The asteroid appears to be a massive carbonaceous chondrite.
The mineralogy in the dust itself that we kicked up corresponds to what was seen by M Cubed instrument, and also what we see in chondrite asteroids.
Apophis is fairly well characterized and has a very close approach on 13-Apr-2029, although it may not be an LL chondrite after all, and may therefore have a different albedo, diameter (currently 270m), and mass (currently 27 Mt - million tons).
Of course, a common carbonaceous chondrite might contain 25% nickel-iron mostly in the form of metal grains, 10% or more water, and several percent carbon plus everything else needed for life in space.
Even a relatively resource-poor low-iron, low-metal LL chondrite contains 20% iron, significant quantities of water and other volatiles in the form of minerals such as clays, and oxygen to burn.
The ‘what’ was a 46-gram completely fusion-crusted melted exterior fragment of an ordinary chondrite meteorite.
However, there is a good chance that we'll need to ship large amounts of ammonia to the habitat, at least until we can capture the resources of a comet, extinct comet, or carbonaceous chondrite asteroid which should have nitrogen in abundance.
