Winshear Reports Regional Scale GOLD Geochemical Anomaly at the Thunder BAY GOLD Project, Ontario
WINSHEAR REPORTS REGIONAL SCALE GOLD GEOCHEMICAL ANOMALY AT THE THUNDER BAY
GOLD PROJECT, ONTARIO
Vancouver, September 22, 2025
Winshear Gold Corp. ("Winshear" or the "Company") (TSXV:WINS) provides new geochemical
results from reconnaissance mapping , prospecting and basal till geochemical sampling at the
Thunder Bay Gold Project (TBGP’), NW Ontario.
Numerous areas for follow up have been identified, the most prominent of which is the discovery
of a six kilometre-long series of anomalous gold-in-till samples named ‘Inflection’, which is
located in the central / southern part of the project area (Maps 1, 2).
Winshear’s CEO, Richard Williams, stated “Results from the initial reconnaissance geochemical
survey at TBGP are very encouraging, and confirm management’s belief that the magnetic and
structural character of the project reflects a highly prospective exploration environment. The
Inflection Target, in particular , has a large footprint and is located directly over an area where
several major structures converge. We will now commence more detailed soil geochemistry and
an airborne magnetic survey to vector toward the bedrock source(s) of the anomalies.”
TARGETS FOR FOLLOW UP
Inflection
The Inflection target represents a newly discovered gold anomaly with up to 44ppb Au in till
samples. The area covers the intersection of several east-southeast and west-southwest trending
structures and contains a complex mix of felsic to intermediate volcanics, clastic metasediments,
and komatiitic ultramafic rocks. Historic mapping in the area has noted abundant stockwork
quartz veining in felsic volcanic rocks. This area has not seen any significant historic exploration,
and is a priority target for the Company
El Dorado
Located in the eastern section of the project area, rock and till geochemistry returned modest
gold, silver and copper values that warrant further follow up. Historic sampling by Ontario
Geological Survey has returned up to 36.3 G/t Au in arsenopyrite bearing quartz veins in this area
(Ontario Mineral Deposit database MDI152A10SW00032).
Central and Northern Areas
Anomalous gold in till samples were found in the central and northern parts of the project area,
where sampling density is very low. These targets are located close to strong structural
lineaments as seen in the magnetic response. Government mapping in these areas is sparse.
Additional sampling is being planned in a follow-up program to flush-out the extent and source
of these anomalies.

Map 2. Sample 1298568 shows a distinct ultramafic signature, with 267ppm Ni, 933ppm Cr and 3.86% Mg and
potentially Cu-Ni-PGE signature with 186ppm Cu, 11ppb Au and 51ppm Co. with 267ppm Ni, 933ppm Cr and
3.86% Mg and potentially Cu-Ni-PGE signature with 186ppm Cu, 11ppm Au and 51ppm
Additional technical information is provided in the Appendix.
Proposed Phase II exploration program
A geochemical sampling program consisting of the collection of approximately 150 till samples,
600 B horizon soils, and 250 prospecting samples will commence in the next two weeks.
Drone based airborne magnetic surveys are also being considered for the Inflection target and
the El Dorado target areas, in order to improve the structural understanding of the area and for
future exploration follow-up.
Overview of the Thunder Bay Gold Project
• Eastern extension of the Archaean age Shebandowan greenstone belt;
• Very little historic exploration conducted in the Thunder Bay Gold Project area;
• Potential for orogenic gold, volcanogenic massive sulphides, and nickel –copper–cobalt
sulphide deposits;
• Evidence of geological structural setting similar to other gold-endowed Abitibi greenstone
belts in Ontario (Map 3).
• Historic reports indicate the presence of high -grade gold mineralization (>1 oz/T Au) at
the Gold Hill and Eldorado prospects (described below).
Map 3. Total field magnetic plot (OGS 1991 data) showing regional structural architecture including the Thunder Bay
Fault, Kingfisher Fault and associated bridging structures. Magnetic low anomalies coincide with some of the regional
structures, interpreted as possible magnetite destruction from hydrothermal alteration and considered indicative of
a large scale orogenic gold system.
The Kingfisher Fault ( Shebandowan Structural Zone ) is a major, deep -rooted crustal structure
that locally forms the northern margin of the Shebandowan greenstone belt and is in contact
with the Quetico metasedimentary domain to the north. It is spatially linked to Timiskaming-like
fault-bounded basins and arcuate greenstone belts . The Shebandowan area contains typical
greenstone-belt assemblages, including volcanic sequences (mafic to ultramafic/komatiitic flows
and sills), intercalated clastic sedimentary rocks and granitoid intrusions. Structurally, rocks are
locally highly sheared and folded.
As the Shebandowan structural zone has experienced long lived repeated brittle -ductile
reactivation, it is considered to be an important control on mineralizing fluids. The Shebandowan
region has a history of exploration for gold and base metals (komatiite -hosted and structurally
controlled styles). Current exploration projects and historic working in the region have targeted
shear-zone hosted gold near structural breaks and intrusive contacts.
Mines in the Shebandowan belt include INCO’s Shebandowan nickel – copper – PGE mine that
was in production from 1972 to 1998. The Mine Produced 9.29 Mt at grades of 1.75% Ni, 0.88%
Cu, and 1.83 g/t PGE. Exploration by INCO over that period focused primarily on Cu -Ni-PGE
deposits.
Other companies working in the belt, include Delta Resources (TSX-V: DLTA) who are exploring
the Eureka Gold Zone, a gold target that measures 2.5 km long, 10–100 m wide, and at least 300
m deep. The gold mineralization is hosted in stockwork veinlets of quartz-ankerite-pyrite within
a broad alteration zone of ankerite, calcite, silicification and albitization. Higher grade intercepts
include 5.92 g/t Au over 31m and 1.79 g/t Au over 128.5m.1
GoldX2 (TSX-V: AUXX) is advancing its Moss Gold Project which has an Indicated Mineral Resource
Estimate of 1.535 million ounces grading 1.23g/t Au and Inferred Mineral Resource Estimate of
5.198 million ounces grading 1.11g/t Au, toward a production decision. 2

Sampling Procedures
The procedure for till sampling was: collection of till samples using pickaxes and shovels to
excavate a hole deep enough to expose unweathered material and determine if it was basal till
before an approximately 3kg sample was collected. Samples were stored at the contractors
secure warehouse facility before being transported by the contractor staff to the Actlabs
laboratoy in Ancaster, Ontario.
The company is relying on Actlabs QA/QC protocols for this first pass reconissance geochemical
surveys. Internal QA/QC procedures to include some gold standards into the soil sample streams
are being considered for the next stage geochemical surveys.
Samples were analysed for gold using Actlabs‘ 1A2 fire assay method using a 30g sample and a
detection limit of 5ppp Au. Multi-element analysis was conducted using Actlabs‘ 1E3 method –
ICP-OES (inductively couple plasma optical emission spectroscopy), providing results for 38
elements, including silver, arsenic, cobalt, copper, molybdenum, nickel, lead, antimony and zinc.
