Defense Metals Resource Upgrade Drilling Intersects 2.33% TREO over 153 Metres at the Wicheeda Rare Earth Project

VANCOUVER, BC, Oct. 8, 2026 /CNW/ -- Defense Metals Corp. ("Defense Metals" or the "Company"; (TSXV: DEFN) (OTCQB: DFMTF) (FSE: 35D) is pleased to announce assay results for a final ten core drill holes, totalling 1,702 metres (m), completed during spring 2026 at its 100% owned Wicheeda Rare Earth Project (the "Wicheeda Project") located near Prince George, Canada.

Robin Jones, Defense Metals VP Projects, commented: "We're exceptionally pleased that all ten drill holes reported in today's news release intersected significant widths of high to moderate grade Rare Earth Element mineralization within the pit confines defined by the 2025 Preliminary Feasibility Study (PFS) and are expected to contribute positively to a resource classification uplift."

The resource infill drilling was designed to upgrade a significant tonnage of inferred resources, constrained within the limits of the current Wicheeda Project Preliminary-Feasibility Study ("PFS") ultimate pit design, to an indicated or better category (see Defense Metals news release dated February 18, 2025). With the receipt of final 2026 resource upgrade drilling assays presented in this news release the Company intends to update its geological and mineral resource block models to quantify the potential changes to Wicheeda Project mineral resource estimate (MRE) because of this new drilling.

Highlights of the 2026 Wicheeda Deposit inferred resource upgrade drilling:

• Of the 19 inferred resource upgrade drill holes totalling 2,887 m drill assays on average were 87% of predicted inferred block model grades
  
  
• Drill hole WI26-104, which returned the highest-grade x width intercept of the 2026 drill campaign and yielded drill assays 34% higher than predicted inferred block model grades along the southern pit wall
  
  
• In the western pit wall area 6 of 7 drill holes returned assays that exceeded predicted inferred block model grades with an average increase of 24% suggesting further opportunities for both resource upgrading and expansion in this area with additional drilling

Details of Resource Upgrade Effectiveness

Of the 19 inferred resource upgrade drill holes totalling 2,887 m drill assays on average were 87% of predicted inferred block model grades¹. Defense Metals highly is encouraged by the level of accuracy of the Company's block and geological models, given that inferred resources are based on limited geological evidence and sampling, sufficient to imply but not verify geological and grade or quality continuity.

Within the western pit wall area 6 of 7 drill holes returned assays that exceeded predicted inferred block model grades with an average increase of 24%. These drill holes intersected mineralized intercepts that were generally higher grade than predicted and include a higher proportion of higher-grade dolomite carbonatite rocks than predicted by the PFS geological model, suggesting further opportunities for both resource upgrading and expansion in this area with additional drilling.

Within the southern pit area drill holes returned somewhat lower assays, 76% of predicted inferred block model grades, due to a local 20 m northward shift of the mineralized contact. However, notably drill hole WI26-104 returned the highest-grade x width intercept of the 2026 drill campaign and yielded drill assays 34% higher than predicted inferred block model grades.

Drill Hole Assay Details

The resource upgrade drill holes targeted two specific areas hosting the majority of in pit inferred resources. The results released today include two holes totalling 322 metres targeting the southern PFS ultimate pit wall; in addition to eight holes totalling 1,380 metres along the western pit wall (in addition remaining assay results for WI26-102 see Defense Metals Corp. News release dated August 31, 2026).

South pit wall drill hole highlights include:

Drill holes WI26-102 and WI26-103, drilling outward from inside the Wicheeda Deposit. WI26-102 collared into REE mineralized dolomite carbonatite yielded a higher-grade intercept returning 3.25% TREO over 34.3 m, within a broader interval averaging 2.26% TREO over 91.4 m. Hole WI26-103 drilled at stepper dip on the same section returned 2.57% TREO over 87.7 m within a broader mineralized intersect averaging 2.13% TREO over 115.5 m (Table 1, and Figure 1).

Drill hole WI26-104 drilling to the southwest and cutting obliquely across the southern margin of the Wicheeda Deposit yielded the most significant grade x width intercept of the entire resource upgrade campaign intersecting a broad interval of mineralized dolomite carbonatite from surface returning 2.33% TREO over 153.2 m (Figure 2).

West pit wall highlights include:

West pit wall resource upgrade drilling targeted inferred resources via a fan of seven drill holes collared from a single setup along southwest to northwest azimuths. Drill holes WI26-105 through WI26-111 all intersected mineralized mixed dolomite carbonatite, xenolithic dolomite carbonatite and syenite intervals beneath variable overburden at low elevation along western margin of the Wicheeda Deposit (Figure 3).

A complete list of significant intercepts is presented in Table 1 below; with notable highlights including:

• WI26-109 returning 1.51% TREO over 66.8 m; within a broader interval grading 1.00% TREO over 134.4 m;
• WI26-110 grading 2.10% TREO over 54 m, within a broader interval averaging 1.21% TREO over 182.1 m;
• WI26-111 cutting 1.89% TREO over 122.55 m

• 4 holes (702 m) waste rock geochemical drilling

Methodology and Quality Assurance/Quality Control

The analytical work reported on herein was performed by ALS Canada Ltd. ("ALS") at their Langley (sample preparation) and Vancouver (ICP-MS fusion), B.C. facilities. ALS is an ISO-IEC 17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory and is independent of the Defense Metals and the Qualified Person ("QP"). Drill core samples were subject to crushing at a minimum of 70% passing 2 mm, followed by pulverizing of a 250-gram split to 85% passing 75 microns. A 0.1-gram sample pulp was then subject to multi-element ICP-MS analysis via lithium-borate fusion to determine individual REE content (ME-MS81h). Defense Metals follows industry standard procedures for the work carried out on the Wicheeda Project, with a quality assurance/quality control ("QA/QC") program. Blank, duplicate, and standard samples were inserted into the sample sequence sent to the laboratory for analysis. The QP and Defense Metals detected no significant QA/QC issues during review of the data.

Drill hole assay and inferred block model grades were compared by flagging drill database assay intervals and inferred resource blocks along the trace of each drill hole. The drilled length, number of samples and assay results were then compared to the predicted block model grades as TREO and individual REE on a grade x width basis to generate percentage increase or decrease.
