Announcement to ASX

29 March 2021

Borba 1-7 Gas Shows Continue

  • Drilling break with gas shows near top of key target sandstones
  • A gas peak of 68 units (14 times than background) is the latest to be measured with the well drilling with 14.2 pound per gallon mud weight
  • Lower Guinda Formation shows exhibited much improved properties when compared directly to Dempsey 1-15, which flowed natural gas from a correlative interval

Xstate Resources Limited (ASX:XST ("Xstate" or "the Company")) is pleased to announce that it has intersected multiple natural gas shows in zones of mud log described with apparent porosity while drilling below the excellent shows previously reported in the Lower Guinda Sandstone.

A gas peak of 68 units (14 times greater than background) in sandstone at around 8,600 feet is the latest to be measured. The well is currently drilling with 14.2 pound per gallon mud to control the background gas in accordance with good drilling practice, in what is considered to be an overpressured zone.

Drilling is continuing to the multiple remaining objectives, with the next suite of petrophysical logs to be run after reaching the TD of the well in basement rocks at around 9,700 feet.

The characteristics of the Borba 1-7 well continue to be better than previous drilling in the area. The Lower Guinda sandstone mud logs exhibited much improved properties when compared directly to Dempsey 1-15 which flowed natural gas from a correlative interval in the Guinda. The comparison below in Figure 1 shows the Borba 1-7 Lower Guinda Formation to have much improved reservoir potential and gas shows than Dempsey 1-15. The Borba sand is a blockier more continuous sand interval covering over 100 feet.

The rocks encountered as the Borba 1-7 well has penetrated into the older formations below the Guinda Formation have contained beds of high clay content which have slowed drilling progress this last week. This and the need for equipment changes and the removal of the downhole directional drilling equipment, which is no longer needed to finish the well, have resulted in slower progress. However, the well bore is in excellent condition and the drilling is proceeding to the overall evaluation plan.
