The Antino gold district lies along the Lawa River in southeastern Suriname.

Gold Fields is deepening its position in Suriname’s emerging gold sector with a C$76.96 million strategic investment in Founders Metals, a transaction that will raise its stake in the explorer to approximately 19.9% and support Founders’ move to full ownership of the Antino gold project.
The investment, announced alongside Founders’ agreement to acquire the remaining 30% of Antino’s holding company from Nana Resources, represents one of the more significant mining M&A deals in 2026 involving a major gold producer and a junior exploration company.
The announced investment is approximately C$77 million, equivalent to about US$55.7 million based on the conversion reported by industry sources. Gold Fields will subscribe for 14,146,850 new Founders shares at C$5.44 per share, representing the five-day volume-weighted average price through August 17.
Following completion, Gold Fields is expected to hold just below 20% of Founders Metals. The transaction remains subject to final approval from the TSX Venture Exchange and other customary closing conditions.
Gold Fields backs Antino consolidation
The private placement is being completed at the same time as Founders’ agreement to purchase Nana Resources’ remaining interest in Lawa Gold N.V. Lawa holds the mineral rights, concessions and infrastructure that comprise the Antino project.
Founders currently owns 70% of Lawa. Acquiring Nana’s 30% interest would give the Canadian explorer a 100% interest in Antino on a royalty-free basis.
The project covers approximately 102,360 hectares in southeastern Suriname, within the Guiana Shield. It is located about 275 kilometres south of Paramaribo, along the Lawa River opposite French Guiana.
For Founders, full ownership removes the need to share operational decisions or future project economics with a local partner. It also gives the company greater flexibility over exploration planning, development studies, permitting and potential infrastructure decisions.
“This is a defining moment for Founders,” President and CEO Colin Padget said in the company’s announcement. He said full ownership would give Founders control of the entire district as it enters a major phase of exploration and development.
Gold Fields’ decision to increase its holding was described by Padget as an endorsement of Antino’s potential and the company’s exploration team.
Transaction terms and milestone payments
Founders will pay Nana Resources US$17 million in cash and issue 13,568,944 Founders shares. Nana will also be eligible for up to US$21 million in contingent payments tied to project milestones.
The milestone structure links part of the consideration to the future technical and commercial progress of Antino:
| Milestone | Contingent payment |
|---|---|
| Technical report outlining at least 3 million oz. of measured, indicated and inferred resources | US$3.75 million |
| Receipt of material permits required for commercial mining | US$3.75 million |
| Board approval of a decision to construct a commercial mine | US$3.75 million |
| First gold pour from a processing plant exceeding 2,000 tonnes per day | US$3.75 million |
| Cumulative production exceeding 600,000 oz. from a plant exceeding 2,000 tonnes per day | US$6 million |
| Total potential milestone payments | US$21 million |
The structure limits Founders’ immediate cash requirement while providing Nana with additional value if Antino reaches defined resource, permitting, construction and production thresholds.
Nana is expected to own approximately 10.6% of Founders after receiving the consideration shares and combining them with its existing position. The company will also be subject to an investor rights agreement that restricts the transfer of the consideration shares for six months.
The cash component of Nana’s payment will be funded primarily through the Gold Fields investment. The remaining proceeds will support regional exploration, working capital and general corporate purposes at Antino.
Exploration is moving toward a first resource
Antino does not yet have an initial mineral resource estimate. Founders is instead using the new capital to advance a large exploration program, including approximately 70,000 metres of drilling during 2026.
The company has reported multiple mineralized zones across the district since beginning intensive drilling in 2023. In July, Founders reported that the first drill hole at the Antino Northeast target intersected 58.5 metres grading 1 gram of gold per tonne from a depth of 18.6 metres. Two follow-up holes confirmed mineralization to the south along a reported strike length of 1.2 kilometres.
Earlier drilling at the Lower Antino target returned 90 metres grading 1.02 grams per tonne from 156 metres depth. Founders has said the zone could complement the more advanced Upper Antino area as the company works toward a district-scale resource base.
The project also has a long history of artisanal mining. Industry reports estimate that approximately 500,000 ounces of gold have historically been recovered from artisanal operations on the property. That history provides geological context, but it does not represent a compliant mineral resource or reserve for Founders.
Exploration drilling is central to Founders Metals’ campaign at Antino.
A strategic foothold for Gold Fields
Gold Fields first invested approximately C$50 million in Founders in late 2025, acquiring a stake of about 12% and becoming the junior’s largest shareholder. That investment also gave Gold Fields board and technical committee rights.
The latest placement would bring the major producer close to the 20% ownership threshold, reinforcing its strategic relationship with Founders without taking full control of the company.
For Gold Fields, the transaction offers exposure to a large and still largely untested gold land package in a jurisdiction where established producers already operate. Newmont’s Merian mine and Zijin Mining’s Rosebel operation demonstrate that Suriname can support industrial-scale gold production, although project development remains dependent on infrastructure, permitting, local operating conditions and community relations.
Gold Fields has operations across Africa, Australia and the Americas. The company produced approximately 2.44 million ounces of gold in the previous year, according to industry reporting. Its investment in Founders gives it an option to maintain strategic exposure to Antino while the explorer defines the project’s geology and economic potential.
The deal also places Founders among a growing group of junior companies seeking to establish a position in Suriname’s gold sector. The country’s Guiana Shield geology has attracted additional exploration activity from companies including Sranan Gold, Miata Metals and Greenheart Gold.
Closing conditions and key risks
The Gold Fields placement and the Nana transaction are expected to close on or about September 4, subject to regulatory and transaction conditions. The outside date is November 30, with a possible 90-day extension by mutual agreement.
The transactions require final TSX Venture Exchange approval. They also depend on the completion of the Gold Fields investment, the absence of a material adverse effect and Nana’s permanent cessation of involvement in alluvial operations at Antino.
For investors and operators assessing this development as part of gold mining news in 2026, the immediate change is ownership and funding rather than production. Founders will control a larger project package and have access to additional capital, but Antino remains an exploration-stage asset.
The main technical risk is whether drilling can define a sufficiently large and economic resource. Additional risks include permitting, infrastructure construction, metallurgy, financing requirements and the ability to develop operations in a remote region along the Lawa River.
The milestone payments may reduce near-term dilution from the Nana acquisition, but they would become payable only if Antino advances through major technical and commercial stages. Similarly, Gold Fields’ investment strengthens Founders’ balance sheet but does not remove the need for further exploration success or future development capital.
Core logging will help define the continuity and grade distribution of mineralized zones.
What the deal changes
The transaction gives Founders three immediate advantages:
- Full project control: Founders will own 100% of Antino’s mineral rights, concessions and infrastructure through Lawa Gold.
- A stronger funding base: The Gold Fields placement provides capital for the Nana buyout and continued drilling.
- A strategic major shareholder: Gold Fields will hold approximately 19.9% of Founders, maintaining a close connection to the project as exploration advances.
The next key test will be whether Founders can convert exploration results into a first mineral resource estimate and demonstrate continuity across the Antino district.
Until then, the transaction is best understood as a consolidation and exploration-financing deal rather than a mine-development commitment. Gold Fields is increasing its exposure to a prospective Suriname gold district, while Founders is taking on full ownership and responsibility for proving that the project can support a commercial operation.
