Core Insights - Corcel Exploration Inc. has identified significant historical occurrences of critical minerals, tungsten and graphite, at its Yuma King Project in Arizona, based on historical mining data and assessments [1][3][6] - The U.S. government classifies tungsten and graphite as critical minerals, essential for manufacturing, energy technologies, and defense systems, with the country currently relying on foreign sources for both [6][16] Historical Tungsten Occurrences - Tungsten was historically mined from several prospects within the Yuma King Project area, including the Three Musketeers, Jewel Anne, Pee Wee, Ace, and Trioni claims, with production occurring intermittently from the early 1950s through the 1970s [3][6] - Sampling indicates tungsten-bearing structures are present over an area of approximately 5 square kilometers, with high-grade pods returning assays up to 19.15% WO3 [6][11] - Broad tungsten-in-soil anomalies have been identified, extending beyond the historical mining areas, indicating broader district potential [6][11] Graphite and Graphene Mineralization - Graphite mineralization was first identified in 2011, with significant intervals reported up to 150 meters thick and a 25-meter zone containing high carbon content confirmed by Raman spectroscopy [6][11][12] - Follow-up drilling in 2016 demonstrated that the mineralized horizon extends southward, identifying additional graphite-bearing zones [12][13] - The graphite mineralization is interpreted to be related to thrust-related deformation and metamorphism during the early Laramide orogeny [13] U.S. Critical Minerals Context - The U.S. is entirely reliant on imports for tungsten and graphite, which are recognized as essential to national defense and various technological applications [6][16] - Tungsten is utilized in electronics and defense systems, while graphite is crucial for lithium-ion battery anodes and energy storage technologies [16] Evaluation of Critical Minerals at Yuma King - The company plans to incorporate historical tungsten and graphite datasets into the broader geological model for the Yuma King Project, assessing whether these critical mineral systems warrant further evaluation alongside copper-gold exploration [16][17]
