Zama Result Timing15 Jan 2019 20:52
So last Thursday: "The well has encountered the main Zama reservoir and is currently drilling ahead as planned."
Already into the reservoir interval at that time, but in Zama 1 that was a monstrous 344 meters thick, so down dip looking for OWC might be thicker.
Whilst it's possible that after 6-7 days they've gone through and logged the first target, I'd be surprised if they have enough for a first RNS.
The main 'upside' to this drill seems to be the deeper Marte prospect. Even less chance of an RNS about that tomorrow IMO.
I think Saturday (copy deadline for Sunday Times) would not have been late enough to plant a story to create an excuse to sell into if insiders had drill findings they considered less good than expected.
