Ifcoals can be procured for smelting purposes, charcoal would be of but little suppose with coals it would take fifteen parts to produce one part metal, allowingthe ore to produce 15 per cent. Then I should judge from the copper produced andindications of the lode opened, as well as from the general appearance of the neigh-bouring hills, that such explorations would in time prove the district to be a dividend-paying mining locality.
