Harvest Gold Announces Drill Results from Mosseau Property

Vancouver, British Columbia — February 11, 2026 — Leads & Copy —

Harvest Gold Corporation (TSXV: HVG) has announced results from the first five drill holes at its Mosseau Property in Quebec’s Abitibi region. Each hole is within the Kiask River Deformation Zone.

The company intersected 105.0 g/t gold over 1.15 metres in the central part of the Mosseau Property. According to President and CEO Rick Mark, this discovery within the Kiask River Deformation Zone indicates it can host high-grade gold mineralization. The company also noted the presence of an Au-Ag-Cu halo near this high-grade interval.

In 2025, Harvest Gold completed five drill holes along the Kiask River Deformation Zone over a strike length of approximately 3 kilometers. The most significant intersection to date on the Mosseau Property was obtained in hole MO-25-25, which returned 105.0 g/t Au over 1.15 metres, including visible gold, 4.3 g/t Ag and 464 ppm Cu.

This high-grade gold interval is associated with a lower-grade halo of mineralization that returned 0.32 g/t Au over 6.9 metres.

High-resolution airborne magnetics and prospecting work by Harvest Gold have traced the Kiask River Mineralized Corridor for over 10 km along strike across the underexplored central and southern part of the Mosseau property.

Drilling along the Kiask River Deformation Zone by Harvest Gold intersected mineralized shear zones comparable in style and size to gold envelopes with silver and copper pathfinders previously identified in the area of the Morono deposit (see press releases dated January 8, 2026 and January 29, 2026).

Significant intervals from the 2025 drill program in the central part of the property along the Kiask River Deformation Zone include:

0.32 g/t Au over 6.9 m, adjacent to 105.0 g/t Au, 4.3 g/t Ag, 464 ppm Cu over 1.15 m (MO-25-25)

0.50 g/t Au over 16.35 m, including 1.85 g/t Au and 700 ppm Cu over 1.50 m (MO-25-26)

0.76 g/t Au over 5.85 m, including 2.11 g/t Au and 466 ppm Cu over 1.00 m (MO-25-27)

0.22 g/t Au over 16.0 m and 2.48 g/t Au and 571 ppm Cu over 0.50 m (MO-25-28)

0.23 g/t Au over 6.0 m (MO-25-30)

Harvest Gold notes that consistent with the large Au-Ag-Cu halo zones identified in the northern part of the Mosseau Property, higher-grade gold mineralization within these intervals is commonly associated with anomalous silver and/or copper assays.

All drill holes completed along strike by Harvest Gold intersected a gold-bearing corridor that is up to 16 metres wide, traceable for approximately 3 kilometres along strike, and remains shallowly tested to a maximum depth of approximately 100 metres. Additional drilling will further test the Kiask River Mineralized Corridor both along strike and at depth.

The central portion of the Mosseau Property has seen significantly less historical exploration than the northern part of the property. Previous drilling by Vior Inc. in 2017 identified gold mineralization associated with a shear zone along the Kiask River Deformation Zone, returning 1.13 g/t Au over 16.0 metres, including 2.93 g/t Au over 5.0 metres (Source: GM71014).

A high-resolution magnetic survey completed by Harvest Gold outlined a potential second dilation zone, similar in character and larger in scale than the mineralized structures identified in the northern part of the property. Prospecting and mapping by Harvest Gold along these linear magnetic features traced this horizon for approximately 3 km along strike and returned grab samples ranging from 0.24 g/t Au to 3.27 g/t Au (see press release dated May 15, 2025). A soil survey completed in 2025 identified multiple gold-in-soil anomalies, including down-ice from known gold showings associated with the Kiask River Deformation Zone.

The company will release results from the remaining drill holes completed in the central part of the Mosseau Property as assays become available.

Harvest Gold is focused on exploring for near-surface gold deposits and copper-gold porphyry deposits. The company has three active gold projects in the Urban Barry area, totaling 377 claims covering 20,016.87 ha, located approximately 45-70 km west of Gold Fields Limited’s - Windfall Deposit.

Harvest Gold acknowledges that the Mosseau Gold Project straddles the Eeyou Istchee-James Bay and Abitibi territories and is committed to developing positive and mutually beneficial relationships 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.
