The Minerals Act, B.E. 2560 (2017) (the Act) will become effective on 29 August 2017, after 180 days from the promulgation in the Royal Gazette on 2 March 2017.

The key changes, as compared to the Minerals Act, B.E. 2510 (1967), as last amended in 2002, are summarized in the Client Alert "New Developments on Mining in Thailand Part 2", issued in February 2017.

All ministerial regulations, notifications, rules, or orders issued under the Minerals Act, B.E. 2510 (1967) and the Mineral Royalty Rates Act, B.E. 2509 (1966) which are effective before the date the Act comes into force, will continue to be effective to the extent that they are not contrary to nor inconsistent with the Act. The Act specifies that related regulations are to be issued within two years from the effective date.

Any application submitted before the effective date of the Act will also be deemed an application under the Act, and will be considered under the rules as specified in the Act. Furthermore, any prospecting license, mining lease, or license issued under the Minerals Act, B.E. 2510 (1967) before the effective date of the Act will be deemed issued under the Act and will be effective until it expires or is revoked. Lastly, any obligation under any agreement made with the Thai government by the Ministry of Industry and Department of Primary Industries and Mines before the effective date of the Act will remain effective until the expiration of that obligation.
