Kochang contains gold and silver

Bluebird Merchant Ventures (LON:BMV) is happy with initial recovery levels of gold and silver in samples taken from the Kochang Mine in Korea.

Using a simple gravity separation process, recoveries of 80% of the gold and 60% of the silver from a composite sample were recorded.

Grades in the sample were almost 5 g/t gold and 19 g/t silver, which was similar to results obtained underground.

The initial metallurgy work showed the ore is not problematic and does not require complicated or expensive extraction techniques.

Bluebird said the ore will now be tested using a more complex leach process, which should boost the amount of metal recovered.

Colin Patterson, chief executive, said:The initial test work has demonstrated higher than the industry standard in terms of recovered gold for this simple and inexpensive gravity process.

“This will certainly improve the economics of production following the reopening of the Kochang mine.

 “As I have consistently said, the economics of reopening an old mine is far less costly than that of new development."
