NEWS RELEASE

Skyharbour Announces Drilling Underway and Renewed Permit at the High-Grade Moore

Lake Uranium Project, Saskatchewan

Vancouver, BC - Skyharbour Resources Ltd. (TSX-V: SYH) (OTCQX: SYHBF) (Frankfurt:

SC1P) (“Skyharbour” or the “Company”) is pleased to announce that drilling is underway for the

first phase of the campaign this year at its 100%-owned, 35,705 hectare Moore Uranium Project

(“Moore” or the “Project”), located approximately 15 kilometres east of Denison Mines ’ Wheeler

River project in the eastern Athabasca Basin, Saskatchewan . Skyharbour has also received a

renewed three-year drill permit at the Project valid through March 2029.

Skyharbour has commenced its multi-phased 2026 drill campaign at Moore, which is planned to

total 8,000 to 10,000 metres of diamond drilling at the Maverick Trend and other regional targets.

The Phase I program that is underway is expected to consist of approximately 4,000 to 5,000

metres in 10 to 12 drill holes.

The Company recently completed 58.3 line -kilometres of ground Step Loop Transient

Electromagnetic (“SLTEM”) survey coverage earlier this year , extending existing ground

geophysical coverage by 2 kilometres to the southwest along the broader 12 -kilometre-long

Maverick Trend. This structural corridor coincides with intense hydrothermal alteration and

structural disruption intersected during 2025 exploration drilling at the new Nomad target. The

survey refined existing targets and delineated additional EM conductors for drill testing along the

interpreted Nomad structural trend. In parallel with field activities, Skyharbour has also engaged

SMCG Services to undertake advanced data integration and AI-assisted prospectivity modelling

to further refine and prioritize drill targeting across the Moore Project.

This Phase I drilling program is initially focused on the Nomad Zone where drilling is testing priority

gravity anomalies and newly delineated EM conductors along the Nomad structural corridor.

Follow-up drilling is also planned at the Esker target area to the northeast where the Company

will evaluate the potential strike extension of mineralization intersected in historical drill hole ML-

165, which returned 1.21% U3O8 over 0.5 metres at the unconformity.

In addition, this phase of drilling will include expansion drilling at the Maverick Zones, targeting

the largely untested basement-hosted potential associated with previously intersected high-grade

mineralization. Drilling is also planned at the Nutana target where historical drilling inter sected

strong dravite alteration and graphitic basement conductors that remain inadequately tested due

to wide drill spacing.

Target Zone Summaries:

The Nomad Zone was identified in 2025 following the reprocessing and reinterpretation of a

historical 2005 ground gravity survey, which outlined a previously unrecognized structural corridor

along the broader Maverick Trend. The zone lies approximately 1.7 kilometres west-southwest of

the Main Maverick Zone along the interpreted Maverick structural corridor, and prior to 2025 the

area had seen very little drilling. Drilling completed in 2025 intersected strongly faulted, desilicified

and locally silicified sandstone above the unconformity, and intensely altered basement rocks

below, including pervasive silicification and hematization of pelitic gneiss and localized graphitic

units.

Results from the 2025 program at Nomad confirmed the presence of a broad, structurally

controlled hydrothermal system characterized by pervasive faulting, strong clay alteration, and

significant silicification affecting both sandstone and basement lithologies. The scale and intensity

of alteration, toge ther with associated conductors, indicate a fertile corridor analogous to that

hosting mineralization at Maverick. Both unconformity and basement -hosted targets remain

largely untested along strike to the southwest.

The Esker Zone target is located approximately 3 kilometres northeast of Maverick along the

same interpreted structural corridor. Historical drill hole ML -165 returned 1.21% U3O8 over 0.5

metres at the unconformity. Historical drilling encountered graphitic conductors with pronounced

faulting, and clay–hematite alteration characteristic of unconformity-related uranium systems. The

northeast strike extension of the ML -165 mineralization remains largely untested beneath lake

cover. The Phase I 2026 drill program will test prioritized EM and resistivity anomalies interpreted

to lie along strike of the ML-165 mineralized structure, as well as untested conductors northeast

along trend.

The Nutana Zone is situated within a structurally controlled corridor proximal to Maverick and

remains relatively underexplored. Historical drilling intersected multiple graphitic conductors

below the unconformity, accompanied by strong bleaching, localize d limonitic sandstone

alteration, and strong dravitic clay development. Dravite is widely regarded as a proximal

alteration mineral in Athabasca Basin uranium systems and is commonly associated with both

unconformity and basement-hosted high-grade uranium deposits throughout the basin.

Basement lithologies at Nutana consist of structurally disrupted pelitic to granodioritic gneisses

with quartz flooding, and extensive shearing. Weakly elevated radioactivity and fault -controlled

alteration confirm an active hydrothermal system. Historical drilling tested this corridor with wide

spacing, and structural and geophysical characteristics indicate mineralization potential along

strike.

Data Integration and Targeting Enhancement Using AI:

Skyharbour has engaged SMCG Services, led by Drew Heasman, a geoscientist and data

scientist specializing in advanced mineral targeting and integrated exploration analytics. Mr.

Heasman is an internationally recognized award recipient, including the 2024 F uture Explorers

Challenge (Dundee Precious Metals / Humyn.ai) and the 2022 Frank Arnott: Next Generation

Explorers Award.

At the Moore Project, SMCG Services will undertake regional - to project -scale prospectivity

mapping and data -driven anomaly detection, integrating geological, geochemical, geophysical,

structural, and PIMA clay mineral data into a unified targeting framework. The objective is to

systematically identify and prioritize exploration trends and under -evaluated target areas across

the broader Maverick Trend and associated structural corridors. This work will complement

ongoing drilling and geophysical programs and is designed to enhance targeting efficiency and

support future drill campaign planning.

Moore Uranium Project Overview:

In June 2016, Skyharbour secured an option to acquire Denison Mine's Moore Uranium Project,

on the southeastern side of the Athabasca Basin, in northern Saskatchewan and has since fulfilled

its earn-in. The project consists of 12 contiguous claims totaling 35,705 hectares located 42

kilometres northeast of the Key Lake mill, approx. 15 kilometres east of Denison’s Wheeler River

project, and 39 kilometres south of Cameco’s McArthur River uranium mine. Unconformity-hosted

uranium mineralization was discovered on the Moore Project at the Maverick Zone with historical

drill highlights consisting of 4.03% eU3O8 over 10 metres, including 20% eU3O8 over 1.4 metres,

in ML-161. In 2017, Skyharbour announced drill results of 6.0% U 3O8 over 5.9 metres, including

20.8% U 3O8 over 1.5 metres at a vertical depth of 265 metres, in hole ML -199. More recently,

2025 drilling at the Main Maverick Zone returned 4.84% U3O8 over 4.4 metres, including 11.77%

U3O8 over 1.6 metres in hole ML25 -15, further confirming the continuity of high -grade

unconformity-related mineralization.

In addition to the Main and East Maverick Zones, the project hosts other mineralized targets with

strong discovery potential which the Company plans to test with future drill programs. The project

is fully accessible via winter and ice roads which simplifies logistics and lowers costs. Large

proportions of the property are accessible in the summer as well.
