Coral Island Mining Guide – How to Unlock Shafts, Find All Ore & Upgrade Pickaxe

The mines hide more than just plain wood and rocks. Here’s everything you need to know about mining in Coral Island.

On Spring 7, a grumpy Mark will let you know you can now enter the Cavern northwest of the map in Coral Island. Thus, your mission kicks off: delve into elemental shafts, free the giants, and snag all the game’s gems just for their sparkle.

Mining is a standard mechanic in farming sim games, but Coral Island features not one but four 40-level shafts to explore. Inside, you’ll find your usual ores, gems, and scavengeables, but you’ll also have to fight several monsters. Here’s how to unlock every shaft in Coral Island and what you can expect to find in each.

How Mining Works in Coral Island

After Spring 7 in Coral Island, head northwest of the farm, past the ranch and the forest to uncover the Caverns. Scott will investigate the ruins inside but won’t dare venture to the lower levels. That’s your job.

At first, only the Earth Shaft will be unlocked. You’ll have to reach the bottom of the Earth Shaft to unlock more mines in Coral Island. This unlocks the Water Shaft, in which you must repeat this same procedure. 

Just because unlocking all shafts in Coral Island follows a similar process doesn’t mean you’ll find the same stuff in every shaft. Each shaft has a set of unique monsters, ores, and gems.

Where is the Blacksmith in Coral Island?

You’ll notice that rocks get progressively harder and harder to break in the Cavern. This might indicate that your pickaxe needs upgrading in the Blacksmith Shop. To find the Blacksmith in Coral Island, open the map and look for the anvil icon in Startlet Town.

The Blacksmith is right next to the Vineyard area and north of the graveyard. It’s open from Monday to Friday from 9:00 to 18:00 and on Saturdays from 9:00 to 14:00. Don’t go knocking on the Sanchez’s door on Sunday; they won’t be there. Here’s what you’ll need to upgrade the pickaxe:
