MAPUTO, Nov 8 (Reuters) - Mozambique's finance minister has a plan to deal with a debt crisis that threatens to derail one of Africa's most promising frontier economies but investors are far from convinced.

Adriano Maleiane told money managers in Maputo last week an independent audit should bring transparency to billions of dollars of secret debts while negotiations with creditors would calm financial markets and bring the International Monetary Fund (IMF) and Western donors back to the table.

However, in interviews, bond-holders, energy executives, Western diplomats and political analysts expected Mozambique's crisis will run deeper and longer than Maleiane says as debt talks hit hurdles and a planned gas boom is delayed.

"There will be no quick fix," one banker, who holds Mozambique government debt, told Reuters. "There is a lot to iron out and we need evidence of long-term stability before restructuring," added the banker, who spoke on condition of anonymity.

President Filipe Nyusi's government last week appointed risk management firm Kroll to conduct an audit into secret loans, a condition for the IMF to resume aid talks with this war-scarred southeast African nation. The Mozambique government said earlier this year it arranged sovereign borrowing without parliamentary approval, as required by law.

Maleiane said he does not think the audit will uncover any more secret loans, but left the door open by asking anyone who knew about extra debt to come forward.

"That doesn't fill me with confidence," said another bond- holder who declined to be identified because of the sensitivity of the issue. "If the finance minister doesn't know, who does?"

Maleiane wants to renegotiate some of the government's $11.2 billion in debt with creditors by January but Western donors, the IMF, international banks and hedge funds will all want the best deal and for the other parties to commit first.

"Who wants to blink first?" Stuart Culverhouse, an analyst at Exotix investment bank, said, adding: "Comprehensive debt restructuring could take a long time and potentially get messy while the audit may reveal more skeletons. The government's timeline is extremely ambitious."

GAS SEEN AS SAVIOUR

Until recently one of Africa's brightest prospects, Mozambique is facing its biggest economic crisis since a 16-year civil war ended in 1992 after evidence of more than $2 billion in secret loans emerged earlier this year.
