Hecla Receives C$40 Million Investment from Ressources Quebec

Hecla Mining Company (NYSE:HL) today announced that Ressources Quebec, a wholly owned subsidiary of Investissement Québec, is making a C$40 (US$31.6) million loan investment in Hecla (“the investment”).

The investment will be in the form of a senior unsecured term loan with a coupon rate of 4.68%, to mature at the same time as the outstanding high yield notes, in 37 months. The proceeds are to be used for development and expansion of the Casa Berardi mine located in the Abitibi-Témiscamingue region in Quebec.

“Today’s announcement is another example of why Quebec is a leading mining jurisdiction in North America,” said Phillips S. Baker, Jr., Hecla’s President and CEO. “Since we acquired the Casa Berardi mine, we have seen a significant improvement in its operations, including doubling the throughput, increased gold production and reserves, and a 70% reduction in the All Injury Frequency Rate. We have also added about 250 workers to the mine since it was acquired, bringing the total to around 950 currently. We welcome this opportunity to work closer with the Quebec government as we continue to grow and strengthen the operation.”
