Please see the attachment from Zinifex....they did not include their test 
results.  Inspection lab results from Aug 6th have been attached FYI.  For 
your comment.

According to their water license, they are only obligated to provide 5 days 
notice before discharge (Phyllis -can we please change this to a minumum of 10 
days, unless already stipulated in their renewal, please and thankyou?)

Also, the water license stipulates the parameters that tailings containment 
area discharges must meet (as per SNP 925-10).  As per Water License Criteria, 
allowable concentrations are:
pH range is 6.0 - 9.5,
Total Lead is 0.10 mg/L (avg) and 0.20mg/L (grab), Total Zinc is 0.40mg/L 
(avg) and 0.80mg/L (grab), Total Nickel is 0.20mg/L (avg) and 0.40mg/L (grab), 
TSS is 15mg/L (avg) and 30mg/L (grab)

According to the three tailings pond (TP) samples I took on Aug 6th, the 
following are in exceedance of the criteria (as per allowable grab sample 
concentration) or elevated (above max. average concentration but below grab 
sample allowance):

Note that in the Taiga lab report, Tailings Pond 3 (TP3) sample is listed as 
"Effluent?".  Exact locations (of sampling points) in relation to SNP(s) can 
be discussed.

TP1: pH=4.64, Lead=0.116 mg/L (elevated), Zinc=0.416 mg/L (elevated)
TP2: pH=4.23, Lead=0.42 mg/L (well above criteria), TSS=16 mg/L (elevated)
TP3: pH=2.92, Nickel=0.169 mg/L (elevated)
