FIREWEED METALS CORP. reported the final results from the 2023 drilling campaign at its Tom and Jason deposits, Macmillan Pass Project, Yukon, Canada. The deposit is subdivided into several zones, Tom West (or Tom Main zone), Tom East, and Tom Southeast.

Tom North was drilled and re-discovered in 2019, interpreted as a northern extension of Tom West that is not included in the current mineral resource. New drilling at Tom South indicates it is a southern extension of Tom West on the nose of an anticline fold. 2023 drilling tested Tom South with hole TS23-009 and two directional-splay holes TS23-009D1 and TS23-009D2.

Mineralization at Tom is subdivided into geological domains, based on mineralogy and texture: massive sulphide, and pink facies, grey facies, and black facies based on the colour of the sphalerite (zinc) mineralization. Assays have now been received for all 2023 Tom and Jason holes (Tables 1 and 3). Summaries for new drill results reported in this news release are as follows: Hole TS23-009 intersected 17.95 m (14 m est.

true width) of massive and stratiform sulphide grading 11.45% zinc, 5.86% lead, and 126.3 g/t silver, including 6.60 m grading 19.33% zinc, 8.42% lead, and 225.1 g/t silver. Recovery in this mineralized intercept was 64%-below the recovery threshold of 85% typically deemed acceptable at the project, and as a result a secondary hole was drilled as TS23-009D1. Hole TS23-009D2 intersected 18.78 m (est.

true width 9.8 m) of massive and stratiform sulfide grading 9.82% zinc. 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. 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. 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. Bureau Veritas (Vancouver) is an independent, international ISO/IEC 17025:2017 accredited laboratory.

Surface samples from the gold program described in this release were submitted with 5% standards or blanks and 2% duplicates that were reviewed after receipt of assays and approved as acceptable. Samples were sent to The BV preparation laboratory in Whitehorse,Yon, and prepared using the same crushing and pulverizing methods as drill core samples. 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 Tom based on assay results, geological logging, stratigraphic correlation, and bedding measurements from oriented core. The mineralization at Tom is 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.
