Alexco Releases Initial Production Results for Bellekeno Mine; On Track for 2011 Silver Production of 2.8 Million Ounces

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/03/11 -- Alexco Resource Corp. (TSX: AXR)(NYSE Amex: AXU) today reported the first full quarter production results from its newly commissioned Bellekeno mine and mill in the Keno Hill Silver District, Yukon.

First Quarter Highlights

--  Silver Production of 447,524 ounces
--  Lead Production of 3,682,304 pounds
--  Zinc Production of 1,334,144 pounds

As planned, production activity at the Bellekeno mine during the first three months of calendar 2011 included optimization of the mill circuit using a blended ore feed from both underground mining and stockpile inventories to stabilize the ore feed grade and character. This managed ore feed approach to initial production at the Bellekeno mill has resulted in increased metal recoveries and higher values for initial concentrate shipments. Alexco President and Chief Executive Officer Clynt Nauman said, "The mine and mill crews have done an outstanding job in challenging weather conditions to bring our Keno Hill Silver District back into production after twenty years of dormancy."

Processed ore for the quarter was 18,050 tonnes at a grade of 829 grams per tonne silver, 10.0% lead and 5.0% zinc. Mine production during the same period was 16,461 tonnes at an average grade of 1,062 grams per tonne silver, 12.5% Pb and 7.1% zinc. Metallurgical recoveries for silver, lead and zinc were 93%, 90% and 56% respectively, with 90% of the silver reporting to the lead concentrate.

Nauman said, "We have some remaining mill modifications and production efficiencies to implement, and we are confident that as a result of those improvements, the daily throughput of the mine and mill will systematically continue to increase. We are maintaining our current guidance for calendar year 2011 production of 2.8 million ounces of silver."

Average mill throughput during the quarter was 201 tonnes per day (tpd), with daily throughputs as high as 320 tpd. Once the initial ramp up phase is completed, the average daily throughput is anticipated to increase beyond 250 tpd and ultimately to be in the range of 350 to 400 tpd. The lower average daily throughput for the quarter was a result of intermittent interruption of processing for mechanical modifications of the mill circuit, coupled with the normal challenges of ramping up a new mill during a winter quarter. By the end of the quarter, average mill availability was greater than 90%. Mechanical optimization of pumping and piping circuits will continue in the second quarter of calendar 2011, with focus on the grinding/classification balance as well as additional work to improve zinc recovery.

There was considerable stockpiled ore available in the first quarter of calendar 2011, allowing for additional mine development totaling 244 meters at Bellekeno. Some of this development is in preparation for local mechanized long-hole stoping, an efficient mining method not previously tried at Keno Hill. Overall, mine operations in the first quarter of calendar 2011 generally maintained pace with processing activity while ending the quarter with a broken ore stockpile of approximately 9,500 tonnes.

Total silver production to date from Bellekeno, including results from commissioning during the fourth calendar quarter of 2010, is 573,541 ounces.

Keno Hill Silver District History

Between 1921 and 1988, the Keno Hill Silver District produced more than 217 million ounces of silver with average grades of 40.5 ounces per ton silver, 5.6% lead and 3.1% zinc (Yukon Government's Minfile database). The historical production grades would rank Keno Hill in the top 3% by grade of today's global silver producers. The Keno Hill Silver District is the second-largest historical silver producer in Canada.
