The rare earth chunk bedrock ore is unminable via large mining drill.
Version X4895

The ore says it's tier 2 and requires 500mb Hydrogen Peroxide. When the drill starts "mining" it, it says it needs Sulfuric Acid.
I've tested this on a creative world, it doesn't work with any other drillbits, and the infinite barrel doesn't insert any fluids into the drill.

Did you set the bore fluid in the large mining drill to peroxide?

No, my bad
