TORONTO, ON / ACCESS Newswire / October 19, 2026 / Rocky Shore Gold Ltd. ("Rocky Shore" or the "Company") (CSE:RSG)(OTCQB:RSGLF) is pleased to report that additional assays from widely spaced drill holes at the Lane Pond Gold Target have identified antimony in the newly named Lucky 13 Au-Sb Zone. The zone is associated with an 11.0-kilometre-long, district-scale airborne VTEM anomaly within the highly prospective Appleton Fault Corridor. The Company's 100%-owned Gold Anchor Project in central Newfoundland hosts two bulk-tonnage, open-pit gold deposits and the Lucky 13 Au-Sb Zone, which lies along trend from major high-grade gold discoveries northeast of the project boundary (see Maps 1, 2 and 3).

Significant gold (Au) and antimony (Sb) results represent near true thicknesses (see Table 1 for complete drill results):

• 31.64m grading 1.39 g/t AuEq (0.50 g/t Au, 0.30% Sb), including 4.00m grading 5.58 g/t AuEq (0.67 g/t Au, 1.62% Sb) (LP-26-12)
• 15.02m grading 2.71 g/t AuEq (2.04 g/t Au, 0.25% Sb), including 3.02m grading 4.69 g/t AuEq (0.98 g/t Au, 1.23% Sb) (LP-26-13)
• 17.02m grading 0.71 g/t AuEq (0.65 g/t Au, 0.10% Sb), including 8.70m grading 1.12 g/t AuEq (1.02 g/t Au, 0.05% Sb) (LP-26-07)
• 14.40m grading 0.66 g/t AuEq (0.59 g/t Au, 0.03% Sb), including 6.10m grading 1.12 g/t AuEq (1.00 g/t Au, 0.06% Sb) (LP-26-19)

Key preliminary takeaways of the Lucky 13 Au-Sb Zone:

• Widely spaced drill holes have identified antimony and gold over a 400m strike length and 450m dip extent (holes 7, 12, 13 and 19);
• Drilling to date indicates that antimony and gold grades increase with depth;
• Higher-grade gold-antimony mineralization is associated with brittle deformation, silicification, quartz stockwork and sulphides; and
• The Lucky 13 Au-Sb Zone remains open in all directions.

Ken Lapierre, P.Geo., President and CEO of Rocky Shore, commented, "The unexpected discovery of antimony, a critical mineral, is an exciting development. Widely spaced drilling at Lucky 13 has now intersected both gold and antimony. Higher-grade intervals include 4.00 metres grading 5.58 g/t AuEq (0.67 g/t Au, 1.62% Sb) within a 31.64-metre mineralized envelope grading 1.39 g/t AuEq (0.50 g/t Au, 0.30% Sb). The zone is associated with an extensive, largely untested 11.0-kilometre-long airborne VTEM anomaly with an apparent dip extent of at least 1,000 metres. The property continues to exceed our expectations, delivering positive results and new discoveries. While we await additional assays from the Lucky 13 Au-Sb Zone, drilling continues 5.0 kilometres west of the discovery, in and around the nearby Mosquito Gold Deposit. We look forward to reporting further results from both areas in the coming weeks."

At the Lane Pond Gold Target, a total of 25 holes, comprising 8,086 metres, were completed, with samples from 18 holes, comprising 5,826 metres, assayed and reported. Three holes (LP-26-01, 02 and 07) were reported in a news release dated June 10, 2026. Twelve holes (LP-26-3, 4, 8, 9, 11-13, 15-18) were reported in a news release dated August 5, 2026. Remaining holes will be released when available. Table 1 below highlights the updated results for the Lucky 13 Au-Sb Zone.

Table 1: Updated drill summary table with gold and antimony results. Please refer to the news release dated August 20, 2026 for gold-only grades. The lengths below are estimated to be near true thickness.

*Holes 3, 4, 5, 6, 9, 14-18, and 22 reported no significant assay results. Holes 10, 20, 21, and 23-25 assays are pending. Hole 21 was abandoned due to caving and did not reach the intended target. Au values and thicknesses were known before upgrading with Sb values (see the news release dated August 20, 2026, for gold-only intervals).

**Metal equivalent grades (AuEq) are for illustrative purposes only to express the combined value of gold and antimony as a single metal grade. Metal equivalent grades are calculated using USD$4,250/oz gold and USD$21/pound (two-year moving U.S. average (2024-2026). Metallurgical recoveries are assumed to be 95% for gold and 90% for antimony. The following equation is used to calculate AuEq = (percent Sb/100 X lbs/tonne X price per pound Sb X recovery)/price of Au per gram + (gpt Au X recovery).
