Tapajos Regional Exploration

Click to enlargeThe Tapajos Region of Brazil covers an area of 100,000 km2 (approximately equivalent to the area of Belgium). Within this Region, Serabi has concessions totaling approximately 273,000 hectares in eight prospective exploration targets.

Pombo

The Pombo prospect is loacted in the Southern Tapajos in Mato Grosso State, approximately 500 kilometres south of the Palito operations.  Extensive work had already been undertaken at Pombo prior to it's acquisition by Serabi.  Serabi's drilling has concentrated on the main east-west structure, with results confirming extensive gold-copper mineralisation across the central section, which included gold values of 0.98m @ 13.99 g/t and 0.62m @ 9.83 g/t.  Further drilling east and west of the central mineralised section indicates strong alteration, with associated sulphide mineralisation a further 100-150m along strike. 

Jutai

Jutai was originally identified as a bulk, low-grade system previously assessed by Rio Tinto.  Rio Tinto defined a preliminary oxide resource of 4.4 million tonnes grading 0.60 g/t gold containing approximately 85,000 ounces, mostly within the near-surface saprolite zone and over a strike length of approximately 1,600 metres.  Further work by Serabi is focussed on the historic resource area and includes preliminary metallurgical test work and a more detailed assessment of the nature of the mineralisation.

Castanheira

The Castanheira garimpeiro workings are located 150 kilometres to the south west of Palito.  While the area and its surroundings have extensive garimpeiro workings on a well-defined linear trend, there has been no systematic exploration of the area.  Surface garimpeiro workings extend over 1 kilometre along the strike and can now be identified as a number of flooded pits; management believes these features are likely to represent a mineralised vein system.  Serabi believes the exploration potential for Castanheira to be high.

Sucuba

Located 10 kilometres west of Palito, work has focussed on the area around existing garimpeiro workings.  Serabi has completed a 14 kilometre geochemsitry programme, which identified a number of gold and copper anomalies including a central, east-west feature some 800 metres long.  A further geochemistry programme indicates a continuation of the central anamoly for a further kilometre.  A limited drill programme during 2006 confirmed the presence in hard rock of gold, lead, zinc and silver mineralisation.  A further drill programme is planned.

Pizon

This is also an area of historic artisanal mining over which Serabi has recently completed a programme of reconnaissance geochemistry, field mapping and grid-augur drilling, together with stream sediment sampling.  Initial results have defined two gold-in-soil anomalies corresponding to mapped intrusive acid porphry bodies emplaced in an acid volcanic terrain.  The company has recently increased its land-holdings significantly around this prospect.

Igarape Salustiano and Ornifel-Sucuba

These exploration projects are situated directly along the strike of the Palito mine , and are situated within the regional Tocantinzinho structural trend.  As a result, management  believes these significant areas of unexplored land provide good exploration potential.

Modelo

Located close to the Transamazonica Highway, this prospect has significant garimpo workings but no modern exploration has taken place. Serabi has significantly increased its land holdings around this prospect.
