The Spring Mine is next to the Goddess' Pond on Mother's Hill. You can reach the mine all year round. Just walk up to the hole in the mountain and go inside. Inside the mine you'll find the Ore that you'll need to upgrade your tools.
Each tool upgrade takes a different kind of Ore. If you press the Select button and then scroll over to your tool screen, you can see the color of the Ore you need right below each tool. The tool upgrades require Copper, Silver, Gold, and then Mystrile. You will also find Adamantite and Orichalc. Those two ores are used to make the Makers and Accessories. You won't have to dig very far down in the mine to find the rare Adamantite, just down to the 10th floor or so.
If you dig down to the 100th floor you'll find a Power Berry hidden in the ground. That's a lot of work just for 1 berry!
The Goddess Jewels can be found hidden in rocks on certain floors of the mine. When you find all 9 of the jewels, the Goddess will appear and congratulate you. She'll take the 9 jewels and combine it into the Gem Of The Goddess. The Gem, which looks like a white piece of Mystrile ore, will regain your strength over time if you have it equipped. Just having it in your inventory isn't going to have an affect. Owning the Gem also is a requirement for marrying the Goddess.
At the 255th floor of the mine you'll find the Teleport Stone. It will only appear in the rocks after you have reached your 3rd year on the farm. The Teleport Stone is very handy and allows you to teleport around Mineral Town. There's no need to walk anywhere! Just use the Teleport Stone and then select the location you want to go to on the world map. Instant transmission! You could even use it to access the Lake Mine during any season! You must have an empty slot in the Tool section of your rucksack before you can pick up the Teleport Stone!
After you have found the cursed tools from the Lake Mine and you've have them "blessed", the Mythic Stones will appear in the mine. The stones look like a black tree branch and you can find them on floor 60, 102, 123, 152, 155, 171, 190, 202, and 222. You'll typically only find one or two stones on their specified floors. If you want to upgrade your tools to Level 7 (green) then you'll need to find the stones and then go to Saibara's house. He charges 50,000 G for the upgrade. You can sell the Mythic Stones too for 20,000 G a piece.
