Sure, you can do a "rough" re-survey with a compass and tape...
Take a copy of your survey map outside and go to the closest "known" corner near the "lost" corner... lay the map on the ground and orientate it so it best matches with your approximate property lines... you can either use the compass or "eyeball" the angle... then use the tape and measure off from there... Do the same thing with the other "known" corner beyond the "lost" corner and work your way backwards to "intersect" the taped lines... this will approximate your lost corner...
The bearings serve as a means of defining the relative directions of the lines, but have little meaning by themselves. Using a compass would normally entail knowing the declination difference of magnetic north versus true north in your part of the US as most modern/current survey maps will have true north instead... that's why the "eyeball" method may be less confusing to use... though not as accurate..
Good luck on finding it... /w3tcompact/icons/smile.gif
