1920 Matachewan Gold Area 59 after which shalloAV cuts were made to penetrate the oxidised surface, dueto the oxidation of ircui pyrites, and also of the iron in the carbonate. A num-ber of separate ore shoots were indicated by this means. This trenching- alsorevealed a number of small irreo-ular porphyry bodies, only a few feet in width, ofreddish and greyish colour, intruding the altered volcanics. The chief rocks in thevicinity of the ore liodies are dark-grey altered basalt and associated frag-mental rock, which, wlien further altered by mineralizing solutions, are light gTeyin colour, and speckled with iron pyrites. To the north of the dark basaltic rocksthere are light-greenish calcareous rocks, which frequently show a fragmental char-acter, and are referred to by H. C. Cooke as rhyolite tutf. Whatever their originalcomposition, these rocks are now readily recognized by their light-green colour.
