Alexco Reports Increased Production in Second Quarter of Calendar 2011

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/03/11 -- Alexco Resource Corp. (TSX: AXR)(NYSE Amex: AXU) is pleased to report second quarter calendar 2011 production results from the Bellekeno mine in the Keno Hill Silver District, Yukon. Mill throughput increased by 4.9% and silver production increased by 3.8% over first quarter calendar 2011 performance, with lead and zinc production increasing 10.7% and 32.8% respectively.

Second Calendar Quarter Highlights

--  Silver Production of 464,324 ounces
--  Lead Production of 4,074,122 pounds
--  Zinc Production of 1,770,159 pounds

Processed ore for the quarter was 18,928 tonnes at an average grade of 822 grams per tonne silver, 10.5% lead and 6.5% zinc. Mine production during the same period was 22,166 tonnes at an average grade of 958 grams per tonne silver, 11.5% lead and 6.4% zinc. Metallurgical recoveries for silver were 92.8%, with 89% of the silver reporting to the lead concentrate, while recoveries for lead in lead con and zinc in zinc con were 93.2% and 64.8% respectively. Significant improvements in zinc recovery were made compared to the performance in the first calendar quarter.

Alexco President and Chief Executive Officer Clynt Nauman said, 'In early July, we reached the milestone of one million ounces of silver production since commissioning the Bellekeno mine during the fourth quarter of calendar 2010. During this second calendar quarter, we made steady progress on all fronts including mill throughput, ore tonnes mined, overall metal production and recoveries. A total of nine separate power outages resulted in a 15% reduction of mill throughput in June, but we are assessing alternatives for providing 100% independent electrical power generating capacity for the Bellekeno mine and mill during power outages. Although we continue to increase our daily mill throughput, the deferred production shortfall experienced in the second quarter requires revised production guidance for calendar year 2011, which the Company now estimates at between 2.2 million and 2.5 million ounces of silver.'

Average mill throughput during the quarter was 208 tonnes per day (tpd), with daily throughput highs in excess of 300 tpd. Mill throughput in July has been approximately 250 tpd, reflecting a significant reduction in the frequency of power outages over this past month. Work continues on increasing the mill throughput by optimizing the mill screening circuit and mill feed systems. Underground development work includes finalizing the paste backfill plant infrastructure as well as initiation of mechanized long-hole stoping in select areas of the Bellekeno mine. The longhole stopes will provide the majority of the ore for the mill in the last half of calendar 2011. At the end of June 2011, approximately 12,800 tonnes of broken ore stockpile was available, located both underground and on surface.

As announced recently (see news release dated July 27, 2011 entitled 'Alexco Announces Initial Resource Estimates for Lucky Queen and Onek'), resources have now been defined at Lucky Queen and Onek, increasing the total indicated resources defined at Alexco's properties in the Keno Hill District by approximately 40%. As a result of this significant increase in estimated resources, advanced exploration work continues apace at Lucky Queen where rehabilitation of underground access is in progress, and at Onek where final decisions on placement of underground access will be completed this month. In other activity, exploration drilling is continuing and will likely be escalated in the third calendar quarter to further work to define potential new silver resources at Bermingham and Flame & Moth, as well as test additional areas and targets in the district.

The scientific and technical information about mine development and operations at the Bellekeno project and other Keno Hill District properties on which this news release has been based was prepared by or under the supervision of Thomas Fudge, P.E., Senior Vice President, Engineering and Corporate Development for Alexco. Mr. Fudge has reviewed this news release, and is a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

Release of Financial Results for Fiscal Year 2011

Full fiscal year-end results are expected to be released the week of September 12, 2011, with an accompanying conference call to review financial results, provide updates on additional work at the Lucky Queen and Onek properties as well as other exploration activity, and progress at the Bellekeno mine operations. Specific times and details for the conference call will be released at a later date.

Keno Hill Silver District History

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