Endeavour Silver Provides Pitarrilla Project Update

VANCOUVER, British Columbia, Nov. 13, 2024 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (“Endeavour” or the “Company”) (NYSE: EXK; TSX: EDR) is pleased to report an update on the 2024 exploration and evaluation initiatives at its 100% owned Pitarrilla project. Engineering firms have been retained to commence technical studies for the basis of a future economic study.

Since acquiring the Pitarrilla project in July 2022, Endeavour has re-logged historic drill core to further understand the geology and mineralization controls of the deposit. Priority has been focused on identifying and defining numerous high-grade feeder structures that are interpreted to be the source of the silver, lead and zinc sulphide mineralization, and that extend through the high-grade manto, originally identified by SSR Mining. The Company published a technical report dated November 21, 2022 outlining Mineral Resource Estimates (See news release dated December 8, 2022).

Endeavour has refurbished an existing underground ramp and extended it over 1.3 kilometres. The ramp has been developed through the projected feeder structures and crosscuts have been made for drill stations to further interpret and test the high-grade zones and its feeder structures with core drilling at various angles. The ramp lies directly above the manto. This work confirmed management’s interpretation and identified at least four structures that extend through the manto (Figures 1 and 2): Palmito vein, Danna vein, Victoria vein and Casas Blancas vein. During development of the ramp, additional mineralized structures were also identified, including the Norma vein, Danna hanging wall (HW) vein and Peña dike. Further work and interpretation are required to understand the significance and extent of these additional structures. In the ramp, the Peña dyke is the thickest structure with channel samples averaging 4.5 metres to 4.7 metres in width, oriented near perpendicular to strike. Results from the 16 channel samples are presented in Figure 3 and Table 3. 

Since August, the Company completed nine diamond drill holes, six from surface and three from underground drill stations. The three holes from underground were targeted to intersect the manto and multiple veins, while the holes drilled from surface were directed to intersect the Casas Blancas vein. All holes successfully intersected the targeted mineralization, supporting managements geological interpretation and the potential of underground bulk tonnage mining.

Based on the re-logging of historic drill holes resulting in re-interpreting the geologic model along with current activities, it is estimated that all four primary feeder veins have a vertical extent of approximately 600 to 800 metres and strike lengths approaching 700 metres; these veins appear open to depth. Danna is the largest vein with an approximate 800 metre vertical extent and a strike length approaching 500 metres. Thicknesses can vary but are typically three metres wide (ETW). This work is being performed to understand the potential for an underground bulk tonnage mining scenario, which would focus mining activities on the high-grade structures and manto.

"The combined favorable grades, strike length, vertical extent, and vein proximity, along with the manto’s size and continuity, make the deposit attractive for underground bulk mining," said Don Gray, Chief Operating Officer. "Our exploration team’s careful attention while relogging the historic drill results provided an alternative geologic model. Not only are ongoing drilling and underground development work confirming this model, but they are also validating our original decision to acquire Pitarrilla. We are quite confident Pitarilla will create significant shareholder value and prove to be Endeavour’s next cornerstone asset."

The Company is also pleased to announce that SGS Canada Inc., SGS Bateman, JDS Energy & Mining, T Engineering, Stantec and SRK Consulting have been retained to begin preliminary work on the project. This work will include the metallurgical testing program with a comprehensive review of historical test data, flowsheet evaluation, mine design, rock mechanics evaluation, backfill testing and design, hydrology investigations, and tailing storage facility design. The work will build on the SSR Mining’s extensive previous work and will be used to advance the project to the development stage, forming the basis for an economic study by the end of 2025.

Pitarrilla is a large undeveloped silver, lead, and zinc project located 160 kilometres north of Durango City, in northern Mexico. The project is within the Municipality of Santa María del Oro and Indé on the eastern flank of the Sierra Madre Occidental mountain range. The property comprises 4,950 hectares across five concessions and has significant infrastructure in place with direct access to utilities. A significant resource has been defined with over 225,000 metres of exploration drilling incurred to date. A number of key permits are already in place for underground mining and development, including permits for water use and discharge, general use of explosives, change use of soil, as well as underground mining and development which are permitted under an Environmental Impact Statement.

About Endeavour Silver

Endeavour is a mid-tier precious metals company with a strong commitment to sustainable and responsible mining practices. With operations in Mexico and the development of the new cornerstone mine in Jalisco state, the company aims to contribute positively to the mining industry and the communities in which it operates. In addition, Endeavour has a portfolio of exploration projects in Mexico, Chile and the United States to facilitate its goal to become a premier senior silver producer.

Quality Assurance / Quality Control

Drill core samples were shipped to ALS Limited in Zacatecas, Mexico for sample preparation and then for analysis at the ALS laboratory in North Vancouver and rock samples were shipped to SGS Lab in Durango, Mexico for sample preparation and analysis. The ALS Zacatecas, North Vancouver facilities and SGS lab are ISO 9001 and/or ISO/IEC 17025 certified. Silver and base metals were analyzed using a four-acid digestion with an ICP-AES / ICP-OES finish and gold was assayed by 30-gram fire assay with atomic absorption (“AA”) spectroscopy finish. Over limit analyses for silver were re-assayed by 30-gram fire assay and gravimetric finish and for lead and zinc re-assayed using an ore-grade four-acid digestion with ICP-AES / ICP-OES finish.

Control samples comprising certified reference samples, duplicates and blank samples were systematically inserted into the sample stream and analyzed as part of the Company’s quality assurance / quality control protocol.
