Marketwired
Dundee Precious Metals Inc. (TSX: DPM)(TSX: DPM.WT) (the "Company"
or "DPM") announced that the results from a deep diamond drilling
surface program have confirmed the presence of massive sulfide and
stockwork high-sulfidation style Cu-Au-Ag mineralization beneath a
sedimentary cover sequence within the immediate near mine
environment at the Company's operating Chelopech Mine.
"The results from this program continue to confirm our belief
that we are dealing with a very large mineralized system at
Chelopech and that we have only just begun to define the extent of
this world class asset," said Jonathan Goodman, President and
CEO.
HIGHLIGHTS
- Multi-disciplinary exploration has identified multiple drill hole
intersections of massive sulfide to stockwork style high-sulfidation
Cu-Au-Ag mineralization located approximately 400 metres and up to 1,000
metres from the currently defined Chelopech ore bodies.
- First pass drilling was carried out on a nominal 150 metre drill hole
spacing within the Chelopech North area (21 DD completed for
16,880.4 metres) and returned significant intersections over a 950 metre
long corridor.
- The mineralized corridor or 'footprint' of the drill intersections is
very similar in size to the 'footprint' that encloses the Chelopech
orebodies confirming the potential of the Chelopech mine environment
to host significant additional Cu and Au resources.
- Several strongly Au-rich intercepts were encountered, for example in
holes PTDD015 and PTDD020, where the Au:Cu ratio is markedly higher
than the typical Chelopech mineralization style.
MAIN INTERCEPTS
Table 1 highlights key intercepts.
In situ copper ("CuEq") and gold equivalent "(AuEq") grades are
based on the following DPM long term metal price assumptions: Au:
US$850/oz, Ag: US$16/oz, Cu: US$2.50/lb.
BACKGROUND
DPM's Bulgarian exploration team has carried out an aggressive,
multi-disciplinary surface exploration programme over the Chelopech
deposit since 2004. Figure 1 shows the location of the project
area. Exploration targets have included both high-sulfidation
Cu-Au-Ag and porphyry Cu-Au systems. The multi-disciplinary
exploration has included ground geophysics (Titan-24 and
magnetics), soil geochemistry, geological mapping, reinterpretation
of historic geophysical datasets together with an intensive review
of the historic exploration database, structural analysis and
diamond drilling.
Review of the historic exploration approach revealed that using
a systematic drill hole spacing increased the probability of
intersecting Chelopech style ore grade mineralization. The use of
appropriate geophysical techniques early in the exploration program
is also a clearly favourable situation when targeting Chelopech
style mineralization.

RESULTS FROM THE DPM DEEP DIAMOND DRILLING PROGRAM
During 2004 the Titan-24 Deep Earth Imaging multi-parameter
(DCIP and MT) geophysical survey over the Chelopech deposit and
near mine environs was completed. A significant amount of
geophysical anomalies were generated from this survey and
subsequently incorporated into a detailed target ranking model for
the Chelopech near mine area. The target ranking process also
included a thorough review of greater than 500,000 metres of
historic drilling within the area of the Chelopech hydrothermal
system.
The aim of the Chelopech North deep diamond drilling programme
was to test the top two highest ranked areas within the Chelopech
near mine environment - these were the Petrovden porphyry-style
area of mineralization (PTDD001 & PTDD002) and the Chelopech
North area.
The Chelopech North area is almost exclusively covered by a
younger sedimentary ('flysch') sequence that ranges in thickness
from 120 to 250 metres.
All samples have been sent for assay at the SGS managed
laboratory at Chelopech in Bulgaria. A full sequence of duplicates,
replicates and internationally accredited standards have been
employed throughout the exploration program as part of DPM's
rigorous exploration procedures.
The drilling has returned significant intersections using a $55
cut off for in situ value from nine of the sixteen pierce point
locations, effectively realizing a 56% strike rate and defining ore
grade high-sulfidation epithermal mineralization, similar to that
currently being mined at Chelopech, within a corridor of
approximately 950 metres x 400 metres located less than 400 metres
from historic development. All significant intersections were
located within the Chelopech Volcanic Formation which is the host
lithology to the Chelopech Deposit. It is important to note that
mineralization would appear to be open at depth and to the west and
east - the Petrovden Fault, a steeply south dipping structure,
closes mineralization to the immediate north of the project
area.
The mineralized corridor or 'footprint' surrounding the new
drill hole intercepts, and which is open in all directions except
to the North, is of a similar size to the corridor that encloses
Chelopech, as shown in Figure 1. The drill results are considered
to be extremely encouraging as they clearly demonstrate the
potential of the Chelopech Mine area to host significant additional
Cu-Au-Ag resources. In addition, the mineralization is within easy
access of the existing underground mine infrastructure. Further
drilling of the volume defined by the surface drilling programme is
best carried out from underground, and follow up drilling will be
planned as part of the ongoing Chelopech resource development
programme.
