UPDATE 2-Aurizon says Quebec gold tailings spill is minor
* Miner says it does not expect operations to be affected
* Company says majority of spill stayed in containment area
* Regulators say some liquid escaped into the environment
* Makeup of spilled material not known (Adds comments, detail from Quebec government spokeswoman)
