$$ ALASKAN MINERAL RESOURCES IN 1906. 
Previous developments at this mine consisted of a shaft 35 feet deep 
on the ore body, with two crosscuts 30 to 40 feet in length, and a 110 
foot tunnel was started to undercut just below the shaft. Under the 
new management the tunnel was completed and a surface equipment 
comprising an aerial tram and wharf was being built preparatory to 
the shipping of ore early in 1907. The mine is at 480 feet elevation 
and 1,800 feet from tide water. The mineral deposit is a low-grade 
magnetite-chalcopyrite body with basic gangue minerals and is less 
than 100 feet in its greatest dimensions. 
Four miles northwest of Kasaan post-office, and half a mile from the 
beach, locations were made in September upon an ore body of the 
Kasaan type. Soon after its discovery this property was bonded to 
a n lining company that was planning to carry on its investigation 
during the winter. 
Developments on the ore bodies at the Copper Queen mine, the 
Poor Man's group, and the Sunny Day group of claims, all situated on 
the Kasaan Bay side of the peninsula, have been suspended, princi- 
pally on account of litigation, and the required assessment work alone 
has been done on them during the year. 
The mines at Karta Bay, on the northwest end of the peninsula, 
have added considerable to the copper production of the island. The ' 
ore bodies are large magnetic masses, in which chalcopyrite occurs in] 
concentrated patches and irregularly disseminated throughout the] 
whole. These are included in an altered dioritic rock which intrudes 
and includes narrow beds of limestone and chlorite schist. The sur-1 
rounding country is comparatively low in elevation, and shaft mining 
and exploration is a necessity. These magnetic bodies have been 
located by magnetic surveys, and the largest bodies of ore are appar- 
ently at the points of maximum attraction. 
The Hush & Brown property, which is connected by a railroad 3 J 
miles in length with the wharf at Karta Bay, has been the mining 
center of the Karta Bay area. A lease of this mine was taken by the 
Alaska Copper Company, and the ore mined, which has amounted to j 
several thousand tons, is shipped to its smelter at Coppermount. 
The deposit is a body of magnetite-chalcopyrite ore carrying small 
gold values and inclosed in a diorite country rock. It is oval in cross 
section, being 150 feet in length and 50 feet in width, and has been 
developed 100 feet in depth. A second ore body from 10 to 20 feet 
in width and of greater longitudinal extent occurs about 150 feet to . 
the northeast, and from it much ore has been mined. 
On the Venus group, 2 miles south of the Rush & Browm mine, a 
large body of pyrrhotite-chalcopyrite ore has been exposed by surface 
strippings and two short tunnels. The ore is low in grade, and little 
work was done on the property during the year.
