Even big finds have to start somewhere and Kingfisher Mining’s (ASX:KFM) ongoing regional mapping and rock chipping program at its Bootaloo project in Western Australia’s Ashburton Basin, has already returned some intriguing results.

Rock chip assay results of up to 37.8% copper and 2.57 grams per tonne (g/t) gold have identified two new areas of high-grade copper and associated gold mineralisation.

This is early validation of the company’s goal of building its understanding of the regional geology and mineralisation potential within an emerging copper province.

Diamond drilling completed earlier this year had already intersected multiple zones of mineralisation at the Copper Strike prospect, including a broad zone of 16m of disseminated copper sulphides.

Kingfisher plans to carry out a 5,000m reverse circulation program in August that will be guided by existing targets and results from the airborne electromagnetic survey that was carried out last month.

Further to the east, Rincon Resources (ASX:RCR) expects to kick off a maiden 5,000m RC drill program in mid-July at the Hasties prospect within the South Telfer gold-copper project in the Paterson Province.

This program will test an interpreted south-eastern plunge to existing mineralisation and validate zones of gold and copper mineralisation.

Historical drilling revealed mineralisation intersects such as 57.8m grading 2.05g/t gold from a depth of 17.4m, 16.1m at 4.75g/t gold from 42.7m, and 10.9m at 3.39% copper from 91.8m.

Preliminary interpretation of a recently completed induced polarisation survey had highlighted new targets, and a deeper target below the existing mineralised zone.

Induced polarisation is geophysical imaging technique that uses electrical currents to provide additional information about underground rock formations.

The company will also shortly start soil sampling at the Westin prospect that in conjunction with electromagnetic work, enhance target generation in those tenements.

Underexplored gold ground

Westar Resources (ASX:WSR) is preparing to start maiden RC drilling at its Winjangoo project near Mount Magnet to test several priority drill targets within a broad mineralisation corridor identified from geochemical auger sampling.

Despite its proximity to the historical mining centre at Mount Magnet that has produced over 6 million ounces of gold since the initial discovery in 1891, there has been little exploration on Winjagoo.

Historical exploration at the project is limited to minor geochemical programs, desktop studies, regional geophysical programs, and geological mapping over limited portions of the project area.

Since acquiring the project, Westar has completed regional reconnaissance and field mapping, airborne geophysical survey, an auger soil geochemical program and target generation.

It will now drill holes up to a depth of 80m with the flexibility to extend holes if prospective geology or indicators of mineralisation are intersected during drilling.

The program also includes several priority 2 holes that can be immediately drilled pending success of the priority 1 holes.
