Brunswick in Partnership With Midland Begins a First Exploration Program for Lithium on the Mythril Project North of Patriot Battery Metals Corvette Project

MONTREAL, Aug. 29, 2023 (GLOBE NEWSWIRE) -- Midland Exploration Inc. ("Midland" or the "Corporation") (TSX-V: MD) is pleased to announce the start of a first exploration program for lithium mineralization on its Mythril project, operated by Brunswick Exploration Inc. ("Brunswick"). The Mythril project is under an option agreement with Brunswick since November 2022 (see Midland press release of November 10, 2022). The Mythril project is located in the Eeyou Istchee James Bay region immediately north of Patriot Battery Metals Inc.'s ("Patriot") Corvette project.

Highlights

• New structural interpretation, derived from magnetic data, reveals north-east trending structures, oriented like Patriot's CV13 pegmatites;
• Lithium lake bottom anomalies were identified on the Mythril project following statistical treatment;
• Well located immediately north of Patriot's CV5 spodumene pegmatite with inferred 109.2 Mt at 1.42% Li₂O (0.40% Li₂O cut-off).

The Eeyou Istchee James Bay region is currently the focus of an exploration rush for lithium pegmatites. The Mythril project is located about 1.5 kilometres north of lithium pegmatites discovered on Corvette as reported by Patriot. The Mythril project consists of 380 claims totalling 193.7 square kilometres. A recent maiden resource estimate by Patriot on its CV5 pegmatite (see Patriot's press release dated July 30, 2023) yielded inferred resources of 109.2 Mt at a grade of 1.42% L_i2O with a cut-off grade of 0.40%, leading to establish CV5 as the largest lithium pegmatite resource in the Americas.

New targets and Mythril exploration program for lithium

Initially, the program will mainly focus on the southern part of the project, near Corvettes' lithium discoveries. Several important structural trends were identified by Brunswick and interpreted from high-resolution magnetic data on the Mythril project. These targeted north-east trending structures share the same orientation as Patriot's CV13 spodumene pegmatites. These structures will be targeted by a helicopter-supported prospecting and mapping exploration program, as well as a LiDAR survey.

Furthermore, two new lake bottom lithium anomalies were identified south on the project, following a regional statistical treatment of more than 23,000 analyses and completed by Midland (see Midland's press release of March 6, 2023). The Mythril project has not yet specifically been explored for lithium.

Cautionary statement:

Mineralization occurring on the Corvette project held by Patriot is not necessarily indicative of mineralization that may be identified on properties held by Midland discussed in this press release.
