Antilles Gold Limited (“Antilles Gold” or the “Company”) (ASX: AAU, OTCQB: ANTMF) is pleased to advise results from the first 7 of 25 shallow diamond drill holes in a 2,000m in-fill program on the Nueva Sabana oxide deposit in central Cuba, which was completed in July 2024.
The aim of the program was to increase the Indicated Resources in the Initial Mineral Resource Estimate advised to ASX on 6 March 2024.
HIGHLIGHTS
Gold Domain – Nueva Sabana
Copper Domain – Nueva Sabana
Sampling Techniques and Data are set out in the JORC Code 2012 Edition Template attached.
NUEVA SABANA GOLD-COPPER MINE
- The in-fill results continue the excellent grades for both gold and copper in the oxide deposit that were incorporated in the Scoping Study for the first stage of the proposed Nueva Sabana gold-copper mine reported to ASX on 7 May 2024.
- Results from the remaining 18 holes are expected by the end of this month.
- An updated Mineral Resource Estimate (“MRE”) for the proposed mine is expected to be completed within two weeks of receiving these results, after which the pit design and mine schedule will be updated, followed by a Pre-Feasibility Study in September 2024.
- The Nueva Sabana oxide deposit is metallurgically simple, and the mine is being planned as a copper project which will benefit from the high-grade gold cap during initial operations.
- Metallurgical test work by Blue Coast Research Laboratories in Canada has indicated a gold recovery of 85% from a simple rougher flotation circuit, and a concentrate of 70.2 g/t Au.
- A copper recovery of 84.5% yielded concentrate grades of 27% Cu from a rougher and cleaner circuit, which has formed the basis of the process design criteria for the Nueva Sabana concentrator.
- Planning and permitting for the proposed mine is well advanced.
- Total development costs are estimated to be ~US$30 million including ~US$5 million of pre- development and concession acquisition costs, and ~US$25 million for mine construction based on quotations for site works, industrial buildings, and a turnkey offer for the design and construction of the concentrator and associated power station.
- The project requires minimal pre-stripping and will not involve the purchase of a mining fleet which is to be hired from the Cuban subsidiary of an international supplier.
- Finance for the mine construction is being negotiated in the form of an advance on concentrate purchases by an international commodities trader.
- The Nueva Sabana project, which is being developed by the 50% owned joint venture company, Minera La Victoria SA, is expected to be development-ready in October 2024.

AAU:AU
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.”

High-Grade Gold Discovery in First 8 Mile Drill Hole
- First RC hole at 8 Mile discovers high-grade gold and ends in mineralisation
- 8 Mile gold mineralisation extends 75m north of tenement boundary
The 8 Mile target is located within the Gidji JV Project (“Gidji” or “the Project”), approximately 15 kilometres north of Kalgoorlie and surrounded by multiple gold mining and processing operations, including Northern Star Resources Limited’s (“NST”) Kalgoorlie gold operations (Figure 1).
The 8 Mile Target is located immediately adjacent to NST’s “8-Mile Dam” gold deposit which, according to the most recent publicly available data, contains an estimated 7Mt @ 1.4g/t Au for 313,977 ounces1.
A limited number of fast-tracked results from the first RC hole, GJRC029, show a wide zone of gold mineralisation with a similar tenor to 8 Mile Dam (18m @ 0.94g/t Au from 480m including 1m @ 6.04g/t Au), approximately 75m north of the tenement boundary, and ended in mineralisation (3m @ 0.52g/t Au).
The Company is awaiting assay results from the remainder of the hole which are expected in 2-3 weeks.
Miramar’s Executive Chairman, Mr Allan Kelly, said the Company was excited to see gold mineralisation continuing onto Miramar’s ground for a significant distance.
“This is the first time we have discovered significant gold mineralisation on our side of the fence, even though the drill hole didn’t end up exactly where we planned it to. The flip side of this is that we have extended the strike of gold mineralisation for over 100m on to our tenements,” he said.
“We’ve also demonstrated a relationship between the IP anomalism and gold mineralisation, which makes the other IP anomalies we have outlined at Gidji even more prospective,” he said.
Figure 1. The Gidji JV Project and 8-Mile Dam in relation to Kalgoorlie and surrounding deposits.
GJRC029 aimed to test an Induced Polarisation (IP) anomaly on the tenement boundary interpreted to represent the sulphide-rich gold mineralisation seen at the neighbouring 8 Mile Dam Deposit.
GJRC029 was collared approximately 10m north of the tenement boundary and mirrored MPGD008, a diamond hole drilled down-dip approximately 40m south of the tenement boundary by KCGM in 2013 and which intersected significant gold mineralisation related to the 8 Mile mafic unit.
Unfortunately, GJRC029 deviated significantly from the planned azimuth and, as a result, by the time the hole was terminated at the target depth of 504m, the drill trace ended up approximately 75m north of the tenement boundary (Figure 2). Despite this, the hole intersected a thick section of the steep westerly- dipping and highly altered 8 Mile mafic unit with widespread sulphide mineralisation, including disseminated magnetite and coarse-grained arsenopyrite, pyrrhotite and chalcopyrite, similar to the 8 Mile Dam Deposit (Figure 3).
Based on visual logging of RC drill chips, handheld portable XRF results and magnetic susceptibility measurements, samples from the bottom 56m of the hole were sent for priority analysis by fire assay at Bureau Veritas in Kalgoorlie.
The results from these initial samples confirm the relationship between the gold mineralisation and sulphides, and a relationship between the best gold mineralisation and coincident magnetic anomalism and elevated Arsenic as measured by handheld portable XRF. The first results also confirm that the IP anomaly is associated with potentially significant gold mineralisation, whilst the significant deviation of GJRC029 away from the planned target increases the potential strike length of gold mineralisation on Miramar’s ground.
Significant results are listed in Table 1, with assay results from the remainder of the hole expected in coming weeks.
The initial RC drilling programme, which also tested two other IP targets, is nearing completion and results will be reported once received and compiled.
Once all assays are received, the Company will plan further RC and/or diamond drill holes including to test the dip and strike extent of the mineralisation intersected in GJRC029.
The Company advises that the WA Department of Mines, Petroleum and Exploration (DMPE) has extended the main Gidji JV tenement, E26/214, for a further five years, and will now expire in March 2030.

Pacgold
Investor Insight
Pacgold is one of Australia’s most compelling gold exploration opportunities, backed by a strong technical team, offering investors exposure to a large-scale, underexplored gold system with significant resource growth potential.
Overview
Pacgold (ASX:PGO) is an Australian gold exploration company focused on the systematic advancement of the Alice River gold project in Northern Queensland. The company is led by a technically driven and highly experienced team of geologists and mining professionals, with demonstrated success in exploration, resource development and capital markets.
Pacgold team on site at Alice River gold project
With a dominant land position in the region, Pacgold holds 377 sq km of exploration permits and eight mining leases across the prospective Alice River Fault Zone (ARFZ). This structure is interpreted as part of a large-scale intrusion-related gold system, with characteristics analogous to major global deposits such as Fort Knox (USA) and Hemi (Western Australia).
The company has validated its model through drilling success at the Central Zone, culminating in a maiden mineral resource of 474,000 oz of gold. This comprises both open pit and underground components, with resource grades averaging 1.2 grams per ton (g/t) gold, and zones open in all directions. Less than five percent of the strike length has been tested, and much of the prospective corridor is obscured by thin sand cover, highlighting strong potential for blind discoveries.
With extensive infrastructure already in place, including an airstrip, accommodation camp and road access within 100 km, Pacgold is positioned to rapidly scale exploration and accelerate resource growth. The 2025 campaign, which includes more than 10,000 metres of RC drilling and new IP surveys, aims to unlock the full regional potential of the ARFZ.
Company Highlights
- District-scale Discovery Potential: Pacgold controls more than 377 sq km of tenure and more than 30 km of strike length across the Alice River Fault Zone (ARFZ), a fertile, underexplored structural corridor in Northern Queensland.

Key Project
Alice River Gold Project
The Alice River gold project is a large-scale, greenstone-hosted gold system centred on the regional ARFZ, located in Northern Queensland. The project area comprises 377 sq km of contiguous tenure, including eight granted mining leases. Pacgold controls over 30 km of strike length along the ARFZ, a major crustal-scale structure that has only recently been systematically explored with modern techniques.
The deposit style is interpreted as an intrusion-related gold system, a highly attractive deposit type known for hosting long-life, large-tonnage gold mines. Examples include the Fort Knox gold mine in Alaska and the Hemi gold project in Western Australia. The Alice River system features sheeted quartz-sulfide veining, extensive sericite-altered zones, and strong IP chargeability responses coincident with surface gold anomalism.
Pacgold’s 2024 and 2025 drilling campaigns have focused on the Central Zone, which yielded the maiden MRE totaling 474,000 oz gold across both open pit and underground resources. The pit-constrained resource includes 10.6 Mt at 1.2 g/t gold (404,000 oz), with a further 1.5 Mt at 1.4 g/t gold (71,000 oz) defined for underground potential. High-grade zones remain open at depth and laterally, with drill spacing still relatively broad (~80 x 80 metres), leaving significant scope for resource expansion.
Beyond the Central Zone, the company has delineated multiple high-priority regional targets along the ARFZ. These include:
- White Lion: A compelling target with surface gold anomalism and a coincident IP chargeability anomaly. A gradient and dipole-dipole IP survey is being extended in Q2 2025, with drilling expected in Q4.
- Victoria and The Shadows: Emerging prospects to the south with limited historical drilling but strong geophysical responses.
- Posie and Southern Target Area: Additional areas along the southern ARFZ strike that exhibit strong structural preparation, geochemical responses and potential for concealed mineralization.
Drilling recommenced in April 2025, with RC drilling underway and air-core and diamond drilling scheduled through Q3 2025. The program aims to increase drill density in resource zones and test underexplored regional anomalies. Pacgold expects up to 15,000 metres of total drilling during the 2025 campaign, coupled with ongoing geophysical targeting, including IP and drone magnetics.
The project is fully permitted, with strong access and logistics, and is located in a low-risk jurisdiction with significant precedent for gold development. With limited historical exploration and clear mineralizing controls now defined, Alice River represents a transformative opportunity to uncover a Tier 1 discovery in an overlooked Australian belt.
