Harvest Gold Identifies Significant AU-AG-CU Halo Associated With The Structural / Magnetic Feature On Mosseau (TheNewswire) Vancouver, British Columbia / January 8, 2026 ‑ TheNewswire - Harvest Gold Corporation (TSXV: HVG) (“Harvest Gold” or the “Company”) is pleased to announce the second 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, stated: “As we finish reporting on our 11-hole Northern area program, we are excited to have found new, complex and sizable mineralization in our previously identified ‘dilation zone’, which our geo team interprets to have the types of fluids and traps that can hide deposits. The thick intervals and widespread Au-Ag-Cu mineralization southeast of the Morono deposit, within this structural dilation zone, indicate a regionally extensive and significant gold system. Elevated background values and consistent mineralogical associations support this interpretation. The gold-rich mineralization, accompanied by precious and base metals, shares key similarities with several well-known, gold-rich base metal deposits in the Abitibi.” Drill Program Highlights: Second Batch of Drill Holes Drilling focused on a major structural feature interpreted as a large dilation zone, based on Harvest Gold’s 2024 high-resolution magnetic survey. (see Figure 1) The most southerly hole to date, located 330 m to the SE of the Morono deposit, intersected multiple intervals with anomalous and coincidental Au-Ag-Cu mineralization over the length of the hole (MO-25-24). A hole testing the down-dip extension of the Morono deposit intersected several wide zones of anomalous Au and Cu mineralization over core lengths of 10 to 19 metres (MO-25-22). Highest grade assays from the second batch of 5 drill holes include 2.40 g/t Au over 1.4 m (MO-25-21) and 1.26 g/t Au over 1.5 m (MO-25-20) This brecciated gold-rich base metal mineralization provides new and compelling exploration targets.

Assay results have now been reported for the first eleven (11) holes of the planned drill program (Figure 2). This press release includes the second and final batch of assay results from the northern part of the property. These five holes targeted the structural or dilation zone interpreted from the high-resolution magnetic survey completed by Harvest Gold in 2024 The 5 holes being reported tested the historical Morono S & P Trench target area, the historical, non 43-101 Morono deposit at depth and the SE extension of that Morono deposit where previous prospecting had identified Au-Cu mineralization in boulders. The highest assays from the second batch of drill holes included 2.40 g/t Au over 1.4 m (MO-25-21) and 1.26 g/t Au over 1.5 m (MO-25-20). Both of these intersections were hosted in sheared volcanic rocks with disseminated to small veinlets of sulphides and local quartz veining in the area of Morono S&P showings. Hole MO-25-22 tested the down-dip extension of the Morono deposit at a vertical depth of 325 m. Several substantially wide intersections of anomalous gold or copper were intersected over widths of 10 to 19 m. The most notable intersections included 0.14% Cu over 10.0 m (165.0-175.0m), 0.13 g/t Au over 19.0 m (188.0-199.0m) and 0.12% Cu over 10.0 m (305.0-315.0m). Much of this mineralization contains both shear and brecciated style mineralization (Figure 4). Hole MO-25-24 was the most southeasterly of the holes drilled in the northern part of the property and tested the area over 300 m to the SE of the Morono deposit. This target area was highlighted by previous prospecting work by Vior Inc. that identified Au-Cu rich boulders on surface. Hole MO-25-24 intersected multiple anomalous Au-Ag-Cu intervals over much of the length of the drill hole. The results of this hole highlight a slightly different style of mineralogy than that previously seen on the property, with a good correlation of Au-Ag-Cu assays over multiple intersections throughout the hole. This style of Au-Ag-Cu mineralization is similar to a recent sulphide zone reported from drilling in the northern part of the property, which included 8.67 g/t Au, 203.0 g/t Ag and 2.26% Cu over 0.6 m in hole MO-25-15 (refer to the Company’s press release date November 25, 2025). The host rocks in MO-25-24 are more typically sheared mafic volcanics with sulphides along the fractures and associated with quartz veins. The drill hole indicates excellent potential for a larger deposit and the possibility of expanding the mineralization towards the east within the dilation zone, in an area that remains largely untested.
