Miata Intersects 96 m of 1.41 g/t gold in Near-Surface Gold System at Big Berg, Delivering Best Intercept to Date at the Sela Creek Gold Project, Suriname

Initial drilling at Big Berg has returned the strongest intercepts to date at Sela Creek, confirming a broad gold system with consistent mineralization from surface. These results highlight the first large discovery outside of Jons Trend, adding scale to the Project via the drill bit and highlighting its district-scale potential. The scale and geometry of mineralization suggest Big Berg may form part of the same structural corridor as Jons Trend, located app roximately 1 km along strike from Jons Trend, and further drill-testing of this trend and its continuity is ongoing.

Highlights

• 26DDH-BB-003 intersected:

  • 67.5 m at 1.13 g/t Au from surface^1,2

  • and 96 m at 1.41 g/t Au from 96 m^1,3

• Including multiple high-grade zones:

  • 18.1 m at 2.95 g/t Au² from 40.4 m

  • 7.7 m at 5.79 g/t Au² from 130.3 m

  • 4.65 m at 3.98 g/t Au² from 147 m

  • 23.5 m at 2.34 g/t Au² from 168.5 m

• Big Berg is a new discovery, approximately 1 km southeast of Jons Trend

• Continuity of gold mineralization was confirmed in three additional drill holes at Big Berg:

  • 7 m at 3.75 g/t Au² from 96 m in DDH-BB-001

  • 25 m at 0.90 g/t Au² from 69 m, and 5.25 m at 2.38 g/t Au from 105 m in DDH-BB-002

  • 7.25 m at 2.79 g/t Au² from 90.75 m and 7.2 m at 1.99 g/t Au fro m 110.8 m in DDH-BB-04

• Big Berg and Jons Trend remain open along strike and at depth, highlighting significant district-scale expansion potential

• One rig continues drilling at Big Berg to expand discovery zone

“These results from Big Berg mark a defining moment for the Sela Creek Project,” stated Dr. Jacob (Jaap) Verbaas, CEO of Miata. “Intersecting nearly 100 metres of continuous gold mineralization at 1.41 g/t Au in a new target, beginning near surface, is a clear indication that we have found a large and robust gold system. When combined with the higher-grade intervals throughout the hole, this represents the strongest drilling we have seen on the Project to date.”

What is particularly compelling is the strong similarity between Big Berg and Jons Trend. While Jons Trend continues to grow toward what we expect will form the basis of an initial resource, Big Berg demonstrates that mineralization extends beyond a single discovery zone.”

“Both Big Berg and Jons Trend remain open along strike and at depth, and we are well positioned to continue expanding the system and defining its full scale. One of our drill rigs has now returned to Big Berg to continue testin g this exciting new discovery.”

Big Berg Target

Big Berg is situated approximately 800 to 1,200 metres along strike from Jons Trend, within the same interpreted structural corridor that hosts gold mineralization across the central portion of the Sela Creek property. Drilling at Big Berg has confirmed a robust and laterally extensive mineralized system characterized by broad zones of gold mineralization, with local high-grade mineralized zones.

Hole 26DDH-BB-003 is particularly significant, intersecting repeating mineralized zones from surface through to depth, with two major zones that combine to 67.5 m and 96 m respectively. These wide intercepts, combined with multiple higher-grade intervals such as 2.5 m at 15.34 g/t Au from 45 m and 2 m at 17.84 g/t Au from 131.3 m, point to a strong gold system that may be amenable to open-pit mining.

The distribution of mineralization within the hole in dicates the presence of repeating, sub-parallel zones. This hypothesis is supported by cross-section interpretations that highlight vertically continuous zones of veining and mineralization across multiple drill holes.

Core observations show mineralization associated with quartz-sulphide veining within altered host rocks, with increasing silica and muscovite alteration at depth, consistent with a strengthening mineralized system.

Potential Link to Jons Trend and District-Scale Potential

The results from Big Berg have important implications for the broader Sela Creek project.

The proximity of Big Berg to Jons Trend, comb ined with its position along the same interpreted structural corridor, provides strong support for a potentially continuous or repeating mineralized system along strike. This spatial relationship significantly enhances the potential for linking these zones through ongoing drilling.

To date, drilling at Jons Trend has defined a large and growing mineralized footprint that is expected to form the foundation of an initial resource. Big Berg proves that this mineralization is not isolated.

Key similarities between Big Berg and Jons Trend include:

• Comparable vein orientations and structural controls

• Similar alteration assemblages and host lithologies

• Presence of broad mineralized envelopes with internal high-grade zones

• Strong vertical continuity

These characteristics support the interpretation that Big Berg may represent either a direct extension of Jons Trend or a parallel mineralized zone within the same structural framework.

Both Big Berg and Jons Trend remain open in all directions and at depth, with drilling to date testing a limited portion of the interpreted mineralized corridors. This reinforces the Company’s view that Sela Creek represents a large, underexplored gold system with substantial room for continued expansion, both laterally and along strike.

Program Update and Next Steps

The Company is currently drilling additional holes at Big Berg following these results, that are planned to further define the scale and continuity of mineralization.

Ongoing work will focus on:

• Expanding the footprint of mineralization along strike and at depth

• Testing continuity between Big Berg and Jons Trend

• Further refining the structural model controlling gold mineralization

Miata is well-positioned to accelerate both expansion and discovery drilling across multiple high-priority targets, including Puma, Stranger, and additional regional corridors.

QAQC

Drill core samples are analyzed for gold at FILAB Suriname, a commercial certified laboratory under ISO 9001:2015. Samples are crushed and pulverized to 85% passing 88 µm prior to analysis using a 50 g fire assay (50 g aliquot) with an Atomic Absorption (AA) finish. For samples that return assay values over 5.0 grams per tonne (g/t), another cut was taken from the original pulp and fire assayed with a gravimetric finish. Samples with coarse visible gold or returning an assay value over 10.0 grams per tonne (g/t), metallic screen analysis is co nducted on the coarse reject material. Miata Metals inserts certified reference standards, as well as blanks and ¼ core duplicates in the sample sequence for quality control and assurance.
