Endeavour Silver Provides Pitarrilla Project Update

Core Viewpoint - Endeavour Silver Corp. is advancing its exploration and evaluation initiatives at the Pitarrilla project, focusing on high-grade mineralization and preparing for a future economic study by the end of 2025 [1][6][16]. Exploration and Development - Since acquiring the Pitarrilla project in July 2022, the company has re-logged historic drill core to enhance understanding of the geology and mineralization controls, identifying high-grade feeder structures for silver, lead, and zinc [2][5]. - The company has refurbished an underground ramp extending over 1.3 kilometers, confirming the presence of at least four significant structures: Palmito vein, Danna vein, Victoria vein, and Casas Blancas vein [3][4]. - Nine diamond drill holes have been completed since August, successfully intersecting targeted mineralization, which supports the potential for underground bulk tonnage mining [4][5]. Mineral Resource Estimates - The primary feeder veins have a vertical extent of approximately 600 to 800 meters and strike lengths nearing 700 meters, with the Danna vein being the largest at approximately 800 meters vertical and 500 meters strike length [5][6]. - The combined favorable grades and continuity of the deposit make it attractive for underground bulk mining, with ongoing drilling and development work validating the geological model [6][16]. Technical Studies and Future Plans - Engineering firms have been retained to conduct preliminary work, including metallurgical testing, mine design, and hydrology investigations, building on previous work by SSR Mining [6][16]. - The project has significant infrastructure and key permits in place for underground mining, including water use and discharge, explosives use, and environmental impact assessments [16][17]. Company Overview - Endeavour Silver is a mid-tier precious metals company committed to sustainable mining practices, with operations in Mexico and a portfolio of exploration projects in Mexico, Chile, and the United States [17].
