4to - 23 x 21 cm. ; iii - 38 pp. Photographic covers in blue and light beige in a saddle stapled binding. From the foreword: "The report provides some insight into the possible repercussions of environment al control measures that are unique to the mineral industry. It discusses these issues in a comprehensive framework, an element often lacking in the evaluation of environmental control options". One small 'crinkle' to the tail edge of the back cover, else fine.
