I'm on Fabric 1.19.2 and I have tested this with only this mod and Emerald Tools installed. I didn't think to try mining the storage blocks, but I did try all three ores.

Emerald Tools has hammers which mine a 3x3 area. While the extra pickaxes added by this mod mine the potassium and sulfur ores just fine, but the hammers cannot break the blocks. When the ores are hammered the breaking animation plays over and over but the block never breaks.

Could you add the tags to the blocks to make them hammerable? Thanks!
