Drill Results Summary - Significant drill results from the Pitarrilla project include: - Hole BPU-022: 129 gpt Ag, 0.84% Pb, and 2.55% Zn for 242 gpt AgEq over 247 m, with high-grade intervals of 716 gpt Ag, 4.19% Pb, and 6.61% Zn for 1,062 gpt AgEq over 1.00 m [4][14]. - Hole BPD-505: 1,127 gpt Ag, 1.40% Pb, and 4.36% Zn for 1,319 gpt AgEq over 2.08 m ETW, including 4,630 gpt Ag, 2.26% Pb, and 3.49% Zn for 4,814 gpt AgEq over 0.20 m ETW [7][12]. - Hole BPD-506: 893 gpt Ag, 2.06% Pb, and 2.56% Zn for 1,038 gpt AgEq over 3.97 m ETW, with a notable interval of 5,090 gpt Ag, 9.22% Pb, and 0.84% Zn for 5,363 gpt AgEq over 0.23 m ETW [7][12]. Geological Context - The Pitarrilla deposit features three mineralized domains and at least four identified sulphide mineralized veins (Casas Blancas, Victoria, Danna, and Palmito) [5][6]. - The mineralized structures extend from below marine sediments through Manto Pitarrilla into the upper volcanics, remaining open at depth [6][21]. Project Overview - The Pitarrilla project is a large undeveloped silver, lead, and zinc project located 160 kilometers north of Durango City, covering 4,752 hectares across five concessions [23]. - The project has significant infrastructure and key permits in place for underground mining and development, including water use and discharge, explosives use, and soil change [23]. Company Background - Endeavour Silver is a mid-tier precious metals company focused on sustainable mining practices, with operations in Mexico and Peru, and aims to become a premier senior silver producer [24].
