-
➢ Diamond drilling is progressing well, and the 3D IP survey is expected to be completed in the coming week
~~➢~~
Great Boulder Resources (“ Great Boulder ” or the “ Company ”) (ASX: GBR ) is pleased to advise all remaining assays have been received for the Phase 5 reverse circulation (RC) and Phase 5 air-core (AC) drilling programs completed in late 2021, at the Side Well Gold Project (“ Side Well ”) near Meekatharra in Western Australia. The Company has also received assays for the first 38 holes of a 148-hole AC program drilled earlier this year at Mulga Bill and Jones Well.
The RC results have continued to define high-grade mineralisation in the central area of Mulga Bill, with intersections of up to 1m @ 97.97g/t Au. Recent Phase 5 AC results have infilled the Loaded Dog area of Mulga Bill with intersections such as 3m @ 6.69g/t Au in 21SWAC147, and have also extended known mineralisation at the nearby Ironbark discovery to 500m.
Initial results have also been received from the recent 148-hole AC drill program completed in early March 2022. This program included 25 holes exploring further south on the Mulga Bill corridor, and 123 holes testing geochemical anomalies at Jones Well. Significantly, results from the first 19 holes at Jones Well have identified anomalous mineralisation on the first target, with results pending for 106 holes in that area and four follow-up holes at the southern end of Mulga Bill.

Great Boulder’s Managing Director, Andrew Paterson commented:
“We’re very glad to have received results from the balance of last year’s programs. This removes a significant bottleneck in our exploration process, as the new lab are already sending results for holes sampled in February.”
“The balance of the RC assays at Mulga Bill have provided important information on mineralised orientations in the high-grade zones, and we are starting to see evidence of interacting sub-vertical and flat-dipping structures. This observation may be interpreted as an orogenic overprint on an earlier epithermal system which we inferred from the lithogeochemical studies with Dr Scott Halley.”
“Infill AC drilling in the Loaded Dog area of Mulga Bill returned some significant grades up to 3m @ 6.69g/t Au, which is very high for AC drilling in this environment. We recently drilled more AC holes around the high-grade hit in 21SWAC119, which ended with 1m @ 23.78g/t Au, and we will be aiming to continue to define that zone along strike.”
“I am also excited to see that Ironbark now has 500m of mineralised footprint, and we may also have made our first gold discovery up at Jones Well.”
“The Side Well project is progressing simultaneously on several fronts, which is fantastic to see. We’re making good progress towards our 100,000m drilling target this year which will be a major step towards our goal of reporting a mineral resource estimate on Mulga Bill. It’s really going to be a big year for Great Boulder.”

Ironbark
The Ironbark prospect, located to the south-east of Mulga Bill, was discovered during 2021. Initially identified by auger sampling, first-pass AC drilling identified anomalous gold including 8m @ 2.39g/t Au in hole 21SWAC101, reported on 28 September 2021.
Results from AC drilling completed at Ironbark in October appear to have closed off mineralisation to the north, however the 500m-long north-northeast-trending mineralised zone remains open to the south and results such as 3m @ 1.21g/t Au in hole 21SWAC158 provide further encouragement. The next stage of exploration at Ironbark will include drilling a number of RC holes to test mineralisation in fresh rock below these AC hits.

FIGURE 4: AC DRILL COVERAGE TO DATE AT IRONBARK. THE BACKGROUND IMAGE IS TOTAL MAGNETIC INTENSITY (TMI).
Jones Well
The Jones Well area encompasses the northern third of Side Well. There are several areas at Jones Well where cross-cutting structures and small igneous intrusions have disrupted the greenstone stratigraphy, providing ideal dilational conditions for gold mineralisation. While records exist for a small number of RAB holes drilled at Jones Well during the mid-1990’s the area remains largely unexplored.
A first-pass, broad-spaced soil sampling program and subsequent infill soil sampling during 2021 identified several discrete, low-tenor geochemical anomalies. A first-pass AC program was completed during February 2022 to test some of these anomalies. Assays for 19 of 123 AC holes drilled at Jones Well have already been received, which is a significant improvement on sample assay turnaround.
Significantly, these results include 6m @ 0.38g/t Au from 60m to end of hole (EOH) in 22SWAC054 including 2m @ 0.59g/t from 64m to EOH, and 4m @ 0.66g/t Au from 40m in 21SWAC064. These results are very positive in the context of AC drilling, and end-of-hole mineralisation is particularly encouraging as it implies potential for primary gold mineralisation in the fresh rock. Follow-up drilling will test whether these two results are located on a northeast-striking mineralised zone.
The remaining assays for the Jones Well program are expected to be received in the coming weeks.

Next Steps
Diamond drilling is progressing well at Mulga Bill, with the program expected to be completed towards the end of March. RC drilling is expected to recommence as soon as the diamond program is complete.
The 3D IP survey is expected to be completed in the coming week, with results and analysis anticipated as soon as the data has been processed. This survey is designed to define a 3- dimensional model of chargeable zones at Mulga Bill caused by sulphides in the rock mass. The 3D model will be used to plan additional drill targets testing gold mineralisation associated with these sulphide-rich zones, both at depth and along strike.

APPENDIX 1 - JORC CODE, 2012 EDITION TABLE 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | Commentary |
|---|---|
| Sampling techniques | RC samples were collected into calico bags over 1m intervals using a cyclone splitter. The residual bulk samples are placed in lines of piles on the ground. 2 cone splits are taken off the rig splitter for RC drilling. Visually prospective zones were sampled over 1m intervals and sent for analysis while the rest of the hole was composited over 4m intervals by taking a spear sample from each 1m bag. |
| Drilling techniques | RC Drilling was undertaken by Challenge Drilling. AC drilling was undertaken by Prospect Drilling. Industry standard drilling methods and equipment were used. |
| Drill sample recovery | Sample recovery data is noted in geological comments as part of the logging process. Sample condition has been logged for every geological interval as part of the logging process. Significant ground water was encountered in drilling which resulted in numerous wet samples. No quantitative twinned drilling analysis has been undertaken. |
| Logging | Geological logging of drilling followed established company procedures. Qualitative logging of samples includes lithology, mineralogy, alteration, veining and weathering. Abundant geological comments supplement logged intervals. |
| Sub-sampling techniques and sample preparation |
1m cyclone splits and 4m speared composite samples were taken in the field. Samples from the 2021 drilling program were prepared and analysed at Genalysis Assay Laboratories Perth, while those drilled during 2022 were analysed by ALS in Perth. Samples were pulverized so that each samples had a nominal 85% passing 75 microns. Au analysis was undertaken using FA50/OE involving 50g lead collection fire assay and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) finish. |
| Quality of assay data and laboratory tests |
All samples were assayed by industry standard techniques. |
| Verification of sampling and assaying |
The standard GBR protocol was followed for insertion of standards and blanks with a blank and standard inserted per 40 samples. No QAQC problems were identified in the results. No twinned drilling has been undertaken. The gravity data was checked and verified independently by a consulting geophysicist. |
| Data spacing and distribution |
The spacing and location of the majority of drilling in the projects is, by the nature of early exploration, variable. The spacing and location of data is currently only being considered for exploration purposes. |
| Orientation of data in relation to geological structure |
Drilling is dominantly perpendicular to regional geological trends where interpreted and practical. True width and orientation of intersected mineralisation is currently unknown or not clear. The spacing and location of the data is currently only being considered for exploration purposes. |
| Sample security | GBR personnel were responsible for delivery of samples from the drill site to the courier companies dispatch center in Meekatharra. Samples were transported by Toll Intermodal from Meekatharra to the laboratory in Perth. |
| Audits or reviews | Data review and interpretation by independent consultants. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | Commentary |
|---|---|
| Mineral tenement and | Side Well tenement E51/1905 is a 48-block exploration license covering an area of 131.8km2 |
| land tenure status | immediately east and northeast of Meekatharra in the Murchison province. The tenement is a 75:25 |
| joint venture between Great Boulder and Zebina Minerals PtyLtd. | |
| Exploration done by | Tenement E51/1905 has a protracted exploration history but is relatively unexplored compared to |
| other parties | other regions surrounding Meekathara. |
| Geology | The Side Well tenement group covers a portion of the Meekatharra-Wydgee Greenstone Belt north |
| of Meekatharra, WA. The north-northeasterly trending Archaean Meekatharra-Wydgee Greenstone | |
| Belt, comprises a succession of metamorphosed mafic to ultramafic and felsic and sedimentary rocks | |
| belonging to the Luke Creek and Mount Farmer Groups. | |
| Over the northern extensions of the belt, sediments belonging to the Proterozoic Yerrida Basin | |
| unconformably overlie Archaean granite-greenstone terrain. Structurally, the belt takes the form of | |
| a syncline known as the Polelle syncline. Younger Archaean granitoids have intrusive contacts with | |
| the greenstone succession and have intersected several zones particularly in the Side Well area. | |
| Within the Side Well tenement group, a largely concealed portion of the north-north-easterly | |
| trending Greenstone Belt is defined, on the basis of drilling and airborne magnetic data, to underlie | |
| the area. The greenstone succession is interpreted to be tightly folded into a south plunging syncline | |
| and is cut by easterly trending Proterozoic dolerite dykes. | |
| There is little to no rock exposure at the Side Well prospect. This area is covered by alluvium and | |
| lacustrine clays, commonly up to 60 metres thick. | |
| Drill hole Information | A list of the drill hole coordinates, orientations and intersections reported in this announcement are |
| provided as an appended table. | |
| Data aggregation | Results were reported using cut-off levels relevant to the sample type. For composited samples |
| methods | significant intercepts were reported for grades greater than 0.1g/t Au with a maximum dilution of |
| 4m. For single metre splits, significant intercepts were reported for grades greater than 0.8g/t Au | |
| with a maximum dilution of 2m. | |
| A weighted average calculation was used to allow for bottom of hole composites that were less than | |
| the standard 4m and when intervals contain composited samples plus 1m split samples. | |
| No metal equivalents are used. | |
| Relationship between | The orientation of structures and mineralisation is not known with certainty, but majority of the |
| mineralisation widths | drilling drilling was conducted using appropriate perpendicular orientations for interpreted |
| and intercept lengths | mineralisation. Diamond drilling has confirmed a mineralised intrusive body at Side Well has a near |
| vertical dip and trends broadly north-south. Due to the wide spacing of drill lines exact orientation is | |
| not clear. | |
| Diagrams | Refer to figures in announcement. |
| Balanced reporting | It is not practical to report all historical exploration results from the Side Well project. Selected |
| historical intercepts have been re-reported by GBR to highlight the prospectivity of the region. Full | |
| drillhole details can be found in publicly available historical annual reports. | |
| Other substantive | Subsequent to Doray Minerals Limited exiting the project in 2015, private companies have held the |
| exploration data | ground with no significant work being undertaken. |
| Further work | Further work is discussed in the document. |
