Cosmopolitan Gold Mine Drilling Results
-
Final assays from the recent 12 hole drill programme at the Cosmopolitan Gold Mine at the Kookynie Gold Project[1 ] have been returned, with best intercepts including:
-
COSRC0026 - 1 metre @ 5.4 g/t from 193 metres and:
- 1 metre @ 3.9 g/t from 202 metres.
-
COSRC0027 - 1 metre @ 4.4 g/t from 183 metres and:
- 1 metre @ 7.7 g/t from 208 metres.
-
COSRC0029 - 2 metres @ 2.1 g/t from 165 metres.
-
COSRC0030 - 6 metres @ 1.4 g/t from 182 metres.
-
These are the first 12 holes that have been drilled by the Company in and around the historic Cosmopolitan mine which produced 360,000 ounces at 15 g/t Au.
-
The Company is highly encouraged by the initial scout drilling conducted and about the potential for high grade extensions to the old mine; with more work programmes now planned to follow.
-
All assays from the recent drilling programme across the wider Project have been returned and the Company will commence its next programme shortly with a focus on McTavish and the 2km of untested strike between McTavish and Leipold, where recent results included[2] :
-
McTRC0049 - 5 metres @ 25.9 g/t from 28 metres
-
McTRC0064 - 6 metres @ 20.6 g/t from 19 metres
-
McTRC0044 - 3 metres @ 19.1 g/t from 88 metres
Metalicity Limited (ASX: MCT) (“MCT” or “Company”) is pleased to announce the gold results from the historic Cosmopolitan Gold Mine at the Kookynie Gold Project[1] in the Eastern Goldfields, Western Australia, approximately 60 kilometres south southwest of Leonora.

Cautionary Statement Relating to the Cosmopolitan Production Data
The Production details for the Cosmopolitan Mine are referenced from publicly available data sources. The source and date of the production data for the Cosmopolitan Gold Mine has been reported in the Geological Survey of Western Australia records showing the development of the Cosmopolitan Gold Mine in 1905. DMIRS digital records include open file Annual Reports and data pertaining to the exploration and development efforts of previous operators. Two documents with WAMEX reference numbers A069774 and A067918 are of particular interest. The previous operator in the early 2000’s, Point Exploration Ltd, digitised these historical maps, including the channel sampling. The historical production data have not been reported in accordance with the JORC Code 2012. A Competent Person has not done sufficient work to disclose the historical production data in accordance with the JORC Code 2012. It is possible that following further evaluation and/or exploration work that the confidence in the prior reported production data may be reduced when reported under the JORC Code 2012 Nothing has come to the attention of the operator that causes it to question the accuracy or reliability of the historical production data; An assessment of the additional exploration or evaluation work that is required to report the data in accordance with JORC Code 2012 will be undertaken as part of the Company’s development plan.

Commenting on the drilling results, Metalicity CEO, Justin Barton said:
“These were the first 12 holes drilled by Metalicity at Cosmopolitan and we are highly encouraged by the initial results and more work is now planned to test potential extensions to the historic high-grade mineralisation that was mined here.”
“The results were not what we were expecting given the detection of visible gold during drilling. Following a detailed investigation of the drilling programme and extensively re-testing assays, we have been able to identify that a significant amount of water was encountered in the hole announced with visible gold, that has led to potentially only 20% recovery through this interval. Although incredibly frustrating, this does provide us with significant encouragement that the drilling results at Cosmopolitan potentially understate the gold recovered recently and historically, given the higher grades we have consistently encountered at all the other nearby prospects, namely McTavish, Champion and Leipold.”
Summary of Cosmopolitan Gold Mine Assay Results
Seven of the 12 holes drilled at the Cosmopolitan Gold Mine have delivered significant intercepts, further highlighting the potential of this prospect. Whilst values returned are not at historical grades it is highly encouraging to intersect the structure that hosted the historical workings and confirm that this mineralisation continues. As articulated in this announcement, incredibly high variability in re-assaying has been encountered with the current results. Nevertheless, the Cosmopolitan Gold Mine was once one of the largest gold mines in Western Australia during its time.

Table 1 – Cosmopolitan Gold Mine Anomalous Drill Hole Intercepts.
Note: Duplicates and CRM analysis was not used in the calculation of the significant intercepts. A hole listed with “no significant anomalism” means that no sample run returned a value to trigger reporting.
The intercepts above were calculated based on a sample returning an assay value of greater than 1 g/t Au over an interval greater than 2 metres, but not including any more than 1 metre of internal material that graded less than 1 g/t Au. Intervals were based on geology and no top cut off was applied.

Visible Gold Anomaly
During the drilling of COSRC0022 the site geologist reported that he had observed a visible gold fleck in an RC chip in the chip tray in the 227 to 228 metre sampling interval, as shown in Photograph 1 below. This led to an expectation that the interval would deliver an assay result which could be anything from 1 to 100 + g/t Au, but in all events at least over 10 g/t Au.
==> picture [360 x 251] intentionally omitted <==
Photograph 1 – Visible gold from interval 227-228 metres in COSRC0022 at the Cosmopolitan Gold Mine.
Please refer to ASX Announcement “First Hole Intersects Visible Gold at the Cosmopolitan Prospect, 100m North of Historic Cosmopolitan Gold Mine” dated 4 February 2021. Please note the wrong hole ID was displayed in the previous announcement.
The location for COSRC0022 was designed to test what was hoped to be the possible location of the southern extent of the Cumberland zone of mineralisation at depth. The targeting was inferred from up dip stopes and an estimate of dip / strike of the mineralised horizon, as well as the up-dip sampling information.
This interval in question is in the expected target zone, which appears to be a typical (shear hosted lode gold) quartz vein of variable thickness (~0.2 to +2 metre) in a shear / vein structure system, which can host good high gold grades based on the reported results of the historic hand sampling in the workings and from historic production figures.
However, when the interval was assayed, the Intertek Laboratory reported a fire assay and screen fire assay result of no gold, and separately, the SGS Laboratory reported a screen fire assay reported of 0.02 g/t gold.
An investigation was launched, and several further assays carried out on residual pulps, with these additional results only confirming the original Intertek and SGS findings.
It was noted; however, that during the drilling of the hole and particularly the interval in question, a significant amount of water was encountered in the hole and sample recovery had been compromised. The field geologist stated that sample recovery was an issue during the drilling when the structure was encountered. The samples had been dry, with good recovery up to that point.
An estimate has been made that there may have been only 20% recovery through this interval with fines being

preferentially lost.
Following further analysis, we have concluded that as the distribution of gold in this interval is highly variable, it is unlikely to have been adequately representatively sampled due to the poor recovery and loss of material caused by excessive uncontrolled water inflows. The target zone is likely to have contained a thin (probably sub 20 to 30 cm) quartz vein with variable amounts of coarse gold.
More detailed discussion and analysis of this can be found in Appendix Two attached.
Notwithstanding the above, future drilling at Cosmopolitan will attempt to RC drill to close proximity of the target mineralised horizon and then diamond core through the structure so that sample losses due to sudden onset of large amounts of water are minimised and sample representivity is maintained as best as possible
Kookynie Drilling Results to Date
With the completion of all outstanding assays for Cosmopolitan, Champion, Leipold and McTavish Prospects over the past few weeks, all outstanding assays are now published.
The Company is now in the process of finalising plans for its next exploration efforts. The initial focus will be at McTavish, along with the 2km of untested strike between McTavish and Leipold, where the Company is becoming increasingly confident these prospects could link up into one bigger system of multiple similar high grades lodes seen at both prospects. Recent results from McTavish were outstanding and included*:
-
McTRC0049 - 5 metres @ 25.9 g/t from 28 metres
-
McTRC0064 - 6 metres @ 20.6 g/t from 19 metres
-
McTRC0044 - 3 metres @ 19.1 g/t from 88 metres

mineralisation bodes exceptionally well for this future initial Mineral Resource Estimate at Champion, McTavish and Leipold. With these results received the Company is making significant headway into completing these initial Resource Estimates.
Of significance, is that all three of these prospects remain open in one or more directions and these results clearly defined areas to target in the next drilling programme.
Kookynie Gold Project
Kookynie is located 60 kilometres south south-east from Leonora in Western Australia and is host to nine significant prospects: Champion, McTavish, Leipold, Altona, Mulga Plum, Wandin, Diamantina, Cosmopolitan and Cumberland. Diamantina, Cosmopolitan and Cumberland are known collectively as the DCC Trend, please refer to Figure 2 above.

Appendix One – JORC Code, 2012 Edition – Table 1
Section 1: Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary ● Reverse circulation (RC) sampling was conducted by the offsiders on the drill rig and checked at the end of each rod (6 metres) to ensure that the sample ID’s matched the interval that was intended to be represented by that sample ID. No issues were seen or noted by the Competent person during the entire drilling campaign. These samples are kept onsite in a secure location available for further analysis if required. ● All RC samples were sieved and washed to ensure samples were taken from the appropriate intervals. The presence of quartz veining +- sulphide presence +- alteration was used to determine if a zone was interpreted to be mineralised. If the sample was deemed to be potentially mineralised, the samples were submitted for screen fire assay. If no mineralisation was observed, the sample was submitted for check using fire assay. ● All samples were submitted for analysis, no compositing took place. ● The quality of the sampling is industry standard and was completed with the utmost care to ensure that the material being sampled, can be traced back to the interval taken from the drill hole for both RC and diamond core. However, for specific intervals, sample recovery in RC is discussed. ● OREAS standards of 60 gram charges of OREAS 22F (Au grade range of <1ppb Au – this is a blank), OREAS 251 (Au grade range of 0.498ppm Au to |

| 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. |

● RC drilling used a bit size of 5 ¼ inch. |
| Drill sample recovery | ● Method of recording and assessing core and chip sample recoveries and results assessed. ● Measures taken to maximise sample recovery and ensure representative nature of the samples. ● Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
● RC drilling sample recovery was excellent except in the structures discussed above and in Appendix Two. ● There appears to be a relationship displayed between recovery and grade nor loss/gain of fine/course material. |

● If core, whether cut or sawn and whether quarter, half or all core taken. ● If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. ● For all sample types, the nature, quality and appropriateness of the sample preparation technique. ● Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. ● Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. ● Whether sample sizes are appropriate to the grain size of the material being sampled. |
● RC samples were cone split from the rig. Then subsequent resampling as defined in the tables above was conducted. ● Most RC samples were dry. However, sample recover and wet samples were an issue during the intersection of the mineralised lodes at the Cosmopolitan Gold Mine. ● Duplicates or a CRM standard were inserted every 20 samples. ● The Competent Person is of the opinion the sampling method is appropriate. |

| Quality of assay data and laboratory tests |
● The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. ● For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. ● Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
● Fire assay and screen fire assay methods have been selected for RC samples. The methodology employed in these analytical procedures are industry standard with appropriate checks and balances throughout their own processes. ● The analytical method employed is appropriate for the style of mineralisation and target commodity present. However, selected entire intercepts with a returned weighted average assay above 5 g/t Au will be selected and analysed using the screen fire method to provide a statistical comparison between the two analytical methods in high grade zones. This is to ensure the high-grade nature (nugget effect) is defined and articulated. However, as discussed in Appendix Two, issues were identified and explained. ● Nogeophysical tools, |

● Umpire analysis has been presented with requisite statistical interrogation. Please refer to Appendix Two for a detailed account. ● No twinned holes have been completed. However, drill holes have been collared near previously drilled holes but on different orientations. ● Data was collected on to standardised templates in the field and data entered at night. Cross checks were performed verifying field data. ● No adjustment to the available assay data has been made. |
| Location of data points | ● Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. ● Specification of the grid system used. ● Quality and adequacy of topographic control. |
● Drill hole collars will be surveyed using a DGPS. ● The RC holes were downhole surveyed using a “Champ Gyro multi-shot down hole survey camera”. ● GDA94 Zone 51S was used, collars will be picked up by a qualified surveyor using a DGPS (Trimble S7). ● The surveyed collar coordinates appear to be sufficient, however, better definition is required of the topography to allow for a JORC 2012 compliant estimation. ● Appendix Two contains collar coordinates as drilled: |

The historical work completed requires further field verification via re-down hole surveying (if possible) of drill holes beyond 60 metres depth – it appears below this depth; hole deviation becomes a factor in establishing the location of mineralisation in 3D. Furthermore, collar pickups require verification. All laboratory certificates for the assays on file are collated, only recommendation is possibly more duplicate information in mineralised zones.

The project area is in the Keith-Kilkenny Tectonic Zone within the northnorthwest trending Archean-aged Malcolm greenstone belt. The KeithKilkenny Tectonic Zone is a triangular shaped area hosting a succession of Archean mafic-ultramafic igneous and metasedimentary rocks. Regional magnetic data indicates the Kookynie region is bounded to the west by the northtrending Mt George Shear, the Keith-Kilkenny Shear Zone to the east and the Mulliberry Granitoid Complex to the south.

There are several styles of gold mineralisation identified in the Kookynie region. The largest system discovered to date is the high-grade mineralisation mined at the Admiral/Butterfly area, Desdemona area and Niagara area. The gold mineralisation is associated with pyritic quartz veins hosted within north to

Appendix Two – Detailed Assay Result Discussion
The drilling at Cosmopolitan has provided results that are difficult to explain given the visible gold seen in the selected interval (Photograph 1). This interval then assayed below detection in the initial Intertek laboratory fire assay and screen fire assay testing, and 0.02 g/t Au for the initial SGS screen fire assay.
This interval is located in the expected target zone, which appears to be a typical (shear hosted lode gold) quartz vein of variable thickness (~0.2 to +2 metre) in a shear / vein structure system, which can host good high gold grades based on the results of the hand sampling in the workings and from historic production figures. Clearly the historic underground production would have focussed on the broader mineralisation zones, meaning potential shallow (relatively) residual zones that are the target of this drill hole are likely to be fairly narrow. The representivity of the hand samples is impossible to determine, as the sampling methodology is unknown. If, as is very likely, they were taken by chip sampling the sample results will be biased. Despite the assumption that that sampling is biased, it was still used to guide exploration drill planning efforts along with the underground development information. The location of COSRC0022 tests what was hoped to be the possible location of the southern extent of the Cumberland zone of mineralisation at depth. The targeting was inferred from up dip stopes and an estimate of dip / strike of the mineralised horizon, as well as the up-dip sampling information.
The site geologist reported that he had discovered a visible gold fleck in an RC chip in the chip tray in the 227 to 228 metre sampling interval and sent the photograph as illustrated in Photograph One. This led to an expectation that the interval would deliver an assay result in keeping with visible gold having been seen which could be anything from 1 to 100 + g/t Au, and most likely at least over 10 g/t Au.
In keeping with the expectation that results can be extremely variable due to the coarse gold commonly encountered at the Kookynie Project prospects, the assay strategy was designed to negate this problem. Each sample interval deemed reasonably prospective based on locational and visual cues had three primary samples sent for assay, being 50 gram fire assay to Intertek, 1 kg screen fire assay to Intertek and 500 gram screen fire assay to SGS. The expectation being that with three separate samples of different sizes and methods of the intervals we would be able to show and attempt to quantify variability in sample results.
Once the initial Intertek results were returned with below detection result for both fire and screen fire assay; however, we saw we had a real problem, as with the visible gold at least some detectable level of gold was expected. The Intertek sample residues were retrieved and sent for “umpire” (umpire – taking the same sample that was analysed at one laboratory and checking the result against another laboratories performance using the same analytical method) analysis at SGS by 50 gram fire assay. The two samples then returned values of 0.02 g/t Au, which is at least a detection but not near expected values. In the meantime, the original screen fire analysis sample sent to SGS returned a value of 0.02 g/t Au, which was still not in the expected range.
However, sample recovery had been compromised due to unexpected significant water flow whilst the hole was being drilled. The field geologist stated that sample recovery was an issue during the drilling when the structure was hit. There was a very significant water flow through the sample return (samples had been dry with good recovery) up to that point, and it is estimated that the Company had probably recovered 5kg of sample, from what should have been approx. 25kg dry sample. This implies a 20% recovery with fines preferentially lost. Drilling in the southern area encountered significant water issues with the other holes displaying moderate to good recoveries as the drillers adapted the drill technique to keep the samples dry.

In order to further test the interval a riffle splitter was obtained to prevent bias in subsequent sample slits and the remainder of the sample material from the interval was split into eight ~500 g samples and submitted for fire assay analysis at SGS. The results then returned a range of values from below detection up to a maximum of 1.5 g/t Au, with one other sample at 1.2 g/t Au, as shown in the table below:

Cosmopolitan Gold Mine Anomalous Drill Hole Intercept resampling information.
A statistical analysis showed what was intuitive and already known i.e. the sample (and the mineralisation at Kookynie generally) is highly variable or nuggety consisting of largely coarse gold rather than evenly distributed disseminated gold. Coarse gold is highly unevenly distributed at the close range, small scale, as encountered in a drill hole sample and as such analysis results can be expected to be highly variable as shown in the table above, and visually demonstrated in the bar chart below. Note that the below detection values were converted to ½ detection (i.e. 0.005 g/t Au) for the purposes of the analysis.

All statistical measures such as coefficient of variation show high variability of the results for the 13 samples from the single metre. The screen fire assay analysis with the larger sample size being analysed does not appear to have performed any better than the smaller fire assay in this case.
In conclusion this interval is unlikely to have been adequately representatively sampled due to the poor recovery and loss of material caused by excessive uncontrolled water. The target zone is likely to have contained a thin (probably sub 20 to 30 cm) quartz vein with variable amounts of coarse gold. The two samples that have returned above 1 g/t Au demonstrate the variability and the existence of gold in the overall interval. I would probably also recommend that the mean value of 0.22 g/t Au be used as the database value for this interval as it is probably closer to representative of the interval than any one individual sample.
Future drilling at the Cosmopolitan Gold Mine should attempt to RC drill to close proximity of the target and then diamond core through the structure so that sample losses due to sudden onset of large amounts of water are minimised and sample representivity is maintained as best as possible.
