Narrative:
On departure at mso, clearance was climb out 291 degree right to 7600' then left turn back to the VOR. After switching to departure they advised us of light aircraft traffic descending through 8600' at kona inbound on runway 11 ILS at mso. This put the traffic at our 12 O'clock position descending on the same radial we were climbing out on. We were at approximately 5000'. We continued our climb out as cleared with all 3 of us searching for the traffic. Finally as we started our turn at 7600', the first officer spotted the traffic passing below (approximately 1000') and to the right. All of this in a non radar environment. Callback conversation with reporter revealed the following: reporter believes the small aircraft was VFR and controller was giving his flight a traffic advisory only in the non radar environment. Reporter was unable to determine if the small aircraft had been given his flight as traffic.

Title: LGT ACFT DEPARTING MSO IN NON RADAR ENVIRONMENT. FLT CREW ADVISED OF SMA DESCENDING FROM OPPOSITE DIRECTION. SMA WAS SIGHTED BY LGT FLT CREW 1000' BELOW AND 1000' TO RIGHT.
Narrative: ON DEP AT MSO, CLRNC WAS CLBOUT 291 DEG R TO 7600' THEN LEFT TURN BACK TO THE VOR. AFTER SWITCHING TO DEP THEY ADVISED US OF LIGHT ACFT TFC DSNDING THROUGH 8600' AT KONA INBND ON RWY 11 ILS AT MSO. THIS PUT THE TFC AT OUR 12 O'CLOCK POS DSNDING ON THE SAME RADIAL WE WERE CLBING OUT ON. WE WERE AT APPROX 5000'. WE CONTINUED OUR CLBOUT AS CLRED WITH ALL 3 OF US SEARCHING FOR THE TFC. FINALLY AS WE STARTED OUR TURN AT 7600', THE F/O SPOTTED THE TFC PASSING BELOW (APPROX 1000') AND TO THE RIGHT. ALL OF THIS IN A NON RADAR ENVIRONMENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR BELIEVES THE SMA WAS VFR AND CTLR WAS GIVING HIS FLT A TFC ADVISORY ONLY IN THE NON RADAR ENVIRONMENT. RPTR WAS UNABLE TO DETERMINE IF THE SMA HAD BEEN GIVEN HIS FLT AS TFC.
