Rocky Shore's Antimony Discovery Enhances Lucky 13 Gold Zone at Gold Anchor

Widely spaced holes identified gold and antimony across 400 metres of strike, while additional assays remain pending.

Rhea-AI Summary

Rocky Shore Gold (RSGLF) identified antimony alongside gold in additional assays from the Lucky 13 zone at its Gold Anchor Project. Hole LP-26-12 returned 31.64 metres grading 1.39 grams per tonne gold equivalent, including 4.00 metres at 5.58 grams per tonne. Gold equivalent expresses the combined gold and antimony value. Hole LP-26-13 returned 15.02 metres at 2.71 grams per tonne gold equivalent.

Widely spaced drilling identified both metals over a 400-metre strike length and 450-metre dip extent. The zone remains open in all directions and is associated with an 11.0-kilometre airborne electromagnetic anomaly. Rocky Shore said drilling indicates grades increase with depth. Lane Pond drilling comprised 25 holes totalling 8,086 metres; additional assays remain pending. Hole 21 was abandoned because of caving before reaching its target. Drilling continues around the Mosquito Gold Deposit, 5.0 kilometres west.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

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.

*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).

Quality Control and Reporting Protocols

Field personnel collect and prepare all samples for shipment directly to Eastern Analytical Ltd. in Springdale, Newfoundland, an ISO 17025-certified analytical testing facility independent of Rocky Shore. Chain of custody is maintained until laboratory delivery. Quality-control materials include one blank and one certified reference material (CRM) for every 18 samples. At the laboratory, up to 3 kg of rock is crushed to 80% passing 10 mesh; a 250 g split is then pulverized to 95% passing 150 mesh. For gold analysis, a 30 g sample undergoes fire assay, aqua regia digestion and atomic absorption (AA) analysis. For 34-element ICP analysis, 200 mg of sample material undergoes four-acid digestion followed by inductively coupled plasma (ICP) analysis. This method analyzes a suite of base metals, including antimony. Over-limit ICP results are reanalyzed by AA.

Antimony: A Critical Mineral

Antimony is considered a critical mineral because of its strategic importance to national defence, fire safety, energy storage, semiconductors and alloy strengthening, combined with a concentrated and vulnerable global supply chain.

About Rocky Shore Gold Ltd.

Rocky Shore Gold is a Canadian junior exploration company focused on its two 100%-owned projects in central Newfoundland: Gold Anchor and Rocky Pond VMS. Gold Anchor covers more than 1,200 square kilometres, making it the second-largest property in one of Canada's most prospective and underexplored emerging gold districts. The project hosts the near-surface, bulk-tonnage Mosquito and Reid orogenic gold deposits, as well as structurally controlled orogenic gold targets, including the Lucky 13 Au-Sb Zone along the highly prospective Appleton Fault Corridor. Gold Anchor lies southwest of, and along trend from, major gold discoveries and deposits. The Rocky Pond VMS Project lies within the Roberts Arm VMS Belt, which hosts the world-class former Buchans VMS mine. Rocky Pond hosts the gold-rich Handcamp VMS Zone and several additional VMS showings along a 40-kilometre trend of this prolific belt.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What gold and antimony grades did Rocky Shore report at Lucky 13?

Hole LP-26-12 returned 31.64m containing 0.50 g/t gold and 0.30% antimony, equivalent to 1.39 g/t gold equivalent. Its included 4.00m interval contained 0.67 g/t gold and 1.62% antimony. Hole LP-26-13 returned 15.02m containing 2.04 g/t gold and 0.25% antimony, equivalent to 2.71 g/t gold equivalent.

How does Rocky Shore calculate Lucky 13 gold-equivalent grades?

The illustrative calculation uses USD$4,250/oz gold and USD$21/pound antimony, with assumed metallurgical recoveries of 95% for gold and 90% for antimony. It converts the recovery-adjusted antimony value into a gold grade and adds the recovery-adjusted gold grade.
