Tamarack, Minnesota--(Newsfile Corp. - April 9, 2026) - Talon Metals Corp. (TSX: TLO) (OTCID: TLOFF) (" Talon " or the " Company ") is pleased to report new step-out drilling results from the Vault Zone at the Tamarack Nickel-Copper-Cobalt Project in Minnesota.

The latest results further support the interpretation of the Vault Zone as a stacked mineralized system, including confirmation of a fourth mineralized level within the broader stacked Vault Zone. Additional drilling has also supported continuity of mineralization at other levels, while follow-up borehole electromagnetic (" BHEM ") surveying has identified an additional untested off-hole anomaly, highlighting potential for further expansion beyond the current drill intercepts. Highlights Drill hole 25TK0566 intercepted 7.73 meters of Massive Sulphide Unit (" MSU ") and Mixed Massive Sulphides (" MMS ") grading 5.56% Ni, 7.40% Cu, 0.05% Co, 6.05 g/t Pt+Pd, and 6.35 g/t Au (12.44% NiEq or 23.30% CuEq) starting at 721.57 meters.

New drill hole 25TK0568 intercepted 10.35 meters of MSU, MMS, and disseminated sulphides starting at 611.57 meters, confirming a fourth mineralized level within the broader Vault Zone system. New drill hole 25TK0568A intercepted 8.88 meters of MSU starting at 733.16 meters, supporting continuity of mineralization at depth within the broader Vault Zone system. Follow-up BHEM surveying on the hole also identified an additional untested off-hole anomaly, suggesting potential continuation of the system to the east and south.

Talon plans to continue drilling to test this target and further delineate the Vault Zone. New drill hole 25TK0569A intercepted two mineralized intervals in the Vault Zone, supporting continued follow-up drilling in the area. "The Talon in-house drilling team continues to map out new Vault Zone mineralization through our integrated geophysics and drilling program," said Brian Goldner, Talon's Chief Exploration Officer.

"The intercept in drill hole 25TK0568 confirms a fourth level of mineralization at 611.57 meters, which is higher up in the system than the deeper intercept in drill hole 25TK0568A. Drill hole 25TK0568A also intercepted 8.88 meters of MSU and identified an additional off-hole anomaly to the southeast. Talon will target this new off-hole BHEM anomaly next and continue to follow the mineralization with borehole electromagnetic surveys guiding the way." Drill Hole 25TK0566 Assays Drill hole 25TK0566 is an approximate 12-meter step out to the south from discovery hole 16TK0250, which previously intercepted 8.25 meters (from 707.77 to 716.02 meters) grading 12.62% Ni, 13.88% Cu, 0.12% Co, and 11.78 g/t Pt+Pd and 6.17 g/t Au (see the Company's May 1, 2025, press release ).

Drill hole 25TK0566 intercepted 7.73 meters of MMS/MSU grading 5.56% Ni, 7.40% Cu, 0.05% Co, 6.05 g/t Pt+Pd, and 6.35 g/t Au (12.44% NiEq or 23.30% CuEq) starting at 721.57 meters.

New Mineralized Level of Massive Sulphide in the Vault Zone: Drill Hole 25TK0568 New drill hole 25TK0568 intercepted 10.35 meters of MSU/MMS interlayered with disseminated sulphide starting at 611.57 meters (assays pending; see Figures 1 and 2).

This newly identified mineralized zone occurs at approximately the 610-meter level, about 100 meters above discovery hole 16TK0250, which identified MSU accumulation on the 710-meter level. Together, these results support the interpretation of the Vault Zone as a stacked mineralized system and confirm a fourth mineralized level within the broader Vault Zone.

(Assays are pending). (See Figures 3, 4, and 5) This intercept ties into previously reported mineralization in drill holes 16TK0250 and 25TK0566, supporting continuity of mineralization at depth within the broader Vault Zone system.

Follow-up BHEM surveying on drill hole 25TK0568A identified an additional untested off-hole anomaly, suggesting potential continuation of the system to the east and south.

The hole, drilled approximately 12 meters north of previously reported drill hole 25TK0563, intercepted two mineralized intervals in the Vault Zone. At 694.03 meters, the hole intercepted 5.49 meters of MSU/MMS, and starting at 766.26 meters, 10.3 meters of MSU/MMS intercalated with disseminated sulphide mineralization (See Figures 6 and 7; assays pending). These results support continued follow-up drilling in this part of the Vault Zone.

About the Vault Zone As outlined in the Company's June 5, 2025 press release, the Vault Zone discovery drill hole 25TK0563 intercepted a combined 34.9 meters of massive sulphide mineralization grading 14.86% Ni, 15.37% Cu, 0.11% Co, 24.96 g/t Pt+Pd and 9.18 g/t Au (28.88% NiEq and 57.76% CuEq) starting at 762.34 meters, demonstrating a new mineralized system beyond the existing resource footprint. Since discovery, Talon has been stepping out around the system using BHEM to generate targets and precision drilling to test continuity and extensions.

Recent step-out drilling continues to intercept massive and mixed massive sulphides, indicating that the system remains open and expandable. Three of Talon's in-house drill rigs are actively drilling the Vault Zone to continue expanding mineralization. Update on Tamarack Feasibility Study As part of the ongoing feasibility study for the Tamarack Nickel-Copper-Cobalt Project, Talon is also evaluating the potential to process Tamarack ore at the Humboldt Mill as an alternative development pathway.

Feasibility work for the Beulah Minerals Processing Facility will continue as planned while the Company assesses this additional option. This evaluation is expected to defer the final project configuration decision and publication of the feasibility study to the second half of 2026, while the environmental review and permitting process is expected to continue on its current schedule. QUALITY ASSURANCE, QUALITY CONTROL, AND QUALIFIED PERSONS The Talon sample preparation, security, and Quality Assurance (" QA ") / Quality Control (" QC ") protocols for the Tamarack Nickel-Copper Project are consistent with industry best practices and Canadian Institute of Mining, Metallurgy and Petroleum Mineral Exploration Best Practice Guidelines (November 2018).

Talon has implemented documented QA programs that incorporate written procedures, acceptable industry software, database organization, and standardized data presentation, all of which contribute to confidence in the integrity of the dataset. The QC protocol has been documented (see also the November 2022 Technical Report) and consistently applied since Talon's involvement with the Tamarack Nickel-Copper Project. The QA/QC program is based on the systematic insertion of certified reference materials (" CRM "), including a variety of standards, blanks (materials containing no economic minerals), and duplicate samples, which are used to monitor contamination, precision, and analytical accuracy at the primary assay laboratory and to prevent inaccurate data from being accepted into the assay database.

Samples are submitted in batches of approximately 250 samples. Within each batch, QA/QC materials are inserted at a rate of approximately one QA/QC sample for every ten core samples, including CRM standards inserted at the front end of massive sulphide mineralization, blanks inserted immediately following massive sulphide mineralization, and duplicate samples inserted approximately every 10 samples. Sample security and chain-of-custody procedures are maintained throughout the sampling and analytical process.

Core samples are prepared and stored in a secure facility prior to shipment. Samples are placed into plastic bins or sealed totes, which are secured using tamper-evident security tags. Before sealing, a chain-of-custody form is placed inside each container.

The containers are transported from the core facility to the ALS laboratory in Thunder Bay, Ontario for preparation, and are subsequently shipped to ALS Laboratories in Vancouver, British Columbia for analysis, where the chain-of-custody documentation is signed by laboratory personnel and returned to Talon upon receipt, confirming sample integrity.
