Highlights:
· A total of 10 out of 55 assays returned grades of over 200 grams per tonne gold ("g/t Au" or "ppm"), with 6 results returning greater than 300 g/t Au and the highest result returning 435 g/t Au;
· Average grade of samples from known underground stoping areas graded between 31-125 g/t Au; and
· Overall average of all samples was 67.3 g/t Au (2.2 ounces/tonne of gold).
"These are encouraging gold grades from the
Update on recent underground sampling at
Overall, the total sample batch of 55 samples collected from the ground beneath the stopes in the Tyn n Cornel section of the Clogau St David's Gold Mine in north
Clogau's gold-bearing lodes are noted for their pockets of high-grade mineralization and historical production concentrated on the pursuit of these high grades zones. Consequently, there has been very little to no work done on material that was previously regarded as waste or where no visible gold was readily apparent.
In order to better evaluate the potential grades from processing larger amounts of remnant material within the mine a "mini-bulk" sampling programme exercise was undertaken during August and
A total 10 x 25kg samples each were selected from each of the underground stoping areas NP, JH, OS, ML, TMP and a additional 5 x 25kg samples were similarly selected from the development drive area within TR.
These sample lots were individually split and 1kg samples taken from each to provide a total of 55 x 1 kg samples. The remaining sample material has been retained and stored for future batch processing through the Company's sample plant.
The full list of assay results are shown in Table 1.

Note: These samples consisting of 1kg of rock were split into 500-gram lots and sent for assay at the ALS Minerals laboratory in Loughrea,
As can be seen from Table 1 all the samples registered gold values with the results continuing to show the high variability to be expected from this type of material recovered from a high-grade gold mine. Values ranged from 0.13g/t from nominal waste material in the Tyn n Cornel development drive to several values over 300g/t Au from the base of the known stoping areas. The notable high values are easily obtained from the presence of fine particulate gold in samples of this size. Overall, the total sample batch average from each area ranged from 4.4g/t to 125g/t Au. The total average for all 55 samples was 67.3g/t Au (2.2 oz/t).
The next stage of the sampling programme will be determine whether there is correlation between these laboratory assay sample results and the original bulk samples by processing them through the Company's pilot plant. It is envisaged these bulk samples will be processed and the Wilfley table used to determine the percentage of gold recoverable by simple gravity separation. The results of these mini-bulk sample tests will be used to more accurately assess and correlate the underground sampling programmes with actual bulk gold recoveries.
