SKYHARBOUR PARTNER COMPANY TERRA CLEAN ENERGY ANNOUNCES IMMEDIATE FOLLOW-UP SUMMER DRILL PROGRAM ON THE BACK OF DRILL RESULTS FROM WINTER PROGRAM AT SOUTH FALCON EAST URANIUM PROJECT

Skyharbour Resources Ltd.'s partner company Terra Clean Energy Corp. has released results from its winter 2025 drill program and has provided an update on the coming summer drill program at the South Falcon East uranium project, which hosts the Fraser Lakes B uranium deposit. The property lies 18 kilometres outside of the edge of the Athabasca basin, approximately 50 km east of the Key Lake mill and former mine. Skyharbour optioned the project to Terra, and, under the option agreement, assuming the 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.

Winter 2025 assay results

Terra conducted a helicopter-supported drill program at the South Falcon East property earlier in the year. Seven diamond drill holes were completed at the Fraser Lakes B uranium deposit for a total of 1,927 metres. The initial results of these drill holes were reported in press releases dated March 10, 2025, and April 1, 2025. During the winter drill program, 682 samples were submitted for geochemical analysis at the geoanalytical laboratory at the Saskatchewan Research Council in Saskatoon, Sask. Results have been received and compiled.

Results highlight several wide zones of uranium mineralization in holes SF0063, SF0065, SF0066 and SF0067, which were drilled to test an inferred northwest-southeast-trending fault cutting through the Fraser Lakes B uranium deposit. The easternmost hole, SF0065, returned 18.1 metres at 0.03 per cent triuranium octoxide, including a subinterval of 0.12 per cent U3O8 over 1.6 metres. Another interval within this hole returned 0.13 per cent U3O8 over 0.51 metre within a 3.72-metre interval that ran 0.09 per cent U3O8. The northernmost hole, SF0067, returned 3.87 metres at 0.05 per cent U3O8, including a subinterval of 0.17 per cent U3O8 over 0.5 metre. This 0.5-metre interval represents the best sample of the program. Another interval within this hole returned 0.03 per cent U3O8 over 8.05 metres, with 0.16 per cent U3O8 over a 0.5-metre interval within. The best intersections of the program, which are some of the better intersections for both grade and width within the deposit, remain open to the north and to the east.

When compared with previously released equivalent uranium (per cent U3O8 equivalent) results from the downhole gamma logging, the lab results typically highlight wider intervals of mineralization with higher grades than those identified by the probe. It is not unexpected or unusual for the lab results to be higher than the equivalent gamma results. The variation can be on average, 5 per cent to 30 per cent higher.

The typical pathfinder elements used to vector toward uranium in the basin, including cobalt, nickel, copper, lead and zinc, all appear elevated within the metasedimentary package hosting the mineralized pegmatites, particularly Co and Ni. Elevated Pb is closely associated with elevated uranium. Hole SF0067 contains some of the higher pathfinder values, indicating another vector toward the north.

"The results from the winter drilling program are very encouraging," commented Trevor Perkins, vice-president of exploration for Terra. "The thick mineralized intersections within the pegmatites and graphitic sediment package are a good sign. The fact that the grades are improving to the north along the NW fault shows that we are moving in the right direction for a higher-grade discovery," continued Mr. Perkins.

"These are some of the best drill results to date at South Falcon," said Greg Cameron, chief executive officer of Terra. "The drills returned multiple hits, and an 18-metre run of uranium at the established grade of the deposit is a significant and positive development. Several holes returned higher-grade values, including as much as 466 per cent greater than the deposit average. These results indicate our plan to increase the size and grade of the deposit is both sound and compelling. Drilling will continue almost immediately, and we're excited to see what the next phase reveals," continued Mr. Cameron.

Coming summer 2025 drill program

Terra is planning an extensive follow-up drill program this summer, consisting of approximately 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 places 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, you require 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 been identified in the Fraser Lakes B deposit area. The location 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 mineralization and additional mineralized pegmatites.

The coming program will be a helicopter-supported drill program comprising 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 soon, and the campaign will be executed by TerraLogic Exploration Inc. under the supervision of Mr. Perkins. Operations will be based out of a local contracting camp with helicopter support for the daily drilling activities. The expected budget for this program is anticipated to be $2-million.

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

South Falcon East project summary

The South Falcon East project is a uranium exploration project in the southeastern Athabasca basin and represents a portion of Skyharbour Resources' former South Falcon project. The project covers approximately 12,464 hectares and is located 18 kilometres outside of 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 at an average grade of 0.03 per cent U3O8 and 5.3 million pounds ThO2 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 electromagnetic conductors.
