Highlights of First Quarter

• Pre-tax income of $3.0 million and net income of $1.3 million ($0.02 basic and diluted earnings per share) for the three months ended March 31, 2012 on combined mining and environmental services revenue of $24.7 million

• Production of 581,808 ounces silver, over 4.9 million pounds lead and more than 1.5 million pounds zinc
• Realized metal prices during the quarter averaged US$32.81 per ounce silver, US$0.95 per pound lead and US$0.92 per pound zinc
• Cash costs of production¹ over the quarter of $11.01 per ounce of payable silver produced, net of by-product credits
• Cash flows from operating activities for the quarter of $7.2 million

¹ Cash costs of production per ounce of payable silver produced is a non-IFRS measure with no standardized meaning prescribed under IFRS. See page 12 of Alexco's March 31, 2012 MD&A for explanation and reconciliation.

Alexco President and Chief Executive Officer Clynt Nauman said, "We are pleased with our production performance during the first quarter, with results reinforcing our guidance for estimated production in 2012 of 2.2 million to 2.5 million ounces of silver, approximately 19 million pounds of lead and more than 7.5 million pounds of zinc. Operationally, our silver production increased 30%, our lead production grew by 37% and our zinc production increased 36% in the first quarter compared to the same period a year ago, while the mining rate climbed 30% and the milling rate increased 18% when comparing the two quarters. However, the quarter-on-quarter financial comparison was impacted by the significantly lower metals prices in the first quarter of this year compared to last year's first quarter." Nauman continued, "Consistent with our prior commitments, we are focusing on unit cost reduction at Bellekeno, an effort reflected in the 19% or $2.64 reduction in cost per ounce to $11.01 versus the fourth quarter of calendar 2011. We are continuing to look at structural changes in our operations to further improve efficiencies while also being mindful of continuing pressure on labour, consumable and energy costs. No question, our objective is an overall downward trend in unit costs over time, but we do recognize that costs will vary quarter to quarter as a result of factors both within and outside our control. Work also continues on the permitting activity required to bring Lucky Queen and Onek on line late this year, and the exploration program is scaling up apace with our plans."

Bellekeno Mine Operations

During the first quarter of 2012, the Bellekeno mine, located in the Keno Hill Silver District in Canada's Yukon Territory, produced 4,959 tonnes of concentrate comprising 3,376 tonnes of lead-silver concentrate and 1,583 tonnes of zinc concentrate. Average mill throughput in the three month period ended March 31, 2012 was 234 tonnes per day (tpd) compared to 201 tpd in the first quarter of calendar 2011 (the mine's first quarter of commercial production), and 245 tpd during the three months ended December 31, 2011. The reduction relative to the fourth quarter of calendar 2011 was primarily due to planned downtime related to the previously-announced campaign of throughput and metallurgical testing carried out to identify and assess any modifications which may be required to receive mine output from the Onek and Lucky Queen properties towards the end of the calendar 2012 year.

Cash costs of production over the over the first quarter of 2012 were $11.01 per ounce of payable silver, compared to $8.88 in the first quarter of 2011. The higher per-ounce costs of production are due primarily to reduced by-product credits as a result of a 21% lower lead price and a 14% lower zinc price as well as higher treatment and refining charges compared to the first quarter of calendar 2011. Overall, costs-per-ounce for mining, milling and transportation were generally consistent when comparing the first quarter of 2012 to the same period in 2011. However, cash costs per ounce in the first quarter were notably lower than the $13.65 per ounce reported in the fourth quarter of calendar 2011, reflecting significantly lower mining costs per ounce partially offset by reduced by-product credits due primarily to lower zinc grades and recoveries.

Comparative operating statistics for Bellekeno for the first quarter of 2012 are summarized as follows:

Keno Hill Exploration

Alexco's calendar 2012 exploration program in the Keno Hill District includes over 29,000 meters of surface and underground drilling, with an estimated cost of approximately $12 million. The program is expected to include 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. To date, eight of more than 20 holes planned at Flame & Moth have been completed, generally up-dip of the southerly mineralized zone drilled in 2011. Two drills will continue testing this and other areas to infill and expand mineralization at Flame & Moth during Phase I of this program. Alexco plans to report a preliminary resource at Flame & Moth by mid year. At Bellekeno, underground drilling is continuing on targets outside the existing resource both to explore beyond the areas of currently planned mining zones, and to ensure that additional planned underground development is properly located to further drill extension of the existing resource.

Rehabilitation of the historical Lucky Queen workings is continuing, and Alexco is in the process of developing access to the historical Onek workings, both with the objective of enabling advanced exploration drilling from underground to support mine planning and development decisions.

Financial Position

Alexco's cash and cash equivalents at March 31, 2012 totaled $36,795,000 compared to $41,741,000 at December 31, 2011, while net working capital totaled $42,955,000 compared to $47,997,000 for the same dates respectively. The decreases in cash and net working capital primarily reflect the transfer of approximately $3.8 million into long term restricted cash and deposits as security provided to support certain cost performance commitments under a remediation services contract entered into during the quarter by the Alexco Environmental Group, with net cash inflows from operations generally financing exploration expenditures within the Keno Hill District as well as Bellekeno mine development.

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.
