Cambodia: Kampong Son Bay, SiO2 content 99.3%, wide distribution, will be surveyed.
Thailand: There are high-grade silica sand deposits along the coastline in Chanthaburi, with an annual output of 60,000 tons. Rayong is the largest silica sand production area in Thailand, with an annual output of about 400,000 tons. In addition, there are two silica sand production areas. Temporary suspension of production due to tourism development.
