China Rare Earth (HKG:0769) said an independent forensic firm hired by the company to investigate complaints over the purchase of tungsten bars cleared the company of any wrongdoing, according to a Hong Kong bourse filing Monday.

Shares of the company remain suspended from trading.

Acclime Corporate Advisory (Hong Kong) began probing the matter following complaints from former directors and employees over the purchase of tungsten bars from a new substantial shareholder.

The investigator concluded that the purchase complied with necessary regulation and by-laws and the complaint lacked merit.

As a result, China Rare Earth no remedial actions were necessary.
