When mine broke it took months to raise the price of mineral to what it now, becouse nev is a very low evolving game (people had their tock, not all mine disapeared at same time...)
Now is going to happen the same, now there are new mines although but, maybe they arent till enough for an adecuate mineral production (it will take some time but eventually will happen), most are not commed so their production is not shown in the market, then there is people stocks wich theyll want to rebuild and then we have to wait to the price to start getting low (wich will take some time too).
You wont notice thi on market until a few month from now.
