have come together on this 200-foot level. As assayed, an ore 

 body is developed on this level 42 feet wide at the northeast por- 

 tion of the level, which carries values of approximately $6 per 

 ton for the whole width. The northeast stope is on the richer 

 ore shoot that occurs in the vein, and has been stoped for a width 

 of about 15 feet. The assays made of this ore shoot showed 

 values varying from $5.82 to $21.54 per ton. The southwest 

 stope of this level is on the richer portion of the ore body, just 

 southwest of the diabase dike, and showed values of $17.82 and 

 $32.52 per ton. This stope is about 12 feet wide. Between 

 these two stopes, a distance of approximately 90 feet, there is a 

 block of ore that has been developed by means of cross-cuts, that 

 gave values varying from $3.38 to $8.30. There is apparently 

 a seam of slate in this ore body that carries very low values. 

 The whole body of ore, approximately 40 feet in width, will be 

 found to carry approximately $5.50 to $6 per ton. The ore 

 shoot to the southwest undoubtedly extends further to the south- 

 west than has been developed. 



It was impossible to get down into certain of the stopes in 

 order to take samples at the bottom of the stopes between the 

 100- and 200-foot levels, and also the upper portions of the 

 stopes from the 200-foot level. Two sides, however, of the block 

 of ore between these two levels have been sampled and assayed, 

 which will give an approximate value of the ore body; and this 

 value has been used in reckoning the ore body. 



250-foot Level. — At the 250-foot level a drift has been run 

 a distance of 47 feet. jST. 50° W. At a distance of 37 feet drifts 

 were started northeast and southwest on a rich v„in or seam of 

 ore. As assayed, this seam carried from $170 to $232 in gold. 

 Portions of it were rich, one 2-foot sample assaying $677 per 

 ton. The material taken out of this cross-cut and the drifts 

 show ore delivered to the mill on my last visit to the mine, 

 January, 1914. The drifts from this cross-cut had only been 

 extended a distance of 6 or 8 feet. A winze was started from 

 the northeast stope of the 200-foot level to connect with the 

 northeast drift on the 250-foot level. On account, however, of 

 the difficulty in keeping good air in the winze, work was stopped 

 on this, and an upraise will be made from the 200-foot level to 

 connect with this winze.
