Rox managing director, Ian Mulholland said, "we intend to start drilling this week."
Five of eight loops have been completed and the remainder of the program expected to be completed within the next fortnight.
Mulholland said, "The initial results from the EM survey loops that have been completed so far are highly encouraging."
"The strong EM conductors at Camelwood, Corktree and Silverbark have all been confirmed. We will know more once the EM survey has been completed and the report finalised.
In December, Rox discovered sulphide mineralisation coincident with electromagnetic conductors through reverse circulation drilling on the Fisher East nickel prospect
In January, drilling results produced generally higher grade and thicker nickel intercepts than previously logged, with widths of up to 20 metres and grades up to 3% nickel.
The prospect forms part of the Mt Fisher Project, 450 kilometres north of Kalgoorlie.
Reverse circulation drilling returned a thick intersection of 20 metres at 1.1% nickel from 159 metres, including 6 metres at 1.4% nickel and 5 metres at 1.5% nickel.
