Harvest GOLD Discovers Significant GOLD-Silver-Copper Halos in the Northern Part of the Mosseau Property

Exploration Programs

HARVEST GOLD DISCOVERS SIGNIFICANT GOLD-SILVER-COPPER HALOS IN THE

NORTHERN PART OF THE MOSSEAU PROPERTY

Vancouver, British Columbia / January 29, 2026 - Harvest Gold Corporation (TSXV: HVG)

(“Harvest Gold” or the “ Company”) is pleased to announce the results of a detailed review of

current and historical drilling data conducted in light of the Company’s 2025 drilling program .

This work has identified several significant near-surface Au-Ag-Cu halos in the northern portion

of the Mosseau Property, its flagship property in the Urban Barry Belt in Quebec’s Abitibi region.

Rick Mark, President and CEO of Harvest Gold, stated: “Our most recent press release announced,

among other things, 10 and 19 -meter widths of anomalous gold or copper at depth below the

historic, non 43 -101 Morono gold deposit. We realized we had identified something new, forty

plus years after the last Morono drill program. We also realized samples were not analysed for

copper and silver during historic drilling. That led our Geological team to evaluate the historical

data of the entire North area of Mosse au. This new understanding of the area’s mineralization

changed our thinking.”

Louis Martin, geologist for Harvest Gold in Quebec states: “The iden tification of broad, near -

surface gold with Ag -Cu pathfinders from historical drilling significantly strengthens the

interpretation of our 2025 drill results. Re-evaluating the Mosseau data using this model continues

to improve our understanding of the mineralizing system and provides a strong technical basis for

targeting and additional drilling in the northern part of the property.”

Following the reporting of wide gold intersections with associated anomalous silver and copper

from the 2025 drill program (see Harvest Gold press releases dated January 8, 2026), the Company

initiated a systematic re -evaluation of historical drill results to identify similar styles of

mineralization. This review applied a lower gold cut-off grade than used by previous operators to

better define broad zones of mineralization consistent with the Au and Ag -Cu pathfinders

recognized in the Harvest Gold 2025 drilling.

As a result of this new analytical perspective, multiple significant Au-Ag-Cu halos have been

identified within several key target areas on the Mosseau Property . Critically, t his allows the

Company to narrow its focus to three principal areas of interest, including Trench #1, the Morono

Gold Deposit, and what were thought to be isolated targets along the northern boundary of the

property (see Figure 1, Figure 2).

Examples of broad Au-Ag-Cu halos from holes drilled by SOQUEM in 2001 ( GM59164) in the

area of Trench #1 include:

• 1.44 g/t Au over 26.2 metres (hole 1217-01-13)

• 3.37 g/t Au over 14.1 metres (hole 1217-01-14)

Both drill holes also returned anomalous silver and copper values directly associated with the

higher-grade gold intervals , similar to the results observed in the 2025 drilling by Harvest Gold

(see Table 1).

At the Morono Gold Deposit, several wide historical intersections—locally extending up to 35.36

metres—further illustrate the potential for extensive gold halo development. Selected historical

intersections include:

• 3.84 g/t Au over 8.4 metres (M-4-88)

• 3.05 g/t Au over 7.62 metres (M-12-87)

• 2.66 g/t Au over 8.35 metres (M-25-87).

Importantly, most of these historical intercepts occur at shallow depths and near surface,

highlighting the potential for bulk-tonnage and open-pit style mineralization, subject to additional

drilling and future economic studies.

Based on these results, Harvest Gold has expand ed its understanding of the Northern area of

Mosseau and believes it now generates an expanded opportunity and is contemplating a follow-up

drill program in the northern portion of the Mosseau Property. The proposed program would

consider up to 40 diamond drill holes totalling up to 6,000 metres to further test and expand these

newly discovered Au-Ag-Cu halo zones.

About Harvest Gold Corporation

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 advisors 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 ha, located approximately 45-70 km west of Gold Fields Limited’s - Windfall

Deposit (Figure 3).

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 km

of favorable strike along mineralized shear zones.
