VANCOUVER, BC, Nov. 9, 2021 /PRNewswire/ - Alexco Resource Corp. (NYSE:AXU) (TSX:AXU) ("Alexco" or the "Company") today reports financial results for the quarter ended September 30, 2021 ("Q3 2021"). The Company also provides an update on capital development projects, scale up of mining operations, and exploration activities at Keno Hill.

Highlights

Transitioned to Bermingham ore and on track to reach Flame & Moth ore in the fourth quarter of 2021 ("Q4 2021") and reach sustainable design capacity and planning for cash self-sufficiency in first quarter of 2022 ("Q1 2022"):

Bellekeno: Longhole drilling and blasting continued at Bellekeno, providing mill ore feed during Q3 2021. Ore production at Bellekeno concluded in October 2021.
Bermingham: Initial ore production was achieved in August 2021 and continues in Q4 2021, and grades to date have been consistent with block model estimates. In October 2021, the mill transitioned from milling ore sourced from the Bellekeno mine to milling ore sourced from the Bermingham mine.
Flame & Moth: Underground development activities at Flame & Moth continue, with initial ore production anticipated later in Q4 2021. Development of the Flame & Moth primary decline has reached the location of the first two ore access levels and advancement of the level accesses to the ore and construction of the Alimak raise nest is underway.

Mill Performance, Throughput and Recovery on Track: The Keno Hill District mill continued normal operations in Q3 2021, on a reduced schedule to accommodate the "milling out" of final tonnes from Bellekeno along with mechanical and electrical work to tie in the new ball mill and regrind mills which will be brought on-line to optimize throughput and concentrate quality from the Bermingham and Flame & Moth mines. The mill saw throughput of 162 tonnes per operating day ("tpd") in Q3 2021 as ramp up continues towards milling 400 tpd. The operational decision to stockpile 2,468 tonnes of Bermingham ore while Bellekeno ore was being milled separately resulted in slightly reduced throughput for Q3 2021 of 162 tpd compared to 176 tpd achieved in Q2 2021. For the first nine months of 2021 ("YTD"), mill throughput totaled 22,021 tonnes at 775 grams per tonne ("g/t") silver ("Ag"). Metallurgical performance in Q3 2021 was within design expectations for Bellekeno ore and additional optimization and adjustments are anticipated as the mill feed source transitions to solely Bermingham ore. For Q3 2021, Ag recoveries averaged 95%, with 98% of Ag reporting to the lead ("Pb") concentrate.
Announced Interim Exploration Results from Bermingham Northeast Deep Zone: On September 7, 2021, the Company announced interim results from Bermingham drilling, including composite assays to 1,681 g/t Ag over 20.37 meters ("m") true width. The interim results confirmed the presence of an approximate 500 m long sub horizontal mineralized zone with at least a 100 m vertical extent located approximately 150 m below the Bermingham Northeast Mining Reserve. The Bermingham Northeast Deep zone exploration and resource definition drilling was completed in October for a total of 17,830 m drilled, with 51 intercepts of the targeted mineralized vein zone. Final results are anticipated to be available in late 2021 and work is underway to develop a new Mineral Resource, also anticipated to be completed in late 2021. Total exploration expenditures capitalized during Q3 2021 were $3,811,000.

Outlook

"This quarter was a major turning point for us at Keno Hill," remarked Clynt Nauman, Chairman and CEO. "With ore extraction completed at Bellekeno, and our team now completely focused on our two new mines (Bermingham and Flame & Moth), we are rapidly moving closer to 'full production' and planning for cash flow self-sufficiency at Keno Hill. All major PPE expenditures for the site are complete and our Q4 focus is on completing underground development to achieve concurrent ore production from the Bermingham and Flame & Moth mines. Early development ore from the 1150 level at Bermingham was stockpiled in September and is now moving through the District mill and producing a high grade silver concentrate as anticipated. Underground advance rates this quarter were up approximately 26% over Q2 2021, which has allowed us to reach the first two ore access levels at Flame & Moth, with initial ore production anticipated in late Q4 2021. Once the Flame & Moth Alimak raise is completed in early 2022 we will be able to fill the mill and sustainably reach our targeted production levels. This quarter also saw us complete drilling on the Bermingham Northeast Deep exploration target, which has returned some exceptional interim results with composite assays to 1,681 g/t Ag over 20.37 meters true width. We are currently advancing the work required to develop a new Mineral Resource estimate for the Bermingham deposit to include the Northeast Deep zone, to be completed later this year."
