Codrus Secures Large-Scale, Niobium-Rich, HighGrade REE Project in WA
Outstanding opportunity to explore for high-grade permanent magnet REE’s in a Tier-1 location
Highlights:
-
Agreement to earn up to 90% of the Karloning Rare Earth Element (REE) Project , located in WA’s Wheatbelt, 260km north-east of Perth.
-
The project has demonstrated the presence of high-grade and high-value permanent magnet rare earths Dysprosium, Neodymium, Terbium and Praseodymium in xenotime within a large-scale pegmatite.
-
The pegmatite system also hosts significant niobium , a critical metal used in the steel industry with applications including wind turbines and high-performance batteries.
-
Grab samples have returned high-grade assays including:
-
>5,740ppm (>0.57%) Dysprosium Oxide – Dy2O3 (over detection limit, assays awaited)
-
2,658ppm (0.27%) Neodymium Oxide – Nd2O3
-
3,516ppm (0.35%) Terbium Oxide – Tb4O7
-
235ppm Praseodymium Oxide – Pr6O11
-
>5,000ppm (0.5%) Niobium (over detection limit, assays awaited)
-
The large-scale pegmatite system at Karloning is estimated to be up to 1.5km long and up to 200m wide.
-
Codrus has pegged additional tenure adjacent to the south-west boundary of the Karloning Joint Venture tenement, which encompasses potential extensions to the pegmatite system
-
The deal provides Codrus with a low-cost, simple and staged approach to earn up to a 90% interest in the Karloning Project.
-
The Project provides an outstanding opportunity for Codrus to diversify into the critical minerals space and build on its current gold and copper assets by securing exposure to a commodity sector with outstanding fundamentals and a strong growth outlook.
-
The Project, which is located approximately 30km north of Mukinbudin in the Western Australian wheatbelt, has historically been quarried for feldspar and quartz.

Codrus Minerals (ASX: CDR , Codrus or the Company ) is pleased to advise that it has secured an exciting growth and diversification opportunity in the rare earths sector after entering into a farm-in and joint venture agreement with Talgomine Minerals Pty Ltd (Talgomine) to earn up to a 90% interest in the Karloning Rare Earth Element (REE) Project , located in Western Australia’s Wheatbelt.
The Project, which is located 30km north of the regional town of Mukinbudin and 260km north-east of Perth (see Figure 1) , provides Codrus with an opportunity to explore for the high-value rare earth elements (REE) used in the manufacture of high-strength permanent magnets – namely praseodymium, neodymium, terbium and dysprosium.
These elements are in high demand because of the explosive growth in industries that rely on permanent rare earth magnets such as Electric Vehicles, wind turbines and other renewable energy applications.
While these permanent magnet REE’s are the key high-grade values returned in the grab samples, significant grades of other rare earths, tantalum and niobium were also observed (see Table 1) .

Codrus Managing Director, Shannan Bamforth, said: “This is an exceptional opportunity for Codrus to secure a majority interest in a highly prospective REE project in a Tier-1 location just two-and-a-half hours’ drive from Perth. We secured this opportunity as part of our ongoing business development activities to add further depth to our existing portfolio of gold projects in Australia and the USA. We are attracted to the rare earths sector because of its strong fundamentals and the relative scarcity of quality exploration opportunities.
“The Karloning pegmatite is located in an existing quarry, providing us with a unique opportunity to see the geology and make a rapid assessment of the exploration potential. We believe the pegmatite has significant scale, and grab sampling has returned impressive grades of the four key REE’s required in the manufacture of permanent rare earth magnets.
“This is a walk-up exploration opportunity, and we are looking forward to getting on the ground as soon as possible to commence initial exploration activities with a view to firming up targets for drilling in early 2023.”
The Karloning Project
The Karloning Project can be easily accessed by sealed roads via the town of Mukinbudin.
The geology within the tenements (E70/5339 and E70/6306 (pending)) comprises mainly medium to coarse grained biotite granite and adamellite with a large quartz-microcline pegmatite, known as the Karloning Pegmatite (see Figure 2) .

Tertiary lateritic duricrusts skirt the granite outcrops and are eroded by the Quaternary paleo drainages forming broad sheetwash areas consisting of sands, clays, and silts. Mapping by the Geological Survey of

Western Australia (1:250,000 Perth map sheet) shows a strike extent of ~1.5km for the Karloning Pegmatite, and Codrus believes there is a potential significant extension to the pegmatite beneath cover and for multiple pegmatite horizons to be discovered on the project (see Figure 3) .

Figure 3. Karloning Project location showing the location of the mapped Karloning Pegmatite (red) and potential extensions by way of extending the known occurrence and identifying multiple horizons on the property (yellow), based on GSWA geophysical and radiometric data.
A quarry has been operated at the site historically (E70/5339) focused on the production of feldspar and quartz for industrial purposes (see Figure 4).
The pegmatite has had minor historic soil sampling completed to the north and west of the quarry which identified anomalous (+250ppm) total rare earths and Yttrium (TREY). The quarry area was subject to shallow (maximum depth 21.3m) vertical rotary air blast drilling (RAB) in the 1970s that only assessed presence of quarry target minerals quart and feldspar, with no analysis for REE’s.
Due to the shallow and very restricted nature of the drilling, the geometry of the Karloning Pegmatite remains poorly constrained.

The mineralisation seen in the surface outcrop of the quarry was dominated by xenotime with minor fergusonite hosting the REE and minor columbite and tantalite (see Figure 5 & 6) .
It is very encouraging for this early-stage sampling in the quarry to demonstrate the presence of the highvalue permanent magnet rare earths Dysprosium, Neodymium, Terbium and Praseodymium.

Planned Work Programs
Initial planned work programs at the site include completing either drone or ground magnetics and ground radiometric surveys as a priority. Soil sampling across the tenement package will be completed at 100m line spacing with 50m sample spacing along the lines.
The results of these surveys will underpin the maiden drilling program, planned for Q1 CY2023, which will focus on defining the extents of the pegmatite and primary controls on the distribution and continuity of REE mineralisation.
Work will commence on the JV ground as soon as is practicable and on the 100% CDR tenement as soon as the tenement is granted.
Talgomine Agreement
The key terms of the farm in and joint venture agreement between Codrus and Talgomine, the owner of the Karloning Project, are:
-
Within 7 days, Codrus must pay Talgomine $30,000 cash and issue $30,000 worth of Codrus shares at a 10-day VWAP (approximately 430,000 shares at $0.07).
-
Codrus will grant Talgomine 1,000,000 options when it has met the minimum expenditure of $100,000, with an exercise price of $0.20 with a 2-year expiry from the date of issue.
-
Codrus will grant Talgomine 2,500,000 options when it has earnt a participating interest of 70% (by spending an additional $300,000), with an exercise price of $0.50 with a 2-year expiry from the date of issue.
-
The shares and options to be issued to Talgomine, will be issued under existing ASX Listing Rule 7.1 placement capacity.
-
Once Codrus has earnt a 70% interest, Talgomine can contribute to the joint venture or be freecarried to DFS. If it is free-carried then Codrus’ participating interest will increase to 85%.
-
When Codrus increases from 70% to 90% interest there is no additional consideration payable to Talgomine.
-
On completion of a DFS, Talgomine can contribute to the joint venture or be free-carried to the commencement of mining production (to be repaid to CDR at a rate equal to the then current London Inter-Bank Offered Rate plus 2.5% of Talgomine’s 100% entitlement to revenue received from the project. If free-carried then Codrus’ participating interest increases to 90%.
Standard farm-in and joint venture terms are referenced in the agreement.

JORC Code, 2012 Edition – Table 1 report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| 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. • 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 (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 (eg submarine nodules) may warrant disclosure of detailed information. |
•Fourteen rock grab samples were collected by suitably qualified Codrus Minerals geologists from in-situ and float material within the Karloning quarry, •The samples were typically 1-2kg each, field checked for indicator elements such as yttrium with an Olympus Vanta hand held portable XRF, and submitted to ALS Geochemistry, Perth for preparation and assay by lithium metaborate fusion with ICPAES finish (ME-MS81h). |
| 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). _ |
•Not applicable – no drilling was carried out. |
| 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. |
•Not applicable – no drilling was carried out. |
10
==> picture [50 x 63] intentionally omitted <==
| Logging | • Whether core and chip samples have been geologically and | •Not applicable – no drilling samples were logged. |
| 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 andpercentage of the relevant intersections logged. |
•Geology, alteration, and structure were recorded at selected sample sites; the field record is qualitative in nature. |
|
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all cores taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality, and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages 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. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
•Not applicable – no drilling was carried out. •Not applicable – no drilling was carried out. •Sample preparation follows industry standard best-practice. Samples were dried, crushed (2mm) and rotary divided where required. Pulverisation was done by LM1 mill, and bowls were barren-washed after each sample. •No sub-sampling undertaken on assayed samples. No field duplicates collected as samples were taken for indications of mineralisation only. The sampling was of reconnaissance nature to verify the presence and nature of rare earth element mineralisation within the Karloning Pegmatite and can not be considered representative of in situ grades or in any way suitable for resource estimation. •Sample sizes of greater than 1kg are considered appropriate for the style of mineralisation. |
| 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. • 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. • 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) andprecision have been established. |
•At ALS Perth the rock chip grab samples were oven dried at 60° C, pulverised to P85 -75 microns and assayed by ALS Perth’s ME-MS81h method. •One commercial reference standard was included in the submissions; the laboratory also utilized internal standards. •The standards returned satisfactory assay results. |
11
==> picture [50 x 63] intentionally omitted <==
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• Sampling was conducted by suitably qualified Codrus Minerals geologists, the reported REE grades agree with observed minerology verified on site using an Olympus Vanta portable XRF. • Not applicable – no drilling. • Primary data was collected into a spread sheet and was loaded into the Company database. Adjustments made to the assay data were limited to the conversion of reported elemental assays for their equivalent rare earth oxides. In all instances the original elemental data were stored in the database and the equivalent oxide values were tagged as calculated values; random checks on the calculated fields returned no issues. The oxides were calculated from the element according to the following element to oxide conversion factors: CeO2 (1.228), Dy2O3 (1.148), Er2O3 (1.143), Eu2O3 (1.158), Gd2O3 (1.1523), Ho2O3 (1.146), La2O3 (1.173), Lu2O3 (1.137), Nd2O3 (1.166), Pr6O11 (1.208), Sm2O3 (1.16), Tb4O7 (1.176), Tm2O3 (1.142), Y2O3 (1.27), Yb2O3 (1.139). Ratios of each oxide to Total Rare Earth Oxides (TREO) are used to determine the percentages of heavy (HRE), light (LRE) and magnetic (MRE)rare earthoxides. |
| 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. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• Measurement points were located with a handheld GPS with an accuracy of +/- 5 metres. • All coordinates and maps presented here are in the MGA Zone 50 GDA94 system. • Not applicable at this stage of the exploration. |
| 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. |
• Not applicable – no drilling was carried out. • The rock sampling was of a reconnaissance nature to verify the presence and nature of rare earth element mineralisation within the Karloning Pegmatite and can not be considered representative of in situ grades or in any way suitable for resource estimation. Significant further work will be needed to determine in situ REE grades • Not applicable |
12
==> picture [50 x 63] intentionally omitted <==
| 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. |
• The rock sampling was of reconnaissance nature to verify the presence and nature of rare earth element mineralisation within the Karloning Pegmatite and can not be considered representative of in situ grades or in any way suitable for resource estimation. The coarse nature of the observed mineralisation as shown by figures in this announcement point to a significant “nugget” effect with the REE mineralization. • At this stage geometry, zonation, extents and in situ REE grade of the Karloning Pegmatite remain very poorly defined. |
| Sample security |
• The measures taken to ensure sample security. | • The chain of custody of the samples, starting from sample collection up to delivery of the samples to ALS Laboratory was managed by Codrus Minerals personnel. Sample numbers were unique and without location information. The level of security is considered appropriate for such a sampling exercise. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. | • External audits or reviews have not been conducted at this stage. |
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The sampling was entirely conducted within granted exploration licence E70/5339 together with the tenement holder (Talgomine). • The tenement is in good standing, without known impediments. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. | • Most of the previous owners and explorers efforts were focused on the quarrying of feldspar and quartz from the Karloning pegmatite as aggregate products saleable to the construction industry and not relevant to the Codrus Minerals’ exploration interests. Details of 20 RAB holes drilled vertically to a maximum depth of 21.3m have been collated with analysis only completed for Na2O and K2O • Kinloch Resources completed a partial soil survey over the area (144 samples) in the 2011-2012 period and samples were analysed by ACME labs, Vancouver for REEs using a Lithium Metaborate fusion and ICP- MS finish. This work showed multiple soil anomalous zones with >1000ppm TREEs over the northern part of the Karloning Pegmatite as mapped by the GSWA. Other than this work by Kinloch the Karloning Pegmatite does not appear to have been evaluated in any systematic way for REEs |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Geology | • Deposit type, geological setting, and style of mineralisation. | • The tenement encompasses the Karloning Pegmatite, an NYF type pegmatite which is typically zoned from biotite adamellite through graphic granite the margins, transitioning into albite zone (with biotite veins and aplite dikes) and a quartz core. The reconnaissance rock sampling announced here shows potentially significant REE mineralization within at least the graphic and albite zones of the Karloning Pegmatite. |
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevation above sea level inmetres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole length.• 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 o explain why this is the case. |
• Not applicable – no drilling was carried out. |

| 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. • 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 clearly stated. |
•None applied or considered necessary for the style of sampling undertaken. •Not applicable. •No metal equivalents reported. |
| 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 (e.g., ‘down hole length, true _width not known’). _ |
•Not applicable – no drilling was carried out and the geometry of the pegmatite is not currently known. |
| 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 are included in this report. |
| 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 avoiding misleading reporting _of Exploration Results. _ |
•The rock sampling was of reconnaissance nature and all Codrus Minerals rock sample assay results are reported. |
| 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. |
•The results are considered indicative only of the mineralisation in the area. •Geological observations and relevant photographs of the mineralisation style are included in this report |
| Further work | • The nature and scale of planned further work (e.g., 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 commercially sensitive. |
•Follow-up work to better define the extent of the REE mineralisation and host Karloning Pegmatite is planned and expected to include detailed magnetic and radiometric surveying, and detailed soil sampling. This work will be used to plan trenching and/or drilling to delineate the identified REE mineralisation •Extent of the Karloning Pegmatite is currently poorly constrained and |
