At Mindola the Kitwe Formation is the major host to Cu-Co (copper-cobalt) mineralisation at Nkana-Mindola, particularly within the Ore Shale member. The Ore Shale has been subdivided into multiple units based on texture and composition. In summary, a black shale or dolomitic siltstone. often with a schistose or banded texture, passes upwards into a coarser porous sandstone or siliceous dolomite and capped by a massive argillite. Mineralisation across Nkana-Mindola is primarily hosted by dolomitic siltstones, pyritic black shales and schists. At Nchanga samples were analysed from the upper and lower ore bodies hosted within the Lower Roan metasediments which unconformably overlie the basement, transitioning from basal continental, arenaceous clastic rocks to shallow marine argillaceous clastic rocks and mixed platform carbonates.

A suite of 40 elements were acquired for rutile and 47 elements for apatite. Rutile and apatite grains were located using TESCAN TIMA maps imported into the Chromium 3.1 software. Ablation was performed using a fluence of 3.5 J/cm2 repetition rate of 5 Hz. Background signal was measured for 30s followed by 30s of acquisition time. A 20 µm spot size was used for rutile and 25 µm for apatite dictated by the grain sizes in the samples. Stoichiometric values for Ti47 (59.95 wt.%) and Ca43 (38.5 wt.%) were used as internal standards for rutile and apatite, respectively. Mass spectrometer calibration was conducted using the NIST610 glass standard for rutile and NIST612 for apatite (Jochum et al., 2011). Reference materials BCR-2G and GSD-1G were analysed as secondary standards to evaluate the reproducibility of the data. Literature values used for each glass standard were downloaded from the GEOREM database (Jochum et al., 2011). Rutile mineral references materials R10b, R13 (Luvizotto et al., 2009a) and R632 (Axelsson et al., 2018) and the Durango apatite standard (Chew et al., 2016) were run as unknowns to monitor accuracy and precision. Standard-sample bracketing using these reference materials was performed after ~10 unknown analyses. Data processing and reduction was performed using an offline Microsoft Excel VBA spreadsheet. Signals containing mineral inclusions, notable contamination or low signal-noise ratio were omitted from the final spreadsheet.
