Fireweed Commences Gravity Survey at Gayna River Zinc project

Vancouver, British Columbia: FIREWEED METALS CORP. (“Fireweed” or the “Company”) (TSXV: FWZ; OTCQB: FWEDF, formerly known as Fireweed Zinc Ltd.) is pleased to announce that a ground gravity survey has commenced at its recently acquired Gayna River project, Northwest Territories.


  • A ground gravity geophysical survey is targeting high-grade Kipushi-style massive sulphide mineralization.
  • A LiDAR survey will be flown to aid the gravity survey and create a high-resolution Digital Elevation Model for future work.
  • Fireweed has been awarded a government grant to help fund the exploration, significantly reducing the cost of the program.

CEO Statement

Brandon Macdonald, CEO, stated “Back in 2020 when we made a new discovery at Boundary West on our flagship Macmillan Pass project, gravity was a key part of defining the drill target. We are building on the experience that we had in using this exploration tool by applying it to a new search space at our recently acquired Gayna River property where we see the potential to make a new discovery of high-grade massive sulphide mineralization. We are excited to start early-stage work at Gayna River, advancing it in parallel with our portfolio of Critical Minerals projects.”.

Ground Gravity Survey

The ground gravity survey will comprise several grids targeting the areas of highest geological potential. The survey is underway and is being conducted by Aurora Geosciences. A relatively tight station spacing of 50 m is being used, as the search space has already been narrowed down by focusing on specific geological targets. The intent is to use ground gravity to directly detect subsurface density anomalies associated with potential massive sulphide bodies that may lie within approximately 100-200 m of surface.

LiDAR Survey

A state-of-the-art LiDAR survey will be flown using a fixed wing aircraft this summer. The survey will gather data to generate a very high-resolution topographic surface that will be used to assist the gravity survey by allowing the calculation of a high-resolution terrain correction that is necessary for accurate interpretation of the data in areas of rugged relief as well as providing a base map for future exploration work.

Government Grant

Fireweed has been awarded a Mining Incentive Program (MIP) grant from the Government of the Northwest Territories to assist the exploration program. The grant is valued at up to $132,000, significantly reducing the cost of the exploration program for Fireweed.

Gayna River Geology and Mineralization

The Gayna River project is being explored for a potential Kipushi-style target: high-grade zinc-rich massive sulphides. The steep to vertical sides of Neoproterozoic carbonate reefs are being targeted for steeply dipping massive sulphide lenses that may have been missed by previous exploration efforts using vertical holes in historic drill programs. A focused geological mapping and modeling program will refine the search space for this geological environment using high-resolution aerial photographs taken as part of the LiDAR survey, a compilation of historical geological information in 3D, and boots-on-the-ground geological mapping and ground truthing.

About Fireweed Metals Corp. (TSXV: FWZ; OTCQB: FWEDF; FSE:20F): Fireweed Metals is a public mineral exploration company on the leading edge of Critical Minerals project development. The Company has three projects located in northern Canada:

  • Macmillan Pass Zinc-Lead-Silver Project: Fireweed owns 100% of the district-scale 940 km2 Macmillan Pass project in Yukon, Canada, which is host to the Tom and Jason zinc-lead-silver deposits with current Mineral Resources and a PEA economic study (see Fireweed news releases dated 10th January 2018, and 23rd May 2018, respectively, and reports filed on for details) as well as the Boundary Zone, Boundary Zone West, 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 with known showings and significant upside exploration potential. Plans for 2022 include a large drill program toward expanded mineral resources and an updated PEA to include large new zones of mineralization defined since 2018 including Boundary Zones.
  • Mactung Tungsten Project: The Company has a binding Letter of Intent to acquire 100% interest in the 37.6 km2 Mactung Tungsten Project located adjacent to the Macmillan Pass Project. Mactung contains historic resources that make it one of the largest and highest-grade undeveloped tungsten resources in the world. Located in Canada, it is one of the rare large tungsten resources outside of China. Plans for 2022 include due diligence and validation work on historic data in order to support a new mineral resource estimate followed by a Preliminary Economic Study.
  • Gayna River Zinc-Gallium-Germanium Project: Fireweed has 100% of the 128.75 km2 Gayna River project located 180 kilometres north of the Macmillan Pass project. It is host to extensive critical minerals mineralization including zinc, gallium and germanium as well as lead and silver, outlined by 28,000 metres of historic drilling and significant upside potential. Plans for 2022 consist of an airborne LiDAR topography survey, ground geophysics gravity survey and historic data compilation to define drill targets for 2023.
