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 13.5 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. 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.

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.
