Only providing these links for info, no comment other than time and circumstance required the plans to be changed. I do think that they overestimated the quality of the equipment and underestimated the investment required though.;

Vametco Diagnostic Review
· Vametco's 2018 production of 2,560mtV was impacted by a total of 37.5 days stoppages and unexpected operational challenges. An estimated 230 mtV of production was lost due to these unforeseen events. The total potential production for the year would therefore have been approximately 2,800 mtV. Following the operational challenges experienced during the ramp up of Phase 2, Bushveld Minerals, with the assistance of an external consultant, commenced in October 2018 a detailed diagnostic review of the Vametco plant performance which was completed in December 2018. The primary findings of the diagnostic assessment are summarised below.
Phase 2 of the multi-phase project
Ø Phase 2 of the multi-phase project was completed in June 2018 increasing production capacity to 3,750 mtV. During the commissioning phase, production of the new milling circuit was unable to ramp up to the nameplate capacity. Concurrently, there was a reduction in the run-of-mine ore vanadium grades. These events lead to a reduced concentrate production, lower recoveries and plant instability, resulting in the plant not meeting its capacity target.
Ø The diagnostic review highlighted that no additional capital expenditure is required to achieve a sustainable production of c.3,400 mtV, which represents 90 per cent of the name plate capacity. In order to achieve the production target management will be primarily focused on, among others:
§ Increasing vanadium grade in crushed ore through improved mine scheduling which will result in an increased exposure to ore of higher vanadium content and magnetite;
§ Increasing vanadium grade in kiln feed through improved silica liberation;
§ Increasing kiln availability through improved engineering practices and production throughput; and
§ Sustainably increasing the kiln feed rate.
Phase 3 of the multi-phase project
Ø The diagnostic assessment highlighted that additional targeted investment is required for the kiln, the leach and crushing circuits to reach Phase 3 capacity. The Company continues to explore several improvement initiatives to further increase production capacity to 5,000 mtV.
§ During 2019 Vametco will continue to progress environmental approvals for Phase 3 of the multi-phased expansion project. In addition, detailed design work and capital estimation will commence with a view to construction commencing in 2020.
