Arena Minerals Inc. Closes Agreement With Rouge Resources Ltd. on Sale of Pampas El Penon Project, Chile

TORONTO, ONTARIO--(Marketwired - Aug. 4, 2016) - Arena Minerals Inc., (TSX VENTURE:AN) (the "Company") is pleased to announce that it has closed its previously announced transaction with Rouge Resources Ltd. (TSX VENTURE:ROU) ("Rouge") for the disposition of the Pampas el Peñon gold project in Chile (see press release dated June 15, 2016). Arena's interest consisted of two option agreements (the "Option Agreements") with Sociedad Química Y Minera de Chile S.A. ("SQM"). In exchange for transferring its interest in the Option Agreements to Rouge, Arena has received consideration of 9,550,000 common shares of Rouge.

"We are very pleased to have closed the transaction with Rouge. The disposition of Arena's interest in Pampas el Peñon is consistent with Arena's prospector generator model of leveraging partners' capital to advance projects while still generating economic benefit for Arena shareholders. We are pleased with the support Rouge has received in the market for the transaction. Rouge will have the funding necessary to fully complete the Pampas El Peñon option. Arena shareholders will retain exposure to this project with enhanced liquidity prospects through Arena's shareholdings in Rouge. We look forward to Tim Warman and his team moving the project forward," said William Randall, President and CEO of Arena.

The Pampas El Peñon property consists of 13 mining claims totaling 3,400 hectares located approximately 130 kilometres southeast of Antofagasta, Chile. The property consists of two separate blocks, lying immediately to the west and north of Yamana Gold's Pampa Augusta Victoria mine complex that forms part of El Peñon mine complex.

Over $1,000,000 has been spent on the Pampas el Peñon property by Arena and SQM, with most of the work completed consisting of mapping, sampling, trenching and limited near-surface drilling designed to define the location of epithermal gold-silver veins with characteristics similar to those in the neighbouring Pampa Augusta Victoria complex.

The technical and scientific aspects of this news release have been reviewed and approved by Mr. Vernon Arseneau, P.Geo, who is a qualified person pursuant to NI 43-101. As the Vice President of Exploration of the Company, Mr. Arseneau is not considered independent.
