Horizonte Minerals PLC10 October 2006 The following amends the Drilling Report announcement released today at 0700under RNS number 2064K. The figure in the highlights line commencing DDH-4 should read 35.13 metres and not 36.25 metres. All other details remain unchanged, the full amended announcement appears below. 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 companyfocused on Brazil and Peru, is pleased to announce positive results from thefirst four holes of its 11 hole reconnaissance drill programme at its 100% ownedTangara gold project in the Carajas Mineral Province, Brazil. The results, withhighlights including 9.78g/t Au over 6.75 metres, indicate that the Company haslocated a large scale mineralized system that needs to be defined with furtherdrilling to quantify the extent of its potential. Highlights • DDH-4 - 35.13 metres averaging 2.54 g/t Au from 36.25 metres downholeincluding • 6.75 metres grading 9.8 g/t Au and a second interval of 2 metresgrading 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 withan interpreted breccia body hosted by mafic volcanics. The mineralization may berelated to a quartz feldspar porphyry intersected at the end of the hole. Goldgrades ranged from 47 ppb to a high of 22.2 g/t Au over 1.85 metres. Theweighted average of the zone being 37.28 metres grading 2.41 g/t Au withassociated elevated Cu, Pb, Zn, Ag and Mo.

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

Drill holes10 and 11 focused on targets some 750 metres west of DDH-4 while drill holes 5to 9 lie a further 1,200 metres to the west. These results will be reported indue course once all assays have been received. Horizonte CEO Jeremy Martin said: "We are highly encouraged by these grades andlook forward to receiving results from the remaining holes, which will enable usto further quantify the mineralization. Tangara is one of our core explorationprojects located in a highly prospective and known region for discovery. We aremobilising sample crews to carry out additional detailed soil sampling over thetarget area and we are already planning follow-up drilling to the currentcampaign. The results from DDH-4 demonstrate economic grades, which issignificant 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 ourintention to locate large scale ore bodies in proven districts and then farm inmajors, as we have done with Australian listed Troy Resources." Sampling, assaying, and QA/QC Procedures adopted by Horizonte in the collection, preparation and storage ofsamples from the auger drilling programme, conform to industry-wide bestpractice and with chain of custody being observed for all samples. Analysis isundertaken by ALS Labs at its laboratories in Vancouver, Canada, and the Companymaintains QA/QC on all analytical work via the inclusion of certified referencematerials and field duplicates and blanks, in addition to monitoring of thelaboratory's own internal check-analyses.

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