Star Metro - Rocky Shore Gold Announces Mineral Resource Estimate for the Gold Anchor Project in Central Newfoundland

TORONTO, ON / ACCESS Newswire / April 2, 2026 / Rocky Shore Gold Ltd. ("Rocky Shore" or the "Company") (CSE:RSG) is pleased to announce that the Company has received Mineral Resource Estimates ("MREs") from its Mosquito Hill and Reid Deposits within its Gold Anchor Project, central Newfoundland. The MREs (Table 1) were prepared by Caracle Creek International Consulting Inc. (Sudbury, Ontario) in accordance with the 2014 Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards and Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). The MREs are effective as of March 27, 2026 (the "Effective Date").

Ken Lapierre, President and CEO of Rocky Shore Gold, commented, "The Gold Anchor Project continues to deliver exceptional results and now hosts two cornerstone bulk tonnage open pit gold deposits with expansion potential. We plan to continue to work towards expanding the present MREs this year through the drill bit beginning this summer. With only approximately 15% of the Project systematically explored, Rocky Shore is just beginning to unlock the Project's full potential. A fully funded 2026 program will include airborne geophysics, targeted prospecting and sampling, and diamond drilling focused on new discoveries and resource expansion."

Table 1: Summary of the Two Pit-Constrained Mineral Resource Estimates as of the Effective Date.

Notes to Table 1 (applies to both MREs):

1. Qualified Persons: Scott Jobin-Bevans (P.Geo.) and Curtis Ferron (P.Geo.) of Caracle Creek International Consulting Inc., are the Qualified Persons responsible for this Mineral Resource Estimate as defined by NI 43-101.

2. Resource Classification: The MREs have been classified in the Indicated and Inferred mineral resource categories at the Mosquito Hill Deposit and classified in the Indicated and Inferred categories at the Reid Deposit. Presently, there are no Measured Mineral Resources at the Mosquito Hill and Reid Deposits. Indicated blocks were defined by blocks within the mineralized wireframe satisfying average sample distance

All remaining blocks within the mineralized wireframe were deemed Exploration Potential. Exploration Potential is viewed as a conceptual/geological inventory and is in accordance with the restricted‑disclosure provisions under CIM 2014 standards. The Exploration Potential described herein is not a resource and has not been given gross in‑situ metal values.

3. Reporting Cut-Off Grade: Mineral resources are reported at a cut-off grade of 0.25 g/t Au.

4. High-Grade Capping: Gold assay values were capped at 5.0 g/t Au prior to compositing.

5. Specific Gravity: An average specific gravity (SG) of 2.80 g/cm³ was used for bulk density conversion, based on 39 core measurements from the 2009 and 2010 drilling programs. SG measurements were consistent, ranging from 2.70 to 3.00 g/cm³.

6. Open Pit Optimization: Calculation of the simulated open pit used: a maximum pit slope angle of 50 degrees, US$4,250/oz Au, gold recovery of 85%, gold selling cost of US$425, operating cost of $13.00/t, 2% NSR, 5% dilution, 95% mining recovery, and 10,000 tonnes per day throughput

7. Block Model: The block model is orthogonal with a parent block size of 10 m × 10 m × 5 m. The model was constructed using Seequent's Leapfrog Geo/Edge software. At the Mosquito Hill Deposit 60 drill holes totalling 6,138.88 metres were used to define the MRE. At the Reid Deposit 21 drill holes totalling 3,135.67 metres were used to define the MRE.

8. Grade Estimation: Gold grades (capped at 5.0 g/t Au) were estimated into the block model using Ordinary Kriging (OK) as the primary interpolation method. The estimation was performed in four passes with progressively relaxed search ellipsoid dimensions. A fixed ellipsoid orientation of Dip 15° / Dip-Azimuth 190° / Pitch 100° was applied across all passes, consistent with the variogram model and deposit geometry. A maximum of 3 composites per drill hole was enforced in Passes 1 through 3. Combined with the minimum sample requirements, this implicitly guarantees that each block is informed by composites from at least 3 independent drill holes in Passes 1 and 2 (minimum 9 samples ÷ max 3 per hole), and at least 2 drill holes in Pass 3 (minimum 6 samples ÷ max 3 per hole). The drill hole limit was disabled in Pass 4; blocks estimated in Pass 4 therefore carry no minimum drill hole constraint and a single drill hole may inform the entire block estimate. ID3 and Nearest Neighbour (NN) methods were used for validation purposes.

9. Compositing: Assay results were composited into 5 m downhole intervals within the mineralized wireframe. Intervals shorter than 0.5 m were distributed equally between the two adjacent composites. A hard boundary constraint was applied at the wireframe; composites outside the wireframe were not used to estimate blocks within the mineralized solid.

10. CIM Guidelines and Standards: The Mineral Resources described above have been prepared in accordance with the current CIM Definition Standards on Mineral Resources and Mineral Reserves (2014) and CIM Best Practice Guidelines (2019).

11. Rounding: Numbers have been rounded to reflect the appropriate level of precision. Differences may occur in totals due to rounding.

12. Mineral Resources are not Mineral Reserves: Mineral Resources are not Mineral Reserves as they have not demonstrated economic viability. The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as Indicated or Measured.

13. Material Factors: The Qualified Persons have not identified any known legal, political, environmental, or other relevant factors that could materially affect the potential development of the mineral resources or the validity of this estimate.

EXPLORATION POTENTIAL

Under NI 43-101, Exploration Potential at Mosquito Hill refers to areas in and around the Mosquito Hill Deposit where limited drilling has outlined conceptual tonnage and grade ranges where insufficient exploration has occurred to define a categorized mineral resource. When sufficient evidence of mineralization is determined, Exploration Potential could be upgraded to Inferred, Indicated, or Measured resources; however, it is uncertain if further exploration will result in the Exploration Potential being delineated as a mineral resource.

The extent of the Exploration Potential and the tonnage and grade ranges for the Mosquito Hill Deposit shown in Table 2 and Figure 9 and Figure 10, are based on current knowledge of the deposit type, experience with modelling and estimating the Mosquito Hill Deposit, itself and the proximity of the potentially mineralized material to the categorized mineral resources of the Mosquito Hill Deposit. The Mosquito Hill Deposit remains open along strike and at depth.
