SWE has only 67m shares on issue so in theory has the best chance to rise more than the above 3, they also have excellent strategic tenements in the east african rift system surrounded by majors who have had discoveries.
they can go up and they also can go down, but at 17c SWE is only valued at $11.5m so at this point in the game downside would be very little compared to the upside.
