New Gold Discovery Confirmed at Side Well South and Drilling Extends

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 2 and 3).

Rick Mark, CEO of Harvest Gold states: ” This soil geochemical survey, remarkably, the first of its kind on this property, has yielded a breakthrough in our understanding of the gold potential surrounding the Kiask River Mineralized Corridor. These soil geochemistry results, layered upon historic information and Harvest’s recent geophysical, prospecting and mapping results produce target opportunities previously unseen. The geo team is meeting this week to prioritize drill targets.”

Results from the soil geochemical program* highlight distinctive gold targets; the greater than 98 th percentile Au Z-Score** values define eight zones in and parallel to the Kiask River Mineralized Corridor (KRMC) (Figure 4). 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 5, Figure 6).

The soil sampling program, in conjunction with the recently released results of the prospecting and geological mapping was carried in the central part of the Mosseau property The soil sampling program has confirmed existing drill targets along the Kiask River Mineralized Corridor, as well as identified new targets in the central part of the Mosseau property. Previously recognized mineralization in the central part of the property along the Kiask River Mineralization Corridor, identified by Vior in 2017, included 2.93 g/t Au over 5.0 m from drilling and grab samples up to 12.9 g/t Au. The mineralization was confirmed and extended along strike from results of the 2024 prospecting and mapping program (Press release May 15, 2025)

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 .

* Soil sampling surveys are not definitive, and the results are still at an early stage of interpretation, with no guarantee of a mineral discovery

** The anomaly thresholds were determined by IOS using a probabilistic approach. In that the assays results are first transformed into logarithmic data. The Z-score is then calculated for each element of each sample. This significantly limits the range of values and enables the use of a normal distribution for the probability modelling. The anomaly threshold for an element is determined by the difference between the sample’s…
