Goldshore Resources Inc. announced an updated mineral resource estimate (the "MRE") for the Moss deposit ("Moss" or the "Moss Deposit") and East Coldstream deposit ("East Coldstream" or the "East Coldstream Deposit"), both located at its 100%-owned Moss Gold Project in Northwest Ontario, Canada (the "Moss Gold Project" or the "Project"). Upgrading of the MRE to include 23% Indicated Mineral Resources and an increase in the average grade over the 2023 MRE. Indicated Mineral Resource of 1,535 thousand ounces grading 1.23 grams per tonne gold (g/t Au), contained within 38.96 million tonnes.

Inferred Mineral Resource of 5,198 thousand ounces grading 1.11 grams per tonne gold (g/t Au), contained within 146.24 million tonnes. The total resource tonnage increase is just under 1% overall over the 2023 MRE, however the overall grade increase versus the 2023 MRE is approximately 11%. The shears that host gold mineralization have been extensively remodelled as constraining domains, greatly enhancing the reliability of the current MRE.

With gold prices consistent with the 2023 MRE, 94% of the 2024 MRE's tonnes and gold ounces are contained within these shear models. This is a significant increase compared to the 2023 MRE, where only 35% of the tonnes and 65% of the gold ounces were contained in its shear model. The pit depth is constrained by the model (in multiple locations), indicating the potential for a larger pit should the model be extended at depth.

The 2024 Moss Project MRE update is set to be the foundation for resource growth and development towards Tier One status, and leading to a future Preliminary Economic Assessment (PEA). All identified zones within the Project are still open to potential expansion. Technical Overview.

Historical Assay Review. APEX Geoscience Ltd. ("APEX") completed an in-depth review and validation of assays collected before 2010 at the Moss Deposit and East Coldstream Deposit to establish whether the data is suitable for mineral resource estimation. APEX reviewed previous studies' evaluation of twin drilling and resampling programs and drew the following conclusions regarding this data: Five twin holes have been completed in the Moss Zone.

The orientation of these domains is informed by a structural trend model derived from oriented core structural measurements. Additionally, APEX personnel developed an updated geological model to guide estimation domain modelling and facilitate density assignment by geological unit. The shear estimation domains are delineated by connecting intervals of mineralization that align with the structural trend and are predominantly within a single geological unit.

The MRE is based on the combination of geological modelling, geostatistics and conventional block modelling using the Ordinary Kriging method of grade interpolation with locally varying anisotropy variogram models. The Moss Project drillhole database consists of 538 drill holes that intersected the interpreted mineralization wireframes at the Moss Deposit and 156 drill holes that intersected the interpretation mineralization wireframes at the East Coldstream Deposit for a total of 738 Drill Holes used in the Mineral Resource Estimate. Gold assays were composited to 2-meter composite lengths, and the estimation utilized 31,149 composited samples.

A total of 2,812 bulk-density samples are available from the Moss Project drillhole database. This resource classification reflects that much of the drill hole data used for the resource estimate is historical, and no QA/QC data or reports exist for most of these drill holes. The CIM guidelines for mineral resources require that reported mineral resources demonstrate reasonable prospects for eventual economic extraction (RPEEE).

Furthermore, there remains potential for additional parallel shears with gold mineralization in historical drill holes up to 2.5km to the southeast of the Moss Deposit. Resampling of historical drill core will continue, although most core blocks are now illegible rendering resampling impossible. Mr. Michael Dufresne, M.
