EXECUTIVE CHAIRMAN COMMENTS
“This confirmation in hole 19 of the copper, gold and silver to the south outside the previously drilled main area of the Mt Cannindah breccia zone is fantastic to see, and again a testament to the team and the professional approach to the exploration we have been completing. The current IP survey showing encouraging signs of further scale opportunity is exactly what we wanted to see, as well as very positive metallurgical test work. This project is building and building with each approach we adopt. The plan from here is to continue this exploration and show the true scale potential of the project area. We are doing this at a time where the major miners around the world are hunting for copper and the inventories are at historic lows, the timing could not be better to be getting these results. I look forward to updating shareholders with further assays from drilling, along with the IP survey and Metallurgical testing once these are completed.”

LAB RESULTS COPPER MINERALISED BRECCIA CAE HOLE 19 AT MT CANNINDAH
Cannindah Resources Limited (“Cannindah”, “CAE”) has now received laboratory results which confirm earlier observations of a significant zone of copper, gold and silver bearing hydrothermal breccia intersected in CAE hole # 19 at Mt Cannindah – see ASX report 19/5/2023. These are the latest developments from the drilling program currently underway at Mt Cannindah copper gold silver project south of Gladstone near Monto in central Queensland (Figs 1 to 3). Core is being processed and assay lab results are awaited from the bottom of hole # 19. With holes # 20-22, recently being completed, core processing and assaying is underway. Hole # 23 is currently being drilled in the southern section of the Mt Cannindah Breccia. A major IP survey is also underway across the width of the CAE Cannindah tenements, meaning logistical considerations have to be taken into account to ensure that there is little to no disruption to the smooth running of both the drilling and geophysical operations.
CAE Hole # 19’s targeted purpose and preliminary results were reported previously in ASX Announcement 19/5/2023. Some of the key points are repeated here in order to provide context for the lab results. Hole 23CAEDD019 was collared to the south of the main drilled section of the Mt Cannindah mine area, targeting the extent and continuity of copper-gold - silver breccia and intrusive hosted mineralization intersected in sub-parallel CAE holes # 13 & 18. Fig 4 shows the location and key drill intercepts in these holes. CAE Hole # 19 drills between CAE Holes # 13 & 18, with the section containing the trace of CAE hole #13 some 50m to the north west, and CAE hole # 18 some 75m to south east of the trace of CAE hole # 19. Previously reported results from these holes are show in Fig 4. See: CAE ASX Announcement 23 March 2023.
Hole # 13 (CAE ASX Announcement 30 September2022) reported the following:
-
Drilled two extensive zones (approx. 100m downhole widths of 1% CuEq*) within the primary zone of infill hydrothermal breccia.
-
(1) 36m to 140m : 104m @ 1.0% CuEq,(0.63% Cu, 0.41g/t Au, 14.1g/t Ag).
-
(2) 229m to 337m : 108m @ 1.01% CuEq,(0.57% Cu, 0.58g/t Au, 9.8g/t Ag.
-
CAE Hole #13 also intersected some significant intervals of gold :
-
(1) 0m to 24m , 24m@ 2.11 g/t Au, 10.9 g/t Ag, 0.52 % Cu a high grade oxidised gold zone from surface within gossanous hydrothermal infill breccia
-
(2) 314m to 329m : 15m @ 2.78g/t Au, which include 4m @ 6.50 g/t Au 9.8g/t Ag. The core of the system here is a prominent semi-massive sulphide infill zone, containing high grade gold with grades up to 22.98 g/t Au, 60.0 g/t Ag , with high Zn, Pb, elevated Bi.
Hole # 18 drills in a south south westerly direction (magnetic direction at collar of 206 degrees). CAE reported results in CAE ASX Announcements 23[rd] March,2023, and 3[rd] April, 2023.

Hole # 18 was collared in flinty hornfels, which is cut by an extensive vein fracture network as the Hydrothermal Infill Breccia is approached downhole, crossing the contact at 138.6m. Copper and gold bearing sulphidic breccia occurs below 138m, cut by some bleached altered, argillized porphyry and thin post mineral andesite dykes. Results reported from the top of CAE Hole # 18 (ASX Announcement, 23March 2023) are highly significant with:
a high copper breccia zone of 21m @ 0.98%CuEq, 0.75% Cu,0.22 g/t Au,11.0g/t Ag occurring 138m – 159m.
and two high grade gold zones :
18m @ 6.34 g/t Au, 0.18%Cu, 17.2g/t Ag (4.18CuEq) (244m-262m) up to 23.93 g/t Au, 61g/t Ag . 20m @ 5.5 g/t Au, 0.81%Cu, 23g/t Ag (4.34CuEq) (355m-375m) up to 23.93 g/t Au, 61g/t Ag, with 1m of 96.16 g/t Au, 1.46% Cu, 123.2 g/t Ag.
The intervals in CAE hole # 18 aggregate to :
275m @ 1.03% CuEq, 0.29%Cu, 1.11 g/t Au ,7.9 g/t Ag,4.33 % S (103m-378m) which includes a more sulphidic , higher gold zone of :
104m @ 1.22% CuEq, 0.27%Cu, 1.46 g/t Au ,7.5 g/t Ag, (274m-378m)
Hole # 19 is located in the southern section of Mt Cannindah Mine area (see Fig 4) and drills in a south westerly direction (magnetic direction at collar of 216 degrees) with an inclination at the drill collar of -55 degrees.
Fig 5 is a cross section showing simplified geology over the trace of Hole # 19 traverses. Table 1 is a summary geology log. Similar geology to Hole # 18, is noted: collaring in flinty hornfels, which is cut by an extensive vein fracture network, which grades into an hornfels dominated shatter breccia at 131m. At 156m, there is a faulted contact with hydrothermal sulphidic infill breccia, which is clast supported, dominated by angular blocks and fragments of hornfels, some porphyry clasts, with prominent infill of calcite, quartz , pyrite and chalcopyrite. (see Fig 4)
Chlorite is dominant in some of the uphole sections of the breccia, sericite alteration becomes more prominent down hole and dominates from 175m or so. The infill breccia is cut by some bleached altered, argillized porphyry and thin late and post mineral andesite/trachy-andesite dykes, which are often argillized.
Sulphide content is generally high throughout the hydrothermal infill breccia, although there is a variation in chalcopyrite content. Sulphide content can build up to semi-massive levels either side of dykes.

ADDITIONAL DEVELOPMENTS MT CANNINDAH PROJECT
IP Survey
Commencing in June,2023, a major IP survey is underway at Mt Cannindah. The initial proposed survey is illustrated in Fig 16. The professional contractor is Geophysical Resources & Services (GRS) based in Brisbane, utilising their MIMDAS system. Key components of the proposals are a pole-dipole regional survey covering the Mining Leases at Mt Cannindah with extensions into CAE’s surrounding EPMs. Line spacing is 400m, with a 200m dipole spacing. A detailed 3D IP survey covering the main breccia and extensions is also planned. This is proposed to be a 3D pole -dipole survey with a line spacing of 100m, and dipole spacing of 100m.

On the 7270600N line, a prominent chargeability anomaly is coincident with the breccia at Mt Cannindah, reflecting large sulphide accumulations seen in CAE’s recent drilling. A similar size anomaly is also present approximately 1km to the east, where only sparse relatively shallow drilling has occurred. This anomaly is modelled as dipping off to the east.
On the 7269800N line prominent chargeability anomalies are also present. The western anomaly is split with one section possibly the extension of the Mt Cannindah mineralisation. This has to be evaluated. Again, there is a large-scale modelled chargeability anomaly 1km or so to the east which is in the vicinity of known porphyry style mineralisation at the United Allies prospect. This anomaly is also modelled to dip to the east.
These preliminary IP results are very encouraging. However, it needs to be noted that chargeability anomalies can have a range of sources, not always related to sulphide mineralisation. The IP survey to date has successfully located significant targets for evaluation and drill testing. The MIMDAS IP and magneto-telluric system has been designed to obtain electrical responses from deep targets. The preliminary modelling suggests that the Mt Cannindah anomalies are modelling to depths untested to date by earlier drilling.
Metallurgy
Metallurgical test-work is also currently being conducted by Core Metallurgical Consultants based in Brisbane. Preliminary results received to date have been very encouraging with excellent floatation attributes and recoveries obtained from rougher floatation tests. From a grinding perspective, the ore shows hardness indexes typical of hard-rock deposits. More testwork is underway and full results will be reported on completion.

Formula for Copper Equivalent calculations
Copper equivalent has been used to report the wider copper bearing intercepts that carry Au and Ag credits, with copper being dominant e.g. have confidence that existing metallurgical processes would recover copper, gold and silver from Mt Cannindah. We have confidence that the Mt Cannindah ores are amenable to metallurgical treatments that result in equal recoveries. This confidence is reinforced by some preliminary metallurgical test work by previous holders, geological observations and our geochemical work which established a high correlation between Cu, Au, Ag.
The full equation for Copper Equivalent is:
CuEq/% = (Cu/% * 92.50 * CuRecovery + Au/ppm * 56.26 * AuRecovery + Ag/ppm * 0.74 * AgRecovery)/(92.5* CuRecovery)
When recoveries are equal this reduces to the simplified version: CuEq/% = (Cu/% * 92.50 + Au/ppm * 56.26 + Ag/ppm * 0.74)/ 92.5
We have applied a 30 day average prices in USD for Q4,2021, for Cu, Au , Ag , specifically copper @ USD$9250/tonne, gold @ USD$1750/oz and silver @ USD$23/oz. This equates to USD$92.50 per 1 wt %Cu in ore, USD$56.26 per 1 ppm gold in ore, USD$0.74 per 1 ppm silver in ore . We have conservatively used equal recoveries of 80% for copper, 80% for gold, 80% for Ag and applied to the CuEq calculation. CAE are conducting Metallurgical test work to quantify these recoveries.

| Follow up results from CAE holes # 13, # | ||
| 17 # 18 show that the east – west trending | ||
| andesite dykes encountered in many holes | ||
| are thin (mostly less than 5m true | ||

| grade veins and sulphidic zones have also | ||
| been shown to be east-west and the | ||
| southerly drill direction of CAE Hole #19 is | ||
| entirely appropriate to test these |
||
| structures. . | ||
| Historical and CAE drill results show that | ||
| there are several orientations of |
||
| mineralized zones , breccia bodies and pre | ||
| and post mineral dykes . The most | ||
| common orientations are broadly east | ||
| west, and north south . In this regard, | ||
| geological consultants Terra Search have | ||
| planned drill holes of various orientations | ||
| to target the known range of orientations | ||
| observed and measured in the mineralised | ||
| structures and breccia bodies. |
If the relationship between drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
The Infill breccia is massive textured , recent interpretation suggests the clasts may have an imbrication or preferred orientation, that is gently to moderately dipping to the east or south east. The overall orientation of the Mt Cannindah breccia sheet is steeply dipping to the west , although the bounding structures are uncertain. CAE Hole # 19 was drilled in a southerly direction, at right angles to the mostly east west holes at Mt Cannindah. One of the key aims of Hole # 19 was to determine the true thickness of mineralised east west structures. A further objective was to help determine grade continuity along the north east to south west trend within the breccia zone . No sampling bias is evident in the logging, or the presentation of results on drill cross and long sections. Steep structures are evident and with steep inclined holes these are cut at oblique angles. The breccia zone at Mt Cannindah is of sufficient width and depth that drillhole 23CAEDD019 provides valuable unbiased information concerning grade continuity of the breccia body.

Commentary Observations of core reported here in Hole 19 show an alignment of breccia clasts that is broadly at a high angle to the drill hole, indicating the hole orientation is appropriate for the broadly east west oriented structures and geological units. The complete geometry of the breccia body is unknown at this stage. Similarly, vein structures have several orientations and only in certain instances is it evident that vein orientations have introduced a sampling bias. These are well documented with oriented core. Historically, most holes at Mt Cannindah have been drilled from west to east . These can be severely hampered when encountering the similar parallel direction of east west post mineral andesite dykes and other structures. This situation was evident in CAE hole # 15 which drilled down an east west dyke for a lot of its length. This relationship did demonstrate that following the historical drill pattern at Mt Cannindah does not necessarily lead to optimum results. Analysis of these geological relationships has led geological consultants Terra Search to design drill directions both 180 degrees and 90 degrees contrary to the historical direction. This drill pattern has produced outstanding results , leading to drill intersections of considerable grade and length. From preliminary investigation of the grade model It is anticipated that there is little overall evidence of any sampling bias in the CAE drilling at Mt Cannindah.

We have conservatively used equal recoveries of 80% for copper, 80% for gold , 80% for Ag and applied to the CuEq calculation.
Relationship between mineralisation widths and intercept lengths
The 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).
22CAEDD019 reported here is an angled hole, inclined 55 degrees to the south west (magnetic azimuth 216 degrees at the drill collar). The hole is collared on fractured oxidised hornfels.
As the breccia geometry is still to be established, the final attitude and thickness of the mineralisation is unknown at this stage.
. The Mt Cannindah Infill breccia is massive textured , recent interpretation suggests the clasts may have an imbrication or preferred orientation, that is relatively flat dipping to the east or south east.
The overall orientation of the Mt Cannindah breccia sheet is steeply dipping to the west , although the bounding structures are uncertain. The south westerly drill direction of hole #18 was considered important to determine whether mineralised breccia extended in that direction..
Previous resource estimations at Mt Cannindah model the breccia body as elongated NNE-SSW and at least 100m plus thick in an east west direction. Previous estimations indicate a potentially depth extension to 350m plus.. The breccia body geometry, as modelled at surface has the long axis oriented NNESSW. In this context, hole 22CAEDD019 drills to the south west of the mineralised envelope previously recognized at Mt Cannindah, . raking across the strike of the overall body
CAE Hole # 19 is drilling to the south south west and parallels CAE hole # 13 & 18 which intersected several breccia and dyke like bodies at high angles .Observations of core reported here in Hole 19 show an alignment of breccia clasts that is broadly at a high angle to the drill hole, indicating the hole orientation is appropriate for the broadly east west oriented structures and geological units.. In this regard, the orientation of hole # 19 was entirely appropriate for the geometry and trends of the targeted bodies and structures.
