Fantastic! I visited silver mines in Shimane, also gold mines near Mt. Kirishima. The old Japanese techniques are amazing, thank you so much for sharing!

Thank you! The silver mines in Shimane would be a place I'd like to visit too! I'm sure there are refining techniques like this all over the world. I'd like to research them one by one and make a video of them!
