To prepare syrup, combine first 4 ingredients in a small saucepan. Bring to a boil; reduce heat to medium, and cook until mixture is reduced to 1/4 cup (about 15 minutes).
To prepare salad, place cantaloupe and the next 5 ingredients (cantaloupe through apricots) in a large bowl. Pour syrup over fruit; toss gently to coat. Cover and chill 1 hour, stirring occasionally. Toss with mint just before serving.
