On Cle-ellum River.Metallic veins are found also in connection with iron ore on Cle-ellum River. Mr. Burch reports a copper and silver lode, and also two lodes of gold and silver, in this neighborhood. He reports the ores as high grade, of good, workable thickness, and outcropping for several thousand feet. There is a gray ore in the same region, the character of which has not yet been determined. This has already been mentioned as lying close to the iron ore, and may possibly be metamorphosed chalcopyrite. Mr. Burch thinks that the silver ores will run from forty to eighty ounces, while in some spots the richness is very extraordinary. The lead ore in association ranges from fifteen to forty per cent.
Large copper vein in Stevens County.The same gentleman, who is a resident of the Okinagane region, reports a remarkable lode of copper ore running due south across Stevens County, from the Canada line to the Columbia River. It shows a plain outcrop for about forty miles. The vein carries both native and gray copper and a small percentage of silver.
Precious metals on Methow River.Reports, apparently authentic, are made of numerous other veins of metal in the same region, particularly in the valley of the Methow River and the valley of the Okinagane River. The Colville region, beginning fifty miles north of Spokane Falls, is well known as a rich mining centre.
What I know of these regions I learned from the oral or written testimony of men who had seen what they described, and some of them residents of the localities.
The basin of the Methow River has been but little prospected, and although I gathered many favorable items concerning the mineral deposits there, I met but one man who had personally examined the country, and he confirmed the favorable reports. He said the ores were similar to those on the Okinagane, but were more abundant.
The rich mines of Okinagane.The Okinagane country is well known, hundreds of men having been at work there last summer, and some of its mines, particularly the Ruby and Arlington, having become notable for their richness. Among my informants are Mr. Burch and Mr. Thomas Lothian, who both reside on the Okinagane River; and also Mr. J. E. Clayton, mining engineer, who made a professional report on the country, which was printed in the Spokane Falls Review.
The mining district is on Conconnully Creek (misnamed Salmon River), which enters Okinagane River from the northwest, about twenty miles from its mouth. There are two wagon roads to the Conconnully, one from Spokane Falls, with a branch from Sprague, distance 150 miles, on which stages ran last summer. Another road starts from Ellensburg on the Yakima, and is 195 miles long. With an expenditure of a few thousand dollars on the channel of the Okinagane, the mouth of the Conconnully could be reached from the Columbia by light-draught steamers, from which a railway fifteen miles long would reach the mines. Mr. Burch says that he and his father sounded the river, and also the Columbia, and that steamers can start at Rock Island Rapids and go to the mouth of the Conconnully, and, in flush water, can ascend the creek. Mr. Clayton makes the same statement as to the river. The country rocks in the mining districts are of the same character as those associated with the iron ore on Mount Logan and the Denny Mountain—hard metamorphic and plutonic rocks.
