Sidney Resources Expands Warren District Footprint With 380 New Claims Targeting REE-Bearing Pegmatites and Historic Gold-Silver Systems Sidney Resources Expands Warren District Footprint With 380 New Claims Targeting REE-Bearing Pegmatites and Historic Gold-Silver Systems WARREN, ID / ACCESS Newswire / December 9, 2025 / Sidney Resources Corporation (OTCID:SDRC) ("Sidney" or the "Company") is pleased to announce a major expansion of its land position in Idaho's historic Warren Mining District. Following the Company's confirmation of exceptional high-grade rare earth element (REE) and critical metal concentrations within the Knott Vein and Lucky Ben systems, Sidney has officially initiated the staking of 380 new federal mining claims, representing approximately 7,600 acres of additional mineral rights. This expansion is designed to secure newly identified geological structures, pegmatite corridors, and historically productive precious-metal zones that are now recognized as part of a broader, district-scale mineral system. With this expansion, Sidney Resources reaffirms its position as one of the most dominant and historically established mineral rights holders in the Warren District.

Expansion Driven by New Geological Insights and REE Breakthrough Results The Company's recent laboratory results confirming: 30% TREO Gravity Concentrates, and 60-65% TREO Leach Residuals have reshaped the modern geological interpretation of the Warren District. Subsequent mapping and structural analysis have identified significant pegmatite dikes and pegmatitic structural zones throughout the region-host environments globally associated with REEs, lithium, tantalum, niobium, and other critical elements. Their presence strongly supports an evolved magmatic-hydrothermal system capable of producing both precious and critical minerals across a wide regional footprint. These findings directly integrate with the Company's breakthrough REE results and demonstrate that Warren's mineralized system extends beyond the known Knott Vein and Lucky Ben structures. Strategic Purpose of the Expansion The 380-claim expansion was designed to achieve two core objectives: 1. Capture REE-Prospective Pegmatite Corridors These...
