tion underlain and surrounded by Gros Cap greenstone. As the siderite is not in large amountin the formation here, it would seem quite possible that at the western end of this formationtest pits might reveal a body of ore. East of Parks lake the range continues for about twomiles and was carefully examined as far as Kimball lake. In this distance the formation occursas banded grained silica with more or less pyrite and small quantities of siderite. The drill hole under the hill from the end of Parks lake showed)nothing different from whatcan be seen on the hill top, but if there be any deposit here it will probably be at the contactbetween the iron formation and the underlying~green~schists,~and notin the formation itself. 174 Bureau of Mines Report No. 5 The four small patches of iron range shown on the map to the north of Parks lake areprobably represented a little too large, their exact distribution not having been worked out.They are too small to contain important deposits of ore.

Fig. 2. Longitudinal section Chandler iron mine, Vermilion range, Minnesota. (Van Hise) 1901 The Michipicoton Iron Region 175 Analogy with Vermilion Range. Given herewith (p. 174) are two figures of the Chandler mine at Ely, Minn., reproducedfrom Van Hises recent report oh the Iron-Ore Deposits of the Lake Superior region. In the case of the Chandler as shown in Fig. 2, (which is a longitudinal section of themine) green schists pitch rather steeply to the east. Fig. 1, which is a section at right anglesto Fig. 2, shows the greenstones on both sides of the iron bearing formation and the concen-tration of the ore at the bottom of the trough. The ore reached the surface as is shown inFig. 2 as a comparatively small area, and this was covered by drift, but following it down theore body increased in thickness and also in width. Just east of the Chandler are the Pioneer, Zenith and Savoy mines. The Pioneer pro-perty showed on the surface only hard banded jasper entirely without ore. Noticin
