Southeast Asia Mining Commences Drilling in Thailand

TORONTO, ONTARIO--(Marketwire - Feb. 24, 2011) - Southeast Asia Mining Corp. ("SEA" or the "Company") is pleased to announce that exploration work has re-commenced on the Company's Special Prospecting Licences ("SPLs") in Thailand which are held by SEA's operating subsidiary, Geotai Exploration and Mining Co., Ltd. ("Geotai"). The exploration period has been granted for five years on all Geotai SPL's, with the main objective to define mineral reserves of molybdenum, lead, zinc and copper. GMT Corporation Ltd. has been contracted to assist with the program planning, field supervision, core logging and sampling and data compilation and analysis. 

Geotai Managing Director Geoff McIntyre was present for the commencement of drilling in Chanthaburi Province, on SPL 2/2551, where the Company has begun conducting diamond drilling on the first of three target areas of anomalous zones at depths of 80 to 120 metres as follow up work on surface exploration to define geochemical anomalous zones of molybdenum, lead, zinc and copper. There are two zones of geophysical anomalies, the first zone is trending NE-SW about 700 metres wide and 1,400 metres in length and the second zone trending NE-SW about 50 metres wide and 850 metres long. The anomalies are hosted in grey, coarse grained biotite granite, quartz veinlets about 1 cm to 15 cm thick trending approximately E-W/90 direction.

On SPL 19/2551, also in Chanthaburi Province, the Company has completed conducting surface geological mapping and geochemical soil surveying along assigned survey lines. According to previous work, soil geochemical surveys show geochemical anomalies of molybdenum, lead, antimony, zinc and copper. The area is underlain by grey subarkosic sandstone, mudstone and conglomerate of Ck1 rock unit of Triassic age. Properties containing high levels of molybdenum and antimony have been found in this area and mined.

In Kanchanaburi Province, on SPL's 2/2552-5/2552, the Company has begun conducting preliminary surface geological surveying including Landsat interpretation, airborne geophysical interpretation, surface geological mapping, geochemical surveying and chemical analysis. The SPL's are located closely to the lead-zinc mines of KEMCO Ltd. The ore is combined lead-zinc with silver credits. The deposit has been defined as "strata-bound massive sulphide deposit" and mineralization has been defined within Ordovician limestone similar to the Mississippi Valley in US. Structurally, the rock has been folded to a synclinal form with the fold axis plunged to the SE direction. The area has been bounded on both sides by the NW-SE faults/fractures. On the eastern part, a fault contact between Ordovician limestone and Triassic rocks is presented.

Kerry Smith, President, CEO and Director of the Company stated,

"We are excited to be conducting exploration in early 2011. The Chanthaburi molybdenum site has the potential to be a major asset in the SEA portfolio. The Kanchanaburi SPLs are located in an area with historical lead-zinc deposits and warrant serious exploration." 

Southeast Asia is a junior exploration and mining company operating in Thailand and Southeast Asia. Its main asset is a majority ownership in a former base metal producer which, in conjunction with its Thai partner, is in the process of renewing the mining licenses. The Company also has seven special prospecting licenses in various stages of exploration.
