Discovery Reports Q3 2023 Financial Results and Update

TORONTO, Nov. 14, 2023 - Discovery Silver Corp. (TSX: DSV, OTCQX: DSVSF) ("Discovery" or the "Company") is pleased to announce its financial results for the third quarter ended September 30, 2023 ("Q3 2023"), and to provide a summary of key events for the quarter and subsequent to quarter-end. All figures are stated in Canadian dollars ("C$") unless otherwise noted. Discovery's flagship project is the 100%-owned Cordero silver project ("Cordero" or the "Project") located in Chihuahua State, Mexico.

Tony Makuch, CEO, states: "We made significant advances at Cordero during and subsequent to the third quarter of 2023. The submission of our Environmental Impact Statement ("Manifesto de Impacto Ambiental" or "MIA"), the principal permit required for the development of Cordero, represents a major milestone for the Company. The submission encapsulates detailed environmental and social baseline studies and is supported by third-party reviews from specialist environmental and engineering consultant firms. Meanwhile, our Feasibility Study ("FS") continues to progress well and remains on track for completion in Q1 2024. FS drilling wrapped up during the quarter with results highlighting the potential to extend the already long mine life at Cordero. We also reported strong results from our FS metallurgical test program demonstrating that higher silver recoveries of up to 7% into the precious metals concentrate are achievable at significantly reduced levels of reagent consumption. Concurrent to these positive developments, we made several key appointments to our board and management team which, in conjunction with our strong balance sheet with a current cash balance of approximately $65 million, provides us with an excellent platform to deliver our FS as well as advance Cordero through the permitting process."

HIGHLIGHTS FROM Q3 2023 & SUBSEQUENT EVENTS:

• Reported results from the FS metallurgical test program demonstrating higher silver recoveries of up to 7% to the precious metals concentrate at significantly lower reagent consumption.

¹TECHNICAL NOTES & REFERENCES:

Drill results: all drill 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. 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 is calculated as Ag(g/t) + 18.39 x Au(g/t) + 30.81 x Pb(%) + 36.54 x Zn(%). This calculation is based on metal prices of USD $22.00/oz Ag, $1,600/oz Au, $1.00/lb Pb, $1.20/lb Zn and life-of-mine average recovery assumptions from the 2023 Pre-Feasibility Study of 87% for Ag, 22% for Au, 86% for Pb and 85% for Zn.

Sample analysis and QA/QC Program
The true width of the veins is estimated to be approximately 70% of the drilled width. 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.
