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.”

Sun Summit Minerals
Investor Insight
Sun Summit Minerals is targeting the delineation of a multi-million-ounce gold-silver resource at its flagship JD project. With strategic positioning in an emerging consolidation hotspot, compelling valuation metrics, and a track record of discovery, Sun Summit is primed to deliver substantial value creation in the coming quarters.
Overview
Sun Summit Minerals (TSXV:SMN,OTCQB:SMREF) is a Canadian mineral exploration company focused on developing its district-scale gold and copper projects in British Columbia. The company’s flagship JD Project, located in the Toodoggone district, is undergoing an aggressive 5,000-meter drill campaign in 2025 aimed at delineating a multi-million-ounce epithermal gold-silver system.
Complementing JD is the company’s Buck project, a large, bulk-tonnage gold-silver system near Houston, BC, with an initial NI 43-101 resource estimate and significant exploration upside.
With capital in hand, a five-year exploration permit secured, and a camp established at JD, Sun Summit is executing a focused strategy to build scale, unlock resource potential and drive shareholder value. The company has taken lessons from its past and re-emerged with a sharpened vision, an overhauled team and assets that are not only high-grade but strategically located to create shareholder value.
Company Highlights
- Aggressive Discovery Strategy: Sun Summit Minerals is actively advancing the JD and Buck projects in BC, targeting epithermal gold-silver and porphyry copper-gold systems. A fully funded 5,000-meter drill program at JD underway in 2025, aiming to define a multi-million-ounce resource.
- Strategic Location: Both assets are situated in prolific and mining-friendly regions of British Columbia. The flagship JD project lies in the Toodoggone district—home to Thesis Gold and Centerra’s Kemess Mine, while Buck is near the Blackwater, Huckleberry, and Equity Silver mines in central BC.
- Re-rate Potential Opportunity: Trading at just ~$7/oz gold equivalent (EV/oz) based on Buck alone, with no value currently ascribed to JD, the company represents a deep value opportunity compared to the next-door neighbour Thesis Gold trading at ~$50/oz. Success at the drill bit from the ongoing drill program at JD could drive the potential re-rating.
- Fully Funded for 2025: A recent C$10M raise (May 2025) enables a robust exploration program, including drilling, geophysics, and soil sampling. The company is well-positioned to achieve its 2025 and 2026 exploration milestones without further dilution.
- Experienced, Capital Markets-Savvy Leadership: CEO Niel Marotta brings capital markets acumen from Fidelity and Orezone. The broader team includes senior geologists and advisors with decades of success in gold discoveries and mine development in BC.
- Positioned for Consolidation: With majors like Freeport, Centerra, and Skeena investing heavily in adjacent properties, Sun Summit is strategically located and advancing at the right time in the Lassonde Curve to benefit from industry-wide M&A and consolidation trends.
Key Projects
JD & Theory Projects
The JD & Theory projects span more than 25,000 hectares in the heart of the Toodoggone mining district in north-central BC, one of Canada’s most prospective belts for epithermal gold-silver and porphyry copper-gold systems. The district is home to Thesis Gold’s Ranch and Lawyers deposits (4.7 Moz gold equivalent, C$250 million market cap), Centerra’s Kemess underground development, and TDG Gold’s Shasta-Baker project. Infrastructure around the project includes hydroelectric grid access, the nearby Sturdee airstrip and all-season roads.
The JD project hosts a 4.5 km mineralized corridor, known as Creek-Finn, with multiple underexplored targets showing evidence of both high-grade veins and broad disseminated gold systems. Historic and recent drill highlights include:
- 2.1 grams per ton (g/t) gold over 122.5 m including 121 g/t gold over 1.5 m (CZ-24-004)
- 11.7 g/t gold over 22 m including 61.2 g/t gold over 4 m (CZ97-008)
- 7.3 g/t gold over 35.7 m including 215.4 g/t gold over 1 m (JD95-0472)
The Creek Zone features high-grade epithermal veins within broader disseminated zones, supported by strong IP anomalies and gold-in-soil results up to 12.2 g/t gold. The Finn Zone hosts near-surface mineralization with extensive historical drilling (~270 holes) and is open in all directions. Other targets include McClair (porphyry copper), East McClair (copper-gold skarn) and Moosehorn.
The 2025 program includes 5,000 meters of core drilling across 25 holes, 20 km of IP geophysics, 2,000+ soil samples, and full-scale camp operations. A five-year permit secured in April 2025 provides exploration continuity through 2030.
Camp setup at JD project
Sun Summit can earn 100 percent of the JD project by making staged cash/share payments and completing work commitments through 2029. With ~C$6 million earmarked for the project this year alone, Sun Summit is expected to fulfill its 2025 and 2026 earn-in obligations without additional equity raises.
Buck Project
The 100 percent owned Buck project spans 52,000 hectares and is located near key deposits, including Artemis Gold’s Blackwater (8 Moz gold), Imperial’s Huckleberry copper mine, and Newmont’s historic Equity Silver mine. Buck features near-surface bulk-tonnage gold-silver mineralization with porphyry copper-molybdenum potential at depth.
In February 2025, Sun Summit published its inaugural NI 43-101 mineral resource:
- Indicated: 1.15 Mt @ 0.519 g/t gold equivalent (19,100 oz)
- Inferred: 52.2 Mt @ 0.489 g/t gold equivalent (820,400 oz)
Mineralization remains open in all directions. Buck is considered a strategic asset providing leverage to rising gold prices and future transaction potential, but currently receives minimal capital allocation as JD is prioritized.

Overview
Aurum Resources (ASX:AUE) is a mineral exploration company primarily focused on gold through its Boundiali and Napié gold projects in Côte d’Ivoire, West Africa.
Côte d'Ivoire's gold mining sector is experiencing significant growth and development, with several key projects contributing to the country's economic expansion. The overall gold mining sector in Côte d'Ivoire is supported by substantial investments in infrastructure and exploration.
Geopolitically, Côte d'Ivoire outperforms most developing countries in the world in political, legal, tax and operational risk metrics. Additionally, Côte d'Ivoire continues to make notable strides in its political stability and Absence of Violence and Terrorism Index.
Boundiali Gold Project – BD Target 1 Artisanal Working
Aurum has entered into a Bid Implementation Agreement with Mako Gold for Aurum to acquire 100 percent of the issued shares in Mako. This proposed merger will allow both Aurum and Mako security holders to benefit from the combination of Aurum’s strong balance sheet and exceptional drilling efficiencies with AU$23 million in cash at the end of December 2024 to support work programs targeted at further resource definition across Aurum and Mako’s assets in northern Côte d'Ivoire. Aurum is currently in its final phase of compulsory acquisition of remaining Mako shares after it received over 90 percent acceptance of MKG shares in late January 2025.
Following its takeover of Mako Gold, Aurum holds 90 percent of the Napié Project located 30 km southeast of the city of Korhogo and covers a strike length of 30 km over a highly prospective land package of 224 sq km.
The merger is backed by a highly experienced board and management team with extensive gold experience from grassroots discovery, through to resource drill-out, feasibility studies, project finance, and production.
With a strong financial position backed by the recent $35.6 million private placement, Aurum is well-funded to execute exploration and development plans focused on delivering value for shareholders through resource growth and project advancement.
Company Highlights
- Aurum Resources is a precious metals company with exploration prospects in the same greenstone belt as the Syama (11.5 Moz), Sissingué (1.0 Moz), Tongon (5.0 Moz) and Kone Gold (4.5 Moz) deposits of West Africa.
- A total of 2.5Moz gold resource in Côte d'Ivoire, West Africa:
- Boundiali - 1.6Moz Gold Project
- Napié - 0.87Moz Gold Project
- Aurum operates its own drill rigs, allowing the company to significantly reduce its exploration costs relative to peers.
- Management has a track record of creating value for shareholders from exploration through to project development, mine construction and gold production.
- Strong leverage to increasing gold prices that will benefit from a declining interest rate environment and rising global geopolitical risk factors.
- Well-funded for more than 12 months and over 100,000 metres of diamond drilling programs and metallurgical study
- Aurum’s acquisition of 100 percent of Mako Gold’s issued shares (ASX:MKG) is in its final stage of compulsory acquisition of the remaining MKG shares after Aurum received over 90 percent acceptance in late January 2025.
Key Projects
Boundali Gold Project
The Boundiali gold project in Cote d’Ivoire is located within the Boundiali Greenstone Belt, which hosts Resolute’s Syama gold operation (11.5 Moz) and the Tabakoroni deposit (1 Moz) in Mali. Neighbouring assets also include Barrick’s Tongon mine (5 Moz) and Montage Gold’s Kone project (4.5 Moz).
The Boundiali project area covers the underexplored southern extension of the Boundiali belt, where a highly deformed synclinal greenstone horizon traverses finer-grained basin sediments, and to the west, Tarkwaian clastic rocks lie in contact with a granitic margin. The project benefits from year-round road access and excellent infrastructure.
The first stage of drilling at Boundiali occurred from late October 2023 to end of November 2024 for both the BM and BD tenements (BM1 and BM2; BD1, BD2 and BD3 targets) and was designed to test below-gold-in-soil anomalies oriented along NE trending structures, define new gold prospects and define maiden JORC resources. With over 63,000m diamond holes drilled during this period, Maiden JORC gold resources estimate was delivered in late December 2024.
Drilling costs are estimated at US$45 per metre, as Aurum owns all of its eight drilling rigs and employs its operators, representing a significant value proposition relative to peers who use commercial drilling companies that charge upwards of $200 per meter. The company believes there is potential for multi-million ounce gold resources to be defined with hundreds thousands meters of drilling over years within the Boundiali Gold Project’s land holding areas.
The Boundiali gold project comprises four contiguous granted licenses: PR0808 (80 percent interest), PR0893 (80 percent and earning to 88 percent interest), PR414 (100 percent interest), and PR283 (earning to 70 percent interest). Historic exploration at PR0893 includes 93 AC drill holes and four RC holes. Airborne geophysical surveying, geological mapping and extensive soil sampling have also been performed at PR0893, while PR0808 has had 91 RC holes drilled for 6,229 metres along with geochemical analysis and modeling. Detailed geochemical sampling and drilling at PR414 revealed three strong gold anomalies and returned impressive high-grade results.
Following the renewal of its Boundali South (BST) exploration licence in September 2024, drilling at the Nyangboue deposit is planned for H1 2025 and H2 2025. Previous exploration at BST has returned impressive results, including 20 m at 10.45 g/t gold from 38 meters, and 30 m at 8.30 g/t gold from 39 m.
In May 2024, Aurum entered a strategic partnership agreement to earn up to a 70 percent interest in exploration tenement PR283, to be renamed Boundiali North (BN). Aurum, through subsidiary Plusor Global Pty Ltd, has partnered with Ivorian company Geb & Nut Resources Sarl and related party (GNRR) to explore and develop the Boundiali North (BN) tenement which covers 208.87sq km immediately north of Aurum’s BD tenement. Further to this agreement,
Aurum announced it has earned 80 percent project interest after completing more than 20,000 m of diamond core drilling.
Boundiali Project JORC Mineral Resource Estimate
Aurum has announced a maiden independent JORC mineral resource estimate of 1.59 Moz gold for its 1,037 sq. km. The Boundiali Gold Project comprises the BST, BDT1 & BDT2, BMT1 and BMT3 deposits. Drilling is ongoing on these deposits, and Aurum has identified other prospects at Boundiali which have yet to be drilled. Since October 2023, the company has completed an extensive 63,927-metre diamond drilling program. This aggressive exploration campaign has rapidly defined a significant gold resource of 50.9 Mt @ 1.0 g/t gold for 1.6 million ounces.
Growth Plans for the Boundali Project:
- Aggressive cost-effective exploration at Boundiali: Aurum is committed to a large-scale exploration program at Boundiali. This includes:
- 100,000 m diamond drilling: Up to eight diamond drill rigs will complete 100,000m of drilling at Boundiali in 2025. The program has multiple aims:
- Increase the size and confidence of current resources at BST, BD, and BM (40,000m).
- Advance known prospects (30,000m) for incorporation into two planned MRE updates in 2025.
- Target new prospects identified through soil anomalies and geological mapping to drive resource growth into 2026 (30,000m).
- Resource expansion: Drilling aims to expand the known resources at the BST, BD, and BM deposits.
- New discoveries: Exploration and scout drilling is planned on BD, BM and BST tenements to test new targets and create a pipeline of new discoveries to flow into resource growth.
- Boundiali resource updates: Aurum plans to deliver two MRE updates for Boundiali in 2025.
- Pre-Feasibility Study: Aurum is working towards completing an open pit PFS for the Boundiali Gold Project by the end of 2025. This will provide an evaluation of the project's economics and technical feasibility.
- 100,000 m diamond drilling: Up to eight diamond drill rigs will complete 100,000m of drilling at Boundiali in 2025. The program has multiple aims:
Napié Gold Project
Aurum holds a 90 percent interest in the Napié Project in north-central Côte d’Ivoire, acquired through its takeover of Mako Gold. Located approximately 30 km southeast of Korhogo, the project covers a 224 sq km land package with a 30 km strike length along the highly prospective Napié Shear Zone.
As of June 2022, Napié hosts a JORC 2012 Mineral Resource Estimate of 868,000 ounces of gold (22.5 Mt at 1.20 g/t Au), based on the Tchaga and Gogbala deposits—two of four known prospects along the shear. To date, only 13% of the Napié Shear has been explored, leaving substantial potential for further discoveries.
Napié Project – Previous results with detailed mapping area on Komboro Prospect shown in black rectangle
Project Highlights:
- Gold Resource: Shallow open pit 0.87Moz JORC Resource at 1.20g/t Au, with mineralisation open along strike and at depth. Maximum resource depth between 160 m – 195m across the two deposits
- Exploration Upside: Less than 13 percent of the 30 km Napié Shear has been explored, offering significant potential for resource growth.
- Drilling Commenced in June 2025: 30,000 m of diamond drilling has commenced to expand the project's resource.
- Preliminary Recovery Test Work: Returned more than 94 percent average gold recoveries.
- Resource Growth Target: First MRE update planned end of 2025, to significantly expand the resource base.
- Infrastructure: Excellent access to hydroelectricity, roads, and water, supporting future development.
