Harvest Gold Expands Flagship Mosseau Property In Quebec With The Acquisition Of 42 Additional Mineral Claims

VANCOUVER, British Columbia / May 5, 2026 – TheNewswire – Harvest Gold Corporation (TSXV: HVG) (“Harvest Gold” or the “Company”) is pleased to announce that it has expanded its Mosseau Property through the acquisition of an additional 42 mineral claims (2,367.2 ha). The Mosseau–Labelle-Urban Barry land package now comprises 443 mineral claims covering approximately 23,740 ha.

Harvest Gold President and CEO, Rick Mark, commented: “We are continuing to build our 100% controlled land package in the very prospective Urban Barry Belt in Quebec. These new claims are strategically located and host favorable geology and structural features similar to those at our flagship Mosseau Project. They are adjacent to the southwestern boundary of Mosseau.”

The newly staked claims cover prospective volcanic stratigraphy of the Quévillon Group, including basalts and andesites with intermediate to felsic tuff horizons and gabbro sills. These rock types are analogous to those hosting the Kiask River Mineralized Corridor (“KRMC”) located immediately to the north (Figure 1).

Geological interpretation indicates that these volcanic units bifurcate southward, forming a southern extension of the same stratigraphic package that hosts the KRMC. The sequence may be folded around, or intruded by, the Cuvillier Pluton, which is interpreted to be synvolcanic or syntectonic in age.

The new claims are situated directly south of the KRMC and remain largely underexplored, with historical work limited primarily to regional airborne magnetic and electromagnetic surveys as documented in SIGÉOM.

Notably, the property exhibits similar linear magnetic signatures and interpreted intermediate to mafic sills to those associated with mineralization along the KRMC (Figure 2). Preliminary interpretation of magnetic and LiDAR datasets has identified several structural features, including north-south, northeast-southwest, and northwest-southeast orientations, which may represent key controls on mineralization.

Geological mapping was conducted by Québec’s Ministry of Natural Resources and Forests (MERN) in 2014 over the Lac Cuvillier area (NTS 32C15), which provides a solid geological framework for ongoing exploration. In addition, the property has seen improved access in recent years through an expanding network of logging roads.

Harvest Gold plans to initiate prospecting and evaluate the economic potential by the use of regional soil geochemistry surveys across the newly acquired ground during the upcoming field seasons.

This strategic acquisition further strengthens Harvest Gold’s land position in the Urban-Barry region, bringing its total holdings to 443 claims covering 23,740 hectares across three projects. The new claims secure mineral rights over an underexplored portion of the volcanic belt, as supported by Québec government magnetic surveys and geological mapping.

The claims were acquired through low-cost staking and significantly expanded the Company’s exploration footprint by over 10% over highly prospective geology.
