Marmota Energy (ASX: MEU) has intersected sulphides at two more target anomalies within its Durkin copper-nickel project in the Grawler Craton, South Australia.
Notably, the result continues to reinforce the potential for a large-scale shallow intrusive system that may have been disrupted by several faulting events
It also brings the total to four target anomalies at Durkin that have intercepted sulphide zones from shallow depths during this first pass drilling program.
Four recent drill holes located within the main Durkin target intercepted mafic rocks containing sulphides from shallow depths.
These were focused on anomaly areas associated with the main outcrop zone to test copper-nickel anomalous zones of outcrop identified from previous surface sampling as well as specific geophysical characteristics and structures identified through surveys completed over the area in late 2012.
This zone extends for about 1.5 kilometres and is located on the western side of the fault zone that is believed to have acted as a pathway for a potentially mineralised intrusive system.
The depth and lateral extent of mineralisation at these new anomaly areas is open in all directions.
The mafic rocks intercepted in these recent holes are similar to those seen in previously reported drill intercepts with preliminary on-site geological observations of the sulphides present interpreted to be pyrite, chalcopyrite and pyrrhotite.
Further mineralogical and petrological assessments are planned to determine the exact sulphides present.
Samples from the Durkin drilling are being processed and will be submitted for laboratory assay.
Planning is underway for a follow-up diamond drilling program that will include the extension of two drill holes that had ended in sulphide mineralisation.
The reverse circulation rig will now relocate to the Indooroopilly project to commence the drill testing of shallow Archaean gold targets as planned.
Marmota had $2.45 million in cash as of 31 March 2013.
