Arena Minerals Discovers Two New Copper Porphyry Prospects in the Atacama Copper Project and Provides Exploration Update

TORONTO, ONTARIO -- (Marketwired) -- 06/10/14 -- Arena Minerals Inc. ("Arena" or the "Company") (TSX VENTURE: AN) announces additional results of its initial regional exploration program on the 2,930 square kilometer Atacama Copper Property ("ACP" or "Property"), located in the Antofagasta region of Chile. Arena has discovered two additional copper porphyry prospects (Quebrada Honda & Pampa Paciencia North). The prospects are located approximately 20 kilometres northwest of Lomas Bayas and 19 kilometres northwest of the Spence copper mines respectively. To date, approximately 60% of Atacama Copper Project has been covered by field work, resulting in 7 porphyry target areas discovered of approximately 9 square kilometres each.

Quebrada Honda prospect was discovered by following up on coincident magnetic and radiometric anomalies approximately 8 kilometers south east of Cerro Barco. The area of interest sits on a major NW-SE trending lineament that passes through both Cerro Barco and Quebrada Honda and continues to the SE for several kilometres, passing through the Lomas Bayas mine. Prospecting and mapping located a large area of stockwork and brecciation coincident with the geophysical anomalies and associated with an east-west striking zone of intense fracturation/faulting that extends for at least one kilometre before being lost in overburden. The stock work consists of quartz-barite veinlets with strong hematization and epidote commonly associated with porphyry systems in the area and is flanked on all sides by outcropping areas of brecciated andesitic rocks. Preliminary sampling of the outcropping areas returned anomalous values of copper up to 0.16% Cu, in addition to arsenic and manganese anomalous values.. The target size in the Quebrada Honda prospect is approximately 4 square kilometers. Additional work on the target will consist of ground magnetic surveys, additional mapping, sampling and trenching.

Prospecting north of the Pampa Paciencia epithermal gold target has located a zone of quartz vein stock work and separate area of intense brecciation within a granodiorite intrusive. The two areas are approximately two kilometers apart and separated by sand and gravel cover and are closely associated with the intersection of N-S and NW-SE trending lineaments as well as a high radiometric anomaly. The breccia is strongly silicified and covers an area approximately 50 by 50 metres of outcrop and subcrop. Similarly, the quartz veinlet stockwork zone covers a slightly larger area of 50 by 100 metres before being lost under overburden cover. Initial results from prospecting of both outcrop areas has returned anomalous values in copper (up to 497ppm), antimony (up to 192ppm), arsenic (110ppm) and lead (greater than 1%) which are all indicative of relative proximity to porphyry mineralization. Mapping and chip sampling as well as additional prospecting are planned to better define this new target in the coming weeks.

Exploration Update

At Cerro Barco, an area of quartz-magnetite stockwork immediately west of the original showing has been mapped in outcrop. The area also contains several outcrops of with potassic altered andesitic rocks with moderate to strong fracturing and cross-cutting veinlets of quartz-magnetite with copper oxide in places. The zone of fracturing and stockwork mineralization has been followed to the north towards the Antofagasta Calama Lineament ("ACL") and the magnetic anomaly until it disappears under cover. This alteration combined with the already identified intense hematite-silica alteration and copper gold mineralization that returned values up to 2.3%Cu and 1.98 g/t Au adds to the quality and exploration potential of this porphyry target. Additional work is being planned for this prospect, including extensive geochemistry, detailed mapping, trenching and ground geophysics. The Cerro Barco target is considered a priority exploration area due to the combination of several positive factors for porphyry mineralization including favorable structural context (NNW-SSE major lineament intersecting the ACL), presence of magnetite-quartz-copper oxide stockwork, potassic alteration of feldspars, and strong propylitic alteration of surrounding andesites, hematization and silicification.

In addition to the above mentioned prospects, regional prospecting has identified an area approximately ten kilometers east of Quebrada Honda with evidence of historical artisanal mining. The pits generally strike N-S and contain copper oxide within quartz bearing structures. Initial grab sampling from this area has returned copper values up to 3.49% and gold values up to 1.42 g/t.

On the western portion of the ACP claim block, primarily contained within the Coastal Range metallogenic NS belt, several areas of interest have been discovered during reconnaissance fieldwork. Samples from two areas in particular, have returned mineralized samples ranging from 0.6% to 8.10% Cu. While prospects in this belt are typically mantos, copper porphyries have been discovered, including the nearby Antocuya copper porphyry currently in development stage.

Vernon Arseneau, Vice-President of Exploration of Arena, commented "We continue to add prospective target areas to our growing portfolio of prospects within the Atacama Copper Project. We intend to continue with our current program, which we believe is proving to be cost efficient and effective."

The Company intends to continue working on the prospects in conjunction with initial exploration of the remaining targets identified on the Atacama Copper Property that have not been worked to date. At present just over 60% of the land has been covered in the initial exploration program.

About Arena Minerals

Currently Arena Minerals has three properties under option covering approximately 309,230 hectares. All the properties are within the Antofagasta region of Chile, at low altitudes and within producing mining camps. The Company flagship asset is the Atacama Copper Property, consisting of 293,500 hectares of essentially undrilled ground in the heart of Chile's premier copper mining district. The Atacama Copper Property is adjacent to the Capricornio Property, forming part of a contiguous land package that can be worked in conjunction. In addition the Company also has the Pampas El Penon project, comprising a total of 8,650 hectares which is less than 1 km from Yamana's Agusta Victoria project and 10 km from the El Penon mine. On May 11, 2014, the Company reduced its land position with respect to the Pampas El Penon property to 2,400 hectares of worked claims and 6,250 hectares of greenfield claims. The Capricornio property, comprising 7,080 hectares, hosts a district scale gold silver epithermal system virtually unexplored at depth and open on strike. The Pampas El Penon and Capricornio properties comprise Arena Minerals highly prospective gold properties within an active mining region.
