TARGET AND RATIONALE
|
- Five known kimberlites, four diamondiferous (uneconomic)
- This percentage (80%) of diamondiferous to barren pipe is much higher than the global average of 14%
- Located in a deep part of the Superior Craton
- This craton seems exceptionally fertile for diamond mineralization with commercial grade kimberlites being found in several areas (Victor, Renard)
- The exploration target is commercial grade kimberlite hosted diamond deposits, these may occur both bebeath and within the paleozoic platform cover.
- They can be explored for using aeromagnetics.
|
|
METALEX WORK
|
- Aeromagnetics flown over 14,500 sq. km.
- >500 aeromagnetic anomalies, 118 high priority
- >23 aeromagnetic anomalies drill tested so far
- 2 diamondiferous kimberlites: (T1 and U2)
- >390 ton bulk sample complete on each T1 and U2 pipe
- Drill testing of regional priority aeromagnetic anomalies in progress.
|
|
INFORMATION ABOUT T1
|
- Modelled size 200X180 metres (similar to Ekati Panda Pipe)
- Kimberlite intersected from 137 to +300 metres
- 4,336 kg of kimberlite processed yielding 1,870 (4.2x the grade of Victor)
- 59.3% of the diamonds are white
- Encouraging ratio of macro to microdiamonds
- 60% of the diamonds are white, 30% "Gem" colour
- The DeBeers’ Victor mine, (80 km to east) contains 25-28 cpht at US$300/ct and in ground value of C$2 billion (Victor is dominated by white diamonds)

INFORMATION ABOUT U1/U2
- A 28,620 line kilometre airborne geophysical survey was flown in late 2006. A total of 34 targets were identified by the survey and have been staked. Priority targets were drill tested resulting in the discovery of 3 new kimberlites (referred to as U1, U2 and U2NW).
- Initial core drilling of U2 yielded 17 diamonds from a 142.82 kg sample. The diamonds have a coarse size distribution and are predominantly gem quality similar to those recovered from DeBeers’ Victor Mine.
- Five NQ inclined dileneation holes completed on U2 indicating the kimberlite is approximately 9-10 hectares in size.
|
|
|
|
|
|
|
|
|
|
FUTURE WORK
- Complete processing of T1 bulk sample and then U2 bulk sample immediately afterwards.
- Parcels of recovered diamonds from each bulk sample will be submitted to independent appraisers to determine the average value of the diamonds from both pipes.
