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.

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.”

Horizon Minerals
Investor Insight
Horizon Minerals’ near-term cash-flow potential and its significant land package in the prolific Western Australian goldfields with considerable exploration upside position the company to positively leverage the current bull gold market opportunity.
Overview
Horizon Minerals (ASX:HRZ) is an ASX-listed emerging mid-tier gold mining company focusing on a portfolio of highly promising gold projects located in the world-class Western Australian goldfields. The recent merger with Greenstone has added nearly 0.5 million ounces (Moz) of high-grade resource to Horizon, taking its total tally to 1.8 Moz, and resulted in Horizon Minerals total land package of 939 sq km in the Kalgoorlie-Coolgardie district.
The Greenstone merger brings near-term cash-generating opportunities and adds greater scale to its baseload assets (Boorara) with the high-grade Burbanks deposit. Horizon’s dual-track strategy involves generating immediate cash flows by leveraging a pipeline of development-ready production assets and concurrently advancing the cornerstone assets, Boorara and Burbanks, which have a combined resource inventory of 914 koz at 1.7 grams per ton (g/t) gold with potential to support a profitable, long-life operation.
The recent ore sale agreement with Paddington Gold is encouraging and increases confidence in the management’s ability to generate near-term cash flows. Under the agreement, 1.4 million (Mt) will be processed over a period of 22 months. The agreement allows Horizon to capitalize on high gold prices to generate significant cash flows.
Horizon is also progressing with other projects, including the Cannon gold project and Penny’s Find underground mine, and actively exploring for new discoveries in the Western Australian Goldfields, targeting gold and other commodities such as nickel-cobalt, silver-zinc, PGEs and lithium across its extensive land holdings. Additionally, Horizon holds a significant stake in one of the world’s largest vanadium projects via its investment in Richmond Vanadium Technology, which is listed on the ASX.
Horizon proposes to acquire 100 percent of Poseidon via an all-scrip transaction for AU$30 million to consolidate 1.8Moz gold and highly strategic processing infrastructure for Horizon to transition to the next standalone WA gold producer. The acquisition will combine Horizon’s large gold resource and Poseidon’s Black Swan processing infrastructure in the Kalgoorlie-Coolgardie districts. The transaction will further result in substantial resource base and regional tenure to a combined JORC mineral resources of ~1.8Moz gold at an average grade of 1.84g/t gold and 422,700t nickel at an average grade of 1 percent nickel. Horizon and Poseidon will have a total of 1,309 sq. km. tenure in an attractive geological position in the WA Goldfields.
Horizon aims to become a sustainable, 100kozpa standalone producer following the merger and conversion and recommissioning of the Black Swan processing plant. The 2.2Mtpa processing facility is strategically located 40 km north of Kalgoorlie with a concentrator readily amenable to processing gold through cost-effective refurbishment and the addition of a new CIL circuit.
Horizon's 30Mt existing gold resources, with 50,000 metres of drilling fully funded to commence drilling in 2025 or 2026, strongly support the conversion of the Black Swan processing plant to a gold plant.
Company Highlights
- Horizon Minerals is an emerging mid-tier gold producer with an extensive portfolio of highly promising gold projects located in the world-class Western Australian goldfields.
- The recently completed merger with Greenstone Resources positions Horizon as a mid-tier gold producer in the Western Australian Goldfields. The combined entity enhanced Horizon’s portfolio with two complementary cornerstone gold assets — Burbanks and Boorara (combined resource of 914,000 oz).
- Mineral resource updates after the merger include 1.8Moz gold, 20.2Moz silver, 104kt zinc, 283kt nickel, 40.5kt cobalt and 296.2kt manganese.
- Changes to the gold MREs include:
- Addition of 297,650oz from Burbanks open pit
- Addition of 167,920oz from Burbanks underground
- Addition of 13,000oz from Pinner
- Addition of 3,000oz from Monument
- Reduction of 20,240oz from Boorara
- Horizon has announced a proposed merger with Poseidon Nickel Limited with Horizon having in ground gold assets that can be processed, and Poseidon having processing facilities including the Black Swan plant, which Horizon proposed to refurbish and repurpose from a concentrator into a gold CIL plant.
- Open pit mining has commenced at the Boorara gold project in August 2024 and the first ore was exposed and mined in late September 2024, with first ore being delivered to the Paddington mill for processing.
- Horizon also recently commenced mining at its recently acquired Phillips Find project with ore to be processed at the Greenfields mill near Coolgardie from February to June 2025.
- Horizon is also progressing with other projects, including the Cannon and Penny’s Find underground mines.
- Amidst the current record gold prices, Horizon seeks to capitalize on this opportunity by advancing its substantial resource endowment towards development, thereby generating cash flow.
Key Projects
Boorara Gold Project
The Boorara gold project is located 15 km east of Kalgoorlie-Boulder in the Western Australian goldfields. Over the past decade, a substantial amount of reverse circulation and diamond drilling has been carried out at Boorara. The project includes a JORC 2012 mineral resource estimate (MRE) by Optiro (now Snowden Optiro), which reported a total of 10.53 Mt grading at 1.26 g/t gold, amounting to 448,000 ounces.
The company views Boorara as a substantial baseload feed source that could be enhanced by lower tonnage, higher-grade feed to sustain a standalone milling facility. This is where the recent acquisition of Greenstone becomes important. Boorara can be supplemented by higher-grade feed from Greenstone’s Burbanks deposit to support an integrated operation.
The Independent JORC (2012) Ore Reserve for Boorara, completed by AMC Consultants, shows a financially viable project highlighted by an open pit mine design producing 1.24 Mt at a fully diluted grade of 1.24 g/t gold for 49.5 koz over an approximate 14-month mine life, and ore sale agreement at 92.5 percent metallurgical recovery produces 45.8 koz recovered.
Boorara commenced open pit mining in August 2024, with the first ore exposed and mined in late September 2024. Mining at the site will occur over 14 months and processing over 19 months at Norton Gold Fields’ Paddington plant to generate $30 million in estimated free cashflow at a AU$3,600/oz gold price.
Phillips Find Gold Project
The Phillips Find gold project is located 45 km north-west of Coolgaride, Western Australia in the heart of the Western Australian goldfields covering 10 kilometres of strike over prospective greenstone stratigraphy. The project includes the Phillips Find Mining Centre (PFMC) where approximately 33,000 ounces of gold were produced between 1998. A joint venture (JV) agreement is in place with mining specialists BML Ventures Pty Limited (BML) to develop and mine two open pits at Phillips Find. Horizon Minerals plans to commence the grade control program early in December and the first mining of ore in December 2024. The first ore from Phillips Find is on track to be treated at FMR’s Greenfields mill from February 2025 to June 2025
Nimbus Silver-Zinc Project
The 100 percent owned Nimbus silver-zinc-lead-gold deposit is located 15 kilometres east of Kalgoorlie-Boulder in Western Australia within the Kalgoorlie Terrane. The project's current mineral resource estimate (JORC 2012) includes 12.1 million tons at 52 g/t silver, 0.2 g/t gold and 0.9 percent zinc containing 20.2 million oz of silver, 78,000 oz of gold and 104,000 tons of zinc using lower cut-off grades of 12 ppm for silver, 0.5 percent for zinc and 0.3 g/t for gold over a 2 metre down hole composite. Within this global resource, the Nimbus project has a high-grade silver and zinc resource of 255,898 tons at 773 g/t silver and 13 percent zinc.
A concept study has confirmed the optimal economic development pathway by mining the higher-grade lodes and generation of a silver/zinc concentrate. A programme of work (POW) has been approved and drilling to test the exploration target is expected to be undertaken in the first half of 2025. The Nimbus project is 2 km east of Horizon's cornerstone Boorara project and 6.5 km north-northwest of Golden Ridge, both historic gold mining centres.
Burbanks Gold Project
The Burbanks gold project is situated 9 km southeast of Coolgardie, Western Australia. The project encompasses the Burbanks Mining Centre and more than 5 kilometers of the highly promising Burbanks Shear Zone, historically the most significant gold-producing structure within the Coolgardie Goldfield. Previous underground production at Burbanks has surpassed 420,000 oz to date.
Burbanks currently hosts a total resource of 6.1 Mt @ 2.4 g/t gold for 466 koz, including underground of 1.2 Mt @ 4.4 g/t gold for 168 koz. Burbanks is underexplored and remains open in all directions for future growth.
Cannon Underground Project
The Cannon gold project is located 30 km east-southeast of Kalgoorlie-Boulder. It is a fully permitted project with a pre-feasibility study completed in 2022, which shows strong project economics with a free cash flow of AU$10.1 million over the mine's life. The company has finished commissioning a dewatering pipeline and a pumping system, representing a major milestone in the advancement of its Cannon Underground project. Discussions with mining contractors and potential JV mining partners are underway. First ore production from the Cannon Project is expected to commence in Q4 2024.
Penny’s Find
Penny’s Find is about 50 km northeast of Kalgoorlie in the Eastern Goldfields of Western Australia, near the company’s wholly-owned Kalpini gold project. It comprises a granted mining lease and other associated leases covering 91 hectares. The mineral resource estimate updated in December 2023 boasts 63,000 ounces of gold in the indicated and inferred category. A pre-feasibility study for exploitation using underground mining methods is currently underway. This study will include mine design and financial analysis.
