Central Goldfields Projects
The Craig’s Rest Project (P37/8468, E37/1442) is part of Infinity’s Central Goldfields portfolio which includes eight projects in the Leonora Gold District of Western Australia. The Central Goldfields Projects are highly prospective for Archaean shear-hosted gold systems.
The Central Goldfields tenements all lie in areas of Archaean greenstone, associated with major NNWtrending fault zones such as the Ursus Fault. A number of significant gold deposits, such as King of the Hills (held by Red 5 Limited – ASX: RED) and Kailis (held by Northern Star Resources Limited – ASX: NST) lie in close proximity to these tenements (see Figure 1 ).

Geology
The Craig’s Rest Project is located 60 km NNW of Leonora, hosted by Archean granites (see Figure 1 ). The tenement area includes a number of outcrops and areas of thick soil and alluvial cover. Several WNW trending shear zones cut across the tenement area. A detailed geology map is included as Figure 2 .
Previous Mining
Small-scale gold mining occurred at Craig’s Rest over 100 years ago, in the late 1800s. The WA Department of Mines mining database (WABMINES & MINEDEX) reports a total of 85 mine shafts, adits and open pits located at three main prospects (Garden Well, Katalina, Craig Prospects). Mine records indicate that the gold mineralisation was hosted in steeply dipping quartz reefs and stringer zones, within shear zones hosted in granite. Workings at Garden Well extend over a strike length of approximately 500 m. These old gold mine workings are located along interpreted WNW-trending shear zones, as shown on Figure 2 .
Rock Chip Sampling
A rock chip sampling program was carried out by Infinity at the Craig’s Rest Project to confirm the presence of gold in the areas around the old gold workings. A total of 47 rock chip samples were collected in the areas around the Garden Well, Katalina and Craig Prospects. Six (6) of the samples returned anomalous gold assays over 1 g/t Au with a maximum of 37.64 g/t Au.
These anomalous gold samples confirm the high-grade tenor of the gold mineralisation at Craig’s Rest. A map showing the location of the anomalous gold assay results is included as Figure 3 . Gold assay results for all samples collected by Infinity are included in Table 1 . Sampling details are outlined in the JORC Table 1 in Appendix 1 .

Structural Targets
A number of WNW-trending and EW-trending structural target zones have been identified at Craig’s Rest for further exploration work. Regional WA government magnetic images have been used to identify linear magnetic lows which are interpreted as altered / magnetic-depleted structural (fault) zones. The Garden Well, Katalina and Craig’s prospects lie along these linear magnetic-depleted fault zones but have not been explored along strike. These structural target zones with be explored further, for shearhosted gold mineralisation.
Forward Plans
Aircore drilling and soil auger drilling programs are planned over the coming months over the structural target zones, which occur along strike from the main gold prospects. Aircore and auger drilling is required to penetrate through the thick zones of soil and alluvial cover. A map showing the highest priority structural target zones is included as Figure 4 .

APPENDIX 1 - 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. |
•Rock chip samples between 1 to 3 kg were collected in 2022 by a qualified geologist on site. •A total of 47 rock chip samples were collected from Craigs Rest. •All sample information, including lithological descriptions and GPS coordinates were recorded during the sampling process. •Individual samples were bagged in calico bags and sent to Jinning Testing and Inspection Laboratory in Kalgoorlie, WA, for gold and multi-element analysis. |
| Drilling techniques |
