On December 18, 2023 Harvest Gold Corporation announced that it had entered into an Option Agreement (the “Agreement”) with Vior Inc. (“Vior”) (TSXV: VSR). Pursuant to the Agreement, Harvest Gold can earn up to a 100% interest in the Mosseau Gold Project (“Mosseau” or the “Mosseau Gold Project”), subject to TSX Venture Exchange (the “TSXV”) approval.
Mosseau spans 193 claims totaling 9,735.56 hectares (97.36 km2), which includes a 21 km long gold-bearing structure running through the length of the property. Mosseau adjoins the Urban Barry Greenstone Belt of the Abitibi Region of Quebec (Figure 1). Vior is a Montreal based, Quebec-focused mineral exploration company and is owned 14.1% by Gold Fields Inc. (“Gold Fields”).
Rick Mark, President and CEO of Harvest Gold stated: “I am very pleased to inform our shareholders that our year-long search for a new, high-quality gold exploration project in a mining-friendly jurisdiction is complete and, further, we can earn 100% of this opportunity. Mosseau has only recently been consolidated by Vior, so it has not undergone any extensive, systematic exploration in over 35 years, enhancing our chances for discovery.”

The Mosseau Gold Project
Mosseau lies at the western boundary of the prolific Urban Barry Greenstone Belt, an area renowned for both historic and current mining activities, including the Windfall deposit. Notably, Osisko Mining (recently merged with Gold Fields Inc.) and the well-known prospector, Shawn Ryan, hold neighboring claims (Figure 2). Recent wildfires and logging activities have fortuitously improved access to the property and revealed numerous new outcrop exposures, which further enhance exploration prospects.
Mosseau has been amalgamated under single ownership for the first time by Vior. It is 100% owned by Vior, with the majority of the claims not subject to any underlying royalties or encumbrances.
Mark Fedosiewich, Director and Chairman of Vior commented: “Vior is pleased to announce the execution of this definitive Agreement with the experienced and proven team at Harvest Gold. Our recently consolidated district-scale Mosseau Gold Project warrants the resources and commitment that Harvest Gold will dedicate to unearth a significant new discovery at Mosseau.”

The Property
Warren Bates, Director of Property Investigation for Harvest Gold states: “We believe that with the distinct geological characteristics defined below, and on a more local property scale, the presence of ultramafic rocks plus Cu-Ni mineralization, we are looking at an area representing deep seated structures. This ground has also undergone significant uplift and movement as indicated by an interpreted sedimentary basin, all features that are common to many of the more important gold camps.”
The Mosseau Gold Project exhibits several geological characteristics common to significant orogenic gold deposits, including:
- Major Greenstone Belt within the Abitibi region with significant known gold deposits (Urban-Barry)
- Regional large scale deformation zone (Toussaint and Kiask River fault zones)
- Geological framework including variable intrusives (felsic to ultramafics), bi-modal volcanism and sedimentary basins
- Demonstrated continuity of property scale mineralized zones (Morono Shear Zone)
- Favourable gold environment with the presence of polymetallic mineral showings (Au, Cu, Ni)
Mosseau hosts numerous gold showings and prospects, as well as copper and nickel occurrences (Sigeom), both explored and underexplored.
Field investigations and drill core review by Harvest Gold have verified the presence of shear-hosted gold mineralization. The property contains multiple, parallel shear zones consisting of quartz-sericite schist, which further underscores its potential for gold discovery.
Exploration work on the Mosseau Project
On February 28, 2024, the Company announced that Novatem, Inc, a Quebec based company specializing in the performance of high-resolution airborne geophysical surveys, had been selected to perform an airborne magnetic of survey over the Mosseau Project.
On April 18, 2024 the Company announced that it had completed a 1,646 line-km high-resolution helicopter survey, covering 53.6 km2 over the Mosseau Project.
The helicopter-borne system included two laser optically pumped magnetic sensors providing 1,000 measurements per second (1,000 Hz) from a “stinger” mounted at the front of a Guimbal G2 light helicopter. The survey was completed with 50 m lines and 500 m control lines spacing and at a minimum survey drape elevation of 15 m above the ground (Figure 3).
Figure 3: Magnetic coverage of Mosseau Project overlaid with the gold showings
A comparison of the Company’s magnetics map with the Quebec government regional magnetics map flown between 1970-1990 using the technology of the day shows much greater resolution in the current survey (Figure 4).
Airborne Magnetic Survey Highlights
- Enhanced Aeromagnetic Resolution: The survey was completed with 50 m line spacing and at a minimum survey drape elevation of 15 m above the ground. The advantage of a single continuous survey is that it does not require the merging of various digital datasets of different scales and resolutions. (Government regional survey included flight lines at 200 m spacing and survey height of 120 m).
- Increased Geological Understanding: The survey provides a much better definition of the important mineralized contact between volcanic and intrusive rocks, different magnetic domains, along with folding on the property.
- Mineralized Structures: The combination of the Mag survey and known gold showings provides better definition and continuity of mineralized horizons when known mineral showings are incorporated. The survey also aids in the identification of significant NE cross cutting features potentially controlling mineralization.

On April 29, 2024 the Company announced that it had made significant progress in completing compilation work on Mosseau which included incorporating the recent high-resolution helicopter-borne magnetic survey data with the LiDAR data (Figure 5) and the Digital Elevation Model (Figure 6). Other data the Company is analyzing in the structural study includes field geological measurements along with topographic data. The compilation of the various datasets allows the Company to trace key shear zones and important cross cutting fault zones across the property (Figure 7). These shear zones and faults are important for focusing gold mineralization within an environment best known for its shear hosted gold deposits.

Figure 7: Interpreted Structural Features - Mosseau Project
On May 8, 2024 the Company announced completion of the compilation work that included updating the geology map and identifying key mineralized stratigraphic contacts and structures meshed with historic diamond drilling data from 1949 to present and surface samples to help define lateral extensions of the interpreted mineral horizons, which will provide important information in formulating drilling strategies at Mosseau.
Three important styles of mineralization have been identified on the property in relation to the magnetic patterns observed.
Large dilation zones have been identified by the recognition of a change in magnetic domains (Figure 8). Within these dilation zones, several secondary structural features are interpreted, including the historical Morono deposit that has been traced for 1 km along strike.
Intersecting NE and NW trending magnetic featuresin the central part of the property were observed that corresponded to shear zones identified in the field. Figure 10 illustrates the strong correlation between the known gold mineralization and the magnetic high features. Numerous other targeted shear zones are also identified by similar, parallel magnetic features.
Liner NW-SW trending magnetic high features features in the central part of the property were observed that corresponded to shear zones identified in the field. Figure 10 illustrates the strong correlation between the known gold mineralization and the magnetic high features. Numerous other targeted shear zones are also identified by similar, parallel magnetic features.

A field program consisting of prospecting, geological mapping and soil sampling was carried in the central part of the Mosseau property in October and November 2024 (see Figure 11).
Figure 11: Mapping and Prospecting (2024) – Central Area
The 2024 field work was focused in the central part of the Mosseau property and confirmed and expanded the historical gold mineralization along the Kiask River Mineralized Corridor, which included 2.93 g/t Au over 5.0 m from a drill hole completed by Vior in 2017 and grab samples up to 12.9 g/t Au located 1 km to the southeast along strike. The 2024 Harvest field program extended the mineralized zone 600 m to the southeast with grab samples of 3.27 g/t Au and 2.51 g/t Au. The mineralized corridor was also extended 1,100 metres along strike to the northwest with 0.24 g/t Au in a grab sample (Figure 12). This field work has confirmed a minimum mineralized strike length of 3.0 km.
Figure 12: Mapping and Prospecting Results (2024) – Central Area
This 3 km mineralized strike strongly correlates with the regional linear magnetic high that can be traced for over 10 kilometres (Figure 13). Much of this area remains underexplored, concealed beneath a thin layer of glacial till. The magnetic signature is associated with sulphide minerals, including pyrrhotite, located within or adjacent to a diorite/gabbro sill that has focused mineralizing fluids along the structure. Several similar, parallel magnetic features have also been identified in the central part of the property, highlighting the area’s strong potential and warranting further exploration.
Figure 13: Gold Showings Associated with magnetic highs – Central Area
The soil sampling program was carried out by IOS Services Geoscientifiques in October and November 2024 and included the collection of 605 soil samples covering favourable geology and a distinctive magnetic domain in the central part of the property (Figures 14).
Figure 14: Soil Samples collected within the Central Area
Results from the soil geochemical program highlight distinctive gold targets; the greater than 98th percentile Au Z-Score values define eight zones in and parallel to the Kiask River Mineralized Corridor (KRMC) (Figure 14). Three of the gold trains are immediately to the south and down-ice of the KRMC, confirming known mineralization from previous drilling and prospecting results. Another five (5) gold trains are parallel to the KRMC, to the North and the South of the KRMC. These targets are also associated with magnetic highs and geologically by diorite and gabbro’s in the local stratigraphy (Figure 15, Figure 15). The soil sampling program included lines at a 200 m spacing, perpendicular to the known ice flow direction, and sample stations at every 25 m. The significance of the anomalies is not only determined by the gold grade and Z-score, but also by the contiguity of the anomalous samples.

The compilation work, in conjunction with the results of the 2024 high-resolution magnetic survey, field program that included prospecting and geological mapping that was carried out in the central part of the Mosseau property have defined upcoming drill targets to the north and along the Kiask River Mineralized Corridor, as well as identified new targets in the central part of the Mosseau property.
The planned 5,000 metre diamond drill program will focus on testing near-surface gold targets in two key areas of the property, namely the northern and central parts of the property (Figure 17, Figure 18, Figure 4). Both of these areas host similar geological, geophysical and structural features:
The more known northern area hosts numerous gold showings that remain open along strike and at depth.
The central area, and particularly the Kiask River Mineralized Corridor, has seen very limited historical exploration and was the focus of Harvest’s 2024 field work.
The drill targets have been developed through a detailed review and integration of:
- Historical showings
- Previous exploration work, including Induced Polarization and geological mapping surveys
- High-resolution airborne magnetic surveys
- Prospecting and reconnaissance mapping
- Soil sampling program
These exploration efforts have highlighted fifteen high-priority targets that can host significant gold mineralization. The planned drill program will also be the first systematic testing of the central area of Mosseau and is the beginning of unlocking the mineral potential of the Mosseau Project.
