Fireweed Drills 6.9% Zinc, 5.0% Lead, and 48.7 g/t Silver over 11.7 m True Width at Tom East

By Umair Khan - January 13, 2022

VANCOUVER, British Columbia, Jan. 12, 2022 (GLOBE NEWSWIRE) — FIREWEED ZINC LTD. (“Fireweed” or the “Company”) (TSXV: FWZ; OTCQB: FWEDF) is pleased to announce further assay results from the 2021 drilling program at the Macmillan Pass project, Yukon, Canada where an infill hole at Tom East (see Maps 1 & 2) encountered high-grade laminated mineralization.


  • Hole TS21-001 intersected 10.41% zinc, 11.58% lead, and 149.9 g/t silver over 7.99 m (true width 2.46 m) within a broader interval of 6.92% zinc, 5.03% lead, and 48.7 g/t silver over 37.99 m (11.70 m true width).
  • Tom East is the highest-grade deposit on the property and remains open for expansion.
  • Assay results from the last two holes at Boundary West are pending.

CEO Statement

Brandon Macdonald, CEO, stated “Tom East continues to deliver high-grade results consistent with previous drilling in the area. As we continue to develop the resource, it is highly encouraging that we continue to intersect these wide high-grade zones. These results will be used to guide future drilling, enhance existing geological models, and upgrade the resource. In the coming weeks, we look forward to more drill results from the last two holes at Boundary West.”

Tom East Drilling Results

Hole TS21-001 was drilled at Tom East, a high-grade zone within the Tom deposits area (Maps 1 and 2). Tom East hosts a current Mineral Resource of 0.81 Mt at 8.74% zinc, 8.62% lead, and 110.0 g/t silver Indicated Resource in addition to 1.68 Mt at 9.86% zinc, 12.86% lead and 170.0 g/t silver Inferred Resource (see Fireweed news releases dated January 10th, 2018, and reports filed on for details). The Tom East Zone is hosted within and around the hinge of a tight north-plunging syncline fold containing stratiform laminated sphalerite, galena, and barite mineralization. The mineralization is hosted by late-Devonian diamictite and carbonaceous mudstones in the Portrait Lake Formation (Earn Group).

The mineralization comprises laminated to massive sulphides, predominantly consisting of thinly laminated sphalerite, galena, barite, and chert. Soft-sediment deformation has created chaotic laminae (Photo 1) further distorted by regional folding. Mineralization is consistent with other intervals encountered within the Tom East and Tom West zones. Geological information from this hole will inform ongoing geological models for resource expansion.

Notes on sampling, assaying, and data aggregation:

The diamond drill core logging and sampling program was carried out under a rigorous quality assurance / quality control program using industry best practices. Drill intersections in this release are all HQ3 (split tube) size core (61.1mm / 2.4-inch diameter) with recoveries typically above 85% unless otherwise noted in the table of results. After drilling, core was logged for geology, structure, and geotechnical characteristics, then marked for sampling and photographed on site. The cores for analyses were marked for sampling based on geological intervals with individual samples 1.5 m or less in length. Drill core was cut lengthwise in half with a core saw; half-core was sent for assays reported in this news release, and the other half is stored on site for reference. Bulk density was determined on site for the entire length of each sample assayed by measurement of mass in air and mass in water. Sample duplicate bulk density determinations and in-house bulk density standard determinations were each made at a rate of 5%. Since 2017, four in-house bulk density standards (mineralized drill core from the Tom deposit that span a range of densities) have been used and show an acceptable long-term precision. Certified standard masses are used to calibrate the scale balance used for bulk density determinations.

A total of 5% assay standards or blanks and 5% core duplicates are included in the sample stream as a quality control measure and are reviewed after analyses are received. Standards and blanks in 2021 drill results to date have been approved as acceptable. Duplicate data add to the long-term estimates of precision for assay data on the project and precision for drill results reported is deemed to be within acceptable levels. Samples were sent to the Bureau Veritas preparation laboratory in Whitehorse, Yukon, where the samples were crushed and a 500 g split was sent to the Bureau Veritas laboratory in Vancouver, B.C to be pulverized to 85% passing 200 mesh size pulps. Clean crush material was passed through the crusher and clean silica was pulverized between each sample. The pulps were analyzed by 1:1:1 Aqua Regia digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-ES/ICP-MS) multi-element analyses (BV Code AQ270). All samples were also analyzed for multiple elements by lithium borate fusion and X-ray fluorescence analysis (XRF) finish (BV Code LF725). Over-limit Pb (>25.0%) and Zn (>24.0%) were analyzed by lithium borate fusion with XRF finish (BV Code LF726). Silver is reported in this news release by method AQ270, and zinc and lead are reported by LF725 or LF726. Bureau Veritas (Vancouver) is an independent, international ISO/IEC 17025:2005 accredited laboratory.

Results in this news release are length and bulk-density weighted averages as would be used in a Mineral Resource estimate. Readers are cautioned that in Fireweed news releases prior to 2020, only length weighted assay averages were reported which may result in slightly lower (under-reported) average values. Length and bulk-density weighted averages have been reported as these most accurately represent the average metal-content of the intersections.
