Turn the first two lemmings into athletes, then have the third bash or mine through the column. Have the first athlete block at the third column, then when the second athlete is about halfway back to the second column, have him mine a ramp down to the floor between columns. If you have done this correctly, he will continue into the floor; once he has gone down far enough that the overhang prevents him climbing out, build so he turns back to the right. Meanwhile, have one of the ordinary lemmings mine through the third column, in the process releasing the blocker. Allow him to make his way to the fifth column, and block him again there. The rest of the solution is a repeat of what you did a minute or so ago. You will get 100%.
