Skyharbour Announces ANT Survey Prior to Upcoming Drill Program as well as Summary of

2024 Drilling to Date at Russell Lake Uranium Project, Northern Saskatchewan

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

SC1P) (the “Company”) is pleased to announce that it has carried out an Ambient Noise Tomography

(ANT) survey prior to the upcoming fall drill program, and has received the remaining results from

the second phase of the program earlier this year at the 73,294 hectare Russell Lake Uranium

Project (“Russell” or the “Project”). The Project is 51% owned by Skyharbour as operator, with joint-

venture partner Rio Tinto Exploration Canada Inc. (“RTEC”) owning the other 49%. It is strategically

located in the central core of the Eastern Athabasca Basin of northern Saskatchewan adjacent to

regional infrastructure, including an all-weather road and powerline, allowing for drilling throughout

all seasons.

ANT Survey and Fall Drill Campaign:

In preparation for the upcoming drill program at Russell, Skyharbour has completed an Ambient

Noise Tomography (ANT) survey at the Russell Lake Project. The survey used Fleet Space

Technologies' ExoSphere technology to acquire 3D passive seismic velocity data over the highly

prospective Grayling and Fork target areas, where previous drilling has intersected high -grade

uranium mineralization. The ANT technology has been successfully employed in mapping significant

sandstone and basement structures and associated alteration zones related to hydrothermal fluid s

pathways in the Athabasca Basin.

The results from this survey will be used to further refine drill targets for the fall 2024 drill program at

Russell. Skyharbour is fully funded and permitted for the follow -up fall drill campaign consisting of

approximately 7,000 metres of drilling at its main Russell and Moore Projects, with 2,500 metres of

drilling at Moore and 4,500 metres of drilling at Russell.

Summary of Russell 2024 Winter and Spring Drilling:

Drilling at Russell earlier this year was completed during two separate phases of drilling, with a total

of 5,152 metres drilled in ten holes during the winter and spring of 2024. The first phase of drilling

consisted of a total of 3,094 metres in six holes , which was previously reported, while the second

phase of drilling consisted of 2,058 metres of drilling in four holes. During Phase One, th e best

intercept of uranium mineralization to date on the property was intersected in RSL24-02, which

returned a 2.5-metre-wide intercept of 0.721% U3O8 at a relatively shallow depth of 338.1 metres,

including 2.99% U3O8 over 0.5 metres at 339.6 metres, just above the unconformity in the sandstone.

The mineralization is open in all directions and will be a focus of upcoming drilling. Phase Two drilling

at the MZE (M-Zone Extension) target, approximately 10 km northeast of the Fork target, identified

prospective faulted graphitic gneiss accompanied by anomalous sandstone and basement

geochemistry. All processing of the core has been completed, and geochemical results have now

been obtained for all drill holes.

Phase One Winter Drilling at Russell:

The first phase of drilling focused on drill testing the newly identified Fork Target area related to and

south-southwest of the Grayling Zone. One hole during Phase One was drilled to test an East

Grayling target, approximately 3 kilometres to the southeast of the Fork Target area. Results of this

first phase of drilling are detailed in Skyharbour’s news release dated July 19th, 2024 , titled :

“Skyharbour Drills New Discovery at Russell Project with High-Grade Uranium Mineralization Up to

3.0% U3O8 at Newly Identified Fork Zone”.

The highlight of the drilling in Phase One was hole RSL24-02, which tested a separate northeast- to

east-trending conductor at the Fork Target area and intersected significant mineralization in the

sandstone near the unconformity. The hole returned 0.721% U3O8 over 2.5 metres between 338.1

and 340.3 metres depth, including 2.99% U3O8 over 0.5 metres between 399.6 and 340.6 metres.

The mineralization is open in all directions. The basement rocks consisted of strongly graphitic pelitic

gneisses accompanied by pegmatite, calc-silicate, and locally radioactive chloritized graphitic shears

and fault zones throughout. The mineralized zone in RSL24-02 was highly enriched in Pb (≤4,120

ppm Pbtotal), Zn ( ≤3,120ppm Zntotal), and other pathfinder elements, while l ocal graphitic faults

throughout the basement rocks intersected strongly anomalous V (≤1380 ppm Vtotal), Zn (≤1320 ppm

Zntotal), Ni (≤983 ppm Nitotal), and Cu (≤618 ppm Cutotal).

Map-NR-new-002.jpg

As previously reported, follow-up drilling both down dip and 175 metres along strike to the west of

RSL24-02 in holes RSL24-04 and -05 intersected prospective sandstone and basement geology and

significant uranium and pathfinder geochemistry. Hole RSL24-04 deviated significantly and missed

the intended target.

Phase Two Spring Drilling at Russell:

During the second phase of drilling at Russell Lake, three holes totaling 1,649 metres (holes RSL24-

07 to -09) were drilled at the regional MZE target area, approximately 10 km northeast of the Fork

target. Holes RSL24-07 and -08 were drilled to completion, while hole RSL24-09 was abandoned

approximately 70 metres above the unconformity due to faulted ground conditions. The final hole of

the second phase of the 2024 winter/spring drilling program, RSL24-10, was drilled at the Fork target

area but missed the primary target due to excessive deviation during drilling.

The MZE target lies on trend from Denison’s Wheeler River Project M-Zone, where historical drilling

intersected significant uranium mineralization. More recent drilling by Denison in 2020 at the M-Zone

encountered additional uranium mineralization with significant faulting, core loss, geochemical

anomalies, and radioactivity. Like the Grayling Zone, the mineralization at M -Zone is hosted by a

graphitic thrust fault within a significant magnetic low. It is also noted that lineaments (cross

structures) associated with Denison’s Phoenix and Gryphon uranium deposits may trend onto the

Russell Lake property within the MZE target area, further enhancing the prospectivity of this target.

002.jpg

Hole RSL24-07 was drilled to test the northern extension of a magnetic low hosting the MZE Zone.

A moderate to strongly bleached sandstone column was intersected down to a silicified and

brecciated unconformity at 506.4 metres. Basement rock consisted of strongly chloritic, hematized,

and clay-altered, paleoweathered pelitic gneiss and granitic pegmatite to 531.0 metres, containing a

clay-altered and chloritic fault gouge at 526.6 to 531.0 metres. Interlayered moderately to strongly

silicified granitic pegmatite and biotite-rich pelitic gneiss are present throughout the remainder of the

hole. The sandstone column returned mostly background geochemistry, aside from anomalous As

(12.9 ppm Aspartial) in a composite sample at a depth of 70 -80 metres. The basement geochemistry

returned anomalous U (≤124 ppm U total and prospective U/Th ratios ≤6.89) at the lower contact of a

faulted pelitic gneiss, in addition to anomalous B (≤2,180 ppm B) within pegmatites and structurally

disrupted, weakly graphitic metasediments.

Hole RSL24-08 tested the northwestern extension of the MZE Zone. Strongly bleached sandstone

with minimal visible structures was drilled until the intersection with the unconformity at 510.9 metres.

Below the unconformity, purple, hematized, chloritized, and paleoweathered graphitic pelitic gneiss

was intersected until 533.3 metres. Intensely chloritized, clay-altered, weakly radioactive pegmatite

with graphitic pelitic gneiss lenses was observed down to 546.6 metres, followed by a steeply faulted

pelitic gneiss with chlorite/clay alteration occurring to 557.5 metres. Mixed pelitic gneiss and granite

extended through the remainder of the hole. The PIMA SWIR spectroscopy results indicated that the

basal 90 metres of sandstone is strongly illitic, which is considered highly prospective for uranium

mineralization. Background sandstone geochemistry was present until 10.0 metres above the

unconformity, with the sandstone below 500.0 metres anomalously enriched in B (≤774 ppm B). The

boron anomaly is related to the presence of dravitic clay as identified in the correspondin g PIMA

data. The basement returned highly anomalous U (≤394 ppm U total) accompanied by anomalous B

(≤607 ppm B), within an interval of strongly argillized, weakly graphitic pelitic gneiss. The basement

samples with the highest U contents also have high U/Th ratios (≤18.76), which suggests the uranium

is of hydrothermal origin.

Hole RSL24-09 was drilled to test the MZE conductor and McDougall Fault at the unconformity

southwest of the 2011 MZE holes. RSL24-09 was lost at 432.0 metres (approximately 60 to 70

metres above the expected unconformity) within strongly bleached, moderately desilicified/friable

sandstone. Variably bleached and desilicified sandstone was intersected throughout, hosting

multiple small fracture zones. While the sandstone geochemistry returned values within background

levels, a highly prospective illitic clay signature was present from 385.0 metres until the end of

the hole.

Russell Lake Project Historical Summary:

The Russell Lake Project is a large, advanced -stage uranium exploration property totalling 73,294

hectares strategically located between Cameco’s Key Lake and McArthur River Projects and

adjoining Denison’s Wheeler River Project to the west and Skyharbour’s Moore Uranium Project to

the east. The northern extension of Highway 914 between Key Lake and McArthur River runs through

the western extent of the Property and greatly enhances accessibility, while a high-voltage powerline

is situated alongside this road and the western edge of the property south of Key Lake. Skyharbour’s

acquisition of Russell Lake creates a large, nearly contiguous block of highly prospective uranium

claims totalling 108,999 hectares between the Russell Lake and the Moore uranium projects.

There has been historical exploration carried out at Russell Lake. However, most of it was conducted

before 2010, prior to the discovery of several major deposits in and around the Athabasca Basin. In

2023, Skyharbour’s inaugural diamond drilling program tested several Fox Lake Trail targets and the

Grayling Zone. Significant uranium mineralization was intersected in the majority of holes at the

Grayling Zone over a strike length exceeding one kilometre. Drill hole RSL23-01 intersected one of

the better drill results from the project, returning a 5.9 metre wide intercept of 0.151% U3O8 at a depth

of 338.4 metres, which include d 1.0 metres of 0.366% U 3O8 at 343.3 metres depth within a thrust

wedge.

Several notable exploration targets exist on the property , including the Grayling Zone, the M -Zone

Extension target, the Little Man Lake target, the Christie Lake target, the Fox Lake Trail target and

the newly identified Fork Zone target . More than 35 kilometres of largely untested prospective

conductors in areas of low magnetic intensity also exist on the Property.

QA/QC:

All drill intervals above are downhole length s. S ampling procedures and QA/QC protocols for

geochemical results are as follows. All drill core samples selected for analysis are shipped to the

Saskatchewan Research Council Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan ,

under the care of Skyharbour personnel, for preparation, processing, and multi-element analysis by

ICP-MS and ICP -OES using total (HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by

fusion, and U3O8 wt. % assay by ICP-OES using an ISO/IEC 17025:2017 accredited method. Assay

samples are primarily chosen based on downhole probing radiometric equivalent uranium grades

and scintillometer (Radiation Solutions RS -125) peaks, with additional samples taken above and

below the unconformity and covering structures and alteration of interest in both the sandstone and

basement. All assay sample intervals comprise 0.5-metre metres of continuous half-core split in the

field using a manual core splitter; one half of the split core is retained in the core box, while the other

half is sent to SRC for geochemical analysis. In addition to sampling all mineralization, at least one

to two shoulder samples (each 0.5 metre wide) are collected both above and below any mineralized

interval. Mineralized and shoulder samples may additionally be selected for density determination

using the lost wax method at SRC. Skyharbour also collects systematic composite samples in the

sandstone, for which small chips of core are collected at the end of every row of core in the core box

over a 10 m etre wide interval and combined into one sample before being sent to the SRC for

analysis. The systematic sandstone samples are then analyzed by the same analytical methods

previously described for the assay samples. SRC is an ISO/IEC 17025/2005:2017 accredited and

Standards Council of Canada certified analytical laboratory. Blanks, certified standard reference

materials, (including high -grade uranium standards) , and sample repeats are inserted into the

sample stream at regular intervals by both Skyharbour and SRC in accordance with Skyharbour’s

quality assurance/quality control (QA/QC) procedures. Geochemical assay data are subject to

verification procedures by qualified persons employed by Skyharbour prior to disclosure. Skyharbour

also carries out sampling for clay minerals analysis, which involves collecting a 3-5 cm wide piece of

core at the desired sample depth . Samples are taken systematically every 10 metres in the

sandstone, with selected samples also being taken in areas of prospective alteration. These samples

are then transported by Skyharbour personnel to Rekasa Rocks Inc. in Saskatoon, Saskatchewan,

where they are analyzed by Short Wavelength Infrared Reflectance (“SWIR”) using a Portable

Infrared Mineral Analyzer (“PIMA”) to determine the clay species present in the sample and their

relative proportions. Several samples from each batch of samples are subject to repeat analysis by

Rekasa in accordance with Skyharbour’s quality assurance/quality control protocols.
