North Shore Engages Drill Contractor and Continues to Advance Rio Puerco Project

North Shore announced that it has engaged Harris Exploration Drilling & Associates to execute an up‑to‑27‑hole rotary drilling program at its Rio Puerco uranium project in New Mexico. The program is slated to start in May 2026, pending receipt of a Minimal Impact Exploration Operation Permit and a BLM Notice of Intent. The drill plan will twin historic Kerr‑McGee holes to validate the 2009 JORC‑inferred resource (6 Mt @ 0.09% eU₃O₈ ≈ 11.4 M lb U₃O₈) and test for expansion, with an aim to produce a NI 43‑101 compliant resource update.

• Nature of the announcement: Operational preparation – no immediate cash flow or financing effect.
• Expectation vs. reality: The drill‑program engagement was already hinted at in earlier updates (Feb 23 and Feb 11) that described permitting activity and a planned May start. This release simply confirms the contractor and adds detail on the drilling partner’s uranium experience.
• Market impact: Because the news does not alter the company’s balance sheet, cash position, or resource estimate, it is non‑material to valuation. It is a positive operational step but fully expected by investors tracking the Rio Puerco timeline.

Conclusion: The announcement is routine and positive; no material re‑rating of the stock.
