MIDLAND IN PARTNERSHIP WITH RIO TINTO CONFIRMS HIGH-GRADE LITHIUM

UP TO 7.2 % LI2O AND IDENTIFIES ADDITIONAL SPODUMENE-BEARING

PEGMATITES ON GALINÉE PROJECT

Montreal, November 2, 2023. Midland Exploration Inc. (“Midland”) (TSX-V: MD), in partnership

with Rio Tinto Exploration Canada Inc. (“RTEC”), is pleased to provide new assay results and an

update on complet ed and upcoming work following the identification of a series of spodumene -

bearing pegmatite dykes on the Galinée project, approxim ately 8 kilometres east of the Adina lithium

deposit held by Winsome Resources (“Winsome”) (see press release by Midland dated September 19,

2023). The Galinée project is currently wh olly owned b y Midland and is subject to an option

agreement signed with RTEC in June 2023 (see press release by Midland dated June 14, 2023). Field

crews began working on Galinée following the complete lift of access restrictions in the James Bay

region as a result of forest fires in the summer of 2023 . The field program, which began near the end

of August and lasted until October 12 th, also included w ork on other projects under the same option

agreement such as Corvette, Chisaayuu and Mythril East.

Highlights:

• Spodumene-bearing pegmatite dykes identified over at l east 600 metres strike leng th at

Iceberg Showing with high-grade grab samples grading up to 7.2 % Li2O;

• New additional spodumene-bearing ou tcrops found 500 m etres so uth and 900 metres

southwest from Iceberg;

• LiDAR survey completed on Galinée, Chisaayuu, Corvette and Mythril East;

• High resolution MAG-RAD survey completed on Galinée;

• Drilling planning in progress on Galinée.

Assay results have been received for the 26 samples collected at the Iceberg lithium discovery. High-

grade grab samples returned up to 7.2 % Li 2O, including 6 samples grading between 5.0 % Li2O

and 7.2 % Li2O, 6 sa mples grading between 3.0 % Li2O and 5.0 % Li2O, and 3 other samples

grading between 1 % Li2O and 3 % Li2O. The other samples returned anomalous lithium values

below 1% Li2O.

The Iceber g discov ery was identified on several outcrops by fie ld crews after a few days of

prospecting. A combination of ultraviol et (UV) lamp and a LIBS (Laser-Induced Breakdown

Spectroscopy) analyzer were used to confidently identify spodumene, including some crystals

reaching up to 60 centimetres in length (see press release by Midland dated September 19, 2023). The

Iceberg discovery consists of a series of spodumene exposures outcrop , now over a 600m east -west

strike intermixed with amphibolite and gra nodiorite. Testing subtle lo cal r elief features in area s

covered with vegetation and soil resulted in locat ing two new coarse spodumene -bearing pegmatite

outcrops, located 500 and 900 metres south and sou thwest from the Iceberg showing. Assays are

pending.

The G alinée project is located approximately 4 kilometres due east of the Adina showing held by

Winsome. This showing is located at the contact between amphibolites of the Trieste Formation to the

south and f elsic int rusives to the north. This contact is marked by a major st ructure tha t likely

controlled the emplac ement of pegmatites at the A dina showing. This new discovery, on Galinée, of

spodumene-bearing pegmatite dykes was made along the same highly favourable contact zone, which

is present on the pr operty over more than 7 kilometres and which has never been explored for lithium

in the past. This first exploration program included prospecting, geological mapping as well as a high-

resolution LiDAR survey. Following the discovery, a high -resolution airborne magnetic and

radiometric survey was com pleted. The LiDAR, imagery, magnetic and radiom etric data will

hopefully guide future work to expand the footprint o f s podumene outcrops on Galinée. A maiden

drilling campaign is currently being planned on Galinée.

Initial exploration work on Chisaayuu, Corvette and Mythril East blocks was successful in identifying

several pegmatites. No lithium phases were obse rved so far, but g eochemistry of these pegmatites is

underway to determine their full potential and for further vectoring.

Cautionary statements

Grab samples are selective by nature and may not be representative of mineralized zones.

Lithium m ineralization occurring at Winsome’s Adina deposit is not necessarily indicative of

mineralization that may be encountered on the Galinée project held by Midland.

Quality Control

Samples were analyzed by ALS Geochemistry laboratories using a major element fusion, trace

element fusion and ultratrace four acid digest m ethod (ME -ICP06, ME -MS81 and ME -MS61L

methods). Samples reporting >4500 ppm Li on the four acid digest method were reanalyzed by a

sodium peroxide fusion method specific for hard rock lithium (Li-ICP82b).

In this batch of 26 primary samples, RT EC included one quartz blank and two commercial CRMS

(OREAS 751 and OREAS 753). ALS included four in-lab duplicate analyses and 31 additional CRMs.
