Investor Insight
Antilles Gold’s gold and copper projects in Cuba are underpinned by a strong partnership with a Cuban Government-owned mining company that effectively fast-tracks and de-risks its promising projects, offering a strategic value proposition for investors.
Overview
Antilles Gold (ASX:AAU,OTCQB:ANTMF) is an Australian mining company focused on gold and copper projects in Cuba through a joint venture with the Cuban Government’s mining company, GeoMinera. This partnership has resulted in rapid project permitting and access to several new development opportunities for the Australian company.
Antilles Gold offers strong growth potential through two near‐term development projects, Nueva Sabana and La Demajagua, and two exploration projects, the El Pilar porphyry system and Sierra Maestra copper concessions.
Joint venture projects in Cuba
Nueva Sabana is a near‐term, gold‐copper mine development within the joint venture with GeoMinera, and is expected to initially produce around 70 grams per tonne (g/t) gold in a concentrate from a high‐grade gold cap followed by ~27 percent copper concentrate with gold credits. The project development strategy includes the completion of a feasibility study in September 2024, and the commencement of construction soon after.
The second proposed development is the La Demajagua open-pit mine, which is likely to produce ~50,000 tonnes per annum (tpa) of gold arsenopyrite concentrate (32 g/t gold, 27 percent arsenic), and ~10,000 tpa of gold antimony concentrate (28.8 g/t gold, 48 percent antimony, 1,200 g/t silver) for nine years. According to the plans, construction will commence in late 2025, with commissioning in mid‐2027. La Demajagua will also include the construction of a concentrate processing facility to treat La Demajagua’s gold arsenopyrite concentrate, with the capacity to produce 50,000 oz gold per year in dore, which will further increase JV profit and cashflow.
The joint venture’s two exploration projects comprise the 720‐hectare El Pilar Concession in Central Cuba covering a cluster of three copper‐gold porphyry deposits (El Pilar, Gaspar and San Nicholas), the adjacent 17,000 hectare San Nicholas concession with porphyry style mineralisation, and two concessions totaling 52,600 hectares within the producing Sierra Maestra copper belt in southeast Cuba (La Cristina and Vega Grande), with both indicating of porphyry deposits highly prospective for copper, gold and molybdenum.
Surface mineralisation at El Pilar
Antilles Gold has completed a technical evaluation of the El Pilar porphyry system which was advised to ASX on 15 February 2024.
The joint venture intends to invest part of the surplus cash flow from the Nueva Sabana mine to fund the exploration of major copper targets, including the El Pilar copper‐gold porphyry system, and those in the Sierra Maestra copper belt.

Key Projects
Nueva Sabana Project
Prominer Mining Technology will supply Nueva Sabana concentrator
Nueva Sabana is the company’s near‐term, gold‐copper mine development project. The project is held in the 50:50 joint venture with GeoMinera. It will be an open-pit mine developed on the oxide zone overlaying the El Pilar porphyry copper deposit in central Cuba.
Results from 24,000 metres of historical drilling, 1,800 metres drilled in 2022, and the 10,000 metres drilled in 2023 have established a mineral resource estimate (MRE). Results of a scoping study were advised to ASX on 7 May 2024, and a feasibility study is in progress for the proposed development which will be followed by a 12‐month construction phase.
Drilling has shown outstanding grades for gold and copper, and increasing lateral and vertical boundaries of the copper domain.
The proposed mining rate for the project will be 500,000 tpa of ore with a low waste‐to‐ore ratio. The anticipated initial production of 70 g/t gold concentrate will be followed by a ~27 percent copper concentrate with gold credits.
The estimated project cost is approximately US$33 million, of which approximately US$6 million is shareholders equity with the balance of $27 million expected to be funded through an advance on purchases of the concentrates by an international commodities trader.
Chinese engineering group, Prominer Mining Technology, which has extensive experience in designing and constructing gold and copper concentrators, is expected to supply the crushing and flotation circuits for the Nueva Sabana mine.
La Demajagua Project
La Demajagua involves the development of a gold‐antimony‐silver deposit as an open-pit mine by the joint venture company, Minera La Victoria.The project is located within a 900 hectare mining concession on the Isle of Youth, 60 nautical miles from mainland Cuba. The project site is 35 kilometres from the port city of Nueva Gerona and enjoys excellent infrastructure in terms of accessibility by highway, and availability of water, electricity and fiber optic cable.The project has an MRE of 905,000 oz gold equivalent for the open-pit operation. The MRE was calculated from 29,000 metres of drilling undertaken by the JV, and selective results from about 50,000 metres of historic drilling and revised after the receipt of additional antimony assays. The project expects mining of about 815,000 tpa of ore to produce two concentrates: 50,000 tpa of gold‐arsenopyrite and 10,000 tpa of gold‐antimony‐silver for nine years.
The project will also include a concentrate processing facility to produce gold doré from the gold-arsenopyrite concentrate. The facility will comprise a 50,000‐tpa two‐stage fluidized‐bed roaster, a carbon-in-leach (CIL) circuit, and an antimony recovery circuit. The overall production target is 75,000 oz gold equivalent per year. Chinese engineering firm BGRIMM Technology Group, which has extensive experience in designing and constructing roasters, is expected to supply the process plant on a turnkey basis.
The total development cost is estimated at US$165 million, expected to be funded by US$75 million of equity, which includes contributions by a third shareholder in the project, and the balance of US$90 million in debt. The life‐of‐mine cash surplus is estimated at ~US$600 million, with an NPV of ~US$330 million based on US$1,800/oz gold, and US$13,000/t antimony.
A revised scoping study including the concentrate processing facility is expected in December 2024, and construction is anticipated to commence in late 2025, with commissioning targeted for mid‐2027.
El Pilar Copper‐Gold Porphyry System Project
El Pilar is an exploration project of a cluster of three copper‐gold porphyry deposits: El Pilar, Gaspar and Camilo. The project comprises a 752 hectare exploration license and an adjacent 17,000 hectare reconnaissance permit covering the San Nicholas copper targets.
The project site benefits from established infrastructure with close access to a major highway, high‐tension power, and a 60 kilometre rail link to Palo Alto port.
Previous mapping, soil sampling, ground magnetics, an aeromagnetic survey and 24,000 metres of shallow drilling confirmed the existence of copper‐gold mineralization and identified the exposures as a potentially large, leached porphyry system. The surface exposures at El Pilar are leached phyllic caps to a cluster of copper‐gold porphyry cores. The extent of surficial hydrothermal alteration indicates the porphyry intrusions have large dimensions, and potential depths greater than 1,000 metres.
Ground magnetics and induced polarization surveys in early 2023 have confirmed a cluster of three potentially large porphyry intrusives – El Pilar, Gaspar and Camilo. A 10‐hole initial program has demonstrated positive results with good copper intercepts in porphyry‐style veining and has indicated the proximity of drilling to the core of El Pilar porphyry intrusive. In particular, drill hole PDH‐004A assayed 1.23 percent copper over its length of 134 metres from 49 metres.
Sierra Maestra Copper Belt Project
The project is an exploration project covering two highly prospective concessions for copper, gold and molybdenum in the Sierra Maestra copper belt in southeast Cuba. It includes a 3,600-hectare geological investigation license in La Cristina, and the adjoining 49,000‐hectare Vega Grande reconnaissance license.
The copper belt spans more than 200 kilometres of Cretaceous‐age geology intruded by Eocene stocks, which are the source of widespread gold and base‐metals mineralization. The project is near the El Cobre mine which is the oldest operating copper mine in the Americas. The concessions incorporate a series of copper‐gold‐molybdenum zones that display significant footprints of hydrothermal alteration normally associated with potentially large porphyry systems.
An extensive, two‐year prospecting program will be carried out on the two concessions, commencing in Q4 2024, to identify drill targets.

Shallow, High-Grade Gold Mineralisation Intersected at Barimaia Gold Project
Key Points:
- Significant results received from the second phase of shallow Reverse Circulation (RC) drilling at the McNabs East Prospect at the Barimaia Gold Project in Western Australia, including:
- 2Gm @ 2.52g/t Au from 81m 24BARC083
- Including 1m @ 47.5g/t Au from 107m (visible gold present)
- 4m @ G.62g/t Au from 5Gm 24BARC102
- Including 1m @ 32.7g/t Au from 60m
- 25m @ 1.50g/t Au from 56m 24BARC087
- 5m @ 4.61g/t Au from 61m 24BARC104
- Including 1m @ 1G.6g/t Au from 64m
- 16m @ 1.23g/t Au from 5m 24BARC103
- 15m @ 1.24g/t Au from 30m 24BARC07G
- 2m @ 6.62g/t Au from 42m 24BARC0G7
- 7m @ 1.6Gg/t Au from 73m 24BARC07G
- 2Gm @ 2.52g/t Au from 81m 24BARC083
- Extensive zone of gold mineralisation now defined at McNabs East at shallow depths (typically <80m vertical) over a strike length of +1,000m and remains open along strike and untested at depth.
- The recent shallow drilling at McNabs East was completed on ~100m-spaced sections to continue the first-pass test of the Barimaia felsic intrusion.
- Primary mineralisation in the McNabs East area is associated with an interpreted granodiorite intrusion, strongly supporting the potential for Eridanus-style deposits at Barimaia.
- Diamond drilling planned for November to obtain structural and lithological data at McNabs East, which will be followed by extensional and in-fill RC drilling in the March 2025 Ǫuarter.
The RC drilling program was completed in September and October 2024 as the second phase of a larger, ongoing program to systematically test at shallow depths (typically < 80m vertical) the currently defined 2.5km strike extent of gold mineralisation at Barimaia.
Results from the program continue to confirm shallow, open pit potential, with coherent zones of gold mineralisation starting to be defined within an extensive gold system that remains untested at depth and remains open along strike.
Drilling completed on section 585,640E (see Figures 1 and 2) returned significant high-grade gold mineralisation in 24BARC083 (2Gm @ 2.52g/t Au from 81m) to the end of the hole (EOH) at 110m.
Visible gold was panned in the interval from 107m to 108m, which returned an intercept of 1m @ 47.5g/t Au.
Strong gold mineralisation was also returned from 24BARC087 (25m @ 1.50g/t Au from 56m) on section 585,550E (see Figures 1 and 3), adjacent to where a robust zone of gold mineralisation was intersected in drilling completed in August 2024 in 24BARC056 (21m @ 1.60g/t Au from 62m) and 24BARC057 (36m @ 0.85g/t Au from 50m). This interpreted flat-lying zone of gold mineralisation is over 80m wide on section.
Drilling completed on the eastern limit of the Phase 2 program on section 586,300E (see Figures 1 and 5) returned high-grade gold mineralisation in two separate zones, including 4m @ G.62g/t Au from 5Gm in 24BARC102 including 1m @ 32.7g/t Au from 60m; and 5m @ 4.61g/t Au from 61m in 24BARC104 including 1m @ 1G.6g/t Au from 64m. Importantly, no RC drilling has been completed east of this line along the interpreted strike of the mineralisation.
Management Comment
Commenting on the results, Ordell’s Managing Director, Michael Fowler, said:
“Our second drill program at Barimaia has delivered some great results, with wide zones of shallow gold mineralisation intersected within the targeted felsic intrusion host rock. Importantly, a number of high- grade gold results were returned from the program which are open at depth and along strike.
“This shows the potential of the mineralised system, which is beginning to take shape, pointing to significant future growth opportunities as our drilling programs advance.
“We have now completed over 5,000m since we listed on the ASX in July, with the results from this drilling showing clear potential for shallow open pits at Barimaia.
“Our next step is to complete a diamond drilling program in November to help confirm the orientation, lithologies and geometry of the significant mineralisation centred on section 585,550E. This drilling will be followed up by further extensional and in-fill drilling in the coming months.”
Figure 1. Results from RC drilling at the McNabs East Prospect at Barimaia. September to October 2024 intercepts are highlighted in dark yellow boxes. The location of section lines for Figures 2 to 5 are shown in blue.
Ordell’s exploration at Barimaia is targeting new discoveries of a similar style to the Eridanus deposit, which forms part of Ramelius Resources’ (ASX: RMS) Mount Magnet gold mining operations (Figure 6).
Eridanus lies approximately 6km north-west of Barimaia and hosts a current Mineral Resource Estimate of 21Mt @ 1.7g/t Au for 1,200,000oz of contained gold1, with an additional +300,000 ounces of gold already mined from the open pit.
