Details of the plan of arrangement will be announced in due course.

“I am very pleased that so many Oromin shareholders have agreed to participate in our vision for the consolidation of our respective properties, a combination that unlocks not only immediate operational synergies but more importantly the opportunity to bring the OJVG property into production in the near term,” said Alan R. Hill, Executive Chairman of Teranga.

Mr. Chet Idziszek, President and director of Oromin, commented, “We are very pleased with this transaction from an Oromin perspective as it not only offers Oromin shareholders an attractive upfront premium it also allows all shareholders - Teranga and Oromin - to participate in the value creation we would anticipate from a combined operation, and in particular leveraging Teranga’s existing infrastructure and operational capabilities with the OJVG’s high grade, near surface ore.”

“With the OJVG deposits in production, we would anticipate increased production, earnings and free cash flows from Teranga’s interest in the OJVG open pit reserves. We truly believe this is a win-win for all parties and we are confident that we can work with all shareholders including the Government of Senegal to realize value.” added Richard Young, President and CEO of Teranga.

This release contains forward-looking statements and information within the meaning of applicable Canadian securities laws and the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995. These statements are based on management’s current expectations and beliefs and are subject to a number of risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements.
