MIDLAND DISCOVERS AN IMPORTANT GOLD-ZINC-SILVER MINERALIZED SYSTEM

ON ITS CANIAPISC AU PROJECT, JAMES BAY

Montreal, September 09, 2025. Midland Exploration Inc. (“Midland”) ( TSX-V: MD) is pleased to

announce the recent discovery of a major gold -zinc-silver mineralized system on its Caniapisc Au

project. The Caniapisc Au project is wholly owned by Midland and consists of 296 claims (EER)

covering an area of 146 square kilometres.

Highlights:

• Several important clusters of Au-Zn-Mn-Ag and Au-Zn-Ag-(Pb)-bearing boulders coinciding

with extensive Au-Zn anomalies in soils;

• Eight (8) rock samples (boulders) with gold values above 1.00 g/t Au (max of 14.3 g/t Au); 5

rock samples (boulders) with zinc values above 1% Zn (max of 4.5% Zn);

• Twenty-seven (27) soil samples with values above 10 ppb Au, including 6 soil samples with

values greater than 100 ppb Au (max of 423 ppb Au);

• Thirty-four (34) rock samples (boulders) with gold values above 0.10 g/t Au;

• Diverse metal assemblages - Au-Zn-(Pb), Au-Zn-Mn, Cu-Mo-Au-Ag, Au-Cu, Au only – in

distinct lithologies, suggesting several distinct gold sources and a fertile environment for Au;

• Acquisition by map designation of 201 new claims (EER) along the periphery of the Caniapisc

Au gold property;

• The 2024 till program confirmed historical gold anomalies with up to 100 gold grains per

10 kg of till (November 14 , 2024 Press release and 2014 report; GM 67959 Ministry of Natural

Resources and Forest)

A ten (10) -day geological reconnaissance campaign was conducted last June on the Caniapisc Au

project. The main objectives of this campaign were to explain several Au -Zn-Pb-Mo anomalies

discovered in 2024 (November 14, 2024 Press release ) to conduct our first geological assessment of its

gold potential, and to carry out a prospecting campaign and a soil survey covering most of the project

area. A total of 159 rock samples and 318 soil samples (B horizon) were collected.

2025 Rock Sampling Results

Within a 2-kilometre radius up-ice from historical gold anomalies in tills (2014 report; GM 67959 Ministry

of Natural Resources and Forest ), prospecting efforts successfully identified boulder fields (with

subangular to angular boulders) and outcrops showing anomalous values for Au and various other metals

(Zn, Mn, Pb, Cu, Mo, Ag). Very few outcrops are present within the project area; boulder prospecting

thus becomes a valuable tool in this type of environment. Out of a total of 159 isolated samples (grab

samples) collected during this campaign , 8 yielded gold values above 1.00 g/t Au , including a

maximum value of 14.3 g/t Au , and 34 samples yielded gold values between 0.10 and 1.00 g/t Au

(Table 1). Five (5) grab samples (rocks) also yielded zinc (Zn) values above 1% (max 4.5% Zn). The

same five (5) samples also exhibited high manganese (MnO) values reaching up to 7.67% MnO. All of

the 2025 samples with anomalous gold and zinc values were collected in boulders (figure 3 to 6).

Gold Results from the 2025 Soil Survey

Gold results for the 318 soil samples (B horizon) collected on the property include 6 values greater than

100 ppb Au (max = 423 ppb Au), 1 value between 50 and 100 ppb, and 20 values between 10 and 50 ppb.

An extensive anomaly (around a lake in the south part of the project) is characterized by an Au-Zn-Mn

signature. Four (4) other strong anomalies in soils (Au-only) are also present within the survey area

(Figure 7).

Metal Assemblages in Rocks

Sampling conducted in 2024-2025 in this area led to the identification of several distinct metal

assemblages in boulders and outcrops (Table 2). Many boulders exhibit gold-zinc-silver-lead (Au-Zn-

Ag-Pb), gold-zinc-manganese-silver (Au-Zn-Mn-Ag), or copper-molybdenum-gold-silver (Cu-Mo-Au-

Ag; boulders and outcrops) assemblages. Au-Zn-Ag-Pb and Au-Zn-Mn-Ag boulders are, for the most

part, located near a lake in the south part of the project area (Figure 4), and their origin is deemed local,

within the immediate vicinity, based on the distribution of boulders and coinciding soil anomalies. The

five (5) samples grading above 1% Zn are located in this area (max 4.5% Zn). Au-Zn-Mn mineralization

(which yielded the highest Zn grades ) is associated with very strong calc -silicate alteration (+Ca-Fe-

Mg-Si, amphibole-garnet-calcite in descriptions) accompanied by nearly complete Na-K leaching.

Numerous other gold-bearing boulders sampled in various parts of the project exhibit metal assemblages

different from these Au-Zn-Ag-Pb, Au-Zn-Mn-Ag and Cu-Mo-Au-Ag assemblages (Table 2), namely

including Au-Cu and Au -dominant assemblages, which likely indicate distinct sources of gold. In

particular, an amphibolite boulder with potassic alteration located approximately 800 metres east of the

Au-Zn-Mn boulders graded 14.3 g/t Au. Another amphibolite boulder with strong potassic alteration

(fuchsite), located more than 3 kilometres northeast of the Au-Zn-Mn boulders, graded 2.87 g/t Au with

anomalous As values (the only As anomaly in the area). The source of these boulders has n ot yet been

located and is considered distinct from Au-Zn-Ag (Mn -Pb) and Cu-Mo-Au-Ag boulders. A highly

angular boulder of amphibolite with quartz veining, located in the west part of the project, graded

3.29 g/t Au, 0 .67% Zn, 0 .12% Pb, 0 .05% Cu and 6.7 g/t Ag . This boulder is located near an

amphibolite outcrop that also exhibits anomalous Au, Zn and Pb values and as such, is considered of

local origin and a high-priority target for follow-up.

The very strong ly similar alteration assemblages associated with Au-Zn-Mn and Cu -Mo signatures

suggest they may represent the same mineralization system. The Cu-Mo signature is most certainly

magmatic-hydrothermal (associated with felsic intrusions), indicating the Au-Zn-Mn mineralization is

likely related to this system as a more distal facies. The remarkable intensity of the calc-silicate alteration

suggests skarn-type mineralization, as well as the possibility that extreme calcium enrichment may be

explained by calcium-rich protoliths. Zn-Mn mineralization is fairly typical in zinc-rich skarn settings.

New Exploration Program

Midland is pleased to announce the acquisition, by map designation, of 201 new claims along the

perimeter of its Caniapisc-Au gold property, wholly owned by Midland.

A 10-day exploration program will be conducted in the coming weeks on the Caniapisc Au project. This

program will include geological mapping combined with prospecting, as well as an extensive soil

sampling program to cover areas that were not covered during the previous phase as well as the new

EER recently acquired on the project. A total of 200 soil samples will be collected at a 200-metre spacing

along grid lines spaced every 400 metres. A tighter spacing is planned in the vicinity of new gold

anomalies in soils.

About the Caniapisc Au Project

The Caniapisc Au project lies south of the Caniapiscau Reservoir and is geologically located within

the Ashuanipi Subprovince, a lesser known and explored portion of the Archean Superior Province.

The project is more specifically located in the Raynouard Complex, charac terized by a 50 kilometre-

long volcanosedimentary belt comprising bimodal volcanic sequences, metasedimentary rocks and

iron formations. Historical exploration work, to the south of the Caniapisc Au project, highlights the

potential of the Ra ynouard Complex with the presence of volcanogenic Cu -Zn-Ag-Au and porphyry

Cu-Au-Ag-Mo mineralization. The Caniapisc Au project is strategically located north of these

showings, where a historical 2014 till sampling survey identified gold anomalies. Three (3) till samples,

located within the perimeter of the project, returned up to 41 pristine, 66 modified, and 9 remodel ed

gold grains, which to our current knowledge have not been followed up extensively.

Quality Control

Rock samples from the project were analyzed at Actlabs laboratories in Ancaster, Ontario, by ICP-MS

with 4-acid digestion for metals, and by standard fire assay on 30-gram fractions with atomic absorption

finish for gold and by ICP-OES fusion for major elements (including MnO). Soil samples are processed

and analyzed at Actlabs laboratories in Ancaster, Ontario, by neutron activation (namely for Au) and

ICP-OES with 4-acid extraction (namely for Zn and Mn), after sieving to -177 microns. Exploration

programs are designed, and results are interpreted by Qualified Persons employing a Quality

Assurance/Quality Control program consistent with industry best practices, including the alternate use

of standards and blanks for every 20 samples.

Cautionary statements

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

Mineralization occurring at deposits and showings mentioned in this press release is not necessarily

indicative of mineralization that may be found on projects held by Midland and mentioned in this press

release.
