    Witwatersrand Basin Project, South Africa

    Quick overview

    The WBP is set to transform West Wits into a long-term gold producer, with average steady state annual ROM production of 65,000oz for 25-years, over a 27-year LOM for 1.6Moz of gold.

    Qala Shallows is stage one of fourstages at the WBP. The Qala Shallows Definitive Feasibility Study supports an underground mining operation with a robust rate of 7.3MT at 2.81g/t recovered grade for 663,000 oz recovered Gold over a 17-year Life-of-Mine.

    Ground operations commenced at Qala Shallows in September 2021, with bush clearing, site preparation and underground technical surveys. Early works were implemented over a six-month period from October 2021 to March 2022, with first production achieved in February 2022. The early works successfully delivered surface infrastructure and refurbishment of historical underground workings.


    Background

    West Wits received formal communication from South Africa’s Director-General of the Department of Mineral Resources and Energy on 19th July 2021 that the Company’s mining right application was granted in terms of section 23(1) of the Mineral and Petroleum Resources Development Act, 2002 (Act 28 of 2002). The Department’s decision to grant West Wits’ mining right is a pivotal milestone that heralded in the development of the WBP.

    An independent scoping study was carried out by the highly regarded South African mining services firm, Bara Consulting, with results received in July 2020. The study confirmed the Company’s view that WBP offers multiple areas for mining, identifying five distinct areas which enable staged development.

    The CAPEX profile to recommence mining is expected to be low due to the existing historical infrastructure and planned toll treatment.

    A key objective of the independent scoping study was to provide an assessment of the mining potential over the whole project area. The study confirmed the project’s distinct positive investment parameters which de-risks the project.


    Scoping Study and Production Target

    The updated Scoping Study results announced in March 2022 firmly established the WBP’s potential to progress into a long-term gold mine. The results outlined an average steady-state annual production of +65,000oz with a 27-year Life-of-Mine. The results also indicated that WBP has the potential to build up to a peak production rate of 90,000 oz per annum. The Scoping Report outlined a production target which averages 76,500oz per annum from Years 5 – 16, with 92,000oz achieved in Year 6.

    Four distinct mine stages were identified for the project:

    1. Qala Shallows
    2. Main Reef Package
    3. Bird Reef East
    4. Qala Deeps

    Bird Reef Central is subject to an updated Uranium Exploration Target providing the potential opportunity to become a standalone gold and uranium project.


    Four distinct mine stages were identified for the project:

    1: Qala Sallows
    2: Main Reef
    3: Bird Reef East
    4: Qala Deeps

    Stage 1 Qala Shallows Definitive Feasibility Study
    and Early Mining Initiative

    Qala Shallows provides the backbone to underpin subsequent stages of production over a long life of mine. Additionally, the combination of the existing infrastructure (Qala Adit) and accessible shallow Mineral Resources allow access for production on a fast-tracked timeframe relative to most global opportunities for underground gold mining.

    First ore was extracted in Feb 2022, building up to an annualised production rate of 25,000 oz Au per annum after 30 months and reaching a full steady-state production rate of 53,000 oz Au per annum after year four.

    West Wits commenced early works at Qala Shallows in September 2021. Information gathered on underground inspections confirmed that there was sufficient ROM remnant material left over from the old mining operations to kick-start the initiative. Early works were implemented over a six-month period from October 2021 to March 2022. with first production achieved in February 2022. The early works successfully delivered surface infrastructure and refurbishment of historical underground workings.

    West Wits has commenced a new initiative, Project 200, which aims to increase production at the WBP to 200,000oz per annum by increasing the Qala Adits throughput capacity. Stage 1 is well-advanced with the completion of the Qala Shallows DFS and commencement of the early works which aims to achieve early cash flow from estimated production of 5,000 – 8,500t ore per month from April 2022. This will provide an excellent production springboard as we ramp up Qala Shallows production and advance Stage 2 and 3 feasibilities.


    Uranium Exploration

    During 2008, West Wits completed and reported results of a first pass Uranium Exploration Program at the WBP. We are now recommencing investigations into the prospectivity of the uranium-bearing reefs within the Bird Reef Central area.

    The aim is to convert a JORC 2012 compliant exploration target of 12-16mlbs into a resource. Drilling will commence in the second half of 2022.


    Resource Statement

    Current Global Mineral Resource Estimate for the WBP

    The current global MRE for the WBP was released to the ASX in December 2021. West Wits has 4.28 million ounces at 4.58 g/t JORC Mineral Resource Estimate (MRE). The Company’s development strategy aims to produce 60,000oz Au per annum over 20-year plus Life-of-Mine with first production by early 2022.

    West Wits’ MRE is derived from the historic DRD resource, but only includes ounces to a 1,500m depth from surface and does not include deep underground material previously considered in the DRD estimation. The chosen headline cut-off grade of 2 g/t is based on historic figures and should ensure that the bulk of the resources can be reasonably expected to be exploited.

    West Wits is not aware of any new information or data that materially affects the MRE information and confirms that all material assumptions and technical parameters underpinning the estimates above continue to apply and have not materially changed. The Global MRE set at a 2.0 g/t Au cut-off, reported in accordance with the JORC Code of 2012. Number differences may occur due to rounding errors. (ASX Announcement 23 July 2021.)

    Additionally, the ore bodies are still open in multiple directions with additional reef packages of the prolific Witwatersrand Basin system yet to be explored by West Wits in the project area.
