How exciting to be able to visit the only agate mine in Canada! Agate is a semi-precious gemstone with a hardness of 7.5. The Thunder Bay Agate Mine hosts the world's largest agate and is one of only 3 places in the world where the agate is found in vein formation. The mine is located three miles east of the city.

Here you can take a tour of the cutting, polishing and manufacturing area, browse through the gift shop then make your way to the open pit mine. A knowledgeable guide will be available to answer any questions you might have.

The amount of agate to be seen and found is amazing. In certain areas, pointed out by the guide, you can choose stones, pay by the pound, have them polished and own a great souvenir of the Canadian Shield.
