Narrative:
Aircraft X was departing an uncontrolled airport. There were several VFR aircraft flying in the vicinity. Ceilings were approximately 2;500 ft. Winds were 130/09. All of our airports were operating in an east configuration. Aircraft X was departing and climbing out. I noticed what appeared to be an unidentified VFR aircraft established on the ILS for the opposite direction runway. I called traffic to the departing aircraft. They did not see the opposite direction inbound. I turned the departure to a 180 heading below the MVA to avoid a mid-air collision as the climb and descent rates of both aircraft were comparable and would have both been at approximately 1;500 ft. At the same place and time. The departure turned and continued to climb without incident. I questioned the pilot on whether the VFR aircraft had made any announcement of their position and intentions on the unicom frequency. The pilot stated he heard no announcements. The VFR aircraft never changed course which led me to believe he was not aware of the departure. I tried to raise the VFR aircraft on the guard frequency as it continued practice approaches; but was unsuccessful.
