Boyle Concession Ltd. — The Boyle Concession Ltd., 

 has taken over the holdings of the Canadian Klondike 

 Mining Company; controls and operates the properties 

 of the Bonanza Basin Gold Dredging Co. ; and operates 

 the plant of the Granville Power Company. 



The holdings of the Boyle Concession Ltd. include 

 the Boyle Concession, about 4 miles (6-4 km.) of the 

 creek bed of Allgold creek, and 4 miles (6-4 kn.) of the 

 creek bottom of Flat creek. The Boyle Concession com- 

 prises 6-7 miles (10-7 km.) of the valley of Klondike 

 river to the summits on either side, also Bear creek and 

 its hillsides, and the Klondike River slope of Lovitt hill; 

 in all about 40 square miles (103 sq. km.). The holdings 

 of the Bonanza Basin Gold Dredging Co. include about 50 

 placer claims in a group at the lower end of Klondike 

 River valley and just below the Boyle Concession; nearly 

 all Last Chance creek with adjoining hillsides; part of 

 Dago hill ; a number of placer claims on the upper end of 

 Hunker creek; and some placer claims on Upper Eldorado. 



The operations of the Boyle Concession Ltd., are con- 

 fined at present to dredging. Two dredges were in opera- 

 tion in 1912, and two more were being built. 



No. 1 dredge is an electrically driven boat, with a 

 close-connected bucket-line of 68 buckets, each having a 

 capacity of "]\ cu. ft. (-21 cu. m.). This dredge has a 

 total motor capacity of 350 horsepower and has been oper- 

 ating continuously each season since 1905. No. 2 dredge 

 is an electrically driven boat with close-connected bucket- 

 line of 68 buckets, each having a capacity of 16 -i cu. ft. 

 (•45 cu. m.). This dredge has a total motor capacity of 

 1005 horsepower, and started operating in 19 10 and has 

 since operated continuously during the dredging seasons. 



These two dredges are both operating in the valley 

 of the Klondike on the Boyle Concession. 



The two dredges being erected will be very similar to 

 No. 2, but will have slightly larger hulls and will be 

 equipped with some new features for protection in operating 

 during severe weather. Each boat contains over 1,000 

 tons (907 tonnes) of machinery and required 612,000 feet 

 of lumber in the building. These are being erected on 

 the property of the Bonanza Basin Gold Dredging Co., 

 below the Boyle Concession.
