FINAL DRILL RESULTS FROM INFILL DRILLING PROGRAMME AT THE ARAGUAIA NICKEL PROJECT, BRAZIL

_____________________________________________________________________

10 September 2013 � Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) (�Horizonte� or �the Company�) the exploration and development company focused in Brazil, is pleased to announce the final set of results from the completed infill resource drilling programme at its 100% owned Araguaia nickel project (�Araguaia�) in Para State, north central Brazil. 

Highlights

�        New high grade nickel intersections at the Vila Oito Target include:

o   20.21 metres grading 2.29% Ni

o   13.48 metres grading 1.77% Ni

o   20.38 metres grading 1.68% Ni

�        New high grade nickel intersections from the Vila Oito West Target include:

o   7.22 metres grading 2.10% Ni

o   8.67 metres grading 1.76% Ni

o   9.37 metres grading 1.72% Ni

• 321 holes (9,309 metres) of the final Phase 3 infill drill programme completed on time and within budget targeting the Jacutinga, Vila Oito West, Vila Oito, Vila Oito East and Pequizeiro West targets at Araguaia.

• Geotechnical drilling as part of the Pre-Feasibility study (�PFS�) has been completed in the proposed pits on the Bai�o, Pequizeiro, Pequizeiro West, Jacutinga, Vila Oito West, Vila Oito and Vila Oito targets.  This drilling comprised a total of 12 holes (386 metres) � an additional 6 hole geotechnical drilling programme is currently underway on the proposed plant site.

Horizonte CEO Jeremy Martin said, �This is the final set of drill results from the infill resource drilling programme at Araguaia, which has been completed on time and on budget.  Both the Vila Oito and Vila Oito West target results are highly encouraging and have returned a number of drill holes with high nickel grades and good vertical thickness.  All of the results have now been integrated into the PFS which will result in an updated Resource Model as part of the overall study.  Snowden Mining Consultants, with the associated consulting groups, are making solid progress on the PFS study, with initial work complete on the plant site selection, initial mining design and preliminary mining schedule.  The programme is running to budget and is on schedule for completion in H1 2014.  An additional geotechnical drilling programme is underway on the selected plant site to determine the ground conditions around the planned locations of the principal structures namely; primary crusher, rotary kiln, electric furnace and the slag disposal facility. 

�Our exploration team has also been active, evaluating new potential targets within our extensive land position around the core Araguaia resources.  We look forward to providing further updates on the progress of the PFS and other exploration activity in the coming weeks.�

Further Details

These results are the final set of drill results from the Phase 3 mineral resource drilling programme.  This programme was designed to complete infill drilling on 100 m x 100 m grids on the Jacutinga, Vila Oito West, Vila Oito, Vila Oito East and Pequizeiro West targets of the Araguaia Nickel Project in Brazil.  321 holes (9,309 metres) were completed, including 35 holes (1,186 metres) on Jacutinga, 84 holes (1,669 metres) on Vila Oito West, 133 holes (4,228 metres) on Vila Oito, 44 holes (1,509 metres) on Vila Oito East and 25 holes (717 metres) on Pequizeiro West.  The results from the 71 holes (2,139 metres) from the 100m x 100m infill drilling on the Vila Oito target are detailed in Table 1.  The results from the 84 holes (1,669 metres) from the combined 141m x 141m and 100m x 100m infill drilling on Vila Oito West are detailed in Table 2.  The results contain several high-grade intersections, including 20.21 metres grading 2.29% nickel (Hole PCA-DD-1283), 13.48 metres grading 1.77% nickel (Hole PCA-DD-1266) and 20.38 metres grading 1.68% nickel (Hole PCA-DD-1270) on the Vila Oito target; 7.22 metres grading 2.10% nickel (PCA-DD-1310), 8.67 metres grading 1.76% nickel (PCA-DD-1357) and 9.37 metres grading 1.72% nickel (PCA-DD-1319) on the Vila Oito West target.

It should be noted that a number of the drill holes from these latest results step out around the edges of the main mineralised zones at the project area and as such not all the holes have encountered economic nickel grades at a 1% nickel cut off grade.   However where economic grades are intercepted then the drill programme will be expanded to infill around these areas.

NSI: No significant intersection

The compositing of the nickel grades in the individual holes was completed across geological boundaries using a nickel cut-off of 1% with a minimum intercept length of 2.0 metres and a maximum length of internal waste of 2 metres.  All holes were vertical and, as these nickel laterite deposits are essentially flat-lying, all widths given are true widths.  Core recoveries in the mineralised sections met the appropriate standards for this style of mineralisation and were generally >90%.

Sample preparation and analyses

Samples from drill core were crushed and pulverised at the SGS laboratory in Goiania and the resultant pulps analysed at the SGS laboratory in Belo Horizonte using tetraborate fusion and X-Ray Fluorescence (�XRF�).  Full QA/QC procedures were followed, including the insertion of standards, duplicates and blanks.  Check samples representing approximately 5% of all the samples, will be sent to another international laboratory for analysis by XRF.
