Castillo's halo effect

DRILLING by Castillo Copper at the historic Cangai copper mine in New South Wales’ New England Fold Belt has delivered a new zone of massive sulphides between the Sellars and Volkhardts lodes, with the best hole intersecting 30m of mineralisation.

Castillo executive director Alan Armstrong said the company appeared to be on the right track in its goal of re-opening the mine, which was shuttered in 1917.

The sulphides have been seen in seven of eight holes drilled to date, supporting the theory that the halo between the lodes is mineralised disseminated and breccia sulphides on the outer zones to semi-massive/massive veins within the core of the shear zone.

Following a recent fixed loop electro-magnetic survey Castillo expanded its drilling plan to 18 holes to not only test the location of the historic workings and identify the extent of mineralisation within the resource shells, but also to examine the halo potential and test up to five anomalies beneath and external to the line of lode.
