Mr. Suzuki, that's the spirit!

Literal

Suzuki-san, that [of-の] spirit [emphatic-ですよ].

その意気 ('that spirit/drive') is a set noun phrase for encouragement — praising someone for their energy or can-do attitude. ですよ closes the sentence as a friendly/enthusiastic assertion (the よ adds warmth and affirmation). A natural cheer-on response.
