Authorization

Where collection is allowed

The Sterling Hill Mining Museum explicitly offers rock collecting on the Mine Run Dump during current collecting hours.

Confirm current hours, weather availability, age requirement, price, pound charge, and whether the tour and collecting require separate tickets.

Rules

Tools, limits, and timing

Tools and methods

Bring only currently approved tools and mandatory eye protection. The museum recommends the Mine Run Dump for adult collectors and directs children toward sluicing.

Amount and use

Pay the current admission and per-pound charge; remain in the assigned collecting area. Event access does not authorize entry to closed mine or pit areas.

Season and current status

Collecting is weather permitting; check the museum’s current daily schedule.

Conditions

Rules to confirm at the site

  • Check in before collecting.
  • Meet the current age rule.
  • Wear eye protection.
  • Have material weighed and paid for.

An old webpage, saved map, app layer, social post, or prior visit cannot override a current closure, posted boundary, permit condition, mining claim, staff instruction, or landowner decision.

Geology

What makes the site geologically useful

The Franklin–Sterling Hill district contains an exceptionally diverse zinc-ore mineral assemblage, including many minerals that fluoresce under ultraviolet light.

Fluorescence is a property, not a complete identification; visible color, hardness, streak, and host association still matter.
