VANCOUVER, British Columbia, Oct. 15, 2020 (GLOBE NEWSWIRE) — FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ) announces that additional wide zones of mineralization have been intersected at Boundary West Zone on the Macmillan Pass Project, Yukon, Canada. Drilling has now been completed for the 2020 season. Assays for all holes are pending. An airborne VTEM-magnetic geophysics survey and final sampling of drill core are being completed as the camp winds down for the winter.


  • A total of 10 diamond-drill holes for 2,948 m, and 9 RC holes for 507 m have been completed
  • Hole NB20-008 intersected a wide zone of zinc-lead mineralization and has demonstrated continuity between previously announced holes NB-20-004 and 007, in a new discovery known as “Boundary West”, and the core of Boundary Zone
  • Hole NB20-009 was drilled from the same pad as hole NB20-007, which was lost, and intersected a wide zone of zinc-lead mineralization at the new Boundary West Zone

CEO Statement
Brandon Macdonald, CEO, stated “It has been a short but intense exploration season at Macmillan Pass where we had three drills working. Highlights for the season are several wide intersections of zinc-lead mineralization in long step out holes at Boundary West Zone for which we eagerly await assays. These include yet more wide zones of mineralization in new step out holes 008 and 009 at Boundary West Zone. We also drilled wide intersections in the heart of Boundary Zone and tested other targets as well. We will leave one drill and associated equipment in camp over the winter so we can get an early start next season to continue drilling these zones which remain open for exploration.”

Core Drilling
Infill and step-out drilling at Boundary Zone (Map 1) has successfully encountered wide zones of zinc-lead mineralization, significantly extending the footprint of the known mineralization. A total of nine holes were drilled at Boundary Zone this season for 2,948 m (Map 2). Three drill holes, NB20-004, -008 and -009, have discovered new wide sections of pyrite-sphalerite-galena mineralization which extends Boundary Zone at least 360 m to the west in a new discovery named Boundary Zone West. The holes were drilled on a new gravity high anomaly defined earlier this summer during the ground geophysics survey work. Two other infill holes at Boundary Zone also intersected wide zones of mineralization.

One hole was drilled at the end of the season on the 240 Mile Target which is a new exploration target marked by a gravity anomaly located between the Tom and Jason deposits (Map 3) (see Fireweed news release dated June 11, 2020 for details). This hole was drilled to a depth of 632 m before being suspended due to encroaching winter weather. It did not encounter the target horizon, and further geological and geophysical interpretation of this area is required. The hole was left open to allow potential drilling to greater depth to resume next season.

Assays are pending for all holes. Descriptions of all holes drilled this season are in the tables at the end of this news release.

Reverse Circulation (RC) Drilling
Infill holes at Tom and Jason were drilled (Map 4, Map 5), demonstrating the potential to use RC drilling as a low-cost alternative to diamond drilling for future upgrading of resource categories at shallow depths. Assays are pending for all holes.

Airborne VTEM-Magnetic Geophysics
A late season airborne VTEM-magnetic geophysics survey is being carried out over the western part of the Fertile Corridor including Boundary Zone. Results from this survey will be used to guide future exploration and drill targeting.

About Fireweed Zinc Ltd. (TSXV: FWZ): Fireweed Zinc is a public mineral exploration company focused on zinc-lead-silver and managed by a veteran team of mining industry professionals. The Company is advancing its district-scale 544 km2 Macmillan Pass Project in Yukon, Canada, which is host to the 100% owned Tom and Jason zinc-lead-silver deposits with current Mineral Resources and a PEA economic study (see Fireweed news releases dated January 10, 2018, and May 23, 2018, respectively, and reports filed on for details) as well as the Boundary Zone, Tom North Zone and End Zone which have significant zinc-lead-silver mineralization drilled but not yet classified as mineral resources. The project also includes large blocks of adjacent claims (MAC, MC, MP, Jerry, BR, and NS) which cover exploration targets in the district where previous and recent work identified zinc, lead and silver prospects, and geophysical and geochemical anomalies in prospective host geology.
