Highfield Resources (ASX:HFR) said it received regulatory approvals from Australia's Foreign Investment Review Board for the stakes in the firm that Yankuang Energy Group and Beijing Energy International plan to acquire as part of binding agreements to create a diversified potash firm, according to a Tuesday Australian bourse filing.

It also received no notice under applicable sections of the Investment Canada Act, satisfying a clearance condition to acquire Yancoal Canada Resources under the agreements.

The regulatory review decision under the Spanish foreign direct investment laws is expected in due course and it is working with authorities in Spain to resolve the Goyo permit administrative matter, per the filing.

It confirmed that its senior secured project finance facility will be amended so that Societe Generale, BNP Paribas, and Natixis will exit the facility. It is working with its financial advisor, DBS Securities, the continuing lenders ING, HSBC, and Caja Rural, as well as with potential lenders to replace lenders exiting the facility.

It is also renegotiating an equipment operating lease facility with Macquarie Specialised Asset Services, which originally amounted to 25 million euros and which recently expired.
