TheNewswire - Harvest Gold Corporation (TSXV: HVG)(“ Harvest Gold ” or the “ Company ”) is pleased to announcethe latest update on the drill program at Mosseau, its flagshipproperty in the Urban Barry Belt in Quebec’s Abitibi region and thecommissioning of a new exploration program focused on the southernportion of Mosseau and the 100% owned Labelle property.

DRILLING UPDATE

Harvest Gold has completed three (3) additional holestotalling 654 metres in the central part of the Mosseau property,bringing the total completed to date to 14 drill holes for 3,030metres.

The recently completed holes targeted the centralportion of the property, where historical prospecting and diamonddrilling work suggested strong potential and continuity of the goldmineralization (See Figure 1). Samples are being sent to thelaboratory as each hole is logged, and assay results from the initialholes are expected within the next few weeks .

In addition, the Company has temporarily paused its ongoing diamonddrill program at the Mosseau Property in recognition of the localFirst Nations Cultural Week, the National Day of Truth andReconciliation and the annual fall hunting season.

Rick Mark, President and CEO of Harvest Gold, states:“Harvest Gold is dedicated to advancing the Mosseau Project in amanner that is respectful of Indigenous traditions and communityactivities. Temporarily halting our drill program at this timereflects our commitment to working collaboratively with our partnersand shareholders.”

The Mosseau Property straddles the EeyouIstchee–James Bay and Abitibi territories, as well as two huntingzones in Quebec (Zones 13 and 16). With hunting season in this areaextending from September 27 to October 26, Harvest Gold plansto resume drilling in the central part of the Mosseau Propertyfollowing the annual fall hunting season.

Harvest Gold is committed to building and maintainingpositive, transparent, and mutually beneficial relationships withlocal Indigenous communities. The Company believes that advancingexploration activities with respect and understanding is fundamentalto responsible resource development.

FALL 2025 EXPLORATION PROGRAM

Harvest Gold has engaged IOS Geosciences of Chicoutimi,Quebec to operate its fall field exploration program, which willinclude soil sampling, prospecting and mapping across parts of theMosseau and LaBelle properties (see Figures 2 and 3). This work isdesigned to build on recent high-resolution magnetic survey resultsand to further refine drill targets for upcoming explorationcampaigns.

The soil sampling program, to begin on October 27,after hunting season, will include the collection of over 1,000samples. Sampling lines will be spaced at 200 metres, orientedperpendicular to the known ice-flow direction and be taken at 25-metreintervals along each line.

The Company will also be undertaking a prospecting and mapping programin areas of the property that have seen little to no previous fieldwork. This work is designed to broaden the geological understanding ofunderexplored areas and to help refine future exploration targeting.

Sampling, QAQC, and LaboratoryAnalysis Summary

All core logging and sampling completed by Harvest Goldas part of its diamond drilling program is subject to a strictstandard for Quality Control and Quality Assurance (QAQC), whichincludes the insertion of certified reference materials (standards),blank materials, and field duplicate analysis. NQ-diameter sawedhalf-core samples from the drilling program at Mossseau were securelysent by Company geologists to AGAT Laboratories Ltd. (AGAT), withsample preparation in Val-d’Or, Québec and analysis in Thunder Bay,Ontario, where samples were processed for gold analysis by 50-gramfire assay with an atomic absorption finish. Samples from selectedholes were securely sent to AGAT in Calgary, Alberta, formulti-element analysis (including silver) by inductively coupledplasma (ICP) method with a four-acid digestion. AGAT samplepreparation and laboratory analysis procedures conform to requirementsof ISO/IEC Standard 17025 guidelines and meet the requirements underNI 43-101 and CIM best practice guidelines. AGAT is independent ofLaFleur Minerals.
