High Grade Gold And Copper Assays Continue At El Pilar Oxide Deposit, Cuba
Antilles Gold Limited (“Antilles Gold” or the “Company”) (ASX Code: AAU, OTCQB: ANTMF, FSE Code: PTJ) is pleased to provide assays from the latest cored drill holes into the El Pilar oxide deposit in central Cuba which, together with previously reported results, reinforce the prospect of developing the proposed Nueva Sabana gold-copper mine.
EL PILAR OXIDE CONCESSION (752 ha)
- The current 7,000m program, together with 1,800m drilled last year, and 24,000m of historic drilling are aimed at establishing the Mineral Resource Estimate ("MRE") for the Nueva Sabana mine for the production of gold, and copper-gold concentrates.
- A total of 24 holes (3,701m) have been drilled by the Company to date, and assays from the latest 5 holes are included in this announcement.
- The collective results support the concept of developing a low cap-ex open pit mine to establish an early cash flow.
HIGHLIGHTS FROM 24 CORED DRILL HOLES
Gold Domain
Copper Domain
Sampling Techniques and Data are set out in the JORC Code 2012 Edition Template attached.
- The gold zones within in the El Pilar oxide deposit are well defined, and the copper zones are increasing in volume both laterally and vertically with continuing exploration, and are expected to project into the underlying porphyry sulphides.
- Metallurgical test work by Blue Coast Research Laboratories in Vancouver has indicated a gold recovery of 85% from a simple rougher flotation circuit, and a concentrate grade of 53.1g/t Au from a 2.11g/t Au head grade.
The development of the Nueva Sabana mine for the El Pilar oxide deposit will benefit from the following;
- Minesite adjacent to HT power mains, water supply, and rail and highway access to the port of Mariel for export of concentrates.
- Flat, unoccupied site close to towns for sourcing workers.
- Resultant low infrastructure costs.
- Initial production of readily saleable gold concentrate from the upper ~50m gold domain.
- Production of in-demand copper-gold concentrate to follow from the lower copper domain, and possibly the underlying copper porphyry halo.
- Flotation circuit achieving excellent recoveries for both gold and copper in current metallurgical test work.
- Mining equipment available from international supplier on a dry-hire basis.
- Estimated development cost of less than US$20 million likely to be financed by concentrate buyer.
- Project could be development ready March 2024, and constructed at the same time as the proposed La Demajagua gold, antimony, silver mine.
The costs of drilling, and other pre-development activities for the proposed Nueva Sabana mine will be credited as part of a US$1.5 million loan from Antilles Gold to the joint venture company, Minera La Victoria SA, which intends to develop the mine.
A US$1.5 million loan has also been provided to Minera La Victoria by the Cuban Government's mining company, GeoMinera SA, resulting from its transfer of the El Pilar oxide concession to the 50:50 joint venture for this amount.
Mr Brian Johnson, Executive Chairman of Antilles Gold, said that the Company would produce an Exploration Target Range for the oxide deposit as soon as possible to provide an indication of the potential size of the Nueva Sabana project, in advance of establishing the MRE.

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.

Spartan Managing Director and CEO, Mr Simon Lawson, commented:
“It’s been another huge quarter for Spartan, with a new high-grade gold discovery at the Pepper Prospect, further outstanding intercepts from across our existing deposits – including our deepest project assay to date from Never Never, which graded almost eight grams per tonne more than 1km down-hole – and a landmark $80 million capital raising that will enable us to substantially ramp-up exploration and development activities.
“Our drilling throughout the Quarter has continued to reinforce our ability to deliver high-grade ounces in front of Dalgaranga’s existing infrastructure.
“The new Pepper discovery has provided plenty of excitement for our geology team, delivering a new zone of high-grade Never Never-style mineralisation in between the existing Never Never and Four Pillars deposits, with the discovery hole returning an intercept of 17.52m grading 15.86g/t gold, including 9.22m grading 27.89g/t.
“Since first announcing the discovery in mid-April, we have had a drill rig continuously turning at Pepper, with the Company on-track to deliver a maiden Mineral Resource Estimate for the deposit as part of our scheduled mid-year Resource update for Dalgaranga. This Resource update will also include inaugural estimates for the Four Pillars and West Winds deposits, as well as updates for both Never Never and Sly Fox.
“All of the drill results reported during the Quarter were returned from steeply-dipping deposits along a single, 800m-long stratigraphic horizon, with planning now complete for the development of an exploration drill drive to provide underground drill platforms to better target this zone. We expect to be in a position to commence construction of this drill drive during the September Quarter, positioning the Company for plenty of exciting drilling in the second half of the year.
“Development of this drill drive, as well as our ongoing exploration and development programs, will be underpinned by the highly successful $80 million capital raising completed during the Quarter. This raising was well supported both by institutional and retail investors and I would like to sincerely thank all shareholders who participated.”

Rich Checkan: Gold Still "Dirt Cheap" at All-time Highs, Buy Now if You Haven't
The gold price remains historically high, but for Rich Checkan, president and CEO of Asset Strategies International, the yellow metal is still "dirt cheap."
He urged those who haven't made allocations to gold and silver yet to consider buying now.
"We're heading into the doldrums, we're kind of consolidating here. China's off the market ... so the prices are low here — at all time-highs, the prices are low. And because western investors aren't buying coins and bars, the premiums are low," Checkan explained. "You've got the perfect storm here of low prices, low premiums — take advantage of it."

Dana Samuelson: Never More Bullish on Gold, Silver Can Easily Break Higher
Dana Samuelson of American Gold Exchange discussed his outlook for gold and silver prices in both the short and long term, and mentioned which physical products he recommends investors look into.
"I wouldn't be surprised to see silver make a US$5 or US$10 move from here very quickly, especially if gold can break a little above its all-time high," he explained on the sidelines of the the Rule Symposium.
He was speaking a week before gold did exactly that. Samuelson added, "If gold makes a run at a new high and gets into the US$2,500 (per ounce) range, I think silver could be US$45, US$50 (per ounce) very quickly."

New drill drive to provide underground drill platforms to in-fill and extend existing deposits and identify new high-grade shoots
Spartan Resources Limited (“Spartan” or “Company”) (ASX: SPR) is pleased to announce that it has awarded the contract for the development of an underground exploration drill drive at its 100%-owned Dalgaranga Gold Project (“DGP”), located in the Murchison region of Western Australia, to specialist underground mining services contractor, Barminco Limited, a wholly owned subsidiary of the ASX-listed global diversified mining services company Perenti Limited (ASX: PRN).
Highlights:
- Development contract for the underground exploration drill drive at the Dalgaranga Gold Project awarded to Barminco Limited.
- The contract, which is valued at ~$18.3 million, provides for 2,350m of development to deliver twin decline access for the establishment of underground drilling platforms to in- fill and extend mineralisation within the Never Never, Pepper, Four Pillars and West Winds areas.
- The drill drive has also been designed to support future mine production activities.
- All regulatory mining approvals are now in place and all major support services have been engaged to facilitate the commencement of construction in the current quarter.
- Surface exploration drilling at Dalgaranga will shortly re-commence, with rigs arriving on site later this month.

The contract, which is valued at ~$18.3 million including an allowance for fuel and contingencies, provides for 2,350m of development to deliver twin decline access for the establishment of underground drilling platforms to in-fill and extend mineralisation across the Never Never, Pepper, Four Pillars and West Winds deposits.
All of these steeply-plunging, high-grade gold zones are located along a single 800m-long, semi- continuously mineralised north-south stratigraphic horizon (see Figure 1). The exploration drill drive has been designed to run parallel and adjacent to this horizon to provide underground drill platforms to more effectively define these existing deposits and prospects, as well as explore for further high-grade shoots and provide critical underground infrastructure as Spartan develops its future mine plan.
Construction of the drill drive is on-track to commence in the September Quarter, with all regulatory mining approvals and support services in place. In addition, the Company has established an experienced on- site project team to manage and oversee the development and construction process. Establishment of the drill drive, and an initial underground drilling programme, is fully funded from the Company’s existing cash reserves.
Management Comment
Spartan Managing Director and Chief Executive Officer, Simon Lawson, said: “We are delighted to have Barminco on board to complete the construction of this new drill drive, which represents a very exciting initiative that will enable us to drill from platforms located right alongside our high-grade deposits and targets. This will provide for cheaper, more accurate and quicker drilling to continue to accelerate our Resource growth and conversion to Ore Reserves.
“All of the high-grade deposits and prospects discovered at Dalgaranga over the past two years remain open at depth – with mineralisation at the Never Never deposit now defined to beyond 1km below surface – and we’re very excited to get the underground rigs in place to help determine just how deep this high- grade mineralisation extends.
“Importantly, the drill drive is being constructed using the same dimensions as a standard underground mine development, ensuring it can be incorporated into our infrastructure planning for the future re- commencement of mining operations.
“Construction of the drill drive is set to kick-off later this Quarter and is expected to take approximately 10 months to complete. In addition, we will also shortly re-commence surface drilling programs, targeting the Pepper, Four Pillars, West Winds and other near-surface anomalies, ensuring plenty of exciting news- flow for shareholders in the months ahead.”

Boundiali Preliminary Metallurgical Test Work Delivers Gold Recoveries up to 99%
Highlights
- Excellent Gold Recovery: Bottle roll tests on 50 samples from BDT1 confirm gold mineralization is free milling, with cyanide leach recoveries consistently exceeding 93% for samples grading 0.25 g/t gold or higher
- Oxidized Ore Excels: Oxide samples exhibit exceptional gold recoveries, averaging 97.5% and reaching a maximum of 99%
- Consistent with Expectations: The metallurgical response aligns with typical free-milling ores found in similar deposits
- Further Testing Planned: Additional metallurgical work will be conducted to establish and optimise processing flowsheets
- Well-Funded: Aurum received firm commitments for a $17M Share Placement in June with Shareholders to vote on Tranche 2 on 6 August 2024
Aurum’s Managing Director Dr. Caigen Wang said: “Preliminary gold recoveries meet our expectations and confirm gold at BDT1 is highly amenable to standard cyanide leaching. While further work is needed, these are very encouraging results.
We are well funded following a recent Share Placement and Share Purchase Plan and rapidly expanding our drilling program at Boundiali. We will have six Aurum-owned diamond rigs running from the end of August as we target delivery of an initial JORC resource for Boundiali by the end of 2024.”
Metallurgical Test Work Summary
Preliminary test work involved 50 coarse reject samples from various depths, lithologies, and oxidation states at BDT1. Samples were prepared and analysed by Intertek laboratories in Ghana.
These samples were selected from a representative range of gold grades (likely to be encountered in an open pit), lithologies and oxidation states. Samples were selected from diamond core holes drilled by Aurum at BDT1 this year and cover a subset of that prospect over a volume bounded by 300m (east to west) and 550m (south to north) and down to 328m below surface (average depth of 106m below surface).
Preparation and analysis of the samples was undertaken by Intertek laboratories in Ghana. Samples were pulverized to 85% passing 75-micron (85% of the particles are smaller than 75 microns) and then subjected to a bottle roll cyanide leach for 24 hours using the cyanide (CL1000/AA) technique with an analysis on the leach liquor to measure the leach gold grade. The residue was then filtered and analysed by 50g fire assay (FA50T/AA) to show the remaining gold (tail grade). The sum of the leach grade and the tail grade represents the calculated head grade of the original sample (total gold). The calculated gold recovery is estimated by dividing the leach grade by the total gold grade.
