Bradford Cooke, CEO of Endeavour, stated, “Our brownfields exploration programs were successful last year in replacing our reserves and resources. Reserves and resources increased significantly at Guanacevi due to our successful exploration of the El Curso property, which separates and adjoins our current Milache and historic Porvenir Cuatro orebodies. With additional drilling, these have the potential to become one large orebody, on the scale of our original Porvenir Norte discovery which we mined for 15 years.”
“At Bolanitos and El Compas, reserves and resources declined somewhat, however we continued to make new discoveries in each district. Bolanitos benefited from the delineation of the Melladito discovery and El Compas benefited from the discovery of new silver-gold-lead-zinc resources on the Calicanto property near the plant. We are currently evaluating the economic potential of these new resources at El Compas. After conducting minimal exploration drilling at Terronera and none at Parral in 2020, we have returned our focus to expanding resources at these two projects in 2021.”
Mineral Reserve and Resource Discussion
Proven and Probable Mineral Reserves for silver increased year on year by 11% to 48.6 million oz, while Proven and Probable Mineral Reserves for gold remained relatively unchanged to 472,000 oz. Silver equivalent Mineral Reserves increased 5% year on year to 86.3 million oz (at a silver to gold ratio of 80:1), due mainly to delineating new reserves and resources at Guanacevi.
Measured and Indicated Mineral Resources for silver decreased by 11% to 25.9 million oz and Measured and Indicated Mineral Resources for gold decreased by 2% to 222,500 oz gold. Silver equivalent Measured and Indicated Mineral Resources declined 8% to 43.7 million oz due mainly to reserve and resource reductions at Bolanitos and Compas.
Inferred Mineral Resources for silver increased by 6% to 64.4 million oz and Inferred Mineral Resources for gold decreased by 1% to 283,800 oz. Silver equivalent Inferred Mineral Resources rose 4% to 87.1 million oz due mainly to gains at Guanacevi and El Compas.
Dale Mah, P.Geo., Vice President Corporate Development of Endeavour, is the Qualified Person who reviewed and approved this news release and the technical information contained in these Mineral Reserve and Resource Estimates. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results.
