I'm a bit drunk but what significance does 3 BTC have here?
If you mine solo and find a block doesn't it still pay 25 BTC plus transactions? If you mine in a pool then isn't what matters your rate of finding shares/hour? I can't think of any reason why 3 BTC is relevant to anything - it's 100 GH/S mining for Y*X time or 1 GH/S mining for 100*Y*X time : it's exixtence says nothing about what X or Y is.
Basically when you mine in a shared pool, you get your portion of the block based on how much work you did compared to everyone else to earn it.
In this case, "someone" had mined 3.xxxx BTC worth on Slush and had it sent to LC's now official mining address.
So if it is LC, then they are mining. If not, someone just did it to make them appear to be mining to bank on a price rise.
We will know more as time goes by.
That is where the 3 btc comes from.

Ah cool - good to know I was missing something.
Maybe someone can explain how we know the payment came from Slush and how we know it was generated from mining hardware owned by them? In my drunken state I'm clearly missing how this is better proof than having a miner published on a pool's list of miners with the name 'Labcoin'.
I mean I could show a BTC address that regularly receives 5-7 BTC payments (I send them so I know it exists). What mining power does that prove it has (it has none that I am aware of but does receive other transactions)?
Obviously if the address listed is getting 3 BTC every 10 minutes (and those transfers are directly from freshly mined coins) then it strongly suggests it has a bit over 10% of network hashing power but I sense that isn't the case.
EDIT: Let me clarify my point. Right now my fund (LTC-ATF) has 77.209 BTC on Bitfunder. If one of my investors asked me to prove it (which they are perfectly entitled to do) I'd screen-share, log in to Bitfunder and show them a balance of 77.209 BTC. I would NOT show them a BTC address that had an incoming transaction of 77.209 BTC and ask them to accept that was from Bitfunder. Do you see where I'm coming from? There's a HUGE difference between proving you have X BTC and proving you have/had X BTC at a specific place/from a specific source. Doubt anyone thinks Labcoin people couldn't RAISE 3 BTC (anyone with a net connection should be able to come up with 3 BTC in a few hours) - issue is whether they actually mined it. And I'm not grasping where the proof is that it was mined - I'd happily stipulate that I agree they can control an address with 3 BTC in.
