Sudbury Basin SE Rim · NTS 41I/10 SW · ~1.5 mi SE of Falconbridge Mine
Overview
Manchester Offset Dyke — Falconbridge doorstep · Cu-Ni-PGE-Au offset-dyke target. Historical assays to 2.02% Cu, 1.90% Ni, 2.85 g/t Au, 1 g/t Pt+Pd.
322.5 ha block on the SE rim of the Sudbury Basin — ~1.5 mi SE of the Falconbridge Nickel Mine (571,573 t Ni + 293,042 t Cu) with documented historical assays to 1.90% Ni, 2.02% Cu, 2.85 g/t Au and 1 g/t Pt+Pd along an inferred offset-dyke trend.
Summary
Within the Sudbury Basin SE Rim. Commercial structure (option, JV, earn-in, royalty, work commitment) is open and negotiable; a full data room is available on request.
Property Setting
A 322.5 ha, 15-cell block on the SE rim of the Sudbury Basin in Falconbridge / Dryden Township — the type Cu-Ni-PGE-Au producing camp. The block sits ~1.5 miles SE of the Falconbridge Nickel Mine (571,573 t Ni + 293,042 t Cu from 41.95 Mt milled to 1966).
Anchored by the 1969 Pershland / Bayne assessment file (41I10SW0040) — A.S. Bayne, P.Eng. — documenting a Sudbury gabbro / quartz diorite synclinal complex with NE-trending faults, breccias, and a Frood-style offset-dyke analogue. Validated assay highlights from the report callouts include up to 1.90% Ni, 2.02% Cu, 2.85 g/t Au and 1 g/t Pt+Pd — historical, indicative only. A second anchor (Dryden North / L.G. Frank) sits along the inferred Manchester Offset Dyke trend. Compilation completed to NI 43-101 standards; modern field verification is the next step — this is a verification-first opportunity, not a drill-ready property.
