ACTIVITIES SUMMARY:
• 5,353 oz Au produced at an average grade of 31.3 g/t Au (0.91 oz/t Au since the Company 's
acquisition of Tintic ("Acquisition") on May 27, 2022.
• Current underground test mining activities at Trixie are directed by the exploration sampling and
drilling results.
• Completed 7,315 m ( 24,000 ft.) of reverse circulation ( "RC") drilling and 1,274 m (4,180 ft.) of
diamond drilling since the date of the Acquisition, and four drill rigs currently in operation. Drill assay
results are pending.
• The underground sampling results and drillhole information will form the basis of an initial mineral
resource estimate, expected to be completed by the first quarter of 2023, to support near-term mine
planning and production.
• 500 m (1,640 ft.) of Trixie portal and ramp construction (~30% complete) to date. Once fully
complete, the decline will significantly improve access to the underground workings, expand and
increase underground operations.
• High-grade gold results are present throughout the entire sampled area, and along exploration
cross-cuts expanding the T4 structure up to 25 m (80 ft.) and parallel to T2 (see Figure 2).
• The mineralized structures remain open along strike and at depth and significant potential exists to
expand the known mineralization.
Chris Lodder, President of Osisko Development , commented, "The Trixie underground sampling
results cont inue to demonstrate continuity of high grades associated with the T2 structure with many
samples returning over 100 g/t gold. The recent exploration cross cuts exploring the T4 structure parallel
to the T2 have identified considerable mineralization to the east up to approximately 80 feet wide. Similar
high-grade gold telluride mineralization is also identified in the T4. Given these structures are open along
strike and down dip, we anticipate advancing our exploration efforts to these areas rapidly with four drill rigs
and ongoing advancement of the Trixie decline."

About Trixie
The Trixie test mine is one of several gold and base metal targets within the larger Tintic Project consisting
of 17,000 acres of patented mining claims and mineral leases within the historic East Tintic Mining District
of Central Utah , USA. The T2 and T4 structures at Trixie show multi -ounce gold grades associated with
high sulphidation epithermal mineralization, structurally controlled and hosted within quartzites. High grade
mineralized material from the T2 and T4 structures is currently being processed via vat leaching on site.
The T2 structure is approximately 0.3 m to 2.4 m (1 to 8 ft.) wide and mineralization consists of native Au,
and rare Au-Ag – rich telluride minerals with quartz. The T4 is a mineralized stockwork zone ranging from
approximately 3 m to 25 m (10 to 80 ft.) and located in the hanging wall of the T2 and is comprised of Au-
Ag rich mineralization in host rock quartzite with quartz-barite-sulphosalt stockwork veining. Mineralization
currently defined over 220 m (720 ft.) in strike and reports consistent multi -ounce gold grades along the
entire strike length.
Face Sampling Methodology
As most structures at Trixie are steeply dipping to the east or west, current sampling procedures are
designed to sample the structure. Chip samples are collected and do not exceed 1.0 m (3 ft.) in length. The
face is washed for safety, and for better identification of mineralization, alteration and structures. The

hanging wall and footwall of the structures are marked up on the face and back, samples intervals are
marked up and follow lithological contacts.

Qualified Persons
The scientific and technical information contained in this news release has been prepared in accordance
with NI 43 -101, and has been reviewed and approved by Maggie Layman, P.Geo., Vice President,
Exploration of Osisko Development, and a "qualified person" within the meaning of NI 43-101.
Quality Assurance (QA) – Quality Control (QC)
True width determination is estimated to be approximately 0.3 m to 2.4 m (1 to 8 ft.) wide for the T2 structure
and approximately 3 m to 25 m (10 to 80 ft.) for the T4 mineralized stockwork zone located in the hanging
wall of the T2 structure. All underground face samples are collected by TCM geologists from each of the
active mining faces, with samples transported by the geologists from Trixie to the on -site TCM laboratory
located at the Burgin administrative complex. Underground samples are dried, crushed to <10 mm and a
250 g split is taken. The split is pulverized, and a 30 g Fire Assay with gravimetric finish is completed to
determine gold and silver grades, reported in oz/short ton and g/t.
The TCM Burgin laboratory is not a certified analytical laboratory, but the facility is managed by a qualified
Laboratory Manager with annual auditing by technical staff. Inter -laboratory check assays using ALS
Laboratory as a thi rd-party independent analysis of samples is routinely carried out as part of ongoing
Quality Assurance-Quality Control ("QA/QC") work. Certified OREAS QC standards and blanks are inserted
at regular intervals in the sample stream to monitor laboratory performance.
All drill core and exploration samples are dispatched to ALS Laboratory for offsite sample preparation and
analysis. Samples are assigned a unique sample ID. All geological and sampling information is entered into
Datamine Fusion database. Core i s sawn in half and half are sampled. Certified standards and blanks
inserted into all sample dispatches. Samples are collected by Old Dominion Transportation and dispatched
to ALS Laboratory in Reno, NV. Sample submission forms accompany the samples, and d igital copies
emailed to ALS.
All sample preparation is completed by ALS, including crushing and pulverizing (Prep31) of samples.
Analytical assays include gold and silver by fire assay of 50 g sample with AAS finish (Au-AA26), over limits
by gravimetric analysis (Au-Grav22). Multi element analysis is by four acid digest (ME -MS61). The pulps
are returned to Osisko Development and coarse rejects are disposed after 90 days. Assays are reported
Page 8 of 9
to Osisko Development, and then loaded into Datamine Fusion, QA/QC samples are checked, and assays
merged with sample information for future reporting.
Cautionary Statements
The Company cautions that the decision to commence small-scale underground mining activities and batch
vat leaching at the Trixie test mine has been made without the benefit of a feasibility study, or reported
mineral resources or mineral reserves, demonstrating economic and technical viability, and, as a result
there may be increased uncertainty of achieving any particular level of recovery of materi al or the cost of
such recovery. The Company cautions that historically, such projects have a much higher risk of economic
and technical failure. There is no guarantee that production will continue as anticipated or at all or that
anticipated production co sts will be achieved. The failure to continue production may have a material
adverse impact on the Company's ability to generate revenue and cash flow to fund operations. Failure to
achieve the anticipated production costs may have a material adverse impact on the Company's cash flow
and potential profitability. In continuing current operations at Trixie after closing, the Company will not be
basing its decision to continue such operations on a feasibility study, or reported mineral resources or
mineral reserves demonstrating economic and technical viability. The Company cautions that mining at
Trixie could be suspended at any time.
The Company is subject to the reporting requirements of the applicable Canadian securities laws, and as
a result reports information regarding mineral properties, mineralization and estimates of mineral reserves
and mineral resources, including the information in the Tintic Technical Report and this news release, in
accordance with Canadian reporting requirements, which are govern ed by NI 43 -101. As such, such
information concerning mineral properties, mineralization and estimates of mineral reserves and mineral
resources, including the information in the Tintic Technical Report and this news release, is not comparable
to similar information made public by U.S. companies subject to the reporting and disclosure requirements
of the SEC.
