SKYHARBOUR PARTNER COMPANY TERRA CLEAN ENERGY ANNOUNCES AN UPCOMING DRILL PROGRAM AT THE SOUTH FALCON EAST URANIUM PROJECT

Skyharbour Resources Ltd.'s partner company, Terra Clean Energy Corp., is preparing to commence a targeted drill program on the Fraser Lakes B uranium deposit following up on the very encouraging results reported in the winter 2025 program. Skyharbour optioned the project to Terra and under the option agreement, assuming the full 75-per-cent interest is earned, Terra will finance exploration expenditures totalling $10.5-million, as well as pay Skyharbour $11.1-million in cash, of which $6.5-million can be settled for shares in the capital of Terra over the earn-in period.

Upcoming summer 2026 drill program

Terra is planning an extensive follow-up drill program for late summer of 2026, consisting of up to 2,500 metres of drilling. The purpose is to test an area highlighted in the winter 2025 program where it is interpreted that a north-northwest-trending brittle structure, a north-dipping structure with strong clay alteration and mineralized pegmatites with hydrothermal hematite alteration hosted in graphitic pelitic gneiss all intersect. This puts many of the indicators identified as being key components for higher-grade uranium mineralization all in the same location.

It is generally accepted that for higher-grade uranium deposits in the Athabasca basin there are several key indicators: graphitic metasediments, brittle reactivated basement structures, reducing fluid (indicated by clay alteration) and oxidizing fluid (indicated by hematite alteration, transports uranium). All these features have now been identified in the Fraser Lakes B summer target area. Where they are projected to intercept is considered a top-priority target area for the discovery of a higher-grade, unconformity-related basement hosted uranium deposit and additional mineralized pegmatites.

The upcoming program will be a helicopter supported drill program encompassing seven to 10 diamond drill holes targeting an area approximately 120 to 150 metres north of drill holes SF0063, SF0065, SF0066 and SF0067, which were completed during the winter program. The summer field program is anticipated to commence mid to late August. The campaign will be executed by Terralogic Exploration Inc. under the supervision of their staff and C. Trevor Perkins, vice-president, exploration, for Terra. Operations will be based out of a local contracting camp with helicopter support for the daily drilling operations. The expected budget for this program is anticipated to be $1.75-million.

"We are excited to get back in there and test where the clay alteration intersects the mineralized zone and graphitic sediment package," commented Trevor Perkins, vice-president, exploration, Terra Clean Energy. "This is an exciting target as it can bring together many of the key features associated with the known basement hosted unconformity deposits in and around the Athabasca basin."

Terms of the option agreement:

Under a revised agreement, the outstanding requirements for Terra to earn a 51-per-cent interest in South Falcon East are as follows:

On execution of the amendment: (a) issuing Skyharbour Resources 2.65 million common shares; and (b) making a $100,000 cash payment to Skyharbour;

1. On or before July 31, 2027, incurring an additional $1.4-million in work expenditures on South Falcon East (with $75,000 of such work expenditures to have been incurred on or prior to Oct. 1, 2026).
2. On or before July 31, 2028: (a) incurring an additional $1-million in work expenditures on South Falcon East; (b) issuing Skyharbour $1.77-million in common shares based on the VWAP (volume-weighted average price) calculated on the day of issuance; and (c) making a $1.7-million cash payment to Skyharbour.

Upon having earned a 51-per-cent interest in South Falcon East, Terra will have the option to earn an additional 24-per-cent interest in South Falcon East (bringing its interest to 75 per cent) by:

1. On or before Jan. 1, 2029, incurring an additional $2.5-million in work expenditures on South Falcon East;
2. On or before Jan. 1, 2030: (a) incurring an additional $3.5-million in work expenditures on South Falcon East; (b) issuing Skyharbour $4.5-million in common shares based on the VWAP calculated on the day of issuance; and (c) make a $2-million cash payment to Skyharbour.

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 U3O8 (triuranium octoxide) at an average grade of 0.03 per cent U3O8 and 5.3 million pounds ThO2 (thorium dioxide) at 0.023 per cent 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.

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 43 projects covering over 662,887 hectares (1,638,029 acres) of land. Skyharbour owns a 100-per-cent 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 at the Maverick zone highlighted by drill results of up to 6.0 per cent U3O8 over 5.9 metres, including 20.8 per cent U3O8 over 1.5 metres at a vertical depth of 265 metres. Adjacent to Moore, Skyharbour is advancing several uranium properties within the broader Russell Lake project area with its joint venture partner and large strategic shareholder Denison Mines. Collectively these co-flagship projects host multiple zones of high-grade uranium mineralization across a highly prospective land package with significant exploration upside, and the company is actively working these assets through exploration and drilling programs.

Skyharbour now has joint ventures with industry-leaders Denison Mines and Orano Canada Inc. at the Russell Lake properties and the Preston project, respectively. The company also has several active earn-in option partners, including Canadian Securities Exchange-listed Nexus 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 914-watt 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 potentially over $76-million in partner-financed exploration expenditures, and over $42-million in cash and share payments coming into Skyharbour, assuming that these partner companies complete the earn-ins at their 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.

We seek Safe Harbor.
