Multiple access points located by development partner Bluebird Merchant Ventures at Gubong, South Korea
- Several underground access points (adits) located at Gubong by LSE listed Bluebird Merchant Ventures Ltd
- One of the main access points at “Korean Main Adit” has been opened from above to test quantity and quality of retained water
- Dewatering and physical access to commence shortly
Important Milestone Reached by our Development Partners
Australian gold producer, Southern Gold, is pleased to advise that its wholly-owned subsidiary, Southern Gold Korea (SGK) has received notification from development partner, London Stock Exchange-listed Bluebird Merchant Ventures Ltd (‘Bluebird’), that it has made good progress in locating historical access points at the Gubong Gold Project in South Korea. This work has been conducted under the farm-in phase of the Farm-In and Joint Venture Agreement signed with Bluebird in March this year (see ASX Release 27 March 2017).
The location of access points has been done by combination of referral to historical maps, the use of ground penetrating radar and advice from local community members, some of whom worked at the mine in the 1960’s.
Photos 1 and 2 below are of the main Decline Shaft.
Bluebird has advised that in addition to the Decline Shaft, access points have also been located at Korean Main Adit #2, Adit #3 and Adit #4 (Figure 1). Early indications are that some effort has been made to close off the mine with rubble or soil fill that will require excavation. Bluebird does not anticipate this being a significant impediment to progress

Bluebird is taking a careful approach to the management of retained water inside the blocked adits. The water will be tested and then ultimately pumped out enabling the removal of the rubble blocking the entrances. The water detected in the Korean Main Adit is not under pressure and appears at this stage to be relatively benign. Because this section of the mine is above the water table it is expected to be a simple process to dewater and gain underground access from this point.
Once underground access has been gained, ground conditions will be studied carefully and survey work completed to establish a good baseline for future work. In due course the Bluebird team will begin mapping and sampling the dry areas of the mine to establish the extent of remnant ore available either in partially completed development or left behind by previous workers.
Figure 2 illustrates the multi-kilometer scale of the mine and the significant amount of underground mine workings. Bluebird and Southern Gold believe there is a significant dollar value embedded in these extensive workings and provides the development partners with the opportunity to advance the project forward much more rapidly than would conventionally be the case with a Greenfield development.
It is expected that, given the much lower gold prices prevailing at the time of mine closure, that much of what was not considered ore during that period will be economic today but much work remains to be done to quantify and confirm this.
Southern Gold Managing Director, Mr Simon Mitchell:
“Bluebird is making very good progress at the Gubong Gold Project in South Korea. In what has been trying operating conditions with significant rainfall and having to work from old historical references, the Bluebird team have shown great perseverance and been rewarded by locating multiple access points into the mine. I have also been impressed with the professional way they have gone about their business and in particular being careful with retained water management and close engagement of the community.
Hats off also to our local Southern Gold Korea team who have been instrumental in establishing excellent relations with the county government and local community. This sort of work is always critical and will hold us in good stead for the long term progress of the project.
Once Bluebird get underground I think it will astound investors and analysts alike as to the scale of what we are dealing with at Gubong and the potential for a significant mining operation will start to become obvious. In the longer term we believe Gubong will evolve into a significant company building asset.”
