Horizonte Secures ?8 Million Financing

____________________________________________________________________

27 June 2013 - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company') the exploration and development company focused in Brazil, is pleased to announce that further to the news release of 11 June 2013, it has signed an agreement for an ?8 million Equity Financing Facility ('EFF') with Darwin Strategic Limited ('Darwin'), a majority owned subsidiary of Henderson Global Investors' Volantis Capital.

Commenting, Jeremy Martin, Chief Executive of Horizonte Minerals said, "We are pleased to have secured this ?8 million financing facility with Darwin.  Whilst there are no plans to utilise this facility as we have a robust cash position, we feel it is important to have additional flexibility in terms of future funding, given the current economic climate.

"This agreement also underpins Darwin's support and commitment to Horizonte as we continue to advance our flagship Araguaia nickel project, located south of the world-class Carajas mining province in northern Brazil, through its pre-feasibility study with the aim  of developing  the next major nickel project in Brazil."   

Further details of the Equity Finance Facility

The EFF agreement with Darwin provides Horizonte Minerals with an equity line facility of up to ?8 million which (subject to certain conditions and restrictions) can be drawn on any time over the next three years. The floor subscription price in relation to each draw down ('the Floor Price') is set at the discretion of the Company.

Horizonte Minerals is under no obligation to make a draw down and there are no penalty fees if the Company does not use the facility. The Company may make drawdowns at its discretion during the term, up to the total value of the EFF, by issuing subscription notices (each a 'Subscription Notice') to Darwin. Following delivery of a Subscription Notice, Darwin will, subject to certain conditions, subscribe for and the Company will allot and issue new ordinary shares in the capital of Horizonte Minerals ('Ordinary Shares').

The subscription price for any Ordinary Shares to be subscribed for by Darwin will be set with reference to the average of the three lowest Closing Bid Prices (as defined in the EFF) in the period following the issuance of the Subscription Notice, subject to the Floor Price set by the Company in each Subscription Notice, below which Ordinary Shares will not be issued. The Company may, with Darwin's consent, modify the Floor Price at any time during each relevant pricing period.

The maximum number of Ordinary Shares which may be issued under a Subscription Notice is the lower of: 25% of the Company's issued share capital following completion of the relevant draw down; and four times the average daily trading volume of the Company's Ordinary Shares over the 15 trading days preceding the issuance of the relevant Subscription Notice. This maximum indicated above may be reduced in certain circumstances, including in the event the subscription price is below the Floor Price. In addition, the maximum amount of any individual Subscription Notice must not exceed ?500,000, unless consented to by Darwin. The Company holds an over-allotment option, under which it may authorise Darwin in a Subscription Note, at Darwin's discretion, to increase the amount of such draw down by up to the then aggregate undrawn amount under the EFF.

Darwin is entitled to a cash commission of 5% of the value of each draw down, however Darwin and the Company may by mutual agreement elect that, in lieu of such cash payment, the subscription price in respect of such draw down be discounted by 5%.

Darwin may, with the Company's consent, direct that its obligations to complete a draw down pursuant to a Subscription Note be satisfied by its parent fund, Henderson Volantis.

Darwin and Horizonte Minerals may mutually agree at the end of the pricing period to a variation of the applicable subscription price. This may allow for a larger subscription via any over-allotment facility authorised by the Company.

The issuance of a Subscription Notice is conditional upon the satisfaction of certain Subscription Notice Conditions, as indicated in the EFF, including shareholder and regulatory consents and approvals (including from the TSX), as applicable.

Darwin and Horizonte Minerals each may terminate the EFF upon the occurrence of certain defaults by the other party. In addition, the Company may terminate the agreement upon 1 month's written notice. Darwin may terminate at its discretion during a 4 month period commencing 4 months after the date of signature.
