Results of Updated Scoping Study for Nueva Sabana Mine, Cuba
Antilles Gold Limited (“Antilles Gold” or the “Company”) (ASX: AAU, OTCQB: ANTMF) is pleased to advise the results of the Updated Scoping Study for the first stage of the proposed Nueva Sabana gold-copper mine in Cuba. The Study has been prepared by the 50% owned Cuban joint venture company, Minera La Victoria SA (“MLV”), which is undertaking the project.
- The Updated Scoping Study is based on a pit limited to 100m depth which, at a mining rate of 500,000tpa of ore, will result in an initial mine life of 4.8 years.
- With additional exploration, and a greater mining depth, the project life and NPV could be increased.
- Metallurgical testwork set out in ATTACHMENT C indicates the mine will initially produce a gold concentrate grading ~57.5g/t Au for around 18 months, followed by a blended copper-gold concentrate with an average grade of ~28.3% Cu, and ~29.8g/t Au.
- Payables for these concentrates have been received from a major international commodity trader that the joint venture is negotiating with to establish an offtake agreement.
- The off-take agreement is expected to include a provision for advanced payments for concentrates to assist in the funding of construction costs.
- The 752ha concession covering the Nueva Sabana oxide deposit also hosts the El Pilar, Gaspar, and Camilo porphyry copper intrusives, and numerous shallow gold targets identified by artisanal mining.
- The Nueva Sabana deposit has a small gold cap, an underlying copper-gold zone, and a deeper sulphide copper zone with mineralisation open at depth at 150m which could potentially transition into the El Pilar porphyry copper deposit offset to the south.
HIGHLIGHTS OF FINANCIAL ANALYSIS FOR STAGE ONE OF THE NUEVA SABANA MINE: 
- Estimated Operating Profit of ~US$60M from the first 22 months of concentrate production will comfortably permit repayment of the ~US$28.5M project debt before the end of this period.
- MLV intends to drill the copper mineralisation that continues below the stage one mining depth of 100m with the aim of deepening the Nueva Sabana mine and extending its life.
- The Revised MRE for Nueva Sabana which is incorporated as ATTACHMENT A in the Study, established approximately 25M lb of 0.75% copper in Inferred Resources within the 50m below the initial mine depth, which is a positive indication of the potential to extend its life.
- MLV also intends to drill identified oxide gold-copper targets overlying the nearby Gaspar and Camilo porphyry copper deposits to potentially increase resources.
- Subject to the results of additional drilling, consideration will be given to doubling the mining rate in the copper domain to 1.0Mtpa of ore to increase annual profitability and cash flow.
- It is possible that the Nueva Sabana mine could be significantly expanded and extended in the future to mine the three porphyry copper deposits located within the mining concession.
Antilles Gold Chairman, Mr Brian Johnson, commented: “The first stage of Nueva Sabana, while relatively small, has an excellent IRR and will deliver significant free cash within a short timeframe.
MLV’s priority at this time is to finalise current negotiations on a concentrate off-take agreement for the project, and to arrange financing for the mine construction.
Antilles Gold’s share of the estimated NPV8 for the first stage of Nueva Sabana is ~A$70M at current metal prices of US$2,600 per oz Au, and US$9,300/t Cu, and an exchange rate of A$1.00 = US$0.66, which is significantly higher than the Company’s current market capitalisation of A$7.5M.
The opportunity to unlock further value for Antilles Gold will occur with the proposed development of the joint venture’s flagship project, the La Demajagua gold-silver-antimony mine, where the Company’s share of NPV8 reported to ASX on 30 March 2023 was ~A$150M, prior to the joint venture’s decision to expand the project to produce gold doré from the mine’s gold arsenopyrite concentrate, and to increase antimony production.
Before the end of 2024, Antilles Gold will contribute the final US$0.4M of the US$15.0M earn-in for its 50% shareholding in the joint venture company, Minera La Victoria (“MLV”), after which the Company’s cash burn will be substantially reduced.”

Sranan Gold
Investor Insight
Sranan Gold offers early-stage exposure to a high-impact gold discovery in Suriname’s Guiana Shield, one of the world’s most underexplored gold belts. Backed by the same technical team behind some of the region’s largest gold discoveries, Sranan is a high-leverage discovery story in a mining-friendly jurisdiction.
Overview
Sranan Gold (CSE:SRAN,FSE:P84) is a junior explorer operating in Suriname, a South American nation producing more than 600,000 oz of gold per year. Sranan’s main asset is within Suriname’s prolific Guiana Shield, one of the world’s most underexplored gold belts.
Sample collected from the Tapanahony project’s Poeketi pit.
The company’s flagship asset, the 29,000-hectare Tapanahony gold project, overlays a historic mining belt with strong geochemical and structural indicators. Sranan’s objective is straightforward: convert local knowledge, legacy drill data and modern tools into an inaugural gold resource over a 4.5 km mineralized corridor.
Backed by one of the most credentialed gold discovery teams in Suriname, credited for the Merian, Rosebel and Saramacca deposits, the company is targeting hard-rock gold potential beneath proven saprolite zones with plans to fast-track drilling, build community partnerships and expand its concession footprint.
Company Highlights
- District-scale land position: The 29,000-hectare Tapanahony project covers one of Suriname’s oldest and most productive artisanal mining districts, offering untested hard-rock upside within the Guiana Shield, home to numerous multi-million-ounce gold deposits.
- Immediate drill targets: A 10,000-metre diamond drilling program is set to kick off in 2025 across the 4.5 km Poeketi-Randy trend, targeting high-grade shear zones validated by historic IAMGOLD drilling.
- World-class discovery pedigree: The technical team has led or co-led discoveries at Merian (7 Moz, Newmont), Rosebel (13.7 Moz, now Zijin) and Saramacca (1.5 Moz).
- Deep in-country knowledge: Geologists are locally trained at Anton de Kom University and have decades of experience in Suriname’s regolith-dominated terrain.
Key Project
Tapanahony Gold Project
The Tapanahony gold project is Sranan’s flagship asset, covering a 29,000-hectare land package in southeastern Suriname. The project lies within the Guiana Shield, a well-endowed Paleoproterozoic terrane that hosts multiple Tier-1 gold systems. The property sits at the intersection of regional NW-striking structures, the large NE-SW Tapanahony structure and older NE-SW fabric, forming a favorable setting for orogenic gold emplacement. These structural fabrics, crenulated by later deformation events, are visible in recent LiDAR and magnetic datasets and provide excellent ground preparation for high-grade shear-hosted deposits.
Local miners have long exploited the saprolite horizons here, especially around the Poeketi-Randy zone, and Sranan’s exploration strategy is to transition that surface gold production into a defined, hard-rock resource. The project has seen more than US$10 million in historical exploration, including geochemical soil surveys, auger and panning programs by the UN and Golden Star, and 4,000 metres of diamond drilling by IAMGOLD. They have confirmed the presence of extensive mineralization, including intercepts such as 4.2 grams per ton (g/t) gold over 13.5 m and 39.3 g/t gold over 2 m at the Randy pit. These results suggest steeply dipping, fault-controlled mineralization within a metavolcanic host package, drawing parallels to the structurally hosted gold at the Saramacca, Antino, Merian and Rosebel mines.
The 2025 Phase 1 program is targeting this trend with 10,000 metres of diamond drilling. It will infill and extend the 4.5 km mineralized corridor and test additional parallel shear zones revealed by LiDAR and soil geochemistry in the western lobe of the concession. Sranan plans to reprocess historical drill data, conduct soil/silt sampling, trenching and trench mapping, with field teams prioritizing locations where artisanal mining is ongoing but remains underexplored by modern methods.
Geophysical interpretation highlights a property-scale NW shear zone crosscutting a penetrative NE-SW fabric, which has led to localized folding and thickened mineralized zones. Commonly described by the team as the “double folded” system, they extend across eastern Suriname into Guyana and French Guiana. This orogenic system is thought to be analogous to the geology that underpins other major discoveries in the belt.
Sranan’s Phase 1 campaign also aims to generate new targets through high-resolution LiDAR imaging, which has already revealed three parallel mineralized corridors and topographic inversions associated with lateritic terraces, a common concealment mechanism for mineralization in this region. Pending early success, the company plans to expand drilling into the western lobe, pursue adjoining concessions, and delineate a resource.
