Newer Open Ground Outlet wired from Grounded Metal Outlet

I've discovered the outlet for my gas stove has an Open Ground. It was obviously added as the drywall was never properly patched. Made it easier for me to determined that is was powered off the outlet from the refrigerator about 2 feet away. The refrigerator and another general outlet preceding are both metal and grounded. However, I'm only seeing 2 wires in both of those metal boxes (black/white). From research, I'm going to guess there's a ground wire crimped in the back of the metal boxes somehow and I'm just not able to see/access it. That wiring is pretty tight.
The newer wired box has a ground wire that was cut down to the insulating cover. How could I properly ground this newer outlet?

The easiest is probably goes to be run a new cable since you are only talking 2 foot.

Guessing isn't going to work. You need to use a meter to check from the small receptacle slot to the metal box for 120vac.

If I were to run the new cable, what would I be connecting the ground wire too?

If the meter confirms it's grounded, how do I ground the additional outlet?

Put a green ground screw in the back of the box and attach the ground wire there.
There should be a smaller semi-tapped hole for the green screw to go into.

The new ground needs to be spliced to any existing grounds and the the metal box.

Is the following advise from PJMax not acceptable?

Do I need to connect the ground from the new to the actual ground wire from the metal box?? I don't know that there would be enough of the ground from the metal box to connect to anything else.

Are you saying the only other ground is a jumper from the box the the receptacle ? If so you could remove the jumper and wrap the new ground around the screw and continue to the existing receptacle .
