Speaking at the 2009 Diggers & Dealers forum earlier this week, St Barbara managing director and chief executive officer Tim Lehany said the investment was under review as part of its strategy to divest non-core assets.
St Barbara had previously written down its investment in Bendigo to $7.2 million on a mark-to-market basis at the end of 2008.
The company expects to post a profit before tax on the sale of around $2.7 million this financial year.
At the end of June, St Barbara had cash of $78 million.
Small-scale miner Bendigo operates the Kangaroo Flat mine in Victoria and recently acquired the Henty mine in Tasmania from Barrick Gold Corporation.
