Harvest Gold Discovers New Mineralized Horizon At The Trench 1B Target: Provides Results From The First Six Holes Of Its Mosseau Drill Program

(TheNewswire)

Vancouver, British Columbia / November 25, 2025 ? TheNewswire - Harvest GoldCorporation (TSXV: HVG) (“ Harvest Gold ” or the “ Company ”) ispleased to announce the first series of assay results from its maidendrill program at its Mosseau property in the Urban Barry Belt inQuebec’s Abitibi region.

Rick Mark, President and CEO of Harvest Gold, states:“The discovery of a parallel 600m strike length horizon 100m to theeast of the known lens at the Trench 1B target confirms that our drillplan to expand previously identified historical showings in theNorthern Area is working. I would also note that our geology team isvery encouraged with the style of the semi-massive mineralization thatincludes both precious and base metal mineralization. These firstresults represent approximately 20% of our 2025 drill program.”

Drill Program Highlights: First 6 Holes

• Discovery of mineralized horizon approximately 100 m east of Trench#1B in the northern part of the Mosseau property. Mineralization isopen and associated with a moderate Induced Polarization (IP) anomalywith a 600 m strike length.

• Highlights from the drill program include 1.90 g/t Au over 5.4 m,including 8.67 g/t Au over 0.6 m and 1.10 g/t Au over 6.0 m, including2.02 g/t Au over 1.5 m.

• Higher-grade gold mineralization is associated with the presence ofsemi-massive sulphides with elevated key pathfinder elements such asAg, Cu, Zn and Pb

Drilling Program Summary and Significant AssayResults

Fourteen (14) drill holes have now been completed, totalling 3,030 metres, with assayresults now published for the first six (6) of these drill holesrepresenting 994 metres, or the first 20% of the planned 5,000 drillprogram (Figure 1, Figure 2) .

Recent drilling in the Northern Area of the Mosseau property nearTrench #1B, has returned encouraging results from an area previouslyknown as prospective for gold. The best drill intercept was 1.90 g/tgold over 5.4 metres, including a higher-grade section of 8.67 g/tgold over 0.6 metres in hole MO-25-15. This zone also containssemi-massive sulphides, composed mainly of pyrite and lesserchalcopyrite, with notable silver and base metal values, including 203g/t silver, 2.26% copper, 0.16 % zinc, and 0.05% lead. The mineralizedzone follows a relatively untested horizon, striking NNW-SSE,approximately 100 m east of the Trench #1B, where previous drillingtested it to a vertical depth of less than 50 m. It is interpretedthat the semi-massive sulphides, associated with gold mineralization,may also be related to a moderate and relatively untested IP anomalythat can be traced for 600 m along strike.

Hole SW-25-14, located 50 m to the SE of hole SW-25-15 describedabove, intersected widespread gold mineralization that included 1.10g/t Au over 6.0 m, including 2.02 g/t Au over 1.5 m.

Several recent drill holes intersected near-surfacegold mineralization, highlighting the strong potential to expand thehistorical mineralization at the Mosseau Project. These resultsreinforce our understanding of both the scale and continuity of thegold system .

The collar details for the 14 completed drill holestotalling 3,030 metres are shown in Table 1, and the significant assayresults and drill hole locations are shown in Table 2. True widths ofthe mineralized zones are not known at this time. The Qualified Person(QP) is not aware of any drilling, sampling, recovery, or otherfactors that could materially affect the accuracy or reliability ofthe assay data disclosed in this news release .

Diamond drilling is ongoing in the Central Area of the Mosseauproperty, where the Company had identified several coincidental soilgeochem anomalies associated with airborne magnetic features (July 24,2025).

Sampling, QAQC, and Laboratory Analysis 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), whichinclude the insertion of certified reference materials (standards),blank materials, and field duplicate analysis. NQ-diameter sawedhalf-core samples from the drilling program at Mosseau 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 ofHarvest Gold.
