Sidney Resources Confirms Successful Metallurgical Isolation of Iridium at Warren District Sidney Resources Confirms Successful Metallurgical Isolation of Iridium at Warren District WARREN, ID / ACCESS Newswire / January 12, 2026 / Sidney Resources Corporation (OTCID:SDRC) ("Sidney" or the "Company") is pleased to report a significant metallurgical milestone achieved through ongoing processing and testing at its Warren District project in Idaho. Recent work has successfully produced metallic smelter "buttons" containing iridium, marking a key technical advancement in the Company's polymetallic development program.Figure 1: Heavy mineral concentrate prior to smelting. Material shown has been upgraded through gravity separation and represents pre-concentrated feed rather than raw ore. This step physically increases metal content prior to thermal processing. The smelter buttons represent the final product of gravity separation followed by smelting and are not raw rock or unprocessed concentrate. This progression - from mineralized material to physically isolated metal - reflects the transition from geochemical identification to demonstrable metal recovery, a critical step in reducing technical risk at the project level.Figure 2 : Microscopic view of bronzite-rich concentrate prior to smelting.Angular silicate grains are visible alongside dense metallic phases. The heterogeneous texture is consistent with platinum group metal (PGM) systems, where ultra-rare metals such as iridium occur in localized grains rather than uniformly distributed. Iridium is among the rarest elements on Earth, estimated to be approximately 40 times rarer than gold, with global annual production of roughly 7-10 tonnes. The metal is considered strategically important due to its use in defense, aerospace, nuclear, and advanced electronics applications. At present, the United States has no meaningful domestic primary supply of iridium.Figure 3: Concentrate during active smelting. Elevated temperatures allow dense metallic phases to coalesce while silicate material separates into slag, producing recoverable metallic smelter "buttons" used for analytical testing. Independent energy-dispersive X-ray fluorescence (ED-XRF) testing conducted on the smelter buttons confirms iridium present in concentrated material at approximately 390 to 1,120 parts per million (ppm), equivalent to roughly 12.5...
