Reverse Circulation (RC) Drilling – Program Overview
A total of 37 RC holes were completed across five of the Company’s 100%-owned projects in the Central Goldfields for a total of 3,851m. Drilling was completed between late January and early March 2023. Drill hole collar details are included below in Appendix 1 . All assay results have now been received. The JORC Table 1 outlining the RC drilling and sampling procedures is included as Appendix 2 .
The RC drill program was designed to test a variety of geochemical, geophysical and structural targets defined in 2022, for Archaean shear-hosted gold systems and Volcanogenic Massive Sulphide (VMS) base-metal deposits.
Victor Bore RC Drilling Results
A total of 16 RC drill holes were completed at the Victor Bore Project on tenements M37/1349 and P37/8376. The Victor Bore project lies adjacent to the Kailis Gold Mine held by Northern Star Resources Limited (see Figure 1 ).
The 2023 RC drilling at Victor Bore tested several NE-trending structural zones containing quartz veins at surface. Shallow historical workings are located along all of the structural zones drill tested. The main structural zone at the northern end of M37/1349 extends approximately 400m along strike. Assay results were previously reported in Infinity’s ASX Announcement dated 4 April 2023[1] . The 2023 RC drilling results returned several significant gold intercepts, including:
-
7 m @ 1.96 g/t Au, from 32 m depth in hole VB23RC004. ➢ including 1 m @ 8.67 g/t Au , from 34 m depth.
-
6 m @ 1.40 g/t Au, from 25 m depth in hole VB23RC005. ➢ including 1 m @ 7.33 g/t Au , from 29 m depth.
-
3 m @ 2.39 g/t Au, from 72 m depth in hole VB23RC006. ➢ including 1 m @ 6.82 g/t Au , from 72 m depth.
-
8 m @ 3.46 g/t Au, from 56 m depth in hole VB23RC0010. ➢ including 1 m @ 21.86 g/t Au , from 57 m depth.
-
4 m @ 2.65 g/t Au, from 43 m depth in hole VB23RC012. ➢ including 2 m @ 4.84 g/t Au , from 43 m depth.
A total of 13 of the 16 holes at Victor Bore returned anomalous assays over 1 g/t Au, with a maximum 1 m assay of 21.86 g/t Au in hole VB23RC010. Significant gold intercepts are shown below in Table 1 (0.1 g/t Au cut-off grade).
A drill hole map showing all 16 RC holes at Victor Bore is included below on Figure 2 . Two cross-sections (A-B and C-D) across the main NE-trending mineralised zone on M37/1349 are included as Figures 3 and 4 , highlighting the steeply SE-dipping interpreted zones of gold mineralisation at Victor Bore, which are open at depth.

Great Northern RC Drilling Results
The Great Northern project lies approximately 30 km east of Leonora (see Figure 1 ). The most recently drilled RC holes were designed to follow-up a 12-hole RC drilling program completed in 2022, which returned several significant gold intercepts (see Infinity ASX Announcement dated 25 March 2022[2] ).
A total of five RC drill holes were completed in 2023 at the Great Northern Project on tenement P37/8310. The 2023 RC drilling results returned some significant gold intercepts, with a maximum 1m assay of 7.49 g/t Au in hole GN23RC112. Significant gold intercepts are shown below in Table 2 (0.1 g/t Au cut-off grade). A drill hole map showing the location of all drill holes at Great Northern is shown below on Figure 5 , including 11 drill holes completed by Melita in 1987, 12 RC holes completed by Infinity in 2022 and the five new RC holes completed by the Company in 2023.
Holes GN23RC112 and GN23RC113 were designed to test below the previous holes drilled by Melita in 1987 and those drilled by Infinity in 2022, to verify if gold mineralisation continues at depth. Both drill holes returned significant intercepts indicating that the gold mineralisation is still open at depth.
A SW-NE cross-section through the central part of the Great Northern gold mineralisation is included on Figure 6 , which shows that the NE-dipping gold-bearing zone of mineralisation is open at depth. A 3D interpretation of this gold system is underway, which will help design the next stage of drilling. The drilling to date has only tested mineralisation to shallow depths (maximum 80m), therefore further deeper drilling is well justified.

Barlow’s Gully RC Drilling Results
A total of nine RC drill holes were completed at the Barlow’s Gully Project on tenement P37/8278. The project lies within an Archaean greenstone belt along the Ursus Fault Zone, which is also host to several significant gold deposits along strike to the SSE, such as King of the Hills and Kailis (see Figure 1 ).
The 2023 RC drill holes were designed to test gold-bearing surface geochemical anomalies defined in 2022 (see Infinity ASX Announcement dated 30 June 2022[3] )
The 2023 RC drilling results returned some significant gold intercepts, with a maximum 1 m assay of 3.54 g/t Au in hole BG23RC003. Significant gold intercepts are shown below in Table 3 (0.1 g/t Au cut-off grade). A drill hole map showing the nine RC holes from 2023 is included below on Figure 7 .

Coppermine
The Coppermine Project (P37/9162) is located 5km southwest of Red 5 Limited’s 4.12Moz King of the Hills gold mine (see Figure 1 ). The Coppermine project is prospective for Volcanogenic Massive Sulphide (VMS) base-metal deposits and Archaean shear-hosted gold systems.
A small malachite copper-stained gossan and associated narrow quartz vein has been historically mined to a depth of several meters and returned anomalous surface rock chip sample assays up to 20642 ppm Cu (2.06% Cu), 3791 ppm Zn and 0.33 ppm Au. The gossan is also associated with a drone magnetic target (see Infinity ASX Announcement dated 4 August 2022[4] ).
A total of 3 RC drill holes were completed at the Coppermine Project, designed to test the drone magnetic target and area of the surface gossan. The 2023 RC drilling results returned a maximum 1m RC sample of 0.45% Cu from 1415m in hole CM23RC003, which was designed to test directly underneath the gossan. This interval also returned anomalous zinc (0.2% Zn) and gold (0.17 g/t Au). There were no other anomalous results in the other two drill holes.
The drone magnetic high anomaly was explained by the intersection of highly magnetic ultramafic rocks encountered in the drill holes. Infinity is assessing the potential to undertake a geophysical exploration survey later this year, which will be designed to test the wider tenement area for VMS-style copper-zinc sulphide mineralisation.
Camel
The Camel Project (P37/8325) lies ~8km north of Leonora and 6km northeast of the Kailis Gold Deposit (see Figure 1 ). Camel is prospective for Archaean shear-hosted gold systems and hosts a number of old gold workings. Historical RC drilling at Camel in 1986 returned some anomalous gold, with intercepts up to 5m @ 2.24 g/t Au. A linear drone magnetic target was also defined by Infinity in 2022 (see Infinity ASX Announcement dated 1 September 2022[5] ).
A total of four RC drill holes were completed at Camel, designed to test the linear drone magnetic target and below some of the old gold workings. Recent RC drilling results returned a maximum 1m RC sample of 0.41 g/t Au from 55m depth in hole CA23RC001. While there were no significant intercepts of greater than 1g/t Au in recent drill holes, some wide zones of low-grade gold >0.1 g/t Au were intersected, including 14m @ 0.19 g/t Au in hole CA23RC003. Further RC drilling will be considered at a later stage, as a secondary priority to other projects in the Central Goldfields.
Craig’s Rest and Chicago
RC drill holes were designed at Craig’s Rest but have not been drilled yet as the project awaits Cultural Heritage clearance, which is proposed for later this year. Craig’s Rest is a high-priority project which has returned highlyanomalous rock chip samples up to 37.64 g/t Au (see Infinity ASX Announcement dated 21 September 2022[6] ).

News release
Craig’s Rest is also host to several previous drilling programs that reported high-grade drill assays and significant gold intercepts including 5 m @ 57.9 g/t Au (see Infinity ASX Announcement of 12 October 2022[7] ). The planned drilling will test a range of targets, including following up the most significant intercepts returned from previous drilling.
RC drill holes were designed at Chicago in early 2023 and will be drilled pending Cultural Heritage clearance, anticipated for later this year. Rock chip samples from Chicago undertaken in 2022 returned anomalous assays up to 2.37 g/t Au, proximal with two drone magnetic targets defined by Infinity in 2022 (see Infinity ASX Announcement dated 19 September 2022[8] ). The planned drilling will test a range of targets and also test underneath the old workings.
Next Steps
All drill hole data acquired to date from the Central Goldfields is currently being interpreted by Infinity’s exploration team using 3D software and once this is completed, it will be utilised to design a new RC drilling program, as well as provide further information for management to consider geophysical surveys at Coppermine.
Additional RC drilling is scheduled to commence in late 2023 or early 2024 at the most prospective projects in the Central Goldfields, including Victor Bore, Great Northern, Barlow’s Gully, Craig’s Rest and Chicago.

APPENDIX 2, JORC Code, 2012 Edition - Table 1
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. • 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. |
Infinity RC Drilling 2023 •A total of 37 x reverse circulation (RC) drill holes were completed by Infinity Mining Ltd in the Central Goldfields of WA, in late January to early March 2023. •RC Drilling was completed at five different projects (Victor Bore, Great Northern, Barlow’s Gully, Camel, Coppermine). •Holes were drilled to depths ranging from 78 to 132 m, for a total advance of 3851 m drilled. •Holes were drilled at various azimuths, with dips largely at -60 degrees. •Reverse circulation drilling was used to obtain 1 m samples from the rig-mounted cyclone, from which a 2-3 kg representative split sample was collected into calico sample bags via a cone splitter. •A total of 2286 RC drill chip samples were collected during the program, including one (1) metre RC samples within logged zones of interest, plus four (4) metre composite samples outside those logged zones of interest. •Samples were dispatched to Jinning Laboratory in Perth for analysis. •The calico bag samples were then dried, crushed and pulverised. •Gold was analysed by 50g charge for fire assay with AAS finish. •The samples were also assayed for multi-element analysis by ICP- OES, for a 33-element suite (results pending). |
|
| 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). |
•RC drilling was conducted by iDrilling Australia, Drilling Contractors using an Hydco 350 RC rig using a 5.5-inch face sampling hammer bit. •PVC casing was used at each hole to protect the collar. •Drilling methods and equipment were to best industry standard. |
|
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. |
•Recovery can be monitored by observing the consistency of drill chip amounts collected for each 1 m sample. |
15
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| • 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. |
•No significant loss of recovery was observed in any 1 m intervals during the program. •Typical recoveries for this RC program are estimated to be in excess of 80%. •Samples were largely dry, with only a few samples being moist. •No significant groundwater was encountered that would impact recovery. |
|
| 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. |
•Geological logs were completed for all drill holes by an experienced geologist. •The lithology, weathering, oxidation, colour, grainsize, texture, alteration, veining, structure and mineralisation were recorded in digital spreadsheets at the time of drilling. •Logs are largely qualitative in nature using company logging codes. •Logging of sulphide mineralisation and quartz veining was quantitative. •All intervals drilled were logged. |
| 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. |
•RC drilling was used to obtain 1 m split samples, from the rig- mounted cyclone, from which a 2-3 kg split sample was collected into pre-numbered calico bags using a cone splitter. •A total of 2286 RC drill chip samples were collected during the program, including one (1) metre RC samples within logged zones of interest containing quartz veining and mineralisation/alteration, plus four (4) metre composite samples outside those logged zones of interest. •No drilled intervals were left unsampled. •Back-up samples for every 1 m drill interval were also collected and securely stored. •The 4 m composite samples were collected using a manual sample spear and sent to the laboratory for analysis. If any assays from the 4 m composite samples contain anomalous assay results, these will be re-assayed at 1 m intervals. •All samples were transported to Jinning Laboratory in Perth for analysis. •Samples were dried, crushed and pulverized to nominal 85% passing 75microns, priorto assaying. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Geology | • Deposit type, geological setting and style of mineralisation. | • The Central Goldfields tenements are located in the Leonora District of the Central Goldfields. The projects lie within greenstone belts associated with several NW-trending faults such as the Ursus Fault Zone. The tenements in the same area as a number of significant gold deposits such as King of the Hills and Kailis. • The greenstones are also intruded by younger Archean granites. • The projects are prospective for orogenic Archaean shear-hosted gold systems and Volcanogenic Massive Sulphide (VMS) base- metal deposits. |
| Drill hole Information |

•See Table - Appendix 1 |
| 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. |
•All gold intercepts quoted within the Table in the body of the report are weighted averages Gold (g/t), using a cut-off of 0.1 g/t Au. •Where gold repeats were recorded, the first sample was used to calculate the weighted average grade. •No assays below the cut-off (internal “waste”) were included in the intercepts. •Additional multi-element assays are pending. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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 gold-bearing intervals quoted in the report are close to being perpendicular but are not true widths. |
| 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. |
•All maps have been inserted within the announcement. See diagrams in body of 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 to avoid misleading reporting of _Exploration Results. _ |
•It is uncertain that further exploration work will lead to the reporting of a Mineral Resources, in accordance with the requirements of the JORC 2012 Code. |
| 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. _ |
•There is no other exploration data that is considered to be material to the results reported herein. |
| 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. |
•All gold and multi-element assays have been received. •A more detailed 3D interpretation will be completed by the Infinity geological team over the coming months. •Further exploration work in the Central Goldfields is planned, including RC drilling. •Deeper RC drilling is recommended at several projects including Victor Bore and Great Northern. •Refer to the main body of the announcement. |
