I've generally tried to view everything from the south..... so the decline entrance is to the right.
The Inventum3d Terrain layer with Drill collars (left hand image) is out of date with the current progress of mine infrastructure on the surface as seen by Sentinel (right hand image).
Adding the Mine infrastructure on the 3d and viewing from way below, you can see the surface terrain detail and how it relates to the decline and underground mine infrastructure:
Zooming in on the decline tunnel and spirals leading to the top of the ore body three groups of vertical shafts are visible. The two closest to the decline entrance are already in situ south of the sand dune lines.
Changing the angle to see the surface terrain you can see where the the next groups towards the end of the spiral, of two and four shafts, are going to reach the surface.
Flipping back to the surface you can see where the red tips of some (but not all) of theses shafts break through the terrain layer - shown with four yellow arrows.
Using a bit of rough and ready reckoning - judging by changes in the colour of the sand and drill collar locations - the two areas where, if they are sticking to the mine layout shown on Inventum3d, surface works should appear at close to the red cross and blue circle locations.
Looking back at the mine infrastructure from above and taking the terrain away the red and blue crosses are shown on the tips of the two groups of vertical shafts. This image is viewed from the north east back towards the decline entrance - in order to show a clearer view of the vertical shafts, spiral decline and the portal entrance.
Someone else with mining knowledge will correct my use of the word "shafts" and explain what each one is for..... and when they are likely to be constructed.
