Then, maybe it's about stats: perception for find resources and endurance so your character can work out longer, bc you can't mine forever (same goes for chopping wood). If that isn't the case, I don't know other explanation.
Aiodos I already figure it out, have to find the Diabosite in another place then show it to Blake, then you can start minning and continue with the Full Moon quest, a little desperate but finally can move on
