Thailand has not been a prime destination for gold explorers, but Amanta Resources (AMH-V, AMHFF-O) should soon be ready to drill its Langu gold prospect in Satun province, on the Thai part of the Malay Peninsula.
Amanta plans to follow up surface prospecting activity with a 5,000-metre drill program as soon as a drill can be sent to the project. The 25-sq.-km property hosts a 6-km-long trend of surface gold showings, outlined by geochemical surveys on soils and rocks, along a north-running ridge of silicified shales and limestones. The setting led company geologists to believe the area is prospective for Carlin-type replacement gold deposits.
Amanta’s early prospecting uncovered high gold values in samples from workings in an old antimony mine. That led to the surface geochemical work, which provided six target areas.
Backhoe trenches, about 2 metres deep, exposed bedrock only on some targets; the local overburden is very deep. Gold-mineralized rock is mainly silicified and pyritic mudstone, with gold grades of 1.8 grams per tonne over 21 metres at one prospect, May, and 8.8 grams per tonne over 7 metres at another, Discovery South. A third prospect, Banhan, returned grades of 0.3 to 0.6 gram gold per tonne over “tens of metres,” the company reported.
An induced-polarization (IP) survey, initially using a gradient array to allow for fast surveying, defined northwest-to-southeast zones of high chargeability and high resistivity. More IP surveys are planned using a slower, but more detailed, pole-dipole array. The company also plans an airborne magnetic survey.
