Premier American Uranium Inc. (TSXV: PUR) (OTCQB: PAUIF) has reported mid-season results from its 2026 exploration drilling program at the wholly-owned Kaycee Project in Wyoming's Powder River Basin. Drilling at the West Diane target has intersected uranium mineralisation in six of eight holes, highlighted by 10 ft grading 0.064% eU₃O₈ in drillhole WD26-012 — the thickest mineralised interval reported from the 2026 program to date. The company also expanded its Kaycee land package to 31,724 acres after securing an additional 1,883 acres of mineral rights near the Rustler target, connecting the Rustler and Stampede claim blocks. Investors may be watching progress as approximately 66% of the planned 100,000-ft drill program has now been completed.

Key Points

  • Premier American Uranium Inc. (TSXV: PUR / OTCQB: PAUIF)
  • West Diane target delivers 10 ft of 0.064% eU₃O₈ in drillhole WD26-012, with uranium mineralisation in six of eight holes
  • 80 drillholes totalling 65,620 ft completed as of September 25, 2026; land package now 31,724 acres after 1,883-acre expansion
  • Investors will be watching results from the resumption of Rustler drilling across the expanded target area after the West Diane campaign concludes

West Diane Target Delivers Strongest Intercept of 2026 Kaycee Program

Initial drilling at the West Diane target has returned uranium mineralisation in six of eight holes, totalling 7,360 ft. The standout result is drillhole WD26-012, which intercepted 10 ft of 0.064% eU₃O₈, including 5.5 ft of 0.076% and 2 ft of 0.092% eU₃O₈. The release states that current drilling is focused on the upper sandstone unit within the Fort Union Formation — one of two historically productive host formations in the Smith Ranch-Highland area of the Powder River Basin — with the objective of better defining the trend and extent of a partially delineated paleochannel identified through historical drilling.

Rustler Target Expanded After Encouraging Drill Results

At the Rustler target, six of 22 newly reported drillholes intersected uranium mineralisation grading at least 0.02% eU₃O₈, including 2.5 ft grading 0.063% eU₃O₈ in RT26-121 and 3.5 ft grading 0.037% eU₃O₈ in RT26-116. Drilling at Rustler was paused after 45 holes while the company secured 1,883 additional acres of mineral rights immediately north and west of the existing claim block. Two mineralised sandstone host units have been identified within the lower Wasatch Formation, with gamma results indicating possible stacked roll fronts in the upper unit, according to the disclosure.

Overall 2026 Program Progress and Kaycee Project Scale

As of September 25, 2026, PUR had completed 80 conventional mud-rotary drillholes for a cumulative 65,620 ft — representing approximately 66% of the planned 100,000-ft program. The Kaycee Project spans over 42 square miles across a 36-mile mineralised trend hosting more than 110 miles of identified roll fronts. The release states the project is believed to be the only one in the Powder River Basin where all three historically productive sandstone formations — Wasatch, Fort Union, and Lance — are mineralised and potentially accessible for in-situ recovery extraction.
