Asia Pacific expands Thai potash potential

Reconnaissance exploration north of the Somboon potash field in Thailand indicates the presence of a new deposit for Asia Pacific Resources (TSE).

The company reports that three new sylvinite zones have been identified in the reconnaissance area, known as the Udon field. The combined zones cover an area measuring some 35 to 40 sq. km, and the potash thickness is estimated at 12 metres.

Drill results are pending, but Asia Pacific reports that grades appear similar to those of the Somboon field. Additional seismic programs are now under way to assess the potential of the property and will be followed up with 10-12 exploration holes.

In addition, the company is conducting feasibility work on the Somboon field for a 2-million-tonne-per-year potash mine. Preliminary estimates for the Somboon field put the minable reserve at 160 million tonnes over an average thickness of 4.1 metres. The sylvinite grade for the reserve is estimated at 25.5% K2O.

Asia Pacific has a 60% interest in the project, whereas Thai Central Chemical holds the rights to 30%. The Thai government retains the balance.
