Havilah Resources Reports On Portia Gold Mine Permitting

Havilah Resources (ASX: HAV) has submitted a revised Program for Environmental Protection and Rehabilitation document for its Portia gold project in South Australia.

This addressed the key issue of disposing excess water generated by dewatering of the Portia open pit with the company proposing to inject the water into the nearby Shylock palaeochannel.

Extensive hydrogeological test work and modelling has demonstrated that its viable under a most likely scenario and that the Shylock palaeochannel could potentially take all excess water from dewatering of the Portia open pit that is not required for processing and other site usage purposes.

Havilah added that while evaporation ponds to achieve the disposal of excess water, it had the disadvantage of a large footprint and potentially increased soil salinity.

This new information was incorporated into the PEPR document, together with additional detail and clarification required on the Project's water management strategy and proposed tailings storage facility design and operation.

The design modifications for the tailings storage facility are likely to save Havilah significant capital expenditure, while eliminating the need for evaporation ponds should considerably reduce rehabilitation costs.

The document submitted to the Department for Manufacturing, Innovation, Trade, Resources and Energy will allow Government regulators to now re-commence regulatory assessment and approval of the Portia project.


Portia has an Inferred Resource of 67,000 ounces of gold with the company having drilled 205 aircore holes.

Mineralisation has been proved over a 600 metre by 100 metre area and ranges from 1 metre to 4 metres thick.
