Results
The recent Infinity RC drilling program was successful in verifying the subsurface gold mineralisation, as reported by Melita Mining NL in Melita’s Annual Report to August 1988 (WAMEX Report A25349). Assays from the Infinity RC program returned multiple gold intercepts over 1 g/t Au, with individual assays up to 10.95 g/t Au (1 m sample).
Significant gold intercepts from the Infinity RC program are reported below in Table 3 , which were calculated using both 0.2 and 0.5 g/t Au cut-off grades.
4 | P a g e
Significant intercepts from the Melita Mining ML RC drilling program (1987-88) are also included below in Table 4 for comparison. The maximum gold assay from the Melita program was 24.1 g/t Au, from 12-13 m (EOH) in hole GN06. All gold intercepts quoted within Tables 3 and 4 are weighted averages of the gold assays from 1 m RC drilling samples, using a cut-off grade of 0.2 or 0.5 g/t Au. Two different cut-off grades were applied to better define the extent of the gold mineralisation. Infinity has confidence in the Melita drilling data, as the historical results compare moderately well with Infinity’s drilling results, and therefore Infinity has reported the Melita drilling results under the JORC (2012) Code and included all details of this historical program, plus the Infinity drilling program, in the attached JORC Table 1.

Interpretation
The Infinity RC drilling program has confirmed the continuity of gold mineralisation below the historical workings at Great Northern. The significant gold intercepts from the Infinity program compare moderately well with the historical Melita program (see Tables 3 and 4 ). The gold mineralisation at Great Northern is hosted in quartz-veins within felsic to intermediate schists. The zones of quartz veining dip steeply to the SW,

Next Steps
Given these excellent first-stage results, Infinity will now undertake more detailed 3D modelling of the geology and gold mineralisation. The 3D modelling will also help Infinity to design a new drilling program, to test for extensions of the gold mineralisation at depth and along strike. The drilling to date, has only tested mineralisation to shallow depths (maximum 70 m), therefore deeper drilling is well justified.

Joe Groot, CEO of Infinity Mining commented:
“The Company is very pleased to have intersected significant gold mineralisation on its maiden drilling program, shortly after its ASX listing in December 2021. The drilling results have verified historical drilling results and identified several zones of gold mineralisation below the historical workings at Great Northern, which are open at depth. Further drilling by Infinity is planned, to explore for extensions.
Over the next few months, our geological team will conduct more exploration around the Central Goldfields group of tenements in the Leonora District. A range of surveys are planned ahead of more drilling campaigns. In addition, the team will visit the Pilbara tenements in mid-April, looking at ways to fast-track the planned Lithium exploration programs. The Pilbara is now a high-priority area, given the high prospectivity of our tenements for Lithium and the global interest in Lithium.
Infinity is spending a large proportion of the funds raised in December 2021 in the ground, with multiple exploration programs kicking off in the next few months. We have a big program planned for 2022, ensuring a steady stream of market updates from here on.”

(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary | |
|---|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 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. |

Section 2 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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 tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• Great Northern Gold Prospect is located within tenement P37/8310 held by Infinity Mining Limited. • The tenement covers an area of 1.34 sq km. • The POW for drilling was approved. • The Infinity tenement (P37/8310) is in good standing. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Previous exploration was conducted by Melita Mining NL in 1987 which included RC drilling of 11 holes up to a maximum of 80 m depth. North Limited conducted limited aircore drillingin the Great Northern region in the 1990s. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The Great Northern Gold Prospect is located in the Leonora district of WA. • Shear-hosted gold mineralisation in the Leonora region lies within a number of Archean greenstone belts. • A line of old workings occur at the Great Northern prospect has been observed over a strike length of approximately 80 m. • Mineralisation is associated with quartz-veins which outcrop at surface and dip steeply to the northeast. The vein mineralisation is hosted within felsic to intermediate schists. • Steeply-NE dipping quartz-vein mineralisation was intersected in the RC drill holes. |

| 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: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole 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 explain why this is the case. |
• Drill collar files for Infinity and Melita RC drilling programs are included in the body of this report. |
|
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Infinity RC Drilling Program 2022 • All samples were collected at 1 m intervals. • All gold intercepts quoted within the Table in the body of the report are weighted averages Gold (g/t), using a cut-off of 0.2 or 0.5 g/t Au. Two different cut-off grades were applied to better define the extents of the gold mineralisation. • Where gold repeats were recorded, the average of all the samples was used. • No assays below the cut-off (internal “waste”) were included in the intercepts. Melita RC Drilling Program 1987 • Reverse circulation drilling was used to obtain 1 m split samples. The 1 m samples were composited into 2 m intervals for assaying • All gold intercepts quoted within the Table in the body of the report are weighted averages Gold (g/t), using a cut-off of 0.2 or 0.5 g/t Au. Two different cut-off grades were applied to better define the extents of the gold mineralisation. • Where gold repeats were recorded, the average of all the samples was used. • No assays below the cut-off(internal “waste”)were included in the intercepts. |
|
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• The drill holes were designed to drill roughly perpendicular to the steep NE dipping zones of known gold mineralisation at surface. • Drill holes were oriented to return the best intersections of the mineralisation, and drilled in a perpendicular manner. • The mineralised drill intersections are reported as down hole intervals and were not converted to true widths. • The mineralised intercepts 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. |
• 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. • All significant gold intercepts using a 0.2 and 0.5 g/t Au are reported in the Table within this report. • It is uncertain that further exploration work at Great Northern 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. • The results of historical RC drilling (11 drill holes) by Melita in 1987 at Great Northern was reviewed by the company. This historical drilling program was originallyreportedprior to the JORC Code(2012). |
| Further work • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. • Further RC drilling is planned at Great Northern to test for extensions of the gold mineralisation. |
