The conceptual estimate follows a recently completed 26-hole diamond drilling programme.

Under the parameters of the estimate, which has not been completed to JORC standards, the conceptual grade tonnage at Star could amount to 485,000 tonnes of ore grading 15.4% zinc.
The conceptual analysis suggests a core of high grade massive willemite material in both the east and west limbs of the deposit.
There’s also further exploration potential to extend mineralisation to the east-north-east and south-east, which remain open-ended.
"This result is very pleasing in as much as it substantiates our initial prognosis for acquiring a majority interest in the project,” said chief executive Colin Bird.
“The study has demonstrated two quite distinct mineralisation types which potentially could lead to significant increases in tonnage of material with zinc-grade in excess of cut-off. The areas to the east and south-east of the mineralised domain remain open with good geophysics and geochemical signatures identified. The company intends to test the prognosis for a deeper feeder source for the mineralisation but prior to this it will research this further, which to a large degree will be led by the current programme evaluation and further drill results."
