TEAKO EXPANDS CORE PORTFOLIO WITH TYNSET COPPER-ZINC-SILVER MASSIVE SULFIDE PROJECT

Teako Minerals Corp. has added the 100-per-cent-owned Tynset copper-zinc-silver (Cu-Zn-Ag) volcanogenic massive sulphide (VMS) project to the company's core project portfolio in central Norway, which also includes the Lokken-Venna VMS district. The Tynset project was acquired by the company through staking, and represents a high-priority and advanced-stage exploration target supported by a substantial amount of historical and recently published geological data that collectively indicate a favourable geological setting for Cu-Zn-Ag VMS deposits.

The company currently expects drill target definition work at the Tynset project to be completed in mid-2026, with the initial diamond drill testing of priority targets to be undertaken during H2 2026.

Highlights:

• The 100-per-cent-owned Tynset project was acquired by the company through staking and represents a high-priority and advanced-stage exploration target covering approximately 19 km of prospective stratigraphy in the bimodal Hersjo volcanic belt for the discovery of Cu-Zn-Ag VMS deposits.
• A significant database of both historical and recently published geological data exists and supports the concept of the Tynset project being a favourable geological setting for VMS-style Cu-Zn-Ag mineralization.
• The company has already digitized a significant amount of the available historical exploration data collected across the belt, including 1,400 soil and 23 rock chip samples, 335 stream sediment samples, and 1,800 ground magnetometer readings. These results have allowed for the definition of priority areas for immediate follow-up field review.
• Recently published airborne geophysical data from the Norwegian Geological Survey indicates areas of magnetic highs which are interpreted by the company to represent potential volcanic centres, with a priority 1 target, Storbekken, having already been identified.
• The Storbekken target also shows significant Cu-Zn soil anomalism over approximately five kilometres of strike length, coincident with hydrothermally altered and mineralized felsic volcanics.
• The next steps for the Tynset project will be drill target definition activities, including structural mapping, outcrop sampling, an induced polarization (IP) geophysical survey followed by initial diamond drilling on priority targets.

About the Tynset project

The Tynset project is 100 per cent owned by the company and is located in central Norway within the Tynset municipality, Innlandet County. The Tynset project consists of 10 granted exploration claims (covering a total area of 88 square kilometres) that covers approximately 19 km of prospective strike length of the bimodal Hersjo volcanic belt, which is considered to be fertile for the development of Cu-Zn-Ag VMS systems. The project benefits from established infrastructure, including a railway line running along the project's eastern boundary that connects to the deep-sea ports in the Trondheim area. The Norwegian National Road 3 also crosses the project area. The Tynset project is contiguous to the Sivilvangen project in which the company holds a 10-per-cent free-carried ownership interest up until final investment decision through its partnership with Nordic Minerals AS, a wholly owned subsidiary of United Minerals Australia Pty. Ltd. (see company press release dated Jan. 5, 2026).

The Tynset project is supported by a significant historical database that indicates a favourable geological setting for Cu-Zn-Ag VMS mineralization. The Tynset project was operated by Norwegian mining company Folldal Verk A/S in the 1980s and is understood by the company to have ceased its exploration efforts in the late 1980s due to declining commodity prices and changes in strategic objectives.

From a geological perspective, the Tynset belt consists of a bimodal volcanic sequence (both mafic and felsic volcanic rocks), together with intercalated metasedimentary rocks (including graphitic phyllites), and local sulphide occurrences. The company has digitized a significant amount of historical exploration data1 collected across the belt including i) over 1,400 soil samples (with results returning up to 470 parts per million Cu (copper) and 765 ppm Zn (zinc)) (Folldal Verk A/S, 1981, 1982) ii) 335 stream sediment samples (returning up to 335 ppm Cu, 1,323 ppm Zn and 47 ppm Pb) (Krog, 1968), iii) over 1,800 ground magnetometer measurements (Cuttle, 1982) and iv) 23 rock chip samples reaching up to 2.44 per cent Cu, 30.93 per cent Zn and 14.94 per cent Pb (Folldal Verk A/S, 1982), with NGU samples also showing grades of up to 197.1 g/t Ag (NGU, 2015).

These data are supported by recently published airborne geophysical data from the Norwegian Geological Survey (NGU), from which a highly prospective priority 1 target, Storbekken, has been identified. The Storbekken target shows significant Cu-Zn soil anomalism over approximately five km of strike length, coincident with hydrothermally altered and mineralized felsic volcanics. Logging data from limited historical drilling (five holes totalling 585 m) indicate that intense hydrothermal alteration was intersected (which has been interpreted by the company to be indicative of proximity to a hydrothermal system associated with VMS mineralization). Limited assays from historical drilling (only 30.25 m of core were analyzed, and solely for Cu and Zn) returned low-grade intervals of Cu and Zn, although no assays are available for Ag. The best visual interval recorded from 45.60 to 47.40 m in diamond drill hole S-83-4 was estimated to contain 10 to 15 per cent sphalerite, however it was not assayed (Bjerkgard, 1990).

With prospective geology, extensive soil anomalism, and surficial indications of both hydrothermal alteration and mineralization, Teako believes that this target has significant potential to host a new Cu-Zn-Ag VMS discovery. Outside this Storbekken priority 1 target, the company has identified further prospective target areas within the Tynset project where strong aeromagnetic anomalies are interpreted by the company to represent potential volcanic centres that may host VMS mineralization.

Next steps

The next steps for the Tynset project include field-based exploration activities -- including structural mapping, outcrop sampling and an induced polarization (IP) geophysical survey -- with follow-up diamond drilling on priority targets currently expected to be undertaken during H2 2026.

Update on other core projects

The next steps for the Venna project include further geological mapping and systematic sampling, currently anticipated to be carried out during H2 2026. These activities will build on the positive results of the 2025 field program (see company press release dated Dec. 8, 2025) and are designed to refine and prioritize target areas for subsequent advanced geophysical surveys.

The company is currently conducting a comprehensive review and evaluation of all available data, together with available options, in respect of its Lokken project.

About Teako Minerals Corp.

Teako Minerals is a Vancouver-based mineral exploration company committed to acquiring, exploring and developing mineral properties in Norway, focusing on critical metals such as copper and zinc in massive sulphides. By leveraging leading-edge exploration technologies and strategic partnerships, Teako aims to address the growing demand for essential minerals while generating value for shareholders and stakeholders alike.

Teako, within its Norwegian project hub owns 62 projects 100 per cent and holds a 10-per-cent economic interest in the four rare-earth elements (REE) projects owned by Fritzoe Skoger AS and a 10-per-cent non-dilutive free carried ownership interest in a five copper, gold and silver projects owned by Nordic Minerals AS, a wholly owned subsidiary of United Minerals Australia Pty. Ltd., as further described on the company's website.

Teako's project hub, including the Lokken, Venna and Tynset main projects, covers an extensive land package prospective for copper, cobalt, zinc, gold, silver, platinum group elements (or PGE), uranium, antimony, molybdenum, tungsten and rare-earth-elements. The project hub strategy was initially developed from the company's first-mover advantage in-country, leveraging both technical skill and strong local community engagement to acquire and advance groups of both core and non-core assets. Core assets such as the Lokken, Venna and Tynset projects remain integral to the company's self-financed exploration programs, whereas the company aims to retain exposure to exploration success on non-core assets through securing deals with strong partners. These deals, if secured, are intended to potentially bring in capital and/or continuing cash flow, retain upside exposure and reduce overall risk, thereby strengthening Teako's foundation.
