The Canadian company has now acquired 100% interests in three former tungsten mines: Mae Chedi, Mae Lama and Doi Ngom. These properties hosted some of Thailand's high grade tungsten mines prior to the collapse of world tungsten prices in the mid-1980s, which forced the closure of many tungsten producers.

The Mae Chedi property is located northeast of Chiang Mai, close to the main highway connecting Chiang Mai with Chiang Rai. Mae Chedi was operated as a hydraulic mine during the 1970s, producing a tungsten/tin concentrate. According to Amanta, the former owners—contrary to common practice during these years— completed a rock sampling survey over much of the mine area. The results of this survey indicated an extended anomalous zone covering up to 30 hectares, over which combined tungsten/tin values of 0.3% were measured.

The company said further detailed work will be required to define any mineable resource and Amanta is planning to begin extensive exploration activities, including an initial drilling program, early in 2008. Amanta also is currently evaluating the economic potential of Mae Lama and Doi Ngom.
