IMPACT Silver Intersects 10.38% Zinc over 3.94m Including 20.95% Zinc over 1.70m at the Plomosas Mine

Vancouver, British Columbia--(Newsfile Corp. - July 7, 2025) - IMPACT Silver Corp. (TSXV: IPT) (OTCQB: ISVLF) (FSE: IKL) ("IMPACT" or the "Company") is pleased to announce further results from an ongoing underground drill program in the Juarez Zone at its Plomosas zinc (lead-silver) Mine in northern Mexico.

JUAREZ ZONE DRILLING

New drill intersections on the down dip projection of the Juarez Zone of the Plomosas Mine are as follows:

TABLE 1: NEW JUAREZ ZONE DRILL RESULTS - PLOMOSAS MINE

True width estimates are interpreted from current geological models. The Juarez Zone lies stratigraphically below the Mina Vieja (Tres Amigos Mine) horizon at the Plomosas Mine and has a separate access adit (see Figures 2 & 3). All these Juarez Zone drill intersections lie outside the JORC mineral resource blocks published by the previous operator (see IMPACT news release dated April 3, 2023 for details). Juarez Zone mineralization remains open for exploration in all directions and drilling is continuing.

CEO STATEMENT

President and CEO Frederick Davidson commented, "We are happy to see ongoing great drill results from the Juarez Zone at the Plomosas Mine. The location of these drill holes close to our underground mining infrastructure allows us to rapidly expand our mining operations into these areas. We continue to drill from surface and underground with the aim to expand mineral resources on several zones at Plomosas."

PLOMOSAS MINE GEOLOGY AND MINERALIZATION

The Plomosas mine, a historic high-grade zinc producer in northern Mexico (Figure 1), was acquired in 2023 by the Company. Recent drill programs have been undertaken in the Tres Amigos area on extensions of active mine areas and nearby in the Juarez Zone and Santo Domingo Zone (results pending). Drilling is continuing. Mineralization at the Plomosas mine occurs as zinc-rich Carbonate Replacement zones along certain horizons of the local sedimentary rock sequence. Two main mineralized horizons have provided the bulk of historic production, the Mina Vieja (Tres Amigos) marble and the Juarez limestone, where structural ground preparation along these two units favored concentrations of zinc, lead, and silver (see Figure 3).

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 oz 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 18 years, IMPACT has developed multiple exploration zones into commercial production and has produced over 13 million ounces of silver, generating revenue of more than $284 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. In late 2023, the Company restarted mining operations and is ramping up production toward design capacity levels. 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 belt as some of the largest carbonate replacement deposits in the world.

Quality Control/Quality Assurance

Drill core was NTW size (5.71 cm diameter). Half core samples were collected with a rock saw and tagged for identification. All samples were securely stored at the Plomosas Mine until shipment. A total of 5% certified assay standards and 5% blanks were inserted into every sample shipment as a quality control measure. All samples were shipped to the ALS preparation laboratory in Chihuahua, Mexico, where they were fine crushed (70% passing a 2 mm screen), pulverized (85% passing a 75 micron screen) and pulp split separated for assay. These pulps were shipped to the ALS laboratory in North Vancouver, Canada, where a 10 gram split was aqua regia digested and then analyzed for 36 elements including zinc, lead and silver by ICP-AES spectrometry (ALS code ME-ICP41). Assays for base metals >1% used an overlimit ICP-AES method (ALS code OG46). ALS is an independent, international ISO/IEC 17025 accredited laboratory.

Qualified Person and NI 43-101 Disclosure

Silvia Kohler, P.Geo., a Senior Geologist employed by IMPACT Silver Corp. and a "Qualified Person" within the meaning of NI-43101, has approved the technical information contained in this news release.

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. Such statements include, but are not limited to, statements regarding interpretation of drill results, activity at the projects and estimated timing thereof, the potential for defining and extending the known mineralization, exploration potential on the properties, and plans for drilling and future operations at the Company's projects or plans for financing.

Such forward-looking information involves known and unknown risks and assumptions, including with respect to, without limitation, exploration and development risks, expenditure and financing requirements, title matters, operating hazards, extreme weather events, criminal activity, metal prices, political and economic factors, community relations, competitive factors, general economic conditions, relationships with vendors and strategic partners, governmental regulation and supervision, seasonality, technological change, industry practices, pandemics 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 or beliefs, opinions, projections or other factors, 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 at Zacualpan 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 mineral resources or reserve estimates, preliminary economic assessments or feasibility studies, and historically such projects have increased uncertainty and risk of failure.
