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.”

Key Projects
True North Project
The True North project is 1911 Gold's flagship asset, located in the Rice Lake greenstone belt of southeastern Manitoba, approximately 150 km northeast of Winnipeg. This historically significant mine has produced over 2 million ounces (Moz) of gold and continues to offer substantial exploration upside.
The current mineral resource estimate for True North includes:
- Indicated Resources: 3.52 million tonnes (Mt) at 4.41 grams per ton (g/t) gold, containing 499,000 ounces.
- Inferred Resources: 5.49 Mt at 3.65 g/t gold, containing 644,000 ounces.
These resources remain open for expansion, with multiple high-priority exploration targets identified near existing underground workings.
Geology and Mineralization
The True North deposit is characterized by high-grade, structurally controlled gold mineralization hosted within the Archean Rice Lake greenstone belt. Gold occurs within quartz-carbonate vein systems associated with major regional structures and secondary shear zones. The mineralization extends to significant depths, providing long-term exploration potential.
History
Gold was first discovered at True North in 1911, leading to decades of intermittent mining under various operators. The mine has undergone multiple phases of development, with extensive underground infrastructure, including a shaft extending to a depth of over 1,200 meters. Previous owners, including San Gold Corporation and Klondex Mines, operated the mine until 2017, after which it was acquired by 1911 Gold in mid-2018.
Infrastructure and Geographic Advantages
- A fully permitted 1,300-ton-per-day (tpd) mill, which can be expanded to 2,250 tpd
- A permitted tailings management facility, reducing environmental and permitting risks
- Year-round road access throughout the property with proximity to hydroelectric power
- A 200-person camp and operational support facilities for efficient workforce deployment
Exploration and Development Plans
1911 Gold is focused on expanding the True North resource through an aggressive exploration program. The company has completed 62 surface drill holes (60 to target depth) totaling 14,974.4 metres within the True North Mine footprint. The program, which began in October 2024, is focused on new targets in prospective host rocks and mineralized structural settings, supported by significant historical results. Two rigs are currently drilling at the SAM SE and San Antonio West (SAM W) zones to test depth extensions of mineralization. Planning is also underway for underground exploration drilling, expected to commence by the end of Q3 2025.
The company will leverage True North’s existing infrastructure to restart mining operations efficiently while continuing to explore the vast untapped potential of the surrounding district.
Regional Exploration Projects
In addition to the True North mine, 1911 Gold controls a large-scale land package within the Rice Lake greenstone belt. The company has identified multiple high-potential targets within this district, including:
- Ogama-Rockland: A past-producing high-grade deposit with significant exploration upside
- Central Manitoba: An area with historical production featuring multiple high-grade vein structures with strong exploration potential
- Gunnar: A historic mine representing an additional potential source of mill feed.
The company aims to leverage its central milling facility as part of a "hub-and-spoke" development model, bringing additional satellite deposits into production.
