The Pennsylvania-based company, which plans to shift its headquarters to Tuscon, Arizona, will soon begin exploration and development of the new mines.
The company will focus on gold and silver though one of its new properties is a polymethallic project.
Entertainment Games director Pedro Villagran-Garcia said, "We have a great deal of experience in building and managing exploration stage mining companies. Mexico is supportive of mining, making it a very exciting industry to be in."
