A new hanging-wall zone of strong mineralisation was also discovered, continuing eastwards and at depth in two further drill holes. The new zone remains completely untested further to the east and at depth.

The highly-fractured geological setting of sedimentary rocks within mineralised ironstone around the Tennant Creek area has been the cause of some outstanding discoveries in the past 70 years.

The most notable are Juno, White Devil and Nobles Nob, all of which bear the same signature of being deep, ultra-high-grade deposits covering a relatively small footprint at surface. All of them hosted multi-million-ounce gold lodes.

With the intensity of Bluebird’s copper-gold-bismuth-hematite mineralisation, management believes it to be part of a much bigger system. The 5km gravity corridor within the Barkly tenement includes multiple repeats of Bluebird’s geophysical signature to the east and west and further exploration is underway to test the new targets.

As Tennant integrates its new results with detailed gravity, geochemical and air-core (AC) drilling programs, it appears that Bluebird may hold significant untapped potential. It is hopeful that continued exploration at the site may unlock further high-grade copper-gold resources, which is likely to keep investors on their toes as new results continue to flow.
