Aircraft X flew through the Arrival and Departure Areas at 11;500; not talking to ATC. The helicopter came in direct conflict with Aircraft Y on the LINDZ9 departure. The Controller had to expedite climb and rates of turn. The conflict alerts went off on the radar. Aircraft Z was delayed on the ground after; while the helicopter was in the departure area in unsafe proximity to the LINDZ9 track.Aspen has very specific IFR routes that we are allowed to use with the mountains and high MVAs. When VFR aircraft fly through the departure and arrival areas; it is unsafe if we aren't talking to them to verify altitude; intentions and control them to avoid conflict. Aspen needs a Class C Airspace or ARSA to require two way radio communication with VFR's.
