Results of Akrokerri pit definition drilling

GoldStone Resources Limited (AIM: GRL) announces that it has successfully completed its pit definition Reverse Circulation ("RC") drilling programme in the Southern part of the 2012 JORC compliant resource area within the 100% owned Akrokerri licence, with results continuing to confirm the expected gold content.

The RC drilling programme consisted of 26 holes for a total of 1,470 metres at the Akrokerri project.  The programme, which is the first part of the Akrokerri open pit project, identified as AK01 North and AK01 South, confirmed the results of the historical drilling and recent trenching to further support the economic potential of the project.

The preliminary assessment of the RC drilling programme shows that 22 of the 26 holes intersected the mineralised zone with economic values and mining widths for the target zone - Table 1 below shows the results of the intervals that will be used for the Pit design.  The four sub-economic holes (AKRC022, 23, 24 and 26) are situated at the southern end of the proposed southern pit (see Figure 1).  All of the assays were undertaken by the ALS Laboratory in Kumasi, Ghana.

The results from two of the RC infill drillholes exceeded expectations, with AKRC018 returning 2.22g/t over 30 metre drill length between intervals 41 metres and 71 metres at a vertical depth below surface of 27 metres to 48 metres and AKRC012 returning 3.78g/t over 12 metres drill length between intervals 22 metres and 34 metres at a vertical depth below surface of 15 metres to 23 metres.  In addition, hole AKRC017 delivered one of the best results on the Akrokerri licence to date, with 12.4g/t over a 1 metre length between intervals 20 metres and 21 metres at a vertical depth below surface of 13 metres.

Based on these assays from this RC drilling programme,  the arithmetic average of the grades is 1.8 g/t over 10.5 metres drilling width (approximately 7 metres true width) within the mineralised zone of the two proposed pits (sample cut-off 0.5g/t).  The continuous strike length over these two proposed pits is approximately 1,500 metres, compared to the approximately 700 metres strike length of the existing Homase pit which was mined by Ashanti Goldfields between 2002 and 2003 and produced 52,452 oz gold at an average grade of 2.85g/t.

A grade distribution analysis indicates a relatively disseminated pattern, no nugget effect is expected.  Therefore, the grade forecast is expected to be close to the mine grade.

A detailed spatial analysis including an estimation of mineable resources is currently being undertaken using MicroMine software and metallurgical tests are on-going.

This programme has indicated that the mineralisation may split towards the South.  If this is confirmed by 3D analysis, a sub- parallel second zone may be available for mining within the proposed pit.

Bill Trew, Chairman, commented: "We are very pleased that this programme continues to confirm our expectations of the Akrokerri deposit.  We are narrowing the gaps in past drilling and improving the confidence in the resource as required in order to move towards the earliest possible development of a mine.  These results are encouraging, in particular the two infill drillholes that exceeded our expectations and the extent of the near surface oxidised, mineralisation zone.  We look forward to keeping you updated as we seek to move the project forward."
