Alpala MRE December 2018

A First Mover Advantage in Ecuador. Cornerstone has a diversified portfolio of gold, silver and copper projects in Ecuador and Chile, including a 15% interest in the exciting Cascabel copper-gold discovery in Ecuador financed through to a bankable feasibility study, and a joint venture with Ecuadorian state mining company ENAMI EP where we are exploring 9 highly prospective concessions in the vicinity of Cascabel. The potential geological endowment of Ecuador remains unknown due to under exploration but may be unparalleled. Cornerstone leverages its own exploration funding through joint venture and strategic partnerships, providing shareholders with potential for success at lower risk.
