Early-Stage Air-core Drilling Results Point to New Porphyry Discovery at Toora West
Encouraging indications from shallow air-core drilling ~15km NW of the Thursday’s Gossan Prospect highlight “province-scale” exploration potential across Stavely’s tenure
-
➢ First-pass air-core drilling at the Toora West prospect, ~15km north-west of Thursday’s Gossan, has returned strong indications of an underlying copper porphyry system.
-
➢ Assay results include:
-
1m at 0.15% Cu from 58m down-hole and 3m at 0.34% Cu from 64m, including: 1m at 0.61% Cu and 2.46g/t Ag from 64m (STWAC029)
-
3m at 0.17% Cu from 35m down-hole, including: 1m at 0.32% Cu from 35m and 1m at 0.14% Cu from 45m (STWAC030)
-
3m at 0.11% Cu from 39m down-hole and 1m at 0.18% Cu from 50m to the end-of-hole (STWAC031)
-
-
➢ An additional 18 air-core holes have been completed to in-fill and extend the original wide-spaced nominal 200m by 400m drill program.
-
➢ Visual observation from both the original and follow-up air-core programs has noted:
-
Widespread weak-to-moderate pyrite, chalcopyrite, secondary chalcocite and molybdenite sulphide mineralisation over an area ~1km east-west to 2km northsouth which remains open in all directions;
-
Mineralisation is associated with alteration interpreted as inner-propylitic to outer potassic in character - typically a lower-grade zone - meaning the target higher-grade potassic core is likely to be near-surface.
-
➢ Implications are:
-
The observation of secondary chalcocite overgrowing other sulphide phases clearly indicates a degree of copper remobilisation in the weathering profile and early shallow air-core results may not reflect the true primary grades;
-
At this stage, the Toora West prospect has the geochemical signature of a coppermolybdenum porphyry;
-
If confirmed by follow-up diamond drilling, the Toora West prospect represents a blind, grass-roots porphyry discovery that will further substantially upgrade the discovery potential within the Stavely Volcanic Arc;
-
Stavely has the largest and most prospective tenure in the Stavely Volcanic Arc and is by far the most active explorer in this emerging copper province.

ASX Announcement 12 May 2021
==> picture [145 x 44] intentionally omitted <==
Stavely Minerals Limited (ASX Code: SVY – “Stavely Minerals”) is pleased to report highly encouraging first-pass air-core drilling results from the Toora West porphyry prospect in Exploration Licence 5478, part of its 100%-owned Stavely Copper-Gold Project in Victoria (Figures 1 and 2).
Toora West is located ~15km north-west of the Cayley Lode discovery at the Thursday’s Gossan prospect, where a major resource drill-out is continuing.
Commenting on the latest results, Stavely Minerals’ Executive Chairman, Chris Cairns, said:
“We are very excited to see clear indications of a second emerging discovery in the Stavely Volcanic Arc. While the shallow Mineral Resource definition drill program at Thursday’s Gossan is at an advanced stage, a new early-stage discovery at Toora West would confirm the prospectivity of the entire Stavely Volcanic Arc for further discoveries, further leveraging our dominant, first-mover position in this under-explored district.
“As the natural progression from intensive drill-out to more engineering and metallurgicallybased economic studies at Thursday’s Gossan plays out, the focus of our geology team will shift to testing regional targets.
“Given the lack of systematic exploration in the Stavely Volcanic Arc, we simply do not know if Thursday’s Gossan is the best opportunity out there or whether it was the easiest to identify given that it sits in a ‘window’ of no cover while the rest of the Stavely Belt – including the Stavely Belt-equivalent Narrapumelap Belt and the Elliot Belt in our EL006870 – are largely unexplored under shallow cover.
“We recently contracted CGG Geophysics to fly a gravity gradiometer survey and those data, in conjunction with high-resolution magnetics data collected concurrently, will provide a proprietary baseline dataset to guide exploration in the district for many years to come.
“Despite having worked in this part of western Victoria for the past seven years, I can’t help but feel that we may be in the early part of this discovery journey in an emerging copper province in a first-world jurisdiction, just at a time when the world requires a secure and increasing supply of copper to underpin the transition to a low-carbon future.
“Additionally, and this may have fallen off the radar of many investors, Stavely Minerals also owns the Mt Ararat VMS deposit which contains a resource of 1.3Mt at 2.0% copper, 0.5g/t gold, 6g/t Ag and 0.4% zinc (as detailed in Stavely Minerals’ 2020 Annual Report). We have recently drilled two deeper diamond drill holes under the existing resource at this deposit and we plan to drill a further two deep diamond drill holes another 100m below the recent holes.
“A revised Mineral Resource Estimate for Mt Ararat is likely to highlight the opportunity for an additional satellite source of copper-gold-silver and zinc mineralisation which could be included in economic studies for the development of Thursday’s Gossan.
“With a potential emerging discovery at Toora West, the question now becomes will there be three sources of copper mineralisation for a potential development or will there be even more copper deposits identified with further exploration of our dominant tenure position? I’d be happy to take a bet that there will be.”

In March 2021, Stavely Minerals completed a first-pass 32-hole air-core drilling program at the Toora West porphyry prospect in EL5478. Previous diamond drilling at Toora West targeted subtle magnetic features and may have intersected barren post-mineral intrusions that were magnetic due to a lack of magnetite-destructive porphyry-style alteration.
The air-core program was designed as wide-spaced reconnaissance drilling on nominal 400m spaced lines and 200m collars on the lines. Based on visual observations of chalcopyrite,
Page 4

secondary chalcocite and molybdenite sulphide mineralisation in drill holes STWAC029 to 031, a further 18 follow-up holes were completed to tighten the drill pattern to 200m lines and 100m-spaced collars on the lines (Figures 3-5). Assay results are pending for the followup air-core program.
From the initial program, assay results have confirmed the visual observations:
-
STWAC029 ▪ 1m at 0.15% Cu from 58m down-hole, and
-
3m at 0.34% Cu from 64m, including:
- 1m at 0.61% Cu and 2.46g/t Ag from 64m
o STWAC030
▪ 3m at 0.17% Cu from 35m down-hole, including:
- 1m at 0.32% Cu from 35m, and
▪ 1m at 0.14% Cu from 45m
- STWAC031
▪ 3m at 0.11% Cu from 39m down-hole, and
▪ 1m at 0.18% Cu from 50m to the end-of-hole
Drill sections are presented in Figures 6 to 8.
The observation of secondary chalcocite overgrowing other sulphide phases clearly indicates a degree of copper remobilisation in the weathering profile and therefore early shallow results in air-core drilling may not reflect true primary grades.
A series of follow-up diamond drill holes will be planned once assay results from the followup air-core program have been received.
Widespread weak-to-moderate pyrite, chalcopyrite, secondary chalcocite and molybdenite sulphide mineralisation occurs over an area approximately 1km east-west to 2km northsouth, and the noted mineralisation remains open in all directions.
Mineralisation is hosted in granodiorite, dacite porphyry and diorite intrusive phases as well as country-rock andesite and sandstone units.
Mineralisation is associated with epidote alteration, indicating a possible inner-propylitic position, while quartz veins display ‘pinking’ on the margins, likely a potassic feldspar selvedge to the veins, indicating a more proximal outer-potassic signature (Figure 9). The nearproximal indication of inner-propylitic to outer-potassic alteration is considered very encouraging as this zone is typically lower-grade and would indicate that the target highergrade potassic core is likely near-surface.
At this early stage, the Toora West prospect has the geochemical signature of a coppermolybdenum porphyry with molybdenum assays to 119ppm and lesser silver associated with copper mineralisation.
If confirmed by follow-up diamond drilling, the Toora West porphyry prospect represents a blind, grass-roots porphyry discovery under approximately 30m of transported cover material which would reinforce the outstanding potential to make additional copper discoveries within the Stavely Volcanic Arc outside of the advanced Thursday’s Gossan prospect.

ASX Announcement 12 May 2021

Stavely Minerals has the largest and most prospective tenure in the Stavely Volcanic Arc and is by far the most active explorer in this emerging copper province.
As the shallow Mineral Resource definition drilling program at the Cayley Lode discovery continues to progress well (with access to the southern paddock assumed from 1 October 2021), the overall program will be completed towards the end of the year, with a maiden Mineral Resource estimate due out shortly thereafter.
This will pave the way for economic studies including engineering, metallurgy, environmental and plant design as the foundation for Scoping and Pre-Feasibility Studies.
With the deeper exploration potential below the Low Angle Structure (LAS) – ie. that material that may be available for a potential underground development - to be pursued with a lower intensity drilling program at Thursday’s Gossan, the focus of the Company’s exploration team will shift to priority regional opportunities, such as Toora West.
Given the lack of systematic exploration in the Stavely Volcanic Arc, it is unknown if Thursday’s Gossan is the best opportunity out there or whether it was the easiest to identify given that it sits in a ‘window’ of no cover while the rest of the Stavely Belt, including the Stavely Belt equivalent Narrapumelap Belt and the Elliot Belt in Stavely Minerals’ large Exploration Licence 006870, are largely unexplored under shallow cover (Figure 10).
Stavely Minerals will continue in its endeavour to unlock value for shareholders, taking full advantage as a first-mover, through effective and systematic exploration in this underexplored emerging copper province.

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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. |
All aircore (AC) drill holes have been routinely sampled at 1m intervals. Samples for every metre are collected by the drill offsider from the cyclone directly into a bucket (if dry) or, if wet, through a garden sieve to separate the coarse fraction from the sludge. The sample is then placed on a black plastic sheet on the ground. Samples are placed for every metre in rows of 10. Selected one-metre intervals are sampled for assay analysis. For the 1m samples – a representative grab sample is collected by mixing up (to homogenise) samples before using a scoop and placed in pre-labelled calico bags. Samples are no more than 3kg. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Sample representivity was ensured by a combination of Company Procedures regarding quality control (QC) and quality assurance/ testing (QA). Certified standards and blanks were inserted into the assay batches. |
|
| 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 sampling techniques are considered industry standard for the Stavely work program. The aircore drill samples were submitted to Australian Laboratory Services (“ALS”) in Adelaide, SA. Laboratory sample preparation involved:- sample crush to 70% < 2mm, riffle/rotary split off 1kg, pulverize to >85% passing 75 microns. |
|
| 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 |
Aircore drilling was carried out using a Wallis Mantis 80 Aircore rig mounted on a Toyota Landcruiser base. The AC rig used a 3.5” blade bite to refusal, generally just below the fresh rock interface. |

| oriented and if so, by what method, etc). |
||
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Aircore drill recoveries were visually estimated as a semi- quantitative range and where there were significant recovery issues they were recorded in the comments. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Recoveries were generally high (>90%). A large majority of the samples were wet. |
|
| 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. |
No sampling issues, recovery issues or bias were identified and it is considered that both sample recovery and quality is adequate for the drilling technique employed. |
|
| 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. |
Geological logging of samples followed Company and industry common practice. Qualitative logging of samples including (but not limited to) lithology, mineralogy, alteration, veining and weathering. A small representative sample was retained in a plastic chip tray for future reference and logging checks. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
All logging is quantitative, based on visual field estimates. | |
| The total length and percentage of the relevant intersections logged. |
Digital chip logging, with digital capture, was conducted for 100% of chips logged by Stavely’s geological team. |
|
| 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. |
One metre individual and EOH samples were collected as grab samples. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Company procedures were followed to ensure sub- sampling adequacy and consistency. These included, but were not limited to, daily work place inspections of sampling equipment and practices. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
Blanks and certified reference materials are submitted with the samples to the laboratory as part of the quality control procedures. |

| 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. |
1m AC grab samples were analysed by multielement ICPAES Analysis - Method ME-ICP61. A 0.25g sample is pre-digested for 10-15 minutes in a mixture of nitric and perchloric acids, then hydrofluoric acid is added and the mixture is evaporated to dense fumes of perchloric (incipient dryness). The residue is leached in a mixture of nitric and hydrochloric acids, the solution is then cooled and diluted to a final volume of 12.5mls. Elemental concentrations are measured simultaneously by ICP Atomic Emission Spectrometry. This technique approaches total dissolution of most minerals and is considered an appropriate assay method for porphyry copper-gold systems. This technique is a four acid digest with ICP-AES or AAS finish. The 1m grab splits were also analysed for gold using Method Au-AA23. Up to a 30g sample is fused at approximately 1,100oC with alkaline fluxes including lead oxide. During the fusion process lead oxide is reduced to molten lead which acts as a collector for gold. When the fused mass is cooled the lead separates from the impurities (slag) and is placed in a cupel in a furnace at approximately 900oC. The lead oxidizes to lead oxide, being absorbed by the cupel, leaving a bead (prill) of gold, silver (which is added as a collector) and other precious metals. The prill is dissolved in aqua regia with a reduced final volume. Gold content is determined by flame AAS using matrix matched standards. For samples which are difficult to fuse a reduced charge may be used to yield full recovery of gold. This technique approaches total dissolution of most minerals and is considered an appropriate assay method for detecting gold mineralisation. |

product of interval x corresponding interval grade %) divided by sum of interval length. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent reporting is used or applied. | |
| Relationship between mineralisatio n 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. |
Due to the early stage of exploration, the geometry and extent of any primary mineralisation is not known. |
| 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’). |
Mineralisation results are reported as “down-hole” intervals as true widths are not yet known. |
|
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
All relevant exploration data is shown in diagrams and discussed in the text. |
| 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 to avoid misleading reporting of Exploration Results. |
All drill hole results received have been reported in this announcement. No holes are omitted for which complete results have been received. |
| 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; |
All relevant exploration data is shown on figures and discussed in the text. |
