Legend Mining (ASX:LEG) commenced aircore drilling over the weekend targeting nickel-copper mineralisation at its Rockford Project in the Fraser Range of Western Australia.

The drilling program will comprise 65 holes for ~5,000 metres and concentrate on multiple targets at Area D and the immediate surrounds.

The exploration focus has returned to Area D following a full review of petrology results from diamond drilling completed in July 2016.

The review revealed positive factors and indicate that Area D could potentially be in a favourable environment for nickel-copper mineralisation. 

Drilling is estimated to take 3-4 weeks to complete with assay results expected 4 weeks later.

Previous exploration at Area D

Previous exploration at Area D involved extensive moving and fixed loop electromagnetic (EM) surveying with eight conductors (D1-D8) identified.

Seven of these conductors were tested with reverse circulation and diamond drilling.

This work covered an area of 3x2 kilometres centred around a discrete gravity high.

The proposed aircore programme will extend the coverage to an area of 7x5 kilometres and test several aeromagnetic lows and highs, as well as the flanks of the gravity high.

Objectives of the drilling

The drilling will provide valuable information on Area D’s geology and how the rock profiles change with depth.

It will also provide data to enable selection and prioritisation of areas for the next phase of high power EM surveys.

The Fraser Range hosts the world-class Nova-Bollinger discovery

The Rockford project is located in the globally renowned Fraser Range district of Western Australia and covers an area of 2,792 square kilometres.

The Fraser Range is host to the nickel-copper sulphide Nova-Bollinger deposit.

Rockford covers a strike length of 100 kilometres over a regional gravity high ridge associated with dense mafic/ultramafic intrusive rocks of the Fraser Zone.

The Nova-Bollinger deposit, which lies within the Fraser Zone, is situated on a similar tenor gravity ridge to that of the Rockford project.
