East Asia Minerals Encounters Additional 200 Metres of 4.11 g/t
Gold in Miwah Channels
====================================...
For Immediate release, January 21, 2009 TSXV: EAS
VANCOUVER, B.C. -- Wednesday, January 21, 2009 -- East Asia Minerals
Corporation (TSXV-EAS) continues to encounter significant gold
intercepts from rock sawn channel sampling at its Miwah Gold Project
located in Aceh Province, North Sumatra, Indonesia. The latest results
have encountered high grade gold from the central part of Block M,
including 20 metres of 14.00 g/t gold, 10 metres of 3.70 g/t gold, 32
metres of 2.41 g/t gold and 20 metres of 1.45 g/t gold, over 200 metres
of strike within the plus 1000 metre long continuously gold mineralized
Miwah zone. Also, rock chip samples with anomalous gold values were
collected from Sipopok, a newly discovered mineralized system located
1.5 kilometres northeast of Miwah.
Miwah Trenching Update
Additional encouraging assay results have been received from rock sawn
channel sampling in trenches at the Miwah Gold Zone (view map at
www.EAminerals.com). Results from the central Block M area returned
consistently strong gold mineralization averaging 4.11 g/t gold across
a 200 metre long, semi-continuous channel. Selected un-cut composite
trench intervals include:
. 20 metres of 14.00 g/t gold (Trench 119);
. 6 metres of 6.19 g/t gold (Trench 121);
. 10 metres of 3.70 g/t gold (Trench 117);
. 32 metres of 2.41 g/t gold (Trench 118);
. 5 metres of 1.61 g/t gold (Trench 115);
. 20 metres of 1.45 g/t gold (Trench 116);
. 34 metres of 0.75 g/t gold (Trench 114);
. 15 metres of 0.61 g/t gold (Trench 112);
. 50 metres of 0.58 g/t gold (Trench 103);
Michael Hawkins, President and CEO of East Asia Minerals Corporation
stated "We continue to be very encouraged by the tenor and continuity
of our rock sawn channel sampling of the huge, well exposed Miwah high
sulphidation epithermal gold system. Miwah is so well exposed at
surface that we are very confident of the overall size of the system,
and as our rock sawn sampling program progresses we are likewise
confident that the overall grade of the system might approach, or
perhaps even surpass that of the nearby world class Martabe gold
deposit."
Ongoing detailed surface mapping and sampling will form the basis for
selecting optimum drill targets which are anticipated to be drill
tested in Q2 2009.
Sipopok
EAS has recently discovered another mineralized zone at Sipopok,
located 1.5 kilometres northeast of the Miwah Gold Zone. Initial rock
chip channel sampling returned anomalous gold values including 12
metres of 0.78 g/t gold, 11 metres of 0.45 g/t gold and 35 metres of
0.33 g/t gold. This sampling has only partially tested a small part of
this new and potentially large mineralized system currently identified
over approximately 1000 by 1000 metres. The alteration facies sampled
was predominantly alunite-silica which is typical of the peripheral
parts of high sulphidation epithermal systems. Follow up mapping and
sampling are required to identify the more productive silicified part
of the system.
Project Background
Extensive surface channel sampling by EAS and a previous explorer shows
that mineralization in the Miwah Gold Zone occurs within a well
defined, one square kilometre zone of high sulphidation alteration.
Better gold mineralization is closely related to a well-defined body of
massive, residual vuggy silica-sulphide forming an impressive
resistant, east-northeast trending cliff traced for over 1000 metres
along strike, averaging 300 metres wide and up to 200 metres high.
Miwah demonstrates many features of the shallow part of a high-level
high sulphidation ("HS") epithermal gold system, including intense acid
leaching, strong structural and lithological permeability controls to
fracture fed mineralizing fluids, presence of structurally-controlled
hydrothermal and phreatic breccias, disseminated mineralization of
gold-silver much greater than copper, and the elemental association of
As, Sb, Bi, Ba, S and Te.
The Miwah Property is in a very similar volcanic setting to the Martabe
gold-silver deposit, also located in North Sumatra (Purnama and Baskara
resources: 127.8 million tonnes at 1.4 g/t gold (5.5 million ounces
gold) and 15 g/t silver (60 million ounces silver), and the alteration
system is of a comparable size. In addition to similarities to Martabe,
the Miwah project also exhibits a likeness to the size, style and
geometry of the alteration system developed at another important HS
gold deposit, the Pierina gold deposit in Peru (67.7 Mt grading 2.98
g/t gold and 22 g/t silver, giving a total 6.49 million ounces gold and
47.9 million ounces silver).
Miwah was partially defined by approximately 3000 metres of drilling in
eleven holes by a previous explorer in 1997. All holes drilled during
this program intersected significant alteration and mineralization with
intercepts including 71 metres of 1.4 g/t gold and 58 metres of 1.1 g/t
gold. The previous explorer suggested potential for 100 Mt at 1.1 to
1.2 g/t gold, however a review of the historical data indicates that
early drilling was clearly parallel to higher grade (greater than 5 g/t
gold) structures at surface, and hence significantly higher overall
grades are anticipated from better oriented drill holes. The total
2,316 rock saw channel samples collected by EAS in 2008 averaged +1 g/t
gold and +3 g/t silver and the Company believes that this underlines
the huge, world-class potential of this high sulphidation gold system.
Samples reported were assayed at Intertech assay laboratories in
Jakarta. David Royle, B.Sc. (Hons), FAusIMM, CP, the designated QP
within the meaning of 43-101, has reviewed and approves the content of
this release. East Asia has not verified the classification of the
resource references and is not treating them as NI 43-101 defined
resources verified by a QP. Although the references of resources are
relevant to recognizing the potential of the Miwah project, they should
not be relied upon.
