Prospector's Helper is the ultimate field companion for gold prospectors. Track your prospecting locations and results, track your mining results, view BLM mining claims, and never lose a productive spot again.

TRACK YOUR PROSPECTING

• Log test pan results with color count and pan size

• Record mining sessions with gold weight, time worked, material processed and equipment used

• Calculate gold per hour efficiency ratings

• Add notes and observations for each location

• Add photos so you can back get back to the exact spot

OFFLINE-FRIENDLY DESIGN

It is your option whether to securely sync your data to the cloud as a backup in case your phone is lost or broken. All your data is stored locally first, then syncs to the cloud when you're back online if you turn cloud sync on. Map and layer downloads (premium) means you can go to remote locations and take your maps, active claims overlay and more with you.

BLM MINING CLAIMS LAYER

View BLM mining claims directly on the map. See claim names, types, acreage, and filing dates. Use the active claim overlay to show you where you are not allowed to prospect. Use closed claim locations (premium) to look for spots that might still be productive that you could claim for yourself.

HISTORICAL MINES DATA

Discover over 80,000 historical mine locations from USGS data (premium). Filter by commodity (gold, silver, platinum, copper) to find promising areas near proven deposits.
