Sydney, Australia (ABN Newswire) - Kimberley Metals Limited (ASX:KBL) is pleased to report on progress for production start up at the Mineral Hill Mine, located 65 kilometres north of Condobolin in centralwestern New South Wales.

The Company has been engaged in refurbishing the processing plant at Mineral Hill, since August 2010 in preparation for a recommencement of production from the mine with first production targeted for mid-2011.

Kimberley's development plan for Mineral Hill contemplates the development of both the Parkers Hill underground copper-lead-zinc mine and the Pearse open-cut gold-silver mine. The Mineral Hill plant will have two process trains, allowing the treatment of gold-dominant ores through a carbon-in-leach (CIL) circuit and base metal ores through a flotation circuit. Work on the CIL circuit will start after commencement of copper concentrate production.

First production of copper concentrates from the Parkers Hill underground mine remains on-target. All regulatory and operating approvals are in place.

The Environmental Impact Statement (EIS) and development consent application for the Pearse Gold and Silver Project has been submitted to the Lachlan Shire Council and public coments have been sought. Project approvals are expected late September/October 2011.

Parkers Hill Underground Mine

Kimberley has appointed mining contractor Pybar to provide underground mining services at Parkers Hill with a formal contract pending.

Key works to date are:

- All ground support by bolting and meshing of the decline drive completed

- The development Jumbo and underground mine truck have been mobilised to site and are in full operation

- First mine drive development on 225mRL commenced 6 May 2011 and approximately 45 metres advance have been achieved. The development (185 metres )will provide fresh ventilation for stoping activities and multiple ore drive accesses.

- Pumping capability for increased dewatering has been established to access mine levels for exploration drilling below 180mRL

- A license to store explosives has been approved by WorkCover and the explosives magazine is fully operational

The following works remain to be completed prior to initial ore production, which is anticipated at midyear.

- Completion of minor ground support by bolting and meshing in selected ore drive accesses on 180mRL, 190mRL, and 210mRL. Ore drive development from these levels will contribute to initial ore supply for the process plant.
