HIGH GRADE GOLD RESULTS CONTINUE AT MULGA BILL

HIGHLIGHTS

  • High grade gold results returned from ongoing drilling at the Mulga Bill prospect including:

  • 13m @ 25.50g/t Au from 96m, including 4m @ 76.9g/t from 100m, and 5m @ 8.65g/t from 182m in hole 22MBRC061 (HGV area)

  • 10m @ 28.74g/t from 96m, including 4m @ 29.40g/t from 96m and 1m @ 121.00g/t from 101m, in hole 22MBRC067 (Central Zone)

  • 14m @ 5.22g/t from 92m, including 4m @ 7.56g/t from 96m and 2m @ 20.47g/t from 102m, in hole 22MBRC069 (Central Zone)

  • Drillholes 22MBRC067 and 22MBRC069 contain some of the highest grade intersections outside the high-grade vein (HGV) area at Mulga Bill. These intersections sit within the central area of Mulga Bill, associated with primary Cu-Au-Ag mineralisation (Central Zone) and have been submitted for multi element analysis

  • Drill testing of the new high-grade zone recently discovered east of the HGV area (GBR announcement dated 29/09/22) has confirmed the potential of this area including:

  • 22m @ 1.27g/t Au from 228m, including 4m @ 4.33g/t from 246m, in hole 22MBRC076

  • 4m @ 6.33g/t Au from 204m, including 2m @ 12.1g/t Au from 204m, and 8m @ 2.49g/t from 252m including 1m @ 17.05g/t from 259m in hole 22MBRC082

  • AC drilling has highlighted strong gold anomalism along strike in the Loaded Dog and Flagpole areas for follow up RC drilling. Pathfinder anomalism along strike from Ironbark highlights that structural corridor.

  • RC Drilling remains ongoing with Phase 4 RC drilling results at Ironbark pending

Great Boulder Resources (“ Great Boulder ” or the “ Company ”) (ASX: GBR ) is pleased to announce and update of drilling results at the Side Well Gold Project (“ Side Well ”) near Meekatharra in Western Australia.

Great Boulder’s Managing Director, Andrew Paterson commented:

“These results demonstrate exciting upside across a number of prospects. Firstly, we have some extremely high-grade results in the central area of Mulga Bill which has seen less drilling than the HGV area. These hits highlight the potential for additional high-grade zones to the south.”

“Secondly we have extended the HGV area further north and opened up the potential that it may continue north of the cross-cutting Proterozoic dyke. This area remains relatively untested by RC drilling so there is a lot of scope for extensions in that direction.”

“Thirdly the intersections on our new eastern high-grade lode discovery from a small number of test holes provide confidence in our geological model and targeting process.”

“Lastly, and significantly is the ongoing identification of new targets coming from our AC drilling. With new areas to test at Flagpole, Loaded Dog and Ironbark South we have a very busy program ahead of us.”

RC Drilling

Results have been received from a series of holes drilled at Mulga Bill during August and September. Drilling was conducted at both the High Grade Vein (HGV) area in the north and the Primary Zone in the centre of the Mulga Bill prospect. Significant results include:

  • 13m @ 25.50g/t from 96m , including 4m @ 76.90g/t from 100m, and 5m @ 8.65g/t from 182m including 1m @ 35.40g/t from 183m in 22MBRC061 (HGV area)

  • 10m @ 28.74g/t from 96m , including 4m @ 29.4g/t from 96m and 1m @ 121.00g/t from 101m in 22MBRC067 (Central Zone)

  • 14m @ 5.22g/t from 92m , including 4m @ 7.56g/t from 96m and 2m @ 20.47g/t from 102m in 22MBRC069 (Central Zone)

FIGURE 3: SECTION 7060400N SHOWING NEW HIGH GRADE INTERSECTION FROM THE CENTRAL ZONE AT MULGA BILL.

The drillholes returned from the Central Zone represent some of the highest grade intersections at Mulga Bill outside of the HGV area. These intersections occur proximal to the fresh rock boundary and some supergene enrichment of gold may be present, however fresh quartz veining is associated with the intervals suggesting a primary source. This source may be a shallow west-dipping high grade vein similar to those encountered further to the north at Mulga Bill. These holes were drilled

FIGURE 4: SECTION 7060300N SHOWING NEW HIGH GRADE INTERSECTION FROM THE CENTRAL ZONE AT MULGA BILL.

Drilling has confirmed the orientation and continuity of the new lode discovered in the previous phase of drilling (see ASX announcement dated 29/09/22) east of the HGV area. This lode appears to be a similar shallow dipping orientation to the main high grade vein hosting significant gold to the west (Figure 2). This new mineralised structure remains completely untested along strike and at depth, and will be a focus for further exploration.

The main high grade vein structure has been extended 30m to the north by drillhole 22MBRC075 and mineralisation is now trending into an area that remains untested by RC drilling. A postmineralisation dyke cuts through this area however drilling will need to be undertaken to the north of this dyke to test for the continuation of mineralisation.

AC Drilling

Results from the fourth phase of regional aircore drilling have been received. Holes were drilled at Ironbark and Loaded Dog, with 2 free holes drilled by the contractor at Flagpole to test the rig configuration. Significant results include:

  • 8m @ 1.02g/t from 48m in hole 22SWAC264 (Loaded Dog)

  • 20m @ 1.07g/t from 16m in 22SWAC265 (Loaded Dog)

  • 4m @ 4.24g/t from 108m in 22SWAC316 (Flagpole)

Gold anomalism at Loaded dog now defines a 900m plus zone within the regolith profile (Figure 5) with gold occurring at a shallow depth in some areas. Further RC drilling is needed at this prospect to test the extent and orientation of primary mineralised structures.

Drilling at Flagpole has added to the geological confidence that high grade gold is hosted in shallow west-dipping vein sets similar to those seen at Mulga Bill.

Drilling to the west, east and south of Ironbark did not return any significant gold mineralisation however pathfinder anomalism highlights the continuation of the structure thought to be controlling the gold at Ironbark.

Next Steps

RC drilling is ongoing, with a further fourth phase of RC drilling at Ironbark now complete. At Ironbark South, drilling operations are now paused while the latest results are evaluated, and reconnaissance work is completed.

This announcement has been approved by the Great Boulder Board.

Appendix 1 - JORC Code, 2012 Edition Table 1 (Side Well Project) 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 scoop sample from each 1m bag.
AC samples were placed in piles on the ground with 4m composite samples taken using a scoop.
Drilling techniques Industry standard drilling methods and equipment were utilised.
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. Water was
encountered during drilling resulting in minor wet and moist samples with the majority being dry.
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 were
prepared and analysed at ALS Laboratories Perth for the RC drilling and Intertek Laboratories for
the AC drilling. Samples were pulverized so that each samples had a nominal 85% passing 75
microns. Au analysis was undertaken using Au-AA26 involving 50g lead collection fire assay and
Atomic Adsorption Spectrometry (AAS) finish. For AC drilling, Au analysis was undertaken using a
50g lead collection fire assay with 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 25 for RC drilling and 40 samples for AC drilling. No QAQC problems were
identified in the results. No twinned drilling has been undertaken.
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 Ipec from Meekatharra to the
laboratories in Perth.

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 0.5g/t Au
with a maximum dilution of 3m.
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. Stratigraphy appears to be steeply dipping to the west however mineralisation may
have a different orientation.
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.
