PANDS | History | Nature of Business | Our Companies | Vision

As the world’s economy was leaping in 1962, so was the natural gas and oil drilling industry. During that time, Mr. Choosak Smitasiri, the founder of Pands Group Co., Ltd., was also pioneering lead, tin, and antimony mine. As a creative thinker and incomparable leader, he wanted to start a never-before business by exploring the new kind of ore in Thailand and found that barite was another ore important to the economy, especially in the natural gas and oil drilling industry.

Consequently, Mr. Choosak was the first one in the country to start the barite mining business. The company had a lot of foreign clients, one of which was Dresser Industries Corporation, America’s forefront natural gas and oil drilling organization. Mr. Choosak decided to expand the scope of business and became the first barite exporter in Thailand.

The company’s reputation is recognized by both local and international firms, leading in the natural gas and oil drilling industry, such as Unocal (Thailand), Esso (Thailand), Shell (Brunei), Chevron (Thailand) Exploration and Production, and Halliburton. P&S Barite Mining Co., Ltd. is now accredited as the country’s biggest barite mining company.

Over forty years, the company has been growing and continuing to explore other fields of business, including milling factories, jetties, and logistics, united under the name of “Pands Group”, of which production and service bases are located all over the country. Our management system holds to the Good Governance principle. According to the founder’s policy and the firm basis he built, we are determined to be the enduring leader in the mining business.
