Guerrero Exploration Inc. (TSX: V.GEX) was up 4.4% to 12 cents. The stock is reacting to news that the junior explorer had received the title certificates for its 100% owned Cibola and Coatepec concessions, and expects the Olinala concession to be granted in the coming months. Collectively, the three concessions overlap a combined surface area of 137,546 hectares in the Mixteca Terrane of eastern Guerrero State, Mexico. The company expects that exploration of these concessions will start in the fall of 2013.
