East Asia Minerals Reports Indonesia Exploration Progress and
Extensions to Gold and Copper Mineralization
======================================================================
For Immediate release, September 18, 2007 TSXV: EAS
VANCOUVER, B.C. -- Tuesday, September 18, 2007 -- East Asia Minerals
Corporation (TSXV-EAS) is pleased to provide an update to exploration
activities at its Indonesian projects, and report that encouraging gold
and copper mineralization continues to be discovered.
Sangihe Project -- North Sulawesi
Channel sampling in new trenches at the Brown Sugar Zone (in addition
to the 7.8 metres of 15.6 g/t gold and 195 g/t silver reported August
30, 2007) has further extended the mineralization with 12.0 metres of
2.45 g/t gold including 4.0 metres of 5.20 g/t gold, and 10.0 metres of
2.65 g/t gold including 2.0 metres of 9.89 g/t gold. The
mineralization occurs in barite -- quartz breccia. To the north at the
Binebase prospect, Trench BIT-2 returned 35.0 metres of 1.12g/t gold.
The Sangihe channel samples greater than 0.5 g/t gold have been tested
for cyanide leach recoveries. A comparison of gold in fire assay and
gold in cyanide leach are very encouraging. Preliminary cyanide leach
tests of the Bawone samples have returned a 91.2% to 92.4% gold
recovery for oxide and partial oxide material. Binebase samples have
an 85.3% to 94.7% recovery with the extraction rate being for lower
grade gold material.
The Company also reports that Sangihe drilling is progressing well and
is intercepting mineralized and altered rock similar to that reported
in historical drill holes. Two EAS holes have been completed to date,
with assays pending.
EAS hole BOD 1, a twin of historical hole BS-18, was drilled to 145
metres. It intersected a silica-barite breccia zone with pervasive to
massive sulphide mineralization from 29.2 to 75.0 metres, and a
moderate to strong sulphide zone with silica-barite stockworks from
75.0 to 133.0 metres. Hole BOD 2 was drilled to 85 metres and tested a
historical high grade zone (20.2 metres of 3.99 g/t gold and 21 g/t
silver) reported in hole BS-07, a nearby historical hole. It
intersected 22.0 metres of intense vuggy silica--sulphide--barite
breccia from 50.0 to 72.0 metres.
Aceh Projects
Abong Prospect -- Barisan 1 Property -- Detailed historic exploration
data for the Abong sediment-hosted gold prospect, previously worked by
North Limited and Rio Tinto, has been purchased and reviewed. In
addition to East Asia results, the historic data identifies five
mineralized zones. The best of these is the Sarah zone, with historic
channel sample results including 16.0 metres of 3.84 g/t gold, 20.0
metres of 2.04 g/t gold, and 16.0 metres of 3.68 g/t gold. At the
Narara 1 prospect, historic grab samples are reported with "bonanza"
epithermal gold grades, some with visible gold in hand specimen. These
include 16.87g/t gold, 129.0g/t gold, 22.6g/t gold, 21.5g/t gold and
54.9g/t gold. Preliminary rock chip sampling by East Asia has
encountered grades as high as 3.52 g/t gold and 29.0 g/t silver (August
30, 2007 news release). Review of the historic data supports the
previous East Asia observations that the limited past drilling did not
properly test the gold anomalous surface samples. This appears to be
due to the limited understanding of the structural controls to the
surface mineralization (i.e. testing high grade zone away from mapped
feeder structures), and the program being terminated prematurely in
1998 due to non-technical reasons.
Miwah Project - At the Miwah epithermal gold-copper Project, previously
worked by Highlands Gold, ninety-one rock channel and grab samples were
collected by East Asia from a vuggy silica and massive
silica--alunite-clay breccia. Results include 6.0 metres of 3.63 g/t
gold, 6.5 metres of 2.66 g/t gold, 30.0 metres of 1.12g/t gold, and
12.0 metres of 1.33g/t gold. The breccia zone hosting these gold rich
samples is 600 metres by 250 metres in extent, and is essentially
untested by drilling (three shallow holes at the south extreme).
Elsewhere on the property ongoing exploration is focused on improving
the definition of higher grade gold in structures that are
perpendicular to the historic drilling where grades outside the
structures include 71.0 metres at 1.4 g/t gold and 58.0 metres at 1.1
g/t gold.
Upper Tengkereng - Barisan 2 Project - Ongoing exploration activities
at the Upper Tengkereng gold--copper porphyry Project are defining a
series of north to northeast trending dilation features that contain
the better copper values. Better gold grades are found in an east-west
fault that dissects the porphyry mineralization and includes 15.0
metres of 0.51g/t gold and 35.0 metres of 0.76g/t gold, including 5.0
metres of 1.27g/t gold. Thus far, the Upper Tengkereng prospect is
defined for approximately 600 metres long by 400 metres wide,
confirming past Rio Tinto work.
Tangse Project - At the Tangse copper--molybdenum porphyry project,
previously worked by Rio Tinto, ongoing exploration has extended the
supergene malachite-chalcocite mineralization for 150 metres northeast
along strike from the discovery outcrop (30 metre composite chip sample
with 2.85% Cu; July 17, 2007 news release). The malachite-chalcocite
mineralization extends into the feldspar diorite porphyry where
hypogene chalcopyrite-bornite-chalcocite mineralization occurs as
fracture fill in dykes. The dykes are interpreted to represent
apophyses of a larger, mineralized body at depth.
Takengon Project - Current exploration work is focused on semi-regional
follow-up of stream and rock chip sampling anomalies, defined by past
Minorco exploration. Recently reported highlights include 5 metres at
3.37 g/t gold and 5 metres at 1.81 g/t gold (August 30, 2007 news
release).
Samples reported were assayed at PT SGS Indoassay assay laboratories.
