ransom k] LODES OF SAVAGE BASIN. 213 
About 150 feet southwest of the Japan lode lies the Whale vein, 
striking N. 40° W., and therefore a member of the same generally 
parallel system of veins to which belong the Tomboy, Iron, Japan, 
and Morning lodes, with others yet to be described. The dip is south- 
west at 75°. The Whale is a small vein, seldom over G inches wide, 
and consists of solid white quartz carrying some free "gold. It has 
been worked near the surface and has produced some rich gold ore. 
It is cut in the Climax tunnel, an unused upper level lying east of the 
Flora vein. The Climax crosscut also continues into the Japan lode 
(here called the Climax) and en to the .Morning vein, 170 feet beyond. 
The andesitic country rock between these veins shows pronounced 
parallel sheeting. 
The Japan mill is equipped with 1 Gates crusher, 2 sets 12 by 20 
Davis rolls, <', 3-compartment Harz jigs, 1 5-foot Huntington mill, 2 
6-foot Wilfley concentrators, and -2 4-foot Triumph concentrators. 
Power is furnished by a 50-horsepower Westinghouse motor sup- 
plied with electricity from Ames. The capacity of the mill is about 
60 tons. The total product of the Japan has been aboul 1600,000. 
Argentina mine. — This is Located on a very prominent lode crop- 
ping near the bed of Savage Creek, just southwest of tin 1 Tomboy and 
Japan mines. The strike of the lode is about X. 35 \\\, and the dip 
75° to 80° to the southwest. The croppings, often stained black by 
oxide of manganese, maybe traced over the ridge to the southeast 
into Ingram Basin and beyond the edge of the quadrangle to the 
northwest into Marshall Basin. It is one of the prominent group of 
strong, continuous, generally parallel lodes of this region, to which 
belong the Smuggler, Cimarron. Tomboy, Japan, and countless smaller 
veins. As early as L882 and 1883 several shafts were sunk on the 
Argentina claim and some rich free-gold ore was taken out near the 
surface, but for many years tin 1 mine lias been idle. In 1900, how- 
ever, the Tomboy Company took hold of the property and drove a 
tunnel on the vein. In August a length of 800 feet had been attained, 
and the whole width of the lode 1 was being milled. 
The lode nowhere shows less than 5 feet of ore, and in places is 12 
and 15 feet wide. The country rock is the San Juan andesitic breccia, 
with some massive andesite. There is no gouge and no regular walls. 
Stringers from the main vein-tilling traverse the hanging wall irregu- 
larly, and the best ore is usually found in this mixture of stringers 
and country rock. 
The ore shows galena, sphalerite, chalcopyrite, pyrite, and some- 
times free gold, in a gangue of quartz and rhodonite. It is variable 
in tenor, but as a whole carries about $16, chiefly in gold, with less 
important values in silver and lead. 
The present work is considered merely as prospecting, and the ore 
removed in drifting has been treated in the Tombo}- mill. 1 
A tramway has since been erected, connecting the Argentina with the Tomboy mill.
