Marketwired Canada
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 link to a map of the Nareh prospect exploration
and drilling program can be viewed here:

Assay results from the first three holes in this area returned the following

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.
