Nimy Resources (ASX:NIM) reports 2 diamond holes (NRDD001, NRDD002) collared on the same pad as part of the first deep drilling at the Mons Project has confirmed a ‘significant’ body of nickel mineralisation at the Godley prospect.
The 2 holes at the prospect, located 140km north-northwest of Southern Cross in Western Australia, have provided ‘excellent’ information enabling the primary objectives of obtaining lithological, structural, depth (basal contact) and mineralisation information to be met.
NRDD001 returned a ‘substantial’ intersection of 368m @ 0.14% Ni and 25.72% MgO from within 12m to 395m which includes pre-collar (NRRC002).
NRDD002 returned a ‘substantial’ intersection of 427m @ 0.14% Ni and 26.03% MgO from within 19m to 456m.
A cut-off grade of 1,000ppm nickel allowing for less than 2m internal dilution has been applied.
The extent of the strike (drillholes containing 1m > 1,000ppm nickel) is approximately 39.4km with a width of approximately 6.2km (inferred at 80km strike by 11km width).
The point-to-point polygonal area containing potential nickel mineralisation measures approximately 182.5km-square.
Both holes intersected intervals of nickel sulphide (pentlandite), copper sulphide (chalcopyrite) along with pyrite and pyrrhotite.
MgO is significant in helping determine the rock type (Ultramafic less than 18% MgO).
Mineralisation remains open with Ni-Cr and (Ni-Cr)-(Cu-Zn) ratios being applied supporting a western contact accumulation of the possible ore-grade mineralisation.
The ratios support the structural interpretation around D1 of the komatiite flow, now dipping to the east-southeast with the basal contact expected on the western contact of the flow.
The Dease prospect has further results pending including diamond hole NRDD004 whereby a 487.3m intersection of komatiite ultramafic rocks was logged beginning at 383.6, and continuing to the end of hole at 870.8m, demonstrating evidence for a ‘large’ mineralising system at the Mons Project.
Also at Dease, the gossan discovery and pending geochemical results currently being assayed take on special significance.
Downhole EM was completed in NRDD002 and did not detect a bedrock conductor within an estimated range of 50m from the hole.
The result is consistent with the hole location within the structural model relative to the basement.
Electromagnetic massive sulphide bedrock conductors are detectable within a limited range of a downhole survey and disseminated sulphides are generally not detectable.
A MLEM survey was completed over the Godley Prospect, and the survey was impacted by large areas of induced polarisation (IP) effects causing the EM response to be reduced or even negative.
It has been recommended to Nimy that a Fixed Loop Electromagnetic (FLEM) survey coupled with a SQUID sensor be undertaken.
Work has commenced assessing the current data set including manually removing the IP effect and the merits of the FLEM SQUID survey. The MLEM data is being modelled in conjunction with radiometrics, gravity, DEM data, drilling, geological mapping and modelling, and geophysical datasets.
The EM data is currently undergoing decay channel gridding, imaging and conductor plate modelling.
The resultant work will assist in further target generation and drillhole planning at the Godley prospect.
This updated information will continue to be used for updating the Mons exploration targeting model and pipeline of exploration targets.
Nimy Resources Executive Director Luke Hampson said the results of the first diamond holes at the Godley prospect have provided a wealth of information taking the Mons Project forward.
“The Ni, Cu, S, MgO associations carried within the komatiite indicate a fertile setting for nickel sulphides.
“The Nimy exploration strategy is targeted at significant high-grade massive nickel sulphides and large low-grade nickel deposits”
The Nimy exploration strategy is targeted at significant high-grade massive nickel sulphides and large low-grade nickel deposits.
Dip and orientation are similar to the Forrestania model, and this will inform along with MLEM interpretation the upcoming drilling campaign as we take higher grade nickel sulphide accumulation.
The substantial intervals of nickel mineralisation also furthers the possibility of a large low-grade deposit similar to those progressing around the world cognisant of forecast supply shortages. The deepest holes yet drilled at the Mons Project have delivered an effective test for mineralisation, structure, lithology and basal contact.
“The upcoming results from the Dease prospect are awaited in further vectoring towards the higher grades of nickel. Concurrently the lithium anomalies will be examined.”
The company notes that anomalous levels of lithium has been returned with narrow intervals of NRDD001 and NRDD002.
The lithium mineralisation in NRDD001 is confined to areas of pervasive to extreme biotite alteration and is clearly shown in breaks to the MgO%. The lithium mineralisation in NRDD002 is somewhat different, showing up in smaller intervals within predominantly ultramafic.
The presence of lithium in small quantities is noted and suspected to be carried within biotite and further research is underway.
Nimy’s forward work plan at the Godley prospect includes:
- Complete MLEM survey analysis, decay channel gridding, imaging and conductor plate modelling.
- Complete model in conjunction with radiometrics, gravity, DEM data, drilling, geological mapping and modelling and geophysical datasets.
- Target generation and drillhole planning at the Godley prospect.
The Dease prospect has 4 diamond holes awaiting geochemical assay completion.
Dease prospect MLEM survey analysis is underway and will be coupled with structural interpretation, lithology and interpretation of geochemical results upon receipt.
The completed MLEM survey data over the Godley Prospect is in the process of decay channel gridding, imaging, conductor plate modelling and target generation feeding into drillhole planning.
The MLEM data will be modelled in conjunction with magnetics, radiometrics, gravity and DEM data to produce detailed structural imagery.
The completion of this will be a first look at the Mons Project Godley Prospect in such detail and will help dictate exploration strategies employed across the entire Mons Project area.
Nimy Resources is an emerging exploration company, with the vision to responsibly discover and develop an economic nickel sulphide project in Western Australia.
The company has prioritised the development of the Mons Project, a district scale land holding consisting of 15 approved tenements over an area of 2,564km-square covering an 80km north-south strike of ultramafic.
Mons is located 140km north-northwest of Southern Cross, Western Australia, and covers the Karroun Hill nickel district on the northern end of the ‘world famous’ Forrestania nickel belt.
Mons features a similar geological setting to the southern end of the Forrestania nickel belt and the Kambalda nickel belt.
Mons is situated within potentially large-scale fertile ‘Kambalda Style’ and ‘Mt Keith Style’ nickel rich komatiite sequences within the Murchison Domain of the Youanmi Terrane of the Archean Yilgarn Craton.
