Sidney Resources Corporation (OTC: SDRC) – Progress Update Warren Mining District, Idaho October 2025 – March 2026 Over the past six months, Sidney Resources Corporation has delivered consistent, high-impact advancements across its flagship Warren Project in Idaho’s historic Warren Mining District. Focused on high-grade gold-silver systems, rare earth elements (REEs), critical metals, and platinum-group metals (PGMs), the Company has executed a disciplined strategy of land consolidation, metallurgical innovation, geophysical confirmation, and forward planning. These milestones position $SDRC as a leader in sustainable, multi-commodity mineral development in the U.S., with clear pathways to resource definition, test-scale production, and strategic partnerships. Key Milestones (Chronological) October 28, 2025 – Breakthrough Metallurgical Results Initial processing tests demonstrated exceptional REE recoveries via gravity and leach methods, achieving up to 30% total rare earth oxide (TREO) concentrates from gravity separation and over 60% via leaching. These results highlighted synergies with gold and silver extraction, validating the multi-metal potential of Warren District material. November 4, 2025 – Confirmation of Exceptional Rare Earth & Critical Metal Concentrations Detailed laboratory assays and oxide-conversion data confirmed outstanding grades of REEs, tungsten (W), and PGMs in processed samples from the Warren District. CEO Sean-Rae Zalewski noted that the results provided “deeper clarity and confidence” for investors and partners, with full metallurgical reports underscoring the project’s strategic importance for domestic critical minerals supply. December 9, 2025 – Major Land Expansion The Company staked 371 new claims, adding approximately 7,600 acres to its holdings. This expansion increased regional control by over 500% and specifically targeted REE-bearing pegmatites alongside historic gold-silver vein systems. The move significantly strengthens SDRC’s district-scale footprint and future exploration upside. January 12, 2026 – Successful Metallurgical Isolation of Iridium Ongoing processing and smelting tests at the Warren District achieved a major technical milestone: the successful isolation and enrichment of iridium (a high-value PGM) in metallurgical buttons. This breakthrough further demonstrates the project’s polymetallic potential and the effectiveness of Sidney’s proprietary extraction approaches. February 18, 2026 – 2026 Strategic Objectives Outlined Sidney published its comprehensive 2026 roadmap, centered on high-grade gold advancement while maintaining disciplined development of REE and critical metal assets. Priorities include: Underground drifting and drilling at the Lucky Ben mine to support a maiden mineral resource estimate (MRE) targeted for Q4 2026–Q1 2027. Scaling REE processing to produce >30% TREO concentrates, with potential shipment of up to 20,000 lbs to a U.S. Department of Defense laboratory. Pursuit of federal grants (e.g., NETL/DOE programs) and commercialization of advanced technologies such as laser spallation. Test-scale gold production and monetization pathways. The plan emphasizes operational efficiency, regulatory compliance, and value creation for shareholders. March 24, 2026 – District-Scale Structural & Hydrothermal System Identified An airborne magnetic and radiometric survey confirmed a district-scale structural and hydrothermal system at Warren. Results validate that Sidney’s expanded claims sit directly within the core target corridor, revealing multiple new high-priority drill targets and underscoring the project’s potential for large-scale mineralization. Marketing & Communications Activity Throughout the period, $SDRC maintained an active and transparent outreach program via: Regular press releases distributed through ACCESS Newswire and carried by Yahoo Finance, OTC Markets otcmarkets.com/stock/SDRC/ove…, StockTitan, and other platforms. Updates on the company website (sidneyresources.com). Social media engagement (including X @SDRCMINING) highlighting technical successes and strategic positioning. Investor-focused materials, including Q3 2025 highlights and filings on OTC Markets. These efforts have driven strong visibility, with SDRC frequently ranking among top-performing micro cap mining stocks in early 2026 @mining . Looking Ahead The last six months reflect a transformative phase for Sidney Resources Corporation—from metallurgical proof-of-concept and aggressive land acquisition to geophysical validation and a clear 2026 execution plan. With a strengthened position in both precious metals and critical minerals, disciplined capital allocation, and advancing technical capabilities, the Company is well-positioned to unlock the full value of the Warren District while contributing to U.S. supply chain security. This progress underscores SDRC’s transition from pure exploration toward development and production readiness. Continued updates will be shared through official channels as milestones are achieved.
