The work was funded by OZ Minerals, which is spending A$1 million on exploration to earn 51% of the 300 sq km project. Avrupa is the operator of the programme. The work comprised 18 holes in eight separate targets but most of the drilling was in the Entre Matinhas area.
Here, copper values in six of eight holes came in at 0.1% and greater over intervals of between 1.5 meters and 86 meters. A highlight was 2.55 meters at 0.91% copper in one hole.
In another target area, the group found 4.7 meters at 0.13% copper in another hole.
Avrupa noted that the first-pass drilling programme covered only a limited area at shallow depths, yet the results "clearly demonstrate real, close-to-surface potential for IOCG mineralisation in a well-defined, easily prospectable target area".
CEO and president at the firm Paul Kuhn said: "We are excited that the initial work shows significant IOCG mineralization potential in a select and specific target area on the Alvito project.
"Our work around the property indicates that there are more target areas of interest, however, we have made an excellent start by defining the general Entre Matinhas target as the first priority for further exploration."
Further IOCG-style mineralization and alteration are present in the Manisela target area, north of Entre Matinhas, and at Entre as Matas, northeast of Entre Matinhas.
Meanwhile, first-pass geological mapping and ground geophysics suggest that the area to the west of Entre Matinhas and Manisela may also host IOCG possibilities in the Vale da Rata, Nogueira, Vale Nogueira, and 1440 target areas said Avrupa.
