*Zinc Equivalent (ZnEq) is calculated using recent metal prices of US$1.47/lb Zn, US$0.92/lb Pb and US$50.44/oz Ag, and metal recoveries of 90.5% Zn, 76.5% Pb, and 85.0% Ag based on recent Plomosas production mill recoveries. Metal equivalence values allow for easier comparison of mineral zones with multiple metals reporting.

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.

CEO STATEMENT

President and CEO Frederick Davidson commented, "We are pleased with these new high-grade drill intersections on extensions of the Juarez Zone adding mineralization for ongoing mining. The location of these intersections on extensions of our underground mining infrastructure allows us to readily expand our mining operations into these areas. We now have two drills testing extensions of near mine targets and have begun to carry out exploration drilling on other targets along the under-explored six kilometre CRD trend."

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 on extensions of active mine areas in the Tres Amigos Zone, the Juarez Zone and Santo Domingo Zone (see Figure 2). Mineralization at the Plomosas mine occurs as zinc-rich Carbonate Replacement zones in three bedrock units - the Mina Vieja marble (Tres Amigos Zone), the Juarez limestone (Juarez Zone) and in carbonate layers within the Cuesta Shale (Santo Domingo Zone) - where structural ground preparation along these units accommodated 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 19 years, IMPACT has developed multiple exploration zones into commercial production and has produced over 13.5 million ounces of silver, generating revenue of more than $298 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 ramped 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 (see Figure 1).

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.
