Neither a "jump shift" nor a "jump raise" are pre-emptive.
Since your partner's bid was in a new suit, and "one more than necessary," it was a "jump shift" that showed more than a minimum opening hand; at least 15-16 high card points. Opposite a minimum opening hand, it is good for a minor suit game if you can find a fit. If you similarly have a "more than a minimum opening" with at least 15-16, the two of you are close to the slam zone with a minimum of 30-32. Then the viability of a slam depends on "extras" such as "controls," short and long suits, extra trumps (above eight), or extra strength (above 15-16) in at least one hand.
A "jump raise" from one to three clubs is a "limit raise" showing just below a minimum opening hand, say 10-12 points. Opposite a minimum opening hand, it means that you and partner have at least 22-24 points so it is not predominantly pre-emptive. It does, however have some pre-emptive value, insofar as it prevents opponents from "reopening" a higher ranked suit with 17 points between them at the one or two level.
