ASX ANNOUNCEMENT 27 JANUARY 2022
GULF COPPER-GOLD PROJECT: DRILLING UPDATE
Proof-of-concept drill tests on two magnetic targets have been completed on the Gibson's Tank tenement in Northwest Queensland (Figure 1).
Drill hole GTK2101 on the combined high magnetic and high gravity target GT07 intersected a 44.4 metre interval from 486.6 metres of hydrothermal ironstone and breccia within a deformed felsic volcanic sequence that defines the source to the geophysical target. The ironstone contains weakly disseminated copper sulphides that returned low copper assay values ranging from 0.008% to 0.34% and very low gold values ranging 0.002g/t to 0.013g/t.
Drill hole GTK2102 on the high magnetic but weak gravity target GT4 intersected a felsic to intermediate intrusive rock altered by veinlet networks of chlorite and magnetite that appears to explain the source to the geophysical anomaly. No significant intervals of copper or gold mineralisation were encountered in this hole.

Mr Rutherford is the Managing Director of the Company. Mr Rutherford has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" (the JORC Code).

Sampling Techniques
Nature and quality of sampling
Include reference to measures taken to ensure representativity samples and the appropriate calibration of any measurement tools or systems used.
Aspects of the determination of mineralisation that are Material to the Public Report.
GTK2101 and GTK2102 rotary/mud diamond core holes designed to test the source of the regionally significant high magnetic and gravity anomalies. GTK2101 comprises rotary mud chips to 486.6 metres and NQ2 diamond drill core to the end of hole at 932m. GTK2102 comprises rotary mud chips to 640.4 metres, HQ diamond core to
737.5 metres and NQ2 diamond drill core to the end of hole at 963.8m. The method of drilling is considered to be of an acceptable quality for evaluating the source of a geophysical target and reporting of exploration results. Sampling for geochemical analysis was selective and is not continuous down the whole length of the core. A one metre length of half core was regularly sampled about every 4 to 10 metres down the hole with one metre spaced half core samples collected over localised intervals of mineralisation or geological interest.
Magnetic susceptibility values were measured using a hand-held KT9 susceptibility metre which utilises an air calibration to zero the instrument prior to taking a measurement. Samples for geochemical analyses were collected every metre through massive ironstone and visible sulphide-mineralised in GTK2101. Unmineralised drill core in GTK2101 was sampled every 4m locally increasing to 10m while unmineralised core in GTK2101 was sampled every 10m.
Visual results of the geology and mineralisation were observed by an experienced senior geologist and checked by the Exploration Manager of Red Metal. Weak copper mineralisation and anomalous trace elements were confirmed with assays.

etc.). |

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.
The length of recovered core and the core rock quality are logged for each core run. Core recovery throughout the fresh basement rocks is very good (90-100%). Minor intervals of poor core recovery (<30%) occur in, localised, 1-2m wide chloritic fault zones.
Diamond core is reconstructed into continuous runs on an angle iron cradle and marked with orientation lines. Depths are checked against depths marked on the core blocks and rod counts are routinely performed by the drillers.
No bias expected as very good core recovery
For
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.
Whether logging is qualitative or quantitative in nature.
Core photography
The total length and percentage of the relevant intersections logged.
Quantitative geotechnical logging including RQD and core recovery are measured for each core run.
Qualitative and quantitative codes and descriptions are used to record geological data such as lithology, mineralisation and alteration prior to sampling. Quantitative structural data is also measured prior to sampling. Magnetic susceptibility is quantified for the total length of the core with measurements taken every 0.5m and averaged over every core run (3 to 6 metres). Specific gravity is quantified using the Archimedes Method at varying intervals down the holes based on the geology. A total of 90 specific gravity measurements were collected in GTK2101 and 28 in GTK2102.
Core is photographed wet and dry.
The total lengths of GTK2101 and GTK2102 have been geologically logged. RDQ and magnetic susceptibility and specific gravity have been measured for the total length of the core.

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 (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
All 182 samples were assayed by ALS with 10 samples analysed for whole rock lithogeochemistry by Li-borate fusion (total digest) ICP-OES and ICP-MS finishes (method CCP-PKG01) including total C (C-IR07) and total S (S-IR08) with the remainder by four-acid (near total) digest with ICP-MS finishes that includes REE (method ME-MS61r). All samples were assayed Au by fire assay (30g) with AAS finish (method Au-AA23). No geophysical tools were used to determine element concentrations at Gibsons Tank
Blanks and certified reference material were inserted and represented approximately 2.2% of samples assayed. Results and internal lab QC indicate acceptable levels of accuracy.
Verification of sampling and assaying
The verification of significant intersections Result reviewed by senior geologist and the Managing Director by either independent or alternative
company personnel.

The use of twinned holes.
Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
No holes have been twinned
Primary data is stored both in its source electronic form, and, where applicable, on paper. Assay data is retained in both the original certificate (.pdf) form, where available, and the text files received from the laboratory. Primary data was entered in the field into a portable logging device using standard drop-down codes. Text data files are exported and stored in an Access database. MapInfo software is used to check and validate drill-hole data.
