Fireweed Zinc Ltd (CVE:FWZ) (OTCMKTS:FWEDF) (FRA:20F) has posted more drill results from its flagship Macmillan Pass project in Yukon - this time from a reverse circulation (RC) program at the Tom and Jason deposits.
The aim was to assess the potential of RC drilling as a lower-cost alternative to diamond drilling for upgrading resources at shallow depths and the holes were sunk as infill and twin holes at the Tom and Jason deposits. A step-out was also drilled at Tom North.

"Improvements in grade with modern drilling methods have been seen in 2018 at Tom West, in 2019 at Tom North and again here in 2020, showing significant grade upside potential for infill drilling," said Brandon Macdonald, CEO.
"The RC program tested areas with some of the most challenging drilling conditions on the property and yet still delivered excellent results at a lower cost than diamond drilling.
"We see potential to use RC drilling during infill drill programs to reduce the cost of upgrading mineral resources at shallow depths, particularly at Boundary Zone where mineralization occurs at surface and is hosted by much more competent rocks where drilling conditions are much more favourable. The successful step-out hole shows that the project continues to grow at Tom as we advance new discoveries at Boundary Zone," he added.
The step-out at Tom North hit an interval of 8.1 metres (m) true thickness of 5.92% zinc, 0.25% lead, and 1.7 grams per ton (g/t) silver from 88.39m depth.
The infill hole at Tom West intersected 8.2m true thickness of 11% zinc, 8.74% lead, and 19.6 g/t silver starting from a depth of 38.10m.
Fireweed Zinc is advancing its district-scale 940 sq km Macmillan Pass Project in Yukon, Canada, which is host to the Tom, Jason, Boundary Zone, and End Zone zinc-lead-silver deposits.
Tom and Jason already comprise a combined resource of 11.21 million tonnes (Mt) of higher confidence indicated resources at 9.61% zinc equivalent (ZnEq) and 6.59% zinc, 2.48% lead, 21.33 grams per ton (g/t) silver, and there is potential to expand this further.
