Dianor updates on Mori JV property


by Sarah Wilsdon

Dianor Resources Inc., an innovative exploration company focused on advancing diamond exploration properties in Canada, in conjunction with its joint venture partners Metalex Ventures Limited and Mori Diamonds Inc. have received complete results for 13 drill holes drilled on the Mori joint venture properties located 3 kilometres north east and north west of the Leadbetter Diamond Property in the Wawa area of Ontario.

Informing share holders, the JV partners said that greater than fifty percent (52.4%) of the 5,216 diamonds recovered were coloured diamonds. The coloured diamonds range from brown (26.8%), grey (14.0%), yellow (5.5%), green (5.1%), orange (0.8%), purple (0.1%), amber (0.1%) and black (0.1%) .

One pink diamond was also recovered. The ten largest diamonds recovered were commercial sized (+0.85mm) coloured stones (8 brown, 1 yellow and 1 grey) that range in weight from 1.0583 to 2.6327 milligrams.

Natural fancy coloured diamonds are very rare and expensive with orange and purple amongst the rarest and most desirable colours. The main host rocks are conglomerates of Archean age, 2.697 billion years old, unique and amongst the oldest diamond bearing occurrences in the world. The NQ drill cores were processed by autogenous (attrition) milling at the CF Minerals Research Limited laboratory in Kelowna, British Columbia to recover indicator minerals followed by caustic fusion to recover diamonds.

The coloured diamonds recovered ranged in size from 0.075 to 1.32mm and were present on all screen sieve sizes from +75 to +850 microns.

The colour characteristics of the diamonds recovered from the drill core on the Mori East block consist of 47.6% white stones and 52.4% coloured diamonds. The percentage of white to coloured diamonds was consistent in each of the drill holes with little variation between the holes.

Minor variations occurred between the percentages of each colour type in different drill holes but overall the following order of abundance was found brown greater than grey greater than yellow greater than green greater than other colours (orange, purple, amber, black, pink).
