Gold Rush!!! The final challenge

This is a timed challenge!!! Drive the loader into the mine and fill your bucket with gold! Take the gold out of the mine and place it onto the conveyer to place them into the dump truck. From there take the full load to the dump site. There is one special gold piece that will reveal a platinum ball in the mine. Take the ball to the dump site to complete the challenge!!! Keep in mind the bucket tilt will automatically level to the angle you place it. Remember your best score.
