TORONTO, ONTARIO--(Marketwire - Oct. 30, 2012) - Southeast Asia Mining Corp. ("SEA" or the "Company") is pleased to announce that it has received a resource estimate of 2,895,500 tonnes Indicated and 1,955,000 tonnes Inferred for the Boh Yai and Song Toh historical operating mines in Thailand. The NI 43-101 compliant mineral resource was estimated by ACA Howe International Limited ("ACA Howe") using historical diamond drilling results that were verified by analyses of stored core and pulp samples.

A copy of the NI 43-101 Technical Report will be filed on SEDAR within 45 days of this news release. The mineral resources were estimated by Rick Parker, FGS, MIMMM C. Eng., Consulting Geologist with ACA Howe. Mr. Parker is a Qualified Person for the purposes of National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators, and has verified the data disclosed in this release.

The mineral resource is based on approximately 58,100 meters of historical diamond drilling at the Boh Yai and Song Toh mines. The mines were originally discovered by Cominco in 1948 and explored and operated by the German mining company Metalgesellschaft from 1969 to 1991 and subsequently by a private Thailand company Kemco until 2002 when they were closed due to depressed metal prices. Historically the mines processed approximately 5.4 million tonnes of ore at the 1,200 tpd flotation plant. The plant was refurbished in 2008 by SEA and its joint venture partner when approximately 60,000 tonnes of ore were processed. Historical exploration at the mines was limited during operations and the exploration potential within the mines along strike and to depth and the surrounding properties is considered excellent.

Brian Jennings CEO of SEA commented, "It is very exciting to establish a NI 43-101 compliant resource based on the historical mine data which substantiates the mining records and confirms the future operating potential. SEA is a private company planning to go public and recommence production at Song Toh and Boh Yai and conduct a modern day exploration program on the properties surrounding the historical mines. The resource estimate and the recently announced amended joint venture agreement are significant corporate accomplishments which support a listing of our shares on a recognized stock exchange and the mine permitting process."

The mineral resource block model estimates are outlined in the table below.

Notes:



a. Mineral resources which are not mineral reserves do not have
demonstrated economic viability. The estimate of mineral resources may
be materially affected by environmental, permitting, legal, title,
taxation, socio-political, marketing, or other relevant issues.
b. The database used by ACA Howe for the resource estimate contains 3,914
Pb, Zn and Ag assay results from 551 surface and underground diamond
drill holes (total of 58,078 metres). Samples were assayed historically
by the mine laboratory at Song Toh with check samples by SGS. A
representative number of core and pulp samples that were analysed in
2012 by ALS provided verification of the historical assays.
c. Lead Equivalent - Pbeq - was calculated using prices of US$0.93/lb lead,
US$0.90/lb zinc, and US$ 23.03/oz silver, (with no provision for
metallurgical recoveries). The formula used was Pbeq% = Pb% + 0.962Zn
(%) + 0.0360Ag (g/t). Small discrepancies may exist due to rounding
errors.
d. Mineralised domains were modelled with the aid of drill results and
detailed interpretations of geology recorded on historical plans. A
total of 42 individual domains was identified, including 28 at the Boh
Yai deposit 9 at the Song Toh SW deposit and 5 at the Song Toh Camp
deposit.
e. Micromine block models with block cell dimensions of 4.0 metres and sub
blocks of 2.0 metres were coded to reflect surface topography and
geology. Metal values from 1.0 metre drill composites were interpolated
to block models using Inverse Distance Squared weighting (IDW2)
according to parameters and search ellipsoids established from analysis
of the variography within each domain. A three-pass approach was used to
interpolate metal into the blocks. A density factor of 2.9 t/m3 was
assigned to all mineralized domains based on historical measurements of
specific gravity. For resource classification, 2 drill holes with 3
composites and a search distance less than the range were required for
Indicated category, remaining blocks were assigned to Inferred category.
