The Mine Run Dump

Our mine run dump area is perfect for both novice and avid mineral collectors. There are two main sections to our mine run dump, the International pile and the Local pile. The International pile contains diverse minerals from all over the world that people can dig through. The Local pile contains hundred of tons of high-grade zinc ore that was derived from the Sterling Hill Mine itself. Much of the ore in the local pile is full of highly fluorescent minerals. There is a shed on the mine run dump which has a shortwave ultraviolet light in which collectors can check their rocks and see if they do fluoresce.

Passaic pit

This collecting area encompasses the floor of the Passaic pit, the “saddle” area leading up to the Noble pit, and a flat area adjacent to the Fill quarry. Collecting back in these areas is only offered on the last Sunday of every month. The specific dates that this is available can be viewed here. Please note that there is a bit of walk to reach these areas so it is suggested that one brings a hand truck or wagon to transport heavy rock back to your car.

The fees to collect in these areas are the same as those stated above for the Mine Run Dump. All of the same rules apply as well except that participants must be at least 13 years of age to collect in these areas.

Night Digs

Mineral collecting at night is an opportunity open twice a year to members of the Museum only. This is held on the third Saturday of June and October, every year. To see the specific dates and times click here. Both the Mine Run Dump and Passaic Pit areas are open.

The same fees, rules, and age restrictions for the given areas apply.
