UPDATE ON THE MOSSEAU DRILL PROGRAM AND DETAILS OF NEW FALL, 2025 EXPLORATION PROGRAM

Harvest Gold Corp. has provided an 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-per-cent-owned Labelle property.

Drilling update

Harvest Gold has completed three 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. 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, the company has temporarily paused its continuing 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 chief executive officer of Harvest Gold, states: "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 Sept. 27 to Oct. 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 to responsible resource development.

Fall 2025 exploration program

Harvest Gold has engaged IOS Geosciences of Chicoutimi, Que., to operate its fall field exploration program, which will include soil sampling, prospecting and mapping across parts of the Mosseau and LaBelle properties. 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 Oct. 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 fieldwork. This work is designed to broaden the geological understanding of underexplored areas and to help refine future exploration targeting.

Sampling, QA/QC (quality assurance/quality control) 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, 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, Que., and analysis in Thunder Bay, Ont., where samples were processed for gold analysis by 50-gram fire assay with an atomic absorption finish. Samples from selected holes were securely sent to AGAT in Calgary, Alta., for multielement 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 under National Instrument 43-101 and CIM (Canadian Institute of Mining) best practice guidelines. AGAT is independent of LaFleur Minerals.
