Platinum? (I don't think titanium is a byproduct of nickel ore, but, having found none, I can't swear )As fortitanium, I got lucky (pre-quarry) doing spelunking and found a small vein of Nickel. I saved it until I could properly process it.
Same here really. I have around 60 chrome dust kicking around now, which is, for me, amazing. Eventually I got tired of waiting for my quarries to reach redstone levels and went on a manual-mining run (with a laser drill) and got stacks of redstone for processing.Yeah, chrome is my stainless bottleneck. For a small amount of chrome to make stainless, I can centrifuge redstone, but I'm not making enough redstone yet to centrifuge in large quantities.
I really should stop quarrying from level ~65 down, its totally unnecessary for me at this point. I believe nickel starts at <= 30...
