Misima was operated as an open-pit gold mine from 1989 to 2001, with stockpiled ore treated for the final three years of the operation until 2004.
The operator mined 87.5 million tonnes at 1.46 g/t gold producing 3.7 million ounces of gold and 22 million ounces of silver.
Gold recoveries averaged 91.5% and costs averaged US$218 per ounce.
At the time the decision was made to close the mine, the gold price was below US$300 per ounce.
Focused on three key areas
In November 2017, Kingston revealed a 2.8 million ounces JORC resource grading 1.1 g/t gold across two deposits Umuna and Ewatinona.
Kingston commenced drilling in May 2018, which was the first exploration drilling for gold on Misima in almost 20 years.
The aim is to increase the resource inventory to over 3.0 million ounces with the key targets being Misima North, Umuna East and Quartz Mountain (Ewatinona and Abi).

- Review Umuna resource/reserve opportunities
- Review Kulumalia geology and model
- Maintain 2 drill rigs testing a portfolio of resource definition and advanced targets into 2020
- Ewatinona and other mineral resource models H1 2020
- Mining studies to commence from mid-2020
