A recent drilling program at the Bluebird discovery at Tennant Minerals’ Barkly Project has intersected further thick, high-grade copper and gold zones, including silver.
In addition to identifying new copper and gold zones that expand resource potential to the east, west and at depth within the Bluebird ironstone corridor, the results identified a new well-mineralised zone of copper-gold mineralisation at Bluebird East that is thickening with depth and demonstrates significant expansion potential.
Up to four large, high-grade copper-gold lenses – each up to 300m in length and 200m deep – were also identified from updated interpretation of the mineralisation at Bluebird.
The results from a series of step-out RC holes within the 2.5km strike-length Bluebird-Perseverance trend are pending. These results will be integrated with detailed gravity, auger geochemistry and air-core drilling programs in progress to define new priority targets for Bluebird repeats within this zone.
Tennant Minerals’ CEO, Vincent Algar, said that the latest assay results from Bluebird not only confirmed the high gold and copper grades from previous drilling programs but have also extended the mineralised zones to the east and down-plunge to the west of previous drilling.
“One of the most exciting outcomes of the program has been the identification that Bluebird is made up of up to four large, high-grade copper/gold mineralised lenses within the east-west trending ironstone-host at Bluebird – which remain completely open to the east and west.
“New intersections associated with the host ironstone lithology have extended the mineralisation at depth and westwards down-plunge.
“The new drilling has also identified a new hanging-wall zone of thick, strong mineralisation which continues eastwards and to depth. This new zone is completely untested further eastwards and at depth within the host ironstone corridor.”
Mr Algar said the high intensity of the Bluebird copper-gold-bismuth-hematite mineralisation has always suggested it is part of a much larger system.
“The greater than 5km strike-length gravity corridor within the Barkly tenement includes multiple repeats of the Bluebird geophysical signature, and further work is underway to define and test targets for new discoveries.
“The latest results reinforce our confidence in defining economic copper-gold resources within the Barkly project, in line with our goal to become a major player in the rejuvenated Tennant Creek Mineral Field, which has already produced 5.5Moz of gold and 700kt of copper.”
