The 20-year-old is a dynamic, hard-working and creative midfielder who has made fifteen first-team appearances for County in all competitions this season.
Owen-Evans signed his first professional contract with The Exiles in 2014 aged 18.
He made a handful of appearances that season, making his debut as a second half substitute against York City in April 2015.
After a successful loan period with Truro`s league rivals Gloucester City, Owen-Evans returned to The Exiles as a promising young player with a point to prove.
He will arrive at Truro in time to help the White Tigers with their play-off push.
