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.

This guide is general information for recreational prospectors — it is not legal advice. Mining, land-access, and environmental regulations change and vary site by site. Always verify the current rules with the official sources linked above before heading out, obtain permission from private landowners and mineral-claim holders, and respect First Nations rights, settlement lands, and treaty areas — some lands require permission or are closed to panning entirely.

Washout risk. Recent or incoming rain (or a rising gauge) can put bars under water fast — consider waiting for two or three dry days before heading out.
Washout risk and the panning window are heuristics — rainfall against gauge trend — not a safety assessment. Check advisories and the forecast before entering any river.
Getting there
Nearest town:Madoc, Ontario — about 8.0 km N of it in a straight line. That is not driving distance: in gold country a 40 km straight line is regularly a two-hour drive on gravel.

The last mile
Both map apps route to the coordinate, not to a legal access point. The final stretch to a river is routinely an unmaintained forest service road, a locked gate, private frontage or a bank you cannot get down. Check the road status before you leave, tell someone your plan, carry a paper backup — cell coverage in these valleys is patchy — and turn around rather than trespass. Water crossings and washouts are normal after rain.
