sag4tag, I am not so sure what we should read into Xstrara's testing. I do know their lab does contract work. Most recently they were contracted by Adex; "XPS has been engaged to preform Phase 1 pyrometallurgical test work to determine the options for the extraction of tin metal from tin concentrate". This is at ADE's polymetalic deposit in southern NB.
It would indeed be positive nevertheless if XPS had other interest then just lab work.
