Reverse circulation (RC) drilling was used to obtain 1 m samples, which were reduced in size to produce a sample of approximately 1–2 kg in weight, which were ticketed prior to dispatch to the analytical laboratory. No further discussions surrounding RC drilling were documented by the previous operators of the Koongie Park project. The Competent Person considers the diamond core and RC sampling methods to be appropriate for the style of mineralisation. Drilling techniques Drilling conducted at Onedin is as per the table below. Diamond drillholes are either HQ or NQ diameter. HQ holes were used for metallurgical testwork and NQ holes were used to support the Mineral Resource estimate. The rotary air blast (RAB) drillholes were not used in the Mineral Resource estimate. The Competent Person considers the diamond core and RC drilling techniques to be appropriate for the style of mineralisation.

Diamond core recovery was generally excellent. With high recovery, the relationship between recovery and grade was not an issue. The Competent Person considers the level of sample recoveries to be appropriate for supporting the Mineral Resource estimate. Logging RC chip samples were geologically logged to a level of detail sufficient to support the Mineral Resource estimate. All diamond drill core sampled up to 2006 was relogged by a single, experienced geologist to ensure consistency in the geological logging. The same geological logging template was used for subsequent diamond drilling up until the preparation of the 2009 Mineral Resource estimate. Photographs of all core were taken. The Competent Person considers the geological logging procedures to be appropriate for the style of mineralisation. Subsampling techniques and sample preparation Diamond core was cut in half using a diamond saw, with one half of the sample bagged for transportation to the analytical laboratory. No documentation is available regarding the sampling of RC drillholes. It is assumed that procedures adopted were to industry standard at the time of drilling. The sampling techniques are considered appropriate such that the samples could be used to support the Mineral Resource estimate. Field duplicates were not utilised for the RC drilling. The Competent Person considers the sampling preparation techniques and sample sizes are considered appropriate to the grain size of the material being sampled. 6.
