Harvest Gold Launches 2026 Drill Campaign At Mosseau

Drill Results Corporate Updates

Vancouver, British Columbia / July 15, 2026 - TheNewswire - Harvest Gold Corporation (TSXV: HVG) (“Harvest Gold” or the “Company”) is pleased to announce that it plans to commence its fully funded 2026 exploration program this weekend with an approximately 4,000-metre diamond drill program at its flagship Mosseau Project

Rick Mark, President and CEO states: “We are now ready to launch our 2026 exploration season starting with a focused drill program designed to build on last year’s high-grade discovery at Mosseau. Our technical team has developed compelling drill targets that have the potential to significantly expand the Kiask River Mineralized Corridor while advancing our understanding of this emerging gold system. This 2026 program positions Harvest Gold for an exciting year of discovery,”

Mark added: “We are equally pleased to be working with Forage Val d’Or and to support their partnership with Mawi of Lac Simon, which reflects our commitment to responsible exploration and meaningful collaboration with Indigenous communities”

The drill program is expected to comprise approximately 20 diamond drill holes targeting the Kiask River Mineralized Corridor (“KRMC”) in the central portion of the Mosseau Project. The KRMC hosts Harvest Gold’s high-grade discovery where drilling intersected 105.0 g/t gold over 1.15 metres (see news release dated February 11, 2026). The upcoming program is designed to expand known mineralization while testing additional high-priority structural and geophysical targets generated through the Company’s recent exploration work.

The Company has awarded the drilling contract to Forage Val d’Or (FVD), one of Quebec’s most experienced and respected drilling contractors. Founded in 1987, FVD operates a diversified fleet that includes hydraulic skid-mounted and helicopter-portable drill rigs and maintains high environmental and operational standards. The company is a member of the Association de l’exploration minière du Québec (AEMQ) and the Canadian Diamond Drilling Association (CDDA) and is currently advancing through the ECOLOGO certification process.

Harvest Gold’s selection of FVD is further strengthened by the contractor’s recently announced partnership with Mawi of Lac Simon, formalized on June 19, 2026. Through this collaboration, Mawi serves as FVD’s exclusive Indigenous partner supporting mineral exploration drilling activities. The partnership reflects Harvest Gold’s commitment to fostering meaningful Indigenous participation and building strong relationships with local communities as exploration advances.

NQ-diameter sawed half-core samples from the drilling program at Mosseau were securely sent by Company geologists to AGAT Laboratories Ltd. (AGAT), with sample preparation in Val-d’Or, Québec and analysis in Thunder Bay, Ontario, 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, Alberta, for multi-element 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 NI 43-101 and CIM best practice guidelines. AGAT is independent of Harvest Gold.
