Pretty much, hematite jasper with quartzite veins.

One thing to keep in mind though, the term "jasper" is generally to be taken with a grain of salt strangely enough. It is widely considered by geologists to be a bit of a "pet name" as opposed to having any geological/mineralogical significance. Technically jasper is just a type of chert or chalcedony depending on the composition. This one I would group in the chalcedonies personally. Here's a good link for you to read:
