VANCOUVER, BRITISH COLUMBIA--(Marketwire -
March 2, 2010) - East
Asia Minerals Corporation (TSX VENTURE:EAS) announces that drilling continues to expand the
strong gold mineralization at the Miwah Main Zone in Aceh Province, Northern
Sumatra, Indonesia. Assays have been received for the remaining portion of the
upper mineralized interval in EMD018, and for all of EMD020. The upper
mineralized interval in EMD018 encountered 2.18 g/t gold over 116 metres,
including 3.28 g/t gold over 61 metres; followed by a secondary zone of
intermittent massive/vuggy silica and alunite alteration (assays pending).
EMD020 encountered 2.12 g/t gold over 108.2 metres, including 3.34 g/t gold
over 46.7 metres. This drilling has extended the gold zone further to the north
where it remains open. East Asia has validated the 1.2 kilometre east-west
width of the shallow, laterally extensive Main Miwah Gold Zone, and has
encountered gold mineralization in all of its holes. The Main Miwah Gold Zone
remains open in all directions with the Moon River area expanding the
north-south potential from 400 metres to more than 600 metres, whilst remaining
open further to the north towards Sipopok.
EMD018 was drilled with a due north azimuth
and 30 degree dip to test the area north of EMD001/002/003 where 1.71 g/t gold
over 158.0 metres, including 3.29 g/t gold over 66.0 metres; and 2.25 g/t gold
over 142.9 metres, including 4.31 g/t gold over 51.0 metres were encountered by
the Phase One drill campaign. The hole was completed at 304 metres downhole
depth and extended the favourable silica alteration 260 metres to the north of
EMD001/002/003 where it remains open. Gold grading 2.18 g/t was encountered
from 39 to 155 metres downhole depth, including 3.28 g/t gold from 39 to 100
metres (39 to 86 metres reported February 17, 2010). Of added
significance is that the main mineralized body is underlain by a newly
recognized secondary zone of intermittent massive/vuggy silica and alunite
alteration from 215.5 to 299.5 metres. This is interpreted to represent a
stratiform layer underlying the laterally extensive Main Miwah Gold Zone.
Assays for 161 to 304 metres are pending and further work will determine the
potential upside of this gold mineralization. The mineralization in EMD018 is
open in all directions and at depth, and is interpreted to be contiguous to the
southwest towards EMD003, to the northeast towards EMD017, and north past
EMD019.
EMD019 (reported February 17, 2010)
encountered 4.08 g/t from 82 to 163 metres downhole depth, including 9.29 g/t
gold from 90 to 111 metres. This hole was drilled in a south direction to test
the area from 155 metres north of EMD001/002/003/018. The mineralization is
open in all directions and at depth, and is interpreted to be contiguous to the
southwest towards EMD003, to the northeast towards EMD017, and south past
EMD018.
EMD20 was drilled with a 205 degree azimuth
and 50 degree dip to test the area west of EMD019, and finished at 200 metres
downhole depth. Gold grading 2.12 g/t was encountered from 77.3 to 185.5 metres,
including 3.34 g/t gold from 77.3 to 124.0 metres. The gold is open to depth
and is interpreted to be contiguous in all directions towards recently
completed holes, all of which are mineralized.
Michael Hawkins, President and CEO of East
Asia Minerals Corporation stated "The intersection of strong and consistent
gold mineralization in EMD018 and 020 again demonstrates the veracity of the
exploration model we have developed for the Miwah Main Zone. The discovery of
an underlying massive/vuggy silica and alunite alteration layer in EMD018 opens
an added dimension and solidifies the growing importance of this play. Drilling
of the Miwah system continues to reveal that it has the potential to be one of
the more important gold discoveries in this exploration cycle and at a time
when finding large gold deposits is rare."
EMD021 was drilled with a 250 degree
azimuth and 50 degree dip to test the vuggy silica alteration northwest of
EMD020, and finished at 200 metres downhole depth. The hole encountered visually
altered and mineralized rock from 52 to 127 metres, followed by intermittent
but predominantly vuggy/massive silica and silica/alunite alteration to the end
of hole. Assays are pending.
EMD022 is progressing with a 190 degree
azimuth and 70 degree dip to test the area immediately south of
EMD001/002/003/018. The hole entered visually altered and mineralized rock at
5.7 metres depth. Surface rock sampling in this area gave 9.22 g/t gold over 14
metres, 6.62 g/t gold over 6 metres, and 2.5 g/t gold over 24 metres.
EMD023 has commenced with a due north
azimuth and 50 degree dip to test the extension north from the high-grade gold
mineralization encountered by EMD018 and EMD019, as well as testing the
recently discovered underlying massive/vuggy silica layer in EMD018. (Refer

Miwah Background
The Miwah Gold
Prospect was partially defined by approximately 3,100 metres of drilling in
twelve 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 parallel to
higher grade (greater than 5 g/t gold) structures at surface. Hence, in
addition to greater mineralized tonnage, significantly higher overall grades
are anticipated from better geological understanding, results of the Company's
detailed sampling, and properly oriented drill holes.
Based on the Company's work Miwah is resolving into
two components; a large 1,200 metre long, at least 300 to 400 metre wide,
approximately 200 metre thick tabular zone; and vertical diatreme breccia
feeder zones that are beneath and cut through this. At Miwah Gold Zones, East
Asia has almost 2,500 metres of rock sawn channel samples which average 2.35
g/t gold. Grade expectations in Main Miwah Gold Zone exceed 1.5 g/t gold.
Ongoing sampling verified the Company's confidence that higher overall gold
grades can be achieved due to the presence of multiple high grade rock sawn
channel samples throughout the strike, including 4.11 g/t gold over 200 metres
at the eastern part of the Main Miwah Gold Zone, and 4.35 g/t gold over 27
metres at the western part. Recent drilling has supported this. In addition to
the tabular zone the Company has begun to characterize some of the diatreme
breccia feeder zones, with rock sawn channel samples including 83.59 g/t gold over 24 metres and 20.14 g/t
gold over 12 metres. Recent drilling has supported this. These feeder zones have great potential to develop into substantial
tonnages of higher grade gold mineralization in an area adjacent to the Main
Miwah Gold Zone.
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.
Miwah also exhibits a likeness to the size, style and geometry of the
alteration system developed at 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).
Samples reported were assayed at Intertek
assay laboratories in Jakarta. Lionel Martin, P.Geo., the designated QP within
the meaning of NI 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.
