Herencia Resources plc (AIM:HER) is pleased to announce that it has signed a binding Term Sheet, with OZ Exploration Chile Limitada ("OZE"), a wholly owned subsidiary of OZ Minerals Limited ("OZL"), in relation to the potential acquisition by OZE for a controlling interest in the Guamanga IOCG Project in Chile.

Herencia, Resources plc ("Herencia" or "the Company"), the Chile-focussed mineral exploration and development company, has signed a binding Term Sheet with OZ Exploration Chile Limited ("OZE"), a subsidiary of OZ Minerals Limited a company listed on ASX ("OZL") to progress the Guamanga Copper-Gold Project located in northern Chile. The Term Sheet is subject to final due diligence by OZE on the Guamanga mining concessions, to be conducted over the next 30 days.

The key components of the Term Sheet that the parties will in good faith negotiate, to form a joint venture agreement, are as follows:

·; Phase 1 - OZE to sole fund an initial US$3 million over 20 months to earn a 51% stake in the Guamanga Project.

·; Phase 2 - OZE to sole fund an additional US$5 million over 24 months to increase their stake to 80%.

At the completion of Phase 2, it is proposed Herencia will have the option to either remain at 20% (by co-contributing 20% of funds spent) or may opt for OZE to fund a further US$5M to increase the OZ equity to 90% (Phase 3).

At the completion of Phase 3, it is also proposed Herencia may elect to fund its share of project development costs, or OZE, at their election, may consider the provision of providing debt funding to Herencia with the funding to be repaid to OZE from Herencia's share of profits.

OZE can elect to terminate the Term Sheet at any time, by giving Herencia one month's written notice.

To facilitate the process outlined above, Herencia has purchased 100% of the Guamanga Project from Inversiones Santa Patricia Limitada ("Santa Patricia"), by paying an initial US$100,000 with a further US$175,100 to be paid in 6 month time and within 30 days following the signing of the Herencia-Santa Patricia Agreement, the issuance to Santa Patricia of US$950,000 of Herencia shares at a 20 day volume weighted average price from the date of signing the Agreement. A further announcement will be made when the consideration shares are issued.

Graeme Sloan, Managing Director of Herencia commented:

"OZ Minerals Limited is recognised as one of Australia's leading copper producing companies with a team of very experienced personnel and I am extremely pleased to partner with OZL on one of our most exciting assets.

This Agreement highlights that our asset base and technical team in Chile continue to attract the attention and interest of leading global resource companies.

We see Herencia as becoming the 'partner of choice' for those entering into and advancing mining projects in Chile.

This Agreement demonstrates that Herencia will continue to advance our Projects in what we believe to be the best value-add structure for shareholders at any given time.

A key objective for Herencia is not only to advance our Project, but to look objectively for the best structure that achieves that outcome. In this case that means working closely with OZ Minerals, a leading Australian copper mining company, to progress the Guamanga Project."
