✨💎 “This is more fun than my birthday!” … “Best day of my life!” — Those were the shouts we overheard from a group of three girls who came out to earn their Junior Miner Certificates this week. While we know it probably wasn’t *the* best day ever (😉), it was clear they were having an absolute blast sifting and striking it rich with their treasures!
We love seeing kids light up when they discover something new, and we’re so glad these future rockhounds chose to spend their afternoon with us. 🪨🔍

Sluicing helps kids strengthen their focus, practice patience, improve fine motor skills, and spark curiosity about geology and science. It’s hands-on learning in the best way: messy, exciting, and filled with treasure!

They’ll sift, swirl, and discover hidden gems — and walk away with more than just rocks. They’ll gain confidence, curiosity, and maybe a new favorite hobby.

📍Located at Northern Sand & Gravel’s Warehouse in Sault Ste. Marie
📅 Open Saturdays | ⏰ 8AM–3PM
