Mineral Resources and Reserves for Petmin’s operations are reported in accordance with the requirements of the South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC).
The Mineral Resources and Reserves reported for Samquarz are based on information compiled by SRK Consulting (South Africa) (Pty) Ltd, which was published in the Competent Person’s Report on 1 October 2008.
| Resource classification | Quartzite* (Mt) | Chert** (Mt) |

| Inferred | - | 48.31 |
| Total Resources | 80.60 | 59.79 |
| * | The estimated quartzite Mineral Resource was divided as follows: |
| Measured: | total resource within the base case pit outline. |
| Indicated: | balance of the resource outside the base case pit outline. |
| Inferred: | there are no Inferred Resources. |
| ** | The estimated Mineral Resource for chert and chert products was divided as follows: |
| Measured: | estimated resource of chert and chert products within years one to 20 in base case pit outline. |
| Indicated: | balance of the estimated resource from year 21 onward. |
| Inferred: | balance of the estimated resource lying outside the base case pit limits. |

The 2007 Mineral Reserve estimates presented in the table above are based on an updated CPR by SRK, as published in October 2008, and are in accordance with the SAMREC code 2007. The estimated depletion of reserves due to mining operations from the dates of the previous CPRs has not been independently verified.

Snowden Mining Industry Consultants published a resource statement in February 2008 prior to the acquisition of Veremo by Kermas and Petmin. This data is currently being validated and the extent and quality of the Veremo resources will be finalised in the first quarter of 2010.
