The Muirton property has considerable potential for the recovery of high quality gem diamonds, the main target being the Deep Structure. The following is a summary of the estimated tonnages and expected grades or the various deposits.

It is important that these potential deposits are properly investigated before commencing with commercial mining. The following prospecting work is recommended:

A detailed programme of reverse circulation drilling to accurately outline the gravel deposit and with the emphasis on investigating the lower gravels. Normal percussion drilling should not be used on such a relatively deep deposit that contains unconsolidated sand within the gravel sequence.

Terrace Deposits:

Percussion drilling to fully examine the extent and nature of these gravels on the farm. More attention should also be given to the zone immediately west of the Vaal River.

The strong linear magnetic feature occurring along the eastern part of the property could be an indication of the presence or a kimberlite fissure with possible blows. Inclined diamond (core) drilling will be required to properly investigate this possibility. It is recommended that an initial drilling programme should consist of three 75 metre inclined boreholes.
