Harvest Gold Provides Update on its Ongoing Drill Program at Mosseau and Has Completed its High-Resolution Airborne Magnetic Survey of Mosseau and Labelle

(TheNewswire)

Vancouver, British Columbia /September 26, 2025 ‑ TheNewswire - Harvest Gold Corporation HVG
(“Harvest Gold” or the “Company”) ispleased to report on the progress of its ongoing drill program atMosseau, its flagship property in the Urban Barry Belt in Quebec’sAbitibi region.

Rick Mark, CEO of Harvest Gold, commented: “Theconfirmation that the Kiask River Corridor extends southeast into theLaBelle property is an important step forward in our regionalexploration model. Combined with the progress of our ongoing drillprogram, we are steadily advancing our understanding of the goldpotential at Mosseau and LaBelle. We look forward to receiving ourfirst batch of assay results next month and continuing to unlock thevalue of this highly prospective land package.”

DRILLING UPDATE

To date, 11 drill holes have been completed for a totalof 2,191 metres. The completed holes targeted the northern portion ofthe property, where historical prospecting and diamond drilling worksuggested strong potential and continuity of the gold mineralization(See Figure 1). Samples are sent to the lab as the logging of eachhole is completed and assay results from the initial holes areexpected over the next few weeks.

Drilling is now transitioning toward the central partof the property, where additional priority targets have beenidentified based on recent prospecting, geophysics and soilsampling.

AIRBORNE MAGNETIC SURVEY

We have now received the results of the successful high-resolutionmagnetic survey covering the southeastern part of the Mosseau and theadjoining LaBelle properties.

The survey results have identified and confirmed theextension of the magnetic domain hosting the Kiask River Corridor tothe southeast, extending into the LaBelle property. The Kiask RiverCorridor can now be traced for 31 km in a northwest – southeastdirection, with a width up to 2.3 km. This represents a significantdevelopment in the Company’s understanding of the structural andlithological controls on gold mineralization in the area, providingadditional high-priority exploration targets for follow-up. (SeeFigure 2)

Looking ahead, the Company is planning a fallexploration program, which will include soil sampling and prospectingacross parts of the Mosseau and LaBelle properties. These activitiesare designed to build on the recent magnetic survey results andfurther refine drill targets for future exploration campaigns.

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 Swanson 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.
