Rocky Shore Drills 15.0 metres of 2.04 g/t Au Including 5.0 metres of 3.85 g/t Au, Announces Discovery of the Lucky 13 Gold Zone

TORONTO, ON / ACCESS Newswire / August 5, 2026 / Rocky Shore Gold Ltd. ("Rocky Shore" or the "Company") (CSE:RSG)(OTCQB:RSGLF) is pleased to announce the discovery of gold mineralization at the Lucky 13 Gold Zone identified during the Company's ongoing inaugural diamond drill program at the Lane Pond Gold Target, part of its 100%-owned Gold Anchor Project in central Newfoundland (see Map 1 below).

To date, the Lucky 13 Gold Zone has been intersected in numerous widely spaced drill holes along a potential strike length of 1,800 metres, a dip extent of up to more than 500 metres and ranges between 6.38 metres and 17.02 metres thick (interpreted to be approximately true thickness). The zone remains open in all directions and is observed to have increasing gold grades at depth, based on drill results to date.

To date, a total of 25 holes, comprising 8,086 metres have been completed, with samples from 15 holes, comprising 4,866 metres assayed and reported (see Map 2 below). Three holes (LP-26-01, 02 and 07) were reported in a news release dated June 10, 2026. Results from the remaining holes will be released when available. The Lucky 13 Gold Zone results are highlighted below (see Table 1 for full results).

• 15.02 metres grading 2.04 g/t Au, including 5.00 metres grading 3.85 g/t Au (LP-26-13)

• 17.02 metres grading 0.65 g/t Au, including 8.70 metres grading 1.02 g/t Au (LP-26-07)

• 13.00 metres grading 0.71 g/t Au, including 4.00 metres grading 1.37 g/t Au (LP-26-12)

• 14.40 metres grading 0.60 g/t Au, including 6.10 metres grading 1.00 g/t Au (LP-26-19)

• 8.11 metres grading 0.84 g/t Au, including 5.03 metres grading 1.10 g/t Au (LP-26-02)

• 14.91 metres grading 0.44 g/t Au, including 3.99 metres grading 1.10 g/t Au (LP-26-01)

Key Highlights

• Discovery of the Lucky 13 Gold Zone, interpreted as an orogenic hydrothermal gold system is associated within the Appleton Fault Corridor associated with an 11.0-kilometre-long geophysical anomaly termed the Lane Pond Gold Target. Only 15% of the Lane Pond Gold Target has been tested with shallow drill holes.

• Drill hole LP-26-13 represents the highest-grade (15.02 m grading 2.04 g/t Au) and deepest gold intersection (~300 metres vertical - see Map 3 below). Drilling at depth intersected a more intensely brittle-deformed interval characterized by stronger quartz veining, stockwork development, increased silicification, and substantially higher gold grades than holes drilled near surface.

• A progressive change caused by structural upgrading within the Lucky 13 Gold Zone, from predominantly ductile to a brittle overprinting at depth, was observed in drill holes LP-26-12 and 13.

• The Lane Pond Gold Target now supports an emerging model in which localized structural reactivation and upgrading exists within a broad, orogenic, fertile, extensive hydrothermal corridor which may preferentially host higher-grade gold mineralization.

Ken Lapierre, President and CEO of Rocky Shore Gold, commented, "The Lane Pond Gold Target now hosts the Lucky 13 Gold Zone, an extensive hydrothermal gold-bearing system associated with the Appleton Fault Corridor. The Appleton Fault Corridor trends across the entire Gold Anchor Project for over 60 kilometres based on current geological interpretation. This corridor could provide an important conduit to transport and deposit multiple gold discoveries throughout the Gold Anchor Project. These initial drill observations provide the first real evidence that localized structural reactivation and upgrading exists within the corridor and that the discovery of similar geological settings elsewhere across the 11-kilometre-long Lane Pond Gold Target and within Gold Anchor is excellent."

*Holes 3, 4, 9, 15-18 reported no significant assay results targeting undrilled geophysical anomalies. Holes 5, 6, 10, 14, 20-25 assays are pending. Hole 21 was abandoned due to caving and did not reach the intended target.

Quality Control and Reporting Protocols

All samples are collected and prepared for shipment in the field for submission to Eastern Analytical Ltd. in Springdale, Newfoundland, an ISO 17025 Certified Analytical Testing Facility, for 34 Element ICP Analysis. Eastern Analytical is independent of Rocky Shore. Blank and Certified Reference Material (CRM) are included, such that for every 18 samples, 1 blank and 1 CRM are included. Samples are shipped directly by in-field personnel, who maintain the chain of custody until samples are delivered to the laboratory. Rock preparation at the lab involves crushing up to 3 kg to 80% passing 10 mesh, 250 grams split, and pulverizing to 95% passing 150 mesh. For gold analysis, a 30 g sample is subjected to a fire assay, digested in aqua regia, and analyzed by atomic absorption (AA).

Qualified Person

The scientific and technical information in this press release has been prepared and approved by Ken Lapierre, P.Geo., President and CEO of the Company, and a Qualified Person in accordance with the Canadian regulatory requirements as set out in National Instrument 43-101. Mr. Lapierre consents to the publication of this press release dated August 5, 2026, by Rocky Shore Gold Ltd.

About Rocky Shore Gold Ltd.

Rocky Shore Gold is a Canadian junior exploration company focused on its 100%-owned Gold Anchor Project in central Newfoundland. It is strategically located within one of Canada's most promising and underexplored gold belts. The Project is the second-largest property (greater than 1,200 square kilometres) in this emerging gold district. Rocky Shore is targeting the expansion of its structurally controlled, orogenic-hosted, surface bulk-tonnage Mosquito Hill and Reid Gold Deposits, associated with the Dog Bay Line Fault. It also hosts orogenic, structurally controlled gold targets including the Lucky 13 Gold Zone along the highly prospective Appleton Fault Corridor located on trend and southwest of major gold discoveries and deposits.
