Head to the quarry's entrance onto the Estan Plains - the badge is on top of a rock to the right of the entrance.
If jumped on before the pawn's can destroy it a crate can be used as a stepping stone up to the top of the rock. Alternative methods include using a frigor ice block, stacking barrels, or any other method suitable for gaining a little extra height from a jump. Double Vault alone may have enough height to reach the edge of the block.
