VANCOUVER, British Columbia, Jan. 31, 2023 (GLOBE NEWSWIRE) -- FIREWEED METALS CORP. (“Fireweed” or the “Company”) (TSXV: FWZ; OTCQB: FWEDF, formerly Fireweed Zinc Ltd.) is pleased to announce further results from the 2022 drill program at Macmillan Pass, Yukon, Canada (Map 1).
- At Boundary Main step-out drillhole NB22-006 intersected 12.5 m of 11.17% zinc including 6.2 m of 15.84% zinc.
- A new laminated zone in hole NB22-008 returned 14.55% zinc, 1.50% lead, and 28.8 g/t silver over 2.65 m.
- Copper-zinc mineralization was intersected in NB22-006 over 10.5 m grading 0.45% copper and 2.32% zinc.
- Assay results from 24 additional drill holes at Boundary and Tom Zones are pending.
Brandon Macdonald, CEO, stated, “Drilling continues to extend the Boundary Zones with high-grade step-out drill results, including the discovery of a new stratiform zone. The zones remain open along trend and to depth for further extension. Many additional 2022 drill results are pending and we have started planning the biggest drill program in the history of the project for 2023.”
New Boundary Drillholes Results
Laminated sphalerite-galena-barite-pyrite mineralization was intersected in NB22-008 within only 35 m from surface and occurs within the same late-Devonian stratigraphy that hosts the Tom and Jason deposits. This zone graded 8.08% zinc, 0.82% lead, and 17.8 g/t silver over 5.58 m, containing a higher grade 2.65 m interval of 14.55% zinc, 1.50% lead and 28.8 g/t silver (Table 1). This represents a new discovery of a high-grade laminated zone at Boundary Main and remains open to the north and west.
Deeper in NB22-008, a broad zone of sphalerite mineralization was intersected, grading 3.32% zinc over 30.68 m (including higher grade intervals listed in Table 1), representing a ~65 m step-out down-dip from the historic Cominco hole NB91-25 (Map 2). This zone comprised replacement of matrix and some clasts by pyrite and red sphalerite in coarse clastic rocks and breccias cemented by sphalerite-pyrite with minor sphalerite-quartz veins. The textures in this step out intersection are typical of the zinc mineralization at Boundary Main.
This hole intersected several narrow (2.84 m to 4.7 m wide) intervals of stockwork sphalerite-siderite veins grading 4.20% to 5.55% zinc (Table 1) within a sequence of coarse volcaniclastic rocks and conglomerates, typical of mineralization at Boundary Main. These intersections are 30 m to 40 m step-outs up-dip from mineralization in historic Cominco hole NB91-25 (Map 2).
Deeper in NB22-005 an 18.4 m intersection of 2.84% zinc was made in a sequence of black mudstones and lapillistones of the Road River Group comprising many thin red sphalerite-quartz-siderite veins and selective replacement of lapilli by red sphalerite. This intersection is a ~45 m step-out from similar mineralization intersected in 2021 Fireweed drillhole NB21-010.
This hole intersected matrix and clast replacement sphalerite mineralization and sphalerite vein mineralization in several wide intervals typical of the style seen at Boundary Main (Table 1). A higher-grade portion of one of these intervals graded 11.17% zinc over 12.5 m including 6.22 m of 15.84% zinc. Hole NB22-006 is a step-out hole, stepping-out 55 m to 70 m away from zinc mineralization in historic Cominco drillhole NB90-20 (Map 2, Cross Section E-E’).
In hole NB22-006, copper-zinc mineralization was intersected over 10.5 m at 0.45% copper and 2.32% zinc within semi-massive pyrite replacing diamictite clasts and matrix. This intersection is 145 m along strike from the intersection of 1.54% copper and 5.42% zinc over 2.00 m reported from 2021 drillhole NB21-005 (see Fireweed news release dated November 18, 2021) and it is unclear whether there is any continuity between these intersections.

Zones: BM= Boundary Main; BW= Boundary West.
*Intersected thicknesses, not true thicknesses, are stated for all intersections in Table 1. Most intersections in Table 1 are vein stockwork or replacement styles of mineralization and have undetermined true thicknesses. The laminated mineralization in NB22-008, 40.92 m to 46.50 m is assumed to be stratiform and true thickness is estimated to be approximately 30% to 85% of intersected thickness, based on bedding angles to core axis in and around the mineralized intersection.
Note – an interval of core in NB22-006 from 232.82 m to 255.87 m and an interval from 57.0 m to 66.87 m in hole NB22-008 were not assayed as these intervals were lost to a windstorm that up-ended several core tables, spilling the core on the ground prior to logging and sampling.
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 HQ3 (split tube) size core (61.1mm / 2.406-inch diameter) (drill hole NB22-008) and NQ2 size core (50.5 mm/ 1.99-inch diameter) (drill holes NB22-005 and NB22-006) with recoveries typically above 85% unless otherwise noted in the table of results. After drilling, core was cleaned, scanned with a core scanning machine, 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 2022 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 and copper are 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.
