Drilling Report

Horizonte Minerals PLC 10 October 2006 Horizonte Minerals plc / Index: AIM / Epic: HMZ / Sector: Mining 10 October 2006 Horizonte Minerals plc ('Horizonte' or 'the Group') HORIZONTE INTERCEPTS 35 METRES GRADING 2.54 g/t Au AT TANGARA BRAZILIAN GOLD PROJECT Horizonte Minerals plc, the AIM listed exploration and development company focused on Brazil and Peru, is pleased to announce positive results from the first four holes of its 11 hole reconnaissance drill programme at its 100% owned Tangara gold project in the Carajas Mineral Province, Brazil. The results, with highlights including 9.78g/t Au over 6.75 metres, indicate that the Company has located a large scale mineralized system that needs to be defined with further drilling to quantify the extent of its potential. Highlights • DDH-4 - 36.25 metres averaging 2.54 g/t Au from 36.25 metres downhole including • 6.75 metres grading 9.8 g/t Au and a second interval of 2 metres grading 6.0 g/t Au • Au-Cu-Zn-Ag-As values indicate large scale mineralized system Drill hole DDH-4 intersected a broad zone of gold mineralization associated with an interpreted breccia body hosted by mafic volcanics. The mineralization may be related to a quartz feldspar porphyry intersected at the end of the hole. Gold grades ranged from 47 ppb to a high of 22.2 g/t Au over 1.85 metres. The weighted average of the zone being 37.28 metres grading 2.41 g/t Au with associated elevated Cu, Pb, Zn, Ag and Mo.

The Company interpret this zone to be outboard of the main mineralization. A review of all geochemistry will be undertaken when all results are received.

Drill holes 10 and 11 focused on targets some 750 metres west of DDH-4 while drill holes 5 to 9 lie a further 1,200 metres to the west. These results will be reported in due course once all assays have been received. Horizonte CEO Jeremy Martin said: 'We are highly encouraged by these grades and look forward to receiving results from the remaining holes, which will enable us to further quantify the mineralization. Tangara is one of our core exploration projects located in a highly prospective and known region for discovery. We are mobilising sample crews to carry out additional detailed soil sampling over the target area and we are already planning follow-up drilling to the current campaign. The results from DDH-4 demonstrate economic grades, which is significant in a reconnaissance drill programme. 'Elsewhere we are awaiting results from our El Aguila drill programme in Peru, which we believe will underline the potential the area possesses. It is our intention to locate large scale ore bodies in proven districts and then farm in majors, as we have done with Australian listed Troy Resources.' Sampling, assaying, and QA/QC Procedures adopted by Horizonte in the collection, preparation and storage of samples from the auger drilling programme, conform to industry-wide best practice and with chain of custody being observed for all samples. Analysis is undertaken by ALS Labs at its laboratories in Vancouver, Canada, and the Company maintains QA/QC on all analytical work via the inclusion of certified reference materials and field duplicates and blanks, in addition to monitoring of the laboratory's own internal check-analyses.

The Group has two gold exploration projects in Brazil, and one silver-zinc-lead project in Peru. The two Brazilian gold projects, Tangara and Falcao, are located to the south of the highly prospective Carajas Mineral Province. Both projects cover an area of approximately 300 km(2) and are centred over greenstone belts, with known gold mineralisation from previous exploration. The scale of these project areas, the overall aerial extent of the mineralised system and the high density and magnitude of related gold anomalies (identified in river sediments, surface soils and rocks), indicate the potential for multiple deposit discoveries. The silver-zinc-lead project is located in the historic mining district of Cerro de Pasco in Central Peru. Sampling and drilling on this project has demonstrated the high grade potential of this project. The Group has a joint venture with Australian gold producer Troy Resources NL's 70% owned local subsidiary Sertao Mineracao Ltda to advance its Goias Velho gold exploration project in Brazil.
