VANCOUVER, B.C. | August 18, 2026 | Teako Minerals Corp. (CSE: TMIN) (the “Company” or “Teako”) is pleased to announce the commencement of its 2026 field program at the Tynset copper-zinc-silver (“Cu-Zn-Ag”) volcanogenic massive sulphide (“VMS”) project in central Norway. The current field program will include additional geological mapping and sampling, together with an Induced Polarization (“IP”) geophysical survey, designed to build upon the Company’s existing datasets and produce refined and high-priority drill targets within the Storbekken Priority 1 target area. The Company currently expects first diamond drill testing of priority targets at Tynset in Q4 2026-Q1 2027.

The Company also announces that it has expanded the Tynset Project through the staking and granting of four additional exploration licences covering the high-priority Nonsvola and Vingelen target areas (see Figure 1) thus expanding the strike length of the prospective volcanic belt.

Highlights

About Field Program and Induced Polarization Survey

The 2026 field program at the Tynset Project will consist of i) detailed geological and structural mapping, together with systematic outcrop sampling for geochemical and spectral laboratory analysis (the “Field Program”), and ii) an IP geophysical survey covering the most prospective stratigraphy for high-grade VMS-style mineralization. The Field Program is designed to refine the positions of key lithological contacts and better characterize known mineralized and altered outcrops through geochemistry and spectral data. The collection of structural data along the planned IP survey lines will also improve the interpretation of the geophysical results. The Company will prioritize the resistivity and chargeability features which can be tied to the most promising surface geology, to improve the probability of successfully drilling a copper-rich VMS system.

Geological and structural mapping will be completed along the IP survey lines (see Figure 1), around known mineral occurrences and across areas of historical soil anomalism. Structural measurements will be collected using a consistent methodology to support the development of an improved three-dimensional geological interpretation and assist with the interpretation of geophysical data, historical drilling and future drill results.

Sampling will include mineralized material, representative whole-rock characterization samples and samples selected for spectral analysis. The resulting geological, structural, geochemical and spectral datasets are intended to improve the Company’s understanding of alteration patterns, mineralized trends and subsurface geometry.

A critical outcome for the IP survey can be directly linked to the known geology at Storbekken, where thick packages of felsic volcanic rocks, interpreted to have been altered to quartz-sericite schists, contain variable quantities of disseminated pyrite. The IP survey is expected to help delineate the subsurface geometry and electrical response of these zones, with elevated resistivity potentially associated with the high quartz content and chargeability responses potentially reflecting disseminated sulphides. Comparing surface geological, geochemical and alteration data on these zones with the IP profiles will assist with identifying areas where favourable geophysical responses coincide with the most intense and prospective alteration, helping to vector towards a potential prospective core of the hydrothermal system and guide drill targeting. Contact zones between felsic volcanic rocks and graphitic schists could be highly prospective target horizons, marking a sea-floor interface on which exhalative VMS mineralization may have originally formed. An example is seen at the Stekenjokk deposit in Sweden, a key analogue for the Tynset project. Priority drill targets will be defined where promising IP responses correlate with prospective surface geology, combining geophysical, geological and geochemical datasets to ensure that drilling tests the most promising areas of the Storbekken target.

Details of the IP Survey

The Company has engaged Geovisor Oy to complete approximately 10 line kilometers of IP surveying across the Storbekken Priority 1 target area (see Figure 1) scheduled for mid October 2026. The resulting IP dataset is expected to provide the principal three-dimensional geophysical framework for refined drill targeting to an anticipated depth of 200-350 metres, with priority anomalies identified and interpreted from each surveyed profile.

Surface geological observations and laboratory results from the Field Program will be incorporated into the IP sections, allowing the inverted geophysical responses to be compared directly with mapped lithological contacts, alteration, mineralization and structural features. This integrated interpretation is intended to improve the geological context of identified IP anomalies and support the refinement of high-priority drill targets.

About the Tynset Project

The Tynset Project is 100%-owned by the Company and is located in central Norway within the Tynset municipality, Innlandet County (see Figure 1). The Tynset Project consists of 14 granted exploration claims (covering a total area of 121 km2) that includes approximately 29 km of prospective strike length of the bimodal Hersjø Volcanic belt, which is considered to be fertile for the discovery of Cu-Zn-Ag VMS systems (Grenne, Vokes and Ihlen, 1999). 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% 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 January 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 1980’s due to declining commodity prices and changes in strategic objectives.

Figure 1: Overview of the Tynset Project including planned IP lines

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 sulfide occurrences. The Company has digitized a significant amount of historical exploration data1,2 collected across the belt including i) over 1,400 soil samples (with results returning up to 470 ppm Cu and 765 ppm Zn) (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% Cu, 30.93% Zn and 14.94% 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 the highly prospective priority 1 target, Storbekken, has been identified. The Storbekken target shows significant Cu-Zn soil anomalism over ~5 km of strike length, coincident with hydrothermally altered and mineralized felsic volcanics. Logging data from limited historical drilling (5 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 30.25m 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 10-15% sphalerite, however no assay results are available for the interval (Bjerkgård, 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. The Nonsvola target, found toward the north-east end of the project area, shows clear similarities to the Storbekken target. Base metal mineralization is recorded both in outcrop (NGU rock chip grades up to 2.60 % Cu, 4.26 % Zn and 0.49 g/t Au (NGU, 2015))2 and in historic drill core, in a sequence of altered felsic volcanics and mixed volcaniclastics that been altered to quartz-sericite and quartz-chlorite schists. Targeting is supported by strong soil anomalies (up to 1,700 ppm Zn, 200 ppm Cu and 26 ppm Pb)(Bakke and Wilberg, 1984)2, contributing to a highly prospective target ready for follow-up investigations.

Adding to the potential of the north-east end of the project area is the historic Vingelen Mine, which sits ~4.5 km north-east and along strike of the Nonsvola target. The NGU report that the mine produced an estimated 30 Kt of sulphide ore at a grade of 1.30 % Cu, with historical drilling indicating mineralization down to a depth below surface of ~210 m (NGU, 2024)3. Two subparallel ‘plates’ of sulphide mineralization were historically found at the deposit, separated by 10 m of host rock. The north plate was the thicker of the two (up to 4 m) and was the focus of historic production. In 1983 Folldal Verk AS attempted to drill through both plates at depth with a single hole, intersecting the upper plate (1.70 m at 0.81 % Cu & 2.35 % Zn from 208.80 m) but was stopped short of the lower plate as the hole was abandoned due to unusually challenging winter drilling conditions (i.e. -30 °C) (Bakke and Wilberg, 1984). The deposit is interpreted as a fold repetition of the same sulphide horizon across a tight isoclinal fold (Bjerkgård, 1989), making the potential hinge zone a priority target for the discovery of a thickened and potentially economic sulphide body. The project also covers multiple untested greenfields areas where strong aeromagnetic anomalies are interpreted by the Company to represent potential volcanic centres that may host VMS mineralization.

1,2 Teako has not performed sufficient work to verify the published data reported above, but the Company believes this information to be considered reliable and relevant. Results reported are maximum values and may not be representative of all samples collected within the area being evaluated

(CSE: TMIN) (FSE: O8U) (OTCPK: TMINF) (the “Company” or “Teako”) is pleased to announce that it has entered into a non-binding Letter of Intent (“LOI”) with MERIDIANA Capital Group GmbH (“MERIDIANA”) dated July 8, 2026, outlining the framework for a recapitalization transaction resulting in the creation of a German-listed silver-focussed exploration company through the combination of certain of Teako’s Norwegian silver projects and a portfolio of German-sponsored exploration projects.

Pursuant to the proposed transaction structure, Teako shall contribute a 90% interest in seven (7) strategic Norwegian silver projects to a newly formed Norwegian subsidiary to be established by Teako (“NewCo”). All of the issued and outstanding shares of NewCo will subsequently be contributed for consideration equal to EUR 3,600,000 to a German listed company identified by MERIDIANA, which is ultimately expected to be renamed, and referred to herein as the “Resulting Issuer”. The consideration payable to Teako shall consist of EUR 100,000 in cash and EUR 3,500,000 in common equity of the Resulting Issuer. Concurrently with Teako’s contribution of the NewCo shares to the Resulting Issuer, MERIDIANA or an affiliate will contribute all of the issued and outstanding shares of a separate Norwegian exploration company holding a portfolio of twelve silver-exploration projects to the Resulting Issuer in exchange for common equity of the Resulting Issuer.

The proposed transaction is intended to establish a dedicated silver exploration platform combining Teako’s Norwegian silver portfolio with MERIDIANA’s additional twelve projects under a German public company structure. The parties believe that the transaction has the potential to enhance access to capital markets to accelerate exploration on the contributed projects, while creating a focussed silver exploration vehicle with a substantial Norwegian asset base. Teako will retain exposure to future project development through its retained 10% interest in the Projects and ownership interest in the Resulting Issuer. Teako is also expected to become the preferred provider of Norwegian exploration services (on standard commercial terms) to the Resulting Issuer going forward.

Highlights

• Creation of a German Listed Pure-Play Silver Explorer: Teako has agreed to contribute a 90% interest in seven (7) strategic Norwegian silver projects: Kvittinden, Husvika, Sund, Leland, Greipfjellet, Hyllvatnet and Vinterskard (the "Projects"), and MERIDIANA has agreed to contribute a further 12 silver projects, to an existing publicly listed entity which, upon completion of the proposed transactions, will be the Resulting Issuer. The Resulting Issuer will be a Germany-listed silver-focused Norwegian exploration company.

• Retained Strategic Upside: The transaction will allow Teako to further crystallize value from its Norwegian portfolio while maintaining significant exposure to future discoveries through both an equity ownership in the Resulting Issuer and retained direct interests in the 7 silver projects.

• Equity Position: Teako will be issued such number of fully paid common shares in the capital of the Resulting Issuer having an aggregate value of €3,500,000 (approximately C$5,660,000) upon closing of the transaction, which is expected to represent approximately 38.4% of the outstanding shares of the Resulting Issuer at closing.

• Cash Payment: Teako shall also receive a cash payment of €100,000 (approx. C$160,000) payable upon closing.

• 10% Free Carried Interest: Teako will retain a 10% beneficial ownership interest in each of the Projects, carried until the point of a Final Investment Decision (“FID”) on the Projects.

• Work Commitments: To ensure advancement of the Projects, the Parties have agreed to cause the Resulting Issuer to use its best efforts to conduct minimum aggregate expenditures of €2,250,000 (approximately C$3,650,000) within 3 years of the closing. These commitments are to be incurred in aggregate across the Projects as outlined in further detail below.

Terms of the LOI

Pursuant to the LOI, Teako and MERIDIANA have agreed to use their commercially reasonable efforts to enter into a definitive contribution agreement (the “Agreement”) within 90 days. Completion of the proposed transaction and the successful listing of the Resulting Issuer shares issuable to Teako remain subject to a number of conditions, including formation of NewCo, preparation of valuation and business plan materials, and certain regulatory and exchange approvals in Germany.

Teako will retain a 10% free carried ownership interest (the “Free Carry”) until FID in each of the Projects. If at any time the Resulting Issuer makes a FID to commence commercial production on the Projects or a Project, Teako and the Resulting Issuer shall form a joint venture (the ”JV”) pursuant to a definitive joint venture agreement (the “Joint Venture Agreement”). Upon FID, the Resulting Issuer will be responsible for sourcing funding to bring the Projects or the Project into production, and Teako shall not be responsible for any costs of establishing the JV or financing the Projects until commercial production has commenced.

The LOI also provides Teako with certain anti-dilution protections so that any financing of the JV will not impact Teako’s Free Carry prior to the point of commercial production. After the commencement of commercial production, all Joint Venture interest holders will participate in the costs and distributions of the Joint Venture pro rata. Dividends or distributions will start to be distributed to the parties after any financing loans made to the JV are paid off from the revenues from the production. Teako shall have no parent obligations for repayment in the event the mine is closed prior to final repayment of any such loan(s).

The Agreement shall contain a commitment by the Resulting Issuer to use its best efforts to incur work commitments of not less than €2,250,000 (approximately C$3,650,000) on the Projects following closing on the following schedule:

Timeline (post closing) Minimum exploration expenditure
By 1st anniversary €500,000
By 2nd anniversary €750,000
By 3rd anniversary €1,000,000
Total commitment €2,250,000

The Resulting Issuer will establish its own dedicated team of personnel. In addition, Teako may be engaged on an as- needed basis to provide exploration services in Norway and other services to the Resulting Issuer on customary commercial, arm’s-length terms at market rates.

About the Projects The seven Projects (see Figure 1) that will be contributed by Teako under the LOI are all 100% owned by Teako and are all located within highly prospective belts for the discovery of high-grade polymetallic and silver deposits in Central and Northern Norway.

Figure 1: Location of the Projects
Figure 1: Location of the Projects

Husvika Project

Located in the Nordland region of Northern Norway, the Husvika Project consists of seven (7) licence claims (covering a total area of 48,5 km2), and benefits from exceptional infrastructure, including the Husvika port. Historic mining and modern exploration data, including rock chip sampling undertaken by the Norwegian Geological Survey (”NGU”), indicate the potential for high-grade polymetallic skarn-type mineralization with strong silver enrichment and district-scale exploration potential (see Figure 2).

Figure 2: Overview of the Husvika Project
Figure 2: Overview of the Husvika Project

At the centre of the project lies the historic Husvika zinc-lead-silver (”Zn-Pb-Ag”) deposit, where previous mining campaigns between 1897 and 1951 reported extraction of an estimated 8,000 tonnes of ore from several high-grade lenses distributed along a 1.5 km mineralized trend (Torgersen, 1928). Mineralization occurs within broadly N-S-trending skarn- hosted sulphide systems containing sphalerite, galena and silver and with a cumulative strike length exceeding 5 km (Birkeland & Bjørlykke, 1993). The broader Husvika district hosts numerous historic workings, including the Hilda Mine, Nordre Sivertsen, Søndre Sivertsen, Lille Hatten, and several satellite occurrences distributed along the mineralized corridor.

This widespread mineralization demonstrates possible continuity and scale of the system throughout the project area. Importantly, historical geophysical surveys identified conductive anomalies at depth beneath the southern part of the project area, suggesting the potential for mineralization extensions below historically mined levels (NGU Report BV4058, 1974). Historical exploration also identified multiple gold anomalies in stream sediment surveys proximal to the main Pb- Zn-Ag mineralization, highlighting the potential for additional precious metal enrichment within the district (BP Minerals, 1984).

Kvittinden & Greipfjellet Projects

Kvittinden Project

The Kvittinden Project is a polymetallic target opportunity located in Nordland County, Norway. The Project consists of 27 license claims (covering 220 km2) and benefits from excellent regional infrastructure, including established forestry and access roads, proximity to a local airport, and connectivity to a deep-water port and regional airport in Mosjøen. Kvittinden sits within highly prospective metasedimentary and metavolcanic rocks, which host multiple styles of mineralization, including volcanogenic massive sulphide (”VMS”), Mississippi Valley-Type (”MVT”), and skarn mineralization.

Historical exploration by major Scandinavian mining groups including Boliden and LKAB identified high-grade mineralized boulders across the property (see Figure 3) with maximum silver-lead grades of 423 g/t Ag and 30% Pb (Lilljequist, 2014). The NGU also sampled outcrops in the area which have presented grades to 132 g/t Ag and up to 10 % Zn, highlighting the polymetallic nature of this area. The mineralized boulder locations are consistent with ice flow directions and extend over approximately 10 km, suggesting the presence of a significant undiscovered bedrock source (Acosta-Gongora et al., 2024) with mineralized horizons at Tverrelva (up to 9.3 % Zn) being strong source candidates.

More recent work by Scandinavian Resources advanced the understanding of the region through airborne electromagnetic (“VTEM”) and magnetic surveys alongside diamond drilling campaigns (Forslund, 2011, Hannans, 2012). Teako has since acquired and reprocessed the VTEM dataset using modern Maxwell plate modelling, significantly refining the project’s drill targeting capability with identification and assessment of 49 conductive Maxwell plates. Of these, 15 occur within prospective greenstones along the Tverrelva trend and are considered high-priority VMS targets. With strong infrastructure, compelling historical exploration results, modern geophysical targeting, and district-scale polymetallic potential, the Kvittinden Project represents a highly prospective exploration asset within Norway’s emerging critical minerals sector.

Greipfjellet Project

The Greipfjellet Project is also located in Nordland County, Norway. The Project consists of 10 license claims (covering 92 km2) and also benefits from excellent regional infrastructure, including local roads, airport access, and proximity to a deep- water port in Mosjøen (see Figure 3). Previous work includes a VTEM airborne geophysical survey completed by Scandinavian Resources AB in 2010 and regional till sampling conducted by the NGU. Teako has acquired and reprocessed the historical VTEM dataset to improve target definition and refine exploration priorities. Maxwell plate modelling by Geotech Airborne Ltd identified 49 conductive plates across the area many of which reside in the Greipfjellet licence area, several of which are located within prospective greenstone and felsic volcanic units considered favourable for VMS mineralization. These targets represent priority areas for future exploration and possible drill testing.

Geologically, the project area is composed primarily of rocks known to host base metal mineralization and similarities have been drawn with deposits such as Stekenjokk in Sweden and Bathurst in Canada. Geological and FDEM geophysical trends highlight indications that prospective geology may extend from the Swedish border hosting the Stekenjokk deposit into the Greipfjellet licences. Work undertaken by the NGU (Acosta 2024) has highlighted prospectivity across this region, with prospectivity for both precious and base metals noted across the licence area.

Figure 3: Overview of the Kvittinden and Greipfjellet Projects
Figure 3: Overview of the Kvittinden and Greipfjellet Projects

Hyllvatnet Project

The Hyllvatnet Project comprises a single licence claim (covering 10km2) and is situated north of Trondheimsfjorden, about 40 km north of the city of Trondheim. The project hosts three historical mineral occurrences along the contact between Paleoproterozoic migmatitic gneiss and younger metasedimentary rocks and greenstones of the Seve Nappe, partly characterised by elevated precious- and base-metal grades. The area benefits from excellent infrastructure, including direct road access via public and local forestry roads/hiking trails, as well as proximity to shipping facilities in Trondheim and the international airport at Stjørdal. Assay results from the NGU database exist for 14 samples collected across the mineral occurrence sites with grades averaging 133 g/t Ag and 1.94 % Cu and values reaching 248.6 g/t Ag, 6.2 % Cu and 0.67% Mo (Geo.ngu.no, 2026) (see Figure 4). The NGU have also reported geophysical (Induced Polarization) anomalies along the lithological contact (Figure 4). This, coupled with the notable surface grade data, highlights the prospectivity of the Project.

Figure 4: Overview of the Hyllvatnet Project
Figure 4: Overview of the Hyllvatnet Project

Sund and Leland Projects

Sund Project

The Sund Project consists of two license claims (covering 15 km2) and is located in Nordland, Norway, about 15 km east of Sandnessjøen and hosts the historic Ladingen trench (1930s), known for its silver and base-metal grades (see Figure 5). The area’s geology comprises marble interlayered with mica schist and gneiss, with proximal Caledonian granite intrusions. A 5 m long adit exposes a ~10 cm quartz vein with galena, arsenopyrite, and minor pyrite. The vein reportedly extends several metres along strike before disappearing beneath overburden on the shoreline. NGU sample assays (Geo.ngu.no, 2026) show elevated lead and silver in samples from the vein, with up to 2.13 % lead and 489 g/t silver.

Leland Project

Teako’s Leland Project is located in Nordland County and consists of 2 license claims covering 8.7 km2. The Project lies 17 km northeast of Sandnessjøen covering the historic Leirfjord lead–zinc–silver occurrences. Mineralization occurs as massive galena–sphalerite (± pyrrhotite) bodies hosted within calcitic marble of a Cambro–Silurian metasedimentary sequence situated adjacent to the Caledonian Lifjell granodiorite. The mineralization is structurally controlled, remobilized into fold hinges and marble–schist contacts. At the historical main Smøråsen pit, mineralization occurs in three lenses and a 1 m thick zone has been identified at Småhaugene.

Historical work includes mining in the 1880s – 1930s and an NGU exploration program in 1974 involving mapping, soil sampling, and VLF geophysics (Cramer, 1974). Rock chip samples over the areas from the NGU have returned assay grades up to 264 g/t silver, 10% zinc and 16% lead (NGU, 2015) (see Figure 5). Lead isotope data collected for a series of deposits throughout the region by the University of Oslo have linked the Leirfjord mineralization with other deposits in the region and studies have confirmed skarn-style mineralization (Birkeland 1993). Leirfjord has been classified as a “Husvika Type” and sits within a cluster of deposits including Husvika, Leirfjord, Langkilen and Svenningdale. Lead isotopes for these deposits overlap with the regionally significant Bindal batholith and the Caledonian of the Scandinavian massive sulphide deposits.

Vinterskard Project

The Vinterskard Project is a polymetallic exploration project measuring 10 km2 in size, with notable precious metal grades located in the Grane municipality of Nordland, representing an exciting opportunity to fully investigate this precious metal potential. Situated approximately 18 km from Trofors, the site benefits from excellent infrastructure, lying in close proximity to the E6 highway and local railway line, and is a mere 1.2 km from the nearest road. The regional geology is characterized by quartz-diorite units within the Helgeland Nappe Complex and the project is highlighted by the Skjerphaugen occurrence, a hydrothermal vein system reported to be approximately 0.7 m in thickness. Waste rock material contains disseminated galena and bands of nearly massive arsenopyrite locally reaching 3 to 4 centimeters in thickness. Historical NGU sampling has yielded significant high-grade results, with assays returning up to 29.08 g/t Au, 193.2 g/t Ag, and 2.97% Pb (29,733 ppm) (Geo.ngu.no, 2026) (see Figure 6). Furthermore, the quartz vein material returned up to 0.12% Co, presenting an additional target, yet to be fully assessed. Vinterskard currently remains largely untested by modern exploration, although with compelling historical high-grade gold, silver, and polymetallic results.

VANCOUVER, B.C. | April 21, 2026 | Teako Minerals Corp. (CSE: TMIN) (the “Company” or “Teako”) is pleased to announce the addition of the 100%-owned Tynset copper-zinc-silver (”Cu-Zn-Ag”) volcanogenic massive sulfide (”VMS”) Project to the Company’s core project portfolio in central Norway, which also includes the Løkken-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

About the Tynset Project:

The Tynset Project is 100%-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 km2) that covers approximately 19 km of prospective strike length of the bimodal Hersjø Volcanic belt, which is considered to be fertile for the development of Cu-Zn-Ag VMS systems (see Figure 1). 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% 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 January 5, 2026).

Figure 1: Overview of the Tynset Project
Figure 1: Overview of the Tynset Project

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 1980’s 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 sulfide 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 ppm Cu and 765 ppm Zn) (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% Cu, 30.93% Zn and 14.94% 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 (Figure 1). The Storbekken target shows significant Cu-Zn soil anomalism over ~5 km of strike length, coincident with hydrothermally altered and mineralized felsic volcanics. Logging data from limited historical drilling (5 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 30.25m 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 10-15% sphalerite, however it was not assayed (Bjerkgård, 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 December 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 Løkken Project.
