Hammer’s Managing Director, Daniel Thomas said:
“Our recent drilling program in Mount Isa continues to deliver substantial copper-gold intersections. This program scouted seven different prospects, with significant mineralisation observed at six of the target zones. These results continue to highlight the prospective nature of the Mount Isa region and the opportunity for our assets to contribute to the future copper supply from this region.
The prospective corridor running from Neptune through Trafalgar, Lakeview and up to our JORC compliant copper and gold resources at Elaine and Jubilee is proving to be fertile for further copper and gold mineralisation.
With sustained higher copper prices and a growing copper inventory, Hammer remains well placed to continue its journey from exploration to base metal development company. With results still pending from our most recent program in Mount Isa, upcoming drilling programs in Mount Isa and at our Bronzewing South gold project, Hammer is set for a busy and productive end to 2021.”

| ^ - Mt Isa East Joint Venture |
Four holes were initially drilled at Lakeview (for 300m) and this drilling was sufficiently encouraging to follow up with a further 9 holes (for 1080m) to determine whether the prospect had mineralisation continuity sufficient to progress to a resource drill-out. To date, assays for the first three holes of this additional drilling have been received.
Three holes for 734m were drilled at Overlander North. Two of these holes were testing the southern margin of the Overlander IOCG target and the remaining hole tested the northern extents of a large tonnage rhyolite breccia target.
At Kalman West, three holes (for 487m) were drilled with a single 300m hole testing an MT and VTEM target and the two remaining holes testing the recent discovery of visible gold. (See ASX announcement dated 26 July 2021).
At Serendipity, two holes (for 244m) were designed to test a quartzite unit with an anomalous Cu and Au soil response close to the Pilgrim Fault zone.
Lakeview Update
The initial three-hole (300m) program was successful in delineating mineralisation and a second nine-hole (1080m) program was completed to further investigate mineralisation at depth (refer to ASX announcement dated 22 June 2021). The aim of this follow-up drilling was to determine whether a Cu-Au resource could be defined at Lakeview to add to Hammer’s existing mineral resource inventory.
After considerable delays in receiving results from the assay laboratory, the results for 3 of the 9-hole followup program have been received. Significant intercepts from these three holes include:
-
18m at 1.7% Cu and 0.49g/t Au from 61m in HMLVRC005, including;
o5m at 4.17% Cu and 1.04g/t Au from 61m; -
13m at 0.59% Cu and 0.15g/t Au from 66m in HMLVRC007, including; and
-
1m at 1.42% Cu and 0.46g/t Au from 77m; and
-
3m at 1.73% Cu and 1.42g/t Au from 147m in HMLVRC007.

Preliminary assessment of the drilling results indicates that the higher-grade zones of mineralisation plunge steeply, and with increasing depth the Cu to Au ratio remains consistent. Two of the holes drilled during this program were subject to a downhole electromagnetic survey to determine whether any off-hole conductors were present, and the data generated from this program is currently being modelled by Hammers’ geophysical consultants – Newexco.
In combination with this follow-up drilling, geological mapping and rock chip sampling was conducted to define extensional targets. The mapping indicated that vein mineralogy is consistent with the peripheral expression of an IOCG system and there are two main follow up targets within the general Lakeview area.
Recent field mapping and rock chip sampling undertaken highlighted the relationship between mineralised structures and the margin of zones of magnetite alteration. Maximum individual grades of 18.9% Cu, 23.6g/t Au and 0.17% Co were obtained by this sampling. New target zones at Orion (North) and Ajax (South) have been defined. Both Orion and Ajax have not previously been drilled. Orion, is located on the margin of a magnetite alteration zone in a similar position to Jubilee, Black Rock and the Neptune group of prospects. Carbonate dominant veins are present on the margin of the quartzite over a strike length of 300m and gossanous quartzite has been mapped within the alteration zone.
Based on previous drilling results, downhole electromagnetics, mapping and sampling, Hammer has designed a follow-up drilling program to test this highly prospective area. In addition, an extensive soil sampling program is underway with the aim of improving the geochemical coverage of the Trafalgar to Jubilee trend within the Lakeview region.

Overlander Update
Three holes for 734 meters were drilled at the Overlander North Prospect. Two of these holes were designed to test the southern margin of the Overlander IOCG alteration zone. Both holes intersected favourable alteration, however failed to intersect significant mineralisation.
The third hole, OVRC035 was designed to test a rhyolitic crackle breccia on the eastern margin of Overlander North. The hole intersected 78m @ 0.26% Cu from 75m. Notably the Cu intersection is accompanied by anomalous Zn levels with an individual maximum grade of 0.21% Zn.
The rhyolitic breccia outcrops sporadically over a 1.6km strike length and is tested by only four holes (including OVRC035). The unit can be up to 100m in true thickness. The other three holes have similar thick copper intersections including:
Page 8 of 26
-
71 metres at 0.31% Cu from 61 metres within a broader envelope of 104 metres at 0.25% Cu in OVRC024 ;
-
104m at 0.25% Cu from 30m in OVRC032; and
-
115m at 0.31% Cu from 128m in K-111 .
The rhyolitic crackle breccia at Overlander is considered to have the potential to host a large tonnage Cu-Co resource. A review of the previous IP survey completed at Overlander is underway with a view to optimizing future drill targeting of this large target.
OVRC033 and OVRC034 were drilled to test the southern margin of the Overlander IOCG deposit in addition to intersecting the Overlander shear structural position (which hosts the Overlander North Cu resource). Both holes failed to intersect significant mineralisation.

Kalman West
Three holes for 487m were drilled at Kalman West targeting both a MT/VTEM anomaly and a zone of surface quartz veining with visible gold.
HKWRC009 (299m TD) was drilled to test the shallow expression of an MT anomaly beneath the Kalman West Shear Zone. This hole intersected a copper bearing hanging wall zone on the western margin of the Kalman West Shear Zone followed by anomalous Pb-Zn-Ag mineralisation with induvial assays of up to 1.86% Pb, 0.95% Zn and 18.1g/t Ag hosted by graphitic metasediments. Anomalous Au was intersected in structures interpreted to be along strike of several significant gold intersections encountered 200m to the north. (See ASX announcement dated 26 July 2021).
Significantly the anomalous Pb-Zn-Ag mineralisation occurring at Kalman West was associated with anomalous Sb and Cd. This element association displays hallmarks of large sediment-hosted, Mt Isa style, mineralised systems highlighting the prospectivity of the area.
Significant intercepts from HMKWRC009 include:
-
37m at 0.14% Cu from 8m (including 1m @ 1.86% Pb and 0.31% Zn);
-
10m at 0.19% Cu from 84m (including 1m @ 0.42% Pb and 0.65% Zn); and
-
7m at 0.19g/t Au from 120m.
Two further holes were designed to intersect a zone of visible gold (refer to ASX release dated 26 July 2021). HMKWRC010 and HMKWRC011 intersected zones of significant gold and base metals anomalism including:
-
2m at 0.15g/t Au from 24m in HMKWRC010;
-
6m at 0.27g/t Au from 68m including 1m at 0.95g/t Au from 70m in HMKWRC011;
Page 11 of 26
As with HMKWRC009, both HMKWRC010 and HMKWRC011 intersected anomalous zones of Ag, Pb and Zn with individual maximum responses of 44.5g/t Ag, 0.67% Pb and 0.66% Zn respectively.
HMKWRC009 will be subject to a downhole electromagnetic survey late in 2021. Select gold-bearing samples will be subject to screen fire assays as coarse gold associations may not be readily apparent in conventional analyses of reverse circulation drill chips.

Neptune IOCG Target Area
Lady Rose Drilling
Results from the initial 3-hole program (728m) confirmed the nature of copper-gold mineralisation at Lady Rose and the overall potential of the Neptune region (refer to ASX announcement dated 26 July 2021) for large IOCG deposits. Significant results from this first exploration program were:
-
100m at 0.48% Cu and 0.18g/t Au from 173m (HMLRRC002) including
-
3m at 2.23% Cu and 0.2g/t Au from 185m;
-
3m at 3.09% Cu and 1.4g/t Au from 198m; and
-
5m at 2.21% Cu and 0.37g/t Au from 234m.
-
66m at 0.32% Cu and 0.07g/t Au from 33m (HMLRRC003) including
-
2m at 1.92% Cu and 0.42g/t Au from 33m
Holes HMLRRC002 and HMLRRC003 have been subject to a downhole Electromagnetic Survey and the data from this survey is currently being processed by Hammer Geophysical consultants – Newexco.
Neptune Rock Chip Sampling and Geological Mapping
Geological mapping, three-dimensional gravity modelling, geological modelling, follow-up rock chip sampling and downhole electromagnetic surveying have been conducted over the Neptune region since drilling has been completed. This work has highlighted two follow-on targets within the area for the next drilling phase. Maximum individual rock chip analyses of 27% Cu, 9.95g/t Au and 0.1% Co were obtained from this sampling.
Drill planning is underway to test the Morning Star and Lady Kate trends later this year. These targets are located on the same geological contact but exhibit different styles of alteration.
The Morning Star trend consists of a series of shafts and pits observable over approximately 500m. This trend occurs on the northern margin of the Argylla Formation. Drilling by Placer in the 1980’s and Paradigm Metals in the 2000’s indicated that mineralization is present at depth however this drilling did not test the entire width of the mineralized system.
Page 14 of 26
The second new target is Lady Kate. This target consists of a 600m long zone of magnetite alteration within the Ballara Quartzite. Soil sampling undertaken by Paradigm Metals outlined a strong Copper anomaly. No historic drilling has tested this target.

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. |
Drill chip samples were taken at dominantly 1m intervals. When multiple metre intervals were sampled, a riffle split of each metre interval was conducted with the split portions then being combined to produce a composite sample. Where mineralisation was anticipated or encountered, the sample length was reduced to 1m with lab submission of the 1m samples. The average sample length and weight for the assays reported herein is 1.2m and 3.51kg respectively. All samples submitted for assay underwent fine crush with 1kg riffled off for pulverising to 75 microns. Samples were submitted to SGS in Townsville for: • Fire Assay with AAS finish for gold. • 4 acid digest followed by ICP-MS and ICP-OES for a 49 element suite. Portable XRF analysis was conducted in the field on each 1m interval. Re-analyses will be conducted as required to investigate element repeatability. Reconnaissance rock chip sampling is reported in this release. The nature of sampling is termed grab sampling. Samples are collected across the strike of the zone of mineralisation, but sampling is not via the continuous chip method. This style ofsampling enables generalgrade |

| and metal content to be established however it is not as representative as continuous chip sampling, costean sampling or drilling to establish grade across a structure. Samples tabulated in this release have been taken from both mineralised and unmineralised material. This is a common practice to determine background element concentrations in an area. |

| Drilling techniques |
Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Holes were drilled by DDH1 drilling using a Sandvik DE840 (UDR1200) drilling rig. The holes were drilled by the reverse circulation method. The reverse circulation technique which uses a face sampling hammer to reduce contamination. |
| 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/gainof fine/coarse material. |
Sample recoveries were generally in excess of 80%. Recoveries are typically low in the first 5m of each hole. In holes where recovery or significant sampling bias was observed, the hole was terminated. No sample recovery bias has been noted. |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the _relevant intersections logged. _ |
All drilling was geologically logged by Hammer Metals Limited Geologists. Quantitative portable XRF analyses were conducted on metre intervals on site. All metres were drilled were analysed by the lab methods listed above. |
| Sub- sampling techniques and sample preparation |
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. |
Samples consist of RC drill chips. Samples from the hole were collected by a three-way splitter with A and B duplicates taken for every sample. Samples were taken at dominantly one metre intervals however when 2 or 4 metre compositeswere created, sampleswere |

composited by riffle splitting material from each one metre sample bag. Where evidence of mineralisation was encountered or anticipated, the sample length was reduced to 1m. Sample collection methodology and sample size is considered appropriate to the target- style and drill method, and appropriate laboratory analytical methods were employed. Standard reference samples and blanks were each inserted into the laboratory submissions at a rate of 1 per 25 samples. Rock chip sample weight was between 3 and 5kg per site.No standard samples were submitted with the rock chip samples. |
|
| 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. |
Each metre drilled was subject to site portable XRF analysis. All samples were analysed for gold by flame AAS using a 30gm charge. Each sample was also analysed by 4-acid multielement ICP OES and MS. Standard reference samples and blanks were inserted at 20 sample intervals. SGS also maintained a comprehensive QAQC regime, including check samples, duplicates, standard reference samples, blanks and calibration standards. Rock Chip Samples were analysed by ALS for a range of elements by ICP (OES) after an aqua regia digest. Gold was analysed via flame AAS. The analytical method is appropriate for reconnaissance rock chip sampling. |

|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been _applied. _ |
The drill density is not sufficient to establish grade continuity. The average grade has been utilised where multiple repeat analyses have been conducted on a single sample. |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the 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. |
Drill holes were oriented as close to perpendicular as possible to the orientation of the targets based on interpretation of previous exploration, however true width estimations will not be conducted until there are two drill hole intersections present on each section. With Rock Chip samples, sampling was conducted at right angles to the strike of the host structure. |
| Sample security |
The measures taken to ensure sample security. |
Pre-numbered bags were used, and samples were transported to SGS in Townsville by a commercial carrier. Samples were packed within sealed bulka bags. With Rock Chip samples, Pre-numbered bags were used, and samples were transported to ALS laboratory in Mt Isa by company personnel. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
The dataset associated with this reported exploration has been subject to data import validation. All assay data has been reviewed by two company personnel. No externalauditshave beenconducted. |

Overlander Prospect Overlander is composed of three major elements: A shear zone hosted style of mineralisation which comprises the Overlander North and South JORC resources; A IOCG alteration zone abutting the shear on its western side; and an eastern breccia hosted mineralisation which is has the potential to host a large tonnage deposit. Kalman West Prospect Kalman West is located 500m to the west of the Kalman Au-Cu-Mo-Re deposit. Mineralisation is hosted within a graphitic shear zone and consists of a western Cu domain and an eastern Lead-Zinc domain. Gold bearing Quartz veins occur in both domains. Serendipity Prospect Serendipity is located approximately 10km to the south of Kalman on the Pilgrim Fault Zone. Neptune group of prospects Mineralisation in this region is hosted by the Ballara Quartzite in close proximity to the Corella Formation contact. Exploration by Hammer Metals and other parties has identified widespread mineralisation along this contact in the northern portion of the Mary Kathleen Fold Belt. The mineralisation style is consistent with possible proterozoic shear hosted mineralisation or Iron Oxide copper gold (IOCG) association. Lakeview Prospect The Lakeview Prospect is located on the Trafalgar to Jubilee trend approximately halfway betweenthe two prospects. |

| Mineralisation along this trend is associated with magnetic highs and is located close to the boundary between the Ballara Quartzite and the Corella Formation. Copper is present as Chalcopyrite. There is a Cu-Au association at Lakeview and this is also seen at the Jubilee Cu-Au deposit located along this trend to the north. |

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain _why this is the case. _ |
See the attached tables. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly _stated. _ |
Intercepts are quoted at a 0.2% Cu and/or 0.1g/t Au cut-off with included intercepts highlighting zones of increased copper and/or gold and cobalt grade. |
| Relationship between mineralisation widths and intercept lengths |
These 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 (eg ‘down hole length, true width not known’). |
The relationship between intersected and true widths for both prospects drilled is not known with certainty until further drilling has been conducted. Surface rock chip sampling cannot be utilised to determine the geometry of any possible mineralisation at depth. The sampling methodology can only be used to determine a range of possible grades and is commonly used at a reconnaissance stage. |

| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced avoiding misleading reporting of Exploration Results. |
Intercepts are quoted at a 0.2% Cu and/or 0.1g/t Au cut-off with included intercepts highlighting zones of increased copper and/or gold and cobalt grade. Portions of a drillhole that are not quoted in the intercept table contain grades less that the quoted cut-off. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating _substances. _ |
