FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ) is pleased to announce that drilling and field work for the 2019 summer campaign has now started on the Macmillan Pass Zinc Project in Yukon, Canada.


  • Core drilling has begun on the first target at Tom North
  • Reverse circulation (RC) drilling has begun on Target R
  • The gravity surveying crew has arrived to begin work in the Fertile Corridor
  • Geological mapping, sampling, and prospecting are underway

Core Drilling

The first target to be core drilled this summer is Tom North, where three of the wide-spaced planned drill holes have now been completed. Samples are now being cut for shipment to the laboratory and an additional (fourth) hole has been added to the Tom North program to twin historic hole TS005 (drilled in 1952) to test the reproducibility of the historic results. Fireweed drilling elsewhere at Tom demonstrated that many early historic drill results under-reported grades due to poor core recoveries (see examples in 2017 and 2018 Fireweed drilling news releases).  The 2019 Tom North drilling is testing the continuity of mineralization along a 600 m long extension northwards from the large Tom West mineral resource. Positive drill results at Tom North have the potential to extend open pit and underground mine life, and improve economics described in the current Preliminary Economic Assessment (PEA).

RC Drilling

Reverse circulation (RC) drilling has begun at Target R to test a coincident gravity-magnetic and soil anomaly discovered in 2018. Target R is located 2.5 km north of the Tom West mineral resource. The next target for the RC drill is Jason North, which is a coincident geological-geochemical-geophysical target located just north of the large Jason Main mineral resource.

Field Exploration

Gravity survey crews have arrived on site and will begin surveying in the coming days. Gravity surveying is planned along the Fertile Corridor and will extend west from the 2018 survey area. In 2018, gravity surveys identified a number of targets that will be drilled this summer.

Geological mapping, sampling, and prospecting has begun with the aim to advance Fireweed’s understanding of the geological controls on mineralization and further delineate prospective areas on the large 544 km2 property.

Technical information in this news release has been reviewed and approved by Gilles Dessureau, P.Geo, Vice President, Exploration and a ‘Qualified Person’ as defined under Canadian National Instrument 43‑101.

About Fireweed Zinc Ltd.:

Fireweed Zinc is a public mineral exploration company focused on zinc 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 and End Zone which have significant zinc-lead-silver mineralization drilled but not yet classified as mineral resources. The project also includes option agreements on 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.
