rocks are granites, porphries, and Laurentian and Huronian rocks and 

 volcanics and over these are superimposed glacial drift from a few 

 inches to several hundred feet in depth. In addition, the region is often 

 swampy, is trailless and a variable jungle. Notwithstanding this, some 

 mining work is in prospect. 



Near Gheen, on Patrick Calahan's homestead, there is a brown stained 

 quartz ledge running in a northeast-southwest direction. It is 400 feet 

 in width and shows 3,000,000 tons of quartz in sight. An assay of occa- 

 sional small seams in this rock gives $10, $20.60, $80, and even $120 per 

 ton. Some drilling has been done in the region, and good findings have 

 been reported. 



A quartz ledge similar to the above is also exposed on Finlander Hill, 

 north of Gheen, showing gold. 



IRON ORE NEAR RAY, MINN , AND FORT FRANCES, ONT. 



Iron ore has been discovered in large bodies both at Ray, Minn., and at 

 Fort Frances, Ont. A wide belt of the iron formation extends in a north 

 and south direction and is mostly continuous on both sides of the Inter- 

 national Boundary line. Companies have been formed both at Ray and 

 at Fort Frances and drilling and prospecting has been done. The ore 

 strip is found about three miles west of Ray and to the north of Fort 

 Frances, though it is believed that the formation is continuous. The 

 drill showings are good. 



PLACER MINING NEAR KINMOUNT, MINN. 



West of Kinmount in both St. Louis and Koochiching counties, Minne- 

 sota, there is a sandy ridge of glacial origin. The sand ranges from a few 

 inches to sixty feet in depth. Below this sand is a granite-porphry ledge. 

 Both the ledge and the sand carry gold. Repeated assays show that small 

 seams in the granite-porphry ledge carry $10.80 or more per ton, and 

 that the sand carries good values in gold. 



The gold in the sand has most likely been leached out of the country 

 rock beneath it and likely, also, been carried, for the most part, from 

 some ledge in Canada, say Mine Centre or the Lake of the Woods region, 

 and deposited there with the sand by some glacial eschar-streams. Both 

 of the regions above contain gold-bearing rocks. 



Gold in this region was discovered in 1910. A party headed by a Mr. 

 E. P. Moorehead, were drilling for iron ore in the region and each time 

 the drill was drawn up it was noticed that the earthy matter was glitter- 

 ing with bright particles. A sample was sent to Doctor Drew of Minne- 

 apolis and he reported that the sample contained gold at a ratio of $9.20 

 per ton. A spring also contained sand that assayed high in gold. 



As a result of the finding of gold here, the Durheim Mining Company 

 was formed vnth Mr. E. P. Moorehead as president. This company pur- 

 chased 601 acres of placer land in township 60 of range 22 in St. Louis 

 county, Minnesota, and 120 acres in township 66 of range 22 in Koo- 

 chiching county covering the gold district mentioned. Since getting hold 

 of the land they have been active in more than a prospecting way.
