Positive results from infill drilling programme & successful metallurgical testing at Araguaia Nickel Project, Brazil

TORONTO, Jan. 8, 2013 /PRNewswire/ - Horizonte Minerals Plc, (AIM: HZM), (TSX: HZM) ('Horizonte' or 'the Company') the exploration and development company focused in Brazil, is pleased to announce continuing positive results from the on-going infill resource drilling programme at its 100% owned Araguaia Nickel Project ('Araguaia') in Para State, north central Brazil.

Highlights

  • 81 holes (2,653 metres) of the infill drill programme completed to date (commenced on 18 September 2012) targeting the Jacutinga, Vila Oito, Vila Oito East and Pequizeiro West targets at Araguaia
  • New high grade intersections at the Jacutinga target include:
    • 23.2 metres grading 2.09% Ni (including 10.1 metres grading 2.91% Ni)
    • 9.1 metres grading 2.11% Ni
    • 16.2 metres grading 1.73% Ni
    • 14.1 metres grading 1.62% Ni
  • FLSmidth confirmed Araguaia ore is suitable for metallurgical treatment via the high temperature Rotary Kiln-Electric Furnace route, a proven process technology
  • Pre-Feasibility Study contract expected to be awarded in Q1 2013

Horizonte CEO Jeremy Martin said, "There is a considerable amount of activity taking place at the Araguaia Project.  We currently have four drill rigs operating on the infill resource drilling programme with the aim of completing 7,000 metres of drilling to convert approximately 50 million tonnes of the higher grade material to the Indicated Category.  The drilling at the Jacutinga target was completed in December 2012 and we are pleased to report a number of high grade intercepts including 23.2 metres grading 2.09% nickel.

"In addition to the resource drilling programme, we have just completed metallurgical test work with the global leader in high temperature kiln technology, FLSmidth.   The test work was designed to evaluate the expected ore performance in rotary kiln processing and we are pleased to report that Araguaia ore was found to be suitable for treatment using this technology.  Rotary kiln processing is a key step in the well established Rotary Kiln-Electric Furnace pyro-metallurgical process that we are aiming to utilise at Araguaia.  Consequently, the success of the metallurgical test work marks another major step in de-risking Araguaia and demonstrates that the ore can be processed using proven technology.  Work is now focused on moving the project into the pre-feasibility stage and we hope to award the pre-feasibility study contract in Q1 2013."

Further Details

The drill results have been collated from the Phase 3 mineral resource drilling programme that commenced in September 2012.  This programme is designed to complete infill drilling on 100 metre x 100 metre grids on the Jacutinga, Vila Oito, Vila Oito East and Pequizeiro West targets of the Araguaia Nickel Project in Brazil.  To date, 81 holes (2,653 metres) have been completed.  The results from 24 holes (808 metres) from the Jacutinga target received to date are detailed in Table 1.  The results contain several wide, high-grade intersections, including 23.2 metres grading 2.09% nickel (Hole PCA-DD-1111).  This intersection includes a continuous length of 10.10 metres grading 2.91% nickel; 9.09 metres grading 2.11% nickel (Hole PCA-DD-1103); 16.1 metres grading 1.73% nickel (Hole PCA-DD-1118) and 14.1 metres grading 1.62% nickel (PCA-DD-1122).

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.

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.

FLSmidth Kiln Test Work

Two blends of Araguaia laterite were submitted to the laboratories of FLSmidth (http://www.flsmidth.com) located in Bethlehem, Pennsylvania, USA, for rotary kiln evaluation testing.  The overall results of the study show that Araguaia ore is suitable for rotary kiln processing; a range of suggested kiln operating conditions were indicated. The testwork included the following:

  • Physical analysis, including moisture content, bulk density, angle of repose, wet and dry particle size distribution and particle degradation in tumble testing;
  • Chemical analysis and ore thermal analysis;
  • Ore reduction and sintering tests including small scale briquetting tests.

The determined properties of the two Araguaia blends show that the material is amenable to high temperature kiln processing.  The dry particle size distribution data and the results of the tumble testing were found to be generally comparable to those of a number of laterite ores currently handled in commercial Rotary Kiln-Electric Furnace operations. The sintering tests established the range of kiln operating temperatures.  In the ore reduction tests, the degree of iron reduction was considered normal, and while a somewhat lower degree of nickel reduction was obtained, this result does not materially affect overall Rotary Kiln-Electric Furnace performance. Some additional metallurgical testwork is on-going and is expected to be completed during Q1 2013.  This includes a mineralogical study on one of the ore blends tested at F.L. Smidth, and measurements of the Araguaia slag melting point.

When growing capacity and power in the data center, the architectural trade-offs between server scale-up vs. scale-out continue to be debated.
