Plan Your Trip To The Mine

Make a reservation for your party below.

Note: Reservations are for the Mine location on Highway 38! 

Our Seasonal Mine Location is now closed. Please visit us in Downtown Philipsburg!


Know Before You Go:

This page is 100% dedicated to the Gem Mountain Sapphire Mine location on Highway 38, 22 miles from Philipsburg. If you would like to learn more about our downtown Philipsburg location, click here.

The Mine will be open Wednesday – Saturday beginning May 24th through September 2nd. 


Gem Mountain provides all of the equipment you need to find your own Montana sapphires. Our fantastic team will show you how to wash the gravel and find sapphires.

Gravel Bucket Quantities

Single Bucket

For first time visitors, a single bucket will take one person approximately 45 minutes wash.

For returning customers or those with some experience, a single bucket will take one person approximately 20 to 30 minutes to wash.

If sharing one bucket sounds like your cup of tea, a single bucket of gravel fills the screening tool 3 to 4 times. Sharing with one person will take you each about 20 minutes. 

Lucky 7

Lucky 7 is perfect for any one person who is planning to wash more than a couple of buckets of gravel and is ready to spend a good part of the day with us at Gem Mountain.

This is also a great amount of gravel for a family or small group that would like to wash more than one bucket each.

Lucky 7 is a great value. You are paying for six single buckets, and the 7th is free!
