VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 16, 2012) - Alexco Resource Corp. (TSX:AXR)(NYSE MKT:AXU)(NYSE Amex:AXU) today reports silver production of 458,472 ounces during the second quarter of 2012, and 1,040,257 ounces in the first six months of 2012, approximately 14% improved from the same period in 2011. Lead and zinc production in the second quarter were 3.7 million and 1.3 million pounds, respectively, with 8.6 million and 2.9 million pounds produced year to date, as the Bellekeno mine in the Keno Hill Silver District, Yukon continues its second full year of commercial production. Alexco is well advanced in the engineering and development of two additional underground mines, anticipating mine production in the fourth quarter 2012. However, increasing environmental assessment and permitting delays may restrict the ability of the company to process material from the new mines until 2013. Despite potential regulatory delay for new underground operations, the company is maintaining its earlier production guidance of 2.2 to 2.5 million ounces of silver in 2012, with bias toward the lower end of the range if permitting delays continue. Exploration work targeting 29,000 meters of drilling continues apace on a variety of surface and underground resource development and exploration targets, with early examples of success previously published in initial resource statements for Flame & Moth and Bermingham.

Production was lower in the second quarter 2012 compared to the first quarter of the year primarily due to underground operations sequencing through lower grade material as per the mine plan, while positioning the mine for a higher grade and increased production capacity in the third quarter and beyond. The Keno Hill District mill, which processed 17% more tonnes compared to the same period in 2011, operated at a matched production rate to the Bellekeno mine, despite a variety of mechanically-based agitator, thickener and filtration delays related in part to the relatively lower grade ore processed, fixed plant maintenance and lead time to delivery on critical spares. Mill availability during the second quarter was 90% and mill throughput per hours of runtime continues to improve. In addition, mill production was suspended for approximately two days in June due to wildfires and subsequent redeployment of some employees and equipment to assist in fire control as well as support and assist local residents.

Average mill throughput during the quarter was 244 tonnes per day (tpd) compared to 208 tpd in the second quarter of calendar 2011, and 234 tpd for the first quarter of 2012.

Alexco President and Chief Executive Officer, Clynt Nauman, said, "Second quarter silver production was less than the previous quarter primarily due to anticipated lower mine grades; but there is no question we continue to make progress on ramping up mill throughput, and we look forward to an improved second half in 2012. Our greatest challenge will be on the permitting front for the two new mines we planned to commission in 2012. Although the company is confident of receiving the appropriate regulatory authorization to produce from the new Onek and/or Lucky Queen mines in 2012, the additional authorization to process the newly mined material through the existing Keno mill may very well be delayed into early 2013. The company is currently reassessing its Bellekeno underground plans to make up for this delayed production." Nauman continued, "On the other hand, our exciting news during the second quarter was the dramatic increase in overall silver resources, as we reported our initial resource estimates at the Flame & Moth and Bermingham deposits. We were able to identify nearly 14 million ounces of indicated silver resource and about 5 million ounces of inferred resources between the two separate properties. Those new resources have resulted in a 52% increase in Alexco's combined indicated resources at our Keno Hill properties."

About Alexco

Alexco Resource Corp. owns and operates the Bellekeno silver mine, one of several mineral properties held by Alexco which encompass substantially all of the historical Keno Hill Silver District located in Canada's Yukon Territory. Bellekeno, which commenced commercial production at the beginning of calendar year 2011, is Canada's only operating primary silver mine. Alexco's primary near-term exploration objective is to unlock value in the silver-rich Keno Hill District, and is focused on growth by advancing its promising District properties to development decisions. The Company's goal is to produce 7 million to 10 million ounces of silver annually within the next decade. Employing a unique business model, Alexco also provides mine-related environmental services, remediation technologies and reclamation and mine closure services to both government and industry clients through the Alexco Environmental Group, its wholly-owned environmental services division.

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.
