Attention Mr 



Gentlemen: 



This letter contains the requested analyses of the 

 sampll of iine'tailings from the BlackfootRxver above 

 Shouey Gulch that you sent to our laboratory June it. 



To provide as much information as possible about the 

 sample, I have done several things. 



First, in preparing the sample for ^;^l.f,^^;,l^^'''i 

 tracted 358 ml of water from the sample ^y filtration, i 

 tractea jjo mj. ^ „u^,,+ en tr^ PO ner-cent of the total 



estimate this to be about 80 to 9U P^J^^^ moisture 

 moisture the sample contained. B> ^^'I^oying xnt; 

 this way rather than by evaporation, I thought that we 



metals in the water. 



The solid phase of ^he sample was then^dried^to^.^^ 



The sample was divided into two segments with a J°^|5 

 sample Splitter. Segment ';A"/^^.P^i^^^i^i,'° ■.llK'ltt 

 and analyzed for total Cd,Cu,Fe,Ni ,Pb , and Zn, 

 II for concentrations. 



See Table 



Segment "B" was passed through a !f,^f "V.^^ ni 

 separate the various particle sizes. Refer to Table 

 fo? per-cent particle size gradation values. 



Each size gradient was divided into two equal parts.
