HARVEST GOLD PROVIDES COMPREHENSIVE UPDATE: ROSEBUD PROJECT (NEVADA), MOSSEAU AGREEMENT WITH VIOR, AND EIGHT-MONTH PROGRESS REPORT ON URBAN BARRY BELT PROPERTIES (QUEBEC)

Harvest Gold Corp. has provided an update to shareholders on its long-held $1-million Rosebud project assignment agreement and on its agreement with Vior Inc. to acquire the Mosseau property, and has summarized the growth and development of its large prospective gold/base metal property package in the Abitibi region in Northern Quebec.

Harvest Gold's three-property land position now totals 401 mineral claims covering 21,372.81 hectares and over 50 kilometres of strike length of favourable and potentially mineralized structures, strategically located within the highly prospective Urban Barry greenstone belt.

Harvest Gold president and chief executive officer Rick Mark states: "Today, we are providing our shareholders an update on a few items, including our $1-million assignment agreement on the Rosebud project in Nevada recently acquired by newly TSX-listed Blossom Gold (BGAU). They are aggressively preparing Rosebud for possible production in 2027 with their 14,382-metre drill program, now under way. I also thought it important to make clear that we are very close to increasing our ownership position to 80 per cent of Mosseau. With an additional $1.3-million in work this summer, we will have passed that work commitment threshold. Finally, a summary of late 2025, including the last five holes at Mosseau and our connecting LaBelle and Mosseau."

Rosebud/Blossom Gold

In 2015, Harvest Gold sold its Nevada Rosebud project. It carried an assignment agreement that includes " ... the sum of $1-million payable to Harvest Gold within 30 days of the closing of a debt or equity financing, the proceeds of which are to be used primarily to fund the construction and commissioning of a mine on the property."

Blossom Gold Inc., listed on the Toronto Stock Exchange on Jan. 29, 2026, under the symbol BGAU. The company's primary asset is the Rosebud project in Nevada which included the assignment agreement.

Blossom is already very active at Rosebud as evidenced by its chief executive officer's comment in their April 6, 2026, press release that reads, in part " ... we will be well prepared to deliver on our planned 80,000 feet (24,384 m) core drilling program, and open and rehabilitate the underground later this year to complete infill and expansion drilling for our open pit resource."

Four rigs are expected to be in operation by mid-April with the entire drilling program expected to be completed by the end of Q2 2026.

The Rosebud project is a former gold producer that was operated from 1997 to 2000 by a Newmont-Hecla joint venture.

The Vior agreement on Mosseau: spend $1.3-million before Dec. 31, 2027, to control 80 per cent

Harvest is quickly moving towards an 80-per-cent/20-per-cent joint venture with Vior on Mosseau. The key element, the work commitment component of the agreement, requires Harvest Gold to spend a minimum of $1.3-million on Mosseau before Dec. 31, 2027.

The company intends to meet that threshold in the summer of 2026. Harvest Gold has identified 20 priority drill targets for its 2026 program at Mosseau. At least eight of these targets lie within 500 metres of the high-grade discovery hole (105 grams per tonne Au over 1.15 m), highlighting strong near-discovery expansion potential.

Mosseau/Labelle accomplishments

The 2025 exploration programs significantly advanced Harvest Gold's Urban-Barry portfolio, highlighted by the discovery and expansion of a large-scale gold system within the combined Mosseau-LaBelle projects. Integrated work, including drilling, airborne magnetics, soil geochemistry, prospecting and geological mapping, successfully defined 50 high-priority targets along the Kiask River mineralized corridor (KRMC) and in the general area.

At Mosseau, drilling confirmed strong gold mineralization in both the northern and central parts of the property. The company spent approximately $3-million on exploration in the second half of 2025 with the majority on a 21-hole, 4,692-metre drill program. The program returned several significant gold intersections, one of the most notable in the central part of the property, within the KMRC, included a high-grade intercept of 105.0 g/t Au over 1.15 metres. Additional broader intercepts along strike confirmed a mineralized corridor up to 21 metres wide extending for approximately three kilometres, which remains open in all directions. In the northern part of the property, the best intersection included 8.67 g/t Au (gold), 203 g/t Ag (silver), 2.26 per cent Cu (copper), 0.16 per cent Zn (zinc) and 0.05 per cent Pb (lead) over 0.6 metre associated with semi-massive sulphides within a broader zone of 1.90 g/t gold over 5.4 metres.

2025 drill program: final five holes

Harvest Gold would also like to report the results from the final five holes completed in its 2025 drill program (Table 1). The drill holes targeted gold in soil anomalies associated with magnetic highs to the north of the Kiask River deformation zone, in the central part of the Mosseau property. The most significant results from these five drill holes included anomalous copper intersections of 464 parts per million Cu over 3.0 m (SW-25-29) and 802 ppm Cu over 0.9 m (SW-25-34). These anomalous Cu intersections are considered significant in that it reinforces copper as a key pathfinder for gold mineralization on the Mosseau property. Both these intersections are from a northern, previously untested horizon parallel to the Kiask River deformation zone and proximal to an untested gold in soil anomaly. This horizon is interpreted to represent a possible extension of the Morono deposit horizon, based on its proximity to the Wilson intrusion.

Connecting LaBelle to Mosseau

A high-resolution airborne magnetic survey was remarkably instructive as it showed that the KRMC extends far beyond the current drill area. The KRMC can now be traced for approximately 32 kilometres along strike and continues directly onto the LaBelle property. Exploration at LaBelle, including magnetic surveys, soil geochemistry, prospecting and mapping, confirming this southeastern extension and identified several priority follow-up drill targets, highlighting strong district-scale discovery potential.

The company then acquired 24 additional mineral claims (1,356 hectares) from two prospector groups, effectively linking the Mosseau and LaBelle properties. These new claims, also within the Kiask River mineralized corridor, now provide Harvest control over approximately 32 continuous kilometres of prospective strike length.

Urban Barry accomplishments

In the fall of 2025, a regional till sampling program was conducted by IOS on behalf of Harvest Gold. A total of 137 till samples were collected using hand shovel that yielded a total of 1,175 gold grains. The average normalized gold grain count per sample is 10.52 grains, with a maximum of up to 27 gold grains.

Eight samples are considered anomalous in term of gold grain count. These samples are focused in an area in the northwestern part of the property, stretching about 2.5 km long by 1.3 km wide, a dispersal train largely composed by modified grains and is outline along the main last glacial ice-direction to the southwestern. This area contained 30 per cent of the pristine gold grain identified on the Urban Barry project. Three sample from that same dispersal train, located at most up-ice line, have anomalous and enriched content in nickel and chromium in the fine fraction of till, suggesting an association with ultramafic rocks. Other cluster of till samples enriched in Co, Ni, Ag and Zn were also identified.

The results of the till survey be integrated with the existing data sets and a field reconnaissance and geological mapping survey of the outcrops in the vicinity of the identified dispersal train will be undertaken to prioritize future drilling.

The company also announces that, further to its news release dated March 12, 2026, it has issued an aggregate of 375,000 common shares at a deemed price of 6.5 cents per share. The issuance of the shares represents the first payment required pursuant to the definitive agreement for the purchase of the Audet-Robert claim blocks located in the Urban Barry greenstone belt of Quebec. The shares are subject to a four-month hold period pursuant to securities laws in Canada, expiring on July 25, 2026.
