First commercial production (post commissioning) started during February 2022 with first copper sales recorded during October 2021. Tons milled for the financial year under review increased by 296% to 67 045 tons compared to the prior period (2021: 16 934t) with copper grade decreasing by 36% from 1.38% to 0.88%. This resulted in copper recovered and sold increasing by 191% to 284.7 metric tons compared to the previous reporting period (2021: 98 Mt). During the financial year under review the operation changed from a filter press to a Fines Optimised Heap Leach (“FOHL”) process during July 2022 to September 2022 to improve both volume throughput and achieve cost reductions in terms of copper leaching. Volume throughput per month increased by 400% from approximately 2 000 milled tons to 10,000 milled tons as a result of the change to the FOHL dams. Copper recoveries however decreased by 14% (2023: 48%) from 56% during the previous reporting period. Despite the decrease in recoveries the resultant increase in volume more than made up for the lower copper recovery. A major impact during the current reporting period was a decrease of 36% in the delivered grade from 1.38% (2023: 0.88%) compared to the previous reporting period. This was the result of the initial high grade (in situ grades of between 1.2% and 1.6% Cu) ore stockpiles at Nababeep (where the processing plant is located) being depleted and only lower grade stockpiles remaining (in situ grades of between 0.6% and 1% Cu). Management in terms of grade flexibility (by having different grade stockpiles for mixing to deliver optimum feed grade) was impacted by the original crushing system not being adequate and having to be replaced by contract screening and crushing. This issue has been resolved with (a) the acquisition post period of a R30 million new crushing plant that will be operated “in- house” and (b) addition of higher-grade stockpiles from the Carolusberg and Jubilee sites (in situ grades varying between 1% and 3.5% Cu). The new crushing plant will have an increased monthly processing capacity of 100 000 tons compared to the current crushing capacity of 30 000 tons per month. This will not only allow for better stockpile management but also cater for the ore that will feed the new floatation processing plant being constructed. Average effective copper price received decreased by 5.44% to ZAR117k/Mt of Copper metal sold (2022: ZAR123k/Mt). Although the LME copper price decreased by 11.16% to USD8 676/Mt compared to the previous period (2022: USD9 766/Mt) the ZAR: USD exchange rate improved during the same comparable period by 7.33% to 16.54 (2022: 15.41). This reduced the impact in terms of the discount to LME price received ex-works by only 0.93% to ZAR26 364 compared to ZAR26 613 received during 2022. The operating loss increased by 279% to ZAR80.7 million compared to the previous period (2022: ZAR21.287 million). Revenue increased by 174% to ZAR33.4 million compared to ZAR12.1 million in 2022. It should however be noted that the previous reporting period included other income related to the sale of revenue sharing royalty agreement of ZAR31.154m. Operating expenses increased by 241.6% during the financial year to R114.1 million compared to ZAR33.4 million during 2022. The increased operating loss was a result of a) Fixed expenses being incurred for 12 months compared to 5 months in the prior period, b) commissioning costs, c) contract crushing, d) plant stoppage as result of the solvent extraction circuit having to be restocked and safety stoppages, e) loadshedding - the operations have been and continue to be hampered by the current load shedding regime. This has effectively resulted in it only being able to operate at 50% of its capacity, principally as a result of diesel generator backup failures due to frequent loadshedding occurrences, and f) the second mill arriving 4 months late due to COVID 19-related logistics bottlenecks and thus impacting on production output. Subsequent to the capital raising accompanying the listing of Copper 360 on 21 April 2023, several investments have been committed to that will address the root causes of operating losses. These include: a) the acquisition of an owned crushing plant that will replace the current crushing contractor. This plant has been ordered and will be installed during June 2023. The plant will also crush the ore feed from the sulphide ore projects that are currently being developed elsewhere in the group, b) further backup generator capacity is currently being installed and it is expected that it will enable CCOC to increase its copper output from July 2023, and c) the introduction of thickeners that will supplant the FOHL process and increase the recoveries from current levels of around 50% to in excess of 80%, which will result in increased copper output. Pursuant to the above, it is expected that the forecast copper production for the financial year ending 29 February 2024 contained in the Pre-listing statement will be achieved.
