Narryer survey maps out more potential nickel, copper, PGE anomalies

Narryer is preparing to carry out field reconnaissance over multiple conductivity anomalies identified by a recent airborne electromagnetic survey over the Mt Nairn area.
While the data requires final processing and modelling, initial results show several key conductors have affinity to massive potential nickel, copper and platinum group element sulphides below surface.
Of particular note is a conductor in the Irrida area that is about 300m along strike from historical drilling which intersected ultramafic rocks containing disseminated sulphides and anomalous nickel, copper and gold.
Narryer Metals (ASX:NYM) will now carry out field reconnaissance to ground-truth anomalies and rank targets for follow up with either geochemical surveys or drill testing.
EM survey results
The company had carried out the 1,660 line kilometre EM and magnetic survey at a 200m line spacing with additional infill lines at the 100m spacing undertaken over anomalous areas at the Mt Nairn tenements within its namesake Narryer project in WA’s Gascoyne region.
This survey identified 19 EM anomalies within the Milly Milly, Irrida and Cn2 areas of the Mt Nairn survey area, 10 of which are considered to be high priority.
Milly Milly is a 25km north-northeast to south-southwest trending zone containing discrete pods of outcropping / sub-cropping mafic-ultramafic intrusive rocks and banded iron formations.
Previous soil and rock chip samples returned results up to 0.7% nickel.
Of the 13 anomalies identified on this trend, five have a strong bedrock signature resembling massive sulphide in bedrock, with 200 to 700m in strike length.
Irrida is a sub-cropping peridotite and ultramafic caprock with coincidental magnetic high bands that is along strike to Desert Metals’ (ASX:DM1) Irrida Hill and Innouendy prospects.
Several bedrock conductors have been identified that are coincidental to magnetic highs and sub-cropping ultramafic rocks.
Meanwhile, Cn2 was first defined by Desert Mines and Metals Limited in 2012 as an area with poorly outcropping ultramafic rocks with anomalous chromium and nickel from weathered rock chip samples, coincidental magnetic highs, and widespread magnesite at surface.
Narryer’s survey identified a strong conductor which is consistent over several survey lines about 200m along strike of the only interpreted bedrock conductor identified from the 2012 VTEM survey that was not drilled and remains a target.
The area appears to be undercover and to coincide with the edge of a magnetic high.
