The issue I see with proccing the coin is that I don't think it'll change anything. If he's still chaos aligned somehow, then he likely will just think us foolish (because self-sacrifice is for the weak), and ignore us. And if he's either bound by the dwarves, otherwise working for/with them, or an illusion, then it's the dwarves of Karag Dum we need to convince, not Malagor. And with Borek couching for us they'll likely already be as convinced of our good intentions as they're likely to get. And if they don't contact us of their own initiative, then they'll probably not change that opinion because we helped them out with an attack that likely wasn't a real threat to them anyways.
As for potential actions, I'm of two minds. On the one hand, if Borek's talking with Karag Dum, then waiting a day gives them time to organize and send a response to us, which would be the best, lowest-risk way of figuring things out. OTOH, we don't want to stay here too long, and if we're staying the night we might want to do things like contacting people before nightfall to get more done before the rest of the expedition pushes to leave. But doing that would come with its own risks, so it might be better to wait for any Karag Dum reply that Borek might be able to get sent our way. hard to choose.
