Skyharbour Partner Company Terra Clean Energy Announces Fraser Lakes B Deposit

Recognized by Government of Canada as Active Rare Earth Deposit

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

SC1P) (“Skyharbour” or the “Company”) is pleased to report that its partner company Terra Clean

Energy Corp. (“Terra”, previously Tisdale Clean Energy) has highlighted the rare earth element

(“REE”) potential at the Fraser Lakes B Deposit, confirmed by drilling and assays. The mineralization

is predominantly uranium and thorium but t he REE component within the deposit and surrounding

areas contains significant quantities of rare earth oxides (“REO”) specifically La ₂O₃ (Lanthanum

oxide), Ce₂O₃ (Cerium oxide), Yb₂O₃ (Ytterbium oxide), and Y₂O₃ (Yttrium oxide) as reported in the

technical report filed under Terra’s profile on sedarplus.ca on February 9 th, 2023 . Skyharbour

optioned the Project to Terra, and under the Option Agreement, assuming the 75% interest is earned,

Terra will fund exploration expenditures totaling CAD $10,500,000, as well as pay Skyharbour CAD

$11,100,000 in cash, of which $6,500,000 can be settled for shares in the capital of Terra over the

earn-in period.

These light rare earths are key elements in automotive, batteries, magnets as well as other

industries. Lanthanum has two main uses: as a phosphate binder in medicine to treat high blood

phosphate levels in kidney disease patients, and in various industrial applications like manufacturing

nickel-metal hydride batteries, catalytic converters, specialty glass, and as a component in alloys for

lighters and other products.

Cerium is used in a variety of applications, including as a polishing agent for glass and a catalyst in

automotive catalytic converters to reduce emissions. It is also used in metallurgy to improve alloys

and steel, and in the production of flints for lighters, incandescent gas mantles, and components for

batteries.

Ytterbium is used in a variety of applications including improving stainless steel, dental alloys,

portable x -ray machines, atomic clocks, superconductors, lasers and amplifiers, fiber optic

communications, and quantum computing.

Yttrium is used in a variety of applications, most notably as a key component in phosphors for LEDs

and displays, and in lasers for medical and industrial uses. It is also used in ceramics, such as those

for high-temperature fuel cells and medical implants , as a metallurgical additive for alloys, and in

electronics like microwave filters and automotive sensors. Additionally, specific yttrium isotopes have

medical applications in cancer therapy and diagnostic imaging.

Below is a link from the Natural Resources Canada (NRC) website showing the Falcon Point Project

in Saskatchewan which hosts the Fraser Lakes B Deposit. The South Falcon East Project is a portion

of this former project. Through an NRC grant to the University of Saskatchewan in March 2024, The

Government of Canada has contributed to a multiyear study of REE’s in northeastern Saskatchewan.

The Fraser Lakes B Deposit is part of this study and Terra is a participating partner. REE’s continue

to be identified in recent drilling programs.

“With renewed interest in rare earth elements it is important that shareholders understand we are

sitting on an active REE deposit,” said Greg Cameron, CEO of Terra. “This deposit adds significant

upside, particularly in light of the recent environment which places far more value on the strategic

importance of rare earth elements. Management is committed to making sure this value is

understood and unlocked as we continue with the ongoing advancement Fraser Lakes,” continued

Mr. Cameron.

“We are excited to be involved in the expansion of Rare Earth Element deposit understanding and

inventory in Canada”, commented Trevor Perkins, Vice President of Exploration for Terra. “With the

current emphasis on REE, it is time to highlight this aspect of our Fraser Lakes B Uranium and REE

Deposit. We are sure that with continued drilling and study of the Fraser Lakes B deposit we will add

to both the uranium and REE resource,” continued Mr. Perkins.

South Falcon East Project Summary:

The South Falcon East Project is a uranium exploration project in the southeast Athabasca Basin

and represents a portion of Skyharbour ’s former Falcon Point Project. The project covers

approximately 12,464 hectares and is located 18 kilometres outside the Athabasca Basin, roughly

50 kilometres east of the Key Lake mill.

The project hosts the Fraser Lakes B Uranium-Thorium Deposit, which contains a historical inferred

resource of 6.9 million pounds U ₃O₈ at an average grade of 0.03% U ₃O₈ and 5.3 million pounds

ThO₂ at 0.023% ThO₂. Mineralization is hosted in shallow, structurally disrupted metasedimentary

rocks and pegmatites, displaying Athabasca-style basement-hosted characteristics and occurring in

association with well-defined EM conductors.

Qualified Person:

The technical information in this news release has been prepared in accordance with the Canadian

regulatory requirements set out in National Instrument 43-101 and reviewed and approved by Serdar

Donmez, P.Geo., VP of Exploration for Skyharbour, as well as a Qualified Person.

About Terra Clean Energy Corp.:

Terra Clean Energy (formerly Tisdale Clean Energy Corp) is a Canadian-based uranium exploration

and development company. The Company is currently developing the South Falcon East uranium

project, which hosts an inferred uranium resource within the Fraser Lakes B uranium/thorium deposit,

located in the Athabasca Basin region, Saskatchewan, Canada.

About Skyharbour Resources Ltd.:

Skyharbour holds an extensive portfolio of uranium exploration projects in Canada's Athabasca

Basin and is well positioned to benefit from improving uranium market fundamentals with interest in

thirty-seven projects covering over 616,000 hectares (over 1.5 million acres) of land. Skyharbour has

acquired from Denison Mines, a large strategic shareholder of the Company, a 100% interest in the

Moore Uranium Project, which is located 15 kilometres east of Denison's Wheeler River project and

39 kilometres south of Cameco's McArthur River uranium mine. Moore is an advanced -stage

uranium exploration property with high -grade uranium mineralization in several zones at the

Maverick Corridor. Adjacent to the Moore Project is the Russell Lake Uranium Project, in which

Skyharbour is operator with joint -venture partner RTEC. The project hosts widespread uranium

mineralization in drill intercepts over a large property area with exploration upside potential. The

Company is actively advancing these projects through exploration and drilling programs.

Skyharbour also has joint ventures with industry leader Orano Canada Inc., Azincourt Energy, and

Thunderbird Resources at the Preston, East Preston, and Hook Lake Projects, respectively. The

Company also has several active earn-in option partners, including CSE-listed Basin Uranium Corp.

at the Mann Lake Uranium Project; TSX-V listed North Shore Uranium at the Falcon Project; UraEx

Resources at the South Dufferin and Bolt Projects; Hatchet Uranium at the Highway Project; CSE -

listed Mustang Energy at the 914W Project; and TSX-V listed Terra Clean Energy at the South Falcon

East Project.

In aggregate, Skyharbour has now signed earn-in option agreements with partners that total to over

$36 million in partner-funded exploration expenditures, over $20 million worth of shares being issued,

and $14 million in cash payments coming into Skyharbour, assuming that these partner companies

complete their entire earn-ins at the respective projects.

Skyharbour's goal is to maximize shareholder value through new mineral discoveries, committed

long-term partnerships, and the advancement of exploration projects in geopolitically favourable

jurisdictions.
