Puma is the southern-most target at Sela Creek, and currently encompasses a total of approximately 2.7 km of strike length, and a width of 400 m. Puma is one of several targets identified at the 215 km² property where high-grade gold is mined from shallow pits by small-scale miners, leaving the bedrock unexplored. Recent mining¹ by artisanal operators at Puma have further supported the Company’s targeting efforts and conviction.

Ongoing Generative Exploration

Article content

In parallel with its 10,000-meter drilling campaign, Miata’s technical team continues to evaluate historic and active mining areas across the 215 km² Sela Creek concession. This work includes pit mapping, sampling, and the assessment of artisanal ore¹ piles to better understand vein morphology and mineralogy across the project.

Article content

To date in 2025, the Company has collected 248 surface samples, including a standout artisanal ore sample from the Aplito area assaying 675 g/t Au² shown in figure 5, underscoring the potential for further high-grade mineralization outside of the current targets. The Aplito target area is several km east of camp and will be assessed for follow up exploration. Figure 5 also shows visible gold in a quartz vein from an ore¹ pile sample of the Puma Target.

To build on these efforts, Miata intends to commence a comprehensive stream sediment sampling program focused on the underexplored areas trending toward the Guyana Shield Shear Zone. This initiative will generate over 1,000 samples and aims to vector toward new targets for follow-up exploration.

QAQC

Article content

Grab samples were sent to Filab in Paramaribo, an ISO certified laboratory for 50g aliquot fire assay. Both the Company and Filab insert standards, duplicates and blanks at select intervals, all of which yielded acceptable values. Drill core of hole 25DDH-SEL-018 and 19 will be logged and cut on site prior to analysis at Filab.
