Doubleview Provides Cobalt Resource Summary for the Hat Polymetallic Deposit in Advance of Updated MRE and PEA

Core Viewpoint - Doubleview Gold Corp. is preparing to release an updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA) for the Hat Polymetallic Deposit, highlighting its significant cobalt resource as a key component of the project [1][4]. Cobalt Resource Summary - The Hat Deposit is noted to potentially contain one of the largest undeveloped cobalt inventories in Canada, with cobalt occurring as a by-product associated with copper and pyrite mineralization [2][4]. - The indicated resource includes 150 million tonnes with 28 million pounds (approximately 12,700 tonnes) of cobalt at a grade of 0.008% Co, while the inferred resource consists of 477 million tonnes with 91 million pounds (approximately 41,300 tonnes) of cobalt at a grade of 0.009% Co [6][11]. Metallurgical Insights - Cobalt is consistently distributed throughout the alkalic porphyry system alongside other metals, and metallurgical tests indicate efficient liberation of cobalt into a clean pyrite concentrate suitable for conventional processing [3][4]. Strategic Importance of Cobalt - Cobalt is classified as a critical mineral by several countries, including Canada and the United States, and is essential for high-performance lithium-ion batteries, superalloys, and clean-energy technologies [5][7]. - The Hat Deposit's location in a Tier-1 jurisdiction and its substantial cobalt endowment enhance its long-term relevance as demand for responsibly sourced battery metals increases [4][8]. Project Development Context - The Hat Deposit has undergone multiple exploration campaigns and is expected to advance through necessary evaluation and development stages, potentially contributing to future domestic cobalt supply [8][10].
