TAGOU PROJECT
Geochemical Soil Sampling
==> picture [65 x 104] intentionally omitted <==
At Tagou 4,705 soil geochemical samples were collected at 400 metre x 100 metre centres over areas not previously sampled, resulting in coverage over the entire project area. All assay results have now been received and numerous strong gold-in-soil anomalies have been identified.
In many instances the anomalies are coincident with significant interpreted underlying structures and in the central portion of the

Permit a broad 15 kilometre x 7 kilometre zone is characterised by elevated gold-in-soil geochemistry, representing a key focus for follow-up gold exploration including geophysical surveys and drilling.
The most significant results include 2,950ppb Au, 450ppb Au, 416ppb Au, 229ppb Au, 180ppb Au, 175ppb Au, 162ppb Au and 116ppb Au (see Figure 1) .

RC Drilling
In June 2012 the Company secured a RC rig to drill 16 reconnaissance holes for 1,826 metres to test the width and tenor of near-surface gold-bearing quartz veins which were identified by past and present artisanal mining sites.
All assay results have now been received from the programme and 8 of 10 holes that targeted veins on the southern zone intersected gold mineralisation within granite or dolerite hosted quartz vein or veins.
Best results include 4m @ 2.60 g/t Au from 49m in TGRC011 (including 1m @ 9.79 g/t Au) , 11m @ 0.84 g/t Au from 28m in TGRC010 (including 2m @ 2.00 g/t Au) and 2m @ 2.44 g/t Au from 90m in TGRC009 (see Figure 2, Table 1) .

The drilling results highlight the spotty or nuggety nature of gold which exists in the northsouth trending quartz veins. It is encouraging to note that gold mineralisation has been shown to continue to depths of at least 100 metres in the veins and in low grade mineralised envelopes, as highlighted in the drilling intercept of 0.84 g/t Au over a width of 11 metres.
Since the completion of the drilling programme, results from geochemical sampling over the entire Tagou Project area have been received and the interpretation of all of the geochemical sampling and drilling results indicates that the preferred northeast-southwest structural trend (which has not yet been drilled) holds the best potential to yield gold mineralisation over significant widths. Several strong geochemical anomalies, which may reflect this preferred structural trend, have been identified and these anomalies will be further defined by mapping and magnetic survey work prior to drill testing.
KERI PROJECT
Geochemical Soil Sampling
Soil geochemical sampling at the Keri Project targeted 1,182 sample sites, although the programme was only partly completed by the end of June due to the onset of seasonal rains. The programme focused on the western half of the Permit which covers a NNE-SSW trending structural corridor and greenstone rock sequence.
Samples were collected at 100 metre intervals along east-west lines spaced 400 metres apart.
Numerous significant gold-in-soil geochemical anomalies were discovered (see Figure 3) , including a 1.8 kilometre long anomaly peaking at 159 ppb Au which is coincident with a gabbro–felsic volcanic contact in the north-western portion of the sample area. The anomaly is also coincident with an interpreted demagnetised zone that appears to be related to a significant structural jog in a regional structure.

MOAGA PROJECT
Geochemical Soil Sampling
A soil geochemical sampling programme was completed at the Moaga Project, comprising 436 sample locations over a NNE-SSW trending structural corridor which traverses the midwest part of the Permit.
Samples were collected at 100 metre intervals along east-west lines spaced 400 metres apart.
All assay results have now been received with numerous anomalous results, including 74 ppb Au and 41ppb Au, being returned from the central part of the sampled area (see Figure 3) . The sampling programme will be expanded into other parts of the Permit following the wet season.

Soil Geochemical sampling and assaying methodology
First pass soil sampling has been completed on 100 metre intervals on east-west oriented lines, spaced at 400 metres. A 100-200 gram sample is collected from the “B horizon” at approximately 10 centimetres depth at each sample location and sieved using a 10 mesh sieve. This sample is then placed into wet strength bags. Standards are inserted into the sample stream at a rate of 1 in 20 samples and field repeats are collected at a rate of 1 in 40 samples.
Samples are despatched to the ALS Global Laboratory in Perth, Western Australia and analysed for gold. The entire sample is pulverised to 85% passing 75 micron or better and split using a riffle splitter. A 25 gram sample is analysed for gold by method Au-TL43m which includes an Aqua Regia extraction with ICP-MS finish. Reporting limits are between 0.001 and 1.0ppm Au.
RC drilling sampling and assaying methodology
Samples are collected as four metre spear composite samples as well as single metre riffle split samples, when identified as geologically significant. All significant results reported are from single metre split samples. Standards are inserted into the sample stream at a rate of 1 in 40 samples and duplicates are also collected at a rate of 1 in 40 samples (alternating with the standards so a standard or duplicate is used every 20 samples). Samples are submitted to the ALS Global Laboratory in Ouagadougou, Burkina Faso and assayed for gold using method AuAA26. The entire sample is pulverised to 85% passing 75 micron or better, then split so that 50 grams of sample material can be collected for assay by fire assay with an AAS finish.
