TORONTO, ONTARIO–(Marketwired – July 18, 2016) – Arena Minerals Inc., (TSX VENTURE:AN) (“Arena” or the “Company“) provides updates on activities and developments from its ongoing joint venture exploration programs. Drill campaigns on the Paciencia North and Solitario prospects have concluded and the joint venture is currently in the process of reviewing incoming results in light of the mandatory property reduction on July 26th, 2016. The Company, through work completed through its joint venture agreements and on land not under joint venture agreements, has met its minimum work commitments for the underlying option agreement with Sociedad Quimica y Minera de Chile (please refer to press release dated August 1, 2013). In addition, Arena is in a good position to make the upcoming payments for the underlying option agreement with significant cash on hand and approximately $2.3 million in funds to be received by July 26, 2016 (please refer to press release dated July 12, 2016). The Company will provide news on joint venture activity and option agreement land reductions as information is received.

Drilling permits for the Pampa Union drill program that forms part of the US$17.5 million Japan Oil, Gas and Metals National Corporation (“JOGMEC”) joint venture have been evaluated by the relevant authorities. The exploration program has been designed to complete a 1.5 kilometer grid spacing drill pattern over Pampa Union as well as follow up on previous successes. Drill hole PU-RC-39, drilled in the north western portion of the Pampa Union block, intersected a lithocap, alteration and pyrite shell characteristic of a porphyry system down to a total depth of 441 metres below surface. The follow-up 241 platform drill program was deemed to meet all necessary environmental, health and safety, fresh water resource management, archeological, communal, fauna and flora standards and was officially recommended for approval as described in the resultant Informe Consolidado de Evaluacion (“ICE”) issued by the Regional Environmental Assessment Service. On the July 15th, 2016 the Environmental Assessment Commission for the Antofagasta Region voted against the project deciding that the drillings could cause impact to historical heritage located at significant distance from any of the proposed drill platforms. As the permit was denied at the regional level the Company will file a claim (“Recurso de Reclamaci?n”) before the National Environmental Assessment Service in Santiago for final approval.

“We are pleased the Solitario and Paciencia drill programs have been completed on time. We now wait on these results to determine the development of these properties,” commented William Randall, President and CEO of Arena. “Given the favourable recommendations in the ICE, we are confident the permitting process will have a favourable result for our JOGMEC joint venture. We expect the permits to be received within a two to six month timeframe. These results will allow the joint venture to complete the remaining 1.5 kilometre grid drilling as well as follow up on the two porphyry systems discovered in previous drill campaigns.”

Pursuant to the Environmental Law the project owner is entitled to file a Recurso de Reclamaci?n, if the final decision of the Environmental Assessment Commission rejects the Declaracion de Impacto Ambiental (“DIA”) or imposes conditions or additional requirements that may be consider arbitrary or illegal. The above mentioned administrative complaint has to be filed within a term of 30 business days, counted from the public announcement of the issuance of the RCA which occurred on July 15, 2016.

For the Pampa Uni?n project, the complaint must be filed before the National Environmental Assessment Service in Santiago. Based on precedents, we forecast that the final decision may be issued between two to six months.

Once the resolution of the National Environmental Assessment Service is issued, such resolution can be challenged before the Second Environmental Court, located in Santiago.
