THE DRILL SERGEANT: Sipa Resources (ASX: SRI) is about to commence a Natural Source Audio Magneto Telluric (NSAMT) survey over the Akelikongo and Akelikongo West mineralised intrusions, part of the company’s 100 per cent-owned Akelikongo nickel-copper sulphide project in northern Uganda.
Sipa Resources said by conducting the survey it hopes to confirm the shape and orientation of intrusive pipe-like bodies down-plunge in order to optimise further drill targeting.
“AMT surveys have shown to be highly effective in delineating similar mineralised intrusions at depth including Jacomynspan in South Africa where AMT detected the intrusion down to one kilometre below the surface,” Sipa Resources said in its ASX announcement.
“Akelikongo and Akelikongo West are nickel and copper sulphide continuously mineralised bodies located within a pipe or conduit, comprising multiple intrusive pulses of mafic to ultramafic magmas.
“More than 10 additional Akelikongo ‘suite’ intrusions have now been identified as a result of soil sampling and recent field mapping, in a north-north west-trending zone 80 by 30 kilometres in extent from Goma to the Northern Ugandan border.
“Lithogeochemistry and dating of selected rock samples is currently underway with the objective of proving that the suite of intrusions (of which only Akelikongo and Akelikongo West have been tested by drilling) are genetically related and hence also prospective for nickel-copper and PGE’s.”
Sipa explained that the AMT survey will initially be completed over the known Akelikongo mineralisation.
Should it define an intrusion, the company intends extending the survey to up to one kilometre to the north where previous drilling of EM targets AKD003 and AKD012 returned subtly anomalous nickel-copper-PGEs in the host gneisses.
Sipa has interpreted this anomalism to indicate proximity to the intrusive conduit or geochemical leakage from the intrusion.
Should the survey prove successful, Sipa will generate further drill targets at Akelikongo using the data from the survey.
