IMPACT SILVER ANNOUNCES APPOINTMENT OF CHIEF

FINANCIAL OFFICER

Vancouver, B.C., December 12, 2025. IMPACT Silver Corp. (TSXV:IPT) (OTCQB: ISVLF) (FSE: IKL)

(“IMPACT” or the “Company”) is pleased to announce the appointment of Fernando Montoya as the

Company’s Chief Financial OƯicer, eƯective immediately.

Fernando Montoya, LL.B., CPA, brings a unique combination of corporate finance, accounting, legal,

and operational support expertise developed over 25 years, with a strong emphasis on cross-border

financial management and regulatory compliance between Mexico and Canada. He has advised

multiple Canadian-listed mining companies with producing assets in Mexico, applying deep

knowledge of IFRS financial reporting, internal control frameworks, treasury functions, and cross-

jurisdictional tax and legal structuring. Fernando’s background includes senior financial and

administrative roles within multinational mining groups, as well as nearly a decade with KPMG—

ultimately heading the Chihuahua o Ưice—where he led audit and advisory engagements for

international clients across diverse reporting frameworks. His dual qualifications as a licensed

lawyer and CPA, together with extensive experience supporting operational roles and decision-

making at active mine sites, enable a fully integrated approach to cross-border compliance, fiscal

strategy, and operational oversight for the Company’s producing mines and Canadian corporate

platform.

Jerry Huang will continue with the Company as Vice President, Finance where he will focus on

expanding relationships within the investment community, advancing M&A initiatives, and driving

opportunities to enhance shareholder value. Over his tenure as CFO, Jerry has demonstrated his

fundraising capabilities and has established solid relationships with shareholders, investors,

institutions, finance partners and the broader mining and investment communities. As IMPACT grows

organically and through acquisitions, divestitures, and potential joint ventures, Mr. Huang will

concentrate on strengthening IMPACT’s market value.

Fred Davidson, CEO of the Company added: “We welcome the addition of Mr. Montoya to our

management team at IMPACT. Mr. Montoya has acted as a financial and administrative consultant

to the Company over the past few years, working well with our operating group and demonstrating

strong financial leadership and direction. Combined with his legal and mining experience Mr.

Montoya will be actively involved in guiding the growth of the Company in Mexico and Canada in the

future. ”

ABOUT IMPACT SILVER

IMPACT Silver Corp. (TSXV: IPT) is a successful producer-explorer with two mining projects in Mexico.

 Royal Mines of Zacualpan Silver-Gold District: IMPACT owns 100% of the 211 km2 Zacualpan project

in central Mexico where four producing underground silver mines and one open pit mine feed the

central 500 tpd Guadalupe processing plant. To the south, the Capire Project includes a 200 tpd

processing pilot plant adjacent to an open pit silver mine with an NI 43-101 inferred mineral resource

of over 4.5 million ounces silver, 48 million lbs zinc and 21 million lbs lead (see IMPACT news release

dated January 18, 2016, for details and QP statement). Company engineers are reviewing Capire for a

potential restart of operations to leverage improving commodity prices. Over the past 19 years, IMPACT

has developed multiple exploration zones into commercial production and has produced over 13.7

million ounces of silver, generating revenue of more than $307 million, with no long-term debt.

 Plomosas Zinc-Lead-Silver District: Plomosas is a high-grade zinc producer in northern Mexico with

exceptional exploration upside potential. The Company recently restarted mining operations and is

ramping up production. Exploration potential at Plomosas is exceptional along the 6 km long structure.

This is in addition to other exploration targets on the 3,019-hectare property including untested

copper-gold targets with indications of high-grade material at surface. Regionally, Plomosas lies in the

same mineral belt as some of the largest carbonate replacement deposits in the world.

George Gorzynski, PEng, a director of the Company, is a qualified person within the meaning of NI 43-101 and

has approved the technical information contained in this news release.

Forward-Looking and Cautionary Statements

This IMPACT News Release may contain certain “forward-looking” statements and information relating to

IMPACT that is based on the beliefs of IMPACT management, as well as assumptions made by and information

currently available to IMPACT management. Forward-looking information is often, but not always, identified by

the use of words such as “seek” , “anticipate” , “plan” , “continue” , “planned” , “expect” , “project” , “predict” ,

“potential” , “targeting” , “intends” , “believe” , “potential” , and similar expressions, or describes a “goal” , or

variation of such words and phrases or state that certain actions, events or results “may” , “should” , “could” ,

“would” , “might” or “will” be taken, occur or be achieved.

economic conditions, relationships with vendors and strategic partners, governmental regulation and

supervision, criminal activity, seasonality, technological change, industry practices, and one-time events.

Should any one or more risks or uncertainties materialize or change, or should any underlying assumptions

prove incorrect, actual results and forward-looking statements may vary materially from those described

herein. IMPACT does not assume the obligation to update any forward-looking statement except as required by

law.

The Company’s decision to place a mine into production, expand a mine, make other production related

decisions or otherwise carry out mining and processing operations, is largely based on internal non-public

Company data and reports based on exploration, development and mining work by the Company’s geologists

and engineers. The results of this work are evident in the discovery and building of multiple mines for the

Company and in the track record of mineral production and financial returns of the Company since 2006. Under

NI 43-101 the Company is required to disclose that it has not based its production decisions on NI 43-101

compliant mineral resource or reserve estimates, preliminary economic assessments or feasibility studies,

and historically such projects have increased uncertainty and risk of failure.
