Legend Mining Limited (ASX:LEG) is encouraged by the discovery of two new base metals prospects within the Rockford project on Western Australia’s highly prospective Fraser Range.
The company’s ongoing systematic aircore drilling and geophysics across its large Fraser Range landholding has revealed the Crean and Worsley prospects in the Rockford South area.
Rockford is in the same area in which Independence Group (ASX:IGO) has been so successful with its Nova-Bollinger operations and subsequent Andromeda discovery.
Legend’s managing director Mark Wilson told Proactive Investors that the Crean prospect “is something that those who watch the company are very familiar with”.
He said: “It is a nickel-copper-cobalt story, similar to what is at Nova and Mark Creasy’s Silver Knight deposit and what we are hoping to flesh out at Area D, which remains our number one target.”
At Crean, broad anomalous nickel intervals were returned in two holes:
- 28 metres at 0.17% nickel, 0.02% copper and 0.03% cobalt from 16 metres; and
- 34 metres at 0.19% nickel, 0.01% copper and 0.03% cobalt from 20 metres.
Copper-zinc-gold VMS-style prospect
Wilson said Worsley was a copper-zinc-gold VMS-style prospect, “the implications of which are probably more understood by industry ‘tech-heads’.
“There are some very strong indicator and pathfinder elements in that core consistent with VMS.”
A previous hole at Worsley intersected a profile containing 49 metres of ferruginous saprolilte before ending at 97 metres in banded mafic granulite with elevated copper-zinc-silver and trace amounts of pyrite.
It returned an intersection of 9 metres at 0.09% copper, 0.06% zinc and 1.47 g/t silver from 88 metres to the end of the hole.

A new hole drilled 100 metres to the east of this hole has defined coherent metal zoning including 12 metres at 0.09% copper, overlying 20 metres at 0.11% zinc.
Wilson said: “When you look at the assays, there is virtually a Periodic Table of Elements in there.
“You really do need to know your onions to know that 20 metres of 0.11% zinc is potentially quite significant.
“We believe that our nearby Shackleton prospect is also VMS, as is the nearby Andromeda discovery of Independence.”
Explorer theme for names
Wilson explained that the company had adopted a ‘legendary explorer’ theme with naming of its tenements with Shackleton, Crean and Worsley being intrepid Antarctic explorers.
He said that Crean and Worsley were the result of the company’s “systematic work bearing fruit”.
“This whole Rockford area is soil covered and all we can do is go systematically about aircore drilling and doing geophysics to try and find things of interest,” he added.
