Tritton Copper Operations production of 5,845 tonnes was lower compared to the previous quarter (6,044 tonnes) and primarily related to lower ore production from the Tritton Underground Mine.

Tritton Underground Mine (Tritton)

Tritton ore production was 233kt @ 1.43% copper compared to 270kt @ 1.34% copper in the previous quarter. A partial failure of a critical stope blast in the initiating slot resulted in delays to the main stope blasting and a consequent shortage of broken ore stocks. Tritton mine is operated with a low number of actives stopes and therefore problems with a stope blast can result in a low broken ore stock event. Careful control of stope blasting is required to control the risk from limited flexibility. Priority is now placed on recovery of the delayed ore production.

The paste backfill pipeline was blocked in November due to a control system fault in the paste manufacture plant. Sufficient pipeline had been cleaned to allow paste running to the upper levels of the mine during December. Clearing the remainder of the pipeline is progressing quickly. Triton’s paste backfill system has an instantaneous capacity double the required average placement rate, so recovery from the blockages is expected to be rapid.

Production from the remaining upper-level remnant pillars restarted after a paste filling campaign. The remnant pillars are a small resource located in the higher levels of the mine. These higher-grade pillars (+2.5% Cu) were left between stopes in early years of the mine life, prior to the mine having a paste backfill system. Pillar recovery mining is slow and technically difficult due to deteriorated ground conditions and poor access. It has been progressing at a reasonable rate and is expected to be completed in the current year.

Murrawombie Underground Mine (Murrawombie)

Murrawombie ore production of 146kt @ 2.12% was higher than the prior quarter (141kt @ 2.04% g/t). Mobilisation of additional contract stope drilling capacity in the prior quarter resulted in a healthy quantity of drilled stocks. We have been able to draw on these stocks to partially offset the lower ore production at Tritton mine during the quarter.

Access decline development at Murrawombie has been paused to allow time for resource extension and grade control diamond drilling of the deposit below the current mining areas.

Ore Processing

Ore processed during the quarter at 371kt was lower than the previous quarter (412kt) due to the lower ore production from Tritton.

A planned plant shutdown for the grinding mill reline was completed in November. The opportunity was also taken to improve plant safety and productivity by installing new access platforms in the grinding area.

Copper recovery of 93.76% for the quarter was in line with previous quarter (94.00%).

Costs

All-In Sustaining Costs (AISC) for the quarter at A$2.85/lb were lower than the previous quarter of A$3.33/lb. Lower product handling charges and inventory movements contributed to the difference. A single shipment of concentrate that slipped from last quarter into early this quarter explains the inventory movement.

Cracow Underground Mine (Cracow)

Cracow ore production of 135kt was in line with plan but lower than the previous quarter (140kt). Variation in mine production is to be expected when we are testing the limits of mining capacity as we rebuild the long-term plan. Mining activities continued to focus on improving development and backfilling rates.

Cracow gold grade @ 4.4 g/t was lower than the previous quarter (4.7 g/t). The grade variation was expected as the scheduled stope sequence moved into lower grade areas. The new 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 developed as a target to be 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 Resource.

Ore Processing

Ore milled at 160kt was ahead of plan and well ahead of the previous quarter (145kt).

Over the past few months the processing team have been actively working towards de-bottlenecking both the crushing circuit and the processing plant with the goal of increasing mill throughput and thus metal recovered. This has now started to yield results, with the mill achieving a number of throughput tonnage records in the December quarter:

  • Highest daily milled tonnes: 1,951dmt on 14 October 2020

  • Highest weekly milled tonnes: 13,103dmt between 11 October 2020 – 17 October 2020

  • Highest monthly milled tonnes: 53,942dmt in October 2020

  • Highest quarterly milled tonnes: 160,446dmt in Q2 FY21

The processing team have now clearly demonstrated the processing plant has an annual capacity of 600,000 tonnes, exceeding the previous assumed limit of 570,000 tonnes per annum. Over the coming months a number of low-cost debottlenecking capital projects will commence to ensure the increased throughput rate can be sustained.

Feed to the processing plant that exceeds mine production comes from the significant stockpiles of low-grade material. Low grade stockpiles were accumulated from historical open pit mining and grades in this material are variable due to a lack of good historical records.

Aeris Resources Limited

Quarterly Activities Report | For the period ended 31 December 2020

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

Gold recovery was 91.93% for the quarter, compared to the previous quarter at 93.29%, and was impacted by the increased volumes of low-grade stockpile material processed during the quarter.

Costs

All-In Sustaining Costs (AISC) for the quarter at A$1,567/oz is higher than the previous quarter ($1,282/oz), impacted by lower metal production and increased mining costs due to increased mine development.

Tailings Storage Facility No.2

During the quarter, construction commenced on a new multi-stage tailings storage facility at Cracow (TSF No.2). Cracow is currently discharging tailings into Tailing Storage Facility No.1, (TSF No.1), which has reached its maximum allowable construction height. It is estimated that the construction of TSF No.2, stage 1, will be completed by June 2021 at an estimated cost of $14 million.

Investing in a multi-stage tailings storage facility with a capacity greater than 5 years reflects our investment thesis that the Cracow mine life can be extended by a sustained high quality exploration effort.

Outlook

FY21 gold production guidance at Cracow Gold Operations is unchanged at 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.

Further exploration drilling is planned in the first half of 2021 to support open pit Mineral Resource estimates. Underground drilling of near mine exploration targets will also continue with two underground drill rigs now on site. Downhole EM surveys on TAKD002 – TAKD004 will be undertaken during the March quarter.

Exploration and Project Development

EXPLORATION – TRITTON COPPER OPERATIONS

The Tritton tenement package covers 2,160km[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] area over a majority of the northern half of the tenement package, on-ground exploration has focused on activities over this area. The northern half of the tenement package, until recently, has not been subject to modern exploration and remains largely under-explored.

Constellation Deposit (previously known as Anomaly K)

The Constellation deposit is located approximately 45 kilometres north east from the Tritton Operation in central western New South Wales. The deposit was first detected via an airborne electromagnetic survey with follow-up ground moving loop (MLTEM) surveying completed in the previous quarter. The MLTEM survey verified the EM response represented a legitimate bedrock conductor. Two bedrock conductors were identified.

Exploration activities completed at the Constellation deposit during the quarter included the commencement of a first pass drill program designed to test whether the modelled conductive bodies (bedrock conductors) are associated with sulphides.

Four drill holes (TAKD001 – TAKD004) were completed by quarter end with three drill holes intersecting significant copper mineralisation. Drill holes TAKD001, TAKD003 and TAKD004 all targeted the larger eastern bedrock conductor. TAKD002 targeted a separate EM plate to the west.

At the larger EM plate to the east, copper sulphide mineralisation was intersected in TAKD001 and TAKD003. Both intersections are very similarly characterised by two higher grade copper intervals separated by a sulphide poor low grade copper horizon. Assay results reported from both drill holes include:

  • TAKD001 19.95m @ 2.41% Cu, 0.64g/t Au, 4.6g/t Ag from 197.2m including;

  • 5.6m @ 1.43% Cu, 0.53g/t Au, 2.4g/t Ag

  • 7.55m @ 4.71% Cu, 0.99g/t Au, 9.2g/t Ag

  • TAKD003 27.10m @ 1.61% Cu, 0.43g/t Au, 3.4g/t Ag from 233.90m including;

  • 6.30m @ 2.30% Cu, 0.47g/t Au, 4.8g/t Ag

  • 10.80m @ 2.37% Cu, 0.66g/t Au, 4.9g/t Ag

Drill hole TAKD004 targeted the northern margin of the modelled EM conductor and intersected a series of graphitic shear zones above and close to the target depth (190 metres down hole). The presence of several graphitic shears in the drill hole is worth noting. Similar graphitic shears at the Murrawombie deposit are often located proximal to mineralisation.

Down hole electromagnetic (DHEM) surveys will be completed on both TAKD003 and TAKD004 in the coming weeks to assist with refining the geometry of the conductive body which represents the massive sulphide component.

Figure 2 – Cross section through the Constellation deposit showing the hole path and location of sulphides intersected from drill holes TAKD001 – TAKD003.

==> picture [427 x 185] intentionally omitted <==

Drill hole TAKD002 was the second hole drilled at the Constellation deposit and was designed to intersect the smaller EM plate defined from the ground EM survey, approximately 300 metres west of the larger plate targeted by TAKD001 (refer Figure 1).

TAKD002 intersected a 3.55 metre thick massive sulphide interval from 61.05 metres down hole. Copper minerals identified include chalcopyrite, chalcocite and minor malachite and azurite. The presence of secondary copper minerals (chalcocite, malachite and azurite) indicates the drill hole intersection is associated with a supergene enriched copper halo below the base of oxidation. Reported assay results returned from the massive sulphide zone are:

 3.55m @ 22.56% Cu, 2.57g/t Au, 16.1g/t Ag

Core loss is recorded through the mineralised horizon (25% core loss) and within the surrounding turbidite sediments. It is not clear whether the core loss is associated with sulphide occurrence or the host turbidite sediments.

A down hole EM (DHEM) survey at TAKD002 has been completed. Results from the survey identified two EM conductors (refer Figure 3).

Aeris Resources Limited

Quarterly Activities Report | For the period ended 31 December 2020

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

The first conductive response between 60 metres to 65 metres down hole is associated with the massive sulphides intersected in TAKD002. The modelled plate is ~15m x ~15m and modelled with a high conductance (~5,000S).

The second conductive response is larger (20m x 60m) and located 15 metres off-hole, south, from TAKD002. The modelled conductance (10,000S to 20,000S) is exceptionally high for conductive bodies modelled within the Tritton tenement package. Current thinking is the off-hole EM conductor is likely to be massive sulphides due to the extremely high conductance and spatial location adjacent to the massive sulphides intersected in TAKD002.

Murrawombie Deposit

At the Murrawombie deposit, one exploration drill hole was completed during the quarter. Drill hole TMWD008 was collared from surface and targeted the projected down plunge extension to the known Murrawombie mineralised system from 250 metres to 300 metres beneath the current drilling footprint.

Although the drill hole did not intersect copper sulphide mineralisation, zones of chlorite and sericite alteration, including several graphitic faults were intersected. Similar alteration features and graphitic faults are observed proximal to the current mined lodes at Murrawombie. A down hole EM (DHEM) survey is planned to be completed on drill hole TMWD008 in the forthcoming quarter to detect for conductive bodies within a 200 metre radius. The results from the DHEM survey will guide further exploration drilling at Murrawombie.

Tritton – Budgerygar Corridor

Exploration drilling at the Tritton deposit was limited to one drill hole (TRGC1064). TRGC1064 was designed to target the projected down plunge continuation of the Tritton deposit approximately 150 metres below current drilling.

The drill hole intersected a very minor amount of sulphides (predominately pyrite based on visual observations). A DHEM survey is planned to be completed on the drill hole in the March quarter. The DHEM survey will be used to detect for conductive bodies within a 200 metre radius from the drill hole and assist with drill targeting.

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 Deeps drilling from surface;

  • Roses Pride Mineral Resource update;

  • Klondyke – Royal Mineral Resource Update; and

  • Underground near-mine targets

Roses Pride Deeps Surface Drilling

Surface drilling at the Roses Pride Deeps target continued during the quarter with a further two drill holes (CRD106 and CRD107) completed. A total of three drill holes have now tested the target.

Previous underground mining at Roses Pride is located within the “upper mineralised panel”, a favourable stratigraphic sequence within the Western Field. The underlying volcaniclastic stratigraphic sequence referred to as the ‘FoD’ has historically not been considered prospective. Recent stratigraphic reinterpretation across the Western Field has provided a greater understanding of the lateral extent, thickness and lithological facies variations within each unit, including the FoD.

Drill holes CRD106 and CRD107 were designed to test for lateral continuity of a potentially favourable stratigraphic unit (a coherent intermediate intrusive) located within the FoD at the intersection with the interpreted down dip continuation of the Roses Pride mineralised structure.

Both drill holes intersected the favourable coherent unit within the FoD stratigraphic domain. At the interpreted position of the Roses Pride mineralised structure a subtle fault with weak quartz veining was intersected. Due to the poor volume of epithermal quartz veining, these intersections are not considered prospective and significant assays are not anticipated (assay results are pending). In spite of this, the general target concept remains prospective. Further drilling will be considered along the newly identified stratigraphic horizon within the FoD further along strike (north). The intent of such drilling would be to test for sites of increased epithermal vein volume, in response to greater dilation along the Roses Pride mineralised structure.

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 first half of 2021 to continue drill testing the Roses Pride mineralised system.

Klondyke – Royal Mineral Resource Update

Work on an updated Mineral Resource estimate for the Klondyke and Royal deposits commenced during the quarter. The updated Mineral Resource estimate is being prepared following the completion of an RC drill program across both deposits in the September quarter (refer to September 2020 Quarterly Activities Report).

The Klondyke and Royal deposits are high grade shoots which form along the same mineralised structure. The RC drill program, totalling 23 drill holes, was designed to infill around existing drill hole data above the higher grade Klondyke deposit and test the extents of mineralisation along the structure between the two deposits.

Underground near-mine targets

A detailed geological review defining additional drill targets surrounding underground infrastructure was completed during the quarter. The review identified a significant number of targets in proximity to current underground workings.

A second drill rig arrived onsite and commenced drilling on the 8[th] January to accelerate drill testing of the near mine targets, in-conjunction with infill grade control drilling.

Drilling in the December quarter primarily focused on testing the Kenneth exploration target. The Kenneth drill target, located along strike from the currently mined Killarney deposit, represents an approximate 350 metre x 100 metre target horizon. During the quarter a total of six drill holes were completed at the Kenneth target. The drill holes have intersected significant quartz vein volume with some epithermal vein textures through the target horizon.

Significant assay results returned during the quarter from the Kenneth drilling include:

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.

A trial passive seismic survey was completed at Lake Torrens within the quarter. The aim of the survey is to more accurately identify the cover sequences above the basement rocks to assist with refining geological and geophysical models. Processing and interpretation of the passive seismic data will occur in the March quarter.

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.

ML3229. ML3229 is in good standing and no known
impediments exist.
Exploration 1. The Cracow Goldfields were discovered in 1932, with the
identification of mineralisation at Dawn then Golden Plateau
done by other
in the eastern portion of the field. From 1932 to 1992, mining of

produced
approximately 850koz of Au metal. Exploration across the
fields and nearby regions was completed by several identities
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 countryrock can be extensive and zone

from the central veined structure. This alteration consists of
silicification, phyllic alteration (silica, sericite and other clay
minerals) and argillic alteration in the inner zone, grading
outwards to potassic (adularia) then an outer propylitic zone.
Gold is very fined grained and found predominantly as
electrum but less common within clots of pyrite.
Drillhole 1. All relevant information pertaining to each drillhole has been
information provided.
Data 1. Reported significant intervals are based on a minimum width
aggregation of 1.0m, minimum Au grade 1g/t Au, maximum of 2m of
below cut-off material (<1g/t Au).
methods
Relationship 1. Drillholes have been designed to intersect the mineralised
between structure at a high angle.
mineralisation 2. As a generalisation drillhole intersections through the
widths and mineralised structure at an acute angle (~30-60°).
intercept 3. Reported significant intervals are based on a minimum width
lengths of 1.0m, minimum Au grade 1g/t Au, maximum of 2m of
below cut-off material (<1g/t Au).
Diagrams 1. Relevant diagrams are included in the body of the report.
Balanced 1. The reporting is considered balanced and all material
