Exploration Drilling Underway at Silver Dollar's La Joya Silver (Copper-Gold) Project

Executive Summary of Recent Activity

• Most Recent News (2026-04-20): Silver Dollar Resources has commenced a 3,500-metre diamond drilling program at its La Joya Silver Project in Durango, Mexico. The company states it is fully funded for 2026 and intends to expand the program as results are received.
• Drilling Targets: The campaign targets deep San Martin-type mineralization within the Noria portion of the complex, specifically testing Central Dyke, El Brazo, North Side, Road Zone, and El Puerto Mag Anomaly.
• Historic Context: Previous sampling at La Embotelladora (Nov 2025) showed high-grade intercepts up to 2,753 g/t AgEq. Historic drill holes show grades like 694 g/t AgEq over 8.6m at depth.
• Funding Status: The company is fully funded for the year following a $5.9 million private placement closed in October 2025 led by Research Capital Corp., with significant participation from Eric Sprott.

Historical Progression of Projects

• October 2025 Financing: Raised $5.9M at $0.35/unit, increasing Eric Sprott's stake to ~17.5% non-diluted. Proceeds earmarked for La Joya and Ranger-Page exploration.
• December 2025 Asset Sale: Completed sale of Ranger-Page Project to Bunker Hill Mining Corp. for $5.8M in shares (escrowed over 12 months). This consolidated land packages but removed an asset from Silver Dollar's balance sheet.
• January 2026 Exploration Plan: Outlined five priority targets at La Joya, confirming the shift from open-pit to underground exploration focus.
• March 2026 Contractor Hired: Engaged Versa Perforaciones for the 3,500m diamond drilling program.

Evaluation of Most Recent News

• Materiality Level: Routine - Positive. The commencement of drilling is an execution milestone rather than a discovery event. It confirms the company's funding status and operational progress but does not introduce new assay data or resource estimates that would fundamentally alter valuation immediately.
• Expectations vs. Reality: This news aligns with previous announcements (Jan 2026 plan, Mar 2026 contractor hire). There are no surprises regarding timing or scope. The market had already priced in the financing and asset sale by January 2026 (peak price $0.68), suggesting this execution phase is expected.
• Impact on Stock Price: Likely neutral to slightly positive short-term as it removes capital risk uncertainty, but significant upside requires assay results from the current drill program. The stock has corrected significantly from its January highs ($0.68) to current levels ($0.38), indicating prior optimism was exhausted.

Comparison with Historical Projections

• Funding: The "fully funded" claim in April 2026 matches the October 2025 financing announcement, validating management's capital planning.
• Project Focus: Consistent with the November 2025 shift to underground exploration and high-grade targets (e.g., La Embotelladora sampling).
• Asset Sale: The Ranger-Page sale in December 2025 provided liquidity but reduced asset base; current focus is entirely on La Joya, which aligns with the drilling news.
