Fireweed Drills 105 m of 8.4% Zinc and 12.1 g/t Silver Including 12.75 m of 24.9% Zinc and 41.7 g/t Silver
VANCOUVER, British Columbia, Feb. 27, 2023 (GLOBE NEWSWIRE) — FIREWEED METALS CORP. (“Fireweed” or the “Company”) (TSXV: FWZ; OTCQB: FWEDF, formerly Fireweed Zinc Ltd.) is pleased to announce additional results from the 2022 drill program at Boundary Zone, Macmillan Pass zinc-lead-silver project, Yukon, Canada (Map 1).
- A high grade and wide intersection of zinc mineralization in NB22-021 for 105 metres (m) of 8.4% zinc and 12.1 g/t silver starting from surface.
- A new stratiform zone in NB22-018 returned 8 m of 11.5% zinc, 1.7% lead, and 61 g/t silver.
- All holes completed hit zinc mineralization.
- Results from the last five (5) holes from Boundary Zone and nine (9) holes from the Tom deposit are pending.
Brandon Macdonald, CEO, stated “Boundary Main Zone continues to impress with not only the wide tenor of mineralization but also with high-grade intervals. Equally important is the discovery of a new stratiform zone where we expect to see good continuity of mineralization consistent with similar zones at Tom, Jason and Boundary West. With a large drill campaign planned for the summer we are looking forward to testing the extents of mineralization in these zones and growing our already world-class metal endowment.”
Boundary Zone Drilling Results
The following drill results (Tables 1 and 2) are from seven (7) drill holes located at Boundary Zone (Maps 1 and 2), all within the Boundary Main area. The last results from five (5) holes from Boundary Main and nine (9) holes from the Tom zinc-lead-silver deposit 2022 drill program are still pending.
Table 1: Boundary Zone 2022 Drill Result Highlights from this News Release.
*Intersected thicknesses, not true thicknesses, are stated for all intersections in Table 1. Due to the early stage of drilling, true thicknesses cannot be accurately stated for these holes. Values in this table may differ slightly from the text due to rounding.
NB22-018, NB22-020 and NB22-021
These three (3) holes were collared from the same pad, forming a fan of holes that intersected high grade sphalerite-pyrite vein and breccia mineralization from surface to depths of up to ~100 m in the hangingwall of the Boundary Main Fault (Cross Section F-F’ and Map 2). Hole NB22-021 intersected 105 m of 8.4% zinc, and 12.1 g/t silver including both an intersection from surface grading 13.2% zinc and 16.5 g/t silver over 27.8 m and an intersection of spectacularly high-grade zinc mineralization grading 24.9% zinc and 41.7 g/t over 12.75 m including 3.83 m of 40.0% zinc and 62.6 g/t silver (see Image 1 and Tables 1 and 2). Holes NB22-018 and NB22-020 also intersected wide intervals of zinc mineralization in the near surface: 141.8 m of 2.9% zinc, 0.5% lead, and 12.7 g/t silver, and 90.7 m of 4.7% zinc, and 6.7 g/t silver, respectively.
Holes NB22-018 and NB22-020 penetrated the Boundary Main fault and intersected a new zone of stratiform zinc mineralization in black carbonaceous mudstones and diamictites comprising laminated, semi-massive, and massive sphalerite-pyrite grading 11.5% zinc, 1.7% lead, and 61.0 g/t silver over 8 m in NB22-018 and 5.0% zinc, 2.1% lead, and 37.9 g/t silver over 5 m in NB22-020 (see Cross Section F-F’, and Tables 1 and 2). This stratiform zone is interpreted to correlate stratigraphically with the Tom-Jason deposits. The stratiform zone is correlated spatially to zinc-lead mineralization in surrounding holes: in several holes to the east, it appears to be less mineralized and is interpreted as the fringes of the zone; whereas to the west, it appears to be significantly better mineralized in NB22-022 and NB22-023 and is interpreted to be the direction towards the feeder.
NB22-009 and NB22-011
These two (2) holes were collared from the same pad and include wide intervals of vein-hosted mineralization near surface at Boundary Main: NB22-009 returned 115.8 m of 3.6% zinc and 5.4 g/t silver, including 18.5 m of 7.8% zinc and 12.0 g/t silver from a downhole depth of 18 m; NB22-011 intersected 23 m of 7.6% zinc and 10.1 g/t silver including 10.6 m of 12.3% zinc and 15.2 g/t silver (see Cross Section G-G’, Map 2 and Tables 1 and 2).
Hole NB22-011 intersected zinc mineralization in the footwall of the Boundary Main Fault in volcaniclastic rocks for 26 m grading 6.6% zinc and 12.4 g/t silver including 6.5 m of 16.0% zinc and 20.6 g/t silver. This intersection represents a 60 m step out from similar mineralization in holes to the west. Drilling was unable to advance through the fault in hole NB22-009 due to adverse drilling conditions and the target in the footwall remains untested at this location.
NB22-010 and NB22-013
These two (2) holes were collared from the same pad as infill holes at Boundary Main (see Cross Section G-G’ and Map 2). Both holes successfully intersected sphalerite vein mineralization in the hangingwall of the Boundary Main fault. Hole NB22-010 intersected 39.7 m of 5.7% zinc and 11.2 g/t silver, including some higher-grade veins: 4 m of 13.5% zinc, 2.9 m of 12.8% zinc, 3.5 m of 10.1% zinc, and 3.7 m of 11.1% zinc (Table 2). Hole NB22-013 intersected 49.3 m of 3.4% zinc and 12.0 g/t silver including 10.2 m of 10.2% zinc and 19.0 g/t silver.
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 (61.1 mm / 2.406-inch diameter) or NQ2 size core (50.5 mm / 1.99-inch diameter) 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 2 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 (4) 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, British Columbia 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.
