# Talon Metals Extends High-Grade Vault Zone with Step-Out Drilling in Multiple Sulphide Stacks *2025-12-11T07:30:00-05:00* Talon Metals Extends High-Grade Vault Zone with Step-Out Drilling in Multiple Sulphide Stacks New Drill Holes Confirm Lateral Extension of Massive Sulphide Mineralization Predicted by Borehole Electromagnetic Surveys Tamarack, Minnesota--(Newsfile Corp. - December 11, 2025) - Talon Metals Corp. (TSX: TLO) (OTCID: TLOFF) (**"Talon" **or the**"Company"**) is pleased to report **multiple successful step-out drill holes from the previously reported exceptional discovery intercepts**in the Vault Zone of the Tamarack Nickel-Copper-Cobalt Project in Minnesota (the "**Tamarack Nickel-Copper Project**"), as well as new assay results confirming **significant copper enrichment.** [](https://images.newsfilecorp.com/files/2443/277690_674435ff64e13931_001full.jpg) **Figure 1: The third (lower) Mixed Massive Sulphide (MMS) and Massive Sulphide Unit (MSU) mineralization intercepted in step out drill hole 25TK0563B** To view an enhanced version of this graphic, please visit: [https://images.newsfilecorp.com/files/2443/277690_674435ff64e13931_001full.jpg](https://images.newsfilecorp.com/files/2443/277690_674435ff64e13931_001full.jpg) **Highlights** - Drill hole 25TK0563B **intercepted 7.56 meters of Massive Sulphide **("**MSU**") in a 16-meter step out from drill hole 25TK0563 and is on the same stratigraphic horizon as the upper portion (20.4 meters) of the 34.9 meter discovery. - Drill hole 25TK0566 **intercepted 5.16 meters of MSU/MMS**in an approximate 16 meter step out to the south from discovery drill hole 16TK0250. Intercepts from 25TK0563B and 25TK0565 at the same stratigraphic horizon now provide 4 pierce points into the discovery. - Assays from drill hole 25TK0565 show significant grades considering sedimental dilution emphasizing the strength and persistence of copper enrichment across the Vault Zone. **Table 1: Assays for drill hole 25TK0565** | **Drill Hole ** **(#)** | **From (m)** | **To ** **(m)** | **Length (m)** | **Assay** | | **NiEq (%)** | **CuEq ** **(%)** | | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | **Ni (%)** | **Cu (%)** | **Co (%)** | **Pd (g/t)** | **Pt (g/t)** | **Au (g/t)** | **Ag (g/t)** | | | | | | | | **25TK0565** | 670.00 | 689.11 | 19.11 | 2.38 | 4.72 | 0.03 | 1.31 | 2.49 | 2.32 | 12.44 | 6.39 | 11.67 | | _including_ | 670.00 | 682.52 | 12.52 | 2.76 | 5.76 | 0.03 | 1.91 | 3.64 | 3.44 | 15.71 | 7.98 | 14.48 | | including | 685.12 | 689.11 | 3.99 | 2.67 | 4.36 | 0.05 | 0.28 | 0.47 | 0.25 | 9.12 | 5.35 | 9.88 | | and | 703.65 | 706.87 | 3.22 | 2.77 | 11.69 | 0.05 | 0.52 | 0.46 | 0.58 | 17.14 | 9.90 | 17.40 | **Please refer to Table 3 for further technical information** [](https://images.newsfilecorp.com/files/2443/277690_674435ff64e13931_002full.jpg) **Figure 2: Drill hole 25TK0565 mineralized interval from 670.00 meters to 689.11 meters.** To view an enhanced version of this graphic, please visit: [https://images.newsfilecorp.com/files/2443/277690_674435ff64e13931_002full.jpg](https://images.newsfilecorp.com/files/2443/277690_674435ff64e13931_002full.jpg) - Chalcopyrite veinlets intercepted at 880 meters in drill hole 25TK0566 provide new evidence to support the vertical plate from the borehole electromagnetic ("**BHEM**") survey in drill hole 16TK0248 and the potential for more stacked zones below the discovery in drill hole 25TK0563. **New Successful Step-out: Drill Hole 25TK0563B ** With three drill rigs fully operational and Talon's full exploration team at Tamarack, the Company is **rapidly expanding and delineating**the high-grade Vault Zone. As outlined in the Company's [November 4, 2025 press release](https://api.newsfilecorp.com/redirect/LqoBRhnzzp), BHEM results from drill hole 16TK0248, supported by high-conductivity plates modeled from drill holes 25TK0563 and 25TK0562, pointed to a laterally continuous massive sulphide horizon along the drill hole 25TK0563 stratigraphic level. The BHEM predicted lateral extension of the MSU, intersected in drill hole 25TK0563 is now confirmed by the new intercept in drill hole 25TK0563B. Drill hole 25TK0563B (see Figure 1) intercepted 7.56 meters (from 775.57 meters to 783.13 meters) of Mixed Massive Sulphide ("**MMS**") and MSU within the same stratigraphic horizon as the upper portion (from 762.34 to 782.73 meters) of the 34.9 meters of MSU previously intercepted in drill hole 25TK0563 located approximately 16 meters away (see Figure 3)**which averaged 28.88% NiEq and 57.76% CuEq**(see the Company's [June 5, 2025 p
