DHTEM results for East Trough have also been returned with multiple conductive plates modelled and follow-up being planned.

Lunnon Metals is set to carry out reverse circulation drilling within the East Cooee area next week, which includes the ECO-H/W and East Trough prospects at the Kambalda Nickel Project in Western Australia’s Eastern Goldfields.

Drill spacing once the infill drilling is complete will be better than 40m x 40m and is expected to result in an initial mineral resource estimation.

Recently reported intersections such as 9m at 1.66% nickel from 113m, including 1m at 7.44pc nickel from 113m will be followed up.

A diamond hole at the ECO – H/W prospect will also be completed as part of the program to provide metallurgical and litho-structural data.

Lunnon (ASX:LM8) says the prospect presents a shallow, easily accessible potential source of high-grade nickel sulphides with further upside nearby at East Trough.

Goal to move straight into mineral resource

Lunnon managing director Ed Ainscough said it was “great to have the RC rig back to get straight on to this shallow opportunity”.

“The goal is to turn this around as quickly as possible, hence the 40m x 40m drill spacing, which will position us to move straight into a mineral resource exercise if the positive results continue.

“That milestone and the developing opportunity on East Trough means East Cooee continues to be a top priority.”

East Trough DHTEM survey

As previously reported, Lunnon intersected 2m at 5.07% nickel in ECO21RC_005 on an interpreted embayment in the East Trough.

The East Trough is located just 300–400m to the immediate southwest of ECO-H/W and the RC infill drilling program about to start.

The initial down hole transient electro-magnetic (DHTEM) survey in October failed to reach target depth and so a deeper diamond drill hole was drilled and surveyed in the footwall of the interpreted trough to attempt to detect the presence of nickel sulphides to the west of ECO21RC_005.

DHTEM results

Results have now been received along with analysis by the geophysical consultants.

Two modest sized conductive plates (A & B), modelled in the immediate vicinity of the nickel intersected in ECO21RC_005, are aligned along the interpreted trough and are believed to represent pods of massive nickel sulphides in between RC holes ECO21RC_005 and ECO21RC_003.

A larger conductive plate (C) was modelled to the east and is interpreted to represent nickel mineralisation that was recorded higher up in the same ECO21RC_005 hole (1m at 1.11% nickel) and CD 587 (2.25m at 3.37% nickel).

This plate extends to the east at least 50m at a gentle dip and extends 225m up and down plunge.

Next steps

The outcome of the RC infill programme at ECO-H/W will be reported once all results are returned.

At East Trough, the conductive plates are shallow enough to be tested with RC drill holes.

Lunnon will review these plates coupled with the historical WMC drilling, to plan a follow-up program to confirm the modelled interpretations.

Any nickel mineralisation discovered on East Trough will, when coupled with the expedited programme at ECO-H/W, add to the potential for the East Cooee area to be a second centre of mineral resource growth at the Kambalda Nickel Project.
