Alexco Resource Corp (TSX:AXR,NYSE-American:AXU) today announced initial results from its ongoing 2018 drilling program at the high-grade Bermingham deposit in the Keno Hill Silver District in Canada’s Yukon Territory.

Alexco Resource Corp (TSX:AXR,NYSE-American:AXU) today announced initial results from its ongoing 2018 drilling program at the high-grade Bermingham deposit in the Keno Hill Silver District in Canada’s Yukon Territory. Infill resource and peripheral zone drilling is currently underway from underground in the Bermingham exploration decline and from surface (for deeper extensions). The drilling will further define the previously outlined resource (858,000 tonnes with an average grade of 628 grams per tonne (“g/t”) silver (“Ag”) totaling an indicated 17.3 million ounces of silver), as well as more accurately outline and/or extend the upper zone of the potentially mineable tonnes (totaling 220,000 tonnes with an average grade of 1,276 g/t silver) included in the updated preliminary economic assessment dated March 29, 2017 (see news releases dated December 8, 2016, entitled “Alexco Expands Bermingham Silver Deposit, Initial Tests Confirm Excellent Metallurgical Performance” and  news release dated March 29, 2017, entitled “Alexco and Silver Wheaton Amend Silver Purchase Agreement and Alexco Announces Positive Preliminary Economic Assessment for Expanded Silver Production at Keno Hill”). In addition, Alexco announces updates on permitting for the Bermingham deposit and underground development at the Flame & Moth deposit.

Highlights

In 2018 a combined total of 26 holes have been drilled from surface and underground at the Bermingham deposit with results available from 14 holes and include the following highlights:

  • Significant silver-rich intercepts have been obtained from fourteen infill holes drilled within or proximal to the Bermingham resource. True width intercepts of the Bear Vein ranging up to 12.28 meters (“m”) grading 1,019 g/t (32.8 ounces per tonne (“oz/t”)) Ag in hole BMUG18-012 and 2.28 m grading 9,723 g/t (312.6 oz/t) Ag in drill hole BMUG18-015 (see Assay Composite Table, Drill Hole Location Map and Drill Hole Detail Table in the Appendices of this news release);
  • Other significant intersections from the associated Bermingham and Bermingham Footwall veins include true width intercepts of 4.17 m grading 5,373 g/t (172.8 oz/t) Ag in hole BMUG18-015 and 4.26 m grading 1,958 g/t (63.0 oz/t) in hole BMUG18-008;
  • Alexco received a positive Decision Document on July 27, 2018 by the Yukon Government for the development and production at the Bermingham deposit. Alexco has submitted a water license renewal application to the Yukon Water Board for processing and milling ore from the Bermingham mine; and
  • Advancement of the Flame & Moth decline continues with the drive ~45% complete and continuing apace.

Alexco Chairman and CEO Clynt Nauman commented, “The primary goal of our Bermingham exploration program is to confirm and expand the Bermingham silver resource through tightening up drill spacing within the resource and potential production areas and to better define open extensions. We are meeting success on all fronts. As we systematically expand the drill coverage, our understanding of the complex mineralized vein system, including the high grade Bear Vein, continues to increase. In the meantime continued exploration drilling from the surface in the vicinity of the Bermingham deposit is expected to also contribute to a new resource estimate which will be released concurrent with our prefeasibility study either late Q3 or early Q4. Not to be overshadowed, we have achieved a milestone with the submission of the water license renewal application while also increasing the pace of our Flame and Moth underground development.”

Drilling

To date, eleven underground drill holes and three surface holes totaling 2,396 m of HQ core drilling at Bermingham have assays completed. The drilling results confirm the vein model interpretation and continuity of significant high grade silver values. The interconnected mineralized vein systems at Bermingham include very high grade shoots such as the Bear Vein where our curre­nt Preliminary Economic Assessment mine plan identifies 220,000 potentially mineable tonnes grading 1,276 g/t Ag, sitting within more extensive zones of “lower” grade mineralization with true widths up to 8.62 m thick grading more than 600 g/t Ag (see news release dated March 29, 2017, entitled “Alexco and Silver Wheaton Amend Silver Purchase Agreement and Alexco Announces Positive Preliminary Economic Assessment for Expanded Silver Production at Keno Hill”).

Since the completion of the underground exploration decline at Bermingham in May 2018, underground resource infill drilling utilizing two drill rigs commenced and to the date of this release, 3,650 m of underground HQ core drilling has been completed in 21 drill holes. At the same time, surface drilling to complement and extend the deeper part of the resource commenced in early June, and to date five holes for 1,499 m of HQ core drilling has been completed. Assay results for 14 of these 26 holes have been completed and are reported here.

The underground drill program is designed to provide close spaced intersections at 10 – 15 m of the high-grade Bear Vein Indicated Resource that might allow conversion to a Measured Resource category in the upper levels of planned mine development once the program is complete, and to also intersect the other adjacent Bermingham veins to extend the current resource.

Permitting Update

Alexco has completed the environmental assessment process for the Bermingham Development and Production Program with the issuance of a positive Decision Document on July 27, 2018 by the Yukon Government as the Decision Body. The Decision Document outlines a number of standard terms and conditions for the development and mine production at the Bermingham deposit. These terms and conditions will be incorporated into the Company’s Quartz Mining and Water Licences for Bermingham. With the issuance of the Decision Document, Alexco has recently submitted a water license renewal application to the Yukon Water Board for processing and milling ore and discharging treated water from the Bermingham mine.

Mine Development Update

Following completion of the Bermingham exploration decline in early May 2018, Alexco relocated its underground mine development team and equipment to the Flame and Moth deposit to resume decline and ramp development. To date, 283 meters of primary development has been completed including supporting remuck bays and sumps. The Flame and Moth decline is being constructed at a design of 15% grade and sized 3.7 m wide x 4.0 m high and will accommodate new underground drilling headings as well as haulage of a planned 260 tonnes of ore per day to the primary crusher which is located within 200 m of the mine portal. Approximately 310 m of ramp development and supporting remuck bays remains to reach the first ore level access at the Lightning Zone within the Flame and Moth deposit.
