Vancouver, British Columbia: FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ) is pleased to provide an exploration update on the Macmillan Pass Zinc Project in Yukon, Canada.


A total of 4,225m of core drilling in 16 holes have been completed to date. First assays are anticipated in the coming weeks. Drill holes completed are:

  • Eleven step out and infill drill holes on the southern and northern extensions of the Tom West Zone
  • Two step out drill holes on the southern extension of the Tom East Zone
  • One drill hole on a new exploration target east of Tom
  • Two drill holes at End Zone

The next holes using two drills will test the following targets:

  • Step out drill hole on the Jason South Zone. This deep high grade zone was not drilled in 2017.
  • End Zone and area. The End Zone is a third high grade SEDEX zone open for expansion that was not drilled in 2017 and was not included in Fireweed’s 2018 Mineral Resource due to insufficient historic drilling data.

The first batches of core samples were cut and shipped to the laboratory in late July / early August, and additional batches of samples are shipped routinely as they are prepared.

Details and sections for some of these drilling areas are illustrated in the current Company presentation at .

Exploration for New Discoveries

Field work began in early June (see Fireweed news release dated June 5, 2018) with geophysical surveying and geochemical sampling orientation grids in the Tom, Jason and End Zone areas to optimize exploration methodologies. This test work demonstrated that geophysical gravity surveying complemented with passive seismics, and geochemical B/C horizon soil sampling, both guided by geological mapping and modern exploration concepts, are effective techniques to detect zinc-lead-silver mineralization in the district and efficiently focus targets for drilling. Since then, large gravity and soil sampling grids have been laid out and are being surveyed and sampled along with geological mapping. To date, 195 line kilometers of gravity surveying covering approximately 35 km2 has been completed, and 2,743 geochemical B/C horizon, 1,621 mobile metal ion (MMI) and 944 soil gas hydrocarbon (SGH) soil samples have been collected and submitted for analyses.  

Results to date of this gravity, geochemistry and geological work have successfully defined at least two new high priority targets with potential for new discoveries.   

In total, a crew of about 40 persons are in camp carrying out this extensive drilling and field work program.

Brandon Macdonald, CEO, stated “We started the season with step out drilling to expand some of the known zones at Tom West and Tom East. We are finishing the season with drilling of the high grade Jason South Zone and the nascent SEDEX system at End Zone. Meanwhile our field crews carried out geophysical, geochemical and geological work in search of new discovery targets. We took an efficient and cost effective approach, and I am pleased they were successful in defining at least two high priority drill targets so far.”

About Fireweed Zinc Ltd. (TSXV:FWZ): 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 large 470 km2 Macmillan Pass Project in Yukon, Canada, which is host to the 100% owned Tom and Jason zinc-lead-silver deposits with recently announced new 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). The project also includes option agreements on large blocks of adjacent claims (MAC, MC, MP, Jerry, BR and NS) which cover projected extensions of mineralization from the Jason area and areas where previous exploration identified zinc, lead and silver geochemical anomalies in critical host geology.
