CAIJIAYING EXPANSION & COMMISSIONING OF PROCESSING FACILITIES

Griffin Mining Limited ("Griffin") is pleased to report that commissioning of the significantly  refurbished and upgraded processing facilities at the Caijiaying mine commenced this morning following the suspension of processing announced on 13th August 2014.  The refurbished two 350,000 tonnes per annum primary ball mills, new and larger floatation cells and increased storage and handling facilities were commissioned using the crushed ore available.  The new, three stage rushing circuit and back-up generators are expected to be commissioned on Wednesday 19th November with ore that has continued to be mined and stockpiled for the past 3 months.  Name-plate throughput of 750,000+ tonnes per annum should be re-instated at this point.

The upgrade to the main processing facilities is scheduled to be completed on December 15 upon the delivery and installation of the new, 800,000 tonnes per annum primary ball mill.  It is hoped that demarcation issues between competing Chinese power suppliers for an enhanced power supply to the processing facilities will be resolved by that time.  It is expected that throughput will reach 1.5 million tonnes per annum by the summer of 2015.

The upgrade continues to fall within the capital amount budgeted, however, due to the 4 week delay in commissioning, annual production of zinc metal in concentrate for 2014 is expected to be lower than that achieved in 2013.
