And company chairman Jasbir Singh has announced he will leave the company completely, less than two weeks after telling the shareholders he would remain on the board as a non-executive chairman. He quit  as chief executive in May.

On Monday the ASX announced Wollongong Coal had been suspended from quotation after failing to lodge a report in line with the ASX’s listing rules. Its shares have not been traded since.

The company had failed to file its preliminary final report for the period ended March 31, 2015.

These were the latest setbacks for a company which had seemingly lurched from crisis to crisis for several years.

Mr Singh, Indian steel mogul Naveen Jindal’s man in Australia, resigned from his position as chief executive on May 11 but committed to stay on as a non-executive director and chairman of the board.

Just 11 days later the company announced to the ASX that Mr Singh had resigned from the board completely. No reasons were given.

He has been replaced by a man called Azad Bhura, as the new nominee of Jindal Steel and Power Mauritius, the controlling shareholder of Wollongong Coal. The company said he was a chartered accountant  ‘‘associated with’’ the Jindal Group since 2004.

The Mercury has asked the miner why Mr Singh resigned, why the report was not filed, and whether the events were related, but we did not receive a response by deadline.

The company has had trouble with its financial reports before. A year ago Wollongong Coal’s auditor, Grant Thornton Chartered Accountants, criticised the company for its reporting of what it called ‘‘doubtful debts’’.

And when assessing the previous year’s annual report, the same auditor said there was not enough information for it to vouch for the company’s financial position.

Government agencies have also declined over years to approve the mine’s expansion plans, saying the company had not provided sufficient evidence for environmental assessments.

It has meant continuing uncertainty for the estimated 186 people employed at the colliery.

Wollongong Coal had slashed another 41 jobs from its Russell Vale operations in mid-May, calling the cuts a ‘‘restructure’’. This included 13 voluntary and 28 forced redundancies.

At the time Mr Stone said this was a direct consequence of not having approval to continue mining past the current 356metres of Longwall 6.

Before the suspension, shares in Wollongong Coal have hovered around the 2c mark for some months, apart from a dip down to 1.4c in late May which was followed by a rally back to 2c mark.

The company has been approached for comment.
