Of course it's getting pumped because of all the news about mining profitability and hard fork fud.
If it is profitable to mine the BCC now, will the miner mine it and then dump it to drive down the price?
Miners don't want to drive down the price of anything they mine - they want the price to rise. So they'll sell slowly, feeding the coins into the market.
Mining at scale takes quite a large investment now. The overhead is tremendous. So, inherently, miners are bullish long term on the coins they mine, so they are selling as little as possible -- just enough to cover expenses and keep their investments growing. So, if we see miners defect to Bitcoin Cash, it's because they are long term bullish.
Or because they are Bitmain and they are manipulating perception!
