I just downed a red maple that I'm wanting to get milled into some project lumber, and the stump looks like this - is this an indication of metal in the tree? The markings seem to traverse the length of the tree, as I see the same pattern at the stump, and in the first two logs I've bucked.

Get yourself a Wizard metal detector. They're made specifically for this application.
The 2, I believe, costs the same as a single blade, but the 5 is a couple blades. It'll save plenty of time and headache, though.

It looks like wormy maple.

Doesn't look right to be the blue stain of oxidized steel.  It's too symmetrical for normal steel too.  It has to be related to the type of wood it is

If it was embedded steel, you'd have probably hit an actual chunk of it by now.

Old timers call it wormy maple. Whomever you have rip and plane it will go over it with a detector most likely.
Seems to be standard practice these days.

Thanks for the feedback - I was hoping this might be something like wormy/ambrosia, but the guy with the mill took a look at my stump picture and said it could be metal.  I'm not sure if he has a metal detector but I'm willing to chance having to pay for a band to potentially get some nice ambrosia boards.  This tree was in the forest that we cleared to build our house, and wasn't near any of the property lines where it would have been likely to have had a fence attached to it.

Insects or mineral streaks. Metal (realistically pretty much only iron) is typically much darker and you'd only see it here and there, unless the tree had seen a lot of nails/screws or was was shot with BBs throughout its life.

I find that red maple (acer rubra) around here has a small outer ring of whitish sap wood and the much larger heartwood area is dark like Black Walnut.

Reminds me of cherry in the difference of sapwood to heartwood.

I see photos like OP's and it looks like Sugar Maple does around here not red maple.

Any ideas on why?

Looks like ambrosia maple to me.
It is caused by insects that bore into the tree

Went to the mill this morning - confirmed ambrosia maple!  

My 8' log yielded 109 bd/ft of output - now the long wait for it to dry begins.

On the mill:
