West Wits Mining Unveils Enhanced Economics in Updated Qala Shallows DFS
Upgraded Study Shows 97% Increase in NPV and 81% IRR for South African Gold Project
West Wits Mining (ASX: WWI, OTCQB: WMWWF) has announced significant improvements in the economics of its Qala Shallows gold project, part of the larger Witwatersrand Basin Project (WBP) in South Africa. The updated Definitive Feasibility Study (DFS) reveals substantially enhanced project economics, driven by higher gold prices and optimized mining plans.
The revised study shows a 97% increase in post-tax NPV to US$500 million and a post-tax IRR of 81%, up from 53% in the 2023 DFS. These impressive figures are supported by a 58% increase in projected revenue to US$2.7 billion and an 88% increase in free cash flow to US$983 million.
"The updated DFS for Qala Shallows has delivered a compelling outcome, reinforcing the project's robust value and strong economic fundamentals," said West Wits Mining Managing Director Rudi Deysel. "Notably, the peak funding requirement and payback period have reduced, while Free Cash Flow has surged by US$461 million — an 88% uplift — bringing total projected Free Cash Flow to US$983 million."
Key Highlights of the Updated DFS
The updated feasibility study includes several significant improvements compared to the 2023 DFS:
| Metric | 2023 DFS | 2025 Updated DFS | Change |
|---|---|---|---|
| Post-tax NPV7.5 | US$255M | US$500M | +97% |
| Post-tax IRR | 53% | 81% | +53% |
| Total Revenue | US$1.7B | US$2.7B | +58% |
| Free Cash Flow | US$522M | US$983M | +88% |
| Peak Funding | US$54M | US$44M | -18% |
| Payback Period (from peak funding) | 13 months | 8 months | -38% |
| Ore Reserves | 351,423 oz | 383,934 oz | +9.3% |
The improved economics are largely driven by:
- Higher gold price assumptions of US$2,850/oz compared to US$1,850/oz in the 2023 study
- Lower cut-off grade of 1.31g/t (down from 2.0g/t), allowing for inclusion of additional ore
- Compressed mine life from 17.7 to 16.8 years, improving project economics
- Extended steady-state production of 70,000oz per annum from 9 to 12 years
- Increased Ore Reserves by 9.3% to 383,934 oz gold at 2.60g/t
Understanding Cut-Off Grade: Why It Matters to Investors
For investors new to mining economics, the cut-off grade is a critical concept that directly impacts a project's economics. The cut-off grade is the minimum grade of mineralised material that can be economically mined and processed, based on current metal prices and operating costs.
In West Wits Mining's case, the higher gold price environment has allowed the company to reduce the cut-off grade from 2.0g/t to 1.31g/t. This means previously uneconomic material can now be included in the mine plan, effectively increasing the mineable resource without additional exploration costs.
This adjustment has significant implications:
- More ounces in the mine plan – increasing total production and revenue
- Higher initial production – improving early cash flows and reducing payback period
- Extended mine life – providing longer-term value for shareholders
Project Funding and Development Progress
In June 2025, West Wits Mining secured financing through a syndicated loan facility of up to ZAR 875 million (~US$50 million) jointly provided by the Industrial Development Corporation of South Africa Limited and Absa Bank. This funding will cover the US$44 million peak funding requirement identified in the updated DFS.
The company has already made significant progress at Qala Shallows, with the first Load-Haul-Dump (LHD) unit delivered to site, marking the commencement of mobilisation. Key infrastructure components completed include:
- Substations and water infrastructure
- Decline and box cut rehabilitation
- Underground access to the reef
- Initial ore production during the Early Works Program
Investment Thesis: Why West Wits Mining Stands Out
West Wits Mining presents a compelling investment case even in more conservative gold price scenarios. Sensitivity analysis shows that at a US$1,850/oz gold price (the base case in the 2023 DFS), the project still delivers strong returns with a post-tax NPV7.5 of US$194 million and a post-tax IRR of 35%.
The project demonstrates remarkable resilience across various gold price scenarios:
| Gold Price (USD/oz) | Post-Tax NPV7.5 (USD'm) | Post-Tax IRR (%) | Operating Margin (%) | Payback Period (years) |
|---|---|---|---|---|
| 1,850 | 194 | 35 | 46 | 4.9 |
| 2,350 | 345 | 57 | 56 | 3.9 |
| 2,850 | 500 | 81 | 63 | 3.3 |
| 3,350 | 652 | 103 | 67 | 3.0 |
| 3,850 | 805 | 128 | 71 | 2.8 |
This scalability of returns positions West Wits Mining to capitalise on the current strong gold price environment while providing significant downside protection.
Next Steps and Upcoming Catalysts
The company has outlined clear next steps that should provide regular news flow and potential catalysts:
- Securing the balance of project funding
- Continuing equipment purchases and contractor mobilisation
- Building a 30,000-tonne gold ore stockpile for consistent processing
- Gradual mine build-up toward steady-state production of 5,700 ounces per month
Why Investors Should Follow West Wits Mining
West Wits Mining gold project updates offer investors exposure to a gold project with robust economics that has now reached the development stage. Key reasons to track this stock include:
- Near-term production with just 3.3 years from development start to payback
- Extremely strong project economics with 81% IRR and $500M NPV
- Low funding requirement of just US$44M with financing already secured
- Significant upside from current gold prices above US$3,300/oz
- Established mining jurisdiction in South Africa's world-famous Witwatersrand Basin
- Experienced management team with proven mining expertise
With the updated DFS demonstrating enhanced economics and development activities already underway, West Wits Mining is positioned to capitalise on the strong gold market while establishing itself as a significant gold producer in the historic Witwatersrand Basin.
For investors seeking diversification, Marvel Gold's Hanang gold project in Tanzania represents another compelling investment opportunity in the African gold sector. Additionally, the Australian gold market continues to show promise with Austin Metals beginning drilling at a high-potential gold target near top producers.
The gold sector has seen several notable developments recently, including Hammer Metals unveiling two major gold-copper discoveries in North Queensland. Furthermore, Carnaby Resources' Trekelano copper-gold expansion highlights the growing interest in polymetallic projects with gold components.
Investors looking for district-scale potential might also consider Enmore's significant gold discovery which shows considerable exploration upside in a promising geological setting.
