Where the shafts, the ore, and the town actually sit
Coordinates pulled from Ontario's mineral inventory records and Evolution Mining's NI 43-101 technical report, cross-checked against the report's own operations map.
Fig. 1 — Operations plan map, prepared by Goldcorp (2018), reproduced from the Red Lake Operations NI 43-101 Technical Report, p. 4-3. Yellow stars mark each named complex; the magenta outline is the Goldcorp/Premier Gold joint-venture boundary. Grid lines are UTM NAD83 Zone 15, spaced 2,000 m apart at the scale bar.

| 4Reid ShaftCampbell Complex | — not published to the arc-second | ≈150 m westof the Campbell Shaft | Sunk to 1,819 m. Both Cochenour and Campbell ore are hoisted here, not at Cochenour itself. |

The 180-page NI 43-101 technical report — full-text searched end to end — contains no mention of a crown pillar, subsidence, ground heave, or backfilling under the townsite. Its only uses of "pillar" refer to unrelated sill-pillar stope recovery at Campbell.
So the historic crown-pillar collapse-and-backfill (12 m thick, "under and around the town of Cochenour," per a 2005 Canadian Mining Journal piece) isn't corroborated by this primary document, and neither it, the Ontario mineral inventory record, nor the Red Lake Regional Heritage Centre's history page name a specific street or footprint for where under the town it sat. That detail would likely need the original 1997–2003 Goldcorp compilation reports, a provincial abandoned-mine hazard file specific to Cochenour, or a local newspaper archive — none of which surfaced in this pass.
