Here you will find a guide on how to get the Gold Mission Rewards.
This guide will include all of the different objectives in order to get the Gold Rush Trophy / Achievement, which requires you to get around 70 Gold Rewards from various different missions.
MISSION 6) Eastward Bound
1) Pick Up Javier when entering Horseshoe Overlook
2) Complete Mission Within 6 Minutes
This one was easy to get Gold on, just try and make sure to both fix the Wheel during the start of the journey and pick up Javier towards the end, shortly after the cutscene.
Also, remember you cannot run with the Horse until after the cutscene at which point you can then try and make the Horse run faster, making sure to pick up Javier too.
