MIDLAND IN PARTNERSHIP WITH RIO TINTO IDENTIFIES NEW TARGETS AND

RESUMES DRILLING ON THE NEW SANTOS NICKEL-COPPER ZONE, TÊTE NORD

PROJECT

Montreal, July 4, 2023. Midland Exploration Inc. (“Midland”) (TSX -V: MD) is pl eased to

announce that work will resume in the vicinity of the recent nickel-copper (“Ni-Cu”) discovery named

Santos. This zone was discovered during the maiden drilling program completed by Rio Tinto

Exploration Canada Inc. (“RTEC”) on the Tête Nord property. The upcoming drilling program will

begin shortly to test new prospective geophysical targets located near Santos as well as further south in

the vicinity of the Palmeiras and Savane showings.

Located near the town of La Tuque, Quebec, t he Tête Nord property is currently wholly owned by

Midland but is subject to an option agreement with R TEC since December 2021 (see press release by

Midland dated December 2, 2021).

Highlights:

• Commencement of a new drilling program with 6 drill holes totalling up to 1,900 metres;

• Several new drillin g targets identified in t he Santos and Pal meiras areas, north of the

former Lac Edouard Ni-Cu mine;

• New drilling targets at Savane.

New drilling targets at Santos and Palmeiras

Over the past few months, ground-based gravity surveys were completed in the vicinity of the new

Santos Ni-Cu zone and further south along the same N-S-trending structure, in the vicinity of the

Palmeiras sho wing. The gravity survey led to the identification of n ew prospective drilling targets ,

favourably located near the two showi ngs. Thi s ne w dri lling campaign will consist of six ( 6) drill

holes totalling up to 1,900 metres and is scheduled to begin in early July, depending on the forest fire

situation in this part of the province of Quebec.

During the maiden drilling program, drill hole MDLD0015, designed to test a VTEM anomaly and an

off-hole anomaly detected in drill hole MDLD0009, intersected from 14 metres to 80 metres downhole

depth, several layers with Ni -Cu mineralization within altered gabbro horizons. From 20.11 to

22.79 metres, the drill hol e intersected 1.10% Ni and 0.71% Cu over 2.68 metres. Further down,

from 33.02 to 43.39 m etres, a mineralized interval graded 0.45% Ni and 0.18% Cu over

10.37 metres (see press release by Midland dated April 27, 2023). Regionally, this new Santos zone is

favourably l ocated along a N-S-trending structure, approximately 8 km north of the former Lac

Edouard Ni-Cu mine.

Modelling of the ground gravity survey completed this summer in the Santos area led to the

identification of a new anomaly located a few hundred metres northwest of the Santos zone. A total of

three (3) drill holes totalling up to 900 metres will be completed in the Santos area. Two of these drill

holes will test possible extensions of the Santos zone to the south and west , and the third drill hole

will be collared northwest of Santos to test the new gravity anomaly.

Approximately two kilometres south of Santos, along the same N-S-trending structure, a large gravity

anomaly was detected immediately north of the Palmeiras showing, where mineralized Melagabbro to

pyroxenite outcrops were identified near VTEM anomalies. One (1) drill hole totalling up to 300

metres is planned to test this new geophysical target.

Additional drilling on the Savane showing

A gravity survey was a lso completed in the Savane showing area. During the maiden drilling

campaign, a mineralized interval intersected in drill hole MDLD0001 graded 1.07% Ni and 0.13% Cu

over 0.78 metre, from 101.87 to 102.65 metres. Modelling of the gravity survey resulted in a better

definition of the geometry of the mineralized intrusion at Savane and the identification of two lobes

possibly repr esenting pr eviously unknown parts of the mineralized int rusion. Two (2) drill holes

totalling up to 700 metres will be completed to test these intrusive targets.

In addition, prospecting work will be conducted approximately 750 metres northwest of the Savane

showing, to explain the presence of a new gravity anomaly like the one associated with the

mineralized intrusion at the Savane Ni-Cu showing.

About the Tête Nord Ni-Cu property

The Tête Nord property covers mafic and ultramafic rocks of the La Bostonnais Complex north of La

Tuque, which hosts the former Lac Edouard mine that historically produced 50,000 tonnes of ore

grading 1.50% Ni and 0.50% Cu (source: SIGEOM NTS sheet 31P09).

Cautionary statements:

Note that grab sample grades may not be representative of mineralized zones.

The true thickness of reported intervals cannot be determined with the information currently availa ble;

intervals are thus reported in core length.

Mineralization occurring at the former Lac Edouard mine is not necessari ly i ndicative of

mineralization that may be found on the Tête Nord property held by Midland.

Quality Control

Drill core samples were s ent to ALS Thunder Bay for preparation and ALS Van couver for analys is.

Samples were prepared according to the RIORCK package, where the entire sample is crushed to 70%

passing less than 2 mm using a Boyd crusher -splitter combination, then 1 kg of material is pulverized

to at least 85% passing 75 microns. Thi s method includes between-sample washes on both crushers

and pulverizers. Samples were analyzed for a full element suite using lithium borate fusion (ME-

ICP06 and ME-MS81), with four-acid and aqua regia digestion (ME-MS61L and ME-MS41L), S and

C by induction furnace (ME-IR08) and Au-Pt-Pd by ultralow detection 30 g fire assay (PGM-MS23L).

The MDLD0015 batch of 114 samples included 8 certified reference materials (CRM) and 13 blanks,

as well as 4 core duplicates for a quality control insertion rate of 28%. Reference materials consist of

in-house standards CL -LG, CL -HG and EA -M, all independently prepared and certified. ALS

included laboratory quality control using a range of blank s and CRM standards, and 16 RTX samples

were analyzed twice as duplicates.
