Great Northern Minerals Limited (ASX:GNM) has confirmed gold was intersected in every hole in its maiden Reverse Circulation (RC) drilling programme at the Camel Creek Gold Project in Northern Queensland.
Managing Director, Cameron McLean, saidfinal one metre sample results from the 18 hole RC programme has established strike continuity over 700 metres at Camel Creek.
A total of 2516 metres were drilled at Camel Creek testing on nominal 40 metre spacing covering approximately 700 metres of previous mined areas at Camel Creek, which had been mined to an average depth of approximately 25-30 metres.
The new holes, the majority of which will require follow up drilling, were all drilled into the primary zone below the base of oxidation with hole depths ranging from 65 to 197 metres, with an average depth of 140 metres.
Mr McLean said multi-element analysis, as well as gold has demonstrated a close correlation between the higher-grade gold results and anomalous antimony.
He said the original one metre samples have more accurately defined and documented the intersections indicated from the four metre composite results.
The vast majority of the intersections are associated with a strong mylonite zone trending north east and in places up to six metres in width and extending along strike over the entire area tested.
Two parallel zones were intersected in a number of holes highlighting multiple opportunities for further testing.
A follow up RC drilling programme is in the planning stages.
Mr McLean said no deep drilling has ever been completed at Camel Creek previously and this systematic programme has highlighted the continuity of the mineralisation underneath and beyond the previously mined shallow open pits and demonstrated considerable additional potential.
The company also announced that RC drilling is progressing well at the Big Rush Gold Project, where a total of 15 holes for 2430 metres has already been drilled, with initial four metre composite gold results due in the next two weeks. Drilling is ongoing and has been expanded to allow a comprehensive testing of both the southern and northern pits, as well as the follow up of last year’s results at the Central Pit.
A number of systematic holes to evaluate the remnant heap leach pad at Big Rush will be drilled, using a large open hole aircore bit to collect sufficient representative material to allow for test work and evaluation of this large stockpile.
