LM-10 and LM-12LM-10 was spud July 31st and was drilled and tested by August 20th:
"The Las Maracas-10 development well was specifically targeting attic oil in the main Gacheta reservoir".
"The Tuscany 109 drilling rig was skidded and has commenced drilling the Las Maracas-12 development well, which will also target the Gacheta and Une Formations in an up-dip attic position".
I think we can assume that LM-12 was spud around August 20th and should take approx. the same amount of time as LM-10 (20 days). With that in mind we are within a week of getting results from this well. Possibly they are holding back the update on LM-12 so they can announce results for both wells at the same time.
