Significant Shallow Nickel Results from Aircore Drilling at the Innouendy Project
Highlights
• Reconnaissance aircore drilling at the Innouendy Project has returned a number of significant nickel intercepts close to surface which could indicate a potential deeper sulphide source
• Newly identified Cattle Yard Nickel prospect returns:
• 32m @ 0.65% Ni from 16m to EOH, including:
• 4m @ 1.76% Ni and 0.11% Co (believed to be highest grade nickel intercept recorded in the Narryer Terrane to date)
• 46m @ 0.25% Ni from 16m to EOH, including:
• 20m @ 0.35% Ni and 0.07% Co
• Mineralisation at the Cattle Yard Prospect extends over 100m along section and remains open along strike, to the southeast and at depth.
• Separate untested conductor returns:
• 4m @ 0.585% Ni from surface to EOH (Unweathered, possible sulphide source which is adjacent to large untested magnetic anomaly)
• A large follow up drilling program is planned to define the extent of the shallow mineralisation and target any associated sulphides
• Additional Innouendy aircore traverse also returns 500m of highly anomalous PGEs.
• Rare earth (REE) mineral Cerium (Ce) analysed above maximum limits (>500ppm) associated with elevated lanthanum (La) in multiple samples across 10 holes in lateritic clays
• Samples were not originally assayed for the full rare earth suite and are now pending re-assays results
• Drill Rig currently mobilising to Dingo Pass. Drilling of the high-conductance Dome anomalies due to begin this week.

New Nickel prospects at Innouendy
Desert Metals Ltd is pleased to report that reconnaissance aircore drilling has uncovered two highly prospective new nickel prospects at the Company's 100% owned Innouendy Project. (See Table 1, Figures 1,2)
The Cattle Yard Prospect was first targeted through airborne EM and a semi-coincident historical nickel intercept. 4m @ 1.76% in hole INAC036 is believed to be the highest-grade nickel yet intersected by anyone in the Narryer Terrane. The mineralisation is coincident with anomalous cobalt and chrome and occurs within a broader zone of 32m @ 0.65% Ni extending to the end of hole at 47m. Holes across a section > 100m width ended in mineralisation which is open along strike, at depth and to the southeast. Follow up drilling traverses will both define the extent of the shallow mineralisation and target a potential sulphide source.

A second prospect has also been identified approximately 3km to the northeast of the Cattle Yard (Figures 1,2). 4m @ 0.585% Ni was intersected from surface to EOH in fresh rock in hole INAC017. This traverse was targeting an inductive response in airborne EM data that appeared to be superimposed on a chargeable anomaly. Aircore drilling was unable to penetrate more than ~4-10m in this and neighbouring holes due to the very shallow cover. The high nickel grade in fresh rock suggests a sulphide source and the extent of the conductor and adjacent magnetic anomaly will now be tested with further drilling.

PGEs
The northern traverse of aircore drilling at Innouendy (holes INAC019 to INAC027) has defined a section >500m wide of highly anomalous PGE (Pt + Pd) within the regolith (Figure 3). Interestingly the southern line, closest to the original diamond hole which intersected anomalous PGEs, did not record significant intercepts. Further drilling is planned to better define the extent and source of this highly anomalous zone.
