TAW - Tawana Resources NL - Robust Geochemical anomalies defined at Nimba and Lofa Projects, Liberia, West Africa Tawana Resources NL (Incorporated in Australia) (Registration number ACN 085 166 721) Share code on the JSE Limited: TAW ISIN: AU000000TAW7 Share code on the Australian Stock Exchange Limited: TAW ISIN: AU000000TAW7 ("Tawana" or "the Company") Robust Geochemical Anomalies Defined at Nimba and Lofa Projects, Liberia, West Africa (Please note all maps and images have been removed and can be found on the Tawana website) HIGHLIGHTS * High priority stream sediment gold anomalies defined at the Nimba and Lofa projects * Large scale robust 10 km strike length target identified at Nimba and 6 km strike length target at Lofa * Anomalous target areas enhanced by coincident artisanal workings, favourable geology and major structures that host the 5 Moz Ity mine and 1.52 Moz New Liberty resource * Field teams in place for immediate follow-up in the New Year Tawana Resources NL (ASX: TAW, the `Company`) is pleased to announce it has identified several high priority stream sediment anomalies from its maiden geological exploration program on the companies Nimba and Lofa projects in Liberia, West Africa. Tawana Resource NL, Managing director, Len Kolff said "This is a great result for the Nimba and Lofa licences acquired under the Gryphon Strategic Alliance; discrete target areas have been identified by robust, stream sediment geochemical anomalies that will be immediately followed up with soil sampling & drill targeting." Nimba BLEG Anomalies A total of 355 stream sediment samples were collected on the Nimba prospect of which 154 samples were selected for BLEG gold and multi-element geochemical analysis. Clustering of gold anomalies was observed in the south of the tenement area. In addition gold anomalies were scrutinised and ranked by evaluating their multi- element geochemical signatures based on relative metal concentrations. Clear multi-element geochemical signatures (Au+Ba+Ga/La+Pb and Au+Cu+Fe+Pb+Ti+V) were observed with peak gold anomalism, providing confidence that the stream sediments are substantially sampling the bedrock and that the gold anomalies are genuine. Peak anomalies were recorded at 16ppb; 16 times higher than background gold levels of around 1ppb. These factors combined provide confidence that results are robust and defining anomalism associated with upstream gold mineralisation. The strongest gold response in the SW corner of Nimba is defining a +10km strike length ridge and two smaller sub-parallel ridges on either side of the main trend. These target areas are further enhanced by increased artisanal mining activity downstream, coincident topographic and magnetic highs and favourable structural and lithological settings. Lofa BLEG Anomalies A total of 218 stream sediment samples were collected on the Lofa license of which 74 samples were selected for BLEG gold and multi-element geochemical analysis. Peak gold anomalism was reported at 8.6ppb; 8.5 times higher than background gold levels of around 1ppb. Clustering of anomalies was observed within streams draining a discrete 6x3 km area of hills in the north-west of the tenement area. Anomalies were scrutinised further and multi-element geochemical signatures defined, with the strongest gold response associated with a Au+Ba+Ga/La+Pb signature as per Nimba in addition to a Cu-Ni-Cr-V-Ti-Fe metal association suggesting a mafic/ultramafic lithological host. Ultramafics have not been recorded on the government USGS regional geological map; however, native Cu mineral occurrences are recorded on the northern licence boundary immediately adjacent, further supporting and enhancing the anomalous area. Sampling and Assay Methodology Stream sediment samples were collected using an ultra-sensitive Bulk Leach Extractable Gold (BLEG) methodology which is designed to minimise "nugget effect" sampling issues and increase sample result repeatability. The BLEG methodology used is specifically designed to see mineralisation signatures from large hydrothermal gold systems whilst filtering out the effects of small, high-grade systems that can generate costly and time consuming false anomalies. It is highly appropriate in tropical environments where there has been long lived deep weathering and erosion creating significant dispersion trains. All samples were submitted to OMAC Stewart Group laboratory for gold and multi-element geochemical analysis. Gold analysis was by low level BLEG using accelerated active leach with leach aid (DL 0.1ppb) and multi-element geochemical analysis was by Aqua Regia digest and combined Inductively Coupled Plasma with Atomic Emission Spectrometry or Mass Spectrometry (ICPAES/MS) finish. Results received have passed internal and external QA/QC procedures and are within reporting error limits (+/-2SD) of certified standards inserted by the Company providing confidence in reported results. Next Steps and Timing A soil sampling and infill stream sediments programme has been planned to cover the newly identified target areas. Field work is expected to commence early in the New Year. Pending results, infill soil sampling and trenching followed by drilling of subsequent target areas is planned. About Liberia Liberia is a democratic country run by Her Excellency President Ellen Johnson-Sirleaf; Africa`s first elected female head of state in 2005. The country is hugely prospective and hosts several world class iron ore deposits but yet is completely underexplored for gold and non-ferrous metals. Liberia has a modern and transparent mining code and the government is supportive of foreign investment especially in the exploration and mining industry to help unlock the value of its potential mineral wealth. Tawana is one of the first ASX listed junior companies into Liberia following in the footsteps of mining majors BHPBilliton, Arcelor-Mittal and Severstal. Liberia is located in West Africa dominantly within the Archean aged Kenema Man Domain and lesser Birimian sediments to the east. There are a large number of world class mineral deposits located in the Archean and Birimian rock types throughout West Africa including Obuasi (+40 Moz) and Tasiast (+18 Moz). West Africa is one of the fastest growing mineral provinces in the world and Liberia currently hosts several world class iron ore deposits and is underexplored for gold.
