29 April 2021 ASX Announcement
MARCH 2021 QUARTERLY ACTIVITIES REPORT
Classic Minerals has made further progress at Kat Gap during the quarter as it strives to become a gold producer.
Highlights of the quarter include:
-
Assay results returned for deeper RC drilling testing potential plunge of high-grade gold mineralisation at Kat Gap;
-
Infill RC drilling results finally returned early in January;
-
Advancing mining studies at Kat Gap, and
-
IGO have made further progress at Classic’s Fraser Range Project.
-
No drilling activities were undertaken during the quarter by the Company.
Assay results were finally received for the large infill and deeper RC drilling programs conducted in the September and December 2020 quarters. These programs were focused on shallow infill drilling of the current inferred JORC resource plus deeper drilling of the potential down plunge of shallow high-grade gold mineralisation.
IGO have continued geophysical work on their newly discovered high conductance discrete EM anomaly over the Thylacine and Sabretooth area (now known as the Moa target) within a broader stratigraphic conductor. The feature has generated a 13,000S plate at 100m depth with dimensions of 210m by 180m.

Infill RC drilling
The 81-hole infill RC drilling program (FKGRC207-228, FKGRC231-245 and FKGRC267-313) covers an area approximately 300m along strike to the north of the Proterozoic dyke (See Figure 3.0). The infill drilling was focused on testing the main granite-greenstone contact lode within the existing inferred resource to an average depth of 75m below surface. The holes have been drilled on 20m x 10m and 10m x 10m grid spacings to bring the near surface parts of the inferred resource to indicated status prior to final pit design work.
Infill drilling has confirmed continuity of mineralised zones within the inferred resource model north of the Proterozoic dyke.
Better results from the infill holes include:
-
1m @ 10.10g/t Au from 54m in FKGRC218
-
4m @ 5.00g/t Au from 35m including 1m @ 11.40g/t Au from 38m in FKGRC222

Deep RC Drilling
Deeper RC holes testing the down plunge potential are all located within 100m north along strike from the cross cutting Proterozoic dyke and form part of the much larger future deeper drilling program (See Figure 3.0). A total of 18 holes for 2,824m (FKGRC320 – 333 and FKGRC 339 – 342) were completed during November and December last year. Interpretation of the recently received assay data has confirmed a northerly plunge of about 55 degrees closely linked to the flattening or rolling of the granite-greenstone contact. The gold is associated with smokey grey quartz veins within weakly sheared granite some 10-15m in from the main granite-greenstone contact. The plunge line is completely open to the north.
Better results from the deeper RC holes include:
-
11m @ 3.63g/t Au from 76m including 1m @ 11.80g/t Au from 83m in FKGRC320
-
5m @ 4.37g/t Au from 121m including 1m @ 13.40g/t Au from 122m in FKGRC321

We have received the following update of progress on the exploration carried out during the March 2021 quarter by IGO on the tenements.
Summary:
Between 15 December 2020 and 15 March 2021, the following exploration activities were completed by IGO within the IGO – Classic Minerals Joint Venture tenements, namely E28/1904, E28/2703, E28/2704 and E28/2705 (Figure 8).
-
Additional sampling of 19AFRD2009 from the IGO 2019 diamond drilling program at the Mammoth Ni-Cu occurrence was undertaken, and while no economically significant assays were returned, further analysis indicated the presence of a gabbronorite intrusion.
-
A MLEM survey was undertaken across the northern extension of the Sabretooth-Thylacine trend.
-
A discrete EM conductor of 13,000S conductivity identified (from here referred to as the Moa target).

Work Completed Sampling
During the Quarter, 60 samples from the diamond drillhole 19AFRD2009 were sampled and sent for analysis. 19AFRD2009 was drilled as part of the IGO 2019 diamond drilling program at the Mammoth Ni-Cu occurrence (Figure ) and did not intersect significant mineralisation. The sampling program was designed to confirm the intrusive lithologies intersected below the Mammoth Ni-Cu occurrence that was not sampled during the initial sampling.
Geophysics
An MLEM survey was completed at the Classic Minerals JV tenements in two campaigns in July 2020 and February 2021, designed to cover the previously identified Sabretooth-Thylacine intrusive trend (Figure ) and associated auger soil nickel and copper anomalism. This is located south of the Mammoth prospect within tenements E28/1904 and E28/2703. The survey was completed by GEM Geophysics using a High-Temperature SQUID (HTS) sensor who used 400m transmitter loops to maximise the depth of investigation. The receiver was placed 400m east of the loop centre in a slingram configuration to avoid unwanted polarisation effects. Figure illustrates the location of the February 2021 relation to the Mammoth prospect, the Sabretooth and Thylacine trend, and the July 2020 MLEM survey.
The area had been previously covered by a VTEM (Versatile Time Domain Electromagnetic) airborne survey flown by Classic in 2013, which showed that the geology is highly resistive along the Ni-Cu anomaly. The resistive nature of the geology means that significant conductors within the top 300m should have been identified by the airborne EM. The objective of the HTS MLEM survey is to screen the area for deep conductors beyond the depth of investigation of the airborne EM and investigate three low order anomalous zones identified in the VTEM survey.

Results
Geophysics
Moving Loop Electromagnetic Survey (MLEM)
-
The survey data was found to be of good quality with noise levels in the order of 0.03 – 0.05 pT/a, which is consistent with expectations for the HTS sensor.
-
The main feature in the MLEM data is the large stratigraphic conductor running along the NW boundary of the survey grid. This was expected from the interpretations of the pre-existing airborne EM data. However, a discrete conductor along this stratigraphic trend has been interpreted based on the presence of a shorter wavelength, late-time, stronger anomaly. Additional data was collected over the response to obtain a better constrained model; the new EM target has been named ‘Moa’.
-
Modelling of the Moa anomaly best fits a 210m x 180m, steeply west-dipping plate of high conductance (~13,000S) starting approximately 100m from the surface (Figure 10). The conductor is coincident with a long NE-trending magnetic unit, which also correlates with the large stratigraphic response observed in both the airborne and ground EM surveys (Figure 11). The Moa anomaly could be explained by one of the following scenarios:
-
A more conductive portion of the stratigraphy caused by local folding, thickening &/or a local primary facies change with a higher carbon &/or sedimentary sulphide content.
-
A detached portion of the stratigraphy brought closer to the surface due to structure.
-
An Andromeda-style metamorphosed volcanic hosted massive sulphide (VHMS) Fe-Cu-Zn occurrence. The Andromeda prospect is ~15km along strike to the NW in a similar stratigraphic position.
-
A localised mafic-ultramafic intrusion-hosted magmatic Fe-Ni-Cu sulphide occurrence.

Diamond Drilling
No diamond drilling (DD) was conducted during the Quarter.
Diamond Drilling Results
All the DD assay results from samples taken from 19AFRD2009 (Mammoth, Figure 12), were received during the Quarter. While no economically significant assays were returned, sampling does indicate the presence of a gabbronorite intrusion, which is shown in the downhole geochemical plots in Figure 14.

| HOLE ID | EAST | NORTH | RL | DEPTH | TENEMENT | PROSPECT |
|---|---|---|---|---|---|---|
| 19AFRD2009 | 553682.8 | 653120 | 233.632 | 429.5 | E28/1904 | Mammoth |
Two mafic units have been identified within the drillhole. The upper unit appears to be primarily a mafic granulite of noritic composition. The lower unit, from 230m-248.26m downhole, is interpreted to be a gabbronorite. Minor poly-phase sulphides were intersected within this gabbronorite with one interval returning of 0.41m @ 1,110ppm Ni and 182ppm Cu from 232.36m.

This unit lies directly down-dip from the previously intersected Mammoth mineralisation, which is now interpreted as being primarily hosted within, and/or close to this gabbronorite unit. Two other narrow mafic intrusions were also seen within the hole. (Figure 13)

Wood blocks with missing intervals are typically inserted into the boxes • • For recovery checking and orientation marking purposes, the DD core was reconstructed 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 • 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. • |
| Sub-sampling techniques and sample preparation |
• • The DD core was generally subsampled into 0.5-1 metre half-core using 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 nature of the drilling method means representation is indicative with sampling aimed at finding anomalous concentrations • The ALS laboratory sample is by oven drying (12 hours at 100°C), 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 of 85% passing 75m and collection of a 300g sub-sample. 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 were used to determine any element concentrations. − • ALS laboratory completed sample preparation checks for particle size distribution compliance as part of routine internal quality procedures to ensure the target particle size distribution of 85% passing 75 µmis achieved in the pulverisation stage. • Laboratory quality control processes include the use of internal lab standards using certified reference materials (CRMs) and duplicates. • CRMs used to monitor accuracy have expected values ranging from low to high grade, and the CRMs were inserted randomly into the routine sample stream to the laboratory. Cu, Co, Cr, MgO, Ni, SiO2, and Zn were consistently cecked for accuracy. • The results of the CRMs confirm that the laboratory sample assay values have good accuracy and results of blank assays indicate that any potential sample cross contamination has been minimised. • CRMs and blanks were routinely inserted at frequencies between 1:10 and 1:20 samples for DD sample streams. • DD samples were 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, |

| Verification of sampling and assaying |
• Assay data are imported directly from digital assay files from ALS and are merged into IGO’s acQuire/SQL database by IGO’s Geological Database Administrator. • All digital data is backed up regularly in off-site secure servers. • No portable XRF results are used in exploration results reported. • There have been no adjustments to the assay data. |
| Location of data points | • Drill path gyroscopic surveys were completed at either 10m or 12m intervals down hole using a north seeking REFLEX GYRO SPRINT-IQ for DD holes. • • The grid system is GDA94/MGA Zone 51. |
| 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. • All samples have been composited using length-weighted intervals for Public Reporting. |
| 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 from both the southeast and northwest to provide stratigraphic coverage. • |
| 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 Nova by IGO staff and contractors • e. • • 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. |
