Ora Gold Limited announced further high-grade results from the remaining assays of the latest drilling program at the Crown Prince Gold Prospect (M51/886).
The drill holes were designed to test for potential extensions to mineralised zones along strike of known mineralisation to the north-west and south-east.
The Crown Prince Prospect is a high-grade gold deposit within Ora Gold's Garden Gully Project. Mineralisation at Garden Gully is controlled by gold bearing structures located in geologically favourable settings within the Archean-age Abbots greenstone belt. At Crown Prince, where mineralisation is hosted in steeply south dipping gold lodes, these new drill results extend the known mineralisation along strike to the west and east. Crown Prince is located 22 kilometres north-west of Meekatharra in Western Australia via the Great Northern Highway and the Mt Clere Road. The Crown Prince deposit is a structurally controlled, orogenic type and is hosted by more competent doleritic rocks above a strongly deformed and ductile ultramafic package and as stockwork veins along the contacts of intercalated black shale units. Some gold mineralisation occurs in the near surface indurated and saprolitic layers in the lateritic profile as supergene mineralisation. Importantly, in fresh rock, gold mineralisation occurs in quartz veins hosted by chloritized, carbonated and strongly sheared meta-basalt, dolerite, black shale units and quartz porphyry, showing strong sericite-carbonate alteration in the vicinity of the quartz veins. Locally, mineralisation at Crown Prince is hosted within WNW - ESE striking (steep southerly dip) quartz rich lodes. These lodes are offset by N-S to NNE trending shears, which are interpreted to have a near vertical dip or to dip steeply to the west. Movement along the shears is dextral, displacing mineralisation with offsets of around 100 metres. This pattern of offset lodes was not previously recognised and substantially opens up the potential for new discoveries along strike of known mineralization. South-eastern extension of the mineralization- another significant gold lode was intersected in OGGAC457 hole approximately 40m east/north-east of OGGAC456 which previously returned 17m @ 15.75g/t Au from 30m, incl. 6m @ 38.06g/t Au from 41m. This new lode (CVX) displays some distinct characteristics and has returned 23m @ 8.5g/t Au from 22m, including 17m @ 10.73g/t Au from 28m (Figure 2). Several samples have been submitted for petrographic and mineragraphic analyses. These are the best two drill intercepts identified to date at Crown Prince Prospect. The main shear in this area shows dextral movement off-setting the main ore body by approximately 100m to the south-west. Interesting to notice that OGGAC453 which has targeted a SAM (sub-audio magnetics) conductor,
has intersected a wide interval of low-grade gold with a distinctive sheared zone of 6m @ 1.4g/t Au from 40m. The last hole OGGAC558 which was abandoned in mineralization at 55m has returned 1m @ 2.60g/t Au within 54-55m interval.
