Request to Energy Metals

To Whom It May Concern:

We have become aware of a discrepancy in the reported coordinate of a drillhole drilled at Camel Flat in 2010.  In your report ‘2010 Combined Annual Report_EL24453, EL24463 & EL24533.doc’ the drillhole CFD1002 has been given the following coordinates:

Easting	Northing	Comment
736,652	7,722,431	In Table 3 Page 14
736,624.16	7,522,446.37	In Ngalia Regional Collars 2011.xlsx (Appendix 1)

Furthermore, in the ASX Release by Energy Metals dated 14th October 2010, hole CFD1002 was located at:

736,652E / 7,522,431N.

Would you please clarify the correct drillhole coordinate and submit a corrected copy of the relevant section of the report. Also, can you supply:
POSITIONING METHOD
CORE TYPE (NQ/PQ)
CORE FRACTION (1/4,1/2,etc)
DRILLING DATE

The ASX release was done in October 2010, prior to the hole being picked up with a RTK DGPS (accuracy of around 10mm) and the collar coordinates for the hole in the release were most likely from the hand held GPS (nominal accuracy of +/- 5m) 

In December 2010 all the collars for the 2010 exploration were picked up by Brian Blakeman Surveys from Alice Springs with a RTK DGPS with the high accuracy.  I think the collar coordinates in the Appendix are from that later survey.  

The error in the coordinates in Table 3 appear to be the same as the ASX release if the second 7 in the Northing is a typo, which is possible.  Also the body of the report was mostly compiled prior to the accurate GPS coordinated being available.

One issue that to me appears to be a concern and will need checking is the accuracy of the hand held GPS vs the RTK DGPS.  Given the nominal accuracy of both I would not expect the collar coordinates to be 28m different in the Easting or 15m in the Northing.  We will also look at a comparison between the initial hand held GPS and the RTK DGPS and evaluate the quoted accuracy of each method.

The other details ( drill dates etc etc) are answered below in your Email.

POSITIONING METHOD - Positioned by compass (azimuth) and hand held GPS then picked up with a RTK DGPS in December 2010
CORE TYPE (NQ/PQ) - NQ
CORE FRACTION (1/4,1/2,etc) - ½ core sampled
DRILLING DATE – Started 6/9/2010 completed 14/10/2010 
DRILLING COMPANY - Core Drilling, Diamond from surface.
