Antipa Minerals (ASX:AZY) has identified three conductors following downhole electromagnetic survey as part of Phase I exploration, focusing on the recently discovered Calibre gold-copper-silver deposit at its Citadel project in Western Australia.
GEM GEM Geophysics downhole electromagnetic (DHEM) survey of Calibre drillhole 12AMD0032 identified three electromagnetic conductors situated within the stronger magnetic anomaly.
Two of the three conductors, combined, are compatible with the DHEM conductor modeling from 12AMD0029. The third conductor is interpreted as being intersected by 12ADM0032 within 15 metres of the end of the drillhole.
The survey confirms that the 12AMD00032 just clipped the upper southeast edge of the conductive zone, with the survey defining the potential location of several, more strongly mineralised sulphide zones within the very broade Calibre gold-copper-silver-tungsten mineralisation.
The three conductors have been modeled by Antipa's independent geophysical consultants, Resource Potentials Pty Ltd, as northwest striking and dipping towards the southwest, with a combined dip extent of 290 metres.
This modeled orientation is compatible with the dominant mineralised vein orientation observed in the drilling.
Antipa is also progressing the diamond according to schedule, with the first drillhole 13AMD0033, collar located approximately 97 metres west of 12ADM0032.
The testing the zone of coincident DHEM conductivity and stronger magnetic anomalism is due to be completed through the course of this week or next.
One drill rig will be utilised to drill up to 2,000 metres of diamond drilling and is expected to continue for approximately one month.
Additional geophysical surveys, including a high resolution, deep penetrating fixed-loop surface electromagnetic (FLEM) survey, are planned to be conducted at Calibre over the next few weeks.
Antipa's Citadel project covers 1,714 square kilometres of prospective tenements and is located about 100 kilometres north of Newcrest Mining's Telfer gold-copper mine.
The project also includes the gold and copper Magnum deposit, where a maiden resource of 415,000 ounce gold, 641,000 ounce silver and 77,000 tonnes of copper was defined last year.
It has also made priority application for an additional 1,330 square kilometres of exploration licences called the North Telfer project, the granting of which would bring its tenements just 20 kilometres of Newcrest's Telfer project.
