-
Exploration programmes progressing as planned and have not been impeded by recent Covid19 restrictions
Auroch Minerals Limited ( ASX:AOU ) ( Auroch or the Company ) is pleased to provide an update on the exploration activities at its high-grade Nepean Nickel Project ( Nepean ), located 25km south of Coolgardie, in Western Australia. The project is operated under the Company’s 80:20 JV agreement with Goldfellas Pty Ltd ( Goldfellas ).
The Company’s 3,500m RC drill programme is progressing on schedule and is approximately one third of the way through, with 12 drill-holes completed for 1,012m (see Table 1). The programme was designed to test the extents of shallow near-mine mineralisation, as well as several aeromagnetic targets along the 10km of prospective strike at Nepean which have very high potential to host further significant nickel sulphide mineralisation.
The initial 10 drill-holes completed (742m) targeted shallow high-grade nickel sulphide mineralisation near the historic Nepean nickel mine. The holes were drilled to test if the shallow high-grade nickel sulphide mineralisation identified approximately 200m to the south of the mine by Focus Minerals Ltd (ASX:FML) in 2007-08 extended all the way back to the remnant nickel sulphide mineralisation in the mine itself (see Figure 1 and Figure 2).
The RC chip samples from these 10 drill-holes have been logged and submitted to the ALS Global laboratory in Perth for analyses, with assay results expected with the next 1 – 2 weeks.
The drill-rig has now moved to test exciting regional aeromagnetic targets along the 10km of prospective strike to the north and south of the historic Nepean nickel mine (see Figure 3). These drillholes have been designed to characterise the ultramafic units along strike and to define the important stratigraphic contact between the ultramafic hanging-wall and the basalt footwall.
All exploration drill-holes will be cased for follow-up down-hole electromagnetic ( DHEM ) surveys to test for any nearby conductive units that may represent massive nickel sulphide mineralisation. The remaining programme is expected to be completed in the next 2 – 3 weeks.
Auroch Managing Director Aidan Platel commented :
“We are pleased with the progress of our maiden RC drill programme at the Nepean Nickel Project, and are eager to see the assay results of the initial shallow holes that have the potential to join the known shallow high-grade nickel mineralisation 200m to the south of the Nepean mine back to the remnant mineralisation in the mine itself.
ASX ANNOUNCEMENT 4 February 2021
==> picture [163 x 43] intentionally omitted <==
We are also very excited to now be drilling the aeromagnetic targets along the 10km of prospective strike at Nepean, all of which have very high potential to host significant nickel sulphide mineralisation, yet they have never been previously explored with modern techniques.
We are expecting first assay results within the next fortnight and we look forward to the next market update when they are received.”
In addition to the current RC drilling, the Company has designed a 3,000m AC drill programme to define the ultramafic stratigraphy and footwall contact(s) over the 10km of strike at Nepean. The drilling will be used to define the stratigraphic sequence, provide basement geochemistry and test for any potential channel embayments, and will commence in mid-February. The results from this programme will be used by the Company to produce a detailed litho-geochemical model over the full strike length of the Nepean project area, to be utilised for targeting for the next phases of drilling.
Also planned for this quarter at the Nepean Nickel Project is a modern high-powered ground MLEM survey over two critical areas to the north and south of the historic Nepean nickel mine. Modern EM surveys utilise significantly more current than historic surveys and have been proven as a technique for locating conductive geological units such as massive nickel sulphide bodies. The planned survey at Nepean was designed over prospective areas of the Nepean strike in order to vector in on possible massive nickel sulphide mineralisation and hence provide further high-potential targets for subsequent drilling campaigns.
The Company is pleased to advise that, despite recent covid-19 lockdowns and restrictions in the Perth and south-west WA regions, its exploration programmes and scheduling have not been affected. Recent heavy rainfall in the Goldfields region due to cyclone-related fronts have caused minor downtime to the drill programmes due to reduced access, but this is not expected to impact on the overall schedule.

| Sampling techniques |
● Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. ● Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. ● Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1m samples from which 3kg was pulverised to produce a 30g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
