Namibian explorer Avonlea Minerals has seen its inferred resource estimate at the Ondjou project increase by 33% to 693 million tonnes of iron ore at a head grade 23.7%. The increase in the company’s inferred JORC resource has been drawn from a recently completed diamond core drilling programme and metallurgical test results. A report by independent consultant Golder Associates confirmed these results.

Avonlea has commissioned a conceptual mine planning study for the Ondjou magnetite iron project in northern Namibia to review the potential mine plan and pit design that could be achieved with the current upgraded inferred JORC geological resource. The study will consider the optimisation of the current resource within a framework of mining, processing and production rates and costs to define potential mining pit shells using the Whittle mining software package.

The explorer had a number of licences in application over the same geological formation to the north and south of the Ondjou prospect. Once granted it intends to operate to unlock the prospectivity of the licence areas using the same exploration methods it has previously applied with success.
