DRILLING TO COMMENCE AT HIGH-GRADE NEPEAN NICKEL PROJECT
Highlights
-
3,500m reverse-circulation ( RC ) drill programme to commence next week at the high-grade Nepean Nickel Project in Western Australia
-
The project contains the historic high-grade Nepean nickel sulphide mine, which produced 32,303t of nickel metal at an average recovered grade of 2.99%Ni[1]
-
The programme will test possible near-mine extensions to the high-grade nickel sulphide mineralisation, as well as previously untested high-priority targets along the 10km of underexplored strike
-
The drilling is expected to take several weeks, with results reported to the market as they are received
-
Auroch remains in a strong cash position to continue aggressive exploration at its three highgrade nickel sulphide projects in WA to leverage the strong nickel price as it climbs well above US$17,000/t
Auroch Minerals Limited ( ASX:AOU ) ( Auroch or the Company ) is pleased to announce drilling will commence next week at its high-grade Nepean Nickel Project ( Nepean ), located 25km south of Coolgardie, in Western Australia (Figure 1).
The RC drill programme will test possible near-mine extensions to the high-grade nickel sulphide mineralisation, as well as previously untested high-priority targets along the 10km of underexplored strike of the Nepean mafic-ultramafic mine stratigraphy and/or aeromagnetic anomalies (Figure 2).
The Nepean Nickel Project contains the historic high-grade Nepean nickel sulphide mine, which was the second producing nickel mine in Australia, producing 1,108,457t of ore between 1970 and 1987 for 32,202t of nickel metal at an average recovered grade of 2.99% Ni[1] .
The Company has identified several near-mine drill targets to potentially extend the known high-grade massive nickel sulphide mineralisation, particularly along strike to the south where historic RC drilling successfully intersected very high-grade nickel sulphide mineralisation, including[1] :
-
3m @ 11.78% Ni from 37m (NP084470-2)
-
3m @ 9.93% Ni from 49m (NP084480-1)
-
4m @ 6.63% Ni from 46m (NP084470-1)
-
6m @ 2.82% Ni from 53m (NP084490-1).
In addition to the near-mine prospectivity, the drilling will test several high-priority targets along strike within the 3,128ha tenement package, where aeromagnetic anomalies align with the Nepean maficultramafic mine stratigraphy to create compelling drill targets with high potential for nickel sulphide mineralisation.

Auroch Managing Director Aidan Platel commented :
“ We are very excited to be kicking off our 2021 exploration programmes with a RC drill programme at the recently-acquired high-grade Nepean Nickel Project. In addition to exploring the extents of the known high-grade nickel sulphide mineralisation in and around the historic mine, we look forward to drilling high-priority targets further along strike which we believe have enormous potential to host further significant nickel sulphide mineralisation.
With the nickel price already well over US$17,000/t and forecast to continue to rise significantly over the next few years, 2021 will be a transformational year for Auroch as we consolidate our existing highgrade nickel sulphide resources and move towards scoping studies, whilst at the same time continue to aggressively explore for new nickel discoveries.”
The RC drill programme will comprise approximately 30 holes for 3,500m and is expected to take several weeks. Down-hole electromagnetic ( DHEM ) surveys will then be undertaken to assist in modelling and definition of any potential further mineralisation. The results from the drilling and DHEM surveys will be released to the market as they are received.

| CRITERIA | EXPLANATION | COMMENTARY |
|---|---|---|
| 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. |

| Relationship between mineralisation widths and intercept lengths |
● These relationships are particularly important in the reporting of Exploration Results. ● If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. ● If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length,true width not known’). |

● All results related to mineralisation at Nepean have been reported in the Significant Intercepts Table. |
| Other substantive exploration data |
● Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
