Description

CORE ROCK MINERAL SAMPLE - Mining Drilling Collecting - Maine. Shipped with USPS Priority mail
These 3 rock are very cool, I used a 4” length bit 1” diameter and drilled both sides of a rock almost perfectly matching up, you can see in the middle of each rock where I stopped drilling.
The piece of concrete i used a 8” diameter bit on a piece of 50yr old piece of concrete which a slab chipped off, I thought it was cool so I kept it.
My name is Ryan I buy and find my rocks, I can’t say from where in Maine exactly they came from due to I get mixed up myself where I got them.
