Corona is committed to meet its production guidance for 2014. I look forward to working with the team at Corona in their continual efforts to be a low cost producer."

The following table sets out select unaudited financial information for the three and six months ended June 30, 2014 and 2013:

Corona's Financial Highlights

• Net income of US$ 7.0 million or US$ 0.194 per share for the second quarter of 2014 compared to US$ 1.8 million or US$ 0.051 per share for the same period in 2013. Net income of US$ 13.2 million or US$ 0.366 per share and US$ 11.0 million or US$ 0.305 per share for the six months ended June 30, 2014 and 2013, respectively.
• Adjusted EBITDA of US$ 15.4 million for the second quarter of 2014 compared to US$ 11.4 million for the same period in 2013. Adjusted EBITDA of US$ 28.3 million and US$ 28.6 million for the six months ended June 30, 2014 and 2013, respectively. The increase in adjusted EBITDA for the second quarter of 2014 compared to the second quarter of 2013 is mainly due to the increase in revenues and higher gross margins recorded during the period. This has been the result of the measures taken by the Company to increase operating efficiencies and reduce costs and which it has been implementing since the second half of 2013.
• Operating cash flow of US$ 10.5 million for the second quarter of 2014 compared to US$ 2.7 million for the same period in 2013. Operating cash flow of US$ 19.3 million and US$ 3.5 million for the six month period ended June 30, 2014 and 2013, respectively. The increase in operating cash flow is mainly the result of the higher revenues and gross margins and a US$ 8.5 million positive impact on working capital driven by lower payments of workers' profit sharing and taxes in 2014.
• Income taxes of US$ 4.2 million for the second quarter of 2014 compared to US$ 3.3 million in the same period of 2013. Income taxes of US$ 7.7 million and US$ 7.6 million for the six month period ended June 30, 2014 and 2013, respectively.
• Revenues of US$ 31.0 million for the second quarter of 2014 compared to US$ 27.3 million for the same period in 2013. Revenues of US$ 58.9 million and US$ 60.6 million for the six month period ended June 30, 2014 and 2013, respectively. The increase in revenues for the second quarter of 2014 compared to the second quarter of 2013 is mainly as a result of the higher lead head grades, higher silver and lead recoveries and a higher volume of mineral sold. This was partially offset by the decrease in the commodity prices compared to 2013.
• Cash and cash equivalents of US$ 33.9 million as at June 30, 2014 compared to US$ 36.2 million as of December 31, 2013. Cash and cash equivalents decreased by US$ 2.3 million mainly driven by US$ 19.3 million of operating cash flow, offset by US$ 14.6 million of dividend payments, US$ 6.4 million of capital expenditures and US$ 0.6 million of financing activities.
• Negative by-product cash cost per ounce of silver of US$ 19.67 at Yauricocha for the second quarter of 2014 compared to a negative by-product cash cost per ounce of silver of US$ 10.01 for the same period of 2013. Negative by-product cash cost per ounce of silver of US$ 20.33 and US$ 14.29 at Yauricocha for the six month period ended June 30, 2014 and 2013, respectively. Lower cash cost per ounce of silver during the first half of 2014 compared to 2013 is driven by lower cash cost per tonne processed and higher by-product credits. This is the result of the measures that the Company has been implementing since the second half of 2013 and which have resulted in operating efficiencies and cost savings.
