01 Sept 2021 ASX Announcement
JUNE 2021 QUARTERLY ACTIVITIES REPORT Amended
Classic Minerals has made significant progress at Kat Gap during the quarter as it strives to become a gold producer.
Highlights of the quarter include:
-
Assay results returned for infill RC drilling testing the gap between oxide and deeper fresh rock high-grade gold mineralisation at Kat Gap.
-
Advancing engineering, mining and metallurgical studies at Kat Gap, and
-
IGO have made further progress at Classic’s Fraser Range Project.
A total of 29 holes for 2,588 metres were drilled during the quarter by the Company.
RC drilling was focused solely on Kat Gap with work concentrating on filling in the gap created artificially between shallow drilling of the oxide profile and deeper drilling for the down dip extensions into fresh rock. If the gap could be filled in by zones of higher-grade gold mineralisation, then the final optimisation work may drive pit designs deeper allowing the Company to access more minable ounces.
IGO have continued working on their recently identified high conductance discrete EM anomaly over the Thylacine and Sabretooth area (now known as the Moa target) within a broader stratigraphic conductor.

continue to advance in Q4 FY2021 concentrating on:
-
Targeting the interpreted plunge component of high-grade gold mineralisation with deeper RC drilling;
-
Drilling priority targets out in the granite within the large auger soil gold anomaly west of the main granite-greenstone contact at Kat Gap;
-
Advancing all aspects of the mining plan at Kat Gap;
-
Acquisition of necessary mining equipment for Kat Gap, and
-
Continuing to raise capital & pay down debt & liabilities to improve the financial position of the Company.
1. KAT GAP
During the quarter, Classic completed a program of infill RC drilling which was completed back in April. The drilling program consisted of 28 deep infill holes for 2,548m and a single shallow RC hole for 40m. Results for this program were received in mid-June.

Deep Infill RC drilling[1]
The 28-hole deep infill RC drilling program (FKGRC350-377) covered an area approximately 120m along strike to the north of the Proterozoic dyke (See Figure 3.0). The infill holes were focused on testing a gap that had been artificially created between previous shallow RC holes testing the oxide profile and much deeper previous RC holes testing the down-dip extent of the main granitegreenstone contact lode. If the gap could be filled in by zones of gold mineralisation then final optimisation work may drive pit designs deeper allowing access to more minable gold bearing ore. The holes were drilled to an average depth of 100m below surface and were drilled on 20m x 10m and 10m x 10m grid spacings.
The drilling intersected significant zones of gold mineralisation in the gap between previous shallow RC holes and deeper RC holes testing the down-dip / down plunge extents (See figures 4, 5, 6 and 7). Further work will now be urgently undertaken to include these new gold intersections into the current resource model. Once this has been completed further optimisation work will be carried out. This work coupled with the outcomes of the bulk sampling program will aid greatly in final pit design work.
Better results from the deep infill holes include:
-
7m @ 2.67g/t Au from 71m in FKGRC350
-
3m @ 6.74g/t Au from 101m including 1m @ 15.00g/t Au from 102m in FKGRC360.
-
4m @ 18.97g/t Au from 76m including 2m @ 33.75g/t Au from 77m in FKGRC362.
-
2m @ 10.73g/t Au from 74m including 1m @ 19.90g/t Au from 74m in FKGRC367.
-
1m @ 14.20g/t Au from 69m in FKGRC368.

Shallow RC Drill hole[2]
A single shallow RC hole (FKGRC378) was completed to a depth of 40m. The hole was drilled close to existing high-grade holes FKGRC061 which returned 9m grading 15.21 g/t from 22m and FKGRC018 which returned 10m grading 30.78 g/t from 28m (See figures 4 and 5). The hole was drilled to provide additional material for advanced metallurgical testwork and aid in further Research and Development studies.
The hole returned the highest-grade intersection ever recorded at Kat Gap, 10m grading 40.54 g/t gold from 26.50m including 0.50m grading 592.00 g/t gold from 28.50m.

FRASER RANGE
The Company refers to the ASX announcements of 17 June 2019 and 05 July 2019 wherein Classic entered into the Earn-in and Joint Venture Agreement with Independence Newsearch Pty Ltd, a 100% owned subsidiary of IGO Limited (ASX: IGO) (“IGO”). More details of the transaction can be found in these two announcements.
The following is an update of progress on exploration carried out during the June 2021 quarter by IGO on the Fraser Range tenements.
In June 2021, IGO notified Classic of its election to acquire a 51% interest in the joint venture tenements after spending $1,500,000 on exploration; and its intention, at its option, to spend a further $1,000,000 exploring the Tenements over the next two years to increase its joint venture interest to 70%. Classic has provided signed transfers of 51% of the tenements to IGO and received $550,000 (including GST) on 8 June 2021.

One diamond drillhole (21AFDD103) was completed at the Moa VMS prospect for a total length drilled of 313m. The hole was targeting a discrete Moving Loop Electromagnetic (MLEM) plate conductor interpreted to be steeply west dipping and of high conductance (~13,000S) located approximately 100m below surface. The conductor lies along a long NE-trending stratigraphic unit identified in both magnetics and airborne EM.

Figure 9: Diamond Drillhole Collar Location Plan – Moa VMS Prospect.
Diamond drillhole 21AFDD103 intersected predominantly sheared metasediments of the Snowy’s Dam Formation with minor mafic granulites and narrow zones of meta-banded iron formation (BIF). Multiple thick zones of disseminated and stringer pyrrhotite occur within sheared quartz garnet intervals and include variable disseminated graphite. Trace chalcopyrite and sphalerite occur sporadically within these sequences.

C) Coarse stringer pyrrhotite within banded metasediments at 220m. D) Blebby pyrrhotite within coarse quartz-garnet-biotite at 221m.
The downhole EM survey confirmed that pyrrhotite-graphite bearing lithology intersected from 138m to 168m was the source of the high EM conductance. The survey data showed stacked in-hole anomalies between 140m and 170m downhole, which correlates well with the position of the single plate modelled from the MLEM data and conclusively explains the source of the conductor. Assays are expected to be received in Q1FY22.

Classic had a busy period for the quarter ended 30 June 2021 with a number of significant events taking place.
On 22 April 2021 the Department of Mines, Industry Regulation and Safety granted Classic Mining Lease M74/249. The lease is valid for the period 22 April 2021 to 22 April 2042. Given the progression to mining the Company was making, the Board appointed Ms Gillian King as a non-executive director of the Company. Ms King adds to the Board on many fronts including diversity, human resources and indigenous affairs. The Company now has a Board matrix with expertise in finance, international business, engineering, mine management, human resources and indigenous affairs.
The Gekko gold processing plant was successfully assembled and commissioned d at Classic’s testing site in Gnangara WA. During May and June, the Gekko plant was delivered to the Kat Gap tenement and will be reassembled during Q 1 & 2.
Pursuant to the grant of Mining Lease, Classic lodged the two remaining environmental approval applications to DMIRS for the proposed Kat Gap Mine development footprint. The endorsement of these application will permit Classic to commence the mining operations at Kat Gap.
Another significant development was the approval for trial mining at Kat Gap via the extraction of a Bulk Sample. Classic will be permitted to expose between 3,000 – 5,000 tonnes (t) of ore at between 4 and 6 g/t Au for between 350 – 1,000 ounces of gold (Au). The Company intends to commence this activity during the 1[st] Quarter of 2021-2022 financial year.
During the quarter our joint venture partner for the Fraser Range tenements IGO Newsearch Pty Ltd, a wholly owned subsidiary of IGO Limited (ASX: IGO), exercised their rights to acquire 51% of the Fraser Range tenements pursuant to satisfying the conditions in the Agreement. Classic received $ 500,000.00, exclusive of GST, for this transaction.
Other funding activities included a second draw against eligible Research & Development (R&D) activities from industry funder Radium Capital, various capital raising and equity-fordebt exchange with willing suppliers.
Classic enters the 1[st] quarter of 2022 Financial Year in a strong position to become a low-cost gold producer.

| **SECTION1 – FRASERRANGEDRILLINGRESULTS – SAMPLINGTECHNIQUES ANDDATA ** | |
|---|---|
| JORC Criteria | Commentary |
| Sampling techniques |
• Sampling included in this public report for the Fraser Range is diamond core drilling (DD) |
| Drilling techniques | • DD: − DD holes were drilled by track or truck mounted rigs owned and operated by West Core Drilling Pty Ltd, or Frontline Drilling Australia Pty Ltd or DDH1 Drilling Pty Ltd. − All holes were collared from surface with either PQ-core (85mm diameter) or PQ rock-rolled, which was then reduced to HQ-core (63.5mm diameter) and subsequently NQ2-core (50.6mm diameter) at depths directed by the IGO geologist. − All HQ and NQ core collected was oriented using REFLEX ACT III-H or N2 Ezy-Mark orientation tools. |
| Drill sample recovery |
• Sample recovery for the DD core loss was recorded by the drillers with any core loss intervals noted on annotated wooden blocks inserted into the core boxes by the driller. • For recovery checking and orientation marking purposes, the DD core was reconstructed by IGO’s geologists into continuous runs in an angle iron cradle. • DD recoveries were quantified as the ratio of measured core recovered length to drill advance length for each core-barrel run. There were no material core-loss issues or poor sample recoveries over the sampled intervals. • DD down hole depths were checked against the depth recorded on the core blocks, and rod counts were routinely carried out and marked on the core blocks by the drillers to ensure the marked core block depths were accurate. |
| Logging | • Qualitative logging for the DD core was completed using IGO’s in-house logging legends and included lithology, mineralogy, mineralisation, |
| structural, weathering, colour and other features of the samples. • Quantitative logging of DD core was completed for geotechnical purposes. • The total lengths of all drill holes have been logged. • Photographs of all DD trays are taken and retained on file with the original core trays stored in the core library at the 100% IGO owned Nova Operation. • The logging is considered adequate to support downstream exploration studies and follow-up drilling with reverse circulation percussion (RC) or further DD. |
|
| Sub-sampling techniques and sample preparation |
• The DD core was generally subsampled into 0.5 to 1m half-core by cutting the core longitudinally on an automated wet-diamond-blade core saw. Exceptions were for duplicate samples of selected intervals, where quarter-core subsamples were cut from the half-core. All samples submitted for assay were selected from the same side of the core. • The primary tool used to ensure representative drill core assays was monitoring and ensuring near 100% core recovery. • The ALS laboratory the samples are oven dried (12 hours at 100°C), followed by coarse crushing in a jaw-crusher to 100% passing 10 mm, then pulverisation of the entire crushed sample in low Cr-steel pulverising bowls to a particle size distribution (PSD) of 85% passing 75m. A 300g sub-sample pulp sample is then split to serve as the analysis lot. • Quality control procedures involve insertion of certified reference materials, blanks, and collection of duplicates at the pulverisation stage. Results were within acceptable limits. |
| Quality of assay data and laboratory tests |
• No geophysical tools or portable XRF instruments were used to determine any element concentrations. • CRMs and blanks were routinely inserted at frequencies between 1:10 and 1:20 samples for DD sample streams. • The DD samples will be analysed by: − Lithium borate fusion and four- acid digestion, with inductively coupled plasma atomic emission spectroscopy (ICP-AES) ME- ICP06) finish for Al, Fe, Na, Ti, Ba, K, P, Ca, Cr, Mg, Mn, Si, and Sr, or an inductively coupled plasma mass spectrometry (ICP- MS; ME-MS81) finish for Ba, Ce, Cr, Cs, Dy, Er, Eu, Ga, Gd, Hf, Ho, La, Lu, Nb, Nd, Pr, Rb, SM, Sn, Sr, Ta, Tb, Th, Tm, U, V, W, Y, Yb, and Zr. Four- acid digestion of samples, with ICP-AES finish (ME-ICP61) for Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W, and Zn. − Platinum, Pd and Au were analysed by fire assay and ICP-AES finish (PGM-ICP23). − The digestion methods can be considered near total for all elements. − Loss on ignition (LOI) was determined by robotic thermo gravimetric analysis at 1000C (ME-GRA05). • Assay results are pending and quality control samples are results are yet to be reviewed |
| Verification of sampling and assaying |
• Assay results are pending and as such have not yet been verified. |

| **SECTION1 – FRASERRANGEDRILLINGRESULTS – SAMPLINGTECHNIQUES ANDDATA ** | |
|---|---|
| JORC Criteria | Commentary |
| Location of data points |
• Surface hole collar locations were determined using a handheld Garmin GPS unit and averaging for 90 seconds with an expected accuracy of ±6m for easting and northing. • Drill path gyroscopic surveys were completed at 18m interval down hole using an Axis Champ Gyro for DD holes. • The grid system is GDA94/MGA Zone 51 and elevations are in AHD. |
| Data spacing and distribution |
• The DD drilling target conductive plates generated from surface geophysics (moving loop EM) and/or anomalous geochemistry generated from RC and soil sampling. • Assay results are still pending – compositing may be applied after results are received |
| Orientation of data in relation to geological structure |
• DD from the surface was designed to cross the conductive plate targets at a high angle. Holes have been drilled to provide stratigraphic coverage. • True widths of the intervals are often uncertain as the drilling is aimed at finding anomalies not MRE definition. • The possibility of bias in relation to orientation of geological structure is currently unknown. |
| Sample security | • The chain-of-sample custody to ALS is managed by the IGO staff. • The DD core was wet cut using a diamond bland and sampled at IGO’s Nova Operation by IGO staff and contractors • A sample reconciliation advice is sent by the ALS-Perth to IGO’s Geological Database Administrator on receipt of the samples. • Any inconsistences between the despatch paperwork and samples received is resolved with IGO before sample preparation commences • Sample preparation and analysis is completed only at ALS-Perth. • The risk of deliberate or accidental loss or contamination of samples is considered very low. |
| Audits or reviews | • No specific external audits or reviews have been undertaken. |

| Mineral tenement and land tenure status |
• The Fraser Range significant intercepts are in one exploration licence as listed below. Joint venture Tenement Expiry IGO (51%) / Classic Minerals (49%) E28/1904 21/10/2021 IGO (51%) / Classic Minerals (49%) E28/2703 11/02/2024 IGO (51%) / Classic Minerals (49%) E28/2704 11/02/2024 IGO (51%) / Classic Minerals (49%) E28/2705 11/02/2024 • At the time of reporting the tenure was secure and there are no know impediments to obtain a licence to operate in future follow up exploration |
|
| Exploration done by other parties |
• There has been historical regional exploration for gold and base metals by the Joint Venture companies listed above. • Previous work on the tenement consisted of aeromagnetic/radiometric and DTM Aeromagnetic / Radiometric / DTM surveys, soil sampling, geological mapping, and ground EM surveys. • There has been previous drilling using reverse circulation percussion (RC) and DD. |
|
| Geology | • The regional geology setting is a high-grade metamorphic terrane in the Albany Fraser belt of Western Australia. • Gabbroic intrusions have intruded a metasedimentary package within the belt are host the nickel-copper-cobalt (Ni-Cu-Co_ mineralisation. • The sulphide mineralisation is interpreted to be related to the intrusive event with mineralisation occurring in several styles including massive, breccia, network texture, blebby and disseminated sulphides. • The main sulphide mineral is pyrrhotite, with nickel and cobalt associated with pentlandite and copper associated with chalcopyrite. • The region is considered by IGO to have the potential to host mafic or ultramafic intrusion related Ni-Cu-Co deposits based on the discovery of the Ni-Cu-Co Nova-Bollinger Deposit and volcanic hosted massive sulphide deposit based on IGO’s Andromeda exploration prospect. |
|
| Drill hole Information |
• The location details of significant intercept holes are tabulated in the body of the ASX Public Report | |
| Data aggregation methods |
• Assay results are pending – grade cutting may be applied once results are received. • Assay results are pending – IGO’s usual practice is to length weight assay results |
|
| Relationship between |
• Only downhole intersection lengths are provided due to the nature of the drilling – any relationships between width and intercept lengths are likely coincidental |

|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• The samples were taken by a RC face sampling hammer drill. All RC holes were sampled at one-metre intervals. • Care was taken to control metre delineation, and loss of fines. • The determination of mineralisation was done via industry standard methods, including RC drilling, followed by splitting, crushing and fire assaying |

• 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). |
• All drilling was completed using reverse circulation method, using a Schramm 645 model rig and 6m Remet Harlsen 4 ½ inch rods. The rig mounted Airtruck has 1150 cfm 500 psi auxiliary couples with a hurricane 7t Booster 2400 cfm /1000 psi booster. The bit size was 5 5/8, |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• Recoveries from the drilling are not known, as sample weights were not recorded at this stage of exploration, but visual inspection of samples in the field indicate that recoveries were sufficient. • The shroud tolerance was monitored, and metre delineation |

Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• Core and chips were logged to a level of detail to support the Mineral Resource estimation. • Logging was qualitative in nature. • All intersections were logged |
| 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. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• The nature and quality of the sampling suits the purpose, being exploration. The laboratory preparation is standard practice and has not been further refined to match the ore. • QC in the lab prep stage was limited to taking pulp duplicates (e.g. no coarse crush duplicates were submitted) • The sample split sizes (4-5 kg are regarded as more than adequate for the nature and type of material sampled. |
| 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. |
• Standard 50g fire assays with an AAS finish were used to get assay results. This is a total technique, and considered appropriate for this level of exploration. • Quality control was carried out by inserting blanks and standards into the sampling chain and 5% intervals. These all showed acceptable levels of accuracy and precision. |

metasediments, BIF’s and cherts to the east of the tenement, overlying an older sequence of metamorphosed komatiitic and high-magnesian basalts to the west. Black shales/pelites occur as small interbedded units throughout the stratigraphy, which dips gently to the east (1035°) and strikes N-S, bending in a NNW direction in the far north of the tenement.
- An Archaean-aged quartz dolerite unit (informally the ‘Wattle Rocks Dolerite’) is emplaced along a contact between high-MgO basalt to the west and low-MgO ultramafic to the east, in the western part of the tenement and is the host rock for the Lady Ada (and Lady Magdalene) mineralisation. Strongly magnetic Proterozoic dolerite dykes crosscut the stratigraphy in an eastwest direction, splaying to the ENE, following fault directions interpreted from the aeromagnetics. A number of narrow shear zones lie subparallel to the shallow-dipping metasediment-mafic contact within the host stratigraphy and are important sites and conduits for the observed mineralisation. The Sapphire shear zone strikes approximately ENE, dipping to the SE at about 25°, and appears to crosscut all lithologies. This shear zone and associated shears host the bulk of the gold mineralisation at Wattle Rocks. Similar flatdipping shears are known to crosscut the Lady Magdalene area. Approximately 8-12 metres of transported sands and a gold depleted weathering profile of saprolitic clays overly the Lady Ada and Lady Magdalene mineralisation.

| • Structurally, the Wattle Rocks area is quite complex and is positioned near the intersection of several major breakages and flexures in the regional stratigraphy in this part of the Forrestania Greenstone belt. Numerous shear zones are evident throughout the area, particularly at changes of rock stratigraphy where there are rheological differences. Narrow, stacked, flat- dipping shear zones are evident within the quartz dolerite unit and may have resulted from thrusting of the younger sedimentary sequence over the mafic package from east to west. A similar model is predicted for Van Uden (10 km northwards) where mineralised quartz veins appear to ‘stack’ through a host ferruginous metasediment. |

| 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. |
• Summary drill hole results as reported in figures and in the appendix 2 to this Report are reported on a 2m internal dilution and 0.5 g/t Au cuto-off. |

| 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’). |
• In almost all cases, the drill holes are perpendicular to the mineralisation. The true width is not expected to deviate much from intersection width. |
| 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. |
• Appropriate images have been provided in the Report. |
| 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. |
• Figures represent specific selected drill intervals to demonstrate the general trend of high grade trends. Cross sections show all relevant result in a balanced way. |
| 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. |
• No other relevant data is reported |
| Further work | • The nature and scale of planned further work(egtests for lateral extensions or |
• Further RC drilling is being considered. |
