Jons Trend-Big Berg Corridor:

Article content

Drilling continues to define high-grade gold mineralization within the Jons Trend-Big Berg corridor, an approximately 1,300 m mineralized trend that remains open laterally and to depth. Jons Trend consists of steeply dipping vein zones at shallow depth that trend northwest-southeast which are characterized by broad mineralized intervals that contain high-grade zones.

Jons Trend Drilling:

Hole 26DDH-JT-019 was drilled from the centre of Jons Trend and directed northwest to test the down-dip extension of high-grade mineralization previously intersected in 26DDH-JT-008, which intersected 31.75 m at 4.62 g/t Au including 23.75 m at 5.73 g/t Au.

The highlight interval in JT-019 is hosted in tightly folded quartz-biotite schist with strong silica, chlorite and biotite alteration. Mineralization is associated with dense sheeted shear veining and foliation-parallel extensional quartz veins containing approximately 1% sulfides, including pyrite and pyrrhotite, and locally visible gold.

These results continue to support the interpretation of Jons Trend as a stacked, structurally controlled gold deposit, with high-grade zones developing within broader mineralized intervals. The result also reinforces Miata’s improving understanding of the controls on mineralization at Jons Trend, which continues to support ongoing drill planning across the broader Sela Creek Project.

Big Berg Drilling:

Article content

The latest Big Berg drilling consisted of step-out holes 26DDH-BB-011 to BB-013. Holes BB-011 and BB-012 were drilled southeast of the main Big Berg discovery area, stepping out approximately 150 m and 75 m, respectively. Hole BB-013 was drilled approximately 150 m west of the main discovery area toward Jons Trend and was designed to test the potential continuation of mineralization between two zones.

Article content

The highlight intervals from the Big Berg step-out drilling are characterized by strong strain zones within crenulated quartz-garnet-biotite schist, hosting thick extensional quartz-biotite-chlorite veins. These veins contain visible gold with minor sulphides, generally less than 0.5%.

Article content

The result from BB-013 extends meaningful mineralization approximately 150 m west of the main Big Berg discovery area toward Jons Trend and provides further support for Miata’s interpretation that the two zones form part of the same broader mineralized corridor.

To date, in 2026, Miata has completed approximately half of its planned 25,000 m drill program at Sela Creek, with drilling continuing across multiple targets including Jons Trend, Big Berg, Puma West, Stranger, Cambior and Golden Hand. Results remain pending for several recently completed holes.
