Rox Resources (ASX: RXL) has re-split results from the Marqua phosphate project which has not only confirmed the previous composite assays, but highlighted the potential to define a sizeable phosphate resource with further drilling.
The results also displayed additional zones of mineralisation.
These new results come from the re-assay of individual 1 metre intervals from previous 4 metre composite intervals that showed high P2O5 values, which are from a 29 hole reverse circulation program completed at the end of 2011.
Ian Mulholland, managing director, commented: "The results are roughly in line with what we expected. In some cases we have ended up with slightly higher grades over thinner intervals, while in other cases we have slightly lower grades over wider intervals."
The indicate that Rox have a significant phosphate bearing horizon that extends for over 30 kilometres in strike length.
This strike has only been drill tested at a nominally one kilometre spacing, with closer spaced drilling only in areas of outcrop, or previously drilled higher grades - providing Rox with the opportunity to test this extensive mineralised system at depth.
So far the deepest hole only reached 100 metres, with the majority of testing only to 50 metres.
Mulholland added, "Potential exists for a substantial phosphate resource to be defined at Marqua with further drilling."
Marqua is located in the Georgina Basin which hosts 90% of Australia's hard rock phosphate resources, with the project having an exploration target of 50 to 100 million tonnes at 15-20% P2O5.
