Nimy Resources: Drilling returns copper-silver-zinc intersection followed by 487m nickel-copper ultramafic zone - Mons Nickel Project, WA
- Excellent result from first hole at the Dease prospect provides strong evidence that Mons hosts additional mineralised styles.
- The first diamond drill hole at the Dease prospect within the Mons project (NRDD004) has successfully intersected the first of three targeted MLEM conductive anomalies.
- The drill hole was designed to target a conductive anomaly modelled to be between 325-375m downhole. The anomaly was intersected where it was anticipated.
- Logging has recorded porphyritic felsic and mafic rocks from 216m to 291.2m passing into a intercalated schistose mafic and porphyritic felsic (porphyry) rocks zone to 383.6m, thereafter ultramafic rock was drilled to 870.8m end of hole.
- The conductive anomaly returned elevated copper, silver, zinc and sulphur values within visible sulphides when tested with a portable XRF.
- The 487.2m ultramafic interval confirmed to carry nickel and copper mineralisation when tested with portable XRF.
- Down-hole, electro-magnetic survey scheduled for mid-July.
Nimy Executive Director, Luke Hampson, commented:
“The successful intersection of the first conductor plate drilled at Dease opens up the potential for additional mineralisation styles at the Mons Project.
Result follows intersection of nickel and copper in the first holes at nearby Godley target and we have now intersected anomalous nickel and copper over significant widths at both Dease and Godley.
Drilling has been completed at the Dease Gossan and currently in the logging and sample preparation process and we look forward to these results adding further information to the Dease prospect profile”.
Summary
Nimy Resources (ASX:NIM) is pleased to announce the first diamond drill hole at the Dease prospect within the Mons project (NRRD004) has successfully intersected the first of three interpreted anomalous Moving Loop Electromagnetic (MLEM) conductors.
The drill hole was collared (MGA collar coordinates 661440E, 6678494N, dip 60⁰ and azimuth 305⁰) targeting the conductive anomaly estimated to be intersected between 325 – 375m downhole.
The hole has been logged from 216m and encountered porphyritic felsic and mafic rock from 216m to 273.1m passing into an intercalated schistose mafic and felsic porphyry zone to 383.6m whereby ultramafic rock (minor mafic and felsic) was drilled to 870.8m (end of hole).
The conductive anomaly sits within this schistose mafic-porphyry zone which returned elevated copper, silver, zinc and sulphur values associated with visible sulphides when tested with a portable pXRF.
Below the intersection of the conductive anomaly (Figure 2) the komatiitic ultramafic began at 383.6 continuing to the end of hole at 870.8 (487.2m).
The 487.2m ultramafic interval returned anomalous nickel and copper readings when tested using a portable XRF.
Coupled with the first diamond drilling (two holes) at Godley, the Dease hole confirms that both prospect areas contain extensive and thick ultramafic units hosting nickel and copper mineralisation. Downhole electro - magnetic survey’s will commence in mid - July at completed holes (Dease and Godley).
The primary objectives of obtaining lithological, structural, and mineralisation information have been met on the first two holes at Godley whilst the Dease hole remains open at depth.
The significance of the copper, silver, and zinc mineralisation within the conductive plate and its relationship, if any, with a copper-zinc-lead-gold in soil geochemical anomaly approximately 2.5 km south west of the conductive plate is being assessed.
Drill hole NRDD004 has intercepted the middle plate approximately 2.5 km northeast of the coincident soil anomalies. Reverse circulation drill hole NRRC006 drilled in October 2020 (178m EOH) above the plate anomaly, reported anomalous intervals of nickel, copper and gold.

Summary of significant intersections in NRRC006
Table 1 and Figure 3 below detail significant intersections in RC hole NRRC006 based on geochemical assays. A cut-off grade of 1500 ppm Ni (0.15%) has been applied to reflect the presence of anomalous mineralisation and in consideration of the stage of exploration. Details of the RC drilling and sampling techniques are provided in the Table 1 declaration. The location of the Dease target relative collars are given in Table 3.

Figure 3 - Reverse Circulation Hole NRRC006 assay values downhole
The interval in hole NRRC006 encountered ultramafic rock at 57m until the end of hole at 178m with four quartz vein intersections within the ultramafic (max intercept 2m) MgO levels averaged 24.23% from 57m - 178m (end of hole) with a peak MgO value of 31.67%. Anomalous copper (>300ppm) was restricted to clay and saprolite, however, a quartz vein in fresh rock intercepted 1270ppm (0.13%) from 114-115m. Gold was primarily located in the sap-rock with an anomalous 3m interval (70ppb including 1 metre at 142ppb) within 42-45m,, additionally a 37ppb Au quartz vein intercept was returned from 159-160m. Details of the NRRC006 intersections are provided in Table 1 and Figure 3.

COPPER MINERALISATION
The centre of tenement E77/2255 contains anomalous surface samples indicative of copper (984 ppm Cu) and gold (92 ppb Au). Mineralisation coincident with potassium zone alteration visible on radiometric imaging auger sampling over the area has defined anomalous Au, Cu, Zn and Pb (Figure 4). Regional and ground magnetics indicate two magnetic highs and a magnetic low proximal to the potassium alteration zone. Based on modelling of the surface geochemical signatures, an initial concept indicates a potential copper porphyry system. Further work is underway to define the relationship among the varying critical rock types.

Work Management Process
Core logging, photography, specific gravity, structural, magnetic suseptability and sample preparation have been completed in Kalgoorlie by an independent consultant prior to transport to Perth for geochemical analysis.
Nimy collated pXRF readings of Ni, Cu, Ag, S, MgO and SiO2 levels to assist in lithological logging and initial identification of mineralisation styles present.
An Olympus Vanta Series pXRF was used to collect the readings.
Work plan status
The Company’s immediate work plan includes the following:
- Hole NRDD006 (Gossan area – Dease prospect, Figure 12) drilling completed – pXRF to be completed - core to be packed and despatched to Kalgoorlie
- Hole NRDD003 (conductor plate – PHDD001) drilling commenced
- Awaiting assay results on first two diamond holes - NRDD001, NRDD002
- Additional geochemical and petrography test-work is to be completed on selected sections of the core to determine the mineralogy and mineralisation types in each of the discrete anomalous zones with higher nickel and copper grades.
- Drill holes are to be reviewed to determine the stratigraphic orientation of the ultramafic komatiite flow or flows, lithological connections of the mineralised zones and the structural orientation of the basal contact.
- Downhole EM (DEM) will be completed on Dease / Godley prospect area (commencing mid-July)
- Current and historic information will be combined and used to plan additional exploration at both the Dease and Godley prospects.
- Nimy continues to update Mons exploration potential thus providing a pipeline of exploration targets

About Nimy Resources and the Mons Nickel Project
Nimy Resources is an emerging exploration company, with the vision to responsibly discover and develop an economic nickel-sulphide project in a Tier 1 jurisdiction, Western Australia.
Nimy Resources has prioritised the development of the Mons Project, a district scale land holding consisting of 12 tenements, an area over 1,761sqkm along an 80km north/south strike.
Mons is located 140km north of Southern Cross and covers the Karroun Hill Nickel district on the northern end of the world-famous Forrestania nickel belt. Mons features a very similar geological setting to the southern end of the Forrestania belt and the Kambalda nickel belts.
The project is situated within a large scale fertile “Kambalda-Style” and “Mt Keith-Style” Komatiite sequences within the Archean Murchison Domain of the Youanmi Terrane of the Yilgarn Craton.
