Harvest Gold Discovers New Mineralized Horizon At The Trench 1B Target: Provides Results From The First Six Holes Of Its Mosseau Drill Program (TheNewswire) Vancouver, British Columbia / November 25, 2025 ‑ TheNewswire - Harvest Gold Corporation (TSXV: HVG) (“ Harvest Gold ” or the “ Company ”) is pleased to announce the first series of assay results from its maiden drill program at its Mosseau property in the Urban Barry Belt in Quebec’s Abitibi region. Rick Mark, President and CEO of Harvest Gold, states: “The discovery of a parallel 600m strike length horizon 100m to the east of the known lens at the Trench 1B target confirms that our drill plan to expand previously identified historical showings in the Northern Area is working. I would also note that our geology team is very encouraged with the style of the semi-massive mineralization that includes both precious and base metal mineralization. These first results represent approximately 20% of our 2025 drill program.” Drill Program Highlights: First 6 Holes Discovery of mineralized horizon approximately 100 m east of Trench #1B in the northern part of the Mosseau property. Mineralization is open and associated with a moderate Induced Polarization (IP) anomaly with a 600 m strike length. Highlights from the drill program include 1.90 g/t Au over 5.4 m, including 8.67 g/t Au over 0.6 m and 1.10 g/t Au over 6.0 m, including 2.02 g/t Au over 1.5 m. Higher-grade gold mineralization is associated with the presence of semi-massive sulphides with elevated key pathfinder elements such as Ag, Cu, Zn and Pb Drilling Program Summary and Significant Assay Results Fourteen (14) drill holes have now been completed, totalling 3,030 metres, with assay results now published for the first six (6) of these drill holes representing 994 metres, or the first 20% of the planned 5,000 drill program (Figure 1, Figure 2) . Recent drilling in the Northern Area of the Mosseau property near Trench #1B, has returned encouraging results from an area previously known as prospective for gold. The best drill intercept was 1.90 g/t gold over 5.4 metres, including a higher-grade section of 8.67 g/t gold over 0.6 metres in hole MO-25-15. This zone also contains semi-massive sulphides, composed mainly of pyrite and lesser chalcopyrite, with notable silver and base metal values, including 203 g/t silver, 2.26% copper, 0.16 % zinc, and 0.05% lead. The mineralized zone follows a relatively untested horizon, striking NNW-SSE, approximately 100 m east of the Trench #1B, where previous drilling tested it to a vertical depth of less than 50 m. It is interpreted that the semi-massive sulphides, associated with gold mineralization, may also be related to a moderate and relatively untested IP anomaly that can be traced for 600 m along strike. Hole SW-25-14, located 50 m to the SE of hole SW-25-15 described above, intersected widespread gold mineralization that included 1.10 g/t Au over 6.0 m, including 2.02 g/t Au over 1.5 m. Several recent drill holes intersected near-surface gold mineralization, highlighting the strong potential to expand the historical mineralization at the Mosseau Project. These results reinforce our understanding of both the scale and continuity of the gold system . The collar details for the 14 completed drill holes totalling 3,030 metres are shown in Table 1, and the significant assay results and drill hole locations are shown in Table 2. True widths of the mineralized zones are not known at this time. The Qualified Person (QP) is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the assay data disclosed in this news release . Diamond drilling is ongoing in the Central Area of the Mosseau property, where the Company had identified several coincidental soil geochem anomalies associated with airborne magnetic features (July 24, 2025). 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 5). 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.
