How do I make Ores not hit each other in Zonix's Simple Sandbox Tycoon Kit?

So, I want ores to not hit each other, so like a cancollide. But obviously they need to be anchored so they wont fall through the map and delete. So how do I make the ores not collide with players or themselves?

Now my question is:

I have done the collision groups, but there's good and bad news. So, good news it works. BAD NEWS is that it breaks the entire game and you cannot pickup objects, place them, etc. And if I disable that then the character falls through the map. So what do I do? I really want collision groups but apparently setting everything in a character as a BasePart ruins the entire game. Here's the game if you want to see, (I am not advertising, do not play if you don't want to) https://www.roblox.com/games/8534013072/Mineral-Acclivity

So how do I make a collision group without players falling through the ground and the game works?
