TEAKO COMPLETES FIELD PROGRAMS AT THE TYNSET COPPER-ZINC-SILVER PROJECT AND VENNA COPPER-COBALT-ZINC PROJECT, CENTRAL NORWAY

Teako Minerals Corp. has completed its 2026 field program at the Tynset copper-zinc-silver (Cu-Zn-Ag) volcanogenic massive sulphide (VMS) project. In addition to the Tynset program, the company also deployed a field crew to the Venna copper-cobalt-zinc (Cu-Co-Zn) VMS project (the Venna project) in order to complete additional fieldwork. Both the Tynset and Venna projects are 100 per cent owned by Teako, with the field programs undertaken forming part of the company's drill target generation initiatives on the two projects.

Follow-up work at the Tynset project is expected to include the previously announced ground geophysical survey (induced polarization, or IP) (see company news release dated Aug. 18, 2026) over the Storbekken priority 1 target, starting mid-October, 2026. Data derived from the upcoming IP survey, together with data sets from both Teako's 2026 field program and historical records, will assist with prioritizing high-quality targets for a maiden diamond drill program which is currently expected between late Q4 2026 and Q1 2027.

Highlights

• Teako has completed both its 2026 field program at the Tynset Cu-Zn-Ag VMS project and additional fieldwork at the Venna Cu-Co-Zn VMS project. Both projects are 100-per-cent-Teako-owned and located in the highly-prospective VMS belts of central Norway.
• At Tynset, 115 rock chip samples and 106 handheld SDS hammer drill samples were collected across priority targets and are being prepared for imminent shipment to ALS Laboratories in Sweden for analysis.
• At Venna, 180 rock chip samples were collected and are currently being reviewed and prioritized to determine the final analytical program.
• An IP survey over the Strobekken priority 1 target on the Tynset project is expected to commence in mid-October, 2026, with the combined data sets and historical records intended to refine high-quality drill targets ahead of diamond drilling currently expected between late Q4 2026 and Q1 2027.

About the Tynset and Venna field programs

Investigations comprised detailed geological and structural mapping, together with systematic outcrop sampling for geochemical and spectral laboratory analysis. Alongside the refinement of the geological framework across both projects, the field programs aimed to characterize the style, intensity, and spatial distribution of hydrothermal alteration and mineralization across priority target zones.

At Tynset, the field team investigated the priority 1 Storbekken target area, where the upcoming IP survey will be conducted, as well as conducting first-pass reconnaissance mapping and sampling of the recently added high-priority Nonsvola and Vingelen targets.

The Venna program involved a large-scale lithogeochemical (LGC) sampling campaign that involved the systematic collection of rock chips along traverses over greater than nine kilometres of strike on the Mostadmarka Ironworks trend, as well as covering the Storslatten Conductor target and the newly established Central Tuffite zone. Archived rock chip samples collected from the Sandsve target area in 2025 and samples from the 2026 field program are currently being reviewed and prioritized to determine the final analytical program. When combined with the phase 1 LGC data from 2025 (see company press releases dated Nov. 26, and Dec. 8, 2025), the company believes the results will enable a comprehensive lithogeochemical assessment of the Venna area, guiding future exploration decisions for the project.

All samples taken across Tynset and Venna were entered into the Teako database prior to preparation for shipment to ALS Laboratories in Sweden. The analysis selected varies based on the rock type and purpose of each sample, and analysis times are expected to be around six to eight weeks to receive the full suite of data.

The Tynset project

At the Tynset project, 112 rock chip samples were collected from outcrops and waste dumps over the planned IP survey lines (see company press release dated Aug. 18, 2026). The sampling program was undertaken in order to better assess the nature and prospectivity of the surface geology across the geophysical survey area. The lithogeochemical (four-acid digestion with ICP-MS finish) and spectral (Terraspec and Fourier transform infrared spectroscopy (FTIR)) data expected from the lab will aid the selection and ranking of arising geophysical targets, using indications of prospective stratigraphy, mineralization and hydrothermal alteration to further derisk the drilling of targets in the near future. In addition, three representative mineralized "waste" samples were taken from the historical Vingelen mine site, with the intention of better understanding the base and precious metal potential of this target area.

A pilot study was conducted as part of the field program using a handheld SDS hammer drill to collect a total of 106 pulverized outcrop samples (SDS samples) across the target areas. Of these, 74 SDS samples were collected from Storbekken, 26 from Nonsvola and six from Vingelen. The SDS samples will also be submitted to ALS for spectral data collection. The study is a trial for a time- and cost-efficient methodology to acquire high-quality data that supports the mapping of vital geological features like hydrothermal alteration zones and volcanic stratigraphy. The pilot study had a particular focus on a package of quartz-sericite (plus or minus pyrite) schists which were interpreted to be hydrothermally altered felsic volcanics associated with the Svartasvangen mineral occurrence, with the goal of quantifying the mineral assemblage and apparent intensity of this alteration to vector toward the prospective core of the system.

At Nonsvola, the 26 SDS samples were collected with a focus on similar quartz-sericite (plus or minus pyrite) lithologies, including a trend that was interpreted to be a potential feeder/stringer zone due to the presence of locally abundant rusty veinlets. The historic trial workings at Nonsvola were confirmed to be targeting a layer of massive pyrite with traces of chalcopyrite and sphalerite. The immediate proximity of the Nonsvola SDS samples to this mineralized horizon will help to establish the spectral and geochemical characteristics of proximal hydrothermal alteration zones, improving the company's ability to identify proximal alteration zones at targets like Storbekken. This will be further augmented by the six SDS samples collected from host lithologies sampled from waste dumps at the historical Vingelen mine, which were intended to be representative of different alteration styles that are likely spatially associated with the mineralized horizon(s) at the site.

The Venna project

At the Venna project, a lithogeochemical sampling campaign was conducted to build upon the success the 2025 program. One hundred eighty rock chip samples were collected from key localities and systemically along traverses laid out across the Mostadmarka Ironworks trend and Storslatten targets identified during the 2025 program (see company press releases dated Nov. 26 and Dec. 8, 2025).

A further 52 rock chip samples collected from the Sandsve target area in 2025 have also been retrieved from storage and both batches are currently being reviewed and prioritized to determine the final analytical program.

Certain samples will be selected for complete characterization, most of which were taken from iron formations, a key exhalative marker horizon that may help the company vector toward promising Cu-Zn VMS target areas. The remaining samples will be analyzed using the same lithogeochemical (four-acid digestion with ICP-MS finish) and spectral (Terraspec and FTIR) methods as the samples from Tynset, to screen Venna's most prospective target areas for promising indications of hydrothermal alteration that may have formed around a potential concealed Cu-Zn VMS system.

Key samples and assay data collected over the course of the three campaigns completed to date will also form the basis of two MSc-level research projects at Norges Teknisk-Naturvitenskapelige Universite (NTNU) in Trondheim, which aim to assess the prospectivity of the iron formations across the Mostadmarka ironworks trend and the metallogenic potential of the host volcanic sequence of the Venna district.
