The following is a description of the potential size and expected grades of the various deposits on Muirton. Detailed information for calculating definite and accurate ore reserves is not available.

The Deep Structure has not yet been accurately outlined because drilling failed to reach bedrock. However, it k estimated that this structure could be 750 m long and 220 m wide. If it is assumed that the total average thickness of the gravel is 4 m (2.5 m upper gravels and 1.5 m lower gravels) and the relative density of the rock is 2.2, the expected tonnage’s of gravels are:

Trial mining on Muirton was carried out from January to September 1998 using one 14 foot rotary pan plant. During this period the recovery plant was operated only for about 6 months due to a breakdown of the screening plant in June-July. The following results were obtained from the processing of 81 284 tons of gravel:

Abovementioned upper gravels consist of gravels found in the upper layers of the Deep Structure and some material from the Terrace Deposits. The lower gravels were mined from near the base of the Deep Structure.

The 620 carats were sold for R1 300 000 at an average price of R2 096 per carat. The following stones larger than 5 carats were included in this parcel: 70.8, 20.2, 18.6, 17.8, 10.5, 9.7, 8.5, 8.5, 7.86, 7.4, 5.9 and 5.3.
