Pinterest LinkedIn Tumblr

Fireweed Metals CORP. (‘Fireweed’ or the ‘Company’) (TSXV: FWZ; OTCQB: FWEDF; FSE: M0G) is pleased to report its best drill intersection from Boundary Zone to date, as well as other spectacular assay results from its 2023 exploration at the Macmillan Pass (‘Macpass’) Project, Yukon, Canada.

Highlights

Best intersection drilled to date at Boundary Zone: hole NB23-028 intersected 143.95 m (50 m true width) grading 14.45% zinc, 1.15% lead, and 60.0 g/t silver, including 28.71 m (10 m true width) grading 25.52% zinc, 1.27% lead, and 91.3 g/t silver. Successful step-out holes continue to increase the extents of known zinc mineralization and demonstrate the high-grade tenor of the Boundary Zone mineralization. Hole NB23-022 intersected 66.11 m (18 m true width) grading 7.13% zinc, 0.97% lead, and 54.8 g/t silver. Assays are pending for 19 remaining drillholes including six more from Boundary Zone, and 11 holes from the Tom deposit, and two holes from the Jason deposit.

CEO Statement

Brandon Macdonald, CEO, stated, ‘I am excited to start the year able to say that we have intersected our best-ever Boundary Zone drill intersection. We stepped out 140 m along strike from NB22-002 and NB23-007 and hit a spectacular intersection in NB23-028, further supporting our interpretation that there is a continuous high-grade feeder zone within the stratiform unit at Boundary Zone. We now have multiple wide and high-grade intersections that highlight the potential for another large zinc system within this exceptional critical minerals project.’

Summary

The mineralization from drill holes in this release primarily comprises stratiform (layer-parallel) and massive (>50% sulphides) sulphides in the western and central areas of Boundary Zone. This mineralization is sub-vertical with sharp margins, occurring from near-surface to at least a depth of 450 m and across a strike length of 550 m. Another stratiform body is present in holes NB23-029 and NB23-029D1 that requires additional drilling to accurately model. We also report intersections of vein and breccia mineralization that occur on both sides of the tabular stratiform sulphide zones. The intersection in hole NB23-028 demonstrates high zinc, lead, and silver grades that are interpreted as forming from higher temperature fluids in association with a feeder system supplying metals to a mineralized system.

Results

The drill holes in this release are located in the central and western areas of Boundary Zone and targeted the stratiform to massive sulphide body with a focus on stepping out from known feeder-style mineralization. NB23-028 intersected a broad, high-grade interval of massive sulphides rich in zinc, lead, and silver that are correlated with this interpreted feeder zone. Stratiform massive sulphides were also intersected in NB23-022 and NB23-029. Stratiform sulphides intersected in NB23-022D1, NB23-029D1 are associated with a separate zone that requires additional drilling and interpretation. Breccia and vein mineralization was also intersected in NB23-028, NB23-029, NB23-029D1 and NB23-031.

Fireweed continues to successfully intersect pyrite-sphalerite-galena as stratiform massive sulphides, laminated mineralization, veins, and breccias in the 2023 step-outs (Photos 1 to 3). Mineralization has been intersected in every step-out hole that has been completed to depth. Assays have been received for 34 Boundary Zone holes (Tables 1 and 2). Brief summaries of mineralized zones within all other 2023 holes are listed in Table 3. Summaries for new drill results reported in this news release are as follows:

Hole NB23-028 intersected a 143.95 m interval of stratiform massive sulphide grading 14.45% zinc, 1.15% lead, and 60.0 g/t silver with an estimated true width of approximately 50 m, including 28.71 m (estimated true width 10 m) of 25.52% zinc, 1.27% lead, and 91.3 g/t silver, further including 10.14 m (estimated true width 3.5 m) of 32.72% zinc, 1.34% lead, and 109.8 g/t silver. Two intervals of vein and breccia style mineralization were also intersected, 19.40 m grading 3.65% zinc and 5.1 g/t silver, and 7.70 m grading 9.95% zinc and 12.7 g/t silver. Hole NB23-022 intersected 66.11 m of stratiform massive sulphide with an estimated true width of 18 m grading 7.13% zinc, 0.97% lead, and 54.8 g/t silver, including 50.08 m (14 m true width) of 7.99% zinc, 1.12% lead, and 61.7 g/t silver. Hole NB23-29D1 is a directionally-cut secondary splay hole from NB23-029 and intersected 20.75 m of stratiform massive sulphide grading 5.20% zinc, 2.05% lead, and 52.6 g/t silver, including 6.50 m of 8.43% zinc, 3.27% lead, and 82.3 g/t silver. This intercept of stratiform mineralization correlates to a separate, distinct body from the primary tabular massive sulphide. NB23-029 intersected a 5.76 m interval of stratiform massive sulphide grading 6.32% zinc, 1.50% lead, and 34.6 g/t silver, as well as an 11.63 m interval of stratiform massive sulphide grading 7.49% zinc, 1.66% lead, and 34.7 g/t silver. Four intervals of vein and breccia style mineralization were also intersected: 27.81 m grading 4.28% zinc and 11.9 g/t silver; 29.18 m grading 2.93% zinc and 4.6 g/t silver; 16.62 m grading 8.74% zinc and 11.1 g/t silver; and 38.40 m grading 3.06% zinc and 8.2 g/t silver. Hole NB23-032 intersected 18.37 m of stratiform massive sulphide with an estimated true width of 8 m grading 4.25% zinc, 0.14% lead, and 12.7 g/t silver, including 4.45 m of 7.55% zinc, 0.19% lead, and 17.3 g/t silver with an estimated true width of 2 m. Hole NB23-031 intersected three zones of breccia and vein style mineralization: 6.50 m grading 7.33% zinc and 14.5 g/t silver; 4.59 m grading 7.33% zinc and 7.7 g/t silver; and 4.27 m grading 7.95% zinc and 3.3 g/t silver. Hole NB23-022D1 is a directional cut off NB23-022 and intersected a 2.50 m interval of sulphide mineralization grading 5.13% zinc, 0.43% lead, and 33.8 g/t silver.

Step-out drilling at Boundary Zone targeting the massive–stratiform zone has resulted in the visual identification of many wide intersections of zinc-lead mineralization with assays pending. The most significant intersections can be seen on Long Section M–M’ and are listed here:

NB23-034 intersected 49 m of stratiform massive sulphide. NB23-035 intersected 15 m of stratiform massive sulphide. NB23-036 intersected 45 m of stratiform massive sulphide. NB23-037 intersected 110 m of feeder-proximal laminated to massive sulphide. NB23-038 intersected 13 m of stratiform massive sulphide.

Out of the 40 holes drilled at Boundary Zone in 2023, 36 were step-out holes that tested the vein mineralization, laminated stratiform mineralization, and massive sulphide zones. 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 geological layer at Boundary Zone, forming an approximately tabular stratiform zone. Step out drilling down-dip intersected abundant galena, supporting the presence of the conceptual feeder zone. The mineralization in the massive stratiform layer extends from surface to at least 450 m down-dip, over 550 m in strike with a variable true thickness that is shown on Long Section M–M’, thinning around the edges and reaching thicknesses of up to 50 m at its widest point.

Extensive vein and breccia mineralization at Boundary Zone occurs both stratigraphically above and below the main stratiform laminated massive sulphide zone. This mineralization forms within a halo approximately 100 m to 150 m wide on both sides of the stratiform laminated zone and is interpreted as a stockwork of randomly oriented veins and breccia zones. Many wide intervals of vein and breccia style sphalerite mineralization have been encountered in 2023 step-out holes and four infill holes (Table 3).

2023 Drill Program

The 2023 program achieved 22,500 m of drilling mostly focused on Boundary, Tom, and Jason zones in addition to five metallurgical drill holes at Mactung (Map 1). Use of directional drilling, in which multiple secondary drill holes are initiated at depth from one primary hole, saved an estimated 1,800 m of drilling compared to traditional drilling of multiple new holes from surface for a total equivalent metreage of 24,300 m in 2023.This was Fireweed’s largest ever program and the biggest drill program in Yukon in 2023.

Data Verification

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 size core (50.5 mm/ 1.99-inch diameter) 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 2023 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. With the exception of samples from NB23-031, 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. Samples from NB23-031 were sent to AGAT labs in Calgary. Samples were crushed, of which 500 g was split and then pulverized to 90% passing 75 microns. Clean crush material was passed through the crusher and clean silica was pulverized between each sample. The pulps were analyzed by Aqua Regia digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-OES/ICP-MS) multi-element analyses (AGAT Code 201-074). All samples were also analyzed for multiple elements by lithium borate fusion and X-ray fluorescence analysis (XRF) finish (AGAT code 11-323). For AGAT samples, silver is reported in this news release by method 201-074, and zinc and lead are reported by 11-323. Bureau Veritas (Vancouver) and AGAT (Calgary) are independent, international ISO/IEC 17025:2017 accredited laboratories.

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 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.

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.

Sphalerite and galena have been identified visually by experienced core logging geologists, and licenced professional geoscientists, and confirmed by portable XRF (X-Ray fluorescence). No absolute visual estimates of mineral abundances or inferences of potential zinc or lead grades have been stated for holes without assay values in this news release.
