of two and one-half (2.5) years to vote the Consideration Shares in accordance with Mexican Gold

management instruction.

Tatatila is a gold-copper skarn district located in Veracruz State that Chesapeake identified in 2007.

Tatatila surrounds Mexican Gold's Las Minas Project, which has a reported NI 43-101 Mineral Resource
