VANCOUVER, BRITISH COLUMBIA, Jun 19, 2013 (Marketwired via COMTEX) — Guerrero Exploration Inc. (“Guerrero” or the “Corporation”) (tsx venture:GEX)(frankfurt:2GU) provides the following update on development of its Cerro Azul property located in Guerrero, Mexico:

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.

Las Trojas is defined by co-incident chargeability and resistivity highs in an area 800 m long by 400 meters wide. Half of the 40 soil samples in this area contain more than 56 ppm Cu, and the highest copper-in-soil result is 11,800 ppm Cu. Rock samples from two historic mine workings in the area contain up to 37,000 ppm Cu and 43.4 ppm Ag. Four holes totaling 900 meters of drilling are planned to test Las Trojas.

La Minillas is 700 meters northwest of Las Trojas and is also defined by co-incident chargeability and resistivity highs in an area of anomalous copper geochemistry. The anomaly area is 1 km long by 600 meters wide and values of up to 37,900 ppm Cu and 21.6 ppm Ag were returned from a single mine working in this zone. One 250 m long hole is planned at Las Minillas.

Loma Coyote occurs 1400 meters northwest of Las Minillas, and overlaps an area 1200 meters long and 650 meters wide underlain by co-incident chargeability and resistivity highs. There are 4 mine workings in this area, and all 11 rock samples from the mines contain more than 10 000 ppm Cu. The best rock sample contains 68,300 ppm Cu and 114.3 ppm Ag. The best soil sample contains 18,700 ppm Cu and 10.9 ppm Ag. Five hundred meters in two holes are planned at Loma Coyote.

The Company plans to start the exploration in Q3 of 2013 pending permit approval by the Mexican Government.
