UPDATE ON THE MOSSEAU DRILL PROGRAM AND DETAILS OF NEW FALL, 2025
EXPLORATION PROGRAM
Vancouver, British Columbia / October 3, 2025 - Harvest Gold Corporation (TSXV: HVG)
(“Harvest Gold” or the “Company”) is pleased to announce the latest update on the drill program
at Mosseau , its flagship property in the Urban Barry Belt in Quebec’s Abitibi region and the
commissioning of a new exploration program focused on the southern portion of Mosseau and the
100% owned Labelle property.
DRILLING UPDATE
Harvest Gold has completed three (3) additional holes totalling 654 metres in the central part of
the Mosseau property, bringing the total completed to date to 14 drill holes for 3,030 metres.
The recently completed holes targeted the central portion of the property, where historical
prospecting and diamond drilling work suggested strong potential and continuity of the gold
mineralization (See Figure 1). Samples are being sent to the laboratory as each hole is logged, and
assay results from the initial holes are expected within the next few weeks.
In addition, t he Company has temporarily paused its ongoing diamond drill program at the
Mosseau Property in recognition of the local First Nations Cultural Week, the National Day of
Truth and Reconciliation and the annual fall hunting season.
Rick Mark, President and CEO of Harvest Gold, state s: “Harvest Gold is dedicated to advancing
the Mosseau Project in a manner that is respectful of Indigenous traditions and community
activities. Temporarily halting our drill program at this time reflects our commitment to working
collaboratively with our partners and shareholders.”
The Mosseau Property straddles the Eeyou Istchee –James Bay and Abitibi territories, as well as
two hunting zones in Quebec (Zones 13 and 16). With hunting season in this area extending from
September 27 to October 26, Harvest Gold plans to resume drilling in the central part of the
Mosseau Property following the annual fall hunting season.
Harvest Gold is committed to building and maintaining positive, transparent, and mutually
beneficial relationships with local Indigenous communities. The Company believes that advancing
exploration activities with respect and understanding is fundamental t o responsible resource
development.
FALL 2025 EXPLORATION PROGRAM
Harvest Gold has engaged IOS Geosciences of Chicoutimi , Quebec to operate its fall field

the Mosseau and LaBelle properties (see Figures 2 and 3). This work is designed to build on recent
high-resolution magnetic survey results and to further refine drill targets for upcoming exploration
campaigns.
The soil sampling program, to begin on October 27 , after hunting season, will include the
collection of over 1,000 samples. Sampling lines will be spaced at 200 metres, oriented
perpendicular to the known ice-flow direction and be taken at 25-metre intervals along each line.
The Company will also be undertaking a prospecting and mapping program in areas of the property
that have seen little to no previous field work. This work is designed to broaden the geological
understanding of underexplored areas and to help refine future exploration targeting.

SAMPLING, QAQC, AND LABORATORY ANALYSIS SUMMARY
All core logging and sampling completed by Harvest Gold as part of its diamond drilling program is subject
to a strict standard for Quality Control and Quality Assurance (QAQC), which includes the insertion of
certified reference materials (standards), blank materials, and field duplicate analysis. NQ-diameter sawed
half-core samples from the drilling program at Mossseau were securely sent by Company geologists to
AGAT Laboratories Ltd. (AGAT), with sample preparation in Val -d’Or, Québec and analysis in Thunder
Bay, Ontario, where samples were processed for gol d analysis by 50 -gram fire assay with an atomic
absorption finish. Samples from selected holes were securely sent to AGAT in Calgary, Alberta, for multi-
5
element analysis (including silver) by inductively coupled plasma (ICP) method with a four-acid digestion.
AGAT sample preparation and laboratory analysis procedures conform to requirements of ISO/IEC
Standard 17025 guidelines and meet the requirements und er NI 43-101 and CIM best practice guidelines.
AGAT is independent of LaFleur Minerals.
