This may be a stupid thought, what about freezing it with an upside down can of compressed air and breaking it up with a punch. might take a few cycles of freezing and punching. I did this with a broken tap and it did work for me. Or was I just lucky?

Rookie Mistake- broken drill bit

Use a small nail with the tip ground smaller to punch it from opposite side.
The nail will give and bend into the hole.
Make length of nail just about 1/8 taller than tge depth and place it on something firm like a partial open vice then smack it gently with the biggest happen you have.
Gentle tap with huge mass much more energy transfered than harder hits with small one.

Got it done- used a stout punch (actually a center punch) to beat it in, then drilled a bit larger to give the punch clearance.
Repeated a couple of times until I could simply push it through.
Part is 100% salvaged, as the side I enlarged is going to be drilled on a taper for a gas regulator valve. All's good! thanks to everyone for the ideas. I have a feeling that, rookie mistake or not, this will happen again.........
