Centurion Minerals Ltd. (TSX VENTURE:CTN) ("Centurion", "the Company") is
pleased to announce encouraging gold assay results from initial drilling of the
Zulham epithermal gold prospect within the Banda Raya property in Northern
Sumatra, Indonesia. The holes were designed to test the continuity of
north-trending, near-surface, mineralized breccias and wall rocks that have been
previously reported. Two hand-held mobile drill rigs capable of drilling 5.5cm
diameter core to a maximum depth of 15 (m) metres have been utilized to drill 13
holes to date (Table 1). Results indicate that the breccia is the most favorable
host rock for gold mineralization.
Highlights of results received to date include:
Hole ZWDH-08- 5m @ 2.76 g/t Au from 3.5m, including 4m @ 3.44 g/t Au from
4.5m
Hole ZWDH-09- 3.2m @ 1.79 g/t Au from 1m, including 1.9m @ 3 g/t Au from
2.3m
Hole ZWDH-04- 2m @ 2 g/t Au from surface
Hole ZWDH-07- 2.2m @ 1.19 g/t Au from 2.8m
Hole ZWDH-05- 2m @ 1.02 g/t Au from 8m
Intersections are reported as down-hole lengths.
Gold mineralization in the drill holes and in previously announced channel
samples, extend the gold mineralization for approximately 300m along the
structure believed to control the mineralization. In addition, three Breccia
boulders located on a ridge crest a further 200m to the north, yielded 20 g/t Au
from a 1m channel sample in one boulder, and 6 g/t Au and 3 g/t Au from rock
chip samples in the other two, respectively. All of these results are indicative
of potentially large epithermal gold mineralization at the Zulham prospect.
In-fill short-hole drilling is ongoing and the Company is preparing for a
first-phase deep drilling program to test the extension of the breccia zones.
The Zulham prospect is located approximately 1 kilometer northeast of the Keladi
prospect wherein past explorer, Highlands Pacific Ltd., reported nine rock chip
samples that returned between 2 and 27 g/t Au over a 500m long vein system.
Centurion geologists have located a 4m wide quartz vein that extends for at
least 100m. An extensive exploration program is underway within the Keladi
prospect and assay results from collected rock samples will be reported when
received.
The Zulham and Keladi prospects, the Simpang Tiga epithermal gold showing
(located about 500m northwest of Zulham) and the nearby Geudob gold-rich
porphyry-type occurrence lie within a 4 kilometer area along the Miwah-Menawan
lineament, which is the prominent structural control for gold mineralization in
the region.
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.
