The boss at the end of the mine is pretty easy but might take a few goes to get through.

He'll begin by using his right arm this cannot be hurt and will attempt to freeze you, speed over to the top left corner to avoid this.

Next he'll drop bombs switch to fire and smash these towards him to break his shield (first time it takes two hits) you can then beat him up, aim for where the shield was. I kept smashing him and managed to get to his second phase straight away. I also switched off fire to ensure a relentless beating.

After the bombs he'll use his left arm this shoots fire and will ignite any bombs left on the field.
Use dodge to avoid this as best you can, just like before the top corners tend to be safest area to head towards to avoid the fire, bombs are much harder to avoid so try to smash as many into the robot when they appear as possible.

Sometimes his left arm will thump the ground, causing rocks to fall dodging with and moving around should avoid the damage from this.

There are three phases, but he just repeats the above cycle each time.
Each phase requires more bomb hits to break the shield.
If health is getting low eat a sandwich or two and you should be fine.
In the last phase when shield drops he moves away to avoid too many hits just shoot him instead at this point.

This is the boss fight at the end of Temple Mine. Just hit the bombs it drops into its mouth to break its shield, then bash its face in while its shields are down.
