AIM-listed GoldStone Resources reports it is sinking a new shaft to access the historic high-grade Akrokeri underground gold mine, one of two previously producing operations at its Akrokeri-Homase Gold Project (AKHM) in the Ashanti Region of Ghana, to enable it to complete a geological assessment of the mine.

The Akrokeri mine is located approximately 6 km along strike from one of the world's major gold mines, AngloGold Ashanti’s Obuasi mine.

Goldstone sinks shaft to access historic mine

The shaft is intended to provide access to the mineralised zone at the mine, which produced 75 000 ounces of gold in the early 1900s at a recovered average grade of 24 g/t Au. It will also allow access to the old mine workings, which were fully operational until an ingress of water in 1909. In addition, it will provide geological information and allow the extraction of samples for test work.

Timber sets are being installed in the side walls of the 3 by 3 m shaft as the sinking progresses and the shaft is being partitioned to create three compartments, the manway compartment, the services compartment and the hoisting compartment.  

Once the shaft is at its target depth of 30 m depth below surface, a cross-cut will be developed to gain access to the historic mineralised area whilst, at the same time, Goldstone will probe for any old workings/voids that may allow the safe access to the old mine workings.

The Norton Shaft is being sunk approximately 40 m to the east of the existing North Shaft that is now derelict. Work at the old North Shaft is currently under way to ascertain if this shaft can be re-opened for use by Goldstone. Depending on the state of the shaft, it may be utilised as a second point of egress, for ventilation purposes and also to gain access to the old underground mine workings.
