Fig. 4.5 Abitibi area, Canadian Shield; 643 (10 km 10 km) cells are based on Universal Transverse Mercator grid. (a) Weight of 27 copper-rich cells is

rounded value of logarithm (base 10) of total tonnage of copper per cell; control areas of 25 cells around Timmins and Noranda will be used for scaling. (b) Out
of 55 binary variables, the one indicating both acidic volcanics present and Bouguer anomaly above average is most strongly correlated to copper weights
