Discovery Intersects 258 g/t AgEq over 66 m and 120 g/t AgEq over 143 m at Cordero
TORONTO, June 22, 2021 (GLOBE NEWSWIRE) -- Discovery Silver Corp. (TSX-V: DSV, OTCQX: DSVSF) (“Discovery” or the “Company”) is pleased to announce results from 12 diamond drill holes targeting bulk-tonnage mineralization at its flagship Cordero silver project (“Cordero” or “the Project”) located in Chihuahua State, Mexico. The holes are part of the recently completed Phase 1 drill program. The results from this program will be incorporated in a new resource estimate and PEA in the second half of the year. Phase 2 drilling is ongoing and is focused on resource definition and expansion.
Highlight intercepts include:
-
65.9 m averaging 258 g/t AgEq1 from 309.4 m (69 g/t Ag, 0.11 g/t Au, 0.7% Pb and 3.7% Zn) in hole C21-417
-
143.0 m averaging 120 g/t AgEq1 from 517.8 m (39 g/t Ag, 0.13 g/t Au, 0.4% Pb and 1.3% Zn) in hole C21-425
-
59.5 m averaging 153 g/t AgEq1 from 443.3 m (54 g/t Ag, 0.08 g/t Au, 0.9% Pb and 1.5% Zn) in hole C21-415
-
86.0 m averaging 108 g/t AgEq1 from 392.2 m (33 g/t Ag, 0.17 g/t Au, 0.3% Pb and 1.2% Zn) in hole C21-420
-
82.3 m averaging 136 g/t AgEq1 from 267.9 m (44 g/t Ag, 0.06 g/t Au, 0.7% Pb and 1.5% Zn) in hole C21-423
-
59.4 m averaging 171 g/t AgEq1 from 419.4 m (48 g/t Ag, 0.06 g/t Au, 1.0% Pb and 2.0% Zn) in hole C21-425
-
48.9 m averaging 159 g/t AgEq1 from 232.3 m (85 g/t Ag, 0.08 g/t Au, 0.6% Pb and 1.1% Zn) in hole C21-429
Taj Singh, President and CEO, states: “This current set of holes, drilled in areas where there were significant gaps in previous drilling, confirm the continuity of higher-grade mineralization at depth in the South Corridor. Excellent grades over broad widths were encountered on a consistent basis highlighting the potential for Cordero to emerge as one of the few multigenerational mines in the silver space. We look forward to compiling the final assay results from our Phase 1 drill program for incorporation in our resource update in Q3 2021 and preliminary economic assessment in Q4 2021.”
DRILL RESULTS:
Drill holes from this release confirm continuity of higher-grade bulk-tonnage mineralization at depth in the central part of the South Corridor. Mineralization is hosted within northeast trending domains that have been defined over a strike length of approximately 1.4 km and are open to the northeast. Hole C21-425 intercepted 143.0 m averaging 120 g/t AgEq1 from 517.8 m, confirming mineralization to a depth of 600 m, approximately 100 m below the pit bottom from the 2018 PEA.
Mineralization consists predominantly of galena, sphalerite and pyrite in disseminations, veinlets and stockworks hosted in breccia, rhyodacite and intervals of replacement mineralization in calcareous sediments. Higher-grade zones are typically flanked by medium and lower-grade mineralization pointing to the scaleability of the mineralized system at Cordero.

1All results in this news release are rounded. Assays are uncut and undiluted. Widths are drilled widths, not true widths, as a full interpretation of the actual orientation of mineralization is not complete. Intervals with stockwork mineralization were chosen based on a 25 g/t AgEq cutoff with no more than 10 m of dilution. Intervals with vein mineralization were based on a 100 g/t AgEq cutoff with no more than 1 m of dilution. AgEq calculations are used as the basis for total metal content calculations given Ag is the dominant metal constituent as a percentage of AgEq value in approximately 70% of the Company’s mineralized intercepts. AgEq calculations for reported drill results are based on USD $16.50/oz Ag, $1,350/oz Au, $0.85/lb Pb, $1.00/lb Zn. The calculations assume 100% metallurgical recovery and are indicative of gross in-situ metal value at the indicated metal prices. Refer to Technical Notes below for metallurgical recoveries assumed in the 2018 PEA completed on Cordero.
DRILL PROGRAM UPDATE:
Phase 1 drilling: The Company’s Phase 1 drill program concluded at the end of April. The data from the 75,000 m of new drilling (178 holes) completed in this program, along with 133,000 m of historic drilling (292 holes), will be used to support an updated resource (3Q 2021) and PEA (4Q 2021).
Phase 2 drilling: The Company has completed 11,000 m (31 holes) as part of its Phase 2 drill program which will be ongoing through the remainder of the year. Phase 2 drilling will be focused on three key areas: (1) upgrading inferred resources for inclusion in a prefeasibility study; (2) resource expansion of bulk-tonnage mineralization; and (3) testing of the width, grade and continuity of the extensive high-grade vein systems that transect the deposit. There are currently four drill rigs operating on site.
