No credit to me, just a link to another great guide by Catnip over on the Steam Community forums.https://steamcommunity.com/sharedfiles/filedetails/?id=94322...
Following this guide will net you the "Beginner Prospector", "Experienced Picker", and "Mysteries Collector" achievements.
Like many other Artifex Mundi games this one does have multiple points-of-no-return. So you will want to make sure you grab the collectible (Father Trace) on each screen as you get there.
One note: There will be screens where a scene or conversation occurs before you can interact with the background/pick up the traces. This is always safe so don't worry.
