Would have to agree with you Chris.

The purpose of this hole would've had different objectives to the other planned ones. As it's a diamond geomet hole they would have been trying to drill through the entire iron bearing stratigraphic units in one go. The purpose being to get core samples from each unit so you can run multiple tests to find out density, lump/fine split, processing capability (e.g. mag sus) of each unit (they don't all behave the same). If they just targeted the shallowest outcropping unit they may have only been able to get enough samples/core to analyse one strata member which wouldn't have maximised the benefit of this diamond hole. Understanding the full stratigraphic sequence of the basin is also important for future stratigraphic interpretations when it comes to modelling and future drilling. it assist the geologist in knowing what they're drilling in real time to make decisions like do we end the hole or drill it further. These decisions save the company a lot of money later down the line.
