On my trips into New Eden - the biggest change has been Pyerite... 6.72 isk a unit locally on buy-orders. Wow.
Usually my mineral basket buy-price (and my existing stock) is a 2.09 -2.5. So Pyerite has tripled in price inside last few months compared to previous buy prices experienced.
Rest of mineral basket has changed too, with high-end minerals such as Zydrine and Megacyte changing from high prices to relatively low....
My reasons I can determine for this are several fold.
1/ Wormholes - people concentrating mining high-ends only
2/ The recent ganking of Hulks in high-sec - leaving less minerals coming in from this route and refines from drops as a general rule having a low Pyerite count
3/ Less people mining Pyroxies potentially.
Anyone else got any comments on why this may be?
