Blende Silver Corp Provides Update for the Blende Zinc-Lead-Silver Property

(TheNewswire)

September 10 , 2025 – TheNewswire - Vancouver, Canada – Blende Silver Corp. (the “Company”)(TSX:BAG) announces an update for its  5,434 hectare Blendezinc-lead-silver property (the ”Property”) located within theTraditional Territory of the First Nation of Na-Cho Ny?k Dun and 65km northeast of Keno City, Yukon.

The Company completed its proposal for a Class 4 QuartzMining Land Use Approval (the “Application”) in January 2025. TheCompany has been actively engaged with regulatory authorities tofacilitate the approval process for the Class 4 Quartz Mining Permitwhich is essential for advancing exploration and development at theProperty. Proposed activities at the Property include the upgrade ofup to 5 km of existing trails, construction of up to 2 km of newtrail, one new heli-pad, a 1 km air strip, a new camp facility locatedabout 200 m up valley from the previously permitted camp, all insupport of a 25,000 m drill program which proposes up to 50 surfacediamond drill holes per year.

The Yukon Environmental and Socio-economic AssessmentBoard (YESAB) has extended its timeline for collecting public commentson the project until September 18, 2025. Stakeholders are encouragedto view the Application and participate in the assessment process bysubmitting their feedback through the YESAB Online Registry . Additionally, while the Class 4 Application is underreview, the Company is moving forward this week, with a smaller Class1 Exploration Notification which will initially see the installationof a smaller scale camp at the existing site to support a surfacedrill program over a period of less than 250 person days percamp.

The Company’s director, Andrew H Rees, stated “Weare excited to continue exploration on the Blende Property which, in1995, was reported to be the largest strata-bound, carbonate-hosted,zinc-lead deposit in the Yukon as described in Economic Geology, Vol.90,1995 ”.

The Property covers a Proterozoic-aged carbonate-hostedmassive sulphide deposit with characteristics of both Irish-type andclastic-dominated zinc-lead deposits. The mineralization is hostedwithin Lower Proterozoic Gillespie Group dolomite, forming a >6 kmmineralized corridor on the southern edge of the Mackenzie Platform.An NI 43-101 compliant Mineral Resource Estimate was completed for theProperty by Moose Mountain Technical Services, Effective Date March15, 2021 reporting an Indicated Mineral Resource of 4.6 million tonnesgrading 1.82% Zn, 1.63% Pb and 30.3 g/t Ag (187 million pounds ofzinc, 167 million pounds of lead and 4.5 million ounces of silver),along with an Inferred Mineral Resource of 42.2 million tonnes grading1.83% Zn, 1.62% Pb and 27.5 g/t Ag (1.7 billion pounds of zinc, 1.5billion pounds of lead and 37.3 million ounces of silver) (see Company website and SEDAR+ ).

Table 1. Mineral Resource Estimate for the BlendeProject (Effective date: March 15, 2021)

Notes to Table:

1. The Mineral Resource Estimate has been prepared bySue Bird, P.Eng., an independent Qualified Person.

2. Resources are reported using the 2014 CIM DefinitionStandards and were estimated using the 2019 CIM Best PracticesGuidelines.

3. Mineral Resources that are not Mineral Reserves donot have demonstrated economic viability.

4. The Mineral Resource has been confined by a“reasonable prospects of eventual economic extraction” pit usingthe following assumptions: US $1.3/lb Zn, US $1.0/lb Pb and US$26/ozAg at a currency exchange rate of 0.77 US$ per ; Recoveries of 70%Zn, 85% Pb and 90% Ag, a 3% NSR royalty and Payable of 88% payable Zn,83% payable Pb, 73% payable Ag.

5. The resulting ZnEq is: ZnEq =Zn% + (Pb% ? $1.0 ? 0.85 ? 0.95)/(Zn% ? $1.3 ? 0.70 ?0.85) + Ag gpt/31.1034 ? $26 ? 0.90 ? 0.80) / (Zn% ? 1.3 ?0.70 ? 0.85 ? 22.0462)

6. The specific gravity of the deposit has beendetermined by correlation with Zn and Pb grades. sg=(Zn%+Pb%)*0.015+2.8

7. Pit slope angles are assumed at 45º

8. Numbers may not add due to rounding.
