Exploration Release

SERABI MINING plc ("Serabi" or "the Company) Exploration results indicate growing resource potential across the Jardim do Ouro district Serabi Mining plc (SRB: AIM) announces further exploration success at the Palito mine and adjacent Jardim do Ouro district. * Palito West - structural continuity extended from 80 metres to 200 metres, together with high-grade drill intersections. Geophysical tests along strike indicate this structure continues to the south-east and may become very significant in the future of the Palito operations. * Chico da Santa - new interpretation indicates expansion of the area of mineralization following successful geophysical survey and its close proximity to the existing Palito underground mining operation, potentially allowing the project to be incorporated into the production schedule earlier than expected; subsequent drill follow-up has resulted in positive results. * Ruari's Ridge - exploration adit commenced in August from the north-west limit of the payable mineralised zone to enable detailed investigation of mining potential. * Palito Main Zone - down-dip drilling continues to demonstrate good grades and depth continuity. * Fixed Loop Electromagnetic ("FLEM") geophysical surveys prove to be a key exploration tool at Palito. Following this success in highlighting potential new mineralisation, Serabi has contracted to fly a helicopter electromagnetic survey over the entire Jardim do Ouro district during Q4 2007; the benefit of this rapid assessment is expected to provide numerous drill ready targets by year-end. * New potential will be incorporated into a year-end resource review. Since April 2007, exploration activity around the Palito mine / Jardim do Ouro concessions has been accelerated following a number of key successes (see Exploration Update press release, dated June 4). These have included excellent drill results at Palito West, the discovery and continued success at the Ruari's Ridge prospect and successful FLEM geophysical surveys at Palito South, and most spectacularly at Chico da Santa. The recent discoveries at the Ruari's Ridge and Chico da Santa prospects and extended success at Palito West will hopefully provide the basis for near term production expansion. Detailed evaluation of these satellites is now underway, through a 12,000 metre drilling programme, trenching and aerial geophysics. This work will culminate in an updated geological resource at the year-end, together with a new mine production plan. Palito West Located 200 metres to the south-west of the Palito mine, Palito West was reported in the Exploration Update of March 26. Since then, additional drilling has been ongoing and assays received. Previous drilling and sampling defined Palito West mineralisation as a single feature over 80 metres strike length and to a vertical depth of 50 metres. The previously reported holes were part of a drill programme designed to test the zone to the south in preparation for an "on-lode" development. Recent significant assays returned are as follows: +-------------------------------------------------------------------+ | | From | | Interval | Au(g/t | Cu | | Hole | (m) | To (m) | (m) | Au) | (%) | |---------------------+--------+--------+-----------+--------+------| | | 23.54 | 24.54 | 1.00 | 24.64 | 0.63 | | |--------+--------+-----------+--------+------| | PDD0281* | 40.40 | 41.30 | 0.75 | 1.81 | 0.11 | | |--------+--------+-----------+--------+------| | | 88.70 | 91.62 | 2.92 | 1.19 | 0.04 | |---------------------+--------+--------+-----------+--------+------| | PDD0298 | 33.73 | 34.40 | 0.67 | 3.18 | 0.65 | |---------------------+--------+--------+-----------+--------+------| | PDD0300 | 38.75 | 40.24 | 1.49 | 24.50 | 0.41 | |---------------------+--------+--------+-----------+--------+------| | PDD0302 | 49.33 | 50.00 | 0.67 | 66.30 | 2.00 | |---------------------+--------+--------+-----------+--------+------| | PDD0305 | 44.82 | 45.44 | 0.62 | 96.50 | 2.20 | +-------------------------------------------------------------------+ (* previously reported with results from Palito Laboratory only) The intersections in PDD0298, PDD0300, PDD0302 and PDD0305 and in PDD0281 of 2.92m @ 1.19g/t gold represent intersections on the interpreted main Palito West Zone. Two recent holes, PDD0334 and PDD0339 have intersected excellent visual sulphide rich mineralisation, which fit the Palito West projected position and extend the strike length to at least 200 metres. A strong geophysical electromagnetic (EM) conductor a further 200 metres south-east of PDD0334 indicates further strike extension potential. Interpretation also suggests a second parallel lode to Palito West approximately 40 metres to the north-east, which returned intercepts in PDD0281 of 1.0 metre @ 24.64g/t gold and 0.63% copper and includes historical intercepts in PDD0270 of 0.66 metre @ 13.62 g/t gold. Following these encouraging results the potential to expand the Palito West resource is being accelerated to optimise capital development planning required to bring the deposit into production as quickly as possible. Initial detailed follow-up consists of an enlarged programme of 40 x 40 metre spaced resource drilling now designed to investigate a target zone of 200 meters strike and 150 meters depth, a substantially larger zone than first anticipated. On surface the mineralised zone is being exposed for surface sampling along the strike length. This will also provide early production in Q4 of this year. [see attached link to access diagram] Plan View of Palito West Mineralisation Ruari's Ridge The discovery of significant mineralization at Ruari's Ridge was reported in the Exploration Update, dated June 4. Initial drilling and trenching highlighted up to four mineralised zones, with structural continuity for 3 zones of up to 900 metres and 300 metres vertical depth, of which the most prominent zone has been confirmed on surface by trenches for over 600 metres. Following these discoveries a detailed exploration and evaluation drilling programme has commenced over a central targeted area with a strike of 600 metres and 150 metres vertical depth. Thirty three (33) diamond drill holes have been completed (8,000 metres), 30 assayed to date, 3 awaiting assay and sixteen (16) trenches have been cut. The significant results returned from this campaign are listed below. A further 4,000 metres (15 holes) are now planned to assess the strike extension. The revised target block will be drilled on a 50 x 50 metre grid, to investigate the top 150 metres, with deeper holes below the top 150 metres every 100 to 150 metres along strike.

While the zones continue to exhibit structural continuity to the north-west, gold and copper values decrease, eventually becoming barren some 150 metres north of the airstrip. To the south-east the zones remain very open. At times, though massive sulphides and quartz are absent, alteration and disseminated sulphides are always present in the structures. The current southerly extension approximately 600 metres south of the runway has good structure, and remains open with the possibility of continuity towards a geochemistry anomaly 300 metres further south. There is currently no EM survey to the south. Results have been sufficiently encouraging for an exploration adit "in-ore" to start at the northern extent of the zone. This adit will be mined at the 250m elevation and will be driven south to investigate in detail the economic viability of the mineralisation. [see attached link to access diagram] Recent FLEM results in the Chico da Santa and Palito South areas highlight strong correlation with known areas of mineralisation Chico da Santa Interpretation based on 11 older drill holes had shown three, high-grade structures at Chico da Santa with limited strike and dip. During the second quarter this year Serabi undertook a FLEM survey over the property, with extremely encouraging results that now suggest Chico da Santa is a much more significant project than previously thought. As a result, exploration activity has accelerated here dramatically. Current Status: * Up until April 2007, 1,326 metres of Reverse Circulation (RC) and 4,700m of diamond core (DC) drilling were completed, establishing continuity of 200 metres strike and 100 metres dip length for 3 zones. * Since April the FLEM survey has been completed and numerous EM conductors clearly defined, resulting in a new geological interpretation. * Since April, 14 holes have been drilled, 8RC and 6DC. These have now identified 5 mineralized zones, highlighted by the holes that recorded intersections as follows: +-------------------------------------------------------------------+ | Hole | From | To | Interval | Au | Cu | | | (m) | (m) | (m) | (g/t ) | (%) | |-----------------+---------+--------+-----------+--------+---------| | | 63.28 | 64.20 | 0.92 | 1.07 | 0.03 | | PDD0303* |---------+--------+-----------+--------+---------| | | 73.81 | 74.37 | 0.56 | 10.20 | 0.39 | |-----------------+---------+--------+-----------+--------+---------| | | 78.40 | 79.04 | 0.64 | 0.60 | 0.04 | | PDD0308* |---------+--------+-----------+--------+---------| | | 136.45 | 137.00 | 0.55 | 43.20 | 1.40 | |-----------------+---------+--------+-----------+--------+---------| | PDD0320 | 58.16 | 60.57 | 2.41 | 19.79 | 1.73 | |-----------------+---------+--------+-----------+--------+---------| | | 70.55 | 73.00 | 2.45 | 2.37 | 0.03 | | PDD0328 |---------+--------+-----------+--------+---------| | | 76.04 | 76.59 | 0.55 | 6.14 | 0.03 | |-----------------+---------+--------+-----------+--------+---------| | | 103.73 | 104.70 | 0.67 | 5.92 | 0.60 | | PDD0335 |---------+--------+-----------+--------+---------| | | 120.42 | 120.94 | 0.52 | 1.16 | 0.05 | |-----------------+---------+--------+-----------+--------+---------| | PDD0341 | 188.62 | 189.96 | 1.34 | 3.63 | 0.61 | |-----------------+---------+--------+-----------+--------+---------| | Including | 189.42 | 189.96 | 0.54 | 6.70 | 0.68 | |-----------------+---------+--------+-----------+--------+---------| | RC-CS-009 | 39.00 | 44.00 | 5.00 | 3.33 | 0.30 | |-----------------+---------+--------+-----------+--------+---------| | Including | 40.00 | 41.00 | 1.00 | 13.30 | 0.81 | |-----------------+---------+--------+-----------+--------+---------| | | 1.00 | 4.00 | 3.00 | 1.02 | 0.01 | | RC-CS-016 |---------+--------+-----------+--------+---------| | | 6.00 | 8.00 | 2.00 | 1.51 | 0.01 | |-----------------+---------+--------+-----------+--------+---------| | RC-CS-018 | 34.00 | 35.00 | 1.00 | 1.42 | 0.01 | |-----------------+---------+--------+-----------+--------+---------| | RC-CS-020 | 29.00 | 31.00 | 2.00 | 2.37 | 0.12 | |-----------------+---------+--------+-----------+--------+---------| | RC-CS-021# | 79.00 | 81.00 | 2.00 | 10.27 | 0.33 | |-----------------+---------+--------+-----------+--------+---------| | RC-CS-022# | 28.00 | 29.00 | 1.00 | 9.56 | 0.01 | |-----------------+---------+--------+-----------+--------+---------| | | 8.00 | 11.00 | 3.00 | 1.30 | 0.01 | | |---------+--------+-----------+--------+---------| | | 71.00 | 72.00 | 1.00 | 1.40 | 0.06 | | RC-CS-023# |---------+--------+-----------+--------+---------| | | 79.00 | 80.00 | 1.00 | 1.87 | 0.02 | | |---------+--------+-----------+--------+---------| | | 101.00 | 102.00 | 1.00 | 1.22 | 0.14 | +-------------------------------------------------------------------+ ((*) previously reported with results from Palito Laboratory only) ((#) full results of holes pending) * While intersections are narrow, some very high gold values do occur. * Following the success of the FLEM survey, the most easterly three structures, C1, C2 and C3 will be drilled over a significantly larger target area than originally planned, with substantially longer strike extensions. The strike of zones also shows a 290° - 310° orientation, indicating the Chico da Santa zones will intersect the Palito Main Zone mineralization at current mine elevations, thereby providing easier and earlier production possibilities. * Some 6,000 metres of drilling is now planned over a 40 x 40 metre grid, along 450 metres strike and 150 metre depth. In addition, up to 20 trench sections will also be carried out. * Trenching in underway to confirm the surface mineralisation on coincident FLEM and geochemical anomalies with results from three trenches received to date.

The Palito Main Zone (PMZ) The PMZ will continue to be the 'backbone' of production for the coming year. The decline ramp is now developing below the 144 metre level, and with levels 210, 192, 178, 163 and now 144metre levels in various stages of production and development, the PMZ has over one year of production stoping 'blocked out'. Further ore lies in the existing levels and planned levels to the 100 meter elevation. In the southern half of the mine, there are drill indicated and drill inferred resources to the 50 metre elevation i.e. approximately 150 metres vertical depth. It is envisaged the decline will be developed to the 100 metre level by Q1 2008. During Q4 2007 and Q1 2008, deep drilling to test the down dip extensions of the PMZ will be undertaken to test the potential extension of the PMZ to the 0 m level and also to optimize the capital development to that level. Subject to the continuity of the resource at depth, it is estimated there is approximately 5,000 tonnes per vertical metre of diluted resource. At a current annual production rate of approximately 200,000 tonnes, approximately 2 levels are exhausted in the PMZ each year. New Production Potential & Resource Update With the potential to expand the Palito West resource in the very near future, a scoping study is now underway to incorporate Palito West into the proposed capital development of the Ruari's Ridge deposit, some 100 metres to the south-west via a decline access. The geological resource has not been updated since January 2006, and with exploration success at the Jardim do Ouro prospects, the company has recently appointed NCL Brazil Ltda to undertake a new geological resource and mineral reserve estimate at year-end. Technical and geological information in this report has been read and approved by Serabi's Chief Geologist, Mr Chris Spurway. Mr Spurway BSc (Honours) is a graduate of the University of Sydney in Geology. He is a member of the AusIMM and has worked for over 16 years in mineral exploration including three years in Brazil.

It has a significant history of alluvial gold production with estimated output of some 30 million ounces having been recovered, primarily from artisanal workings. Present in the Tapajos since 1999, Serabi has established the only 'hard rock' mine in the region to date at its Palito gold mine, which produced 39,197 ounces of gold equivalent in 2006 from underground mining of high-grade, gold/copper mineralisation. Serabi has a significant exploration programme focused on the Tapajos region, owns and operates four surface drilling rigs and has its own assay laboratory. ---END OF MESSAGE--- http://hugin.info/137617/R/1152646/221497.jpg http://hugin.info/137617/R/1152646/221498.jpg http://hugin.info/137617/R/1152646/221499.pdf
