MIDLAND EXPANDS ITS PATRIS PROPERTY AND ACQUIRES STRATEGIC POSITION

FOR GOLD AND LITHIUM IN ABITIBI

Montreal, February 22, 2023. Midland Exploration Inc. (“Midland’ or the “Corporation”) (TSX-

V: MD) is pleased to announce the acquisition by map designation of 10 0% interest in a n important

strategic land position for its gold and lithium potential in southern Abitibi, Quebec. This new

acquisition adjacent to the east of Midland’s Patris gold property , consists of 133 claims (74 square

kilometres) and is located approximately 60 kilometres northwest of the town of Val-d’Or.

This land position covers more than 25 kilometres of turbiditic sedi ments of the Lac Cast e Formation,

immediately to the sout h of the M anneville-North Fault, which is a subsidiary of th e pro lific gold-

bearing Destor-Porcupine Break. These turbidites are intruded by dioritic dyke swarms, as well as the

western edge of the La Motte Batholith. To the south, Lac Caste sediments are in contact with

ultramafic ro cks of the La Motte -Vassan Form ation, where a major deformation zone (Manneville-

South Fault) can be traced over more than 10 kilometres.

These new cl aims are also located approximately 15 kilometres we st of the Authier lithium dep osit,

and approximately 45 kilometres west of the LAN li thium depos it, both held by Sayona Mining

Limited (“Sayona”). The LAN deposit hosts measured and indicated mineral resources (NI 43-101) of

73,675,000 tonnes grading 1.05% Li2O and inferred resources of 28,246,000 tonnes grading 1.08%

Li2O. The Authier deposit hosts measured and indicated mineral resources (NI 43 -101) of

14,140,000 tonnes grading 1.01% Li2O and inferred mineral resources of 2,996,000 tonnes grading

1.00% Li2O. (Source: Sayona press release dated March 1 , 2022; Please refer to Table 1 for mi neral

resources details).

Midland’s new strate gic position cover s, o ver more than 10 kilometres, the La Motte -Vassan

Formation consisting of mafic and ultramafic rocks, which hosts lithium p egmatites at the Authier

deposit. These new claims also cover the west and north edges of the La Motte Bat holith. The latter,

along with the La Corne Batholith, both composed of gr anodioritic and monzonitic phases, occupy a

central position relative to the main lithium occurrences known in this area north of Val-d’Or.

Midland is curr ently planning a high -resolution ma gnetic survey in order to map in greater detail

subtle mag netic fe atures as well as any structure s that could cro sscut the ultramafic rock s and h ost

spodumene-bearing pegmatite intrusions.

Cautionary statement
