Name of the Project
Witwatersrand basin project (WBP) – Qala Shallows Phase 1.
Location
At the northern edge of the Witwatersrand basin, in the Central Rand Goldfield, immediately south-west of the City of Johannesburg, in Gauteng, South Africa.
Project Owner/s
West Wits Mining.
Project Description
The Qala Shallows Phase 1 project forms part of West Wits’ WBP and covers a 60% subsection of the WBP scoping study.
Phase 1 has a declared ore reserve of 3.2-million tonnes grading 2.81 g/t, and total mineral resources estimated at 29.05-million tonnes grading 4.58 g/t gold.
Total production is estimated at 680 000 oz of gold over a 15.7-year life-of-mine (LoM).
Steady-state production is estimated at 55 000 oz/y for ten years.
Phase 2, or Project 200, aims to substantially increase production to 200 000 oz/y of gold. A scoping study is scheduled for 2023 to determine additional infrastructure capital expenditure. Additional infrastructure includes process and tailings storage facilities, shafts and access points.

Latest Developments
West Wits Mining has reported cost savings at its Qala Shallows gold project, after gaining approval for 7.5 MVA of grid power for the project.
The company has said that the use of power from South Africa’s Joburg City Power would lead to significant cost savings – about 75% less expensive, compared to using diesel generators.
Diesel-powered generators will, however, remain an integral part of Qala Shallows’ power supply system, ensuring uninterrupted production during loadshedding and other outages.
West Wits has engaged with renewable-energy suppliers to further reduce the reliance on diesel and mitigate the impact of higher electricity costs; this will ultimately enable the operation to achieve power security at the lowest power cost possible.
Key Contracts, Suppliers and Consultants
Modi Mining (mining contract); and Bara Consulting (LoM production profile).
