North Portia Infill Drilling Results
North Portia Infill Drilling Results
Adelaide, Nov 28, 2017 AEST (ABN Newswire) - Havilah Resources Limited (ASX:HAV) (Havilah) has recently completed a further round of drilling at the North Portia Copper-Gold deposit (North Portia), comprising 23 aircore holes for a total 2,662 metres.


- Infill resource drilling at North Portia continues to confirm economic copper grades.

- New drilling results will be incorporated into an updated resource model.

- Resource model to guide mining design for PFS.

Better results include:

All holes were drilled into the upper secondary enriched zone of the deposit above approximately 140 metres depth with the objective of better defining this part of the resource in order to improve confidence in the resource model. Other holes, not reported here, were also targeted in peripheral areas of the deposit to more accurately define the limits of economic mineralisation and generally returned low to subeconomic grades as expected.

This new drilling data will now be incorporated into a revised resource block model that will be used in mine planning and mine design studies as part of the prefeasibility study (PFS) that is presently being jointly conducted with Consolidated Mining and Civil Pty Ltd (CMC), Havilah's mining partner at the Portia Gold Mine (Portia) (refer to ASX announcement 22 November 2017).

Commenting on the latest North Portia drilling results, Havilah's CEO, Mr Walter Richards said: "This drilling program has added more important data that confirms the encouraging grades of copper and gold in the upper, secondary enriched part of the North Portia resource.

"It is Havilah's obligation under the North Portia MOU to fund and deliver an independently verified JORC Measured and Indicated Resource for North Portia, and these results will help us to deliver that outcome.

"This is another positive step in the implementation of our Copper Growth Strategy", he said.

About North Portia and the MOU with CMC

North Portia contains a JORC Indicated and Inferred Resource estimate of 11.3 million tonnes of 0.89% Cu, 0.64 g/t Au and 500 ppm Mo (refer to ASX announcement of 24 November 2010 and table attached). Havilah's recent drilling, and the immediate focus of the MOU work, is a secondary (supergene) enriched zone of copper and gold mineralisation in saprolite material above approximately 150 metres depth. This drilling has clearly delineated a gold enriched cap that sits on top of the underlying secondary and primary copper sulphide mineralisation, which can be processed in the existing Portia gold plant, with some upgrades to recover the finer free gold that is present.

Under the terms of the North Portia MOU, CMC will have an exclusive option until 30 June 2018 to enter into a development agreement for North Portia on terms to be agreed. During the exclusive option period, CMC and Havilah have agreed on a shared work program that is designed to provide the key information to assist CMC and Havilah to determine a mutually acceptable arrangement that will lead to the development of North Portia. This work will include completion of a PFS and securing permitting to commence overburden removal by July 2018. The initial mining target will be approximately 5 million tonnes of free digging secondary saprolite gold and copper-gold material above 150 metres depth. It is expected that all of this material will be able to be processed in the Portia processing plant, with the addition of a flotation circuit to recover the finer free gold and the copper sulphides.
