Fireweed Grows Boundary Zone, Intersecting 92.15 m of 8.61% Zinc, 2.60% Lead, and 42.7 g/t Silver, Including 11.21 m of 21.40% Zinc, 6.66% Lead, and 107.6 g/t Silver at the Macpass Project, by @GlobeNewswire

VANCOUVER, British Columbia, Sept. 26, 2024 (GLOBE NEWSWIRE) -- FIREWEED METALS CORP. (“Fireweed” or the “Company”) (TSXV: FWZ; OTCQX: FWEDF) is pleased to report the initial results of the 2024 drill campaign, announce the appointment of Graham Richardson as the Company’s CFO, and provide an update on the exploration program at its Macpass Project, Yukon, Canada.

Highlights

Hole NB24-001 intersected 92.15 m of 8.61% zinc, 2.60% lead, and 42.7 g/t silver (37 m true width), including 11.21 m of 21.40% zinc, 6.66% lead, and 107.6 g/t silver (4.5 m true width).
Vein and replacement mineralization intersected in NB24-008 is a 160 m step out to the west from previous drilling, while the stratiform massive sulphide intercepted in NB24-001 is a 65 m intercept west of previous drilling.
Expansion of the drill program to over 16,000 m across Boundary Zone, Tom, Jason, and exploration targets.
Ground and airborne based geochemical and geophysical surveys have been completed across the Macpass district.

CEO Statement

Peter Hemstead, Interim President and CEO, stated, “We are excited to report the first results of the season with an excellent intercept on the far-western side of Boundary Zone. The style of mineralization associated with this high-grade result indicates there is potential for a feeder system within this part of the deposit, and an extension of the known mineralization to the west, 45 m beyond the existing MRE pit shell. We are pleased to expand the drill program to over 16,000 m and are looking forward to the additional results from Boundary Zone, Tom, and Jason, as well as the outcomes from the large regional exploration program that we embarked upon this year along the Macpass prospective corridor.”

Summary
The drill holes in this release comprise intervals of vein and replacement style mineralization as well as massive (>50% sulphides) to stratiform (layer-parallel) sulphides on the extreme western side of Boundary Zone. Massive sulphide mineralization at Boundary is split into three primary domains based on location and geochemistry: BZFL (Boundary Zone Fuller Lake), BZUZ (Boundary Zone Upper Zone) and BZPZ (Boundary Zone Prime Zone). This wide intersection of massive sulphides in NB24-001, which expands the known mineralization to the west, represents the broadest high-grade intercept of mineralization seen to date in BZUZ, and the high silver and lead grades are indicative of feeder style mineralization seen in the thickest and highest-grade portions of the Prime Zone.

Results
Drill holes in this release are located on the western side of Boundary Zone and were targeting stratiform to massive sulphides with a focus on extending mineralized domains to the west and down dip of the recently published Mineral Resource Estimate (see Map 2 and Figure 1). Both holes NB24-001 and NB24-008 intersected vein and replacement style mineralization in the upper portions of the hole, with NB24-001 intersecting a broad zone of feeder-style massive to stratiform sulphides rich in sphalerite and galena.

Fireweed successfully intersected stratiform and massive sulphides in both NB24-001 and NB24-008 (Photos 1 and 2). Summaries of the intercepts from these two holes are as follows:

Hole NB24-001 intersected 92.15 m (estimated true width of 37 m) of laminated and massive sulphides grading 8.61% zinc, 2.60% lead, and 42.7 g/t silver, including 11.21 m (estimated true width 4.5 m) of 21.40% zinc, 6.66% lead, and 107.6 g/t silver, and a near surface interval of breccia and vein mineralization 21.46 m in width grading 2.25% zinc, and 4.7 g/t silver.
Hole NB24-008 intersected 3.05 m of stratiform to semi-massive sulphide grading 2.23% zinc, 6.16% lead, and 80.3 g/t silver, as well as a near surface interval of breccia and vein mineralization 10.37 m in width grading 2.86% zinc, and 3.3 g/t silver as well as a second interval of replacement style mineralization 34.00 m in width grading 1.56% zinc, 0.59% lead, and 8.3 g/t silver.

See Tables 1 to 4, Cross Section T–T’ and Map 2 below for further details.

NB24-001 and NB24-008 are step-out holes that tested the vein and breccia mineralization, laminated stratiform mineralization, and massive sulphide zones on the far western portion of Boundary Zone stepping vein and replacement mineralization 160 m west of previous intercepts and intersecting massive sulphides 65 m west of previous intercepts. The geometry and stratigraphic sequence intersected in these holes continue to support the idea that the laminated and massive sulphide mineralization are part of the same discrete geological layers at Boundary Zone, forming tabular stratiform zones. Drilling prior to 2024 identified a massive sulphide domain referred to as BZPZ (Boundary Zone Prime Zone) extending from surface to at least 450 m down-dip, over 550 m in strike with a variable true thickness thinning around the edges and reaching thicknesses of up to 50 m at its widest point. The zone remains open for extension along strike and at depth. Step-out drilling along strike from previous intersections in a second zone, stratigraphically above BZPZ designated as BZUZ, intersected abundant sphalerite and galena, supporting the presence of the conceptual feeder zone.

Extensive vein and breccia mineralization at Boundary Zone occurs both stratigraphically above and below the main stratiform laminated massive sulphide zones. This mineralization forms within a halo approximately 100 m to 150 m wide on both sides of the stratiform laminated zones and is interpreted as a stockwork of randomly oriented veins and breccia zones that are contained within broadly stratiform bodies. Many wide intervals of vein and breccia style sphalerite mineralization were encountered in 2023 step-out holes and were subsequently captured within the 2024 resource².

2024 Drill Program
The 2024 drill program achieved over 16,000 m of drilling focused on Boundary Zone, Tom, Jason, and regional exploration targets (Map 1). Similar to 2023, the 2024 program has utilized directional drilling to save an estimated 1,727 m of drilling compared to traditional drilling of multiple new holes from surface, for an approximate equivalent metreage of 17,740 in 2024 to date.

As part of this season’s program, 49 step-out and exploration drill holes have been completed and results for 2 have been released. Twenty-six holes were drilled at Boundary Zone, 6 at Tom South, 2 at Jason, and 15 at exploration targets around the property.

The assay results for additional completed drill holes will be released as they are received, analyzed and confirmed by the Company.

Regional Exploration
In addition to the significant drill program at Macpass in 2024, a comprehensive regional exploration program was conducted to provide extensive coverage of geochemical (soil sampling and rock sampling) and geophysical data (ground-based gravity survey, airborne Versatile Time Domain Electromagnetic (VTEM) survey along the prospective corridor and supplementary LiDAR and Orthophoto surveys to provide complete coverage of the entire 977 km² Macpass district.

Data Verification and QA/QC
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 NQ2 and HQ size core (50.5 mm/ 1.99-inch diameter, 63.5 mm/ 2.5-inch) with recoveries typically above 85% unless otherwise noted in the results tables. After drilling, core was cleaned, logged for geology, structure, and geotechnical characteristics, then marked for sampling and photographed on site. Certain cores were selected for core scanning. The cores for analyses were marked for sampling based on geological intervals with individual samples 2 m or less in length, with 1 m samples within mineralized zones. 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 assay sample 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 2024 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 (BV) preparation laboratory in Whitehorse, Yukon, where the samples were crushed and a 500 g split was sent to the BV 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 lead (>25.0%) and zinc (>24.0%) were analyzed by lithium borate fusion with XRF finish (BV Code LF726). For BV samples, 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 17025:2017 accredited laboratory.

Assay values may appear rounded to one decimal place but are given in full in Table 1, Table 2, and Cross Sections where zinc and lead grades are reported to two decimal places.

Results in this news release are selected from composites with selection parameters based on a 1.41% zinc equivalent cut off (ZnEq*) with elemental abundances within the composite presented length and bulk-density weighted averages as would be used in a Mineral Resource estimate. Length and bulk-density weighted averages have been reported as these most accurately represent the average metal-content of the intersections. ZnEq is not reported and is used solely as a composite selection criterion.

True widths for primary intervals are estimated by measuring perpendicular to strike within the short axis of a stratiform wireframe that has been constructed in 3D around the mineralized intercepts at Boundary Zone based on assay results, geological logging, stratigraphic correlation, and bedding measurements from oriented core. The massive sulphide mineralization and laminated mineralization at Boundary Zone are mostly stratiform (oriented parallel to bedding), therefore the true width, or thickness, of the zone is estimated perpendicular to both the strike and dip direction of bedding. Vein and breccia mineralization at Boundary Zone are interpreted to be stockworks with variable shapes and true widths cannot be accurately estimated, therefore only intersected widths are reported, and true widths are marked as N/A in the assay tables. True widths are rounded to the nearest metre for widths over 10 m and to the nearest 0.1 m for widths less than 10 m, as this better reflects the precision of the estimates. True widths should be regarded as approximate as these are derived from an estimation that uses a preliminary interpretation of the geological model. True widths for nested intervals (marked as “Including” in results tables) are estimated using a ratio of included to primary intersected widths to attribute appropriate portions of the true width of the primary interval to the nested intervals.

This news release also contains references to estimates of mineral resources. The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may require re-estimation based on, among other things: (i) fluctuations in the price of zinc and other metals; (ii) results of drilling; (iii) results of metallurgical testing, process and other studies; (iv) changes to proposed mine plans; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licenses.
