During numerous personal inspections of the Nolan Creek properties (2007
to 2008) the QP has observed sample collection and sample preparation
practices for lode-style deposits.
On June 13 and 14 and September 28 and 29, 2008, the QP visited Nolan
Camp and examined all significantly mineralized core intervals acquired from
the 2007 and 2008 exploration of the Workman's Bench property. A total of
124 mineralized intervals were examined. The analytical data was compared with
each of the mineralized zones to confirm the elevated antimony and gold values
in the sampled intervals.
Drill core intervals were checked through re-assay and inspection. The QP
is satisfied that the sampling and analysis of drill core was carried out in a
sound manner.
Selected field duplicates of sampled intervals, two from underground
channels, and one from a trench, were submitted by the QP to an umpire
laboratory (Alaska Assay Laboratories LLC) to check analytical results from
ALS Chemex. In as much that the samples are collected by different individuals
at different times and analyzed by different labs, the QP judges that results
from this limited comparison indicate acceptable levels of bias and accuracy
for gold and antimony values and confirm the existence of mineralization.
Note to News Release
Please consider the following information in connection with our resource
estimates for Workman's Bench, which we are disclosing in accordance with
applicable SEC standards and regulations:
<<
- Assumed Prices of US $750/oz for gold and US $1.65/lb for antimony.
- Process Recovery Rates of 99% for antimony and 98% for gold (as
provided by Hazen Research following a flotation test on an
underground bulk sample from the D tunnel of the Workman's Bench
A vein).
- Estimated Operating Costs of US $553/ton, based on operation of a
200 ton per day underground mine.
>>
A cutoff grade of 4% antimony was used in our analysis. A 4% cutoff grade
should be regarded as 4.0% antimony equivalent. No cutoff grade was used for
gold as antimony was the primary commodity being examined, and none of the
resource polygons contained less than 0.05 oz/ton gold.
