Fireweed Zinc reveals drilling update on MacMillan Project

FIREWEED ZINC LTD. (TSXV: FWZ) has provided an update on its exploration program at the Macmillan Pass Zinc Project in Yukon, Canada.

FIREWEED ZINC LTD. (TSXV: FWZ) has provided an update on its exploration program at the Macmillan Pass Zinc Project in Yukon, Canada.


-12 core drill holes completed; seven at the Tom North target, one at the Tom West Zone, one at the Tom East Zone, one at Target R and two at the Jason North target. Drilling now started at Target A.

-Gravity geophysics crews have completed surveying about half of Fertile Corridor between End Zone and Boundary Zone.

-Airborne LiDAR topographic surveying is 80% complete.

-Geological mapping, sampling, and prospecting are continuing.


Drilling started at the Tom North target to test a 600m long potential north extension of the large Tom West mineral resource (see Figure 2). Three holes were initially planned but the program was expanded and seven holes have been completed. Positive drill results at Tom North have the potential to extend open pit and underground mine life, and improve Tom economics described in the current Preliminary Economic Assessment (PEA) (see Fireweed news release dated May 23, 2018).

A step-out hole at Tom West has been completed to extend the high-grade feeder mineralization to the south.

A step-out hole was completed at Tom East on the down dip extension of a very high grade 2018 hole which returned 21.1% zinc, 13.5% lead and 243 g/t silver over 16.41 metres (see Fireweed news release dated September 20, 2018 for details).

One hole tested Target R where coincident gravity-magnetic highs and a soil anomaly were detected near the camp access road north of the Tom deposits.

Two holes were completed on the Jason North target located immediately north of the large Jason Main Deposit. This target was defined through re-interpretation of historic data and is marked by coincident soil and geophysics anomalies. Despite its location close to Jason Main, Jason North was never before drilled.

The drill has now moved to test the large coincident gravity-magnetic anomaly at Target A after which it will test Target G (see Map 1). See Fireweed news release dated May 21, 2019 for full details of the 2019 exploration plans.

Samples from the first six core holes have been processed and shipped to the laboratory; additional samples will be shipped this week. Drill results will be published as assays are received and interpreted.

Field Exploration

Gravity geophysical crews have surveyed about half of the Fertile Corridor between End Zone and Boundary Zone (see Map 1). Additional gravity surveying may occur this summer as budget and availability of the crew allow.

Geological field work has been focusing on developing additional drill targets at David, Target G and the Fertile Corridor (see Map 1).
