Highlight intercepts include:
- 2 m averaging 165 g/t AgEq1 from 312.4 m (65 g/t Ag, 0.05 g/t Au, 1.2% Pb and 1.3% Zn) including 26.1 m averaging 263 g/t AgEq1 (109 g/t Ag, 0.06 g/t Au, 2.0% Pb, 1.9% Zn) in hole C20-405
- 0 m averaging 110 g/t AgEq1 from 137.1 m (37 g/t Ag, 0.04 g/t Au, 0.8% Pb and 1.0% Zn) and 51.8 m averaging 184 g/t AgEq1 (65 g/t Ag, 0.05 g/t Au, 1.6% Pb, 1.4% Zn) in hole C21-414
- 4 m averaging 279 g/t AgEq1 from 382.0 m (78 g/t Ag, 0.08 g/t Au, 1.3% Pb and 3.6% Zn) in hole C20-407
DRILL RESULTS:
Drill holes from this release build further higher-grade bulk-tonnage continuity in the South Corridor within northeast trending domains. These domains have been defined over a strike length of approximately 1.4 km and are open to the northeast and have been drilled to a depth of 500 m and remain open below this. Higher-grade zones of mineralization are typically flanked by medium and lower-grade mineralization pointing to the scaleability of the mineralized system at Cordero. Mineralization typically consists of galena, sphalerite and pyrite in disseminations, veinlets and stockworks predominately hosted in breccia, rhyodacite and intervals of replacement mineralization in calcareous sediments.
Drill hole locations are shown in Figure 1 (see links below) and detailed drill highlights from the 13 holes in this release are provided in the table below.
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.
PHASE 1 DRILL PROGRAM UPDATE:
The Company has completed 70,100 m (171 holes) as part of its expanded Phase 1 drill program that started in September 2019 and is scheduled for completion at the end of this month. Assays from 43 holes are pending. Data from Phase 1 drilling will be used to support the bulk-tonnage resource update and PEA scheduled for the second half of the year.
The four drill rigs currently operating on site will continue uninterrupted with Phase 2 drilling. Phase 2 drilling will be focused on three key areas: (1) upgrading inferred resources to indicated for inclusion in a prefeasibility study on Cordero; (2) resource expansion of bulk-tonnage mineralization; and (3) testing of the width, grade and continuity of extensive high-grade vein systems that transect the deposit.

About Discovery
Discovery’s flagship project is its 100%-owned Cordero project, one of the few silver projects globally that offers margin, size and scaleability. The project is located in a prolific mining belt in Chihuahua State, Mexico, and is supported by an industry leading balance sheet with over C$90 million of cash allocated 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.

Sample analysis and QA/QC Program
True widths of reported drill intercepts have not been determined. Assays are uncut except where indicated. All core assays are from HQ drill core unless stated otherwise. Drill core is logged and sampled in a secure core storage facility located at the project site 40km north of the city of Parral. Core samples from the program are cut in half, using a diamond cutting saw, and are sent to ALS Geochemistry-Mexico for preparation in Chihuahua City, Mexico, and subsequently pulps are sent to ALS Vancouver, Canada, which is an accredited mineral analysis laboratory, for analysis. All samples are prepared using a method whereby the entire sample is crushed to 70% passing -2mm, a split of 250g is taken and pulverized to better than 85% passing 75 microns. Samples are analyzed for gold using standard Fire Assay-AAS techniques (Au-AA24) from a 50g pulp. Over limits are analyzed by fire assay and gravimetric finish. Samples are also analyzed using thirty three-element inductively coupled plasma method (“ME-ICP61”). Over limit sample values are re-assayed for: (1) values of zinc > 1%; (2) values of lead > 1%; and (3) values of silver > 100 g/t. Samples are re-assayed using the ME-OG62 (high-grade material ICP-AES) analytical package. For values of silver greater than 1,500 g/t, samples are re-assayed using the Ag-CON01 analytical method, a standard 30 g fire assay with gravimetric finish. Certified standards and blanks are routinely inserted into all sample shipments to ensure integrity of the assay process. Selected samples are chosen for duplicate assay from the coarse reject and pulps of the original sample. No QAQC issues were noted with the results reported herein.
