Key Points

  • Company reports massive sulphides in latest 30m drill core pulled from nearby the known Bluebird prospect mineralisation
  • Company now targeting this area further in the hopes it can post a multi-million tonne copper-gold resource
  • Second drill rig mobilised on-site to carry out further drilling to test copper-gold targets

Tennant Minerals (ASX: TMS) has intersected a new massive copper sulphide at the 5km long Bluebird prospect within the larger Barkly project in the Northern Territory. 

The drill hole intersected a 7m core with a concentration of some 60% massive sulphides, which was part of a larger 32.5m drill core pulled from a geological hematite-copper mineralised zone. 

While assay results have not yet been returned, the company highlights its previous drill results in supporting today’s new find. 

Note on previous grades 

Investor information provider Undervalued Equity notes high-grade gold is that in concentrations over 5 grams of gold per tonne of ore (5g/t), whereas copper is considered high-grade in concentrations over 1.5%

Compare that to the previous results highlighted today:

  • 63m @ 2.1% copper and 4.6g/t gold from 153m depth 

  • 40m @ 2.6% copper and 1.3g/t gold from 131m depth 

Further drilling to target area 

The location from which Tennant today reports its 32m drill core with a 7m section of massive sulphides will now be the subject of more drilling by Tennant as the company seeks to find more prospective acreage at Barkly to expand the scope of operations. 

A current drill run using the second rig on site is targeting a deeper extension of the Bluebird discovery with the deepest intersection yet at 277m depth and returning 3.7% copper, well over the high grade threshold, but lower gold reads at 0.34g/t gold.

The company is hopeful it can find a second high-grade zone, which would give the company the potential to publish a multi-million tonne gold resource.
