Sun Summit Minerals Corp. (TSXV: SMN,OTC:SMREF) (OTCQB: SMREF) (‘Sun Summit’ or the ‘Company’) is pleased to provide an update from its ongoing project-wide exploration program at the JD Project, Toodoggone Mining District, north-central British Columbia (the ‘JD Project’). Drilling has now commenced with over 5,000 meters of drilling planned.

Highlights:

• Drilling has now started: The drill rig is currently advancing the first hole on the northwestern extent of the Creek Zone. Up to 3,000 meters of drilling is planned at the Creek Zone designed to investigate the extent and continuity of near-surface, high-grade and bulk-tonnage gold mineralization. Historical and recent highlight intercepts include:

  • 122.53 m of 2.11 g/t Au including 1.5 of 121.0 g/t Au (CZ-24-004⁷)

  • 54.95 m of 2.69 g/t Au including 19.50 m of 7.31 g/t Au (CZ-24-005⁸)

  • 22.0 m of 11.7 g/t Au including 4.0 m of 61.2 g/t Au (CZ97-008⁵)

• Up to 2,000 meters of drilling planned at the Finn Zone to be completed following the Creek Zone drilling: Holes are designed to evaluate the extent and continuity of high-grade and bulk-tonnage gold mineralization. Historical highlight intercepts include:

  • 35.7 m of 7.26 g/t Au including 1 m of 215.4 g/t Au (JD95-047²⁾

  • 25.9 m of 6.42 g/t Au including 6.1 m of 12.8 g/t Au (JD94-015¹)

  • 22.0 m of 6.32 g/t Au including 12.6 m of 10.8 g/t Au (JD12-003³)

• Project-wide exploration activities focused on drill target refinement are ongoing, including:

  • Over 20-line km of induced polarization (IP) geophysics has been completed along the JD Porphyry Trend.

  • Over 1,000 soil samples have now been collected across the Belle South grid, the southern extent of the JD Porphyry trend.

  • Geological mapping and prospecting are ongoing with a current focus on McClair Creek which transects the JD Porphyry Trend. Mapping has also been completed along the Finn to Creek Corridor as well as the Oxide Peak West target.

‘It’s exciting to see the drill rig turning on the first hole of our fully funded $6 million exploration program,’ said Niel Marotta, CEO of Sun Summit Minerals. ‘This year’s campaign is focused on advancing and expanding the Creek and Finn gold-silver targets, while also generating and refining new priority targets across the JD Project. With several large regional programs underway in the northern Toodoggone, we expect a steady stream of news throughout the season, including drill results from our own aggressive 5,000 metre program.’

JD Exploration Program

The primary exploration goals at the JD Project are to advance and expand the Creek and Finn gold-silver targets and to generate and refine new priority targets across the project. Work is currently focused on the highly prospective 4.5 km long epithermal-related Finn to Creek corridor, as well as the 12 km long JD Porphyry trend (Figure 2).

Drilling update: Drilling has now commenced with the rig advancing the first hole of the program at the Creek Zone. Up to 3,000 meters of drilling is planned at the Creek Zone with holes designed to investigate the extent and continuity of near-surface, high-grade and bulk-tonnage gold mineralization (e.g., 122.53 m of 2.11 g/t Au including 1.5 of 121.0 g/t Au in CZ-24-004⁷ and 22.0 m of 11.7 g/t Au including 4.0 m of 61.2 g/t Au in CZ97-008⁵_, Figure 3). Following completion of the Creek Zone holes, the drill rig will move to the Finn zone where up to 2,000 meters of drilling is planned with holes designed to evaluate the extent and continuity of near-surface high-grade and bulk-tonnage gold mineralization (Figure 4).

Target generation update: Project-wide exploration activities aimed at target generation and drill target refinement are ongoing, including:

• Over 20-line km of induced polarization (IP) geophysical surveying has been completed along the JD Porphyry trend east of the Finn Zone. Additional surveying is planned across parts of the Finn to Creek corridor to infill historical gaps.
• Over 1,000 soil samples have now been collected across the Belle South grid, southern extent of the porphyry trend (Figure 2). Once complete, sampling will continue across the Kadah grid which covers a highly prospective area south of the Finn to Creek corridor lacking historical soil coverage.
• Geological mapping and prospecting are ongoing with a current focus on McClair Creek which transects the JD Porphyry trend. Mapping has also been completed along the Finn to Creek corridor as well as the Oxide Peak West target. Mapping will continue east towards the East McClair target (Figure 2).

Timeline: Drilling and complementary exploration activities are anticipated to continue into September.

Stallion Uranium Corp. (the ‘ Company ‘ or ‘ Stallion ‘ ) (TSX-V: STUD ; OTCQB: STLNF ; FSE: FE0) is pleased to report the results from the 3D inversion of ground gravity data over the Coyote Target, located within the Southwestern Athabasca Basin Joint Venture (‘ JV ‘) Project in partnership with Atha Energy Corp. (‘Atha Energy’) (TSX-V: SASK) .

‘The inversion modelling at Coyote has delineated a laterally extensive and coherent gravity low, spatially coincident with a structurally complex corridor exhibiting attributes characteristic of fertile uranium-bearing systems within the Athabasca Basin,’ said Matthew Schwab, CEO of Stallion Uranium Corp. ‘The robustness of the geophysical anomaly, in conjunction with the structural and lithological setting, provides compelling evidence supporting Coyote as a high-priority target for drill testing.’

  Highlights:  

• 3D gravity inversion completed and interpreted by leading geophysical experts specializing in the Athabasca Basin

 

• Identified multiple gravity-low anomalies along a major conductive corridor

 

• A prominent, coherent gravity-low feature interpreted as a zone of alteration along an interpreted structural corridor

 

• Strong correlation between the gravity anomalies and conductive breaks identified from the MobileMT survey

 

The inversion results highlight a gravity-low anomaly commonly associated with significant uranium mineralization systems in the Athabasca Basin. The modelled anomaly defines the low-density feature’s depth extent, shape, and continuity, further supporting the potential for large-scale uranium alteration at Coyote.

‘The 3D gravity inversion provides a powerful validation of the overall prospectivity at Coyote,’ said Darren Slugoski, Vice President, Exploration at Stallion Uranium. ‘The inversion highlights a series of at least five compelling targets within an 8.5 km corridor. We are well-positioned to take the next steps toward discovery with a subsequent ground EM survey (currently being interpreted by Convolutions Geoscience) in addition to a focused and systematic drill program.’

The inversion results visualize subsurface density variations, with the anomaly’s geometry and intensity suggesting prolonged fluid movement and alteration; critical vectors toward uranium mineralization. The alignment of the gravity-low with previously defined conductive trends and interpreted structural corridors underscores a compelling geological model. The results validate the exploration strategy at Coyote and refine the prioritization of drill targets based on integrated geophysical and structural frameworks.

‘The 3D gravity inversion model at Coyote reveals a well-defined low-density anomaly that is both laterally extensive and vertically continuous,’ said Kyle Patterson, P. Geo., Principal Geophysicist at Convolutions Geoscience, a leading consulting firm specializing in advanced geophysical modelling and geologic integration. ‘This type of geophysical signature is commonly associated with deep-seated structural zones and extensive hydrothermal alteration; both key indicators in targeting basement-hosted uranium deposits in the Athabasca Basin. The spatial correlation with interpreted MobileMT conductors, observed alteration patterns, and interpreted shear zones further support the interpretation that the Coyote project hosts the ideal geological pathfinders for a significant uranium system.’

  About Kyle Patterson:  

Kyle Patterson, P. Geo., is the Chief Geophysicist and founder of Convolutions Geoscience, a geophysical consulting firm specializing in advanced modelling and interpretation techniques for mineral exploration. With over 15 years of experience in the industry and a focus on high-resolution geoscientific data integration in the Athabasca Basin, Kyle has worked extensively with uranium explorers to define and refine targets using gravity, magnetics, and EM inversion modelling. His expertise is in interpreting complex structural and alteration systems, bridging geophysics with geological understanding to drive discovery-focused exploration.

  Gravity Data Inversion:  

Convolutions Geoscience inverted the ground gravity data, utilizing industry-standard 3D inversion techniques to estimate subsurface density variations from the processed gravity data. The objective was to assist in delineating alteration zones of interest for uranium exploration.

Convolutions Geoscience carried out a 3D inversion of the gravity data to create a voxel product of subsurface density anomalies using the industry-standard Fullagar Vertical Prism Magnetic and Gravity (VPmg) codes. The inputs into the inversion were the free air anomaly from the dataset; lake bathymetry data for water depth; digital terrain model (DTM) for the project area, in addition to NASA Shuttle Radar Topography Mission (SRTM) data for surrounding areas; and density constraints for sandstone cover rocks above the unconformity as well as basement rocks below the unconformity. Convolutions created a VPmg gravity inversion using 40m x 40m surface XY blocks and Z blocks of 10m at the surface, increasing by 5% at depth. The total model block depth exceeds 10km.
