Q3 FY2021 Quarterly Activities Report

Group Safety, Environment and Community

There were two lost time injuries (LTI) and one reportable environmental incident across the Group during the quarter.

The two LTIs were at the Tritton Copper Operations:

  • At the Murrawombie mine, a loader tasked with stope backfilling in remote operation fell into a stope, with the operator still on board. The operator received major but non-life-threatening injuries. Incident investigations are in progress using an external expert. No clear cause has been established.

  • The second LTI was associated with the same incident; an employee involved in the emergency response action has suffered post incident psychological trauma.

Safety management systems are under review as a result of the significant incident.

At Cracow, a groundwater trigger level was exceeded. There was no impact to operations and investigations are underway.

3 All-In Sustaining and All-In Costs are based on copper produced

Tritton Copper Operations production of 5,270 tonnes was lower compared to the previous quarter (5,845 tonnes) and primarily relates to lower ore grades at both Tritton and Murrawombie.

Tritton Underground Mine (Tritton)

Tritton ore production was 258kt @ 1.21% copper, compared to 233kt @ 1.43% copper in the previous quarter.

The partial failure of a critical stope blast and a paste back-fill line blockage, both of which occurred in the previous quarter, impacted on stope extraction sequence in the March quarter, resulting in lower than planned copper grades. Productivity was impacted by equipment availability and labour turnover – steps have been taken to address both issues.

Aeris Resources Limited

Quarterly Activities Report | For the period ended 31 March 2021

==> picture [88 x 46] intentionally omitted <==

The Budgerygar development drive was completed during the quarter. A resource definition drilling campaign has commenced using two underground diamond drill rigs on double shift.

Murrawombie Underground Mine (Murrawombie)

Murrawombie ore production of 112kt @ 1.86% was lower than the prior quarter (146kt @ 2.12%) but in-line with plan. Lower than plan equipment availability had a short run impact and actions have been taken to rectify.

Ore Processing

Ore processed during the quarter at 382kt was higher than the previous quarter (371kt) due to higher opening stockpiles. A planned shutdown resulted in 48 hours downtime during the quarter.

Copper recovery of 92.97% for the quarter was lower compared to the previous quarter (93.76%) due to the lower copper head grade.

Costs

All-In Sustaining Costs (AISC) for the quarter at A$4.00/lb were higher than the previous quarter (A$2.85/lb) and were mainly due to the lower than planned copper production and inventory movements. YTD AISC is A$3.36/lb Cu.

Mining costs were higher in the quarter due to increased cement costs from higher paste filling activities and higher than planned mobile equipment maintenance costs.

Outlook

FY21 copper production guidance at Tritton Copper Operations has been revised to between 22,500 tonnes and 23,500 tonnes at an AISC of between A$3.60/lb and A$3.75/lb. The partial failure of a critical stope blast and a paste back-fill line blockage, both of which occurred in the December 2020 quarter, has resulted in stope extraction occurring out of sequence and lower than planned copper grades in the March and June 2021 quarters.

Exploration continues at the Constellation deposit with approval received during the quarter for 60 RC drill holes. From mid-April there will be three rigs (2 Diamond and 1 RC) drilling at Constellation.

Cracow Underground MIne (Cracow)

Cracow ore production of 130kt, whilst slightly lower than the previous quarter (135kt), was in-line with plan. Mining activities included the establishment of ladderways and vent rises to open higher-grade sequences for the remainder of FY21.

Cracow gold grade @ 4.11 g/t was lower than the previous quarter (4.40 g/t) due to sequencing. It is expected that the grade variation will continue into the following quarters. The long-term plan being developed is expected to show more grade variation from period to period than historically, as extending mine life is now being targeted whilst balanced against short-run high production grades. Previously the strategy has been to optimize the mine plan to maximise near-term gold grades – Aeris’ strategy since acquiring Cracow has been to find the economic balance on gold grade versus mine life extension through maximizing extraction of the Mineral Resource.

Ore Processing

Ore milled of 138kt was lower than the previous quarter (160kt) due to lower crusher and mill availability. The crushing circuit produced lower than expected crushed ore due to wet weather impacting ROM stocks and an unplanned crusher shutdown.

Gold recovery was slightly lower at 91.36% compared to the previous quarter (91.93%) due to increased volumes of lower grade stockpile material being processed during the quarter.

Costs

All-In Sustaining Costs (AISC) for the quarter at A$1,557/oz were lower than the previous quarter ($1,567/oz). Lower gold production and increased mine development were offset by lower mining costs. YTD AISC is A$1,453/oz.

Tailings Storage Facility No.2

During the quarter, construction continued on a new tailings storage facility at Cracow (TSF No.2) – see photos below. Cracow is currently discharging tailings into Tailing Storage Facility No.1 (TSF No.1) which will soon reach its capacity. Wet weather had a small impact on the construction progress with expected completion due mid-July 2021. Estimated total cost of TSF No.2 is approximately $14 million.

Outlook

FY21 gold production guidance at Cracow Gold Operations is between 70,000 to 75,000 ounces at an AISC of between A$1,525/oz and A$1,575/oz.

Aeris continues to review the long-term mine plan, targeting opportunities to increase ore production in line with the upgraded processing capacity.

Exploration drilling is on-going targeting both brownfields and greenfields exploration targets.

Exploration and Project Development

EXPLORATION – TRITTON COPPER OPERATIONS

The Tritton tenement package covers 2,330 km[2] in central western New South Wales. To date over 750,000 tonnes of copper, including the Current Mineral Resource deposits[1] , has been discovered within the southern half of the tenement package.

Following the completion of two regional airborne electromagnetic (AEM) surveys (totalling 678 km[2] ) covering a majority of the northern half of the tenement package, on-ground exploration has focused on activities within this area. The northern half of the tenement package, until recently, has not been subject to modern exploration and remains largely under-explored.

During the quarter an application for an additional exploration licence was submitted to the NSW Department of Mining, Exploration and Geoscience. The application is for ground located immediately north of the Exley Prospect and 10km north-west of the recently discovered Constellation Deposit. The ground has several geological features which are considered important regional vectors associated with copper mineralisation within the region. The application is expected to be granted in the June quarter.

Constellation Deposit

The Constellation Deposit is located approximately 45 kilometres north-east of the Tritton processing plant. The deposit was first detected via AEM survey and followed-up with ground moving loop (MLTEM) surveying. The MLTEM survey verified the EM response represented a legitimate bedrock conductor and identified two separate bedrock conductors.

Exploration activities continued at the Constellation Deposit during the quarter with ten additional diamond drill holes completed, with a majority intersecting copper sulphide mineralisation[2][3][4] . A summary of the results from each drill hole completed during the quarter is included below in Table 1.

Assay results have been received for drill holes TAKD007, TAKD009 and TAKD010. Drill hole TAKD007 returned a significant assay interval of 24.6m @ 1.45% Cu, 0.49g/t Au, 3.0g/t Ag, including:

  • 13.26m @ 2.00% Cu, 0.70g/t Au, 3.9g/t Ag and;

  • 2.6m @ 2.19% Cu, 0.62g/t Au, 5.5g/t Ag.

Diamond drill hole TAKD005 was designed to intersect the larger EM
plate, 80 metres along strike (south) from TAKD003 (27.1m @ 1.61%
Cu).
TAKD006 5.85m @ 4.60% Cu, 0.96g/t Au, 28.6g/t Ag.
Diamond drill hole TAKD006 was designed to intersect the larger EM
plate, 80 metres along strike (south) from TAKD001 (19.95m @ 2.41%
Cu).
TAKD007 24.6m @ 1.45% Cu, 0.49g/t Au, 3.0g/t Ag
Diamond drill hole TAKD007 was designed to intersect the larger EM
plate 80 metres down plunge from TAKD003.
TAKD008 Diamond drill hole TAKD008 was designed to test the continuation of
mineralisation 80m down plunge from TAKD007. The drill hole deviated
considerablyfromplan and was abandoned at 39.40 metres downhole.
TAKD009 0.7m @ 2.58% Cu, 0.61g/t Au, 6.9g/t Ag
Diamond drill hole TAKD009 tested the upper extents of the larger
MLTEM plate 80 metres up plunge from TAKD001. A 5m wide fault zone
was intersected at the target depth. Contained within the fault zone is a
fault bounded massive sulphide interval.
TAKD010 25.0m @ 0.66% Cu, 0.71g/t Au, 1.1g/t Ag
Drill hole TAKD010 tested the northern extents of the sulphide horizon
along strike from drill holes TAKD001 and TAKD003. The intersection is
interpreted to be close to the northern margin of the mineralised
system.
TAKD011
Assay pending
Diamond drill hole TAKD011 intersected the larger MLTEM plate 80
metres down plunge from TAKD005. The drill hole passed through an
approx. 1.8m thick semi massive sulphide interval from 346.6m down
hole.
TAKD012
Assay pending
Diamond drill hole TAKD012 intersected the larger MLTEM plate 160m
down plunge from TAKD07. The drill hole passed through an approx.
10m thick sulphide interval from 436m down hole.
**TAKD013 ** Diamond drill hole TAKD013 was designed to test the continuation of
mineralisation 80m down plunge from TAKD012. TAKD013 deviated
away from the planned target zone and consequently did not intersect
the projected sulphide horizon.
TAKD014
Assay pending
Diamond drill hole TAKD014 intersected the larger MLTEM plate 80
metres down plunge from TAKD012. The drill hole passed through an
approx. 19m thick sulphide interval from 475.6m down hole.

The mineralised interval reported from TAKD007 is the down plunge continuation of the high-grade copper intervals reported previously from TAKD001 and TAKD003 (Figure 3). All three drill holes intersected a thick sulphide package in excess of 20m. It is likely these intersections represent the thickest part of the mineralised system.

Figure 3 – Cross section through the Constellation Deposit.

==> picture [441 x 278] intentionally omitted <==

Drill hole TAKD009 targeted the mineralised system 80m up-plunge from the discovery hole TAKD001. A 0.7m thick massive sulphide lens was intersected within a bounding fault zone at the target horizon. Further work is required to determine the fault orientation and what impact the fault zone may have on mineralisation continuity further up-plunge toward TAKD002. Assay results for TAKD009 from the massive sulphide lens reported:

 0.7m @ 2.58% Cu, 0.61g/t Au, 6.9g/t Ag.

Drill hole TAKD010 tested the northern extents of the sulphide horizon along strike from drill holes TAKD001 and TAKD003. The drill hole intersected a broad zone of erratic stringer and disseminated chalcopyrite with only minor amounts of pyrite. TAKD010 returned an assay interval of 25.0m @ 0.66% Cu, 0.71g/t Au and 1.1g/t Ag including:

 7.0m @ 1.43% Cu, 1.77g/t Au, 2.4g/t Ag.

The absence of banded and massive sulphide textures and minimal pyrite may indicate the sulphide intersection from TAKD010 is close to the northern margin of the mineralised system.

EXPLORATION – CRACOW GOLD OPERATIONS

Since Aeris took ownership of the Cracow Gold Operations at the beginning of July 2020, one of the key focuses is mine life extension. The Company has budgeted to spend $13 million on exploration activities over the first two years of ownership, on both greenfields and brownfields exploration.

Key exploration activities undertaken during the quarter included:

  • Roses Pride Mineral Resource update;

  • Klondyke – Royal Mineral Resource Update; and

  • Underground resource definition drilling.

Roses Pride Mineral Resource Update

An updated Mineral Resource estimate for the Roses Pride deposit was completed during the quarter (refer to ASX Announcement “Roses Pride Mineral Resource Update” dated 6[th] January 2021). The updated Mineral Resource represents a 260% increase in total contained gold ounces compared to the previously reported Mineral Resource (December 2019). The updated Mineral Resource contains 177,000 tonnes at 4.6 grams per tonne gold for 26.1 thousand ounces of gold.

The updated Mineral Resource is based on a combination of additional drilling data and an alternate reporting schema. Further drilling is planned in the June quarter to continue drill testing the Roses Pride mineralised system.

– Klondyke Royal Mineral Resource Update

An updated Mineral Resource estimate for the Klondyke – Royal deposits was completed during the quarter (refer to ASX Announcement “Significant increase to Klondyke - Royal Mineral Resource” dated 22[nd] April 2021). The updated Mineral Resource represents a 324% increase in total contained gold ounces compared to the previously reported Mineral Resource (December 2019). The updated Mineral Resource contains 341,000 tonnes at 3.6 grams per tonne gold for 39.5 thousand ounces of gold.

The increased Mineral Resource inventory is based on a combination of a revision of the geological information, change in reporting criteria and additional mineralisation included from the June 2020 drill program.

Further drilling is planned in the June quarter at the Klondyke – Royal deposits. The drill program will be designed to complete infill drilling at each deposit.

Underground resource definition drilling

Resource definition drilling in the March quarter focused on testing extensions to known mineralised systems at the Royal and Sovereign deposits. Drilling at the Royal deposit successfully tested down plunge extensions to the mineralised structure mined previously. Drilling intersected gold mineralised over a 130m strike window (Figure X below). All intersections occured outside of the reported Mineral Resource footprint. Significant intersections include:

  • RSU526 - 4.55m @ 9.4g/t Au (2.8m true thickness)

  • RSU530A - 4.55m @ 3.5g/t Au (2.9m true thickness)

  • RSU528 - 6.75m @ 2.6g/t Au (4.4m true thickness)

  • RSU532 – 6.95m @ 2.1g/t Au (4.2 true thickness)

Figure 7: Long section view showing drill hole intersections from recent resource delineation drilling at the Royal deposit.

==> picture [438 x 256] intentionally omitted <==

Drilling completed at the Sovereign Deposit focused on testing the northern extents of the Inferred Mineral Resource. In total ten drill holes were completed, all of which intersected the main mineralised structure and an adjoining splay fault. Significant intersections include:

  • SVU128 - 2.7m @ 7.5g/t Au (2.2m true thickness)

EXPLORATION – TORRENS

The Torrens Project (EL6407), a joint venture between Aeris Resources (70% interest) and Kelaray Pty Ltd (a wholly owned subsidiary of Argonaut Resources NL), is exploring for iron-oxide copper-gold (IOCG) systems in the highly prospective Stuart Shelf region of South Australia. The Torrens Project is located on Lake Torrens, near the eastern margin of South Australia’s Gawler Craton and lies within 50 kilometres of Oz Minerals’ Carrapateena deposit and BHP’s Oak Dam West discovery, and 75 kilometres from BHP’s Olympic Dam mine.

No on-ground exploration activities were completed at the Torrens Project during the quarter. Data collected from the passive seismic survey was processed and finalised.

Criteria Commentary
Sampling Drilling
techniques 1. All samples have been collected from diamond drill core.
2. Samples taken over a mineralised interval are collected in
a fashion to ensure a majority are 1.0m in length, whilst the
HW and FW sample are as close to 1.0m as possible. Most
samples are collected at 1.0 metre intervals. HW and FW
intervals are taken as close to 1.0 metre.
Drilling 1. Drilling results reported are via diamond drill core (NQ
diameter).
techniques
Drill sample 1. Core recoveries are recorded by the drillers on site at the
drill rig. Core recoveries are checked and verified by an
recovery
Aeris Resources field technician and/or geologist.
2. Diamond drill core is pieced together as part of the core
orientation process. During this process depth intervals are
recorded on the core and checked against downhole
depths recorded by drillers on core blocks within the core
trays.
3. Historically core recoveries are very high within and outside
zones of mineralisation. Diamond core drilled to date from
the current drill program have recorded very high
recoveries and is in line with the historical observations.
Logging 1. All diamond drill core is logged by an Aeris Resources
geologist. Drill core is logged to an appropriate level of
detail to increase the level of geological knowledge and
further the geological understanding at each prospect.
2. All diamond core is geologically logged, recording
lithology, presence/concentration of sulphides, alteration,
and structure.
3. All geological data recorded during the core logging
process is stored in Aeris Resources AcQuire database.
4. All diamond drill core will be photographed and digitally
stored on the Company network.
5. Core is stored in core trays and labelled with downhole
meterage intervals and drill hole ID.
Sub-sampling 1. All samples collected from diamond drill core are
techniques and collected in a consistent manner. Samples are cut via an
automatic core saw, and half core samples are collected
sample
on average at 1 metre intervals, with a minimum sample
preparation length of 0.4 metre and a maximum length of 1.4 metre.

Criteria Commentary
2. No field duplicates have been collected.
3. The sample size is considered appropriate for the style of
mineralisation and grain size of the material being
sampled.
Quality of assay 1. All samples are sent to ALS Laboratory Services at their
data and Orange facility.
laboratory tests 2. Samples are analysed by a 3 stage aqua regia digestion
with an ICP finish (suitable for Cu 0.01-1%) – ALS method
ME-ICP41. Samples with Cu assays exceeding 1% will be
re-submitted for an aqua regia digest using ICP-AES
analysis – ALS method ME-OC46. Au analysis will be
performed from a 30g fire assay fusion with an AAS finish
(suitable for Au grades between 0.01-100ppm) – ALS
method Au-AA22. If a sample records an Au grade above
100ppm another sample will be re-submitted for another
30g fire assay charge using ALS method Au-AA25.
3. QA/QC protocols include the use of blanks, duplicates
and standards (commercial certified reference materials
used). The frequency rate for each QA/QC sample type is
5%.
Verification of 1. Logged drillholes are reviewed by the logging geologist
sampling and and a senior geologist. All geological data is logged
directly into Aeris Resources logging computers following
assaying
the standard Aeris Resources geology codes. Data is
transferred to the AcQuire database and validated on
entry.
2. Upon receipt of the assay data no adjustments are made
to the assay values.
Location of data 1. Drillhole collar locations are surveyed via a qualified
points surveyor.
2. All drillhole locations at Murrawombie are referenced in a
local mine grid. The Murrawombie Mine Grid origin (0E, 0N)
= 490306.92mE 6530140.69mN (AGD66). Grid North =
318.259 true. All drill hole locations at Tritton are
referenced in a local mine grid. The Tritton Mine Grid is
rotated 8.423° to the west from AGD66 Zone 55 true north.
3. Quality and accuracy of the drill collars are suitable for
exploration results.
4. Downhole surveys taken during drilling are completed by
the drill contractor using a Reflex gyroscopic tool
measuring azimuth and dip orientations every 30 metres or
shorter intervals if required.
Data spacing 1. Drill spacing at the Murrawombie deposit is spaced
and distribution between 20 metres to 80 metres down plunge. Drillhole
spacing along strike is similarly varied ranging between 20

2. The drill spacing at Murrawombie is appropriate to assess
the potential size and grade of a mineralised system to an
Inferred and Indicated Mineral Resource status.
Orientation of 1. All drillholes are designed to intersect the target at, ideally
data in relation to right angles. However, the limited drill locations available
does mean that for some drillholes the intersection angle
geological to mineralisation is more acute.

2. Each drillhole completed has not deviated significantly
from the planned drillhole path.
3. Drillhole intersections through the target zones are not
biased.
Sample security 1. Drillholes have not been sampled in their entirety. Sample
security protocols follow current procedures which include:
samples are secured within calico bags and transported to
the laboratory in Orange, NSW via a courier service or with
Company personal.
Audits or reviews 1. Data is validated when uploading into the Company
AcQuire database.

Section 2 - Reporting of Exploration Results

Criteria Commentary
Mineral tenement
and land tenure
status
1. The Tritton Regional Tenement package is located
approximately 45 kilometres north-west of the township of
Nyngan in central western New South Wales.
2. The Tritton Regional Tenement package consists of 8
Exploration Licences and 3 Mining Leases. The mineral and
mining rights are owned 100% by the Company.
3. The Murrawombie deposit is located within ML1280.
ML1280 is in good standing and no known impediments
exist.
Exploration done
by other parties
1. Regional exploration was completed over the currently
held tenement package by Utah Development Co in the
early 1960’s to early 1970’s. Australian Selection P/L
completed exploration throughout the 1970’s to late 1980’s
prior to NORD Resources throughout the late 1980’s and
1990’s. This included soil sampling and regional magnetics
which covered the Avoca, Greater Hermidale, Belmore
and Thorndale project areas. Principally exploration efforts
were focused on
the discoveryof

mineralisation. NORD Resources also completed some
shallow reverse circulation (RC) drilling over the Avoca
Tank Resource. Subsequent exploration efforts have been
completed by Tritton Resources Pty Ltd with the drilling
over a number of RC drillholes within the Greater
Hermidale region in the late 1990’s similarly focused on
heap leachable oxide copper mineralisation, prior to the
acquisition of the Tritton Resources Pty Ltd by Straits
Resources Limited in 2006.
Geology 1. Regionally mineralisation is hosted within early to mid-
Ordovician turbidite sediments, forming part of the
Girilambone group. Mineralisation is hosted within
greenschist facies, ductile deformed pelitic to psammitic
sediments, and sparse zones of courser sandstones.
2. Sulphide mineralisation within the Tritton tenement
package is dominated by banded to stringer pyrite –
chalcopyrite, with a massive pyrite-chalcopyrite unit along
the hanging wall contact. Alteration assemblages
adjacent to mineralisation is characterised by an ankerite
footwall and silica sericite hanging wall.
Drillhole 1. All relevant information pertaining to each drillhole has
information been provided.
Data 1. All historical assay results reported represent length
aggregation weighted composited assays. Compositing was applied to
intervals which nominally exceeded 0.5% Cu with a
methods
maximum of 3.0 metres internal dilution. No top cutting of
assay results was applied.
Relationship 1. Drillholes are designed to intersect the target horizon
between across strike at or near right angles. However, some drill
intersections have intersected mineralisation at shallow
mineralisation
angles and mineralised intersections are longer than the
widths and true thickness.
intercept lengths
Diagrams 1. Relevant diagrams are included in the body of the report.
Balanced 1. The reporting is considered balanced and all material

Criteria Commentary
Sampling Drilling
techniques 1. All samples have been collected via diamond drilling.
2. A majority of the samples are collected at 1 metre intervals.
A majority of samples are full core samples. For wider spaced
drill holes half core samples are taken. Sample weights range
from 2 kg to 4kg depending on sample length and half or
whole core.
3. Samples are sent to an independent and accredited
laboratory (ALS Brisbane). Samples less than 3kg are
pulverised to a nominal 85% passing 75 microns. If sample
weights exceed 3kg they are split via a rotary splitter and an
approximate 3kg sub sample retained and pulverised. After
pulverisation a 50g sample is collected for fire assay.
4. The sample size and sample preparation techniques are
considered appropriate for the style of mineralisation.
5. Industry prepared standards are inserted approximately 1 in
20 samples.
6. The samples are considered representative and appropriate
for this type of drilling.
Drilling 1. Drill holes are completed via diamond drilling (NQ2 diameter).
techniques
Drill sample 1. Core recoveries are recorded by the drillers on site at the drill
rig. Core recoveries are checked and verified by an Aeris
recovery
Resources field technician and/or geologist.
2. Diamond drill core is pieced together as part of the core
orientation process. During this process depth intervals are
recorded on the core and checked against downhole
depths recorded by drillers on core blocks within the core
trays.
3. Historically core recoveries are very high within and outside
zones of mineralisation. Diamond core drilled to date from
the current drill program have recorded very high recoveries
and is in line with the historical observations.
Logging 1. All diamond core is logged by an Aeris employee or a fully
trained contract geologist.
2. All diamond core is geologically logged, recording lithology,
vein quantity/texture/mineralogy, alteration and weathering.

2. Au assaying is via a 50g fire assay charge (Au-AA26) using a
AAS finish. Au assaying is completed at ALS Townsville
laboratory. Ag assaying is completed at the Brisbane
laboratory. A sample of 0.5g is collected and assayed using
an aqua regia digest.
3. QA/QC protocols include the use of blanks, duplicates and
standards (commercial certified reference materials used).
The frequency rate for each QA/QC sample type is 5%.
Verification of 1. Logged drillholes are reviewed by the logging geologist and
sampling and a senior geologist. All geological data is logged directly into
Logchief software at the core processing facility. The

including BP Minerals Australia, Australian Gold Resources Ltd,
ACM Operations Pty Ltd, Sedimentary Holdings NL and
Zapopan NL.
2. In 1995, Newcrest Mining Ltd (NML) entered into a 70 % share
of the Cracow Joint Venture. Initially exploration was
targeting porphyry type mineralisation, focusing on the large
areas of alteration at Fernyside and Myles Corridor. This focus
shifted to epithermal exploration of the western portion of the
field, after the discovery of the Vera mineralisation at Pajingo,
which shared similarities with Cracow. The Royal epithermal
mineralisation was discovered in 1998, with further discoveries
of Crown, Sovereign, Empire, Phoenix, Kilkenny and Tipperary
made from 1998 up to 2008
3. Evolution was formed from the divestment of Newcrest assets
(including Cracow) and the merging of Conquest and
Catalpa in 2012. Evolution continued exploration at Cracow
from 2012 to early 2020.
4. Aeris Resources purchased the Cracow Operation (including
the exploration and mining tenements) in July 2020.
Geology 1. The Cracow project area gold deposits are in the Lower
Permian Camboon Andesite on the south-eastern flank of the
Bowen Basin. The regional strike is north-northwest and the dip
20° west-southwest. The Camboon Andesite consists of
andesitic and basaltic lava, with agglomerate, tuff and some
inter-bedded trachytic volcanics. The andesitic lavas are
typically porphyritic, with phenocrysts of plagioclase feldspar
(oligoclase or andesine) and less commonly augite. To the
west, the Camboon Andesite is overlain with an interpreted
disconformity by fossiliferous limestone of the Buffel Formation.
It is unconformably underlain to the east by the Torsdale Beds,
which consist of rhyolitic and dacitic lavas and pyroclastics
with
inter-bedded
trachytic
and
andesitic
volcanics,
sandstone, siltstone, and conglomerate.
2. Mineralisation is hosted in steeply dipping low sulphidation
epithermal veins. These veins found as discrete and as
stockwork and are composed of quartz, carbonate and
adularia, with varying percentages of each mineral. Vein
textures include banding (colloform, crustiform, cockade,
moss), breccia channels and massive quartz, and indicate
depth within the epithermal system. Sulphide percentage in
the veins are generally low (<3%) primarily composed of
pyrite, with minor occurrences of hessite, sphalerite and
galena. Rare chalcopyrite, arsenopyrite and bornite can also
be found.
3. Alteration of the country rock can be extensive and zone
from the central veined structure. This alteration consists of
silicification, phyllic alteration(silica,sericite and other clay
