03The targets

Three targets, three independent stories.

Each target has its own geological merit, historical evidence, and a defined Phase 2 drill allocation.

04The geology

Two deposit models, one property.

Porter Lake hosts both classic Athabasca fault‑hosted targets and large‑scale Rossing‑type granitoid targets.

A
Rossing‑type granitoid

Large scale, low‑to‑medium grade.

Uranium hosted in large granitic formations. Global Rossing‑type deposits typically grade 0.04–0.07% U₃O₈. Porter Creek surface samples already grade up to 0.58% U₃O₈ — an order of magnitude above the global Rossing range — across a 2.9 km exposed granitoid corridor.

B
Fault‑hosted (Athabasca)

The classic high‑grade discovery model.

Concentrated uranium along shear zones, faults and electromagnetic conductors. Historical EM conductors run through Blackstone and Dragon. 1950s drilling at Blackstone hit 0.20% U₃O₈ over 1 ft but missed the main conductor. RAMP‑HD 2025 mapped uranium directly along that conductor.
