Discovery Silver Corp. (TSX-V: DSV, OTCQX: DSVSF) is pleased to announce results from 21 diamond drill holes targeting bulk-tonnage mineralization in the North Corridor at its flagship Cordero silver project located in Chihuahua State, Mexico. The results from this release will be incorporated in the new resource estimate scheduled for completion later this quarter and PEA in 4Q 2021.
Highlight intercepts include:
Taj Singh, President and CEO, states: “Our drill results continue to reinforce the broad widths and excellent grades that characterize large areas of the Cordero deposit. Drilling in the NE Extension was successful in extending the strike length of high-grade mineralization by approximately 100 m. The five best intercepts within this zone, including four intercepts from this release, have returned an average interval of 109 m at 212 g/t AgEq. Today’s results, along with the final assay results from our Phase 1 drill program will be incorporated in our upcoming resource estimate due to be released later this quarter.”
Drilling in the NE Extension zone was successful in expanding the high-grade zone intercepted in C20-319, which returned 168.8 m of 207 g/t AgEq1 from 140.0 m (see May 7, 2020, press release), by approximately 100 m along strike. Holes in this release drilled to the northeast of C20-319 intercepted 132.6m of 260 g/t AgEq1 and 77.1 m of 190 g/t AgEq1 (C21-479), 86.2 m of 192 AgEq1 (C21-476) and 81.4 m of 184 g/t AgEq1 (C21-496). Follow up drilling targeting the expansion of this zone to the northeast of C21-496 will be completed during the Phase 2 drill program.
Drilling in the SW Extension zone was successful in confirming continuity of mineralization within the high-grade bulk-tonnage domain in areas where there were gaps in previous drilling. Highlight intercepts include 102.7 m of 96 g/t AgEq1 (C21-486) and 55.7 m of 76 g/t AgEq1 (C21-490). Drilling in the Far NE, an area of the deposit that has seen little previous drilling, was targeting the potential expansion of the high-grade bulk-tonnage domain to the northeast. Assay results reported a number of shallow lower grade intercepts in combination with encouraging intercepts including 94.3 m of 93 g/t AgEq1 (C21-461), 42.8 m of 92 g/t AgEq1 (C21-448) and 37.0 m of 98 g/t AgEq1 (C21-453). These results will be reviewed in conjunction with the updated resource model prior to further drilling in this part of the deposit.

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. As a guideline, intervals with disseminated 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). The final assay results from Phase 1 drilling (14 holes) are expected to be released later this month. Phase 2 assay results that have been received whilst awaiting final assays from Phase 1 will also be used to support the updated resource and PEA.
Phase 2 drilling: The Company has completed 21,600 m (56 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.

Discovery’s flagship project is its 100%-owned Cordero project, one of the few silver projects globally that offers margin, size and scaleability. Cordero is located close to infrastructure in a prolific mining belt in Chihuahua State, Mexico, and is supported by an industry leading balance sheet with approximately C$85 million available for aggressive exploration, resource expansion and future development. Discovery was a recipient of the 2020 TSX Venture 50 award and the 2021 OTCQX Best 50 award.
