Midland and RIO Tinto Extend the Santos Ni-Cu Zone and Plan to Drill-Test New Targets at Depth
MIDLAND AND RIO TINTO EXTEND THE SANTOS NI-CU ZONE AND PLAN TO
DRILL-TEST NEW TARGETS AT DEPTH
Montreal, October 12, 2023. Midland Exploration Inc. (“Midland”) (TSX -V: MD) is pleased to
report new nickel-copper (“Ni-Cu”) assay results from a drilling campaign completed to follow up on
the new Ni -Cu discovery named Santos, announced las t Apri l on the Tête Nord property . This
property is currently w holly owned by Midland but is subject to an option agreem ent with Rio Tinto
Exploration Canada Inc. (“RTEC”) since December 2021 and is l ocated near the town of La Tuque,
Quebec (see press release by Midland dated December 2, 2021).
In July 2023, a shallow drill hole was completed on the Sa ntos zone to investigate the thickness of the
Ni-Cu zone discovered la st April in drill ho le MDLD0015 which had reported 0.45% Ni and 0.18%
Cu over 10.37 metres (see press release by Midland dated April 27, 2023).
After having traversed 11.66 metres of overburden, d rill hole MDLD0018 intersected a mineralized
zone grading 0.33% Ni and 0.12% Cu over 39.73 metres from 11.66 to 51.39 metres downhole
depth, approximately 50 metres west of drill ho le MDLD0015. The interval exhibits impressive
magmatic breccias with decimet re-scale semi-massive sulphide zones, indicati ve of a dy namic
magmatic system at Santos. The t wo drill holes, MDLD0015 and MDLD0018, began directly in the
mineralized zone; the tot al thickness of this zone has yet to be determined and the zone remains open
in all directions.
The next drilling campaign, set to begin in November 2023 when permits are received, will consist of
four (4) additional drill holes totalling 1,150 metres and will mainly focus on new targets identified at
depth following downhole and ground-based electromagnetic surveys completed in the summer of
2023.
The best mineralized i ntervals intersected in drill hole MDLD0018 are summarized in the following
table.
Drillhole MDLD0018
From (m) To (m) Width (m) WtAve Ni% WtAve Cu%
11.66 51.39 39.73 0.33 0.12
Including 11.66 22.12 10.46 0.42 0.17

Including 47.93 48.35 0.42 1.16 0.37
The discovery hole MDLD0015 was initially designed to test a VTEM anomaly as well as an off-hole
anomaly detected in drill hole MDLD0009; it 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 hole intersected 1.10% Ni and 0.71% Cu over 2.68 metres. Further down, from
33.02 to 43.39 metres, a mineralized int erval graded 0.45% Ni and 0.18% Cu over 10.37 metres (see
press release by Midland dated April 27, 2023).
Regionally, th e new Santos Ni-Cu zone is favourably lo cated a long a N -S-trending structure,
approximately 8 kilometres north of the former Lac Edouard Ni-Cu mine.

About the Tête Nord Ni-Cu property
The Tête Nord property covers mafic and ultramafic rocks of the La B ostonnais Complex north of La
Tuque, w hich ho sts the former L ac Edouard mine that historica lly prod uced 50,000 tonn es of ore
grading 1.50% Ni and 0.50% Cu (source: SIGEOM NTS sheet 31P09).
This property hosts a few mineral occurrences, including the Savan e showing located approximately
25 kilometres south of the fo rmer Lac Edouard mine. This Ni -Cu show ing was discovered by
prospecting in 1995 when grab samples collected in a pyroxenite yielded historical values of 1.80% Ni
and 0.20% Cu. Another grab sample from a subcropping boulder also yield ed grades of 1.98% Ni and
0.46% Cu about 250 metres n orth of the Savane showing (Source: SIGEOM NTS sheet 31P07;
GM55352).
James Bay Option Agreement – First cash payment received
Moreover, Midland reports that the first cash payment of 500,000$ (CAN) for the James Bay option to
joint venture agreement with RTEC was received on October 4, 2023.
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 available;
intervals are thus reported in core length.
Mineralization occurring at the former Lac Edouard min e is not necessari ly i ndicative of
mineralization that may be found on the Tête Nord property held by Midland in partnership with
RTEC.
Quality Control
Drill core samples were sent to ALS Thunder Bay for preparation and ALS Vancouver for analysis.
Samples were prepared by the RIORCK package where the entire sample is crushed to 70% less than
2mm using a Boyd crusher -splitter combination, then 1kg of material is pulverized to better than 85%
passing 75 microns. This method includes bet ween-sample washes on both the crushers
and pulverizers. The samples were analyzed for a full element suite using lithium borate fusions (ME -
ICP06 and ME-MS81), four acid digestions (ME-4ACD81), S and C by induction furnac e (ME-IR08)
and Au-Pt-Pd by an ultralow detection 30g fire assay (PGM -MS23L). The MDLD0018 batch of 59
samples included 3 CRMs, 2 blanks, and 2 core duplicates for a QC insertion rate of 13%. The
certified reference materials were in -house standards TAM26 and TAM28 , all independently
manufactured and independently certified , and a commercial standard OREAS 86 . ALS included
laboratory QC of a range of blank and CRM materials, and 7 RTX samples wer e analyzed twice as
pulp duplicates.
