The company launched a prospectus, offering a minimum of 10 million shares at 20c per share to raise at least $2 million.
Oversubscriptions for up to a further 20 million shares to raise a total of $6 million will be accepted.
Tian Poh has 10 projects in Mongolia spanning 125,000 hectares.
The most advanced is the Huabei Kuangye coking coal deposit, which has a 30-year mining licence, and is located adjacent to Gobi Coal & Energy’s Shinejinst coking coal mine.
The company also has projects prospective for copper and gold.
Tian Poh was formed by Singaporean entrepreneur Poh Kay Ping, which founded investment company POH Group.
“Tian Poh has a high quality portfolio of mineral assets, located on the doorstep of the world's biggest consumer in China, and near to planned or existing infrastructure,” he said.
"Our strategy is to generate early cashflow through bringing Huabei Kuangye to production, so as to fund advancement of our other coal, gold and copper assets.
"We believe the timing for new shareholders is favourable given Mongolia's shift towards attracting and maintaining foreign investment and its pro-mining initiatives.
“We are focused on building the next diversified resources company in Mongolia and believe that our clear pathway to early production, in-country management team, and pipeline of exciting and highly prospective assets will set the company up for prolonged growth going forward."
The IPO is set to close on September 15.
