The upgrade is scheduled to be finished in early Q4 this year.
The drill campaign began at B4-7, part of the Junior Lake property, in February, aimed at bringing inferred portions of the deposit to indicated status.
In total, 81 diamond holes and four re-entered holes for 15,868 metres, have been completed and assays are pending for 10 holes.
Assays from the eastern part of B4-7 showed massive sulphide mineralisation with grades of more than 1 per cent nickel, plus notable credits of copper, cobalt and platinum group metal.
Notable intersections, not reported previously, included a hole with 1.32 metres at 5.87 per cent zinc, 0.22 per cent nickel, 0.50 per cent copper and 0.04 per cent cobalt.
The results are highly encouraging as they have significantly increased the potential tonnage suitable for open pit mining, the company said.
The B4-7 remains open down dip and along strike to the east and west and is around 3 km to the northwest of the VW deposit.
The combined NI 43-101 resources of the VW and B4-7 deposits to date total 48,281 tonnes of nickel equivalent (NiEq), 82 per cent of which is in the indicated category.
Landore plans to start pre-feasibility studies on the deposits in the first quarter of 2013, and it is currently planning a drilling programme to extend B4-7 to the west, which is due to begin in the fourth quarter of 2012.
