'mono' label is tricky. I think it means that the mic. audio is mono

Correct. The jack is physically a stereo jack, but the audio path is
MONO (tip) only.
The de facto standard for PC sound cards is to have electret "bias" fed,
via a resistor to the ring. Dynamic microphones normally use mono
plugs, which short the bias. Electret ones normally connect ring and
tip, and phantom feed the power to the element.
