... from 33<br />
Exploration Reviews (Continued)<br />
Seafield Resources, a De Beers subsidiary,<br />
in joint venture with Placer<br />
Solutions, has commenced exploring<br />
for placer Au on the seabed <strong>of</strong>fshore the<br />
west coast <strong>of</strong> the South Island from<br />
Karamea to Jackson Bay. Geophysical<br />
surveys and sampling are planned to<br />
evaluate a model <strong>of</strong> placer formation<br />
during glacial periods when sea levels<br />
were much lower than at present.<br />
Reviews <strong>of</strong> these and other exploration<br />
and mining activities will be presented<br />
at the New Zealand Minerals<br />
Conference in November: .<br />

and Field Trip in S<strong>of</strong>ia, Bulgaria, from<br />
May 7 to 10 was superbly attended by<br />
both juniors and majors. Our thanks to<br />
the excellent efforts <strong>of</strong> organizers<br />
Menzies, Dimitrov, Davena,<br />
Strashimirov and Bogdanov. Readers<br />
will note improvements in our Swedish<br />
contributions thanks to new correspondent<br />

BULGARIA<br />
Dundee Precious Metals posted<br />
notable intercepts at the “Block 149”<br />
ore shoot located at the north margin <strong>of</strong><br />
the Chelopech high-sulfidation Cu-Au<br />
deposit, where holes <strong>of</strong>fsetting isolated<br />
historic intercepts cut up to 12 m <strong>of</strong><br />
5.2% Cu and 30.8g Au contain visible<br />
gold in addition to the typical Cu-As-Fe<br />
assemblage.<br />
Euromax reports encouraging trench<br />
results from the Srebrna (Rakitovo)<br />
Au-Ag-(Pb) quartz stockwork zone in a<br />
Cretaceous granite porphyry stock,<br />
including 26 m <strong>of</strong> 3.68 g Au and 144 g<br />
Ag within a 1,500-m segment tested by<br />
4 trenches; the zone has been traced<br />
with geophysics by the Bulgarian state<br />
for an additional 3 km south. At<br />
Srebren South coincident with the IP<br />
anomaly is a poorly exposed zone <strong>of</strong><br />
quartz stockwork 600 × 150 m in<br />
quartz-muscovite-carbonate altered<br />
granite porphyry, with up to 30 m <strong>of</strong><br />
2.60 g Au, 25 g Ag in limited rock chip<br />
sampling.<br />
TURKEY<br />
Anatolian Minerals completed 165<br />
holes/28,418 m in 2005 at the intrusion-centered,<br />
sediment-hosted Copler<br />
Au (44 Mt <strong>of</strong> 2.9 g/t Au) in infill and<br />
condemnation drilling; intervals<br />
Recursos<br />
included up to 117 m <strong>of</strong> 4.8 g Au.<br />
Eurasian Minerals, in strategic<br />
alliance with Barrick, announced mineralized<br />
intercepts in all eight holes<br />
from a 965-m diamond core program,<br />
including up to 30.4 m <strong>of</strong> 3.8 g Au, at<br />
its Sisorta high-sulfidation Au target,<br />
northern Turkey; a second 3,000-m drill<br />
phase was started.<br />
Anatolian/Rio Tinto alliance<br />
announced results from further drilling<br />
<strong>of</strong> 18 RVC holes/2,543 m at Kizilviran<br />
Cu-Au porphyry in eastern Turkey,<br />
including an intersection <strong>of</strong> 43 m <strong>of</strong><br />
1.2% Cu, 0.18 g Au, and 0.01% Mo in<br />
the Main Ridge zone, which now<br />
extends up to 500 × 1,500 m. Low-grade<br />
(0.2–0.5% Cu) hypogene mineralization<br />
underlies an enrichment blanket 8- to<br />
80-m thick, averaging 0.7 to 1.1% Cu.<br />
Anatolian’s drill holes at its Ikiztepe<br />
Cu-Mo prospect in European Turkey<br />
returned up to 206 m <strong>of</strong> 0.29% Cu with<br />
~0.01% Mo in mixed skarn and intrusion-hosted<br />
mineralization.<br />
Ariana Resources emerged as an<br />
ambitious new junior in Turkey, purchasing<br />
Newmont’s Sindirgi Au-Ag<br />
low-sulfidation epithermal vein<br />
prospect in western Turkey, as well as<br />
discovering its own Kinik Au by following<br />
ASTER and GIS targets; preliminary<br />
chip sampling returned up to 10 m <strong>of</strong><br />
3.21 g Au within a wider mineralized<br />
zone.<br />
European Nickel (ENickel) reached<br />
several key milestones at its Caldag Ni<br />
laterite deposit by increasing the<br />
resource by 30% from approximately 38<br />
Mt 1.14% Ni and .05% Co to <strong>45</strong> Mt<br />
1.3% Ni, and 0.07% Co, demonstrating<br />
heap leach recoveries which now<br />
exceed 50%, and getting a further vote<br />
<strong>of</strong> confidence as BHP Billiton increased<br />
its stake via exercise <strong>of</strong> stock purchase.<br />
