Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) announces that it has intercepted high grade silver-gold mineralization in a number of structures near the Terronera vein, highlighting the potential of the area. Four structures, the San Simon, Fresno, Pendencia and Lindero veins are located immediately to the southeast of the Terronera vein, and the Los Cuates vein is located approximately 10 kilometers to the northwest of the Terronera Project (view Terronera property map here).
The drill results reported today represent ongoing exploration work at the Terronera Project, with a plan to complete 16,000 metres of drilling by the end of the year. Key targets include extensions of the Terronera vein, which hosts most of the reserves in the Terronera Feasibility Study that is currently in progress, and more regional targets to grow resources in the district. As the Feasibility Study is nearing completion, all 2021 drill results will not be included as part of the development plan.
Highlights from each structure include:
Abbreviations include: gpt: grams per tonne; Au: gold; Ag: silver; ETW: estimated true width; m: metre; HW: hanging wall. Silver equivalents are calculated at a ratio of 70:1 silver:gold.
Luis Castro, Vice President of Exploration, commented, “These results support our view that the Terronera property continues to have significant potential to discover new mineralized zones and grow the mineral resources in multiple veins proximal to the already defined reserves and resources in the main Terronera vein. Over the past couple years, our drill programs have focused solely on delineating reserves and resources within the main Terronera vein to increase the level confidence for the Feasibility Study. During this time, surface exploration work was performed to develop and prepare additional targets in the region. These drill results verify that our detailed, methodical approach continues to be the right approach.”
Significant drill results are summarized in the following table. The Company has drilled 33 drill holes totalling 9,369 metres on the above regional targets over the past 8 months.
