UPDATE 1-SACMH mulls sale of mine to save ops -CEO

* Considering sale of mine

* Involved in several negotiations

* Share falls after says could sell mine

(Adds detail)

JOHANNESBURG, April 20 (Reuters) - Junior minor South African Coal Mining Holdings (SACMH) (SAHJ.J) sees the sale of its mine as one option to make the firms' operations profitable, Chief Executive Grant Scrutton told Reuters on Monday.

The company, which has been negotiating with state-owned utility Eskom [ESCJ.UL] to supply it with 40,000 tonnes of coal per month, last month halted operations for up to three months due to falling coal prices and difficult trading conditions.

Shares in the firm lost more than half of its value as a result, and traded 2.3 percent lower after news that it was considering the sale of its mine.

"We have suspended operations for a maximum of three months to revaluate the business model and make one that is more sustainable. A whole bunch of alternatives are incorporated into that thinking ... anything is on the table," he said.

Asked whether selling the company's mine was part of the discussions, Scrutton said: "If anything is on the table, anything is on the table ... we are involved in several negotiations," he said, but declined to give any more details.

SACMH is a South African coal producer with an annual allocation to export 207,000 tonnes of coal through the Richards Bay Coal Terminal (RBCT).

That allowance will be raised to 707,000 tonnes per year after the port's expansion due to be completed by July.

A possible sale of the export allocation is also part of the ongoing discussions, Scrutton said.

Before putting its operations on hold, SACMH was seeking to up output to 150,000 tonnes per month from 80,000 tonnes.
