“Today marks an important milestone in Coeur’s transformation to the sector’s newest senior precious metals producer,” said Mitchell J. Krebs, Chairman, President and Chief Executive Officer. “With the New Gold acquisition now complete, the addition of New Afton and Rainy River increases our expected overall gold production by 80% and adds meaningful copper production alongside our dominant silver production profile. The tremendous free cash flow profile from our combined platform of seven North American operations will allow the Company to meaningfully accelerate and enlarge its return of capital strategy while also further bolstering our overall liquidity position. This strong financial position – along with the deep and talented combined team we are creating – will give us the flexibility to fund a pipeline of attractive organic growth projects and emerging new opportunities such as progressing the K-Zone at New Afton, advancing studies at our Silvertip silver project, and investing in high-return exploration programs across the portfolio.

“After having an opportunity to spend time at New Afton, Rainy River, and in the Toronto office and meet many of our new team members and important stakeholders, we are excited about building on these relationships and delivering the compelling benefits of this combination to our shareholders and to Canada going forward.”
