Centurion Reports Initial Drill Results From its Badak Property Northern Sumatra, Indonesia
November 07 2011 - 9:00AM
Marketwired
Centurion Minerals Ltd. (TSX VENTURE:CTN) ("Centurion", "the
Company") wishes to report the results from the first three holes
of its ongoing, Phase I diamond drill program targeting copper-gold
mineralization on its Nareh prospect within the Badak property in
Northern Sumatra, Indonesia.
Nareh Prospect: Porphyry Copper-Gold Drilling
Five drill holes have now been completed that tested the
gold-copper-molybdenum anomalous surface rock samples along the
north-western margin of the Nareh volcanic-intrusive complex. A

program can be viewed here:

Assay results from the first three holes in this area returned

Copper-molybdenum mineralization occurs in brecciated and veined
volcanic rocks. Although Hole NA_DDH 1 was stopped at 211 metres
(m) due to the depth limitation of the drilling rig, visual
examination of the core shows encouraging amounts of Cu-sulfide
minerals and molybdenite, which increases with depth. In order to
determine the continuity of the mineralization at greater depth in
NA_DDH 1, a bigger rig was utilized to drill hole number NA_DDH 7
located approximately 30 m to the south. This hole was terminated
at 396 m, and assays are pending.
NA_DDH 2 intersected narrow zones of copper mineralization, and
NA_DDH 3, which was directed toward the nearby Au-Cu-bearing skarn,
also hosts narrow, low-grade copper contents.
Centurion has executed confidentiality agreements with several
mining groups that have expressed interest in partnering and
financing this prospect. The first due diligence property visit has
been concluded and a review of inflowing data by all interested
parties is continuing.
Nareh Prospect: Gold Drilling Targets
The Company has now completed two drill holes on the epithermal
gold target in the Nareh volcanic complex with a third
underway.
-- Hole NA_DDH 5 was ended at a depth of 200 m, the maximum capacity of the
drill rig and it intersected narrow mineralized zones registering 3 m @
0.6 g/t Au and 0.15 % Cu from 5 m, and 1 m @ 0.96 g/t Au from 158 m,
albeit rock channel samples in this area assayed up to 1 m @ 11 g/t Au
as previously reported. Consequently the Company is re-examining the
nature of the mineralization.
-- Hole NA_ DDH 6, collared at approximately 120 m north of hole NA_DDH 5
and directed toward the southwest, was terminated at a depth of 180 m.
This hole was designed to test the continuity of the mineralization to
the west and southwest. Assays are pending.
-- Hole NA_DDH 8 (in progress) is collared approximately 75 m higher in
elevation than NA_DDH 6 and is aimed at intersecting a potential near
surface, high-grade gold zone. Seven rock chip samples in this area
returned assays from 0.1 to 2.2 g/t Au.
Banda Raya Property
Exploration crews have been able to establish initial drill
targets on the Banda Raya property where the Company previously
reported a geological and geochemical survey that resulted in
delineating a 5-km radius gold-copper mineralization complex. This
property hosts epithermal, gold-polymetallic and porphyry
copper-gold prospects. Rock assay results from targeted mineralized
areas, including, a newly uncovered epithermal gold lode system
that so far has been traced for 300 m long and up to 5 m wide, are
being compiled and will be reported shortly. This lode remains open
at both ends. The Company anticipates relocating one of two drill
rigs currently under contract to the project area. Once logistics,
drill pads and infrastructure are in place, Centurion will
implement a focused drill program on these prospects.
Qualified Person, Quality Assurance and Quality Control
Thomas Mulja, Ph.D., P.Geo, and Chief Operating Officer of the
Company is the Qualified Person under National Instrument 43-101
who has supervised the preparation of the technical contents of
this news release.
The sample chain of custody is managed by Centurion Minerals
under the supervision of Thomas Mulja and/or exploration manager
Thomas Dott. Core samples are picked up from the drill site at the
end of every shift by Centurion personnel for direct delivery to
the secured drill core storage house located next to Centurion
regional office in the town of Takengon. The storage is accessible
only by approved personnel.
Intervals of core to be analyzed are split with a mechanized
core cutter in half with one half to be sent to the laboratory for
geochemical analysis and the remaining half to be kept in the
storage for future reference and uses. Samples to be assayed will
remain under the control of Centurion personnel until shipped or
delivered to Intertek Testing and Inspection Services preparation
laboratory in the city of Medan, North Sumatra that is responsible
for pulverization of the samples. The pulps are then forwarded
directly by Intertek personnel to the Intertek Analytical
Laboratory in Jakarta.
Intertek is ISO 90001 and 17025 accredited and employs a
Laboratory Information Management System for sample tracking,
quality control and reporting. In addition to Intertek internal
standard materials and blank samples, Centurion regularly inserts
into every sample batch its own certified rock standards from OREAS
and GEOSTATS, Australia, and field duplicate samples. Gold is
determined with fire assay methods (FA 50), and other elements with
Induced Coupled Plasma-Optical Emission Spectrometry (ICP-OES;
Intertek Codes: IC01 and IC50). Intertek systematically re-assays
selected low, high, and over-limit results.
