Short answer: there is a current regional map and directory for rockhounding experiences, but I did not find one official GPS download that proves every listed location is currently legal, public and open for collecting.[1][2][unverified]

Best current starting points

Hastings County’s Recreational Geology page has an “Explore Map” link and a current directory of rockhounding experiences, including Lakeside Gems field trips, Princess Sodalite Mine, the CN Rock Pile, and other geology-related attractions.[2]

For a no-fee lead, Destination Ontario describes the CN Rock Pile as being along the Hastings Heritage Trail, across from the Bancroft Municipal Office, and says rockhounding there is free.[3] Treat that as a current tourism description rather than a complete legal/access guarantee: confirm the site’s condition, posted rules, hours and collecting permissions before removing anything.[unverified]

Destination Ontario also identifies Princess Sodalite Mine as a rock-farm experience and Lakeside Gems as a source of tools and geologist-led collecting trips.[3] Those are operator-led or commercial options, so use the linked operator information for current directions, fees, schedules and access conditions rather than relying on an old coordinate list.[unverified]

BancroftOntario.com’s mineral-collecting page is useful background and names area sites and tours, but it is a compiled guide—not a government land-tenure or legal-access registry.[4][unverified]

How to check a coordinate before collecting

The Central Canadian Federation of Mineral Societies warns that road logs and mileages in older guides may have changed, GPS coordinates may be outdated, private-property ownership may have changed, and landowner permission may be required. It also notes that some Crown land can be off-limits.[5]

Ontario’s Hobby Mineral Collecting Policy says the collector is responsible for confirming whether land is open and directs collectors to the Ministry of Mines’ MLAS Map Viewer and the local Land Registry Office through ONLand.[7] The MLAS page confirms that non-registered users can use its map viewer to see active unpatented mining claims.[6]

• Use the Hastings County page and its linked operator pages to identify the current attraction or experience first.[2]
• For the CN Rock Pile, verify the current trail/site conditions and any posted collecting rules before travelling.[2][3][unverified]
• For Princess Sodalite, Lakeside Gems or another fee-based site, confirm access directly with the operator.[2][3][unverified]
• For a historic guide, blog or forum coordinate, treat it only as a lead; check current surface and mining rights and obtain any required permission.[5][7]
• Do not enter a site merely because a GPS pin lands beside a road, trail, pit or exposed rock.[unverified]

What I would not publish as “the legal map”

I would not reproduce exact coordinates from an old guide, forum post or unverified blog as a definitive public collecting list. Coordinates can remain geographically accurate while access, ownership, claims, protected-area status or collecting rules have changed.[5][unverified]

Bottom line: start with Hastings County’s current recreational-geology directory/map, use Destination Ontario’s CN Rock Pile listing as a documented free-rockhounding lead, and use the operator links for fee-based experiences.[2][3] No single current authoritative GPS list was verified, so every natural or historic site still needs a site-specific access and land-status check.[unverified]
