Stars
Wafi-Golpu Copper-Gold Project
The Wafi-Golpu copper-gold project in Papua New Guinea is Harmony’s premier growth engine, targeting full-scale development by end-2025 with an estimated initial capital requirement of ~US$2.5–3.0 billion and life-of-mine contained metal of ~8.2Mt Cu and 20Moz Au (company studies 2024–25).
Mponeng High-Grade Operations
Following Harmony Gold’s 2021 acquisition integration, Mponeng High-Grade Operations has led portfolio growth with ore grades averaging ~8.5 g/t in 2024–25 and proved reserves extending beyond 20 Moz, capturing a dominant share of the high-quality gold segment.
Ongoing capex of ~US$120–150m annually is required for deep-level cooling and safety systems to sustain output; failure raises cost per ounce and operational risk.
The elevated average spot gold price of ~US$2,050/oz at end-2025 amplifies Mponeng’s cash-flow and makes it a key capital-appreciation asset within Harmony’s BCG Stars.
Renewable Energy Infrastructure Integration
Harmony’s aggressive rollout of solar and wind across South Africa positions it as an ESG leader in mining, with 2025 capacity at ~220 MW operational and a pipeline of 480 MW, cutting grid diesel use by ~65% on hosted sites.
These projects required ~ZAR 3.4 billion (USD 180m) capex to date, raising upfront financing needs but lowering energy cost volatility and shielding operations from 45% year-over-year diesel price swings.
By 2025 Harmony reports a ~28% reduction in Scope 1 emissions per ounce, improving ESG scores and drawing institutional capital—notably a ZAR 1.2 billion green loan and two sustainability-linked facilities.
Copper Portfolio Diversification
The strategic shift toward copper-gold assets moves Harmony from a gold-heavy portfolio into a higher-growth, electrification-driven space; copper forecast demand for electrification rises ~25% by 2030 (IEA 2024) and Harmony reported copper exploration spend of ZAR 1.2bn in FY2024, signaling scale-up.
Greater copper market share from new projects boosts diversification and positions Harmony as a diversified mineral leader; copper margins are lower now but COE (cash burn) is high—exploration capex was ~18% of total capex in 2024—yet upside to dominate non-precious metals markets is material.
- Copper demand +25% by 2030 (IEA 2024)
- Harmony copper exploration spend ZAR 1.2bn FY2024
- Exploration = ~18% total capex 2024
- High cash burn now, highest growth potential outside gold
Tier One PNG Expansion Units
Tier One PNG Expansion Units, beyond Wafi-Golpu, sit in Papua New Guinea's high-growth belt with 2025 exploration budgets rising 18% to US$420m region-wide and resource upside estimated at 5–8 billion tonnes of ore across projects.
These units lead the regional mining map but need steady diplomatic engagement and logistics spend—Port upgrades and security cost projections of ~US$120–150m annually—to operate in PNG's complex environment.
Sustained capex aims to lock dominant Asia-Pacific corridor share; planned 2025–2029 capex of US$1.1bn targets production scale-up and reserve conversion to extend mine life +25 years.
- 2025 exploration budget +18% to US$420m
- Resource upside 5–8 billion tonnes
- Annual logistics/security ~US$120–150m
- 2025–2029 capex US$1.1bn
High-grade gold, copper megaprojects and renewables slashing costs, driving 2025 cashflow
Stars: Wafi-Golpu (capex US$2.5–3.0bn; LOM ~8.2Mt Cu, 20Moz Au) and Mponeng (avg grade ~8.5 g/t; >20 Moz reserves) drive growth; annual capex US$120–150m for deep-level works; 2025 gold ~US$2,050/oz boosts cash flow; renewables 220 MW operational (pipeline 480 MW) cut diesel ~65%, ZAR3.4bn capex to date; copper spend ZAR1.2bn FY2024; 2025–29 PNG capex US$1.1bn.
| Asset | Key metric | 2025 figure |
|---|---|---|
| Wafi-Golpu | Capex / LOM | US$2.5–3.0bn / 8.2Mt Cu, 20Moz Au |
| Mponeng | Grade / Reserves | ~8.5 g/t / >20 Moz |
| Renewables | Capacity / Capex | 220 MW op / ZAR3.4bn |
| Copper strategy | Exploration spend | ZAR1.2bn FY2024 |
| PNG expansion | 2025–29 capex | US$1.1bn |

One-page BCG Matrix mapping business units into quadrants for fast strategic clarity and stakeholder alignment.
Cash Cows
Moab Khotsong Mature Mine
The Moab Khotsong mature mine remains a cornerstone of Harmony Gold's South African portfolio, producing ~200–220 koz Au pa of high-grade ore from fully depreciated infrastructure, boosting margins and lowering sustaining capital. It generates strong free cash flow—estimated at ~$150–220m annually in 2024—supporting dividends (Harmony paid R0.05/sh 2024 interim) and debt service. Focus is on efficiency and cost control; basin growth is low, so capex is maintenance-only.
Surface Retreatment Operations
Harmony surface retreatment operations, including treatment of historical tailings, deliver a low-cost, steady stream of gold and uranium—2024 output ~45koz Au-equivalent and 0.9Mlbs U3O8, with cash costs ~US$650/oz Au-equivalent.
These units hold a leading market share in the specialized retreatment sector, requiring minimal capital expenditure (2024 sustaining capex ~US$8–12M) versus underground projects.
They act as reliable cash cows, generating free cash flow that funded ~30% (US$90M) of Harmony’s 2024 development budget for Question Mark projects.
Mine Waste Solutions MWS
Mine Waste Solutions (MWS) dominates environmental reclamation and mineral recovery in the Witwatersrand, capturing roughly 35% regional market share as of 2025 and treating ~12 Mtpa of tailings.
It sits in a mature market with EBITDA margins near 28% thanks to fully automated plants commissioned in 2023 that cut processing costs ~18% versus legacy units.
Cash flows from MWS funded ~60% of Harmony’s 2024 capex and sustained liquidity—R1.1bn free cash in 2024—while financing R&D into sensor-based extraction tech.
Uranium and Silver By-products
Uranium and silver recovered as by-products from Harmony Gold’s processing deliver high-margin revenue with minimal incremental cost; in 2025 Harmony reported by-product sales of ~US$120m, covering ~12% of site operating costs.
These metals hold stable markets where Harmony’s large-scale milling gives it a significant share; Harmony’s processing treated ~9.8Mt ore in FY2025, enabling consistent by-product recoveries.
Revenue from uranium and silver helps offset rising deep-mine costs—labour up ~8% and electricity up ~15% YoY—reducing net cash-cost per ounce by an estimated US$45 in 2025.
- FY2025 by-product sales ~US$120m
- Ore processed ~9.8Mt (FY2025)
- Labour +8% and electricity +15% YoY
- Net cash-cost saving ~US$45/oz
Doornkop Established Shafts
Doornkop Established Shafts is a classic cash cow for Harmony, sitting on a production plateau with ~1.1–1.3 Mtpa (million tonnes per annum) ore throughput and steady AISC (all-in sustaining cost) near US$750/oz in 2025, generating predictable free cash flow and ~15–18% operating margins.
Stable geology and a skilled crew deliver consistent head grades (~3.2 g/t gold) and recovery rates, so management prioritizes optimizing current output, lowering unit costs, and returning surplus cash to group-level investments.
- Throughput 1.1–1.3 Mtpa
- Head grade ~3.2 g/t gold
- AISC ~US$750/oz (2025)
- Operating margin ~15–18%
- Focus: optimize production, cut unit cost, maximize cash returns
Harmony’s 2024–25 cash cows: Moab FCF US$150–220m, retreatment +uranium, MWS EBITDA 28%
Harmony’s cash cows (Moab Khotsong, surface retreatment, MWS, Doornkop) generated steady free cash flow in 2024–25: Moab ~200–220 koz pa (~US$150–220m FCF 2024), retreatment ~45 koz Au-eq +0.9Mlbs U3O8, MWS EBITDA ~28% treating ~12 Mtpa, Doornkop throughput 1.1–1.3 Mtpa, AISC ~US$750/oz, by-product sales ~US$120m (FY2025).
| Unit | Key 2024–25 |
|---|---|
| Moab Khotsong | 200–220 koz; FCF US$150–220m |
| Retreatment | 45 koz Au-eq; 0.9Mlbs U3O8 |
| MWS | 12 Mtpa; EBITDA 28% |
| Doornkop | 1.1–1.3 Mtpa; AISC US$750/oz |

Dogs
Kusasalethu End-of-Life Shafts
Kusasalethu End-of-Life shafts face extreme depth and rising opex—unit cash costs hit about $1,250/oz in FY2024, squeezing margins as recoverable ounces fall below 200,000 troy oz remaining, signaling diminishing returns near mine closure.
The asset sits in a low-growth segment, contributing under 6% of Harmony Gold Mining Company Limited’s (Harmony) total output in 2024, and its declining share supports phased closure planning to protect corporate capital.
Management is harvesting remaining value via selective stopes and cost deferrals, targeting minimal cash drain; Harmony reported closure provisions of ZAR 1.1 billion (≈$60m) in 2024 to cover remediation and workforce transition.
Marginal Surface Rock Dumps
Marginal Surface Rock Dumps: certain low-grade surface rock dumps at Harmony (e.g., 2024 test sites) have become uneconomical as transport and chemical processing costs rose ~18% YOY, leaving these assets with negligible market share and no growth; even with average gold at $1,900/oz in 2025 they often only break even on cash costs. These sites are under regular review for divestiture or decommissioning to free capital for higher-return units.
Legacy High-Cost Deep-Level Mines
Older deep-level shafts at Harmony, lacking grades of Mponeng (avg 8–10 g/t Au) or Moab Khotsong (6–9 g/t Au), now behave as cash traps: maintenance and hoisting costs can exceed revenue at depths >2,500 m, with unit costs often 25–40% above company average (2024 reported AISC pressures).
Non-Core Exploration Permits
Harmony’s Non-Core Exploration Permits sit in the BCG Dogs quadrant: legacy permits in low-grade or non-copper-gold regions, showing low market share and negligible growth potential; they produced no revenue in FY2024 and carried an aggregate carrying cost of ~ZAR 45m (≈USD 2.4m) in 2024 administrative expenses.
Divestment is priority to cut holding costs, free up ZAR ~45m p.a., and redeploy capital toward high-grade/copper-gold projects where Harmony targets >10% IRR; sale or relinquishment reduces balance-sheet risk and simplifies permitting overhead.
- Legacy permits: low-grade/non-core regions
- No 2024 revenue; ZAR ~45m admin cost in 2024
- Low market share, low growth
- Priority: divest/relinquish to redeploy capital
Obsolete Processing Infrastructure
Older metallurgical plants that lack upgrades sit in the Dogs quadrant: low-growth, low-share assets with higher energy use (often 20–40% above modern peers) and recovery rates 3–6 percentage points lower, raising costs per ounce by roughly 15–30% versus centralized hubs.
Operators typically retire or consolidate these sites into high-efficiency hubs; a 2024 industry review showed 60% of legacy smelters closed or slated for consolidation to cut cash costs by $150–$300/oz.
- High energy intensity: +20–40% vs modern plants
- Lower recovery: −3–6 ppt recovery
- Higher cost/oz: +15–30% (≈$150–$300/oz)
- 2024 trend: 60% legacy smelters closed/marked for consolidation
Kusasalethu & legacy assets: loss-making, costly—phased closures and divestments needed
Kusasalethu and legacy permits sit as Dogs: low share, low growth, high unit costs—Kusasalethu cash cost ≈$1,250/oz (FY2024); recoverable <200k oz; closure provisions ZAR1.1bn (≈$60m) in 2024; permits cost ZAR45m (~$2.4m) admin 2024; legacy plants +20–40% energy, −3–6ppt recovery, +$150–$300/oz.
| Asset | Key 2024 metric | Action |
|---|---|---|
| Kusasalethu | $1,250/oz; <200k oz; ZAR1.1bn provision | Phased closure |
| Permits | No revenue; ZAR45m cost | Divest/relinquish |
| Plants | +20–40% energy; +$150–$300/oz | Consolidate/close |
Question Marks
Eva Copper Project Development
The Eva Copper project in Australia is Harmony Gold's strategic entry into a higher-growth copper market but currently represents under 5% of Harmony's 2025 production mix, so it fits the Question Marks quadrant.
It needs about US$200–300m capex to move from development to production and faces Australian permitting and operational risks; if economics hold (projected IRR ~15% at US$9,000/t copper) it could become a Star.
Meanwhile Eva Copper consumes cash for studies and pre‑development; Harmony reported project spend of ~US$18m in FY2025 while it weighs long‑term viability and funding options.
Target 1 Exploration Extensions
Target 1 Exploration Extensions faces a make-or-break re-eval: new drilling could add 0.8–2.5 Moz (million ounces) of inferred gold, or management may opt for a controlled exit to limit losses.
Gold price rose ~15% in 2024 to $2,150/oz; but Target 1 holds <2% regional share and needs ~$45–60M capex to reach feasibility, implying a 4–6 year payback if grades meet targets.
Decision: aggressive funding to chase 10–20% share gains or divest now—delay risks turning the unit into a Dog with negative NPV under $1,800/oz scenarios.
Green Hydrogen Pilot Programs
Harmony is piloting green hydrogen for heavy machinery—a high-growth segment projected to reach 7% CAGR in Africa’s hydrogen economy to 2030—while currently holding 0% market share in this application.
These pilots are cash-intensive: Harmony allocated ~ZAR 150m (≈USD 8.5m) in 2025 capex for trials, largely experimental to hedge against rising carbon taxes of ZAR 200–300/tCO2 scenarios.
Success hinges on tech breakthroughs (electrolyzer cost falls from USD 900/kW in 2024 toward ~USD 300–400/kW) and scaling Southern African H2 infrastructure—only 2 commercial refueling sites exist regionally in 2025.
Digital Twin and AI Mining Integration
Investment in AI-driven exploration and digital twin mine planning is a high-growth, high-uncertainty area for Harmony in the BCG Question Marks quadrant: pilots aim to raise ore-recovery precision by up to 15% (internal trials 2024), but capital intensity is high—R&D and deployment costs ~ZAR 300–500m per shaft.
These techs are a small slice of costs (~2–4% of opex) and haven’t yet shifted market share; industry cases show 5–10% productivity gains where fully adopted, so demand for efficiency keeps funding pilots.
- High growth potential; uncertain returns
- Internal trials: ~15% recovery lift (2024)
- Capex per shaft ZAR 300–500m
- Currently 2–4% of opex; market-share impact unproven
International Joint Venture Prospects
New international joint ventures in Congo, Mongolia and Nevada offer high upside—minerals projects in those jurisdictions could add 15–25% volume growth by 2030—but they now account for <1.5% of Harmony’s 2025 EBITDA and limited cash flow.
These are management- and capital-intensive: typical JV capex per project is $120–220m and permitting timelines average 36–60 months, with geological success rates near 30% for greenfield plays.
They stay Question Marks until showing clear scale and market share; convertibility requires 3–5 years of exploration success, permitting milestones, and an IRR>20% at $1,800/oz gold.
- Current EBITDA contribution <1.5%
- Per-project capex $120–220m
- Permitting 36–60 months
- Greenfield success rate ~30%
- Target IRR>20% at $1,800/oz
High-growth projects, low 2025 impact — major capex ahead (Eva, Target1, AI, JVs)
Question Marks: Eva Copper, Target 1, H2 pilots, AI mining and JV pipeline have high growth but low 2025 contribution (<5% production; <1.5% EBITDA). Key figures: Eva capex US$200–300m, FY2025 spend US$18m; Target 1 capex US$45–60m; H2 pilot ZAR150m (~US$8.5m); AI capex ZAR300–500m/shaft; JV capex US$120–220m, 36–60m permitting.
| Asset | 2025 share | Capex | Notes |
|---|---|---|---|
| Eva Copper | <5% | US$200–300m | FY25 spend US$18m |
| Target 1 | <2% | US$45–60m | 4–6y payback |
| H2 pilots | 0% | ZAR150m | 2 refuel sites region |
| AI mining | 2–4% opex | ZAR300–500m/shaft | ~15% recovery lift (trials) |
| JVs | <1.5% EBITDA | US$120–220m | Permitting 36–60m |
