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.”

Sitka Intersects Multiple Occurrences of Visible Gold from near Surface in Initial Six Diamond Drill Holes Completed at the Contact Zone, RC Gold Project, Yukon
Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) ("Sitka" or the "Company") is pleased to announce that multiple occurrences of visible gold have been observed, beginning near surface, in the first six drill holes to be completed by the Company at the Contact zone. Visible gold has now been observed in the drill core from every target that has been drilled within the Clear Creek Intrusive Complex so far this year, including Blackjack, Saddle, Eiger and Rhosgobel. Up to 5,000 metres of drilling is currently underway at the Contact-Pukelman zone (see Figures 3, 4 and 6) as part of the fully funded 30,000 metre diamond drill program currently underway at Sitka's 100% owned, road accessible RC Gold Project located in the Yukon's prolific Tombstone Gold Belt. Over 25,000 metres of drilling has been completed at RC Gold this year where drilling has focused on growing the Blackjack and Eiger deposits, expanding the mineralized footprint of the Saddle zone, and testing the potential of the Rhosgobel, Contact-Pukelman and Bear Paw targets to host additional intrusion-related gold deposits. Four drill rigs are currently operating on the Project with two rigs at Pukelman, one rig at Rhosgobel and one rig at Bear Paw (see Figure 6) with assay results currently pending for 52 holes.
- Visible gold observed in first six diamond drill holes drilled at the Contact zone
- Drilling to date has traced mineralization along a strike of approximately 900 m and to a depth of approximately 430 m from surface at the Contact zone
- Visible gold has now been observed in drill core from all five targets drilled within the Clear Creek Intrusive Complex this year
- First drilling completed since 2010/2011 that produced historical intersections in Contact zone of 38.3 m of 1.54 g/t gold, 74.3 m of 1.01 g/t gold and 43.4 m of 1.20 g/t gold in Holes CC11-043, 044, 045 respectively and 10.7 m of 20.46 g/t gold in CC10-22
- Six holes totalling 2,172 m completed as part of the ongoing 5,000 m of drilling planned at Contact-Pukelman target
- Drilling has also recently commenced at the Bear Paw target
- Results are currently pending for all holes drilled at Contact-Pukelman along with holes completed across Blackjack, Saddle, Eiger, Rhosgobel and Bear Paw
- Over 25,000 metres of the ongoing 30,000 m planned drill program completed with assays currently pending for 52 holes
"The Contact zone is now the fifth target drilled by Sitka Gold in 2025 to yield multiple occurrences of visible gold within the core of the Clear Creek Intrusive Complex," said Cor Coe, CEO and Director of Sitka Gold. "The widespread and robust gold mineralization being intersected in our drilling across this area continues to demonstrate that the RC Gold project is a unique gold camp with multiple intrusions that display the potential to host several multi-million ounce gold deposits within this relatively small 3 by 5 kilometre core area. With an existing multi-million ounce gold resource open for expansion and numerous other high-quality targets within the 431 square kilometre land package, RC Gold is quickly emerging as the foundation of a potential new mining district in the Yukon."

Contact-Pukelman Target
Six holes totalling 2,172 metres have been completed as part of the ongoing 5,000 metres of drilling planned at the Contact-Pukelman target. Drilling intersected broad intervals of strongly altered metasediments cut by several quartz monzonite, and biotite-feldspar porphyritic dykes, along with abundant, cm scale, sheeted quartz veins. Visible gold was observed in the sheeted quartz veins and was often associated with arsenopyrite, bismuthinite, and minor scheelite (see Figures 1 and 2).
Sitka's 2025 drill program is planned to expand the mineralized footprint of the Contact zone, test the zone with oriented diamond drill core to better understand controls on the mineralization and test the linkage between the metasedimentary and intrusion hosted mineralization of the Contact and Pukelman zones. The Contact zone was previously drilled in 2010 and 2011 with 1,660 metres in 12 holes of reverse circulation drilling and 254 metres in 2 holes of diamond drilling (see Table 1) and encountered significant mineralization in quartz veining within metasedimentary rocks up to 450 metres south of the Pukelman intrusion. Current drilling to date has traced gold mineralization across a lateral extent of approximately 900 metres x 650 metres and from surface to a depth of approximately 430 metres (see Figure 3 and Table 1). While this is an encouraging indicator of the potential size of this target, the Company cautions that additional drilling and assay results are required to confirm the extent and continuity of gold mineralization within this area.
* While visible gold observations are very encouraging and confirm the presence of gold mineralization, they are not intended to imply potential gold grades. Gold assays will be published after they are received from the lab for mineralized intervals in which visible gold particles were noted.

About the Flagship RC Gold Project
Sitka's 100% owned RC Gold Project consists of a 431 square kilometre contiguous district-scale land package located in the heart of Yukon's Tombstone Gold Belt. The project is located approximately 100 kilometres east of Dawson City, which has a 5,000 foot paved runway, and is accessed via a secondary gravel road from the Klondike Highway which is usable year-round and is an approximate 2 hour drive from Dawson City. It is the largest consolidated land package strategically positioned mid-way between the Eagle Gold Mine and the past producing Brewery Creek Gold Mine.
The RC Gold Project now has pit-constrained mineral resources that are contained in two zones: the Blackjack and Eiger gold deposits with 1,291,000 ounces of gold in 39,962,000 tonnes grading 1.01 g/t gold in an indicated category and 1,044,000 ounces of gold in 34,603,000 tonnes grading 0.94 g/t in an inferred category at Blackjack and 440,000 ounces of gold in 27,362,000 tonnes grading 0.50 g/t gold in an inferred category at Eiger. These resource estimate numbers are supported by the recently updated technical report for RC Gold, prepared in accordance with NI 43-101 standards, entitled "Clear Creek Property, RC Gold Project NI 43-101 Technical Report Dawson Mining District, Yukon Territory", prepared by Ronald G. Simpson, P. Geo., of GeoSim Services Inc. with an effective date of January 21, 2025. This report is available on SEDAR+ (http://www.sedarplus.ca) and on the Company's website (www.sitkagoldcorp.com).
Both of these deposits begin at surface, are potentially open pit minable and amenable to heap leaching, with initial bottle roll tests indicating that the gold is not refractory and has high gold recoveries of up to 94% with minimal NaCN consumption (see News Release July 13, 2022).
As of the end of 2024, the Company has drilled 72 diamond drill holes into this system for a total of approximately 25,136 metres. Other targets drilled to date include the Saddle, Josephine, Rhosgobel and Pukelman zones. The resource expansion drilling in 2023 at Blackjack produced results of up to 219.0 metres of 1.34 g/t gold including 124.8 metres of 2.01 g/t gold and 55.0 metres of 3.11 g/t gold in drill hole DDRCCC-23-047 (see news release dated September 26, 2023) and in 2024 results of up to 678.1 metres of 1.04 g/t gold starting from surface in DDRCCC-24-068, including 409.5 metres of 1.36 g/t gold, 93.0 metres of 2.57 g/t gold and 5.5 metres of 17.59 g/t gold (see news release dated October 21, 2024). Results from DDRCCC-25-075, completed during winter drilling in 2025, produced the best high-grade intercepts drilled to date at Blackjack, returning 352.8 metres of 1.55 g/t gold including 108.9 metres of 3.27 g/t gold and 45.0 metres of 4.52 g/t gold (see news release dated April 22, 2025).
A planned 30,000 metre diamond drilling program for 2025 is currently underway at RC Gold.

About Cobra
In 2023, Cobra discovered a rare earth deposit with the potential to re-define the cost of rare earth production. The highly scalable Boland ionic heavy rare earth discovery at Cobra's Wudinna Project in South Australia's Gawler Craton is Australia's only rare earth project amenable for in situ recovery (ISR) mining - a low cost, low disturbance method enabling bottom quartile recovery costs without any need for excavation or ground disturbance. Cobra is focused on de-risking the investment value of the discovery by proving ISR as the preferred mining method and testing the scale of the mineralisation footprint through drilling.
Cobra's Wudinna tenements also contain extensive orogenic gold mineralisation, including a 279,000-ounce gold JORC Mineral Resource Estimate, characterised by low levels of over-burden, amenable to open pit mining.

Appendix 1: Background information - the Boland HREE Project and ISR
Cobra's unique and highly scalable Boland discovery is a strategically advantageous ionic rare earth discovery where high grades of valuable heavy and magnet rare earths occur concentrated in a permeable horizon confined by impermeable clays. Bench-scale ISR testing has confirmed that mineralisation is amenable to ISR mining. ISR has been used successfully for decades within geologically similar systems to recover uranium within South Australia. Results of this metallurgical test work support that, with minor optimisation, ISR techniques should enable non-invasive and low-cost production of critical REEs from Cobra's Boland discovery.
- The Boland HREE Project was discovered by Cobra in 2023. Mineralisation is ionically bound to clays and organics within palaeochannel sands within the Narlaby Palaeochannel
- Mineralisation occurs within a permeable sand within an aquifer that is saltier than sea water and is confined by impermeable clays
- ISR is executed through engineered drillhole arrays that allow the injection of mildly acidic ammonium sulphate lixiviants, using the confining nature of the geology to direct and lower the acidity of the orebody. This low-cost process enables mines to operate profitably at lower grades and lower rates of recovery
- Once REEs are mobile in solution in groundwater, it is also possible, from an engineering standpoint, to recover the solution to surface via extraction drillholes, without any need for excavation or ground disturbance
- The capital costs of ISR mining are low as they involve no material movements and do not require traditional infrastructure to process ore - i.e. metals are recovered in solution
- Ionic mineralisation is highly desirable owing to its high weighting of valuable HREOs and the cost-effective method in which REEs can be desorbed
- Ionic REE mineralisation in China is mined in an in-situ manner that relies on gravity to permeate mineralisation. The style of ISR process is unconfined and cannot be controlled, increasing the risk for environmental degradation. This low-cost process has enabled China to dominate mine supply of HREOs, supplying over 90% globally
- Confined aquifer ISR is successfully executed globally within the uranium industry, accounting for more than 60% of the world's uranium production. This style of ISR has temporary ground disturbance, and the ground waters are regenerated over time
- Cobra is aiming to demonstrate the economic and environmental benefits of recovering ionic HREOs through the more environmentally aquifer controlled ISR - a world first for rare earths

Lahontan Acquires Strategic Claims South of The York Pit, Expanding The Santa Fe Mine Project
Lahontan Gold Corp. (TSXV:LG)(OTCQB:LGCXF)(FSE:Y2F) (the "Company" or "Lahontan") is pleased to announce that the Company signed a binding term sheet (the "Term Sheet") on August 18, 2025 to acquire 27 unpatented lode mineral claims (the "YorkClaims") from Emergent Metals Corp. ("Emergent"),adding approximately 2.1 km2 of strategic mineral rights to the Santa Fe Mine Project. The claims adjoin the Santa Fe Mine Project immediately south and southeast of the York open pit and gold mineral resource* (please see map below). Resource modeling completed as part of the recent Preliminary Economic Assessment ("PEA") of the Santa Fe Mine Project* demonstrated that gold-silver mineral resources extended in the direction of the York Claims. The acquisition of the York claims will allow the expansion of the York open pit and potentially, a substantial increase of mineral resources in the York area.
Kimberly Ann, Lahontan Gold Corp CEO, Executive Chair, and Founder commented: "Lahontan is very excited to acquire the York Claims that are directly adjacent to the York gold mineral resource*. The newly acquired claims will allow a considerable layback of the York pit during mine planning and in mineral resource estimation. Modeling of gold and silver mineralization at York in the Santa Fe Mine Project PEA was constrained by a pit shell that must honor the property boundary*. With the addition of the York Claims, that pit can be greatly expanded, potentially adding resource ounces plus opening up compelling targets for further gold and silver mineral resource expansion. Coupled with recently completed exploration drilling, the Company continues its path of growing size and scale of the Santa Fe Mine Project and enhancing shareholder value".
Emergent and Lahontan contemplate completing a Definitive Agreement (the "Agreement") within 30 days of signing the Term Sheet. The transaction (the "Transaction") is subject to all necessary approvals, including regulatory approval. Terms of the Transaction include:
- On signing the Term Sheet, Lahontan will pay Emergent's U.S. subsidiary, Golden Arrow Mining Corporation ("GAMC"), a sum of US$10,000.
- On signing the Agreement, Lahontan will issue GAMC a US$50,000 promissory note, with a 1% per month interest rate, and payable within six months of signing the Agreement.
