MAE CHEDI PROJECT

The Mae Chedi property is located northeast of Chiang Mai, close to the main highway connecting Chiang Mai with Chiang Rai. A tungsten ore (scheelite), associated with tin (cassiterite) occurs in quartz veins and stockworks in granitic rock and in the contact zone between these and carboniferous mafic intrusives. The ore is also disseminated in both the granites and in the mafic intrusives.

The Mae Chedi mine operated as a ‘gravel pump’ (hydraulic) mine during the 1970s, producing a tin/tungsten concentrate. Contrary to common practice during these years, the mine owners 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.

Amanta initiated a rock and soil sampling programme (on a 500m x 500m grid) to confirm these anomalous values. Results showed large areas underlain by rocks with anomalous tungsten and tin values, including a very extensive area anomalous in tin (with assay values of up 1.5% tin) and a smaller anomalous tungsten area with assay values of up to 7% WO₃. Further detailed work would be required to define any mineable resource.

With Amanta’s focus on becoming a significant copper/silver and molybdenum exploration company in Laos, the Company’s Thai projects are no longer considered core projects and Amanta is considering ways to realise the value of its Thai assets, either through Joint Ventures or sales.
