Glancy Prongay & Murray LLP (“GPM”) announces the filing of a class action lawsuit on behalf of investors who purchased Primero Mining Corp. ("Primero Mining" or the "Company") (NYSE: PPP) securities between October 5, 2012 and February 3, 2016, inclusive (the "Class Period"). Injured investors are encouraged to contact Lesley Portnoy of GPM at 310-201-9150 to discuss their legal rights.

On February 3, 2016, Primero Mining disclosed that its subsidiary, Primero Empresa Minera, S.A. de C.V., had received a legal claim from the Mexican tax authorities that sought to nullify the Advance Pricing Agreement issued in 2012. Upon this news, shares of Primero Mining dropped nearly 27% during intraday trading on February 4, 2016.

The Complaint alleges that throughout the Class Period, Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, prospects and performance. Specifically, during the Class Period, Defendants made false and/or misleading statements and/or failed to disclose that: (1) PEM was inappropriately recording revenues and taxes from sales under its silver purchase agreement between Primero Mining and Silver Wheaton; and (2) as a result of the foregoing, the Company’s public statements were materially false and misleading and/or lacked a reasonable basis at all relevant times.

Primero Mining investors have until April 15, 2016 to move the Court to appoint you as lead plaintiff if you meet certain legal requirements.
