CHANGES IN KNOWN GEO GRAPHICAL DISTRIBUTION IN THE NEAR FUTURE
Decreases may occur in Cobalt (Ontario) and in Japan; in Cobalt because of exhaustion of ore, in Japan because of lower output of copper and lead if prices of these metals fall. The Rocky Mountain-Andes output should be maintained relatively at the proportion shown above—Mexico being back to normal in this assumption. This Rocky Mountain-Andes production is all, or substantially all, associated with Tertiary igneous rocks.
The above figures allow in part for the increase in Indian output from the new Burma mines.
