What is PlacerPro?

PlacerPro is a map for recreational gold prospectors. It rates creeks in the gold country of 22 US states as best chance, worth a look or long shot.

What it does

• Rates creeks and explains each rating: old mines, gold-friendly rock, faults and USGS samples.
• Shows public land, active mining claims and the rules for each area.
• Finds the best-rated creeks near a place you choose.
• Lets you save map areas for use without a signal, and save your own pins.

Where the data comes from

Public records: USGS and state mine databases, USGS stream-sediment and panned-concentrate samples, state geologic maps, USGS stream maps, federal mining claim records and the national public land database.

What it can't do

A rating is an estimate from records and geology, not a promise of gold. It can't see what's in a particular gravel bar, and it can't tell you that you may dig somewhere. Most gold ground in the East is private, and you need permission.

What it costs

A free 7-day trial with no card, then $7 a month or $60 a year.
