Guerrero Exploration and its JV partner first initiated a field exploration program at the Cerro Azul property in February 2011. The program consisted of prospecting, geochemical sampling and induced polarization/resistivity geophysics. Seven anomalies were identified on the Property: Cerro Azul, Las Trojas, El Pedrillo, La Palma, Las Minillas, Loma Coyote and Llano Grande (GEX News Release 26 May 2011). Of these, three have been selected for drill testing: Las Trojas, Las Minillas and Loma Coyote. Collectively, these three anomalies define a northwest trending zone 5000 meters long and 600 meters wide hosted in Cretaceous sedimentary rocks on the southern portion of the concession. Mineralization consists mainly of chalcocite in veinlets and disseminations with minor disseminated pyrite. On surface, this is oxidized to malachite, azurite, chrysocolla, jarosite, goethite and hematite.
