Horizonte Raises £3.08 Million to Support Work on Pre-Feasibility Study on the Araguaia Nickel Project

____________________________________________________________________

11 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 a placing ('the Placing') of 41,093,327 new ordinary shares ('the Placing Shares') at 7.5 pence per ordinary share to raise proceeds of £3.082 million before expenses. Following this placing the Company will have a net cash position of £7.3 million.

The proceeds of the Placing will be used to fund Horizonte's 100%-owned Araguaia Nickel Project ('Araguaia' or 'the Project'), located south of the Carajas mining district in northern Brazil, to the end of the Pre-Feasibility Study ('PFS'). Horizonte is currently in the final stages of awarding the PFS contract with work due to begin in H2 2013.

Additionally Horizonte has entered into a term sheet to put in place an Equity Financing Facility ('EFF') for up to £8.0 million over a period of 36 months with Darwin Strategic Limited ('Darwin'), a majority owned subsidiary of Henderson Global Investors ('HGI'). The EFF provides Horizonte with funding optionality, however the facility is at Horizonte's option and there are no plans in place to utilise the EFF in the foreseeable future.

Horizonte Chief Executive Officer Jeremy Martin said, "This fundraise underpins the continued strong support we have from our major shareholders with regards to the economic potential and development of our Araguaia Nickel Project in Brazil. This is an exciting time as we approach the commencement of our PFS using the proven Rotary Kiln Electric furnace ('RKEF') process. An updated mineral Resource estimate is also currently being prepared by Snowden Mining Consultants after the completion of a 10,000m infill Resource drilling programme with a view to updating the current NI 43-101 compliant Resource of 39.3Mt grading 1.39% Ni (Indicated) and 60.9Mt at 1.22% Ni (Inferred) at a 0.95% nickel cut-off.

"The Placing also ensures the Company is well funded with £7.3 million in the bank and in robust shape against a backdrop of tough market conditions. The funds will see the Company through the PFS at Araguaia and into 2014. The second half of 2013 is going to be an active time for Horizonte and we look forward to updating shareholders on the progress of the Pre-Feasibility study."

Details of the fundraising

The Placing comprises a conditional placing of a total of 41,093,327 new ordinary shares at 7.5 pence per ordinary share through finnCap Ltd ('finnCap') as agent for the Company.

The Placing is conditional, inter alia, upon admission to trading on AIM of the Placing Shares and subject to the terms and conditions of a Placing agreement entered into between Horizonte and finnCap.

Under the Placing, Teck Resources Limited ('Teck') has agreed to subscribe for 20,000,000 new ordinary shares (the 'Teck Placing Shares') and HGI has agreed to subscribe for 12,133,329 new ordinary shares.

The Placing Shares will, when issued, rank pari passu in all respects with the existing ordinary shares of the Company. Applications have been made to the London Stock Exchange for the Placing Shares to be admitted to trading on AIM and to the Toronto Stock Exchange for the Placing Shares to be listed on the TSX.

The Placing is being undertaken in two tranches. The first tranche comprises of 21,093,327 ordinary shares (being the Placing Shares less Teck's Placing Shares) ('First Placing Shares') for which admission is expected on 12 June 2013. The second tranche comprises of the Teck Placing Shares and is conditional on admission of the first tranche. Admission of the second tranche is expected on 13 June 2013.

Settlement Details

Teck currently holds 150,573,987 ordinary shares in the Company, representing 41.8 per cent of the current issued share capital. As part of the Placing, Teck has agreed to subscribe for 20,000,000 Placing Shares, representing 48.7 per cent of the Placing Shares being offered. Assuming all the Placing Shares are issued as currently envisaged, Teck's holding in the enlarged issued share capital would therefore be 170,573,987 ordinary shares, representing 42.5% of the enlarged issued share capital immediately following the Placing.

Under Rule 9 of the UK City Code on Takeovers and Mergers (the 'Code'), when any person, together with persons acting in concert with him, is interested in shares which in aggregate carry not less than 30% of the voting rights but does not hold shares carrying more than 50% of the voting rights of such a company, a general offer will normally be required if any further interests in shares are acquired by any such person which increases the percentage of shares carrying voting rights in which he is interested. An offer would have to be made in cash at a price not less than the highest price paid by him, or by any member of the group of persons acting in concert with him, for any interest in shares in the company during the 12 months prior to the announcement of the offer.

In order to eliminate the unexpected possibility of Teck's percentage interest in the Company's ordinary shares increasing by more than 1 per cent following the Placing, it has been decided to split the issue of the Placing Shares (and consequently Admission) so that the First Placing Shares are issued and admitted to trading on AIM on 12 June 2013 and the Teck Placing Shares are issued and admitted to trading on AIM on 13 June 2013 conditionally upon Admission of the First Placing Shares having become effective and payment having been made therefor. This would imply that, on 12 June 2013, Teck's percentage interest in the then issued share capital of the Company reduces to 39.5 per cent before increasing again on 13 June 2013 to 42.5 per cent.

Whilst the increase of Teck's percentage interest would, prima facie, trigger a mandatory offer under Rule 9 of the Code, the Panel has agreed, based on the intention of the parties, to waive the requirement in this instance.

Following Admission of the second tranche of Placing Shares, the Company's share capital will consist of 401,139,497 ordinary shares of 1 penny each, all with voting rights. The above figure may be used as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure and Transparency Rules.

Related Party Transactions

By reason of their existing share holdings in the Company, the participations of Teck and HGI in the Placing each constitute a related party transaction under AIM Rule 13 of the AIM Rules for Companies.

The directors of the Company consider, having consulted with finnCap Ltd, that the terms of the Placing with Teck and HGI are fair and reasonable insofar as its shareholders are concerned.
