During a training flight for the purpose of NAVAID training; my post solo private pilot student; myself; a CFI; and a backseat observing Private Pilot License student were east of LMO at 7;100 feet. I had made two position reports on CTAF when the student pilot noticed a Canadian registered Mooney immediately ahead and to our left. I prompted the student to make an easterly descending turn as the plane overflew us by less than one wingspan width; and with our wingtips overlapping at approximately five knots over our airspeed (which is significantly slower than a Mooney's normal cruising speed.) Mid air impact was never imminent; but it was truly a 'near miss.' It was never apparent the [pilot of the] other aircraft saw our C172. The Mooney continued northbound.
A C172 with an instructor; student and a back seat student observer aboard suffered an NMAC with a Mooney traveling in the same general direction but closing slightly right to left as it passed over them and continued on its way.
