Ariana announced geophysical  test results from their Kisiltepe project in Turkey.

The programme has successfully confirmed the presence of several potential vein systems in the northern half of the prospect area.


  • Several resistivity and chargeability anomalies, which may coincide with buried vein systems, located to the northeast of the Arzu South vein.
  • One significant new anomaly coincides directly with an area of extensive quartz vein float from which grades of up to 21.1 g/t Au have been recorded.
  • Significant additional exploration upside defined on the prospect.
  • Exploratory drilling programme to commence within days.

Dr. Kerim Sener, Managing Director, commented:

“These geophysical results coupled with systematic sampling have demonstrated the potential for further significant veins to be discovered at the Kiziltepe prospect.  These geophysical anomalies will be targeted by exploration drilling.  The first phase of this drilling is due to commence over the weekend (27/28 March) and its aim will be to confirm the presence of these buried vein systems or their associated alteration.  There is clear potential at the prospect to increase the current mineral resource and to further enhance the economics of the project.”

Geophysical Programme

The geophysical programme described here was undertaken over a 2km2 area covering the northern half of the Kiziltepe vein field in an area where no veins appear in surface outcrop.  Detailed mapping of the area had previously identified the potential for buried vein systems and sampling of one area of extensive quartz sub-crop outlined grades of up to 21.1 g/t Au in composite rock-chip sampling of float material.

Data was collected from nine northeast-southwest oriented Induced Polarisation (IP) / resistivity profiles, which were spaced 180-230m apart and designed to coincide directly with existing geochemical data lines (total length surveyed is approx. 12km).  A pole-dipole array was used with 30m or 60m electrode spacing, using a Zonge GGT-3 transmitter and a Scintrex IPR-12 receiver operating in the time domain.

Several high chargeability and high resistivity anomalies were identified in the two-dimensional inversion models, which are interpreted to coincide with zones containing vein systems and their related alteration.  Zones with resistivities greater than 150 Ohm.m, in places coinciding with chargeabilities less than 10mV/V, were identified as significant anomalies.

In plan, the distribution of the anomalies is broadly coincident along three distinct trends; one in the immediate vicinity of Arzu South (possibly representing a splay), another directly beneath a hill which conceals part of the Arzu structure and one in the vicinity of the Vein 5 structure.  These trends possibly represent new vein systems at depth, which must be tested by drilling.  An initial programme of drilling comprising several short test holes will be focused on certain of these areas.  No more than 1,000m of drilling is envisaged for this initial programme.

Figure 1 showing an inverse model resistivity (top) and chargeability (bottom) profiles on Line 2 viewed looking to the northeast.  Towards the left-hand side of the sections a resistive body is identified which possibly represents a north-south trending splay off the Arzu South structure.  Approximately midway along the section (just to the left of the 480 mark) is a distinct resistive body which corresponds directly with the area of quartz vein float from which several highly anomalous results were obtained in rock-chip sampling.  Towards the right-hand side (near the 960 mark) a resistive body is coincident with a discrete high chargeability anomaly and this does not correspond to any known vein system and represents a new target area for drilling.

All That Glitters: Geophysical Exploration for Precious Metals

Posted by on Sunday, 7 March, 2010

it was a theme of Canadian Exploration Geophysical Society’s a timely and informative full-day symposium which took place yesterday in Toronto and timed to PDAC-2010. A roster of noted industry experts presented papers focussing on exploration and extraction of gold, silver, and platinum group metals. The symposium included an introductory overview of key geological aspects of important types of Au, Ag, and PGM deposits, cover particular geophysical surveys and applications, case studies, and look at promising future technologies.

The companies which made the presentations: Barrik Gold Exploration; SRK Consulting; MB Geosolutions; Condor Consulting; Fugro Airborne; Aeroquest Surveys with Teck REsources; Geotech Ltd.; Zonge Egineering with Terra Res.; Quantec Geoscience; JVX Ltd.; Abitibi Geophysics; SJ Geophysics Ltd.; Southern Geoscience Consultants; Levon Res with Coro Minera and Fritz Geophysics; Geophysical Algorithms; RMIT; Geoscience BC; GSC; University of Quebec; Ontario Geological Survey with PGW.
