The PEA is based on an estimated Measured and Indicated Resource containing 4 M oz. gold equivalent³. For further details please refer to the footnotes at the end of this news release.
• Proven management team: Extensive experience in all critical mining and exploration disciplines with demonstrated capabilities in financing, acquiring, developing and operating mines and a proven track record of exploration successes.
• Enhanced market presence: The larger merged company is expected to appeal to a broader institutional shareholder base and improve share trading liquidity.
• Compelling value proposition: Significant leverage among junior Mexico explorer's equities and attractive relative valuation based on net asset value.

Peter J. Hawley, President and CEO of Defiance, stated "We are extremely pleased with this transformational transaction that represents excellent value for our shareholders. Post-merger, Defiance will boast both the significant exploration potential and initial deposit at the high-grade and wide-vein San Acacio silver project as well as the foundational 4 M oz. gold-equivalent resource³ Tepal gold-copper project. With a best-in-class Board of Directors, we look forward to aggressively exploring San Acacio as well as seeking other accretive acquisition opportunities."

Dunham Craig, President and CEO of ValOro, said "Combining ValOro with Defiance presents an opportunity to build a premier exploration company focused on Mexico, driven by an experienced management team and the opportunity to significantly enhance the long term growth potential of the Tepal gold-copper project. With a 2017 Preliminary Economic Assessment that produced positive economic results coupled with our 2017 and 2018 exploration work in preparation for a drill program to potentially expand the resource and test new targets, this transaction provides further value accretion by coupling our asset with the exploration potential at the San Acacio Silver deposit, further providing value accretion for ValOro and our shareholders."
