When looking at the reprocessing values at the bottom line it's possible to see that all these require significant investment in reprocessing skills to EVE Mobile ISK acquire some value from reprocessing them into minerals. Hemorphite and Gneiss should not be reprocessed at current prices since eve at perfect reprocessing abilities you would not be breaking even in value.

Null Sec ores have seen a bit of a shake up, with Jaspet currently the best ore to be mining for currently with the price changes to nutritional supplements we saw over the week. This is due to it having a large reprocessing output of zydrine and nocxium that are both still holding their value compared to the other nutritional supplements. Crokite and Hedbergite aren't far behind as they are still above 300 ISK/m3 on account of their nocxium and zydrine reprocessing sparks too, but provide less than Jaspet. Bistot, Arkonor and Mercoxit will all go back up in price since we get nearer to T8 and T9, but for the time being it is much better to go after another ores in null sec if you are seeking to offer them for ISK available on the market at the moment.

If you are mining for Bistot Arkonor or even Mercoxit, I recommend holding onto them before their worth inevitably goes up once we get nearer to these high tiers since they're currently limited in use, with megacyte only used for faction cruisers and constructions for Buy EVE Echoes ISK capsuleer outposts and morphite still having no uses until higher tiers.For reprocessing those ores only Jasept, Crokite, Bistot, and Arkonor ought to be reprocessed in their current rates. Hedbergite and mercoxit shouldn't be reprocessed as even with all basic, advanced, and expert reprocessing skills you wouldn't be able to break even at cost.
