Blyvoor Gold Mine: Owner, Output, Reserves and Mine Life

Blyvoor Gold Mine is an underground gold mine in the Carletonville goldfield of South Africa, 14 km southwest of Carletonville and 80 km southwest of Johannesburg. Blyvoor Gold Capital holds the mine, and Aurous Gold holds 74% of that company, according to a January 2025 SEC proxy filing. The filing reports 3.80 million ounces (Moz) of mineral reserves at 5.54 g/t, a 34-year mine plan and 22,155 ounces produced in the year to February 2024.

This page is a working profile for mining consultants and other professionals. It sets out who owns what, what the mine has produced against its plan, what the reserve figures mean, and where the technical risks sit. It also corrects a common error: older web pages describe Blyvoor as a large modern employer with thousands of jobs, when the filing shows a much smaller operation still rebuilding.

Blyvoor gold mine at a glance

Two terms recur on this page. Grade in g/t means grams of gold per tonne of rock. A reef is a thin, gold-bearing layer of conglomerate, the pebbly rock that hosts Witwatersrand gold.

Who owns Blyvoor Gold

The ownership chain has two layers. Aurous Gold holds 74% of the mine through Blyvoor Capital. The other 26% is a BEE stake, split into 20% for the Blyvoor Workers Trust, 3% for the Blyvoor Community Trust and 3% for a vehicle focused on black entrepreneurs. A sister company in the same group, Gauta Tailings, holds 100% of the Gauta Tailings Project next door.

Orion Resource Partners, a US fund manager, has backed Aurous, as Miningmx reported in 2024. The same report names Richard Floyd as chief executive, and says Aurous had spent US$125 million on the revival by then. Peter Skeat, the late gold entrepreneur who bought the mine out of liquidation, is remembered in the name of the main shaft.

The Nasdaq listing that did not close

In March 2024 the group agreed to merge with Rigel Resource Acquisition Corp, a blank-cheque company, in a deal law firm Milbank valued at US$362 million. The combined company was to be called Aurous Resources and list on Nasdaq. It did not happen. On 7 November 2025 Rigel told the SEC that the parties had ended the agreement by mutual consent and that it would not complete a business combination before its 9 November 2025 deadline.

Anyone reading older articles should keep this in mind: they may describe Aurous Resources as a soon-to-be listed company. Blyvoor has no stock ticker from that deal. This page is for information only and is not investment advice.

Blyvoor gold mine history: from richest reef to liquidation

The mine dates from 1937 and was the first on the West Wits line, the western extension of the Witwatersrand gold belt. Production began in 1942 under Rand Mines. The name is not a phrase meaning better conditions, as some web pages say. The farm name Blyvooruitzicht is of Dutch origin and means happy prospect.

4. 4RebuildAssets bought from 2014, refurbished 2019-2021.
5. 5RestartProduction resumes in fiscal 2022.

The early results were remarkable. The SEC filing says Blyvooruitzicht was declared South Africa’s most profitable mine in 1950, built its first uranium plant that year, and had the highest gold output in the world in 1951. It puts cumulative output from the current mining right area, which includes the old Doornfontein mine, at over 50 Moz between 1942 and 2021.

Ownership then changed hands several times, and the decline after 2010 was fast.

• 1995: Blyvooruitzicht and Doornfontein merge under Rand Mines.
• 1997: DRD (now DRDGOLD) buys the merged company.
• 2009: DRDGOLD plans a court order to avoid liquidation, with monthly losses of almost US$3.62 million by October.
• 2011-2012: Village Main Reef buys the mine. The filing dates the purchase to 2011 and the Mail & Guardian to 2012.
• 2013: Production stops and the operating company enters provisional liquidation.
• 2014-2016: The present owners buy the plant, then the main shaft complex and the mining right.
• 2015: Gauta Tailings buys six tailings dams.
• 2017: The mining right moves to the new owner.
• 2019-2021: The main shaft complex is refurbished and a new treatment plant is built.
• Fiscal 2022: Production restarts.

The gap between closure and restart left deep damage. In 2014 the Mail & Guardian described a town being stripped of pipes and metal, illegal miners working the site, and dust blowing off the tailings. The paper reported that dozens of illegal miners had died. A R37 million rehabilitation fund was tied up in the liquidation.

During the liquidation AngloGold Ashanti bought No. 4 and No. 6 shafts, later passing them to Harmony Gold, and took over pumping through them to protect its own neighbouring mines. That split still matters: water control on this ground depends partly on third parties.

Blyvoor gold production compared with the mine plan

Production since the restart has been small. The filing gives these unreviewed figures: 5,154 oz in the year to February 2022, 27,071 oz in the year to February 2023 and 22,155 oz in the year to February 2024. The six months to August 2024 added 10,934 oz. That is well short of the plan average of about 142,000 oz a year.

Troy ounces, years ending February

The plan expects output to pass 80,000 oz in plan year 3 and 87,000 oz in year 4. To get there, the filing lists opening up level 15, recommissioning the sub-vertical shaft, and dewatering flooded workings. In 2024 Richard Floyd spoke of growing from about 30,000 oz a year to 150,000 oz or more, with about US$50 million expected from the listing. That listing money did not arrive through the Rigel deal.

We calculated recovered grade by converting ounces to grams and dividing by tonnes milled. It is a rough check on what reached the gold room, not a reported head grade, so it does not compare directly with the 5.54 g/t reserve grade. Even so, a consultant would want to know why it sits below the reserve figure, and whether dilution, waste or low-grade feed explains the gap.

Blyvoor reserves, resources and grade

The figures below date from 29 February 2024 and come from technical report summaries prepared under the US SEC’s S-K 1300 mining rules. Reserves are stated as delivered to the plant, while resources are stated in place and exclude reserves, so never add the two without adjustment.

Blyvoor gold by category

Reserves assumed a long-term gold price of US$1,900/oz, R19.15 to the US dollar and a cut-off of 496 cm.g/t. That cut-off unit multiplies reef width in centimetres by grade, because narrow reefs are judged by the gold per unit of area, not by grade alone. Inferred resources carry high uncertainty, and the filing itself warns that resources outside reserves have no demonstrated economic value. Readers can compare this with other deposit styles in our guides to types of ore deposits and gold deposit types.

Reef thickness shapes everything here. Mining Technology describes the Carbon Leader and Main Reef horizons as only 5 cm to 20 cm thick. The filing says Middelvlei Reef grades have averaged around half those of the Carbon Leader. Note that the older mine profile’s 25.85 Mt of reserves and DRDGOLD ownership predate the 2013 closure and should not be quoted as current.

Cost figures

The plan’s average all-in sustaining cost (AISC) is US$905/oz over the mine life. AISC adds sustaining capital and overheads to direct cash costs. In 2024 Miningmx reported a then-current AISC of about US$1,100/oz. One veteran, Harmony founder Bernard Swanepoel, called the listing speculative in that same article. Treat US$905/oz as a plan target, not a result.

Gold stream

Reported revenue overstates what the owner keeps. A stream agreement with Sandstorm Gold, brought in a US$37 million prepayment. In return the mine must sell 10% of annual production at the lower of US$572/oz and the LBMA afternoon price, capped at 16,000 oz a year, until 300,000 oz are delivered. Until then it must also sell 5% of any output above 160,000 oz a year. After that the share falls to 0.5%, capped at 500 oz a year. A stream is a sale of future metal at a fixed low price, so any valuation has to take it out.

Mine life compared with the mining right

The 34-year plan runs longer than the current title. The mining right started on 17 February 2017 and runs to 16 February 2047, which leaves about 23 years from the plan date. The right can be renewed if the holder applies at least 60 working days before expiry. It also covers about 6,708 ha, and it can be suspended or cancelled if the holder breaches its conditions. A 34-year number therefore assumes a renewal, plus funding and ramp-up on schedule.

How Blyvoor compares with South African gold output

South Africa is no longer the leader it once was. USGS estimates put its 2025 mine output at about 90 tonnes, out of a world total of about 3,300 tonnes, with reserves of 5,000 tonnes. In tonnes, the 22,155 oz Blyvoor produced in the year to February 2024 equals about 0.69 t, under 1% of that national output. For wider context see our list of major gold-producing countries and our ranking of the largest gold mining companies.

Chart

Gold mine output in selected countries

Tonnes, 2025 estimates

The geology is still world class. The Witwatersrand Basin has produced over 40,000 tonnes of gold. Blyvoor’s neighbours include Harmony’s Mponeng mine, which works to about 3.8 km depth, plus Sibanye-Stillwater’s Driefontein. Those neighbours are one reason the Blyvoor case attracts attention, since Harmony has been investing to extend Mponeng in the same area.

Small-scale gold work elsewhere is a very different business. Hobby prospecting, as in our guide to gold panning locations in US rivers, needs permission, safe methods and no mercury, while deep-level work needs shafts, cooling and pumping at industrial scale. For a US contrast in old district revival, see Goldfield, Nevada.

Sustainability and environmental risks at Blyvoor

The public record points to six practical risk areas for anyone assessing this ground.

• Sinkholes: Large parts of the mine sit under dolomite, a soluble rock, and the filing records surface instability linked to dewatering. In 1964 a sinkhole at Westdene in the mine village killed a family and their domestic worker.
• Acid mine drainage: Old Witwatersrand workings can release acidic, metal-rich water once flooded, as EARTH Magazine explains for the wider region. Dewatering flooded levels is also part of Blyvoor’s plan.
• Dust: Tailings dust was a leading complaint in 2014. It remains the kind of issue that surface retreatment can reduce or worsen, depending on the method.
• Health and safety: The filing names silica dust, noise and heat as the main occupational exposures, and silicosis and tuberculosis among the significant diseases. It also notes methane intersections.
• Security: The filing lists artisanal and illegal mining as an operating risk.
• Environmental authorisation: The filing says the mine received authorisation for underground operations in February 2020.

Gauta Tailings Project

Gauta aims to reprocess old tailings dams, the fine waste left after earlier gold recovery. The filing lists 84.27 Mt of probable reserves at 0.30 g/t for 0.82 Moz, plus inferred resources of 58.32 Mt at 0.28 g/t for 0.53 Moz. It is a prefeasibility-stage project with minor uranium and sulfide content. At the time of the filing the feasibility study had not started and was not expected before fiscal 2026. Richard Floyd said in 2024 it could add about 30,000 oz a year.

What consultants should check on Blyvoor

If you are reviewing this asset for a client, a lender or a neighbouring operator, these are the checks that matter most.

1. Latest output: ask for monthly tonnes, grade and ounces after August 2024.
2. Funding: confirm what replaced the Rigel money and which projects it covers.
3. Reconciliation: compare mined, milled and reserve grade, using reef width and dilution.
4. Water: review pumping duties, third-party dependence and costs for dewatering.
5. Ground and surface stability: review dolomite risk maps and seismic records.
6. Stream: model Sandstorm deliveries against planned ounces, and confirm the current holder.
7. Rehabilitation: confirm liabilities, including historic areas now owned by third parties.
8. Assays: use an independent lab where possible. Our guide to assay services outlines the options.

Where satellite imagery fits on a legacy goldfield

Satellites cannot see a reef at depth, so they will not replace underground sampling or the technical reports above. They can show surface change over time on the same ground: tailings footprints, vegetation on rehabilitated areas and new surface disturbance. Farmonaut’s satellite mineral screening produces exploration targets ahead of any resource estimate, not a JORC or NI 43-101 result, and takes coordinates or a KML file as input.

Separate Farmonaut pages cover carbon footprinting, fleet management, product traceability, satellite verification for lenders and the API documentation. Farmonaut has no stated link with Blyvoor Gold or Aurous.
