Twenty Seven begins drilling at Rover, AEM survey identifies numerous additional targets
Twenty Seven will expand on the shallow high-grade Creasy 1 gold discovery at Rover.
Twenty Seven (ASX: TSC) has begun a reverse circulation drilling campaign at its Rover project in Western Australia’s goldfields, with the company also reporting an airborne electromagnetic survey had identified 13 conductors at the project.
The drilling program is expected to take three to four weeks to complete and will comprise about 2,000m.
Twenty Seven hopes the program will expand on the previous shallow high-grade discovery at the Creasy 1 prospect, which had returned 4m at 4.3 grams per tonne gold, including 1m at 51g/t gold; and 5m at 9g/t gold, including 1m at 44.1g/t gold.
The company’s chief executive officer Ian Warland said expanding on the Creasy 1 discovery was the focus of the current campaign, as well as testing the volcanogenic massive sulphide potential at the Harmonic prospect.
At Harmonic, the gold intercepts were linked to base metals.
Previous drilling at the prospect uncovered 14m at 1g/t gold, including 2m at 3.3g/t gold and 21.2g/t gold from 26m; and 9m at 1.4g/t gold, including 1m at 7.25g/t gold from 58m.
Airborne electromagnetic survey results
In addition to kicking off drilling, Twenty Seven revealed a recent airborne electromagnetic survey had returned “encouraging” results, including 13 conductors along 20km of strike.
Two of the conductors were noted at Creasy 2 where drilling intercepted 24m at 1,825 parts per million zinc from surface and 6m at 2,210ppm zinc from 33m.
A 3m composited sample yielded up to 3,020ppm zinc.
Mr Warland said the survey results were an “exciting development” for the company – generating a pipeline of prospective gold and VMS-style targets.
“As the geology team is at site for the start of the upcoming reverse circulation drilling campaign, we have taken the opportunity to reconcile the airborne electromagnetic survey results with field observations to formulate which targets are to be prioritised for drill testing.”
“We look forward to reporting further developments as they materialise,” he added.
