Look what happens when DRILL meets Kimberlite
Iciena is soon to be drilling - 29 Targets identified by Magnetic survey and signed off by Chuck Fipke as drill targets. Look what happens in themarket when the drill hits Kimberlite.... Come on Iciena lets get drilling and show we have Kimberlite TOO.

SANATANA DISCOVERS KIMBERLITE ON THE GREENHORN PROJECT - NORTHWEST TERRITORIES
Sanatana Diamonds Inc. has discovered a kimberlite on the company's Greenhorn project, Northwest Territories.
Sanatana received the land use permit on Aug. 23, which gave it permission to conduct a drill program. Camp construction commenced on Aug. 31 and was completed by Sept. 14. The drill was mobilized to the site on Sept. 22, and drilling began on the Sept. 29. Kimberlite (subject to verification by petrology) was intersected at a 5.5-metre depth during the drilling of a vertical hole on the G14 magnetic anomaly. The new kimberlite has been named Dharma. Drilling is continuing in kimberlite at greater than 145 m depth. The drill core shows a volcanic breccia with country rock dolomite fragments in a dark, fine-grained matrix with numerous olivine macrocryst. Drilling on this hole will continue as long as it remains in kimberlite or until the drill reaches the end of its supply of drilling rods at 250 m.
The G14 target was selected as the first to be tested in the drilling program as it presented a 300 nt complex magnetic high measuring 160 m by 100 m at the head of a prominent indicator mineral train in the down-ice till. The indicators in the train include the full spectrum of minerals usually encountered from a diamond-bearing kimberlite, namely pyrope, eclogitic garnet, ilmenite, chromite, chrome diopside and olivine. Electron microprobe results show that many of these indicator minerals have chemistry consistent with diamond mineralization.
Sanatana intends to take 750 kilograms to 1,000 kg of split NQ-size core from this kimberlite for caustic fusion analysis of the microdiamond content. Three to four vertical and angle holes will be completed to achieve this. This drilling will also help determine the true size of the target, and if there is any geological complexity. Heavy mineral concentrate will also be taken from the core with a view to verifying that the indicator chemistry matches that in the indicator train.
Management at Sanatana is pleased by this result as it represents a significant milestone after more than three years of work. Linking geophysical anomalies to geochemistry was the key to this discovery. The company holds at least five other areas outside of the Greenhorn project where it hopes this method will find new diamond-bearing kimberlite pipes. Kimberlite emplacement is usually not a solitary event and kimberlite pipes often occur in fields. On average, a kimberlite field contains 30 members, but the number can vary widely. With this knowledge in mind, the company has been conducting ground magnetic surveys over other potential kimberlite targets in the Greenhorn project area. This work is already demonstrating other kimberlite-like targets that warrant drill testing. The company is optimistic about discovering additional kimberlite pipes.
Weather will limit how much drill testing can be conducted before the poor visibility and cold make helicopter-supported drilling too hazardous. The company will stand down the rig in two to three weeks time to start up again in the new year when spring arrives.
Qualified person
The Sanatana exploration programs are carried out under the supervision of Sanatana's director and vice-president of exploration, Buddy Doyle. Mr. Doyle meets the qualified person requirements (as defined by National Instrument 43-101) with 26 years of exploration experience, 16 years of which are in diamond exploration.
