Ok, here is the coords and a hotspot screenshot for the Serp spot. I just save it and warp in, I can’t find any portals right nearby into it, but it is worth digging down into it and saving to come back later, worth the 100c to warp once there. One of the best parts about this area is that if working west from this spot, dig tunnels from spots in the wall and keep going, there is really no lava right around there that I’ve seen. Might be some but very little. Can basically wipe it all out with no worries.
I said I’d PM it but I’ll trust folks here to be nice. 
Plus, less a risk since you got some already - if you didn’t need this, just say so and then somebody else reading at some point might want them.
My place is Elysian Fields on Alder. Easiest portal would probably be TNT but there are also ones in places like Legendville Mall and Kindred Bay. From the portal area, head south and go in the tallest tower you see. Plinth at the top. I use these titaniums on Serp myself, best place to buy these once settled in is Nova Golda, Aenea sells them so cheap that you can turn a good profit on selling what you get from them. Better to go gem with a T6 but with a T5 they are great.
