Firm A operates two distinct supply chains from its mining
facilities. One supply chain originates with the extraction of
raw materials from its mine in the Northern Cape, which
are processed into a semi-finished industrial product. The
coal that is required for this process is sourced from a coalmining
supplier. Once the semi-finished product has been
processed, it gets packaged and is sent directly to customers.
This supply chain is depicted in Figure 1.
