# Sterling Hill Mine Run Dump: legal collecting field guide Canonical page: https://lithomap.app/resources/field-trips/sterling-hill-mineral-collecting-new-jersey Last access and rule review: September 18, 2026 Page purpose: Original LithoMap trip-planning reference for an explicitly authorized rock, mineral, or non-dinosaur fossil collecting destination. ## Direct answer A museum-operated collecting dump at a world-famous zinc deposit, with separate age, access, fee, and safety rules from the underground tour. ## Location and material - State: New Jersey - Area: Sterling Hill Mining Museum, Ogdensburg - Category: Mineral collecting - Collection status: Program or paid access - Expected material: Fluorescent minerals, Zinc ore minerals, Franklinite and calcite assemblages ## Authorization The Sterling Hill Mining Museum explicitly offers rock collecting on the Mine Run Dump during current collecting hours. ## Access Confirm current hours, weather availability, age requirement, price, pound charge, and whether the tour and collecting require separate tickets. ## Tools, limits, and season - Tools: Bring only currently approved tools and mandatory eye protection. The museum recommends the Mine Run Dump for adult collectors and directs children toward sluicing. - Limits: 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 - Check in before collecting. - Meet the current age rule. - Wear eye protection. - Have material weighed and paid for. ## Geology 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. ## Field plan 1. Open the current official source and check alerts before leaving home. 2. Confirm the property boundary, parking location, and activity rules on arrival. 3. Begin with observation or surface searching and make the smallest possible disturbance. 4. Photograph context before handling any material that the current rules allow you to keep. 5. Pack out every item you brought and leave protected or uncertain material in place. ## Safety - Follow museum boundaries around all workings. - Use UV lamps without shining them into eyes. - Minimize dust and wash hands after handling ore. ## Official sources - Current collecting and visitor information — Sterling Hill Mining Museum: https://www.sterlinghillminingmuseum.org/ This guide is not a permit, reservation, boundary survey, legal opinion, guarantee of access, or promise of a find.
