Mt Gunyan is located approximately 4.5km north-east of the Twin Hills Mine and is a mesothermal disseminated silver deposit, with elevated gold in some parts. There is the potential for massive sulphide mineralisation at depth as evidenced by elevated lead on the hanging wall and elevated zinc on the footwall of the deposit.
The Mount Gunyan deposit is considered the next source of ore feed for the heap leach mining operation at Twin Hills.
Alcyone has defined a current heap leach silver resource for the Mount Gunyan deposit of 2.3 million tonnes grading 69g/t Ag for 5.19 million ounces of silver. Click here to see full JORC Resource.
Work is progressing on the preliminary Feasibility Study for development of the Mt Gunyan deposit. Samples from the existing core have been dispatched for metallurgical testwork on the extraction of silver mineralisation.
Once the metallurgical parameters are more accurately defined, the next phase of mine planning and permitting will be commenced.
