About this spot

Site of Ontario's first gold rush: Marcus Powell hit visible gold on the Richardson farm near Madoc in 1866, and the hamlet of Eldorado boomed to 80 hotels almost overnight. The mine itself produced only ~100 oz before closing in 1869 — a classic cautionary tale. Provincial plaque on site.

Before you go

Historic context point only — the old workings are on private land and there is no public panning here. View the Ontario Heritage Trust plaque from the roadside. Verify current status before visiting the area.
