Serabi Gold plc ("Serabi" or "The Company") Drilling Update Shallow Infill Drilling at Piaui Provides Further Encouragement of Potential
LONDON--(Marketwire - Nov 23, 2011) - Serabi Gold plc (
As previously announced, the Company has been experiencing delays in receiving assay results from the independent laboratory used by the Company, and the preliminary analytical results set out below from infill and extension drilling at the Piaui Prospect have been returned from the Company's own on-site analytical laboratory at the Palito mine (see footnote - Preliminary Assay Results). Shallow infill drilling commenced in October on the promising Piaui propect and 2,600 metres of a shallow diamond drilling programme across 23 drill holes has been recently completed (PDD0495-PDD0501, PDD0503-PDD0517). All samples have also been submitted to ALS Chemex of Vancouver and results of this final analysis will be released in due course.
Mike Hodgson, Chief Executive, commented:
"Piaui represents a previously concealed ore body and as such is unlikely to have been discovered had it not been for our aerial geophysical programme. Previously announced geochemical and drilling results over a 300m strike length indicated good grades at shallow depths including results of1.93 metres @ 22.86g/t Au, 10.7 metres @ 1.17 g/t Au, 9.1 metres @ 2.24 g/t Au, 3.2 metres @ 16.16 g/t Auand4.5 meters @ 2.75 g/t Au,and highlighted the possibility of wider intersections than we have encountered at Palito. The latest preliminary results continue to confirm the potential of Piaui to host broader width near-surface mineralization with good gold grades, over a significant strike length".
The recent drilling follows the successful Phase 1 results together with the highly encouraging results from the ground-based geophysical Induced Polarisation survey undertaken (as announced on 12 September 2011), which indicated that the strike length of the Piaui discovery could now extend up to 1,400 metres. To date, the drilling, which has now been undertaken over two areas of 600 metres and 350 metres within the overall 1,400 metre potential strike length of the prospect, continues to intersect broad zones of intense chlorite/silica/sulfide alteration zones in excess of 40 metres which demonstrate the passage of a significant amount of mineralized fluid. Preliminary on-site analytical results returned to date indicate a very fertile mineralized system, with indications that the system remains open at depth.
Significant preliminary results (subject to confirmation by ALS Chemex) returned to date include:

Note: Assay intercepts are calculated based on a minimum weighted average grade of 0.3g/t Au using a 0.5g/t Au weighted average lower cut and a maximum internal waste interval of 1.2m. All assays were completed by Serabi's on-site laboratory using a 30gm DIBK aqua regia digest with an AAS analysis. Serabi's on-site laboratory is not certificated for analysis and these results should be considered preliminary in nature (please refer to the footnote at the end of this release for further details).
As described above, final analysis has been delayed due to technical issues with the offsite laboratory. Results from a certificated analytical laboratory are expected within the coming months.
The initial Phase 1 drilling programme has now been completed with a total of 8,169 metres having been drilled.
Results have previously been announced for the Piaui, Panhandle and Currutela prospects. Results have now been received from the primary external laboratory in Vancouver, Canada for the samples recovered from the Tatu, Lazaro and Pele prospects which are located north of the Palito deposit. Gold intersections were recovered at Pele and Tatu but the widths and grades are not considered of sufficient interest to warrant further activity at this time given the more encouraging potential of the Piaui, Espeto and Currutela prospects. At the Lazaro prospect, as with the earlier Panhandle prospect, the single drill hole failed to return any indication of a causitve body for the targeted geophysical anomaly.

Quality Assurance and Quality Control Procedures Disclosure
The Company has implemented and maintains a Serabi quality assurance/quality control (QA/QC) protocol at its JDO Project as defined in its "NI 43-101 Technical Report for the Jardim Do Ouro Project, Para State, Brazil" dated 22 December 2010. This ensures best industry practice in sampling and analysis of exploration and resource definition samples. The insertion of field duplicates, certified standards and blank samples into the sample stream form part of the Serabi procedure (these act as an independent check on contamination, precision and accuracy in the analytical laboratory).
Assay results are reported once rigorous QAQC procedures have been approved.
Preliminary Assay Results
The assay results reported in the table within this release are those provided by the Company's own on-site laboratory facilities and have not yet been independently verified although the Company has already despatched duplicate samples for such verification using fire assay methodology. Serabi closely monitors the performance of its own facility against results from independent laboratory analysis for quality control purposes. In 2008 NCL(Brasil) Ltda, the author of the Company's independent technical reports produced in compliance with Canadian National Instrument 43-101 reviewed and compared over 1,000 sample results of the Palito laboratory against results obtained by an independent laboratory using fire assay. They noted that when discarding from the sample population all results of less than 0.7g/t "the repeatability improves significantly reaching the generally accepted limits of variance (90% of the samples with HARD < 20%)". Further details are set out in their report NI 43.101 TECHNICAL REPORT FOR THE JARDIM DO OURO PROJECT, PARA STATE, BRAZIL dated December 9, 2010 and available on the Company's website.
During 2011 the Company has continued to monitor the performance of its own laboratory against results reported by the Company's independent laboratory and have concluded that by eliminating from its sample population all results of less than 0.3 g/t there remains good correlation and for higher grade gold values the tendency is for the Company's own results to be under-reported due to the improved gold recovery that can be obtained using fire assay methods.
The Company would expect that in the preparation of any future independent Reserve/Resource statement undertaken in compliance with a recognised standard, the independent authors of such a statement would not use Preliminary assay results but would only use assay results reported by an appropriately certificated laboratory.
