Do you know how the weather this winter has compared to past winters? Snow fall, timing of the thaw, average temperatures, that sort of thing? Not looking for statistics so much as your own perception.

Being a bit of a layman, hopefully not the only one here, on the subject of the drilling process, can someone please explain why frozen conditions are vital to the process when they are are on solid ground, as compared to being on a lake?  I believe I have a general idea, but when they are not drilling thru a body of water, I'm not exactly sure why it becomes a weather condition.  

[Kidlapik]

I can only base this on information I know about drilling for piles, which are what the majority of our buildings up here are on. The drillers do not like to drill during the thaw season as there is a lot of water in the ground so any hole that does go past the water table into frozen layer or rock fills up with water which greatly complicates the matter. I would imagine it must be even worse when

I suspect part of the problems during this program..wasn't necessarily about the drilling...but the ability to transfer all that extensive equipment from site to site. These kimberlites are still far enough apart...that with little snow fall to transfer to the equipment...it might make for a difficult and ineffective time to get these across to the other kimberlites. I suspect a decision was

Thanks for that Kidlapik. I wonder what they saw in the sample retrieved from CH-7 earlier on that caused them to continue drilling CH-7 instead of sticking to the plan. Surely once 250 tonnes of CH-7 had been removed, they could have moved to CH-6. They chose to stay with CH-7. Why? My understanding is that they have permits to drill only frozen ground. Any summer drilling will require more

Thanks to those for  considering my question...

[Kidlapik]

I think your right in that they are preparing for a mine and the biggest X factor towards that mine is the CH-7 valuations. They have enough info on CH-6 now to be comfortable with it so they want to see what CH-7 diamonds are worth and the more carats you can provide the valuators the better the results, generally speaking.

The main problem of drilling into prima frost; is not to get the drill bit stuck. Therefore a soluntion of chemicals and saltwater are injected through the drill rods and come out of the drill bit;; thus flushing out the drill cuttings and slurry back up to the surface of the hole. A drill hole can be lost sometimes by hitting a fracture and the bit gets jammed and can not be retrived....

Correct me if I am wrong, but I don't think Childiak is in permafrost. If it is, how deep?

[Kidlapik]

Yes baffin island is all permafrost. Not 100% as to at what depth permafrost is for that area. Though recent studies in Iqaluit have shown that the temperature in the ground is increasing and thus interfering with the permasfrost level. Many buildings that were driven into permafrost 30 years ago are now subjecting to shifting during the thawing/freezing periods.

Yet it was the darn ice age that makes it so hard to find the Kims!

[ekim]

It's the bloody glaciers that chopped off 1/3rd of CH-6 and probably 75% of its value...as it probably did balloon out into that traditional shape. LONG...PGD EKIM

It was really cold, as in colder than the last few years. But was not that much snow fall this year, was a lot of blizzards in Western Arctic with tons of snow over there, just not a lot here.
