Default Radiator leak below petcock - what's going on in there?

I've got an inconsistent drip coming from the bottom corner of my radiator, and I'm wondering if it could be anything other than a crack/leak in the radiator itself.

00' XJ, 6cyl, 4.0, 4X4

I don't think it's the petcock, and I'm tempted to tighten the bolt on the underside of the radiator (a few inches below the petcock), but I'm hoping someone might be knowledgeable of what's going on where I'm unable to see before I start tinkering any further.

Photos attached are looking straight on with the grill removed, and looking down from between the upper hose and battery.

It's making 50mi drives alright - topping out at around 70mph, and easing into my accelerations, and topping off at about 1/4gal.

Just drove less than a mile and dribbled when I parked, then drove it a little over a mile and it dripped a couple drops, then drove another 2 miles and it was dry... which I found to be odd.

Any thoughts?

There are no bolts you should be tightening down there which would stop a leak.

The best thing to do is have the system pressurized and verify where the leak is.
