Remember, in 2017 Northington Partners gave NZOG a valuation range of 78 - 93 cents per share. That was just based on existing tangible assets, did not take into account Barque or Ironbark.
Northington will be engaged to provide a value estimate again as part of this process. I don't see how the value could have changed much from 2017...nothing has happened to the existing assets, and oil prices are up.
