Public Offering:

The Company announced on April 19, 2023, that it closed its previously announced "marketed" public offering of common shares of the Company for aggregate gross proceeds of approximately C$51.75 million (the "Offering"). The Offering was conducted by a syndicate of agents co-led by Clarus Securities Inc. and Cormark Securities Inc., and including BMO Nesbitt Burns Inc., Eight Capital, and PI Financial Corp. (collectively, the "Agents"), and consisted of the sale of 43,125,000 common shares of the Company which included the full exercise of the Agents' option at a price of C$1.20 per Share.

The Company intends to use the net proceeds from the Offering to fund the continued advancement and de-risking of the Cordero Project and for working capital and general corporate purposes.

Further details can be found in the news releases dated April 12, 2023, and April 19, 2023.

Key De-Risking Items:

The Company has made excellent progress so far this year on the critical de-risking items for Cordero - surface rights, water, power, permitting and the Feasibility Study - in the systematic advancement of Cordero towards a construction decision. The Company recently secured the surface rights that correspond with the planned open pit and key infrastructure locations at Cordero as well as a significant volume of water rights. Discovery also recently engaged M3 Engineering & Technology Corp to complete a technical review of the scope and cost to source water from existing water treatment plants in the region.

An impact assessment study and power installation study by Mexican electrical infrastructure authority CENACE were delivered earlier this year, with confirmation that there is sufficient capacity in the existing power grid to supply the Project with power for operations at peak throughput levels. Standard upgrades of the Camargo II substation will be required as well as the installation of a 74-kilometre powerline along the existing power corridor. The Company will also be evaluating the option to use renewable energy sources at site to supplement grid power.

The Company is set to initiate the permitting process later this month with the submission of its MIA to SEMARNAT. The MIA is one of the principal permits required for the development of Cordero and encapsulates extensive social and environmental work programs completed by the Company's team in Mexico since 2020 in parallel with multiple reviews by third-party consultants. Cordero benefits from being located on private land in an area of Mexico (Chihuahua State) where mining has a long history and is a key economic contributor.

For further details on the progress on key de-risking items noted above refer to our news release dated June 22, 2023.

Feasibility Study Drilling:

The Company has drilled over 52,000 m (164 holes) as part of its FS drill program (since the data cut-off for the PFS study). This includes approximately 35,000 m of reserve definition and expansion drilling, 7,000 m of condemnation drilling and 10,000 m of engineering drilling (hydrogeology and geotechnical). Engineering drilling will be ongoing through the remainder of the year along with the property-wide drill program which commenced last month.

Reserve Expansion Drilling - the reserve expansion and definition component of our Feasibility Study drill program is now complete. Highlight intercepts from this drilling include:

• 41 m averaging 197 g/t AgEq¹ (63 g/t Ag, 0.09 g/t Au, 1.2% Pb and 2.7% Zn) from 386 m and 8 m averaging 416 g/t AgEq¹ (195 g/t Ag, 0.23 g/t Au, 2.2% Pb and 4.1% Zn) from 79 m in the core of the South Corridor in hole C22-688.
• 37 m averaging 139 g/t AgEq¹ (58 g/t Ag, 0.05 g/t Au, 0.8% Pb and 1.5% Zn) from 236 m and 104 m averaging 86 g/t AgEq¹ (37 g/t Ag, 0.04 g/t Au, 0.3% Pb and 1.1% Zn) from 91 m in hole C22-705; these intervals were in the southern portion of the South Corridor within the reserves pit.
• 52 m averaging 105 g/t AgEq¹ (51 g/t Ag, 0.19 g/t Au, 0.6% Pb and 0.9% Zn) from 102 m and 37 m averaging 171 g/t AgEq¹ (79 g/t Ag, 0.09 g/t Au, 1.1% Pb and 1.5% Zn) from 276 m in hole C22-722 in the southwest of the South Corridor.
• 15 m averaging 479 g/t AgEq¹ (278 g/t Ag, 0.08 g/t Au, 3.1% Pb and 2.9% Zn) from 145 m in hole C22-713 also in the southwest of the South Corridor.
• 39 m averaging 134 g/t AgEq¹ (104 g/t Ag, 0.17 g/t Au, 0.5% Pb and 0.3% Zn) from 46 m in hole C22-728 in the southwest of the North Corridor.
  

These positive drill results demonstrate the potential to expand reserves through the conversion of waste to ore within the reserves pit and through the expansion at depth of the reserves pit.

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.
