Discovery appoints Ausenco as lead consultant for Cordero
TORONTO, May 12, 2021 (GLOBE NEWSWIRE) – Discovery Silver Corp. (TSX-V: DSV, OTCQX: DSVSF) (“Discovery” or the “Company”) is pleased to provide a project update and to announce the project study team for its preliminary economic study ( “PEA” or “Study”) on the Cordero Company’s flagship project (“Cordero” or “the Project”) located in the State of Chihuahua, Mexico. The PEA will be led by Ausenco Engineering Canada Inc. (“Ausenco”) and is scheduled for completion in 4Q 2021 and will be based on an updated resource estimate scheduled for completion in 3Q 2021.
Taj Singh, President and CEO, said: “The goal of our PEA is to make Cordero one of the most productive and longest-running primary silver mines in the world, with costs in the lower half of the industry’s cost curve. The study will be supported by a comprehensive drilling and metallurgy data set and will be undertaken by a leading Ausenco-led project team with input from specialists from all key mining disciplines. As study work progresses, we will continue to remain focused on adding value through drilling with our recently launched Phase 2 drilling program.
Phase 1 drilling: The Company’s Phase 1 drilling program was completed at the end of April. Data from the 75,000 m of drilling completed under this program will be used to support the resource update on which the PEA will be based.
Phase 2 drilling: The four drilling rigs currently operating at the site will continue uninterrupted with Phase 2 drilling which will focus on three key areas: (1) upgrading inferred resources to be indicated for inclusion in a pre-feasibility study; (2) expansion of large tonnage mineralization resources; and (3) testing the width, grade and continuity of the large high-grade vein systems that transect the deposit.
Updating resources: An updated resource estimate is expected to be completed in 3Q 2021. The resource estimate will be based on an updated geological model of the deposit which includes relining of 110,000m of historic drilling plus 75,000m of drilling. of the phase 1 drilling program. The resource model will use estimation domains based on structure and lithology. Previous resource estimates did not take these constraints into account.
Metallurgical tests: A comprehensive metallurgical testing program with samples based on both lithology and mining phases is underway with results expected in 3Q 2021. Testing is being conducted by Blue Coast Research Ltd. (“Blue Coast”) under the supervision of Libertas Metallurgy Ltd. (“Libertas”) And Ausenco. The current program will extend to previous metallurgical testing programs conducted by ALS Ltd. in 2013 and METCON Research Inc. in 2011.
Mining: The Company has already worked with AGP Mining Consultants Inc. (“AGP Mining”) to complete the preliminary pit optimization work to assist with drilling targeting. Preliminary mine planning work was also completed to assess the impact on project economics of different mining rates, mill throughput rates, and cut-off and storage strategies. The objective of this work is to optimize the net present value (“NPV”) and the efficiency of the capital (ratio of the initial capital expenditure to the NPV).
Geotechnics / Hydrology / Hydrogeology: Knight Piésold and Co. (USA) (“Knight Piésold”) carried out a site visit to Cordero in March 2021. The site visit included an examination of the drill core to assess the stability of the pit wall, an assessment potential tailings and waste storage sites and a preliminary review of Cordero’s hydrogeological regime. Dedicated open pit geotechnical drilling is scheduled to begin this month and will be used to generate pit slope assumptions for the PEA.
ESG: An environmental benchmark study managed by CIMA Consultores (“CIMA”) began in the first quarter of 2021 and will continue throughout the year. An office social baseline assessment has already been carried out by Vinfidem Consultoria (“Vinfidem”) and follow-up field work is expected to start later this quarter. The main findings of the two sets of work will be included in the PEA. The ESG work will be completed by the company’s first ESG report, which is scheduled for publication in Q3 2021. The report will describe the company’s ESG approach with regard to strategy, planning and risk management and will be developed in collaboration with Stratos Inc. (“Stratos”).
PEA PROJECT TEAM
The PEA project team will be led by Ausenco, an industry leader in designing and building cost-effective processes. Ausenco is a global company providing innovative value-added consultancy studies, project delivery, asset operations and maintenance solutions in the minerals and metals industry with recent and relevant experience in studies, project construction (“EPC”) and construction management (“EPCM”) on projects in the Americas. Ausenco has significant experience in Mexico, including recently leading the feasibility study (and future EPC) for the Las Chispas project of SilverCrest Metals Inc. Ausenco also has recent experience with sizeable processing plants and / or recovery schemes similar to what is expected at Cordero, including the Arctic project of Trilogy Metals Inc. in Alaska (feasibility study), the Constancia mine of Hudbay Minerals Inc. in Peru (EPCM), The Mina Justa mine of Minsur SA in Peru (feasibility study and EPCM), the Mantoverde project of Mantos Copper SA in Chile (EPC), the Blackwater project (EPC) of Artemis Gold Inc. in Canada and the Magino project of Argonaut Gold Inc. ( EPC) in Canada.

OVERVIEW OF PEA
Goal of the study: The overarching goal is to provide a technically sound study supported by a comprehensive data set and endorsed by leading independent consultants with third party peer review. The company’s goal for the study is to describe one of the largest primary silver production operations in the industry with development investments and manageable operating costs in the lower half of the price curve. industry costs.
Processing plant: The study will include phased expansions of the processing facility to reduce initial capital expenditure and payback period. Production trade-off studies are underway, but based on preliminary results, the initial throughput of the plant is expected to be between 10,000 and 20,000 tonnes per day (“tpd”) and the plant throughput increased. should be between 20,000 and 40,000 t / d. interval.
Mine plan: The mine schedule will include a high cut-off grade early in mine life and efficient use of storage to accelerate the payback period and maximize NPV at set throughput rates. A trade-off study comparing the use of contract mining to owner mining is underway.
