In thesame vicinity are numerous outcrops of chalcopyrite,most of which also contain gold and silver. Thisregion was the scene of considerable excitement andactivity in 1914 and 1915, when the railroad wasprojected through Broad Pass. About 200 menstampeded into the country, anxious to obtain claimson ground reputed to be enormously rich, but, as isusual in such cases, many of them were disappointedon finding that the precious metals did not grow ontrees, and that the ores were complex and requiredthe investment of much time and money to factor of considerable weight was the un-.

A few of the more resolute andbetter informed have held their claims, and now,as the railroad nears completion, their reward is insight. 768 Engineering and Mining Journal. Vol. 108, No. 19 On the Ohio River, fifteen miles from the westfork of the Chuhtna, occur a number of veins out-cropping on ground held by Dr. McCallie and asso-ciates, of Anchorage. I was commissioned toexamine and report on these properties, and toobtain the necessary data made two trips to theregion in 1918, one in the spring by dog team, andthe other in August and September, going on foot several ounces per ton. Copper and lead vary con-siderably, but I obtained 4 per cent copper over awidth of 8 ft. where one of the veins ore, being complex and having the preciousmetals contained in the sulphides of the base metals,will require smelting, and the indications
