NEWS RELEASE: PRIMERO TO ACQUIRE BRIGUS GOLD AND CREATE A DIVERSIFIED, AMERICAS BASED MID-TIER GOLD PRODUCER

TORONTO, ONTARIO–(Marketwired – Dec. 16, 2013) – (Please note that all dollar amounts in this news release are expressed in U.S. dollars unless otherwise indicated.)

Primero Mining Corp. (“Primero” or the “Company”) (TSX:P)(NYSE:PPP)(ASX:PPM) and Brigus Gold Corp. (“Brigus”) (NYSE:BRD)(TSX:BRD) today announced that they have entered into an arrangement agreement (the “Arrangement Agreement”) whereby Primero will acquire all outstanding common shares of Brigus pursuant to a plan of arrangement (the “Arrangement”) to create a diversified, Americas based mid-tier gold producer.

Pursuant to the Arrangement, Primero will acquire each outstanding Brigus common share for 0.175 of a Primero common share (the “Exchange Ratio”). In addition, Brigus shareholders will receive 0.1 of a common share in a newly incorporated company (“SpinCo”) for each Brigus common share as part of the Arrangement. SpinCo will hold Brigus’ interests in the Goldfields project in Saskatchewan and the Ixhuatán and Huizopa projects in Mexico and will be capitalized with approximately C$10 million in cash.

Upon completion of the Arrangement, Brigus shareholders will hold, in aggregate, a 90.1% interest in SpinCo and Primero will hold the remaining 9.9% interest in SpinCo. All outstanding options to purchase Brigus common shares will be exchanged for options to purchase Primero common shares based upon the Exchange Ratio pursuant to the Arrangement. Following completion of the Arrangement, each outstanding warrant to purchase a Brigus common share will be exercisable to purchase 0.175 of a Primero common share and 0.1 of a SpinCo common share.

The Exchange Ratio represents C$0.91 per Brigus common share, based on the closing price of Primero common shares (C$5.22) on the Toronto Stock Exchange as at December 13, 2013. This value implies a 43% premium to Brigus’ 20-trading day volume weighted average price (“VWAP”) and a 45% premium to Brigus’ closing price, both as at December 13, 2013 on the Toronto Stock Exchange, before ascribing any value to SpinCo. Upon completion of the Arrangement, Brigus will be a wholly-owned subsidiary of Primero and existing Primero shareholders and Brigus shareholders will own approximately 73.4% and 26.6%, respectively, of the outstanding Primero common shares, on a fully diluted in-the-money basis, before ascribing any value to SpinCo. The implied transaction value, before ascribing any value to SpinCo, is approximately C$220 million.

Highlights of the Transaction

  • Diversified production base: The proposed transaction transforms two single production asset companies into a single entity with operations in geo-politically stable jurisdictions, industry supportive infrastructure and prospective regional geology;
  • Critical production scale: Two producing gold mines with 250,000 to 270,000 gold equivalent ounces in 2014 at below industry average cash costs1, which could potentially increase to approximately 400,000 ounces in 2017 with the addition of the production from the Cerro del Gallo development project and a further expansion at San Dimas2;

  • Exploration opportunity: Combines two companies with demonstrated exploration upside, close to existing mine infrastructure (see recent exploration updates by both companies);
  • Re-valuation opportunity: With diversified production and cash flow, a strong balance sheet, a superior growth profile and a proven operating team, the combined company creates the potential for a re-rating to a multiple in line with other mid-tier gold producers.

Primero also has the financial and management resources necessary to advance the adjacent Grey Fox project at the same time as developing the Cerro del Gallo project in Mexico. Furthermore, this transaction represents an opportunity for Brigus shareholders to participate in the tremendous potential of the combined company.”

“We are pleased to be combining with another established producer, to diversify and build our financial strength and technical expertise while, at the same time, unlocking value for Brigus shareholders. Brigus shareholders will benefit from Primero’s strong balance sheet and cash flow, enabling further investment in the Black Fox mine to realize its full potential and the advancement of the Grey Fox project.
