Skyharbour Resources Ltd . (TSX-V: SYH ) (OTCQX: SYHBF ) (Frankfurt: SC1P ) (‘Skyharbour’ or the ‘Company’) is pleased to announce that partner company Mustang Energy Corp. (‘Mustang’) received the results of a high resolution HTDEM survey at the 914W Uranium Project (the ‘Project’), totaling 136 line-kms. The Project has road access and is in a prospective region known for its mineral potential south of the Athabasca Basin. The 914W TDEM survey successfully defined a well-developed conductive zone within the project. The geometry and strength of the anomaly are consistent with graphitic basement rocks or fault-bound alteration zones, both favorable for unconformity-type uranium mineralization. Mustang Energy may acquire a 75% interest in the Project by issuing common shares having an aggregate value of CAD $480,000, making aggregate cash payments of $275,000 to Skyharbour, and incurring an aggregate of $800,000 in exploration expenditures on the property over a three-year period.

The Xcite helicopter-borne Time Domain Electromagnetic (TDEM) survey was flown by Axiom Exploration Group Ltd. over the Project, covering approximately 136 line-km. The survey simultaneously collected electromagnetic, magnetic, and radiometric data to map conductive, magnetic, and radiometric variations related to prospective uranium-bearing structures. The survey was flown in addition to Mustang’s nearby Spur project TDEM survey.

Early-time channels (0.014–0.045 ms) show strong, high-amplitude EM responses along the east-central portion of the 914W block, indicating shallow conductive zones near surface. This conductor persists through mid-to-late time channels (0.12–0.56 ms) and may represent graphitic horizons or fault-controlled alteration zones, a key uranium pathfinder feature in the Athabasca Basin margin setting. The intensity and continuity of the anomaly diminish slightly with later decay times, consistent with a discrete subsurface conductor rather than surficial noise.

The inversion modelling from 50 m to 350 m depth shows consistent conductive features. From 50 – 150 m the depth slices show a strong, laterally continuous conductive zone trending east-northeast across the east-central portion of the property. The 250 to 350 m depth slices show the conductivity anomaly persists at depth.

2025 914W Soil Sampling Results:

A one-week prospecting and soil sampling program was carried out on claim 914W in May of 2025. In total, 25 rock samples and 142 soil samples were collected. The soil sampling focused on the northwest corner of the property immediately south of the Scurry Rainbow E Zone and the Don Lake Trenches where no outcrop exposure is present. Rock sampling was limited by the scarcity of exposed outcrop across the property.

Although the program did not identify any new significant discoveries, particularly in the southern portion of the Project, the northern soil grid returned anomalous uranium values. In this program, five soil samples from the southern portion of the grid exceeded 4 ppm U, which would be considered slightly elevated.

Prospecting efforts did not confirm elevated uranium values in the southwestern part of the grid, likely due to limited outcrop exposure. However, anomalous uranium values were identified in the northeastern portion of the soil grid, including a granitic gneiss sample that returned 42.3 ppm U.

Sampling Methods:

Samples were submitted to SRC Laboratories in Saskatoon, SK, for analysis. Both rock and soil samples were tested using ICP-MS with four-acid digestion, ICP total four-acid digestion, and U₃O₈ assays by ICP reported in weight percent.

Horizon A soil samples were collected by removing surface vegetation with a trowel and sampling the uppermost layer of topsoil. Rock samples were taken from exposed basement boulders or granitic outcrops that returned elevated counts per second (cps) readings.

914W Property Summary:

The 914W Project consists of one claim covering 1,260 hectares approximately 48 km southwest of Cameco’s Key Lake Operation. Highway 914 runs through the western edge of the project, providing excellent access for exploration. Historical geological mapping of the property and the surrounding area has shown that the project is predominantly underlain by prospective Wollaston Supergroup pelitic and psammitic to arkosic gneisses of the Western Wollaston Domain, which hosts significant unconformity-related uranium mineralization in the Athabasca Basin as well as pegmatite-hosted uranium mineralization elsewhere in the Wollaston Domain.

Despite the project’s proximity to Highway 914 and prospective geology, the project has seen limited modern exploration work. The earliest work on the 914W property included airborne EM and magnetic surveys and ground geological reconnaissance in 1968-1970, lake water and sediment sampling in 1976, ground VLF-EM, magnetic, and radiometric surveys, geological mapping, trenching, as well as sampling on the project and surrounding areas. Immediately to the north of the 914W property, prospecting led to the discovery of the Scurry Rainbow Zone E (SMDI1961) and the Don Lake Trenches (SMDI 1983), where up to 1,288 ppm U was encountered in drill hole ML-1 (SMDI1961) in a pyroxene-rich unit, and surface prospecting revealed up to 0.64% U ₃ O ₈ in a trench at Don Lake Zone E (SMDI 1983). More recently, the project has seen airborne geophysical coverage by helicopter-borne VTEM (southern half) in 2005 and Tempest TDEM (northern half) in 2007, with prospecting, geological mapping, rock/sediment sampling and lake sediment sampling occurring on the project and surrounding areas in 2005-2007. The project remains underexplored and prospective for unconformity-related and pegmatite-hosted uranium and REE’s.

Sranan Gold Corp. (CSE: SRAN) (FSE: P84) (Tradegate: P84) (‘Sranan’ or the ‘Company’) announces significant diamond drill results from the Randy’s Pit target at its Tapanahony Gold Project in Suriname. These results are from the first four drill holes of an ongoing 10,000-metre drill program and confirm that a significant gold system continues in and below the saprolite mineralization (see Figure1).

Initial diamond drilling at Randy’s Pit intersected significant gold in all of the first four holes. The best result was intersected in hole 25RADD-004 and assayed 64.0 metres (m) averaging 3.0 grams per tonne (g/t) gold (Au). This interval included 5 m averaging 33.5 g/t (or 1.2 ounces per ton) Au and 1 m grading 145.4 g/t (or 5.1 ounces per ton) Au. Fine visible gold is dispersed throughout the quartz vein in the interval from 167 to 168 m (see Figure 3).

To date, gold mineralization has been encountered through grab and trench sampling from Randy’s Pit up to 76.6 g/t (see Sranan release dated July 31, 2025) and trenching up to 36.6 g/t over 5 m (see release dated August 7, 2025). Sampling at Poeketi, which is located 3 km to the northwest along the trend of the major shear system from Randy’s Pit, assayed grab samples up to 108 g/t and 84 g/t Au (see release dated May 15, 2025).

Drilling has confirmed multiple high grade and bulk tonnage gold intercepts across a shear system that is at least 150 m wide and is being tested with trenching and drilling. Gold mineralization is present in both the saprolite and in the bedrock beneath and has been intersected in drillholes to at least 120 m in vertical depth (see Figure 2).

All bedrock intercepts exhibit strongly silica-sericite-ankerite alteration in basaltic host rocks that have been sheared into proto-mylonitic to mylonitic rock with grey to white quartz carbonate veins, transposed within the same sheared fabric. Pyrite and pyrrhotite are observed along shear planes, vein selvages as well as within late-stage fractures, which are typical for orogenic gold systems in the Guiana Shield. Intercepts within the saprolite have shown oxidized sulfide box works and sugary veins. All the shear zones are north-northwest striking dipping to the west.

Dr. Dennis LaPoint, EVP of Exploration and Corporate Development, commented: ‘These impressive intercepts are the result of careful geologic and logging observations by Sranan Gold and are the first holes in the evaluation of this significant gold system. The results of hole 25RADD-004 are truly impressive. We will continue to delineate the deformation history and geometry of this major structurally-controlled gold system as we extend drilling along strike and at depth. Drilling has not yet tested below the Randy’s Pit nor the extensions seen in trenching.’

Oscar Louzada, CEO of Sranan Gold, commented: ‘We now have very clear evidence of a well mineralized system in the Randy’s Pit area. We will continue to drill the Randy’s Pit target as well as explore along strike towards the Poeketi target in the near future so we can continuously attempt to determine the gold endowment potential of the 4.5-km-long Randy-Poeketi trend.’

* Intercepts above 0.3 g/t Au with internal dilution up to 5 m. All other intercepts reported are above 0.3 g/t Au with internal dilution up to 3 m. All intervals reflect apparent thickness based on the sample intervals from drill core. All anomalous results are based on the intervals sampled in drill holes. These intervals represent apparent widths or thicknesses that may be wider or thicker than true widths or thicknesses of intervals. As more drilling is completed, Sranan expects to gain better understanding of the relation between mineralized intervals, and the interpretation will be used in future calculations.

Samples were prepared and assayed by Filab in Paramaribo, Suriname. All samples >2 g/t were re-assayed with 50 gm re-assay and gravimetric assay. Standard QA/QC procedures were followed which showed a satisfactory level of reproducibility. The Company notes that the drill intercepts may not represent true underlying mineralization. Core logging, photography and sampling are completed under strict industry standard QA/QC protocols (OREAS-certified reference materials, assayed course blanks, and duplicates of core). An independent lab will be used for confirmation of results.
