VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 14, 2012) - Alexco Resource Corp. (News - Market indicators)(NYSE Amex:AXU) today announced final results from the 2011 drilling program at its recently discovered Flame & Moth prospect, located immediately adjacent to Alexco's milling complex within the Keno Hill Silver District in Canada's Yukon Territory. Overall, the drilling has increased confidence in the continuity and thickness of silver mineralization at Flame & Moth, with results to date returning average grades from 16 to 21 ounces per ton silver over true widths averaging 5.5 meters within the mineralized Flame Vein structure. The structure is now traced with confidence along a 500 meter strike length to a depth of 350 meters below surface. In addition, within the thicker zones of mineralization noted below, higher grade intervals ranging from approximately 30 ounces per ton silver over 1.15 meters to more than 100 ounces per ton silver over 0.14 meters are present. The mineralization is open at depth and down-plunge. Mineralization also remains open up-plunge between 150 meters depth and the bedrock surface present beneath extensive alluvial gravels.

Alexco President and Chief Executive Officer Clynt Nauman said, "Clearly we have a significant discovery at Flame & Moth, with a continuity, style and thickness which may be unique for Keno Hill. At this juncture we have two objectives at Flame & Moth, firstly to calculate an initial silver resource which should be available in the second quarter 2012, and secondly to accelerate and expand our 2012 drilling program to both in-fill and extend mineralization such that by the end of 2012, the ranking of Flame & Moth within the mine development pipeline at Keno Hill can be better assessed."

Highlights

Results at Flame & Moth to date include the following composite assay intervals:

• K-11-0362 intersected mineralized vein material over 8.90 meters true width from 266.90 meters with a composite interval of 693 grams per tonne (20.2 ounces per ton) silver that included a bonanza interval over 0.14 meters true width at 3,880 grams per tonne (113.2 ounces per ton) silver.
• K-11-0367 intersected veining over 11.07 meters true width from 323.00 meters with an average assay interval of 320 grams per tonne (9.4 ounces per ton) silver that included an interval of 1.15 meters true width at 1,348 grams per tonne (39.3 ounces per ton) silver.
• K-11-0371a intersected mineralization with an assay of 1,060 grams per tonne (30.9 ounces per ton) silver over 0.59 meters true width from 328.28 meters, within veining with a composite assay of 430 grams per tonne (12.6 ounces per ton) silver over 3.96 meters true width from 328.28 meters.
• K-11-0374 intersected an 11.08 meter true width vein structure from 342.52 meters with a composite assay of 311 grams per tonne (9.1 ounces per ton) silver, that included an interval of 0.60 meters true width at 1,450 grams per tonne (42.3 ounces per ton) silver.
• K-11-0387 intersected veining over 5.05 meters true width from 212.47 meters, with a composite assay of 454 grams per tonne (13.2 ounces per ton) silver that included an interval over 0.21 meters true width at 1,535 grams per tonne (44.8 ounces per ton) silver.
• K-11-0391 intersected mineralized veining over 6.92 meters true width from 231.94 meters, with a composite assay of 563 grams per tonne (16.4 ounces per ton) silver that included an interval over 0.82 meters true width at an average grade of 1,168 grams per tonne (34.1 ounces per ton) silver.

2011 Flame & Moth Geology Update and Results

The above results complete the reporting of 2011 drilling at the Flame & Moth prospect, discovered in 2010 at depth adjacent to the recently constructed Bellekeno mill. These are in addition to those previously announced (see news release dated September 7, 2011 entitled "Alexco Intersects 6.04 Meters of 31.5 Ounces Per Ton Silver at Flame & Moth, Significantly Expands Mineralized Zone"). Alexco has now drilled a total of 11,143 meters in 46 diamond drill holes (with 38 of these reaching target depths) since the discovery of blind mineralization, with 7,155 meters completed in 2011.

The northeast-trending, moderately southeast dipping mineralized Flame Vein structure has now been identified over a total strike length of approximately 500 meters within two fault offset segments. The deepest drill intersect is 350 meters below surface and the structure is open at depth down-plunge and along strike. The up-dip portion of the structure between approximately 150 meter depth and bedrock surface also remains undrilled. The mineralized section of the Flame & Moth structure varies between 2.3 and 11.7 meters true width and averages approximately 5.5 meters.

Mineralization within the structure comprises multiphase quartz and siderite containing significant and locally massive, galena, sphalerite, pyrite and pyrrhotite with associated silver sulphosalts, arsenopyrite and chalcopyrite mineralization. Gold is locally present within the vein structure, with gold grades to 2.1 grams per tonne over intervals up to 1.03 meters as present in K-11-0362 from 266.90 meters. The continuity and consistency in silver grade of the vein mineralization has now been confirmed at approximately 60 meter drill centers and provides a sufficient level of confidence for Alexco to proceed to an estimate calculation to be undertaken by SRK Consulting (Canada) Inc. during the second quarter of 2012.

The discovery of this significant new blind deposit in the Keno Hill silver district gives Alexco confidence that continued exploration investment will continue to successfully add new resources, as the geology of the district becomes better understood.

Notes

The 2011 exploration drill program and sampling protocol has been reviewed, verified and compiled by Alexco's geologic staff under the supervision of Alan McOnie, Vice President, Exploration for Alexco and a Qualified Person as defined by National Instrument 43-101 ("NI 43-101"). A rigorous quality control and quality assurance protocol is used on the project, including blank, duplicate and standard reference samples in each batch of 20 samples delivered to the assay lab. Drill core samples were shipped to ALS Minerals Labs at Whitehorse, Yukon Territory for preparation, with fire assay and multi-element ICP analyses completed at the ALS Minerals facility in North Vancouver, British Columbia. The disclosure of scientific and technical information about Alexco's mineral projects contained in this news release has also been reviewed and approved by Mr. McOnie.

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.
