Terra Clean Energy Corp. (CSE: TCEC) announced on October 29, 2026 that it has completed construction of three drill pads and excavated five trenches at its Marysvale Uranium Mines Project in Utah, marking a significant operational milestone ahead of a planned late-November drilling campaign. Drilling mobilisation has been revised from early November to late November due to equipment availability. The company states that trenching results are being integrated with historical mine records and a 3D geological model to finalise drill-hole locations, a development investors in junior uranium exploration companies will be watching closely.

Key Points

  • Terra Clean Energy Corp. (CSE: TCEC, OTCQB: TCEFF, FSE: C9O0) is a Canadian-based uranium exploration and development company.
  • Drill pads 2, 3, and 5 are complete, and five trenches have been excavated and geologically logged at the Marysvale Uranium Mines Project in Utah.
  • Drilling mobilisation is now expected in late November 2026; KB Drilling Co. Inc. has been contracted for the core drilling program.
  • Investors may watch for further target assessment updates and drill results as the November program gets underway.

Drill Pad Construction and Trenching Results at Marysvale

The company reports that construction of drill pads 2, 3, and 5 is complete, while trenches 1, 2, 3, 4, and 6 have been excavated and geologically logged. The release states that trenching has exposed numerous structures and faults, improving the geological team's understanding of the project's structural framework. These observations are being assessed alongside historical mine records and the company's 3D geological model to finalise drill-hole locations, evaluate targets, and prioritise drilling at the Marysvale, Utah site.

Targets Identified Across Three Drill Pads

Each completed pad is assigned specific targets. Pad 2 will test the 706 Vein, where historical assays recorded high-grade uranium, and an extension of the Prospector 1 Vein at depth. Pad 3 targets the eastern side of the property near the Auberg Shaft, where historical mineralisation was identified, and tests for an eastern extension of the Prospector 1 Vein. Pad 5 will test the Prospector 3 Vein at the 300-foot level and assess whether mineralisation continues at depth, referencing a historical drill hole from the 1970s and a 1973 Callahan report suggesting the Prospector 1 Vein remains open to at least 1,400 feet. The company notes historical reports do not establish present-day grade or economic potential.

Marketing Services Agreement Disclosed Alongside Drilling Update

Alongside the drilling announcement, Terra Clean Energy disclosed it has entered into a marketing services agreement with 1001600878 Ontario Inc., effective October 31, 2026.
