(“Fireweed” or the “Company”) ([TSXV: FWZ]( [OTCQB: FWEDF]( formerly Fireweed Zinc Ltd.) is pleased to announce the final set of results from the 2022 drill program at Tom, Macmillan Pass, Yukon, Canada (Map 1), stated as estimated true widths. All assay results from the 2022 program have now been released. Highlights - Multiple wide and high-grade intersections at the Tom deposit. - Hole TS22-009 intersected a true width of 40.6 m at 15.2% zinc, 14.6% lead, and 181.6 g/t silver, including 9 m of 20.7% zinc, 22.4% lead, and 280.0 g/t silver. - Hole TS22-001 intersected a true width of 26.9 m of 9.3% zinc, 5.4% lead, and 61.5 g/t silver, including 8 m of 11.4% zinc, 8.9% lead, and 114.9 g/t silver. - Hole TS22-002 intersected a true width of 9 m of 10.7% zinc, 5.0% lead, and 98.8 g/t silver, including 3.3 m of 18.9% zinc, 14.2% lead, and 324.0 g/t silver. - Many of the 2022 drill holes have demonstrated significantly better grades and/or wider intersections than the current Mineral Resource block model at the same location. CEO Statement Brandon Macdonald, CEO, stated “We are very pleased to close out the reporting of the 2022 results with some phenomenal grades from our Tom deposit. The holes are infill, yet the grades in most of these holes are significantly higher than what has been estimated in our current Mineral Resource for those intersections. We have hit extremely high zinc, lead, and silver grades in intersections of massive sulphides in the feeder zone that are better than anything that we have seen before at Tom West. We see great potential for growth of the Tom resource.”  Tom Drilling Results The drill results shown in Table 1 are the highlights from the Tom zinc-lead-silver deposit (Maps 1 and 2) drill holes described in this news release. Table 2 shows the full Tom deposit 2022 drill results. Table 1: Tom deposit 2022 Drill Results Highlights †: lead is the single largest value contributor to the zinc equivalent calculation in this intersection; *67% recovery; **59% recovery; ***58% recovery. Numbers in the text may differ slightly from numbers in the table due to rounding. True widths in this news release are estimates based on currently available information. See note below for zinc equivalent grade calculation. Unless otherwise noted, zinc is the single largest value contributor to metal value in the zinc equivalent grade calculation for each intersection in this table. The Tom zinc-lead-silver deposit Fireweed’s 100% owned, road-accessible Tom and Jason deposits are some of the world’s largest undeveloped zinc deposits* and host combined current Mineral Resources1 of: 11.21 Mt Indicated Resource at 6.59% zinc, 2.48% lead, and 21.33 g/t silver; and 39.47 Mt Inferred Resource at 5.84% zinc, 3.14% lead, and 38.15 g/t silver. The Tom deposit is subdivided into three distinct zones that have current Mineral Resources: Tom West (Main), Tom East, and Tom Southeast (Map 2). Tom North was drilled by Fireweed in 2019, forms a mineralized zone with no currently defined Mineral Resources, and is located at surface adjacent to Tom West (Map 2, Long Section TA-TA’). Fireweed’s current Mineral Resource was published in early 2018, based on 2017 and earlier drilling only. Boundary Zone, Fireweed’s new discovery and the focus of 2022 drill results reported to date, is located 21 kilometres WNW from the Tom deposit. Tom West Eight infill holes were drilled at Tom West, focusing mostly on the mineralization around the feeder zone within part of Fireweed’s current Mineral Resource. This area is the highest-grade part of the Tom West Mineral Resource and is supported largely by historic drill holes with small diameter core and poor core recovery. Six out of the eight holes drilled at Tom West in 2022 returned grades that are significantly higher than what had been estimated in the current Mineral Resource model for those parts of the deposit. These differences in grade are likely due to better recovery of the higher-grade sections within each intersection in the new, larger diameter drilling compared to the small diameter core drilled in early years which often had poor recoveries. All infill holes demonstrated excellent continuity of mineralization and good grades (see Tables 1 and 2, Long Section TA-TA’). Hole TS22-009 returned spectacularly high grades within an interval of massive sulphide over 40.6 m true width of 15.2% zinc, 14.6% lead, and 181.6 g/t silver, including 20.9 m of 20.7% zinc, 22.4% lead, and 280.0 g/t silver (Table 1). Hole TS22-001 intersected a true width of 26.9 m of 9.3% zinc, 5.4% lead, and 61.5 g/t silver including 12.8 m of 11.4% zinc, 8.9% lead, and 114.9 g/t silver. The intersection comprised laminated sphalerite-galena-barite-pyrite with minor interbedded cherty black mudstones typical of the stratiform mineralization at Tom West. Tom West remains open to expansion in multiple directions and there is additional potential to improve upon historic poor-recovery drilling by completing additional infill drill holes that may yield higher grades of zinc, lead, and silver with improved recovery (Long Section TA-TA’). Tom East Hole TS22-002 was drilled as an infill hole at Tom East, not only confirming the high grades previously known at Tom East, but providing an intersection with grades higher than currently modeled in an equivalent intersection within that part of the current Tom East Mineral Resource model. The estimated true width at the intersection is 16.9 m that returned 10.7% zinc, 5.0% lead, and 98.8 g/t silver including 3.3 m of 18.9% zinc, 14.2% lead, and 324.0 g/t silver, highlighting some of the very high grades present at Tom East.

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 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 results tables. 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 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’s 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. True widths are estimated by measuring perpendicular to strike within the short axis of an approximately tabular shaped wireframe that has been constructed in 3D around the mineralized zone at Tom West based on assay results, geological logging, and bedding measurements from oriented core. The mineralization at the Tom deposit is 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. Zinc Equivalent Calculation The use of zinc equivalent (ZnEq.) grades in this news release follows the calculation described in Fireweed 2018 Technical Reports1,2, and detailed below: ZnEq. = (x + y + z + a)/16.16 where x = 16.16*zinc(%); y = 16.08*lead(%); z = (0.05853*silver(g/t))-(0.6146*zinc(%)); and a = (0.447*silver(g/t))-(0.3607*lead(%)). Terms z and a are only included in the calculation of ZnEq. when positive. This ZnEq. calculation assumes metal prices of US$1.17/lb zinc, US$0.99/lb lead, and US$16.95/oz silver. Metal recovery assumptions were: 79% for zinc, 82% for lead, and 85% for silver (whereby 12% would be recovered from a zinc concentrate and 73% would be recovered from a lead concentrate). The ZnEq. calculation includes estimated factors for: metallurgical recoveries, assumed metal prices, and smelter terms including payable factors, treatment charges, and refining charges. The calculation assumes an exchange rate of US$1 = C$1.24.
