and remains open in all directions. The largest spodumene-bearing pegmatite, the Anais Main dyke, measures approximately 40 meters in width and recently extended the strike length to over 350 meters (see June 10th 2026 news release). Several mineralized pegmatites, exceeding 10 meters in width, surround Anais Main dyke and are interpreted to be in a stacked pegmatite system. The most significant intercepts thus far include 1.31% Li2O over 120.7 meters in hole AN-25-05 and 1.31% Li2O over 90.5 meters in hole AN-26-07. Overview of Drilling at Mirage Drilling will initially target the lateral extension of the MR-1 and MR-4 dykes, which are the richest dykes to date at Mirage. The MR-1 dyke is in the northern part of the deposit and is defined over 400 meters in strike length and remain open in all directions. This dyke returned high grade results including 2.57% Li2O over 25.8m in hole MR-23-02 (see January 24th, 2024 news release). Drilling will then move to MR-4 dyke, the most evolved pegmatite on the project so far, located in the southern part of the deposit. It is defined over 600 meters in strike lengths and remains open in all directions. MR-4 also returned high grade results including 2.75% Li2O over 16.2m in hole MR-23-14 (see January 24th, 2024 news release). The campaign will continue with drilling untested spodumene pegmatite outcrops, particularly north of the Escale lake. Additional drilling is also planned to test new high-potential targets along the entire 8-km-long lithium-bearing corridor identified to date at Mirage with more than 350 spodumene pegmatite boulders and locations with spodumene in tills so far. Drilling will be conducted using a helicopter-borne drill rig over a period of approximately two months.
