2026 MOSSEAU DISCOVERY DRILL PLAN: PURSUE THE DISCOVERY HOLE

Harvest Gold Corp.'s geological team has been able to define 50 drill targets along the 32-kilometre length of the Kiask River mineralized corridor within its 100-per-cent-controlled, combined Mosseau/LaBelle property in the Urban Barry belt, Quebec. Harvest Gold has prioritized 20 targets for its planned 2026 drill program in the central part of the Mosseau property.

Eleven of those 20 priority targets are along a two-kilometre stretch of a critical magnetic high feature. At least eight of those holes will be within 500 metres of the Discovery hole, which assayed 105 grams over 1.15 metres (MO-25-05) as announced on Feb. 11, 2026, of this year.

Rick Mark, president and chief executive officer of Harvest Gold, stated: "Last year, in our maiden drill program, we drilled 21 exploratory holes over approximately nine kilometres of the Mosseau property. Since then, we have acquired 24 claims and now fully control the Mosseau/LaBelle property, which includes the entirety of the 32-kilometre-long Kiask River mineralized corridor. This year, after analyzing 2025 drill results, revisiting historical databases, and adding new geochemistry and prospecting results, we have 50 defined drill targets along the 32 kilometres, but will focus on 20 holes emanating from our 2025 Discovery hole."

The most significant exploration results of the program were obtained in the central area along the KMRC, which had seen very limited historical exploration. Drilling in this area confirmed the presence of a continuous gold-bearing corridor and returned high-grade mineralization, including an intersection of 105.0 grams per tonne gold over 1.15 metres, which included visible gold, 4.3 g/t silver and 464 parts per million copper, occurring between 120.9 m and 122.5 m down the hole in DDH 25-25.

This interval occurs within a broader halo of lower-grade mineralization and is supported by several additional intercepts along strike that demonstrate both continuity and scale, including 0.50 g/t Au over 16.35 metres (MO-25-026), 0.76 g/t Au over 5.85 metres (MO-25-027) and 0.22 g/t Au over 16.0 metres (MO-25-028). Collectively, the drilling defines a mineralized corridor up to 16 metres wide, traced over approximately three kilometres and tested only to shallow depths of roughly 100 metres. The system remains open in all directions and represents a compelling exploration target for future work.

Sampling, quality assurance/quality control and laboratory analysis summary

All core logging and sampling completed by Harvest Gold as part of its diamond drilling program or prospecting program are 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 Mosseau were securely sent by company geologists to Agat Laboratories Ltd., 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 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 Canadian Institute of Mining, Metallurgy and Petroleum best practice guidelines. Agat is independent of Harvest Gold.

Grab samples reported in this news release were collected by company personnel in accordance with industry standard practices. Grab samples are selective by nature and may not be representative of the underlying mineralization.

The historical drilling results disclosed herein were completed by previous operators and have not been independently verified by the company. While the company considers these historical results to be relevant and reliable for exploration purposes, readers are cautioned that a qualified person has not completed sufficient work to verify the data. Accordingly, the company is treating these results as historical in nature. Verification of historical data, including confirmation drilling, may be required before the information can be relied upon for economic or resource estimation purposes.
