Operating costs were down 1%.Chief executive Ian Harebottle said: "At Kagem production remains consistent and operating costs saw a reduction on the corresponding period last year. In addition, I am pleased to report the quarter saw the completion of two new exciting community projects in the form of new Chapula high school and Nkana health clinic."These new facilities have been incredibly well received and the local communities are already reaping the rewards.
