Transactions . n quartz-ankerite veins cutting the Keewatin porphyrite andthe Huronian breccia and associated dykes. The largest vein re-ported from here is about 2i feet in thickness. The quartz iscommonly banded with ankerite and carries sericite, pyrites, andchalcopyrite. The gold occurs both free and in combination withsilver as sylvanite which is later than the quartz and ankerite. From published accounts of the geology of the Porcupinecountry, Mr. Harvief considers this district in geological charac-teristics must closely resemble the Opasatica and anticipates thediscovery of tellurides

The likelihood of discoverini^ tellurides ofgold at localities in the l^orcupine district would appear to bepromising, since Mr. Harvie has recognized the prcsence ofsylvanite on the Quel)ec side of the interprovincial , as is commonly known, contains al)out 24 i)er cent, ofgold, and it is small wonder tluit its reportedoccurrence in any one locality should be the signal for a stamjwdethither. 202 Canadian Tellurium-Containing Ores—Cairnes Mr. :—With the uninitiated it is common to mis-takenly associate tellurium with high gold values.
