Teako Completes Inaugural Diamond Drilling and Downhole Geophysics at Its Løkken Property and Receives Additional Drill Permit for Its Massive Sulfide Target at Fjellslett

Vancouver, British Columbia--(Newsfile Corp. - May 22, 2025) - Teako Minerals Corp. (CSE: TMIN) (the "Company" or "Teako") announces the completion of an inaugural diamond drill program at its Åmot and Høydal targets both part of its district-scale Løkken copper-cobalt-zinc ("Cu-Co-Zn") volcanogenic massive sulfide ("VMS") project in central Norway (the "Project"). The program comprised one hole at each target for a total of 364 meters (see Figure 1). Results include the intersection of 29.9 m of pyrite- and pyrrhotite-dominated vasskis horizons at Åmot, with the largest single horizon totaling a 20.4 m downhole intersect, interpreted by the Company as a sulphide-rich zone within the middle volcanic member of the prospective stratigraphy. At Høydal, drilling intersected a 4.9 m thick jasper-rich unit; jasper horizons typically occur in close proximity to VMS mineralization in the Løkken district.

Downhole electromagnetic (or "DHEM") surveys were completed for both holes. These surveys, used to detect nearby conductive (sulfide-bearing) bodies, have identified at least two targets requiring further investigation.

Additionally, the Company is pleased to announce that it has secured drill permits for its Fjellslett VMS target, situated west of the former Løkken Mine (see Figure 1). The Fjellslett target is within the part of the Løkken Project, in which the Company acquired a 90% interest from Capella Minerals (TSXV: CMIL) in August 2024. This target hosts outcropping massive sulfide mineralization, and drilling is expected to commence in summer 2025. The drill program, will utilize The Coring Company's sampling technology and is partly funded by Innovation Norway. Further details regarding this program will be issued prior to drilling commencement.

Highlights

• Teako completed an inaugural diamond drill program on the Løkken property. The program was constrained by permitting requirements, necessitating completion by March 31 (Åmot) and April 11 (Høydal).
• Åmot drill hole AM-25-001 (218.6 m) intersected 29.9 m of pyrite- and pyrrhotite-dominated vasskis horizons, with the largest single horizon being a 20.4 m downhole intersect (between 88.5 m and 108.9 m).
• Høydal drill hole HOY-25-001 (145.6 m) intersected a 4.9 m thick jasper unit (from 68.2 m to 73.1 m), which typically occurs in close proximity to VMS mineralization in the Løkken district, plus narrow horizons of vasskis-style mineralization.
• Samples from the sulfide bearing intervals at Åmot will be submitted to a certified laboratory for comprehensive analyses of Cu, Zn, gold (Au), and antimony (Sb) (results pending).
• DHEM surveys completed for both drillholes identified a below-hole EM conductor at the Høydal target and a near edge hit at the Åmot target, with a larger EM signature nearby.
• Phase II drilling is currently expected to be undertaken in late 2025.
• Drill permit granted for the Fjellslett target with drilling expected to commence in summer 2025.

Sven Gollan, Chief Executive Officer, commented; "We are pleased to be announcing the initial observations from the first two diamond drill holes, completed at the Løkken project, both of which confirm the potential for discoveries of new massive sulfide deposits in previously undrilled areas. We look forward to building on the knowledge gained from this drilling and applying this towards an expected phase II drill program in late 2025."
