Emerging Cobar district explorer and developer Peel Mining Limited (ASX: PEX) is pleased to announce that Peel and CBH Resources Limited, a wholly owned subsidiary of Toho Zinc Co Ltd., have signed a binding Heads of Agreement related to EL7461 and ML1361, which includes the Mallee Bull copper-polymetallic discovery near Cobar.

Under the agreement, CBH has the right to earn an interest of up to 50% over a three-year period through staged expenditure on exploration and a contribution to previous exploration costs incurred by Peel.

CBH Resources is an Australian-based mineral resources company producing zinc, lead and silver from the Endeavour Mine north of Cobar. The company, which is 100%-owned by Tokyo Stock Exchange-listed Toho Zinc, is also commissioning the Rasp underground zinc, lead and silver mine at Broken Hill.

CBH brings a wealth of technical expertise and resources to Mallee Bull, particularly with regards to exploration and development within the Cobar Superbasin, and Peel looks forward to working with CBH at Mallee Bull, which is possibly the most significant mineral discovery in the Cobar District over the past 10 years.

Commenting on the agreement, Peel Managing Director Rob Tyson said:

“Peel welcomes CBH Resources as the company’s partner at Mallee Bull and the wider May DayGilgunnia project area. The recent results we have reported have confirmed the Mallee Bull prospect as a true greenfields copper-dominant discovery, and we believe that attracting a partner of CBH’s calibre is testament to the excellent potential of Mallee Bull. As an established producer in the Cobar region, CBH brings years of local experience to the project, and we look forward to working with CBH as exploration at Mallee Bull progresses.”

Background on Mallee Bull discovery

In March/April 2011, Peel began targeting a newly-recognised coincident EM and magnetic geophysical anomaly located within the historic 4-Mile goldfield. The 4-Mile goldfield comprises up to 60 shafts and workings spread over an area covering about 1,000m by 500m.

Initial drilling resulted in the discovery of significant silver-lead-zinc mineralisation. Follow-up drilling completed in July/August 2011 intersected massive sulphides containing strong copper-lead-zincsilver-gold-cobalt mineralisation within a broad zone of deformation and alteration, confirming the discovery of a Cobar-style mineralised system .

The Mallee Bull prospect is located less than 10 kilometres east of the May Day gold-silver-lead-zinc deposit (ML1361), where drilling in 2010 confirmed the down-dip continuation of mineralisation to more than 200m below surface.
