Miata Doubles Mineralized Footprint at Jons Trend with a 500m Step Out in Hole 039 and Highlights 54 m at 1.04 g/t Au in Hole 043

Rhea-AI Summary

Miata Metals (OTCQB: MMETF) reported drill results from the Jons Trend at the Sela Creek gold project in Suriname on Dec 10, 2025. New assays confirm continuous gold mineralization across a 750 m by 250 m corridor to 200 m depth and a 500 m step-out in hole 25DDH-SEL-039 that the company says more than doubled the known mineralized footprint. Notable intercepts include 54.0 m at 1.04 g/t Au (25DDH-SEL-043), 53.6 m at 0.84 g/t Au (25DDH-SEL-038) and 4.9 m at 4.04 g/t Au (25DDH-SEL-039).

Key Terms

g/t au, turbidite, shear zone, fire assay, +4 more

8 terms

g/t au technical

"Highlights 54 m at 1.04 g/t gold and 3.4 m at 1.12 g/t gold"

g/t Au stands for grams per tonne of gold and measures how much gold is contained in one tonne of rock or ore. Investors use it like a yield rate: higher g/t Au means more gold recovered from the same amount of material, which usually improves a mine’s revenue potential and lowers production cost per unit of metal. Think of it as the sweetness level of fruit—more sugar per piece makes each piece more valuable.

turbidite technical

"within a thick turbidite sequence. Turbidite sequences tend to be homogeneous"

A turbidite is a layer of sediment deposited by a fast-moving underwater avalanche of mud, sand and rock fragments, often on the slopes of continental shelves and submarine canyons. Think of it like a slushy that pours down a hill and leaves stratified layers; for investors in energy or mining, turbidite formations can host concentrated pockets of oil, gas or minerals and so influence where companies drill and how they value exploration targets.

shear zone technical

"including the steeply dipping Central Guyana Shear Zone continue to 1500m depth"

A shear zone is a band of rock that has been intensely deformed and broken by sideways motion, producing fractures, displaced layers and altered material over a measurable width. For investors in mining and exploration, shear zones matter because they often channel mineral-bearing fluids or concentrate metals, so they can indicate where ore is likely to be found, affect how much resource can be recovered and influence drilling strategy, costs and project risk.

fire assay technical

"prior to analysis using a 50 g fire assay (50 g aliquot)"

Fire assay is a laboratory process used to accurately measure the amount of precious metals, like gold or silver, in a sample of ore or material. It involves heating the sample intensely to separate the metals from other substances, much like melting and purifying metal to determine its purity. This method is important to investors because it provides precise data on the metal content, helping to assess the value of mining operations or mineral deposits.

atomic absorption (aa) technical

"fire assay (50 g aliquot) with an Atomic Absorption (AA) finish"

A laboratory technique for measuring the amount of a specific metal or element in a sample by shining light through vaporized atoms and seeing how much light is absorbed. Think of it like using a tinted lens to tell how much dye is in water: the darker the tint, the more of that element is present. Investors care because results affect product quality, regulatory compliance, resource estimates, and costs in industries that handle metals, chemicals, or environmental testing.

gravimetric finish technical

"over 5.0 grams per tonne (g/t), another cut was taken ... gravimetric finish"

A gravimetric finish is a precise way of measuring the final weight of a product or material after processing or manufacturing. It ensures that the final amount meets exact standards, similar to weighing ingredients carefully in cooking. For investors, it indicates attention to quality control and consistency, which can impact a company's reputation and product reliability.

qualified person regulatory

"Qualified Person as defined under the definitions of National Instrument 43-101"

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

national instrument 43-101 regulatory

"as defined under the definitions of National Instrument 43-101 – Standards"

National Instrument 43-101 is a set of rules and guidelines that govern how mineral exploration and mining companies must report information about their projects. It ensures that the details shared with investors are accurate, consistent, and reliable—similar to how a detailed, verified blueprint ensures a building’s safety. This helps investors make informed decisions based on trustworthy information about a company's mineral resources.

VANCOUVER, British Columbia, Dec. 10, 2025 (GLOBE NEWSWIRE) -- Miata Metals Corp. (CSE: MMET) (FSE: 8NQ) (OTCQB: MMETF) (“Miata” or the “Company”) is pleased to announce further drill results from the Jons Trend Zone at its Sela Creek Gold Project (“Sela Creek” or the “Project”) in Suriname.

Results from holes 25DDH-SEL-037 through 25-DDH-SEL039 and 25DDH-SEL-042 through 25DDH-SEL-046 confirm gold mineralization at Jons Trend across a 750 m by 250 m corridor to a depth of 200 m, remaining open along strike and at depth. Importantly, a 500 m step-out further validates this continuity, more than doubling the known mineralized footprint. Reprocessing of geophysical data indicates the main structures at Sela Creek, which potentially reflect the extent of the gold system, continue to a depth of 1.5 km.

Highlights

• 500 m step-out (hole 25DDH-SEL-039) confirms strike continuity and expands Jons Trend by over 100%, with 4.9 m of 4.04 g/t gold and 13.6 m at 0.80 g/t gold
• Every hole at Jons trend has intersected gold mineralization, with most holes intersecting multiple, subparallel gold-bearing zones
• Continuous gold mineralization now apparent over 750 m x 250 m, open along strike and to depth, an increase in size of over 100 percent
• Drilling continues to return wide mineralized intervals, including:
  • 54 m at 1.04 g/t gold and 3.4 m at 1.12 g/t gold (hole 25DDH-SEL-043)
  • 53.6 m at 0.84 g/t gold (hole 25DDH-SEL-038)
  • 18.9 m at 1.01 g/t gold and 5.4 m at 2.29 g/t gold (25DDH-SEL-044)
  • 9 m at 0.79 g/t gold and 16.5 m at 0.83 g/t gold and 4.4 m at 3.13 g/t gold (25DDH-SEL-045)
  • 34 m at 1.05 g/t gold and 12 m at 1.15 g/t gold hole (25DDH-SEL-046)
• 10,061 metres drilled in 2025, completing the annual target, with results from 2,755 metres pending

“The drilling at Jons Trend continues to deliver significant mineralization across a large footprint that is entirely open, which supports the potential for a future open-pit resource at Sela Creek,” stated Dr. Jacob Verbaas, CEO of Miata Metals. “With all drill holes at Jons Trend across a 750 by 250 metre corridor returning mineralized intercepts, Jons Trend is rapidly emerging as the first major zone of mineralization on the project. We are just starting to grasp the extent of this target.

“Equally important, our ongoing work across the Sela Creek property allows us to define the project-scale controls on gold mineralization. We expect to accelerate our discovery-focused program in Q1 2026 with a fully funded two-rig program, which will allow us to work multiple prospects in parallel. Several prospects are drill-ready and primed for discovery. Our objective in 2026 is to demonstrate that Sela Creek is the next major gold district in Suriname.”

A Robust and Expanding Gold System

Drilling at Jons Trend continues to deliver wide, consistent intervals of gold mineralization hosted in strongly deformed quartz-pyrite-pyrrhotite veining within a thick turbidite sequence. Turbidite sequences tend to be homogeneous and laterally very continuous. This continuity is apparent in the grade distribution such as in hole 25DDH-SEL-046 (fig 3) as well as the strike length which is currently 750 m and open. Overall, Jons Trend is emerging as a large bulk-tonnage prospect that is potentially amenable to open-pit mining. Implicit grade shell modeling (fig 1 & 2) indicates repeated zones of south-easterly plunging mineralization.

Continuity Confirmed by 500 m Step-Out

The results include hole 25DDH-SEL-039, a 500 m step-out that extends the mineralization of Jons Trend over 750 m (FIG 1). Hole 25DDH-SEL-039 yielded 4.9 m at 4.04 g/t gold (fig. 4) and 13.6 m at 0.8 g/t gold in separate intervals. Several holes were drilled in between the main discovery zone and 25DDH-SEL-039 to confirm the continuation of Jons Trend. Jons Trend so far has been drilled to an average depth of 134 m and remains open to depth and along strike.

Magnetic Data Implies Continuity to Depths of over 1 km

An inversion of the magnetic data indicates that the main structures on Sela Creek, including the steeply dipping Central Guyana Shear Zone continue to 1500m depth. The Central Guyana Shear Zone is a dominant project-scale gold control that runs the length of the Sela Creek concession. Given that the structural controls are indicative of the fluid system on Sela Creek the Company believes that gold mineralization may continue to these depths.
