Star Metro - Apex Extends Trinity Zone in West Step-out Drilling With 2.52% REO Over 223.3 m and 2.49% REO Over 123.3 m at Rift

VANCOUVER, BC / ACCESS Newswire / November 10, 2026 / Apex Critical Metals Corp. ("Apex" or the "Company") (NASDAQ:APXC)(CSE:APXC)(OTCQX:APXCF)(FWB:KL9)(Euronext Access Paris:MLAPX), a mineral exploration company focused on advancing its strategic 100%-controlled Rift Rare Earth Project within the Elk Creek Carbonatite Complex in southeastern Nebraska, U.S.A., is pleased to report the assay results from drillholes RIFT26-025 through RIFT26-028.

Sean Charland, CEO of Apex Critical Metals, commented: "The results from RIFT26-025 through RIFT26-028 continue to demonstrate the significant grade and scale profile with the Trinity Zone extending to the west and northwest and remaining open for expansion. Hole RIFT26-026 alone intersected more than 200 metres of high-grade rare-earth mineralization. With drilling ongoing and an MRE planned by the end of Q1/2027, we continue to demonstrate the potential for our Rift Project to emerge as a strategic contributor to the domestic and international rare earth supply chains."

The Company continues to define the Trinity Zone along two primary E-W drill fences with RIFT26-026 and RIFT26-025 drilled as western step-outs on the northern (A-A') and southern (B-B') primary E-W drill fences, approximately 90 m and 85 m west of RIFT26-024 and RIFT26-019, respectively (Figures 1-3). RIFT26-027 and RIFT26-028, reported herein, also extend the mineralized footprint of the Trinity Zone an additional 100 m to the northwest of drillhole fence A-A' (see Figure 1 and news release dated October 5, 2026 ).

Key Observations and Takeaways

Current analytical results targeting both down-dip (RIFT26-025 and RIFT26-026) and northwest (RIFT26-027 and RIFT26-028) extensions of the Trinity Zone confirm that the high-grade, west-plunging mineralized body extends an additional ~90 m west and 100 m northwest of previously reported RIFT26-024, which returned 3.55% REO over 116.0 m (see news release dated October 5, 2026 ). Together with previously reported drilling, Trinity Zone mineralization has now been traced over approximately 600 m of north-south strike and ~500 m of western down-dip extension within the 700 m target corridor, and it remains open in all directions. All four drillholes returned broad intervals of >2.00% REO, demonstrating that the thickness and grade of the zone are maintained as it plunges west and extends northwest.

Western Down-dip Extension

RIFT26-026 returned a continuous interval of 2.52% REO over 223.3 m from 423.2 m downhole [approximately 390 m vertical depth from surface], the broadest interval above 2.50% REO reported at Rift to date. The interval, when compared to previously reported results within drillhole fence A-A', suggests a potential thickening of the mineralized zone to the west. The interval contains multiple higher-grade zones including 3.43% REO over 26.3 m from 423.2 m, 3.06% REO over 20.9 m from 493.1 m, 3.54% REO over 38.7 m from 526.8 m and 3.01% REO over 22.2 m from 593.5 m which suggests the emerging high-grade core of >3.00% REO mineralization identified from previously reported RIFT26-024 (3.55% REO over 116.0 m, see news release dated October 5, 2026 ) continues to the west (Figure 2 below).

RIFT26-025 returned 2.49% REO over 123.3 m from 384.0 m downhole, including 3.45% REO over 37.1 m from 457.0 m, which contains two discrete higher-grade intervals of 4.00% REO over 8.1 m from 459.4 m and 4.03% REO over 6.6 m from 487.5 m. Located approximately 85 m west of previously reported RIFT26-019 (2.12% REO over 197.5 m) on drillhole fence B-B′ (see news release dated September 8, 2026 ), this interval confirms that the high-grade Trinity Zone continues down-dip to the west along this fence (Figure 3 below).

Northwest Extension

RIFT26-027, located approximately 100 m north of drillhole fence A-A′, intersected two discrete mineralized horizons. A shallow, high-grade interval of 4.43% REO over 5.9 m from 179.4 m downhole, and a deeper zone of 3.18% REO over 47.0 m from 373.6 m within a broader envelope of 2.07% REO over 85.1 m. Although narrower than the intervals to the south, the returned grades of >3.00% REO demonstrate that high-grade Trinity Zone mineralization continues north of the A-A' fence.

RIFT26-028 , the northwesternmost hole drilled to date at Rift, is located approximately 100 m north of fence A-A′ and 100 m west of RIFT26-027. It returned 2.03% REO over 62.1 m from 505.9 m downhole, including 3.13% REO over 16.6 m from 527.6 m and 4.30% REO over 7.4 m from 533.8 m, within a broader mineralized envelope of 1.64% REO over 125.0 m from 443.0 m. Trinity Zone mineralization remains open down-dip to the west and along strike to the north of RIFT26-028.

To date, twenty-eight (28) of the forty (40) completed drillholes have analytical results released. Results contained herein continue to highlight significant intervals of >3.00% REO within a broader >2.00% REO mineralized envelope, together with the positive rock attributes observed to the west demonstrate strong potential for further Trinity Zone expansion (see Figures 1-3 above). Additionally, these intercepts have now traced Trinity Zone mineralization approximately 600 m of N-S strike and approximately 500 m of western down-dip extension within the greater 700 m target corridor.

Program Status and Next Steps

The Company continues to drill with a single rig with drilling planned until year-end. Additional assay results will be released as received, vetted and interpreted. The Company remains on track to deliver an inaugural mineral resource estimate at the Rift Project before the end of Q1/2027.

Quality Assurance / Quality Control

All drilling was completed with a track-mounted diamond drill rig with HQ-size core and all drill core samples have been or will be shipped to Activation Laboratories Ltd. (Actlabs) preparation facility in Ancaster, Ontario, for standard sample preparation (code RX1) which includes drying, crush ( ₂ and Ta _₂ O _₅ (0.003%), Code 8 - REE Assay (lithium metaborate/tetraborate fusion with subsequent analysis by ICP and ICP/MS). Drill core was saw-cut with half-core sent for geochemical analysis and half-core remaining in the box onsite.

A Quality Assurance/Quality Control protocol was incorporated into the program and included the insertion of certified reference material and silica blanks at a rate of approximately 5% and 5%, respectively. Additional analysis of pulp-split and reject-split sample duplicates was also completed at a rate of approximately 5% and 2.5%, respectively, to assess analytical precision at different stages. Actlabs Canada is independent of the Company.

Management cautions that the interception of carbonatite and associated hematite alteration is not necessarily indicative of mineralization. Assay results are required to confirm the presence, grade, and significance of any mineralization.All intercepts reported in this news release represent core length (apparent width). True widths have not yet been determined.
