RIO Tinto IN Partnership with Midland Begins a First Exploration Program FOR Lithium ON the Mythril Regional and Galinée Projects
RIO TINTO IN PARTNERSHIP WITH MIDLAND BEGINS A FIRST EXPLORATION
PROGRAM FOR LITHIUM ON THE MYTHRIL REGIONAL AND GALINÉE PROJECTS
Montreal, August 24, 2023. Midland Exploration Inc. (“Midland” or th e “Corporation”) (TSX-
V: MD) is pleased to announce the start of a first exploration program for lithium mineralization on its
Mythril area and Galinée projects, operated by Rio Tinto Exploration Canada Inc. (“Rio Tinto”). The
Mythril Regional (Chisaayuu, Corvette and Mythril East ) and Galinée projects are under an option to
joint venture agreement with Rio Tinto since June 2023 (see Midland press release of June 14, 2023).
The projects are located in the Eeyou Istchee James Bay region close to Patriot Battery Metals Inc.'s
(“Patriot”) Corvette project and immediately east of Winsome Resources Ltd.’s (“Winsome”) Adina
project, respectively.
Highlights
• New prospecting campaign and LiDAR high resolution survey to begin;
• Lithium lake bottom anomalies were id entified on the Chisaayuu and Corvette projects
following statistical treatment;
• Close to Mythril Regional projects, a maiden resource estimate at Patriot’s CV5 spodumene
pegmatite returning inferred 109.2 Mt at 1.42% Li 2O (0.40% Li2O cut-off) (see Patriot’s
press release dated July 30, 2023);
• Along strike wit h the Galinée project , lithium mineralization continues to b e intersected by
Winsome on Adina, such as 1.37% Li2O over 61.2 m from 8.9m on its main zone , along
strike with the Galinée project (see Winsome’s press release dated August 1, 2023);
The Eeyou I stchee James Bay region is cur rently the focus of an explorat ion rush for lithium
pegmatites. The Mythril regional projects are located about between 12 and 50 kilometres of lithium
pegmatites discovered on Corvette as reported by Patriot. The Mythri l Regional projects consists of
730 claims totalling 370.1 square kilometres. The Galinée project is located about 4.0 kilometres east
of the lithium pegmatites discovered on Adina and reported by Winsome. The Galinée project consists
of 54 claims totalling 27.7 square kilometres.
Mythril Regional and Galinée Exploration Program for Lithium
The Mythril Regional projects Chisaayuu, Corvette and Mythril Eas t contain am phibolite rock
formations, the regionally common host rock bearing lithium pegmatites, and compilation of historical
work by Midland revealed strong eviden ce of Li -Be-Ta pe gmatite potential. While exploring for
copper on Chisaayuu in 2022, a pegmatite outcrop returned two strongly anomalous lithium values in
grab sa mples: 0.12% Li 2O and 0.04% Li 2O. Grab sample of a pegmatitic boulder on the Corvette
project also returned hig hly anomalous Li -Ta values: 0.02% Li 2O, 72 ppm Ta (see Midland’s press
release of February 7 , 2023). Furthermore, lake bottom lithium ano malies were i dentified on the
Chisaayuu and Corvette projects, following a regional statistical treatme nt of more than 23,000
analyses and completed by Midland (see Midland’s press re lease of March 6, 2023). On Chisaayuu,
these targets are located more to the west of the anomalous outcrop identified. None of these
anomalies have been followed up yet and will be targeted during the exploration program.
This Adina showing is located at the contact bet ween amphibolites of the Tri este Formation to the
south and felsic intrusives to the north. This contact is marked by a major structure that most likely
controlled the emplacement of pegmatites on the Adina showing. This same highly favourable contact
is present on Midland’s Galinée property over more than 7 kilometres and has never been explored for
lithium in the past. This suggests that the Galinée project sho ws potential for lithium exploration. The
maiden exploration program for lith ium will target t his structure by helicopter supported prospecting
and geological mapping . A high-resolution LiDAR survey covering all the pro jects to be explored is
also ongoing and will assist the exploration campaign in identifying pegmatites.
Cautionary statement:
Mineralization occurring on the Adina and Corvette projects held by Winsome and Patriot respectively
is not necessarily indicative of mineralization that may be identified on properties h eld by Mid land
discussed in this press release. Also note that grades f rom grab samples and erratic boulders are not
necessarily indicative of mineralized zones.
