East Valley Pediment
A covered porphyry target beneath 30–80 m of glacial till. A magnetic high coincident with a 700 m × 400 m gravity anomaly is the most likely host of a buried, intact intrusive centre — the kind of body the eroded Sundance Ridge surface workings represent at depth.
The hypothesis
The eastern Copper Mountain trend has produced more than three billion pounds of copper since 1923, all from intrusions of the same Late Triassic alkalic suite. East Valley sits 800 m east of Sundance Ridge under cover.
The combination of a coincident magnetic high and a 1.4 mGal gravity high is consistent with an unweathered, sulfide-bearing intrusive at depth. None of CIM’s three historic predecessors drilled it — the cover thickness made target definition uncertain until the 2025 IP-MT survey resolved it.
Phase II programme
Nine HQ-diameter diamond drill holes test the centre of the geophysical anomaly with two fences of three holes plus three step-out holes. Total metres: ~7,200. Mob June 2026.
