Baselode Energy Reports First Unconformity-Style Uranium Mineralisation in Northeast Thelon Basin

• First unconformity-style uranium mineralisation identified in northeast Thelon Basin sandstone at Loki target
• 600-metre alteration zone discovered, described as most extensive observed in Thelon Basin to date
• Aberdeen Project spans 95,519 hectares in Nunavut with existing Tatiggaq and Qavvik uranium discoveries
• Company holds total 485,519 hectares across Thelon and Athabasca Basins with multiple prospects
• 2025 drilling programme continues at Bjorn, Tarzan and Lobster targets with results pending

Baselode Energy Corp. (TSXV: FIND; OTCQB: BSENF) is a Canadian uranium exploration company that holds approximately 390,000 hectares in the Athabasca Basin area of northern Saskatchewan and 95,519 hectares in Nunavut's Thelon Basin. The company's exploration strategy focuses on discovering near-surface, high-grade uranium deposits in these two basin areas.

The Aberdeen Project in Nunavut hosts the Tatiggaq and Qavvik uranium discoveries. Tatiggaq comprises multiple mineralised lenses over 300 metres of strike length at depths between 80 and 180 metres, with intercepts including 2.25% U₃O₈ over 11.1 metres. In the Athabasca Basin, the company discovered the ACKIO uranium prospect, which measures greater than 375 metres along strike and 150 metres wide, with mineralisation starting at 28 metres depth.

Unconformity-Style Uranium Discovery

Elevated radioactivity has been identified in sandstone just above the unconformity at the Loki target on the Aberdeen project. According to CEO Rebecca Hunter, this represents

"the first instance of sandstone-hosted, unconformity-style uranium mineralisation in the northeast Thelon Basin."

The discovery confirms the presence of unconformity uranium mineralisation in this region of the basin.

The Loki target is located within an almost 4-kilometre gravity low trend that hosts a Thelon sandstone outlier less than 150 metres thick. Hunter stated that the results "confirm the presence of unconformity uranium mineralisation in the northeast Thelon Basin." The radioactivity occurs within the sandstone formation above the geological unconformity contact.

Baselode identified the target through geophysical methods, specifically gravity surveying that outlined the structural trend. The company's exploration approach combines geophysical targeting with geological mapping to identify areas of interest. The Loki discovery adds to the company's existing uranium prospects across its land holdings in the region.

Alteration Zone and Geological System

The company has intersected what it describes as "a broad and intense alteration zone spanning 600 metres to date" at the Loki target. Hunter noted that "the alteration within the sandstone column is the most extensive observed in the Thelon Basin to date." This alteration zone indicates hydrothermal activity in the geological system.

According to Hunter, the results "demonstrate a large unconformity hydrothermal system was active in the area." The CEO explained that "the Loki sandstone outlier and structural disruption within the Thelon sandstone point to substantial post-Basin fault movement."

The geological observations include structural features within the sandstone formation and evidence of hydrothermal fluid movement. The alteration zone extends over a 600-metre span based on current drilling results. The company has not yet completed testing of the full extent of the alteration system at the Loki target.

Project Portfolio and Exploration Programme

Baselode's Aberdeen Project hosts over 50 exploration targets, many exhibiting alteration and geochemical anomalies from historical drilling or remaining untested. The Tatiggaq discovery includes multiple mineralised lenses across 300 metres of strike length, with only 500 metres of a 1,500-metre anomaly drill tested. The Qavvik discovery covers a 100 by 100 metre area extending from surface to 400 metres depth.

The company's ACKIO prospect in the Athabasca Basin comprises at least 9 separate uranium pods with mineralisation from 28 metres to approximately 300 metres depth. The bulk of mineralisation occurs in the upper 120 metres, and ACKIO remains open at depth and in multiple directions. These discoveries provide the foundation for the company's current exploration activities.

Baselode's 2025 programme includes drilling at multiple targets. Hunter stated that "our drilling progress on Bjorn, Tarzan and Lobster will be released as we process the results." The programme aims to test additional prospects across the company's land holdings. The company has not specified timelines for releasing results from these ongoing drilling activities.

Next Steps and Programme Outlook

The company continues drilling activities at Bjorn, Tarzan and Lobster targets, with results to be released upon completion of data processing. The 2025 programme focuses on testing multiple prospects across the company's portfolio. Additional work at the Loki target may include further drilling to define the extent of mineralisation and alteration.

Baselode maintains exploration activities across both the Thelon and Athabasca Basin holdings. The company's approach involves systematic testing of geophysical and geochemical targets identified through regional surveys and historical data review.
