    If you are refering to these "encouraging recent grades?? then these are far from good grades, in fact i would more than likely have higher grades in my back yard IMO

    (263ppm Cu, 0.13% Zn and 10ppb Au)grades reported.

    Example 10parts per BILLION Gold (au) equates to basically nothing as 1 part per MILLION =1g/t, so you must then divide that by 1000(million into billion.

    Cu is generally measures in percentages rather than ppm so no these are not economical IMO.
