The central zone extends by a further 150 metres to more than 500 metres while the new zone is parallel and to the east.
It is the third zone in the area as Great Boulder previously identified a parallel zone to the west.
Mineralisation open in all directions
Having three parallel zones enhances the overall metal endowment per vertical metre at Mt Venn, boosting the project’s economic potential.
There is further opportunity to increase value with mineralisation open in all directions.

The company has completed 12 reverse circulation holes for 2,120 metres focused on strike and dip extensions to the central mineralised zone.
It also tested downhole targets along the broader Mt Venn trend.
Core samples have been sent to Perth for analysis with results expected by the third week of January.
The company’s 2017 program has established Mt Venn as a large copper-nickel-cobalt discovery.
2018 exploration plans
Great Boulder plans further drilling in the first quarter of 2018 which will also target the western Mt Venn trend.
Drilling will be undertaken along the entire 4.5 kilometre western magnetic trend.
In the central zone new drilling will focus on up and down dip extensions of known mineralisation and will test strike continuity of the different mineralised zones.
The company will also start a gravity survey over the Mt Venn intrusion early in the new year.
Surface geochemistry and geological mapping will be undertaken in conjunction with the survey to identify intrusions considered more prospective for nickel sulphide mineralisation.
