Appendix 2: Reporting checklist<br />
1.0 - Reporting Criteria for Sampling Techniques and Data<br />
Item Criteria Essential Reporting Queries<br />
1.1<br />
1.2<br />
Sampling<br />
Techniques<br />
Drilling<br />
Techniques<br />
Has the nature and quality of sampling (e.g.<br />
cut channels, random chips, etc) and<br />
measures taken to ensure sample<br />
representativeness been noted?<br />
Has the drill type used (e.g. core, reverse<br />
circulation, open-hole hammer, rotary air<br />
blast, auger, Bangka etc.) and the details of<br />
this <strong>drilling</strong> (e.g. core diameter, triple or<br />
standard tube, depth of <strong>diamond</strong> tails, face<br />
sampling bit or other type, whether core is<br />
oriented and if so, by what method, etc.) been<br />
specified?<br />
Were the core and chip sample recoveries<br />
properly recorded and results assessed?<br />

Yes, Item 13<br />
LG, JFT<br />
Yes, Item 14, the<br />
recovery is recorded in<br />
Gemcom databases<br />

1.3<br />
Drill Sample<br />
Recovery<br />
Were measures taken to maximize sample<br />
recovery and ensure representative nature of<br />
the samples?<br />
SAMREC- (Sect A:<br />
Criteria 3)<br />
Yes, Item 13 and 14,<br />
the sample recovery is<br />
cheked during the<br />
<strong>drilling</strong> and logging<br />
SME- (Criteria B.3)<br />
LG, JFT<br />
Is there a relationship between sample<br />
recovery and grade and has sample bias<br />
occurred due to preferential loss/gain of<br />
fine/coarse material?<br />
The recovery is<br />
excellent and there is<br />
no relationship between<br />
sample recovery and<br />
the REE grade.<br />
LG, JFT<br />
1.4 Logging<br />
Have core and chip samples been logged to a<br />
level of detail to support appropriate Mineral<br />
Resource estimation, mining studies and<br />
metallurgical studies?<br />
CIM-(<strong>43</strong>-<strong>101</strong>-Item<br />
14)<br />
Yes, Item 14, complete<br />
logging information are<br />
recorded in Gemcom<br />
databases<br />
