Guerrero and Partner Riverside Resources Inc. Find High-Grade Copper at the Cerro Azul Project in Guerrero, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 26, 2011) - Guerrero Exploration Inc. (TSX VENTURE:GEX) ("Guerrero" or the "Corporation") is pleased to announce that, in conjunction with Riverside Resources Inc. ("Riverside"), a 5.3 km by 0.8 km zone of rock chip and soil copper anomalism was delineated and drill target areas have been confirmed by assay results from the recently completed rock and soil sampling field program. Copper values as high as 10% Cu from rock chips and 1.8% Cu in soil samples are present.

The high-grade copper results so far found primarily within the southern portion of the Cerro Azul Project, include the Loma Coyote, La Minillas and Las Trojas target areas. A peripheral and parallel trending coincident lead – zinc anomalous zone was observed in the Las Trojas – La Minillas area. Barium has an association with Cu at the La Minillas prospect.

The sampling program identified a new area of arsenic, molybdenum, lead and zinc anomalism measuring 700 by 700 m in the northeast corner of the soil grid. More sampling, prospecting and mapping will be required to further develop this target.

Another target area for drill testing, Coacoyul, was also identified as a copper – mercury associated anomaly in the northern part of the 260 km² property during this first phase of the 2011 work program at Cerro Azul.

Riverside's technical team has collected more than 200 rock samples and 1850 soil samples thus far. Copper values for the rock sampling ranged from <5ppm Cu to >100,000ppm Cu (10%), while the soil sampling program reported results that ranged from <5ppm Cu to >18,000ppm Cu (1.8%).

Geological mapping of the southern portion of Cerro Azul has confirmed the presence of extensive argillic alteration of andesitic tuffs and subvolcanic intrusive and into sedimentary country rocks along epithermal vein and breccias networks following local faults. Rock units previously interpreted as granodiorite intrusive have been identified as areas of argillic alteration and silicification, such as that observed at Pedrillo prospect. The extent of the alteration and coincidence of geochemical anomalism observed in the soil sampling supports the concept of Cerro Azul property representing a large zonated volcanic epithermal system.

Detailed maps and figures that highlight multi-element geochemistry results and drill target areas have been posted on the Guerrero website. These maps show the multi-kilometer scale of individual targets and the collective trend of copper mineralization that follows aeromagnetic anomalies.

Further Property and Exploration Program Details

The 260 km² copper-gold Cerro Azul Project is located in the Guerrero Terrane of the highly productive Southern Mexican Gold Belt. The 2011 work program at Cerro Azul has better defined target zones that Riverside previously identified through initial reconnaissance exploration. The first phase exploration program found the Loma Coyote area to show alteration zoning and soil geochemistry that could be interpreted as a potential porphyry related copper-gold type target. The aeromagnetic highs coincident with andesitic porphyry and volcanic rocks could be the upper reaches of a shallowly covered possible porphyry system which will be further prospected during IP and drill testing in the coming months.

David Stadnyk, President & CEO of Guerrero Exploration Inc., stated, "The Cerro Azul Project has defined a high potential for metallic mineralization with the recently completed work program. The rock chip and soil copper anomaly has been identified and drill target areas have been confirmed with rock and soil samples returning copper values as high as 10% Cu and 1.8% Cu respectively which is exciting and encouraging for Guerrero."

Assaying and Qualified Person:

Samples were taken to Hermosillo, Mexico where ALS Laboratory Group's mineral division ALS Chemex crushed and pulverized each sample. The rejects remained with ALS Chemex while the pulps were transported to ALS Chemex's ISO 9001-2008 certified laboratory in North Vancouver, BC, Canada for analysis. A QA/QC program was implemented as part of the sampling procedures for the exploration program. Duplicate, standard and blank samples were randomly inserted into the sample stream prior to being sent to the laboratory.

The scientific and technical data contained in this press release was prepared under the supervision of Troy Gill, BSc (Geol.)., a member of the Australian Institute of Geoscientists, who acts as a "qualified person" under National Instrument 43-101 Standards of Disclosure for Mineral Projects.
