The Mine Shaft is an abandoned mine featured in Grand Theft Auto V. It can be accessed in the enhanced version.
The player can enter the mine by destroying the door - it can be done through explosives, RPG, or the Rail Gun. When the protagonist enters the mine, they can find various railroad tracks, dead ends, and mining tools. The body of Isaac can also be found in the mine. A film canister bearing the name of Richards Majestic Productions can be found next to his body, and finding his body solves the Murder Mystery and unlocks two vintage Noir filters for the Snapmatic on each protagonists' cell phones.
The end of left path of the mine appears to continue beyond the wooden barrier, but behind this barrier is just a very small room where the path ends in just a few meters.
