HARVEST GOLD EXPANDS THE MINERALIZATION CORRIDOR ALONG THE KIASK RIVER FAULT AT ITS MOSSEAU PROJECT IN QUEBEC

Harvest Gold Corp. has released the results of its fall 2024 prospecting and geological mapping program carried out at its Mosseau property. The Mosseau project covers 21 kilometres of favourable strike in the Urban-Barry greenstone belt region.

A field program consisting of prospecting, geological mapping and soil sampling was carried in the central part of the Mosseau property in October and November, 2024.

Rick Mark, chief executive officer of Harvest Gold, stated: "The central part of the Mosseau project has seen significantly less historical exploration than the northern part of the property. We had a limited budget for groundwork at Mosseau in 2024 and chose to focus on this area and its through-going structure, the Kiask River fault. We have confirmed the existing surface gold showing and the discovery of new mineralization along strike significantly increases the potential scale of this system and will guide us in selecting drill targets for an expected summer drill program."

The summer 2024 work confirmed and expanded the historical gold mineralization along the Kiask River mineralized corridor, which included 2.93 grams per tonne gold over 5.0 metres from a drill hole completed by Vior in 2017 and grab samples up to 12.9 grams per tonne gold located one kilometre to the southeast along strike. The Harvest field program extended the mineralized zone 600 metres to the southeast with grab samples of 3.27 grams per tonne gold and 2.51 grams per tonne gold. The mineralized corridor was also extended 1,100 metres along strike to the northwest with 0.24 gram per tonne gold in a grab sample. This fieldwork has confirmed a minimum mineralized strike length of 3.0 kilometres.

Grab samples are selective by nature and may not be representative of the overall mineralization on the property. While they are useful for identifying areas of interest and guiding further exploration, they should not be relied upon as an indicator of the average grade or extent of mineralization.

This three-kilometre mineralized strike strongly correlates with a regional linear magnetic high, which can be traced for over 10 kilometres (see press release dated May 8, 2024). Much of this area remains underexplored, concealed beneath a thin layer of glacial till. The magnetic signature is associated with sulphide minerals, including pyrrhotite, located within or adjacent to a diorite/gabbro sill that has focused mineralizing fluids along the structure. Several similar, parallel magnetic features have also been identified in the central part of the property, highlighting the area's strong potential and warranting further exploration.

Vior, recognizing the prospectivity of this structure, staked additional claims along strike to the southeast, expanding the company's land position (see press release dated May 6, 2025).

The field program carried out by IOS Services Geoscientifiques included prospecting and geological mapping with the collection of 77 rock samples across key target areas in the central part of the property. The work confirmed the presence of gold-bearing structures consistent with historical results and identified new zones of gold mineralization, extending known mineralized trends and further enhancing the potential of the project.

Results will be available shortly for the regional soil sampling program completed over the central part of the property.

The results of the high-resolution airborne magnetics completed in 2024, along with the prospecting, mapping and soil geochemistry, will serve as the cornerstones for planning of the coming drill program in 2025.

About Harvest Gold Corp.

Harvest Gold is focused on exploring for near-surface gold deposits and copper-gold porphyry deposits in politically stable mining jurisdictions. Harvest Gold's board of directors, management team and technical advisers have collective geological and financing experience exceeding 400 years.

Harvest Gold has three active gold projects focused in the Urban Barry area, totalling 377 claims covering 20,016.87 hectares, located approximately 45 kilometres to 70 kilometres west of Gold Fields' Windfall deposit.

Harvest Gold acknowledges that the Mosseau gold project straddles the Eeyou Istchee/James Bay and Abitibi territories. Harvest Gold is committed to developing positive and mutually beneficial relationships based on respect and transparency with local indigenous communities.

Harvest Gold's three properties (Mosseau, Urban-Barry and LaBelle) together cover over 50 kilometres of favourable strike along mineralized shear zones.

Quality assurance/quality control statement

All rock samples collected during the program were securely transported to Activation Laboratories (Actlabs) in Ancaster, Ont., an independent and ISO/IEC 17025-accredited laboratory. Sample preparation included crushing, splitting and pulverizing to 95 per cent passing 105 microns. Gold analysis was performed using fire assay with an inductively coupled plasma mass spectrometry (1A2-ICPMS) finish. A multielement analysis (63 elements) was also done on the samples using an aqua regia digestion/ICP-MS (Ultratrace-1). Borate fusion with XRF (X-ray fluorescence) finishing was carried out for samples exceeding the limit for tungsten. The company follows industry-standard QA/QC protocols, including the insertion of certified reference materials, blanks and duplicates to ensure the accuracy and precision of the results.
