AC RESULTS DEFINE NICKEL SULPHIDE DRILL TARGETS AT VALDEZ
Highlights
-
Assay results received and modelled for the recently completed air-core ( AC ) drill programme over the Valdez Prospect
-
Results show thick intercepts of elevated nickel within a prospective and highly-fertile channel
-
Modelled channel is coincident with both an aeromagnetic high and an electromagnetic (EM) anomaly, further increasing the potential to host massive nickel sulphides
-
Follow-up reverse-circulation (RC) drill programme to test the new channel target at depth is scheduled to commence within two weeks
-
Diamond drilling is ongoing at the Saints Nickel Project with results pending
Auroch Minerals Limited ( ASX:AOU ) ( Auroch or the Company ) is pleased to announce it has received and modelled all assays from the first-pass AC drill programme completed in July at the exciting Valdez Prospect within the Company’s 100%-owned Leinster Nickel Project ( Leinster ) in Western Australia.
A full litho-geochemical review and model of the results has successfully defined a highly-fertile ultramafic ( UM ) rock unit within an embayment or channel with a strike length of over 150m. Thick zones of anomalously high nickel values were intersected within this prospective channel, including[1] :
-
9m @ 0.41% Ni from 33m, including 3m @ 0.52% Ni from 39m (VZAC013)
-
6m @ 0.37% Ni from 48m (VZAC008)
-
6m @ 0.35% Ni from 66m (VZAC009).
The significant intersections of nickel are hosted within a high MgO ultramafic unit in a modelled basal channel which lies above aeromagnetic anomalies, and are also coincident with a strong EM conductor defined by a historic surface moving-loop electromagnetic ( MLEM ) survey (see Figure 1). All of these characteristics are favourable for massive nickel sulphide mineralisation and hence further enhance the potential of the Valdez target.
A follow-up RC drilling campaign to test these new targets and acquire down-hole EM ( DHEM ) data to help vector in on potential nickel sulphide mineralisation has already been planned and permitted, and will commence within the next two weeks.
Auroch Managing Director Aidan Platel commented :
“ Since its acquisition, the Valdez Prospect has been considered a high-potential exploration target, given its location and proximity to Saracen’s (ASX:SAR) high-grade Waterloo Nickel Mine. The Company’s exploration strategy is once again proving effective in advancing early stage targets to high-priority drill targets. The excellent nickel results from the recent AC drilling of the weathered profile really highlights the potential of significant massive nickel sulphide mineralisation underneath
1 Significant intersections calculated at ≥ 0.3%Ni, samples were 3m composites; see Table 1 for full list of results

Photo 1 – Air-core drilling at the Valdez Prospect of the Leinster Nickel Project
The aim of the ~4,400m AC programme completed in mid-July was to characterise the ultramafic package at Valdez, in particular where it overlies the strong MLEM anomaly. The ultramafic unit at the Valdez Prospect is the same unit which hosts Saracen Mineral Holding Ltd’s ( ASX:SAR ) Waterloo Nickel Mine along strike. Historic drilling (predominately RAB), partially defined a north-south -striking ultramafic unit overlying the MLEM anomaly; however, the historic data was too shallow and widely spaced and hence insufficient for detailed characterisation or identification of any possible fertile channels. Given the deep nature of the MLEM anomaly, Auroch implemented the same systematic exploration strategy which has provided recent success at its Saints Nickel Project, and completed 11 AC lines across the ultramafic unit comprising 61 drill-holes for 4,411m.
Litho-geochemical review of the results and modelling of the basal ultramafic-mafic contact has defined a prospective channel overlying both a magnetic high and the MLEM anomaly (Figure 1). The ultramafic unit within the modelled channel is characterised as highly fertile based on geochemical signatures including elevated Ni (>0.3% Ni), high MgO, elevated Cu and Ag, and low Cr and Zn, all of which are considered favourable characteristics for hosting significant Kambalda-style massive nickel sulphide mineralisation.
The next exploration phase at Valdez will consist of 3-5 RC drill-holes over the 150m strike length of the channel. The holes will aim to intersect the basal ultramafic-mafic contact at a (down-hole) depth of 150-200m, well into the fresh rock, and will extend a further 50m into the mafic unit. All holes will be surveyed with DHEM to identify any potential conductive bodies (e.g. massive sulphides) within the channel area. The drilling campaign has been permitted and is scheduled to commence within the next two weeks.
The diamond drilling programme at the Saints Nickel Project is ongoing, with initial results expected to be received by the end of next week.

JORC Code, 2012 Edition, Table 1 (Valdez Prospect) Section 1: Sampling Techniques and Data
| CRITERIA | JORC CODE 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. |
● Geochemical samples at Valdez have been produced by drilling from surface to 464m, vertical depth. Drilling methods employed from 1996-2015 include aircore, rotary air blast (RAB)s, percussion/ reverse circulation (RC) and diamond cored drilling. ● Aircore, percussion and RC drilling returns a sample of broken rock collected in a bag at site at the time of drilling. Drill core from diamond drilling technique is later split by a core saw. ● Documentation of measures taken by previous operators (Breakaway Resources and WMC/Forrestania Gold) 1993-2010 to ensure sample representivity is not available. ● Historical drill core has been geologically logged by experienced geologists with core orientation determined where possible, allowing accurate 3- dimensional location of the Saints mineralisation. RC drill chips were geologically logged every 1m by experienced geologists. ● Historic drill hole assays, in conjunction with historic geological logging data, have been used by AOU to gain an understanding of the mineralisation at Horn. ● 1996-2005 (WMC/Forrestania Gold): RC samples, 1 - 4m composites and 0.19 – 1.9m composite diamond core samples, Analysis at Genalysis Laboratories Multi Acid Digest - Inductively Coupled Plasma Optical (Atomic) Emission Spectrometry ● 2006-2011 (Breakaway): 4m RAB composite samples, Genalysis ATOES ● 2020 (Auroch Minerals): Air Core drilling produced a 1m bulk sample collected in green plastic bag from an onboard cyclone. 3m composite samples were collected via scoop, 1m end of hole samples were collected via scoop. All samples were submitted to ALS Minerals, ME-MS61, PGM- ICP23 conducted on all samples. |
| Drilling techniques | ● Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). |
● 1996-2005 (WMC/Forrestania Gold): AC/RAB, 10 RC-percussion holes for 1699m diameter unspecified, no downhole surveys; 11 diamond core drill holes for 4097m - diameter unspecified, 30m downhole surveys by Eastman Single Shot camera. ● 2006-2010(Breakaway): 28 RC holes for |

| Drill sample recovery |
● Method of recording and assessing core and chip sample recoveries and results assessed. ● Measures taken to maximise sample recovery and ensure representative nature of the samples. ● Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
● Sample recovery assessment details not documented by previous operators WMC/Forrestania Gold. ● Sample recovery assessment details not documented by previous operators Breakaway Resources. ● 2020 AC drilling; sample recovery, moisture content are recorded for each metre in field at the time of drilling. |
| Logging | ● Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. ● Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. ● The total length and percentage of the relevant intersections logged. |

| Data spacing and distribution |
● Data spacing for reporting of Exploration Results. ● Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. ● Whether sample compositing has been applied. |
● 1996-2005 (Forrestania Gold): Typically sampled in 1-4 metre intervals, skipping intervals of no interest and increasing the frequency of sampling depending on the geology observed in diamond drill core (smallest sample length 0.1m). ● 2006-2010 (Breakaway Resources): Drilling typically sampled in 4 metre intervals from start of hole, increasing the sampling rate to every metre or to more detail depending on the geology observed in diamond drill core (smallest sample length 0.15m). ● Drill data spacing of historic drill data (1996-2010) is sufficient to establish the degree of geological and grade continuity appropriate for estimating an Inferred Ni Resource. ● 2020 Auroch Minerals; Air Core drilling was conducted on 40mx80m and 80mx160m grids, this close spaced drilling provides accurate control on geology in poorly tested areas. |
| Orientation of data in relation to geological structure |
● Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. ● If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
● Historical drill holes were oriented, as far as reasonably practical, to intersect the centre of the targeted mineralised zone perpendicular to the interpreted strike orientation of the mineralised zone. ● The geometry of drill holes relative to the mineralised zones achieves unbiased sampling of this deposit type. ● No orientation-based sampling bias has been identified. |
| Sample security | ● The measures taken to ensure sample security. |
● It is assumed that due care was taken historically with security of samples during field collection, transport and laboratory analysis. ● 1996 – 2005 (Forrestania Gold): No location of drill samples or core is documented in historical annual reports. ● 2020(Auroch Minerals); Chipsamples |

| aggregation methods |
grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. ● Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. ● The assumptions used for any reporting of metal equivalent values should be clearlystated. |
by it’s corresponding interval length, as is industry standard practice. ● Grades >0.3% Ni are considered significant for exploration purposes. ● A lower cut-off grade of 0.3% Ni has been used to report the Exploration results. Top- cuts were deemed not applicable considering the style of Ni mineralisation. ● Metal equivalent values have not been used. |
| 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’). |
● Most drill holes were angled to the East so that intersections are orthogonal to the orientation of mineralisation. |
| Diagrams | ● Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
● Relevant diagrams have been included within the announcement. |
| Balanced reporting |
● Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
● All results 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 contaminatingsubstances. |
● No other substantive data exists. |
| Further work | ● The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). ● Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commerciallysensitive. |
● Refer to diagrams in the body of text. |
