Here's a comparison of Niobium in our Hawke zone compared to Commerce's Upper Fir zone:


SARISSA NI-43-101 REPORT -HAWKE ZONE
111,552,760 lbs Niobium (INDICATED)
356,960,929 lbs Niobium (INFERRED)

COMMERCE NI-43-101 REPORT -UPPER FIR
42,072,586 lbs Niobium (INDICATED)
70,365,540 lbs Niobium (INFERRED)


FROM COMMERCE RES Investor Fact Sheet Feb 2009:
"At Blue River, Commerce has identified three deposits
and is focused on bringing the Upper Fir into commercial
production. Based on the first 38 drill holes completed
from 2005-2007, the Upper Fir contains a National Instrument
43-101 compliant indicated resource of 14.68
Mt with average grades of 190 g/t Ta2O5 (tantalum) and
1,300 g/t Nb2O5 (niobium) and an inferred resource
of 19.8 Mt with average grades of 188 g/t Ta2O5 and
1,612 g/t Nb2O5."

My Calculations of Commerce's Data:
14,680,000 tonnes x .0013 = 19,084 tonnes X 2204.6 lbs./tonne =
42,072,586 lbs Niobium (INDICATED)

19,800,000 tonnes x .001612 = 31,917 tonnes X 2204.6 lbs./tonne =
70,365,540 lbs Niobium (INFERRED)

I realize that our report contains no Tantalum valuations but keep in mind that the assay results from the D Zone adit samples showed an average 0.0181% Tantalum* which is pretty close to Commerce's results above.
