Summary and Assessment of Results

Satellite and Aerial surveying was used, followed up by on-ground surveys delineated prospective ground. A nine inch drilling rig was then used to test the selected sites.

Test drilling took place in year one and year four of the EPM only. This was due to Covid and illness related hold ups.

The total number of nine inch diameter exploration holes drilled on the EP is two hundred and thirty seven.

The total feet drilled is eleven thousand one hundred and ninety.

Test drilling revealed that the ground composition most of the identified targets on the EPM area is unsuitable for the deposition of opal.

Test drilling also identified several target areas of interest with suitable ground conditions for opal deposition, more specifically sand stone deposits layers, some containing opal trace deposits.

In summary, test drilling has only revealed opal trace, and not commercially viable opal deposits.
