About GBSC 360 Mining
A green acquirer of brownfield gold.
We are not an exploration company. We target brownfield assets with defined Mineral Reserves and installed plant, where the constraint is operating cost, capital or management.
GBSC 360 Mining is a new company, launched by an experienced team. Our technical base carries out due diligence on every target and manages operations after acquisition, so each asset is assessed by the people who will run it.
Our approach
What we acquire, and how.
Target assets
- Properties with Proven and Probable Reserves and exploitation permits in hand
- Producing operations running below nameplate or short of working capital
- Assets on care and maintenance with recoverable plant and infrastructure
Transaction structures
- Share acquisition. Equity in the company that holds the mining title.
- Earn-in. A staged interest earned against funded expenditure and operatorship.
- Debt financing. Secured or offtake-linked facilities serviced from production.
Operating standard
- Solar PV and battery storage displacing diesel and HFO generation
- Closed-circuit process water and reagent management, mercury-free recovery
- Engineered tailings storage and progressive rehabilitation
- National workforce, local procurement and local equity participation
How an acquisition works
- 01 · IntroductionThe owner, financier or adviser introduces the asset under a confidentiality agreement.
- 02 · Due diligenceG Force Mining Consultants audit the reserve, mine plan and plant. We build the LOM cash-flow model and reserve valuation.
- 03 · StructuringWe agree the route in: share acquisition, earn-in or debt financing, with the state's interest modelled from the outset.
- 04 · OperatorshipWe take over site management and bring the operation back to nameplate throughput on the green standard.
Technical base: G Force Mining Consultants
G Force Mining Consultants are the technical base and resource of the company: geology and resource estimation, mine planning, metallurgy and site management. They carry out technical due diligence on each target and manage operations after acquisition.
Technical and financial evaluation
How we evaluate an asset.
Every target goes through two tracks before we commit capital. The technical track tests the orebody, the mine plan and the plant. The financial track converts the life-of-mine (LOM) plan into a reserve valuation and a production forecast we are prepared to operate to.
Track 1 · Technical
Resource and reserve audit
Review of the drill-hole database, QA/QC, geological model and block model. We check the estimation method and the classification of Measured, Indicated and Inferred Mineral Resources, then the modifying factors that convert them to Proven and Probable Mineral Reserves. Estimates are read against NI 43-101 and CIM Definition Standards, the JORC Code or SAMREC.
Mine plan and geotechnical review
Cut-off grade, strip ratio, dilution and mining recovery. Pit slope or stope design, bench and haul-road geometry, fleet productivity and equipment availability. Grade control practice and mine-to-mill reconciliation show whether the reserve model predicts what the mill receives.
Metallurgy and plant audit
Head grade, throughput against nameplate, plant availability and utilisation. Metallurgical recovery by ore type: oxide, transition and fresh or refractory. Reagent, grinding media and power consumption per tonne milled, gold-in-circuit inventory and remaining tailings storage capacity.
Track 2 · Financial and mining accounting
Reserve valuation
Discounted cash flow of the LOM plan gives net asset value: NPV at a 5% real discount rate, the gold-sector convention, and at a country risk-adjusted rate, with IRR and payback period. Market cross-checks use enterprise value per reserve ounce and per resource ounce, and price to NAV, against comparable transactions.
Production forecast analysis
The LOM schedule is rebuilt from ore tonnes mined, mined grade, mill throughput and recovery to gold poured. We compare forecast with actual over trailing periods, test the ramp-up curve, and run sensitivities on gold price, grade, recovery, operating cost and capital. Downside cases set the price we will pay.
Cost and mining accounting
Cash cost and all-in sustaining cost (AISC) per ounce on World Gold Council guidance, with sustaining and growth capital separated. We review deferred stripping, depletion on a units-of-production basis, the rehabilitation and closure provision, impairment indicators, and the royalty, free-carried interest and tax lines in the fiscal model.

Our team
An experienced team, a new company.
GBSC 360 Mining launches with four partners who have built and run businesses across mining, finance and trade on three continents. Each holds an equal 25% interest.
State of the industry
African gold, country by country.
Africa accounts for about a quarter of global mine supply. These are its ten largest producers. Choose a country to read its industry, labour, fiscal and political briefing, and the asset availability we see there.
Gold output, 2024
Tonnes. World Gold Council figures as reported by Daba Finance and Le360.
State free-carried interest
Percent of each mining company the state receives without paying, under the current mining code. Mali can add 20% by purchase and reserves 5% for local investors.
Gold as a share of export earnings
Approximate percent, latest reported figures.
Human Development Index
UNDP Human Development Report 2025 (2023 data). Scale 0 to 1. Below 0.550 is classed as low.
With gold above $4,000 an ounce, governments have raised royalties, increased free-carried interests and begun to mandate in-country refining. Every jurisdiction here also mandates local content: national employment, training and procurement.
Technology
More gold, less waste.
An under-performing operation usually carries a high strip ratio, poor plant recovery, or both. We assess these technologies at every site.
Sensor-based ore sorting
XRT and laser sensors reject barren material ahead of the comminution circuit. Mill head grade rises, and power, water and reagent consumption per ounce fall. Navachab in Namibia reports higher recovery and lower opex with STEINERT sorters.
Autonomous and battery-electric haulage
Load-and-haul is the largest diesel consumer in an open pit. Komatsu commissioned its 1,000th autonomous ultra-class truck in April 2026, at Nevada Gold Mines. EACON reports its autonomous haulage system on more than 1,500 battery-electric trucks.
Leaching and cyanide management
Cyanidation through CIL or CIP remains the industry standard. Modern plants run closed circuits with cyanide detoxification ahead of tailings discharge. Thiosulfate leaching and bio-oxidation suit some refractory ores. At small scale, gravity concentration replaces mercury amalgamation.
Filtered dry-stack tailings
Filtering and dry-stacking removes the conventional wet tailings storage facility, the largest single environmental liability at a gold operation, and returns most process water to the plant.
Tailings retreatment
Historic tailings carry gold that earlier circuits did not recover. DRDGOLD's surface retreatment business in South Africa recovers it while rehabilitating legacy sites.
Modular water treatment
Containerised treatment plants can be mobilised to remote sites. WEC Projects and Multotec engineered one for a gold mine in Mali.
Energy
Power: the cost we can change.
Most African gold operations are off-grid or on a weak grid. Power is one of the largest components of all-in sustaining cost (AISC) and the first place we look for savings.
Consumption and sourcing
- Comminution (crushing and grinding) draws most of a plant's power.
- Off-grid sites run diesel or heavy fuel oil (HFO) gensets, with fuel hauled hundreds of kilometres over poor or insecure roads.
- Fuel price and security of supply are exposed to events far from site.
- Where a grid exists it is often weak. Only 22.1% of people in the DRC had electricity in 2023. South African mines lived through years of load curtailment.
Hybrid power
- Solar PV by day, battery storage for grid stability, thermal units as backup.
- Essakane, Burkina Faso: 15 MW of solar saves about 6 million litres of fuel and 18,500 tonnes of CO₂ a year.
- Sadiola, Mali: Allied Gold expects its staged energy programme to cut AISC by $150 to $200/oz.
- Ergo, South Africa: DRDGOLD's electricity cost fell 23% with its own solar plant and battery, despite tariff increases.
Solar built or planned at gold mines
Megawatts of solar capacity. Company and trade press reports.
Fekola also runs a 15.4 MWh battery. Sadiola's solar plant is planned for 2027 with a 30 MWh battery.
Assets available
Six classes of asset.
Gold assets are seldom marketed openly. Across these jurisdictions many are available at the right price, and their owners want to work with a proven, experienced operating team. Specific properties are discussed under a confidentiality agreement.
Images are illustrations. Site photographs will be added as assets are cleared for disclosure.
Impact
What better mining can change.
Gold pays for a large share of public life in these countries, yet several rank near the bottom of the UN's Human Development Index. The gap between the two is the opportunity.
Revenue that reaches the state
Formal mines pay royalties and tax. Smuggled gold pays nothing. Zimbabwe was estimated to lose some 22 tonnes a year to smuggling.
Jobs and local funds
Each restarted mine brings direct employment, contractor work and local procurement. South African mining employs about 472,000 people.
Cleaner land and water
A restarted mine run to a modern standard replaces mercury and unmanaged pits with treated water, managed tailings and land that is rehabilitated as mining moves on.
