⁽¹⁾Adjusted earnings, mine operating cash-flow and cash costs are non-IFRS measures

Bradford Cooke, Chairman and CEO, commented, “Endeavour posted strong financial and operating results in the First Quarter, 2012. Thanks to rising silver and gold production, and robust precious metal prices, our sales revenues, operating cash-flow, net earnings and adjusted earnings were all up sharply. As a result, the Company’s working capital has never been stronger and we are well positioned to close in June the recently announced strategic acquisition of our third operating silver-gold mine in Mexico, the El Cubo mine in Guanajuato State. Endeavour is well on track to meet its production guidance for 2012. Management plans to provide further guidance regarding El Cubo and the Company’s revised production outlook for the year after closing.”

“As in previous years, our capital expansion programs at Guanacevi and Guanajuato commenced in the 1st Quarter and are scheduled for completion in the 3rd and 4th Quarters. Silver production will remain relatively flat and cash costs a bit higher than guidance reflecting our current focus on the capital programs. However, once the Guanajuato mine expansion from 1000 tonnes per day (tpd) to 1,600 tpd and the Guanacevi plant optimization from 1000 tpd to 1200 tpd are completed, production should start rising and cash costs should start falling once again.”

“In exploration, we currently have five drill rigs working, three at Guanajuato and one each at Guanacevi and the San Sebastian project in Jalisco. New property acquisitions in each of the two districts we operate in are currently in progress, and some exciting new property acquisitions elsewhere are now being evaluated. Initial results from our exploration and acquisition programs are expected this quarter.”

Financial Results (see Consolidated Statement of Operations)

Revenues increased 39% to $49.0 million in Q1, 2012 (Q1, 2011 – $35.4 million) thanks to sharply higher silver-gold production. The Company sold 1,100,000 silver oz and 6,497 gold oz at average realized prices of $33.10 per oz and $1,689 per oz respectively. Costs of Sales were up 73% to $25.6 million (Q1, 2011 – $14.8 million) primarily due to higher production, increasing labour costs and higher depletion rates on a per tonne basis.

Mine Operating Cash-Flow increased 30% to $32.0 million (Q1, 2011 – $24.5 million) and Mine Operating Earnings rose to $23.4 million (Q1, 2011 – $20.6 million). The Company realized positive Operating Earnings of $18.9 million (Q1, 2011 – $17.2 million), Operating Cash-Flow was $28.8 million (Q1, 2011 – $14.6 million) and Earnings Before Taxes were $25.2 million (Q1, 2011 – $5.1 million).

Net Earnings were $19.8 million ($0.23 per share) for the period after deducting an Income Tax Expense of $5.4 million (Q1, 2011 – $4.7 million). Net Earnings includes a mark to market derivative liability gain related to share purchase warrants issued in 2009 denominated in Canadian dollars, while the Company’s functional currency is the US dollar. Under IFRS, these warrants are classified and accounted for as financial liability at fair market value with adjustments recognized through net earnings. The appreciation of these warrants resulted in a derivative liability gain of $0.1 million compared to a $14.0 million loss in 2011.

Adjusted Earnings are $19.6 million ($0.22 per share) compared to $14.5 million in 2011 ($0.18 per share), excluding the derivative liability adjustments related to the warrants.

Cash Costs increased 35% to $6.26 per oz silver produced in Q1, 2012 (Q1, 2011 – $4.94 per oz) mainly due to down time at Guanacevi related to the connection with the new 115 kva state power supply and in part to wage increases, the appreciation of the Mexican peso and lower grade silver ores at both mines. Endeavour reports its cash costs according to the Gold Institute cash cost reporting guidelines.

Capital investments totaled $9.3 million in property, plant and equipment during the First Quarter, 2012. Their main focus was on continued underground development at the Guanacevi and Guanajuato mines, expanding our mining fleet and upgrading various circuits at the plants to handle increased throughputs.

At March 31, 2012, the Company held cash and short term investments of $131.6 million and working capital totaled $158.5 million, up $16.2 million from the end of 2011.

In January and February, 2012, gold and silver prices enjoyed a significant rebound from their lows in December, 2011. Endeavour therefore elected to sell most of the precious metal inventory it accumulated in Q4, 2011 in order to capture the higher gold and silver prices. However, gold and silver prices corrected sharply once again in March 2012 so Endeavour management once again chose to accumulate its precious metal production in Q1, 2012 rather than sell at depressed prices. As of March 31, 2012 the Company held 941,875 oz silver and 4,156 oz gold in metal inventory carried at cost on the balance sheet.

Operating Results (see Consolidated Table of Operations)

Consolidated silver production climbed 19% to 1,072,491 oz and gold production jumped 26% to 6,321 oz in Q1, 2012 compared to Q1, 2011 thanks to higher plant throughput at both Guanacevi and Guanajuato, partially offset by slightly lower ore grades and recoveries. As a result, consolidated silver and equivalent production rose 21% to 1.4 million oz (50:1 silver: gold ratio, no base metals) compared to Q1, 2011.

Consolidated plant throughputs in Q1, 2012 totaled 193,756 tonnes, up 37% compared to Q1, 2011 due to the 2011 plant expansion at Guanajuato. The Guanacevi mine averaged 1,087 tpd and the Guanajuato mine averaged 1,042 tpd during the First Quarter, 2012. Consolidated silver grades averaged 229 grams per tonne (gpt) silver (9.4 oz per ton) and gold grades averaged 1.33 gpt. Consolidated silver recoveries averaged 75% and gold recoveries averaged 76%.

Guanacevi silver production for Q1, 2012 was 726,697 oz, up 9% compared to 663,202 oz in Q1, 2011 and gold production was 1,620 oz, a decrease of 7% compared to 1,750 oz. Plant throughput was 98,963 tonnes at average grades of 292 gpt silver and 0.60 gpt gold, compared to 91,104 tonnes grading 307 gpt silver and 0.70 gpt gold in Q1, 2011. The increased silver production is attributable to the 9% increase in plant throughput and silver recoveries were also higher.

Guanajuato silver production for Q1, 2012 was 345,794 oz, up 44% compared to 236,931 oz in Q1, 2011 and gold production was 4,701 oz, an increase of 16% compared to 3,258 oz. Plant throughput was 94,796 tonnes at average grades of 163 gpt silver and 2.10 gpt gold, as compared to 50,838 tonnes grading 184 gpt silver and 2.53 gpt gold in Q1, 2011. The increased silver and gold production is attributable to the 86% increase in throughput, offset by lower grades and recoveries.

Outlook for Second Quarter, 2012

Management anticipates silver production and cash costs in Q2, 2012 will be comparable to Q1, 2012 while our operating teams focus on expanding the two mines and optimizing the two plants to attain 2012 throughput goals of 1200 tpd at Guanacevi and 1600 tpd at Guanajuato. We expect the direct costs per tonne at Guanacevi and Guanajuato will start falling once again later this year thanks to anticipated economies of scale as throughput increases at both operations.

Endeavour expects to close the previously announced El Cubo mine and Guadalupe y Calvo property acquisitions in Q2, 2012 once the Mexican government competition anti-trust review is completed. Revised 2012 guidance and our new conceptual long term growth plan will be outlined at that time.
