Discussion and Analysis also flagged a net loss of $32,877,579 for the nine month period ended September 30.
The company said it had determined there were indicators of impairment for its exploration and evaluation assets and property, plant and equipment.
"The indicators of impairment result from the current economic uncertainty in general and the downturn in the mining industry in particular, decline in the company's market capitalisation and the company's decision to significantly reduce future exploration expenditures until the economy improves," PNG Gold said in a statement.
"As a result, the company recorded impairment losses for the three and nine months ended September 30, 2013. All of the impairment loss relate to assets held in Papua New Guinea.
"The company's exploration and evaluation assets are currently at the exploration stage and there have been no resources established to reliably estimate the economic viability or future cash flows of the properties."
