I am working on a project for receiving a very narrow bandwidth signal
at 60 kHz. One of the design goals is to keep the power consumption to
an absolute minimum. I'm trying to figure out how to run a
pre-amplifier on less than 100 uW. So far I have found nothing. Any
suggestions?

Specifying the output, impedance, and degree of linearlity required
might get a meaningful response.

The Maxim MAX480 opamp will run from a single supply down to 1.6V with
a supply current of less tha 20 uA.

Most of the micropower opamps I've seen run in the range of 30 to 50 uW
quiescent which doesn't leave a lot for output.
