PCE

Patterson Corridor East (PCE)

The uranium occurrence is situated only 3.5 km east of the world-class Tier 1 Arrow Deposit and shares several geological characteristics very analogous to Arrow. Initial results at PCE have indicated an expansive footprint with remarkable continuity of mineralization. Further, the observations of the drill core indicate a large, pervasive hydrothermal system.

The system is open in all directions, with mineralization spanning over 600 m in strike length and 600 m vertical extent. As of spring 2025, mineralization has been intersected in 35 of 64 holes including 27 holes with occurrences >10,000 cps, of which 13 have encountered >61,000 cps (off-scale).

Drillhole RK-25-232 at PCE marks NexGen’s best discovery-phase assay intercept, with 15.0 m at 15.9% U3O8, including a peak intercept of 0.5 m at 68.8% U3O8.

Geological Characteristics

  • Hydrothermal alteration system analogous to Arrow
  • Semi-massive to massive veins, fracture coatings, and disseminations (peak intercept of 0.5 m at 68.8% U3O8) hosted exclusively within crystalline basement rocks
  • Well-developed hydrothermal fluid system – hematite, limonite, clay, and chlorite alteration
  • Formation conditions linked to significant orebodies within the Athabasca Basin

2025 Exploration Program comprising a 43,000 m drill program focused on unlocking the potential.

  • Drillhole RK-25-232 at PCE marks NexGen’s best discovery-phase assay intercept, with 15.0 m at 15.9% U3O8, including a peak intercept of 0.5m at 68.8% U3O8
  • High-grade subdomain doubles in size to 210 m strike and 335 m vertical extent

Mineralization confirmed across 600 m of strike length and 600 m vertical extent within an overall hydrothermal system covering 1.4 km by 1.2 km.
