Ann: Zapato-1ST Drilling Update and Option Expiry Reminder, page-120

"Therefore, there could be another 5.4days at 17m/day drilling through ophiliotic conglomerate (hard rock), then another 5days drilling through the Vega Alta Fm (at 50m/day), then the fabled Zapato prospect may finally be realised. Therefore, if I had to bet on it, and if drilling starts again "commence this weekend" ASX:MAY, 25/08/2022, as today's announcement suggests, then I would say, based on the above reasoning, and according to my own calculations, 08/09/2022 is black gold day in my opinion."

Since this was posted, we learnt that drilling was expected to recommence on 1/09/2022 source: 63456301 Therefore, 5.4days at 17m/day, then another ~5days through the Vega Alta Fm (at ~50m/day) would be about 12/09/2022. This assumes a drilling rate of 32m/day from 01/09 to 12/09 to a depth of ~2655m.


Source: 63511529 Interestingly Deus_EX_102's table predicts interception of the target by 08/09 if 50m/day is sustained.


Source: 63344891 VOGC also predicts we are at a depth of approximately the Vega Alta Fm.


Source: 63317863 Another analysis predicts we are also almost near the Vega Alta Fm


Source: 63321151 Modelling predicts we are about to enter the Vega Alta Fm with a presumably lower density. Then we are supposedly said to enter the prospect with a lower density than the current "hard rock".

According to Figure 1 in post: 63317863 we can see that there is only about ~100metres (I calculate 93metres), of the ophiliolitic conglomerate layer left to be drilled through, (pretty logical time to be logging and casing) this supposedly has a calculated mGal of ~2.75mGal. We know "masses of lesser density within the Earth's crust typically cause variations in gravitational acceleration" https://en.wikipedia.org/wiki/Gal_(unit), therefore if the density of that strata decreases this would correspond to the observed mGal data. The Vega alta Fm is said to be approximately 2.42mGal, therefore, we might see a similar drill rate to the last time we drilled through a 2.3-2.4 mGal structure, hence, ~50-65m/day for 254m (Vega Alta Fm).
