-
Two holes completed – First of two conductors tested at Innouendy confirmed as magmatic sulphides in mafic intrusive rocks.
-
IRRD006 intersected ~22m of disseminated to networked pyrrhotite with minor disseminated chalcopyrite.
-
IRRD007 intersected a ~5m zone (198-203m) of disseminated, networked and narrow zones of massive pyrrhotite with traces of chalcopyrite. Network textured chalcopyrite and pentlandite were also identified at 228.5m over 15cm (visual logging + handheld XRF analysis).
-
Sulphide intersections are validation for the intrusive Ni-Cu-PGE exploration model in this terrane. Desert Metals believes these to be the first ever intersections of magmatic massive sulphides anywhere in the Narryer camp.

Desert Metals Limited (“Desert” or the “Company”) is pleased to announce encouraging results from the first two holes of its 13 hole drilling program. Magmatic sulphides have been intersected in mafic intrusive rock in the first of 2 targets at Innouendy.
In its initial drilling campaign, the Company has targeted six conductive plates at two prospects 20 km apart (two at Innouendy and four at Irrida Hill, see ASX release 12[th] April 2021). The Company had previously suggested that these conductors could be caused by massive sulphides associated with intrusive Ni-Cu-PGE deposits. Visual results from drill core confirm that the eastern plate at Innouendy is caused by disseminated to massive sulphides and not magnetite as hypothesised by previous explorers. It is believed to be the first significant intersection of intrusive magmatic massive sulphide anywhere in the Narryer, confirms the applicability of the exploration model, and upgrades the prospectivity of Desert’s entire license package over the North-western Craton margin (> 1600 sqkm).
Hole 1 (IRRD006) intersected an approximately 22m wide zone (162-184m) of disseminated to occasionally networked pyrrhotite with minor pyrite and traces of chalcopyrite hosted in a medium-coarse grained mafic intrusive (modelling predicted intersection to be at 190m).

Hole 2 (IRRD007) intersected had an approximately ~5m wide zone (198-203m) of disseminated, to networked and semi-massive pyrrhotite ( +/- pyrite, trace chalcopyrite), with one semi-massive zone at 202-202.4m (compared to the modelled EM conductor intersection at 213m). A smaller sulphide zone at 228.5m contains 10-20cm of network textured sulphides with chalcopyrite, pyrrhotite and pentlandite. Both sulphide zones are hosted in a mafic intrusive rock.
The two holes were designed to intersect the eastern of two conductive plates at Innouendy and one of six plates overall being targeted by the initial drilling campaign at Innouendy and Irrida Hill. This conductor had been targeted unsuccessfully by previous explorers with six historic drillholes. Down hole EM is being planned and the Company is awaiting assay results for Copper, Nickel, Cobalt and Platinum group elements from these drill holes before deciding what further work is needed to define any mineralisation in the eastern plate.
Drillhole INDD008 is currently at approximately 150m and designed to test the western Innouendy plate (Figure 2). This plate is modelled to be deeper, larger and more conductive than the eastern one. The drill hole is interpreted to intersect the plate at approximately 260-280m.
After testing both plates at Innouendy the drill rig will move 20km south to test the four conductive plates at Irrida Hill where RC pre-collars have been drilled.
A ground EM crew will be arriving on site in the second week of May to follow up on 6-12 anomalies identified from the Airborne survey flown in February. The helicopter EM crew will return in late May to fly the Company’s eastern licenses from which further conductors may be prioritised for ground follow up and drilling.
Managing Director Dr Rob Stuart commented “These visual results from our first ever drill holes are extremely encouraging. Several years ago the Company staked ground on the hypothesis that the Narryer Terrane was prospective for intrusive Ni-Cu-PGE deposits. The intersection of magmatic massive sulphides in intrusive rocks validates the exploration model and the Company’s methodology. While we are, of course, awaiting assays, these results have us excited about the potential for the rest of the winter work program, our drilling campaign and the Narryer Terrane in general.”
