ASX Announcement
31 May 2021
RC Drilling Identifies Wide Zone of Gold Mineralisation
OzAurum Resources Ltd ( ASX: OZM or OzAurum or the Company ) is pleased to announce further results from the Company’s initial 20,000 metre (m) Reverse Circulation (RC) drilling campaign, which have so far identified significant wide zones of gold mineralisation. The current RC results include 26 holes for 3,740m of drilling at the Mulgabbie North Project, situated North East of Kalgoorlie.
Highlights
-
Significant wide zones of gold mineralisation intersected, with mineralisation open along strike and at depth.
-
RC holes that intersected significant gold mineralisation, include:
-
20m @ 1.91 g/t gold (Au) – (within 46m @ 1.04 g/t Au from 73m) MNORC 040
-
9m @ 1.64 g/t Au – (within 52m @ 0.73 g/t Au from 102m) MNORC 041
-
4m @ 1.90 g/t Au – (within 35m @ 1.1 g/t Au from 124m) MNORC 042
-
6m @ 1.92 g/t Au – (from 35m) MNORC 045
-
6m @ 2.79 g/t Au – (from 200m) MNORC 051
-
4m @ 1.57 g/t Au – (from 153m) MNORC 055
-
7m @ 1.48 g/t Au including 1m @ 7.36 g/t Au – (from 36m) MNORC 051
-
Numerous RC holes intersected higher grade gold mineralisation within wide, lower grade zones such as MNORC 041 with 52m of mineralisation intersected downhole.
-
New gold zone identified west of the Ben Prospect, with primary gold mineralisation intersected at depth and associated with previously drilled aircore (AC) hole MNOAC 020 (see ASX Announcement 15[th] March 2021).

Mulgabbie North RC Drilling Results
The 26 holes that were drilled for 3,740m at the Mulgabbie North Project are a continuation of OzAurum’s initial 20,000m RC drilling campaign. A further 42 RC holes for 5,764m have also been drilled with assays still pending at the labs. To date, a total of 98 RC holes have been drilled at Mulgabbie North for 15,811m.
These excellent RC results, combined with recently announced aircore (AC) results defining new zones of mineralisation (see ASX announcement on 24 May 2021), further highlight the potential of Mulgabbie North to be a significant gold project.
Most notably, RC hole MNORC 040 intersected 20m @ 1.91 g/t Au from 25m within a wider zone of 46m @ 1.04 g/t Au. Numerous RC drill holes intersected higher grade gold mineralisation within wide lower grade intervals indicating Mulgabbie North is situated within a large mineralised gold system. Gold Mineralisation at Mulgabbie North is currently open at depth and along strike at both the Ben and James Prospects.
A new gold zone has been discovered south west of the Ben Prospect with MNORC 058 intersecting 19m @ 1.02 g/t from 112m depth. Our current interpretation is this deeper primary gold mineralisation is associated with previously intersected AC hole MNOAC 020 (see ASX release 15[th] March 2021).
A further 42 RC holes for 5,764m have been drilled testing Mulgabbie North’s previously discovered AC gold anomalies and the southern extension of the Ben Prospect. Some of these holes have intersected wide zones of quartz veining with associated pyrite and arsenopyrite mineralisation. At the Ben prospect a significant fault has also been intersected in 4 RC holes that has associated quartz veining and mineralisation. The Company is eagerly awaiting the results from these holes.
Wide zones of weak to moderate hematite alteration have been discovered in some RC holes at Mulgabbie North. Specifically, the hematite alteration indicates oxidised fluids from an intrusive complex suggesting proximity to the mineralising centre - likely to be within OzAurum’s 100% owned Mulgabbie North tenure.
The additional planned RC drilling at Mulgabbie North will further test strike and depth extensions of gold mineralisation at the James and Ben Prospects that are situated on the Relief Shear, as well as, western air core gold anomalies and associated mineralisation. Gold mineralisation at these prospects is hosted in the intermediate–felsic volcaniclastic units. The RC drilling program at Mulgabbie North will further scope out the extent of known mineralisation aimed at making a significant gold discovery.
Utilising best practice RC drilling, sampling and assay protocols will allow for a potential future JORC 2012 compliant resource to be estimated with confidence at Mulgabbie North. Systematic RC drilling is being undertaken on a 20m x 20m spacing and a limited number of historic + 33-year-old RC drill hole positions will be redrilled to meet JORC 2012 requirements.
Due to the current high demand on assay laboratories, the Company is experiencing long delays with receiving assay results, with up to an 8-week turnaround time.
Patricia RC Drilling to Commence
A maiden RC drilling program is planned at the Company’s advanced Patricia Gold Project, situated 40 km north east of Mulgabbie. The planned drilling program, which is expected to commence in the coming weeks, will target high-grade gold mineralisation. Historical high-grade gold intersections include PT 001 5m @ 18.8 g/t Au from 35m, including 1m @ 80 g/t Au. The 25m deep open pit at Patricia is 800m long and 150m wide.

Martin Holland to take on Head of Corporate Role
OzAurum Non-Executive Director and major shareholder, Martin C Holland, will be moving over to an Executive Director role as the Head of Corporate allowing the Managing Director and CEO, Andrew Pumphrey, to focus on the geological and technical aspects of exploration at the Mulgabbie and Patricia Gold Projects in Western Australia. A summary of the Consultancy Agreement setting out the terms of Mr Holland's engagement is as follows:
-
Commencement date: 1 June 2021
-
Term: No fixed term
-
Notice and termination: OzAurum may terminate the Consultancy Agreement at any time, by providing notice and paying the equivalent of three months of fees to Mr Holland. Mr Holland may terminate the agreement by providing three months’ prior written notice to OzAurum.
-
Monthly fee:
-
Other:
-
Mr Holland is entitled to receive a consultancy fee of $11,666.67 (excluding GST) per month.
The Consultancy Agreement otherwise contains standard terms and conditions for an agreement of this nature, including in relation to termination, confidentiality and retention of intellectual property.
OzAurum’s Chief Executive Officer, Andrew Pumphrey, said:
“The Company is very encouraged by the additional high-grade gold intercepts acheived through our RC drilling campaign thus far. These results, and the many results still pending in the assay labs, provide further confidence that ongoing RC drilling has the potential to unlock a significant gold project at Mulgabbie. In particular we are excited by the potential of this area where the host rocks are intermediate-felsic volcaniclastic units. In addition, the wide zones of Hematite alteration intersected in some deeper holes is very promising since this is a key signature of oxidised gold fluids, similar to that of Northern Star (ASX: NST) Carosue Dam Karari and Whirling Dervish Gold Mines. This area is under transported cover that has prevented previous effective exploration. ”
“Lastly, Martin’s executive appointment, as Head of Corporate, materially enhances OzAurum’s corporate marketing strategy, and allows me to be on the ground focusing on the Company’s strategic exploration program. We believe this aligned partnership enables the Company to fast track its objective of making a significant gold discovery,” Mr Pumphrey concluded.
In the coming months as drilling results become available the company will be providing the market with regular updates.

JORC Code, 2012 Edition – Table 1 Report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| CRITERIA | JORC CODE EXPLANATION | COMMENTARY |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. 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. |
The Mulgabbie North Deposit – Ben Prospect 26 RC holes (MNORC 039 - 064 3,740m), azimuth 225° dipping -60°. The RC samples are collected from the drill rig cyclone in a green plastic bag in 1m intervals and are laid out in rows of either 20, 30 or 40 samples. A 2-4kg representative sample is split via the rig mounted cone splitter and placed on top of the green plastic for that metre interval. Diamond drilling completed using one metre sampling lengths, core half cut adjacent to bottom of hole orientation line. Aircore samples are laid out in rows of 10. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
All sampling is undertaken using OzAurum Resources sampling procedures and QAQC in line with industry best practise which includes certified standards on average every 30 samples. The RC drill rig provides a sample at the end of each metre of drilling. A 2-4 kg sample is collected from the drill rig via a cone splitter which is representative of that metre. PQ diamond core was half cut to produce a 2-4 kg sample for analysis. Aircore composite samples weighing between 2-4 kg are collected from four one metre samples via a sample scoop with even quantities of each 1m sample collected to form the composite sample. |

| Aspects of the determination of mineralisation that are Material to the Public Report. |
Historic hole collars have been recovered where possible and surveyed by a licenced surveyor using a DGPS (0.01 m). |
|
| In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g 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 (e.g. submarine nodules) may warrant disclosure of detailed information. |
The RC one metre sample intervals were collected with a 2-4 kg representative sample despatched to the laboratory for gold analysis. The diamond half core sample intervals were typically a 2-4 kg representative sample despatched to the laboratory for gold analysis. The AC composite and one metre sample intervals were collected with a 2-4 kg representative sample despatched to the laboratory for gold analysis. All analysis was by 50g fire assay with AAS finish with the exception of cases where visible gold has been observed or a fire assay grade has exceeded 100 g/t or coarse gold is suspected then a screen fire assay (Au- SCR22AA) has been undertaken on those samples and those results reported instead of the fire assay result. |
|
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. 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). |
The RC drilling was undertaken using a face sampling percussion hammer using 137mm drill bits. The diamond drilling was undertaken using PQ3 (triple tube) and NQ3 (standard tube) techniques. The AC drilling was undertaken using a 75m blade bit and face sampling percussion hammer using 78mm drill bits. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Each metre of RC sample is checked, and an estimate of sample recovery is made. For this program, greater than 80% of samples had a recovery of 70% or higher. Sample weights reported by laboratory can also give an indication of recoveries. Drill core was measured and compared to drilled intervals and recorded as a percentage recovery. Recovery in oxidised rock can be reasonable whereas recovery in fresh rock is excellent. Each metre of AC sample is checked, and an estimate of sample recoveryis made. For |

| this program, greater than 80% of samples had a recovery of 70% or higher. Sample weights reported by laboratory can also give an indication of recoveries. |
||
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Drillers experience is important. Steady drilling, using modern well maintained drilling equipment, regular cleaning of cyclone and splitter, pausing the drilling at each metre to allow sample to pass through drill string and reducing sample loss. Using a RC rig equipped with auxiliary and booster compressors is critical to maintaining good RC sample recovery. Using professional and competent core drilling contractor minimises issues with sample recoveries through the use of appropriate drilling equipment techniques and drilling fluids suited to the particular ground conditions. |
|
| 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. |
RC sample recoveries from the mineralised zones are generally high although some of the weathered material is lost in drilling (dust) and some natural voids do exist. No sample was lost from 2-4 kg split from cyclone that was submitted for analysis, some loss of sample occurred from large green bags and some bias may have occurred to that sample as water was flowing from sample bag – this sample has not been analysed and therefore will not affect results reported in this release. The core sample recovery in the transitional and fresh rock zones is very high and no significant bias is expected. Recoveries in oxidised rock were lower. AC sample recoveries from the are generally high although some of the weathered material is lost in drilling (dust). Although no exhaustive studies have been undertaken, no significant bias is expected, and any potential bias is not considered material at this stage of resource development. |
|
| 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. |
Each RC metre drilled underwent detailed logging through the entire hole with record kept of colour, lithology, degree of oxidation, and type and intensity of alteration veining and sulphide content. Diamond core metres underwent detailed logging through the entire hole with record kept of colour, lithology, degree of oxidation, and type and intensityof alteration,veining |

| and sulphide content. Structural, density and geotechnical data is also collected on drill core. Each AC hole drilled underwent general logging through the entire hole with record kept of colour, lithology, degree of oxidation, and type and intensity of alteration veining and sulphide content. |
||
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
All logging is qualitative in nature and included records of lithology, oxidation state and colour with estimates of intensity of mineralisation, alteration and veining. Wet and dry photographs were completed on the core. |
|
| The total length and percentage of the relevant intersections logged. |
All drill holes were geologically logged in full (100%). |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
Core was half cut with a diamond saw with the same half always sampled and the other half retained in core trays. In some instances, oxidised and non- competent clay zones are carefully split in half using sampling wedge and sampled as half core. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
All RC sub-samples are collected via a cone splitter system mounted on the drill rig. An estimated 30% of samples were moist to wet in nature that passed through the cyclone – splitter system. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
All samples were analysed via a 50 gram fire assay. Following that analysis in cases where visible gold has been observed or a fire assay grade has exceeded 100 g/t or coarse gold is suspected then a screen fire assay (Au- SCR22AA) has been undertaken on those samples and those results reported instead of the fire assay result. Sample preparation and analysis were completed by ALS in Kalgoorlie. When received, samples are processed by code PREP-31 - logged in tracking system and bar code attached, wet samples dried through ovens, fine crushing to better than 70% passing 2mm, split sample using riffle splitter, split of up to 1000g pulverised to >85% sample passing 75um. |

| Quality control procedures adopted for all sub-sampling stages to maximise |
All sampling equipment and sample bags are kept clean at all times. |

| representivity of samples. | The RC drill rig mounted cone splitter is adjusted to ensure that the 1m split sample weighs on average between 2-4kg. The cone splitter is cleaned using an air nozzle after every drill rod – 6m. OzAurum Resources sampling procedures and QAQC is used to maximise representivity of samples. |
|
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. |
For drill core, the entire core is sampled at one metre intervals to ensure that samples are representative of the entire in-situ rock being tested. The laboratory ensures that the entire sample submitted is crushed and split appropriately to provide a representative sub- sample. No duplicate samples are taken from the core |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
The sample sizes (0.5 kg to 4 kg) are considered appropriate for the style of mineralisation at Mulgabbie North. Half cut PQ diamond core samples over 1m length (normally at the end of hole) were up to 4kg. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
The nature, quality and appropriateness of the assaying and laboratory procedures are industry standard for Archaean mesothermal lode gold deposits. The fire assay technique will result in a total assay result. In cases where visible gold has been observed or a fire assay grade has exceeded 100 g/t or coarse gold is suspected then a screen fire assay (Au-SCR22AA) has been undertaken on those samples and reported instead of the fire assay result. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
None of these tools are used | |
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision |
Certified Reference Materials (standards) are purchased from an independent supplier of such materials. Blanks are made up from samples previously collected from other drill programs at Mulgabbie North that have analysed as less than detection Au values. |

|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
At least two different company personnel visually verified intersections in the collected drill chips. At least two different company personnel visually verified intersections in the diamond core. A representative sample of each metre is collected and stored for further verification if needed. Drill core or core photos are used to verify drill intersections in diamond core samples. |
| The use of twinned holes. | The spatial location and assaying accuracy of historical drilling was confirmed with RC and DD twinned holes. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Data collected in the form of spread sheets, for drill hole collars, surveys, lithology and sampling. All geological and field data is entered into Microsoft Excel spreadsheets with lookup tables and fixed formatting (and protected from modification) thus only allowing data to be entered using the OzAurum geological code system and sample protocol. Data is verified and validated by OZM geologists and stored in a Microsoft Access Database Data is emailed to database administrator Geobase Australia Pty Ltd for validation and importation into the database and periodically into a SQL database using Datashed. |

| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
Initial hole collars surveyed by licenced surveyor DGPS (0.01m). Diamond drill line by surveyed back sight and foresight pegs. Dip was checked with clinometer on drill mast at set up on hole. RC holes are surveyed by down hole surveys at 30m intervals using single shot “Reflex Camera +/- 0.10 by drill contractor.

| Specification of the grid system used. | The grid system used is Geocentric Datum of Australia 1994 (GDA94). |
|
| Quality and adequacy of topographic control. |
Historical – Aerial photography used to produce digital surface topographic maps at 1:2500 1m contours. Topographic control is from an aerial photographic survey completed during 2018 with accuracy within 0.25m. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
Drilling at Mulgabbie North is at: 20m line x 10m hole 20m line x 20m hole 40m line x 20m hole The holes reported in this release were on 20m spaced lines that are 20m apart along the lines. |
| 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. |
The data spacing and distribution is sufficient to demonstrate spatial and grade continuity of the mineralised domains to support the current MRE classifications as Measured, Indicated and Inferred according to JORC (2012 Edition) reporting criteria. |
|
| Whether sample compositing has been applied. |
No sample compositing has been applied in the field within the mineralised zones. |
|
| 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. |
Diamond drill holes and RC holes were orientated 225°/-60° which is perpendicular to the shear zone hosting gold mineralisation and perpendicular to geology contacts. |
| 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. |
It is not believed that drilling orientation has introduced a sampling bias as the dominant mineralised shear zone at Mulgabbie North hosting mineralisation strikes at 315° and dips 70°NE. |

Please refer to table 1 in the report for full details. |
| If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Other relevant drill hole information can be found in Section 1-“Sampling techniques, “Drilling techniques” and “Drill sample recovery”. |
|
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. |
All one metre diamond drill results are reported in Appendix 1 Section 2 of JORC table 1. Holes include up to 2m of internal dilution - host unit was intersected in the 2m diluted section with significant alteration. A bottom cut-off grade of 0.1 g/t was used, and no top cut grade was applied. The procedure applied to the aggregate intercepts quoted is length weighted average (sum product of interval x corresponding interval assay grade), divided by sum of interval lengths and rounded by one decimal place. |
| 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 |

| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
These drill holes are designed to drill perpendicular to the Relief Shear that strikes at 315°. The dominant mineralisation geometries seen at the Mulgabbie North gold project are; 1. Shear zone hosted mineralisation on the lithological contact which strikes 315˚ and is moderately dipping to the east at -75°. The true width of mineralisation at the Mulgabbie North is reasonably well known from existing drilling and all drilling is designed to intersect the Relief Shear mineralised envelope at 90° or perpendicular to the strike of the Relief Shear. The -60° planned dip of all drill holes results in the true width being 70% of the downhole intersection. For example, a downhole intersection of 10m has a true width of 7m. |
| 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 (e.g. ‘down hole length, true width not known’). |
