Vancouver, British Columbia--(Newsfile Corp. - 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
Teako commences field program at the high-grade Tynset copper-zinc-silver ("Cu-Zn-Ag") volcanogenic massive sulphide ("VMS") project in central Norway. The current work program is designed to refine drill targets for testing on a priority basis in Q4 2026-Q1 2027.
Tynset Project has been expanded 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.
Geovisor Oy has been engaged to complete approximately 10 line kilometres of IP surveying across the Storbekken Priority 1 target area (see Figure 1) commencing mid October 2026.
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.

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
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.
