March 5, 2012 Alexco Resource Corp. (TSX:AXR, NYSE AMEX:AXU) today announces plans to increase exploration spending by 50% to $12 million in 2012. The Company will expand its efforts in both surface and underground exploration in the Keno Hill Silver District, Yukon, where its Bellekeno mine continues to ramp up silver production to an estimated 2.2 to 2.5 million ounces of silver in 2012.

Alexco conducted a highly successful exploration program in 2011. Especially notable were the new and expanded discoveries at the Flame & Moth and Bermingham properties, both of which were recently reported with additional positive drilling results. Alexco plans over 29,000 meters of drilling in the District during 2012, including approximately 4,500 meters of drilling underground at the Bellekeno mine, approximately 2,000 meters underground at the Lucky Queen project, and a minimum of 23,000 meters of surface exploration and definition drilling at various locations throughout the District.

2012 Keno Hill Exploration Highlights

Underground Exploration

  • At Bellekeno, mine extension targets that are down dip and down plunge of the high grade Southwest Zone will be tested beginning this month, including offset mineralization (approximately 150 meters offset) where initial surface discovery holes have identified up to 2,729 grams per tonne silver (79.6 ounces per ton) over 0.4 meters in a structural setting similar to the main Bellekeno silver deposit.1
  • At Lucky Queen, where underground development is currently underway, an indicated resource of approximately 124,000 tonnes of 1,227 grams per tonne silver (approximately 36 ounces per ton silver) has been outlined, and remains open both down dip and down plunge.2 Drilling for underground definition, resource expansion and exploration is planned at this very high grade deposit later in 2012.
  • At Onek, underground development in the silver rich southwest zone of the deposit is scheduled for 2012, with underground exploration beyond the existing resource model scheduled for 2013. The Onek deposit contains indicated resources of 585,000 tonnes of 13.7% zinc with 194 grams per tonne silver.3

Surface Exploration

  • Exploration at the newly outlined Flame & Moth discovery will be accelerated and expanded to at least 4,000 meters of infill and extension drilling. Results to date at Flame & Moth have returned average grades of 16 to 21 ounces per ton silver over 5.5 meters true width, within a structure traced with confidence along a 500 meter strike length to a depth of 350 meters below surface.4 It is anticipated that two drills will begin work in this area, close to the Keno District mill, within the next month. Resource modeling is currently underway at Flame & Moth with an aim of publishing an initial resource estimate in the second quarter 2012, though the 2012 exploration program is also being designed to enable a possible update to that initial resource estimate by the end of the year.
  • At Bermingham, infill and extension drilling will start later in April and likely continue all season to further delineate and expand this blind discovery where zones of silver mineralization up to 26 meters true thickness have been outlined including narrower intervals such as 1,634 grams per tonne silver (47.65 ounces per ton) over 1.8 meters.5 Resource modeling, where drill density permits, is also underway at Bermingham, with initial results anticipated in the second quarter of 2012. Further blind target concepts in the vicinity of Bermingham and adjacent to the nearby historical Hector Calumet mine (past production of over 90 million ounces of silver) will also be tested later in 2012.
  • A systematic exploration drilling program will be conducted in the area of the historical Elsa mine (past production of 30 million ounces of silver) and the fault- related historical Husky mine (past production of 13 million ounces of silver), where there is high potential for development of as yet undiscovered mineralization related to either historical deposit.
  • As well, Alexco will commence a grass roots gold exploration program approximately 9 kilometers west of Elsa at the McQuesten gold prospect, where previous explorers have identified up to 3.23 grams per tonne gold over 21.3 meters developed in or adjacent to intrusive rocks.6

From June 2006 through calendar 2011, Alexco has drilled 331 diamond drill holes totaling approximately 73,400 meters in the Keno Hill Silver District, as well as another 344 holes and 37,600 meters drilled from surface and underground specifically in the Bellekeno mine area. Alexco has also completed 34 reverse circulation drill holes totaling 1,150 meters in areas of deep alluvial cover and 283 sonic drill holes totaling approximately 910 meters in the area of the historical Elsa tailings. Over this period, the Company has additionally flown 2,016 line kilometers of airborne geophysics, and has compiled approximately 35,000 historical production and exploration documents into a 300 gigabyte digital database.

To date, only 18 of the approximately 35 known historical silver mines within Alexco’s Keno Hill Silver District land holdings have been drill tested. In addition, and apart from the historical silver mines, work on known gold occurrences at McQuesten and Keno Hill has generally been deferred in prior year programs, a situation which will change in 2012.

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.
