Is there such a mountain?

Nobody is certain, actually. We do not have good topographic maps of the
lunar polar regions. (Clementine's elliptical orbit never passed low
enough over the poles to get laser-altimeter data there.) Nor do we have
good overhead photography over the full range of lunar seasons -- the Moon
*does* have a little bit of axial tilt, so a mountain that's in continuous
sunlight in polar summer might get some darkness in polar winter.

Even if you can't get continuous light on the surface, you can probably
come close enough that a modest tower would put a solar array up in
continuous light.
