Alexco Intersects 4.0 Meters of 1,640 Grams Per Tonne Silver, Discovers Gold to 14.8 Grams Per Tonne Over 1.0 Meter at Bermingham

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/04/13 -- Alexco Resource Corp. (TSX: AXR)(NYSE MKT: AXU) today announced results from the 2012 drilling program at its Bermingham and Husky properties in the Keno Hill Silver District in Canada's Yukon Territory.

At the Bermingham prospect, an additional 5,599 meters of drilling in 17 holes in 2012 has confirmed and expanded the area of previously discovered silver mineralization across a number of juxtaposed fault blocks. An earlier resource estimate at Bermingham identified 3.8 million ounces of indicated silver resource and a further 1.2 million ounces of inferred silver resource (see news release dated June 28, 2012 titled "Alexco Announces Initial Resource Estimates for Flame & Moth and Bermingham").

The 2012 results include up to 4.0 meters (true width) of 47.8 ounces per ton (opt) (1,640 grams per tonne (gpt)) silver which was intercepted approximately 300 meters east of the originally-defined resource. In addition, gold intercepts to 0.43 opt (14.8 gpt) gold over approximately 1.0 meter were drilled some 500 meters further along strike to the east. Silver mineralization is now known to extend at least 500 meters along strike and 400 meters down dip in the Bermingham area, and remains open. Review and update of the Bermingham resource is ongoing.

At the Husky prospect, located approximately 4 kilometers west of Bermingham, silver mineralization comprising 1.8 meters (true thickness) of 13.8 opt (474 gpt) silver has been intersected 200 meters below the lowest workings of the historical Husky mine and in a previously unknown vein structure in the footwall of the primary Husky structure.

Alexco President and CEO, Clynt Nauman, commented, "Bermingham is an integral part of our continuing program to build our consolidated silver resource inventory in the Keno Hill District, which inventory now totals 51.3 million indicated, 7.7 million inferred and 5.4 million historical silver ounces (see "Properties - Mineral Resources" at www.alexcoresource.com). The discovery of gold is important as the Keno Camp was traditionally presumed to be gold poor, which is now not the case at either our new Flame & Moth deposit, or at Bermingham. The Husky discovery, about 200 meters below historical workings, continues to demonstrate the vertical and lateral strength of the Keno Hill silver mineralizing systems adjacent to many historical workings."

2012 Bermingham Drill Assay Highlights

--  K-12-0477 intercepted the Bermingham structure over a true width of
    approximately 3.97 meters from 299.72 meters with an overall average
    silver grade of 1,640 gpt (47.83 opt). This intercept comprises a splay
    vein from 299.72 meters containing a composite assay value of 4,318 gpt
    silver (125.94 opt) over a true width of 0.75 meters, as well as the
    main Bermingham Vein from 302.97 meters containing a composite assay
    value of 2,467 gpt silver (71.96 opt) over 1.30 meters true width,
    including a smaller intercept of 0.28 meters true width from 303.50
    meters that graded 10,065 gpt silver (293.55 opt).

--  K-12-0465 intersected the Bermingham Vein over 2.01 meters true width
    from 224.13 meters with a composite assay value of 1,894 gpt silver
    (55.23 opt) that included 0.49 meters true width from 224.13 meters that
    graded 7,328 gpt silver (213.75 opt).

--  K-12-0446 intersected the Bermingham Vein over 4.92 meters true width
    from 229.81 meters with a composite assay value of 646 gpt silver (18.84
    opt) that included 1.07 meters true width from 230.72 meters that graded
    2,440 gpt silver (71.17 opt). K-12-0446 also intersected the Aho Vein
    over 0.53 meters true width from 85.64 meters with an assay value of
    10.30 gpt gold (0.30 opt) and 98 gpt silver (2.84 opt).

--  K-12-0459 intersected the Bermingham Vein over 1.73 meters true width
    from 258.03 meters with a composite assay value of 884 gpt silver (25.79
    opt) that included 0.78 meters true width from 258.42 meters that graded
    1,853 gpt silver (54.03 opt).

--  K-12-0485 intersected the Aho Vein over 0.99 meters true width from
    154.83 meters with an assay value of 14.85 gpt gold (0.43 opt).

The Bermingham prospect is located adjacent to and along strike of the Hector-Calumet mine mineralized vein system that historically produced 96 million ounces of silver. Previously-released results from Bermingham identified a relatively complex geological environment in which significant silver mineralization was developed within broad zones (typically 3 to 10 opt silver over 4 to 26 meters thick) that could be traced with confidence along strike for more than 400 meters and to a depth of at least 350 meters in two segments offset along the Mastiff Fault (the southerly Etta Zone and the northerly Arctic Zone). The 2012 drilling at Bermingham was designed to infill around the originally-defined Etta resource and to identify extensions of the major mineralized structures along strike to the west and in the footwall of the Mastiff Fault (Arctic Zone). Drilling in the Arctic Zone in 2012 has identified additional high grade silver mineralization and also extended the mineralization approximately 110 meters northeast and 90 meters southwest into further fault-bounded vein sections. The most northeasterly drill hole (K-12-0477) in the Arctic Zone intercepted the Bermingham structure over a true width of approximately 3.97 meters at an average silver grade of 47.83 opt.

In addition to silver-lead-zinc mineralization, significant gold assays have also been returned from the subparallel Aho Vein, including drill hole K-12-0446 that returned 10.30 gpt gold over 0.53 meters true thickness. The potential for significant strike continuity of this mineralized structure is demonstrated by another intercept of 14.85 gpt gold over 0.99 meters true thickness in drill hole K-12-0485, located some 500 meters to the northeast.

The Bermingham mineralized system remains open in all directions, especially to the northeast where linkage to the Hector-Calumet mine remains to be resolved, but also to the southwest where there remains a kilometer of untested ground to the historical Coral Wigwam mines.

2012 Husky Drill Assay Highlights

--  K-12-0423 intersected the Husky Vein over 1.81 meters true width from
    321.72 meters with a composite assay value of 474 gpt silver (13.83opt)
    that included 0.08 meters true width from 324.91 meters that graded
    3,060 gpt silver (89.25 opt).

--  K-12-0464 intersected the Husky Footwall Vein over 0.45 meters true
    width from 348.03 meters with an assay value of 416 gpt silver (12.13
    opt).

The Husky prospect is located at the historical Husky mine, which produced 18 million ounces of silver up until 1989. The mine is located near Elsa, about four kilometers to the west of Bermingham. Since the end of March 2012, 13 drill holes for 4,748 meters were completed, representing the first dedicated exploration below the historical mine workings that reportedly bottomed in ore-grade mineralization.

The 2012 drilling was concentrated on two main areas:

--  Down-dip of the historical Husky mine workings, where a mineralized vein
    was intersected in K-12-0423, thus extending the known dip extent of the
    mineralized system by almost 200 meters.

--  400 meters southwest of the historical Husky mine workings, where a
    second mineralized vein, previously unknown, was intersected in the
    footwall of the Husky Vein.

The discoveries beneath the old Husky mine and in the footwall of the main Husky structure are significant, as these open up further areas of potential mineralization along and beneath the historically productive Elsa-Husky - Husky Southwest structure which historically produced 48.5 million ounces of silver.

Tables showing 30 gpt silver cutoff composite assay grades (restricted to include a maximum of two meters unmineralized internal dilution) or significant gold values have been used to identify the mineralized zones, with all intervals adjusted to reflect true thickness, and are appended to this news release.

Updated composite assay tables, along with a drill hole location map and a long section plot, for the drill holes reported here are appended to this release, and are available for review on the Company's website at www.alexcoresource.com.
