Sabre Resources CEO, Jon Dugdale, commented:
“ The latest diamond drilling results reaffirm the potential of the deposit to host higher-grade nickel in massive and breccia matrix sulphide zones.
“Significantly, these higher-grade intersections are completely open towards the recentlydetected EM conductor extending west of the current nickel sulphide resource, which is the strongest surface conductor ever detected at the Sherlock Bay Project.
“Further drilling is now planned to extend this higher-grade sulphide mineralisation and test the massive sulphide potential of the strong EM anomaly to the west of this zone.
“The results provide clear scope to expand and upgrade the Sherlock Bay nickel-copper-cobalt resource. Sabre will now fast-track expansion of the resource as well as upgrading development studies to take advantage of the increased global demand for ‘future facing’ battery metals.”
Western Australian nickel-sulphide focused explorer/developer Sabre Resources Ltd (ASX: SBR) is pleased to announce high-grade assay results from the initial two diamond drillholes at the western end of the Sherlock Bay nickel-copper-cobalt sulphide deposit, located in the northwest Pilbara region of Western Australia (see plan view location, Figure 1 and longitudinal projection, Figure 2).
These latest results include high grades associated with the massive and breccia matrix sulphide zone (see Image 1) intersected by SBDD002[1] of 1.18% nickel equivalent (NiEq) with significant associated copper, cobalt and platinum-palladium-gold (3E) grades* .
The latest results produced significant higher-grade sulphide intersections, extending the western/down-plunge extent of the sulphide deposit , which include in SBDD002:
-
11.8m @ 0.54% NiEq* (0.43% Ni, 0.09% Cu, 0.02% Co, 0.13 g/t 3E) from 414m (SBDD002)
-
incl. 6.0m @ 0.75% NiEq* (0.62% Ni, 0.14% Cu, 0.03% Co, 0.11 g/t 3E) from 419m incl. 1.0m @ 1.18% NiEq* (1.02% Ni, 0.16% Cu, 0.05% Co, 0.10 g/t 3E) from 422m
Results from the shallower, thick, semi-massive and stringer sulphide zone in SBDD001[2] , on the same cross section (19,620mE - see Figure 3), also produced a substantial intersection of :
-
33.0m @ 0.50% NiEq* (0.42% Ni, 0.08% Cu, 0.02% Co, 0.08 g/t 3E) from 296m (SBDD001)
-
incl. 21.0m @ 0.55% NiEq* (0.46% Ni, 0.08% Cu, 0.02% Co, 0.09 g/t 3E) from 306m
incl. 5.0m @ 0.66% NiEq* (0.53% Ni, 0.12% Cu, 0.02% Co, 0.26 g/t 3E) from 322m
These new nickel sulphide intersections are outside and to the west of the Discovery resource zone at Sherlock Bay, which remains completely open to the west where the strongest surface EM anomaly detected to date is located[4] (see Figure 1). This highlights the strong potential for further massive sulphide discoveries in this exciting new and untested target zone .
A high-priority diamond drilling program is now planned to expand the resource potential to the west of the SBDD001 and SBDD002 intersections, as well as test the new, strong, surface EM anomaly.
The new drilling program aims to expand the higher-grade resource potential of the Sherlock Bay deposit prior to further metallurgical and development studies to determine the economic potential of this major nickel-copper-cobalt sulphide deposit .
*see Appendix 1 for nickel equivalent (NiEq%) calculations.

Figure 1: Sherlock Bay new drilling locations and surface EM anomalies extending west of the latest intersections
The strong C3 DHEM anomaly associated with the massive and breccia matrix sulphides intersected by SBDD002, extends to the east of the hole and was tested with the third hole of the program, SBDD003A[3] (see cross section, Figure 3, below). Results are pending for this hole which intersected 15m of massive, breccia matrix and stringer sulphides within an overall 40m intersection of sulphide mineralisation (see Appendix 2 for sulphide mineralisation descriptions in SBDD003A[3] ).
The massive and matrix breccia sulphide zones intersected - and the consistent nickel, copper, cobalt, as well as the platinum-palladium grades - are typical of mafic-intrusive associated deposits such as the Andover nickel sulphide discovery of Azure Minerals Ltd (ASX:AZS), located 60km along strike to the west of Sherlock Bay (see location, Figure 4), which includes a recently announced Mineral Resource estimate of 4.6Mt @ 1.41% NiEq (1.11% Ni, 0.47% Cu, 0.05% Co)[5] , (Azure Minerals Ltd (ASX:AZS) 60% interest and internationally-renowned prospector Mark Creasy 40% interest) [5] .
The significant thicknesses of massive, breccia matrix and stringer sulphide mineralisation intersected by drillholes SBDD003A[3] and SBDD005[6] from the Discovery Zone (see Figure 2) have been submitted for analysis. Drillhole SBDD004[6] from the Symonds Zone (see Figure 2) is currently being logged and processed for sample submission. Significant results will be reported when available.
Refer to Table 1 for drillhole details and Table 2 for significant intersections. Appendix 3 shows JORC Table 1, Sections 1 and 2.

Sherlock Bay Nickel Project and the current drilling program:
The Sherlock Bay nickel-copper-cobalt project is located 50km east of Roebourne in Western Australia’s highly-prospective Pilbara region (see location, Figure 4 below).
==> picture [482 x 377] intentionally omitted <==
Figure 4: Sherlock Bay Nickel-Copper-Cobalt Project, regional geology and location plan
The current JORC 2012 Mineral Resource for Sherlock Bay is 24.6Mt @ 0.40% Ni, 0.09% Cu, 0.02% Co (0.45% NiEq) containing 99,200t Ni, 21,700t Cu, 5,400t Co (117kt NiEq ), including Measured: 12.48Mt @ 0.38% Ni, 0.11% Cu, 0.025% Co; Indicated: 6.1Mt @ 0.59% Ni, 0.08% Cu, 0.022% Co and Inferred: 6.1Mt @ 0.27% Ni, 0.06% Cu, 0.01% Co [7] .
Sabre completed a Scoping Study[8] on the Sherlock Bay nickel sulphide deposit in January 2022 which highlighted significant cash-flow potential at a nickel price of US$10/lb (US$22k/t). The nickel price has since increased by over 25% to around US$12.50/lb (US$28k/t) (see Kitcometals.com). The Company confirms that it is not aware of any other new information or data that materially affects the information in the Scoping Study release of 27[th] January 2022[8] .
The recently-completed 2,387m diamond drilling program targeted higher grade to massive nickel (copper, cobalt) bearing sulphides at the projected intersection of the sulphide mineralised horizon with the contact of the Sherlock (mafic-ultramafic) Intrusion.
The program was co-funded by the WA Government for up to 50% of drilling costs, and $10,000 mobilisation costs, capped at a total of $220,000[9] .
*see Appendix 1 for nickel equivalent (NiEq%) calculations.

==> picture [595 x 87] intentionally omitted <==
The location of the Sherlock Intrusive was indicated by gravity survey results to be at depth and on the southern side/contact of the Sherlock Bay mineralised horizon. This has been confirmed by drilling in SBDD002[1] and SBDD003A[3 ] which intersected mafic intrusive rocks to the east of the mineralised horizon and which continued to intersect massive, breccia matrix and stringer sulphides at the base/contact of the Sherlock Intrusive gabbro sill, associated with a strong DHEM conductor[1] (C3) (Figure 3).
The association between the Sherlock Bay sulphide deposit and the Sherlock Intrusive, together with the ‘typical’ nickel, copper, cobalt, as well as the platinum-palladium ratios confirm that Sherlock Bay is an intrusion-related Ni-Cu-Co-PGE sulphide deposit. The sulphide deposit is analogous to other, major deposits in WA such as the Nova Bollinger deposit of IGO Ltd (ASX:IGO), which had an initial Mineral Resource of 14.3 Mt @ 2.3% Ni, 0.9% Cu, 0.08% Co[6] , and the Julimar deposit of Chalice Mining Ltd (ASX:CHN) which has a Mineral Resource of 350Mt @ 0.16% Ni, 0.10% Cu, 0.015% Co, 0.94g/t Pd+Pt+Au (3E) (0.58% NiEq)[11] .
About Sabre Resources:
Sabre Resources is an ASX-listed company (ASX:SBR) focused on the exploration and development of a highly-prospective portfolio of nickel sulphide and gold assets in Western Australia, and uranium and base metal prospects in the Northern Territory.
The Company’s flagship project is the Sherlock Bay nickel-copper-cobalt project[8] – a significant nickel sulphide deposit in Western Australia’s highly prospective Pilbara Region (Figure 4). Sabre is also earning an 80% interest in the Sherlock Pool[12] tenement E47/4345 (Figure 4), which covers immediate strike extensions to the northeast and southwest of Sherlock Bay.
The Company is also earning 80% of the Nepean South tenement which covers a >10km corridor of prospective ultramafic rocks south of the Nepean Nickel Mine (past production 1.1Mt at 3.0% Ni[13] ). A recently completed RC drilling program intersected high nickel grades with elevated copper (e.g., 8m @ 1.01% Ni, 0.02% Cu from 28m incl. 3m @ 1.26% Ni in NSRC0012)[13] in saprolite across a 200m wide zone that overlies the ultramafic sequence. Deeper drilling intersected disseminated sulphides across ultramafic/footwall basalt contact. Results of up to 4m @ 0.20% Ni, 28.4% MgO at end of hole (134-138m) in NSRC0004 have confirmed channelised ultramafics with potential for Kambalda/Nepean style massive nickel sulphide accumulations. A surface fixed loop electromagnetic (FLEM) program is in progress, targeting massive nickel-sulphide targets for further drill testing.
Sabre has an 80% interest in three recently granted exploration licences at Cave Hill[14] , covering a >50km strike length of interpreted extensions to the Nepean and Queen Victoria Rocks nickel sulphide belts , adjoining the Nepean South tenement.
Sabre’s 100% owned Ninghan Gold Project[15] in Western Australia’s southern Murchison district is located less than 20km along strike from the Mt Gibson gold mine, which has a ~3Moz gold resource endowment[10] . Previous RAB and aircore drilling has defined two strongly anomalous zones of gold-arsenic mineralisation at Ninghan where follow-up drilling is planned.
In the Northern Territory, Sabre holds an 80% interest in the Ngalia Uranium-Vanadium Project[14] , which comprises two granted exploration licences, Dingo EL32829 and Lake Lewis EL32864, in the highly-prospective Ngalia Basin near existing uranium resource projects.

*Cautionary note regarding visual estimates:
In relation to the disclosure of visual mineralisation in the table above, the Company cautions that visual estimates of sulphide mineralisation material abundance should never be considered a proxy or substitute for laboratory analyses. Laboratory ICP-MS and ICP-OES analyses are required to determine widths and grade of the elements (e.g., nickel – Ni and/or copper - Cu) associated with the visible mineralisation reported from preliminary geological logging. The Company will update the market when laboratory analytical results are received and compiled.

Appendix 3: JORC Code, 2012 Edition – Table 1 (Sherlock Bay Project) Section 1 Sampling Techniques and Data
| 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. • 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 (e.g., submarine nodules) may warrant disclosure of detailed information. |
• RC drilling was conducted using a 5 ¼” face sampling bit on a nominal 20m by 60 m spacing. • RC samples were collected in large plastic bags from riffle splitter and a 2-5 kg representative sample taken for analysis. • Diamond drilling was sampled to geological contacts then at 1 m or maximum 1.5m intervals with quarter core samples taken for analysis. • Collar surveys were carried using total station electronic equipment. • Down hole surveys for each historical hole were completed using single shot cameras. • Current diamond drillholes being surveyed using gyro electronic multi-shot. • Sampling was limited to the visually mineralised zones with additional sampling of several metres either side of the mineralisation. |
| 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 majority of RC drilling was completed in 2004 and 2005 by Sherlock Bay Nickel Corporation (SBNC) using face sampling equipment. • Core drilling included historic holes completed in the 1970’s by Texas Gulf as well as a substantial number of holes completed in 2005 by SBNC. • Current holes are HQ diamond with reduction to NQat depth/in case of difficult drilling. |
| 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. |
• Drill core recovery was measured and was generally excellent. • No record of RC sample quality was located, however drilling conditions were good and samples generally from fresh rock and no problems were anticipated. • No obvious relationships between sample recovery and grade. |
| 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 isqualitative orquantitative |
• All holes were/are logged in the field at the time of drilling. • No core photographs were located from historical holes. • Current diamond drillholes are being routinely photographed. |

| in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• Entire holes are being logged. • Specific gravity (SG) and magnetic susceptibility measurements on selected intervals. |
|
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core 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. |
• 1m RC samples were split by the riffle splitter on the drill rig and sampled dry. • The sampling was conducted using industry standard techniques and were considered appropriate. • No formal quality control measures were in place for the programs. • Current drilling will include registered standards and duplicates and blanks every 25m/50m. • Sample sizes appropriate for the grain size of the sulphide 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) and precision have been established. |
• Historic drill samples were assayed using four acid digest and AAS analysis at accredited laboratories. • Samples from the 2004 and 2005 programs were assayed using four acid digest and AAS analysis at the Aminya and ALS laboratories. • QAQC data was limited to assay repeats and interlaboratory checks which showed acceptable results. • Current holes will be samples at approximately 1m intervals and samples of quarter core to half core analysed by Intertek laboratories, Perth via four acid digest and ICP-MS / ICP-OES analysis. |
| 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. |
• Field data was loaded into excel spreadsheets at site. • Original laboratory assay records have been located and loaded into an electronic database. • Hard copies of logs, survey and sampling data are stored in the SBR office. • No adjustment to assaydata. |
| 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. |
• SBNC drill hole collars were accurately surveyed using electronic total station equipment. • A local grid system was used with data converted to WGS84. • Topography is very flat with control from drill hole collars and field traverses. |

|---|---|---|
| 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. |
• Drilling was on a nominal 20m by 60m spacing in the upper 200m of the deposit. • Deeper mineralisation was tested at approximately 120m spacing. • Drill data is at sufficient spacing to define Measured, Indicated and Inferred Mineral Resources. • Samples were composited to 2 m intervals for estimation. |
| 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. |
• Shallow holes were drilled at approximately - 60ointo a vertical trending zone and orientated perpendicular to the known strike of the deposit. • Deeper diamond holes flattened to be approximately orthogonal to the dip of mineralisation. • No orientation-based sampling bias has been identified in the data. |
| Sample security |
• The measures taken to ensure sample security. | • Samples were organised by company staff then transported bycourier to the laboratory. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. |
• Procedures were reviewed by independent consultants during the exploration programs in 2005 bySBNC. |
Section 2 Reporting of Exploration Results

|---|---|---|
| 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 license to operate in the area. |
• The deposit is located on granted mining lease M47/567 with an expiry date of 22/9/2025. • SBR has a 70% beneficial interest in the project. |
| Exploration done by other parties |

have been historically reported. | |
| 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. |
• Length weighted average grades have been reported. • No high-grade cuts have been applied. • Metal equivalent values are not being 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’). _ |
• The majority of holes have been drilled at angles to intersect the mineralisation approximately perpendicular to the orientation of the mineralised trend. • Some steeper holes will have intersection length greater than the true thickness. |
| 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. |
• A relevant plan showing the historical drilling is included within the_Sabre Resources Ltd_ announcement_of_12th June 2018 “Resource Estimate Update for the Sherlock Bay Nickel- Copper- Cobalt Deposit”. • Representative longitudinal projection and cross sections are shown on Figure’s 2 and 3. Location and tenement outlines are shown on Figure 4. |
| Balanced Reporting |
• 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. • 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 relevant results available have been previously reported. |
