check the 2017 proposed drillhole. it is somewhat of a blueprint.
like to see some chlorite and bleeching.
The blue-green alteration suggests the possible presence of dravite, a boron-rich mineral, in the drill core. Dravite is an alteration mineral often associated with unconformity-style uranium deposits in the Athabasca Basin.
this shows some hydro thermal activity.
