New High Grade Drill Results from Infill Mineral Resource Drilling Programme at the Araguaia Nickel Project, Brazil

LONDON, April 16, 2015 /CNW/ - Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ('Horizonte' or 'the Company') the nickel development company focused in Brazil, is pleased to announce the completion of its infill resource drilling programme at its 100% owned Araguaia nickel project ('Araguaia') in Para State, north central Brazil where initial results have demonstrated significant new high grade drill intersections (>2% Ni).

Highlights

  • New high grade nickel intersections from completed infill resource drilling on the Pequizeiro deposit include:
    • 9.66 meters grading 2.28% Ni
    • 2.29 meters grading 2.17% Ni
    • 10.80 meters grading 2.13% Ni
    • 20.17 meters grading 2.09% Ni
  • Seven rig, 10,255 metre infill resource drill programme designed to convert initial 7-8 years of the 25 year modelled mine life to the Measured resource category
  • Final infill drill results due Q2 2015

Horizonte CEO Jeremy Martin said, "We have completed the infill resource drilling programme at Araguaia on time and within budget; with the initial results received to date continuing to demonstrate the consistent high grade nature of the mineralisation.  The aim of the programme is to convert the first 7 to 8 years of the modelled mine life to the Measured Resource category and in the process give a higher degree of confidence around the nickel mineralisation for this part of Araguaia's projected production. 

"In addition, we are now in the final phase of the geotechnical and hydrogeological drilling programme across the proposed process plant site which will provide detailed information on ground conditions to assist in the design of the process plant structures.  This will be completed in Q2 2015 and I look forward to providing further updates on this and infill resource assay results in due course."

Further Details
Infill Mineral Resource Drilling
The phase 4 mineral resource drilling programme was designed to complete infill drilling on 50m x 50m grids on selected parts of the Pequizeiro and Jacutinga deposits.  The completed programme comprised a total of 310 holes totalling 10,255 metres, 261 holes totalling 8,764 metres on the Pequizeiro deposit and 49 holes totalling 1,491 metres on the Jacutinga deposit. The results received to date for 43 holes on the Pequizeiro deposit are presented in Table 1 below. These results contain several high grade intersections including 9.66 meters grading 2.28% nickel (hole PCA_DD_1518), 2.29 meters grading 2.17 nickel (hole PCA_DD_1507), 10.80 meters grading 2.13% nickel (hole PCA_DD_1511) and 20.17 meters grading 2.09% nickel (hole PCA_DD_1477).

Additional Geotechnical and Hydrogeological Drilling:
This drilling work will be completed in late April 2015.

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 ALS laboratory in Goiania and the resultant pulps analysed at the ALS laboratory in Lima, Peru 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.

Horizonte Minerals prepared this news release and David Hall BSc, MSc, Fellow SEG EurGeol. a director of the Company and Qualified Person under National Instrument 43-101, reviewed and approved the drillhole technical information.

About Horizonte Minerals:
Horizonte Minerals plc is an AIM and TSX-listed nickel development company focused in Brazil, which wholly owns the advanced Araguaia nickel laterite project located to the south of the Carajas mineral district of northern Brazil. 

The Company is developing Araguaia as the next major nickel mine in Brazil, with targeted production by late 2017 early 2018. 

The Project, which has excellent infrastructure in place including rail, road, water and power, has a current NI 43-101 compliant Mineral Resource of 71.98Mt grading 1.33% Ni (Indicated) and 25.4Mt at 1.21% Ni (Inferred) at a 0.95% nickel cut-off; included in Resources is a Probable Reserve base of 21.2Mt at 1.66%Ni.

A Pre-Feasibility Study has been completed which underpins the robust economics of developing a mine with a targeted 15,000tpa nickel in ferro-nickel output with a 20% Fe-Ni product over a 25 year mine life utilising the proven pyrometallurgical process of Rotary Kiln Electric Furnace technology.  At these production rates, the project has a post-tax NPV of US$519m at a discount rate of 8% and an IRR of 20%, with a capital cost of US$582m which puts this project in the lowest quartile of the cost curve.

Horizonte has a strong shareholder structure including Teck Resources Limited 38.5%, Henderson Global Investors 14%, Anglo Pacific Group 7%.
