  • King River Copper Finds New Mineralisation At Speewah Dome 0 comments
    Nov 4, 2013 1:12 AM

    King River Copper (ASX: KRC) is putting the hammer down at Speewah with 60 holes drilled to date, finding new mineralisation at Catto, (formerly Greys North) located in the Eastern Kimberley of Western Australia.

    Two adjacent holes at Catto have intersected 17 metre and 27 metres intervals with quartz veins carrying sulphides (possible arsenopyrite).

    The current program at Speewah Dome is testing for copper/gold mineralisation in alluvium covered areas where soil anomalies, surface rubble and the geophysical interpretation suggest basement targets.

    Samples from the drilling are being sent to the laboratory from the field and all drill assay results are pending.

    Current program

    In total, 60 reverse circulation holes have been drilled for 1,543 metres, comprising 40 holes for 1,049 metres at Chapman Flats (west of Chapman), 18 holes for 429 metres at Catto (formally Greys North), and 2 holes for 65 metres at Todhunter North.

    Chapman Flats

    At Chapman Flats, infill drilling has commenced and one hole has intersected a 5 metre thick downhole interval of quartz veining with arsenopyrite and oxidised arsenic minerals.

    This vein is interpreted to be a very shallow NE dipping vein set. There may therefore be two veins directions, both NW and NE dipping structures.

    To date, 40 holes for 1,049 metres have been drilled at Chapman Flats (west of Chapman).

    Catto

    The first hole drilled at the east end of the northern line intersected a 27 metre thick interval (from 3 metres to 30 metres downhole depth) that was moderately to strongly quartz veined with sulphides (possible arsenopyrite).

    An infill hole drilled 25m to the west intersected 17 metres (from 3 metres to 20 metres downhole depth) of similar quartz veining with sulphides.

    The current interpretation is the quartz mineralised interval dips about 40° to the SE.

    At Catto, 22 holes are planned on 4 lines to test an arsenic soil anomaly, several rubble areas with copper and gold mineralisation (including a previously reported float sample with 8g/t gold), geophysical VTEM anomaly and a newly found mineralised vein outcrop just east of a VTEM anomaly.

    All holes are inclined 60° to the east into Hart Dolerite units. The current interpretation is the quartz mineralised interval dips about 40° to the SE.

    Chapman Flats

    At Chapman Flats, infill drilling has commenced and one hole has intersected a 5 metre thick downhole interval of quartz veining with arsenopyrite and oxidised arsenic minerals.

    This vein is interpreted to be a very shallow NE dipping vein set. There may therefore be two veins directions, both NW and NE dipping structures.

    Todhunter

    Drilling has also commenced at the northern end of the large Todhunter structures. The planned holes are located north of the main copper and gold discovery (where previously reported quartz breccia gave a maximum of 3% copper and 7g/t gold in separate samples).

    This will target where the Todhunter mineralised faults may extend under cover supported by soil Niton anomalies and a newly discovered outcrop with quartz veins with visible malachite staining.

    The first two holes tested this outcrop and intersected a 20 metre thick downhole interval of quartz veining in three zones with visible chalcopyrite (and some malachite) and galena.

    The central zone is about 3-5 metres thick and has the best sulphide mineralisation flanked by weaker zones 1-2 metres thick.

    Plotting the intersections in the two holes suggests the quartz-sulphide mineralisation has a moderate 50° dip to the west in a fault structure in Hart Dolerite units.
