We invite you to take a step back into the old west and come enjoy a little gemstone mining while at Leaders Farms.
The Arrow Creek Mining Company offers an exciting experience for kids and adults alike!
When you purchase a bag of mining rough, it will be your challenge to sift through it in our old-fashioned mining sluice to discover your own unique gemstones or fossils.
Each bag of rough comes with an identification card and a keeper bag so you can take your treasures home and learn about all the different types of gemstones and/or fossils.
These are some of the treasures you will discover!
