    Hi Brett,

    The Report you mentioned was prepared for Xstrata Copper Exploration by the late Roger Majoribanks, who was a consultnt in economic and structural geology.

    Roger Majoribanks carried out the survey in September, 2010.

    One of his conclusions was that in the Narraku area two distinct Sequences of metasediments are exposed, separated by a regional D1 thrust fault. Boh Sequences have been affected by D2 deformation, resulting in a regional,
    N-trending structural high.

    In a 10km wide, NW-trending structural corridor between the Narraku Granite and the Duck Creek Anticline, a concentration of D3 ductile folds and brittle faults have produced F2/F3 interference folds and displaced the D2 structural high by around 5km in a sinistral sense.

    There is an abundance of copper occurrences in the D3 strucural corridor. The most significant of these is Las Minerale.

    At Las Minerale, a dilational jog on a sinistral NW-tending D3 strike-slip fault contains high grade copper sulphide mineralisation. The jog results from fault refraction across an intrusive dolerite.

    Las Minerale provides a structural model for assessing other copper deposits of the region.



    cheers,

    Max
