Rocky Shore Discovers New Bulk-Scale MTH Gold Zone, Reports Record High-Grade Intercept at Mosquito and Expands Drill Program to 20,000 Metres

Gold mineralization now extends beyond the Mosquito resource limits, while assays from additional drill holes remain pending.

Rhea-AI Summary

Rocky Shore Gold (RSGLF) discovered the MTH gold zone at its Gold Anchor Project and expanded its drill program to 20,000 metres. The Newfoundland discovery extends mineralization more than 400 metres east of the Mosquito Deposit’s current resource limits and remains open in all directions.

MTH drilling returned 154.78 metres at 0.34 grams of gold per tonne in MH-26-05 and 50.00 metres at 1.01 grams per tonne in MH-26-06. MH-26-08 returned 144.40 metres at 0.34 grams per tonne, including 48.90 metres at 0.73 grams per tonne. At Mosquito, MH-26-02 returned 94.10 metres at 0.77 grams per tonne, including 2.50 metres at 7.88 grams per tonne. The company interprets Mosquito and MTH as potentially part of a larger mineralized system. More than 60% of the interpreted intrusion associated with Mosquito remains untested; assays for MH-26-09 through MH-26-13 are pending.

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 26, 2026 / Rocky Shore Gold Ltd. ("Rocky Shore" or the "Company") (CSE:RSG)(OTCQB:RSGLF) is pleased to report the discovery of the MTH Zone at its Gold Anchor Project in central Newfoundland. Drilling intersected a thick, sulphide-rich tuffaceous sedimentary horizon in a previously undrilled area immediately east of the Mosquito Deposit resource limits. The MTH Zone remains open in all directions and is associated with a large geophysical anomaly. The discovery expands the known footprint of gold mineralization beyond the current Mosquito Deposit resource limits and indicates that the Mosquito Deposit and MTH Zone may form part of a larger mineralized bulk-scale setting. In addition, confirmation drilling within the Mosquito Deposit returned the highest-grade interval to date within the deposit; 94.10m grading 0.77 g/t Au, including 2.50m grading 7.88 g/t Au in hole MH-26-02 (see Maps 1, 2 and 3 below).

Gold intervals within the newly discovered MTH Zone are highlighted below. For a complete record of drill results, refer to Table 1 below. Based on the current geological interpretation, reported drill hole thicknesses are estimated to approximate true thickness.

• 154.78m grading 0.34 g/t Au including 11.40m grading 1.01 g/t Au (MH-26-05)
• 50.00m grading 1.01 g/t Au including 4.70m grading 2.75 g/t Au (MH-26-06)
• 90.65m grading 0.33 g/t Au including 14.90m grading 0.83 g/t Au (MH-26-07)
• 48.90m grading 0.73 g/t Au including 6.65m grading 1.65 g/t Au (MH-26-08)

Gold intervals within the Mosquito Deposit resource limits are highlighted below. For a complete record of drill results, refer to Table 1 below. Based on the current geological interpretation, reported drill hole thicknesses are estimated to approximate true thickness:

• 33.20m grading 1.07 g/t Au including 6.20m grading 2.01 g/t Au (MH-26-01)
• 94.10m grading 0.77 g/t Au including 2.50m grading 7.88 g/t Au (MH-26-02)
• 59.20m grading 0.49 g/t Au including 11.00m grading 1.00 g/t Au (MH-26-03)
• 19.87m grading 0.41 g/t Au including 1.10m grading 2.46 g/t Au (MH-26-04)

Key Takeaways:

• The MTH Zone comprises a thick, gold-bearing sedimentary horizon that remains open in all directions;
• Drilling has traced the MTH Zone from the eastern limit of the Mosquito Deposit to more than 400 metres east of the current resource limits;
• Confirmation drilling at the Mosquito Deposit returned the highest-grade interval to date within the deposit; 94.10 m grading 0.77 g/t Au, including 2.50 m grading 7.88 g/t Au;
• More than 60% of the interpreted intrusion associated with the Mosquito Deposit remains untested by drilling; and
• Drilling indicates that the Mosquito Deposit and MTH Zone may form part of a larger and more complex bulk scale mineralized system extending beyond the current resource limits.

Rocky Shore's President & CEO Ken Lapierre commented, "The discovery of the MTH Zone is changing our understanding of the Gold Anchor system. While the Mosquito Deposit delivered encouraging results, drilling on the MTH Zone is now demonstrating that gold mineralization extends well beyond the current resource limits into a broader mineralized setting. With multiple expansion opportunities emerging and significant portions of the system still untested, increasing the program to 20,000 metres is a logical next step as we continue to evaluate the scale of Gold Anchor."

Map 1: A large-scale setting has emerged where the porphyry intrusive footprint (white colour with light black dash lines around its perimeter) extends well beyond the porphyry-hosted Mosquito Deposit (transparent grey colour with thick dashed black lines). The MTH Zone (red star) is associated with a distinct resistivity anomaly (purple hues) east of the present resource limits. Both the anomaly which wraps around the intrusion and the remaining untested porphyry intrusive footprint remains untested.

FAQ

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

What did Rocky Shore Gold discover at the MTH Zone?

Rocky Shore discovered a gold-bearing sedimentary horizon east of the Mosquito Deposit’s current resource limits at Gold Anchor. Drilling traced mineralization more than 400 metres east of those limits. The zone remains open in all directions and is associated with a large geophysical anomaly.

What did Rocky Shore Gold report from Mosquito drill hole MH-26-02?

MH-26-02 returned 94.10 metres at 0.77 grams of gold per tonne, including 2.50 metres at 7.88 grams per tonne. Within that interval, a 1.05-metre section graded 17.20 grams per tonne.

Do Rocky Shore Gold’s reported drill lengths approximate true thickness?

Based on the current geological interpretation, the reported drill-hole thicknesses are estimated to approximate true thickness. This estimate applies to the highlighted intervals at both the MTH Zone and the Mosquito Deposit.
