Bramaderos Gold-Copper Project, Southern Ecuador New gold-copper porphyry discovery points to more growth at Bramaderos
The Copete discovery takes the Bramaderos mineralised cluster to 2km x 1.8km, highlighting scope for large open pit operation
Key Points
- Trench sampling results from the new Copete gold-copper porphyry target at Bramaderos have confirmed significant surface porphyry gold-copper mineralisation:
- o 113m at 0.64g/t gold-equivalent2(0.51g/t gold, 0.07% copper, and 1.2g/t silver) in trench ML-01, within
- o 214.0m at 0.50g/t gold equivalent2 (0.37g/t gold, 0.08% copper, and 1.1g/t silver)
- It is interpreted that copper is leached at surface and that higher grades of copper are expected in drilling
- The Copete discovery is next to the Brama-Alba Resource and the large Melonal target
- The Bramaderos cluster of gold-copper mineralised bodies at surface now covers 2km x 1.8km, highlighting the potential for a large open pit operation
- Bramaderos, along with the El Palmar project in northern Ecuador, is currently the subject of partnership discussions with third parties
- These discussions are aimed at accelerating exploration and Resource growth to help unlock the full value of the projects
Sunstone Metals Ltd (ASX: STM) is pleased to announce that it has discovered another significant gold-copper porphyry at its Bramaderos Project in southern Ecuador.
The Copete discovery is in addition to the previously released porphyry Exploration Target of 3.3 – 8.6Moz AuEq1,2 at Bramaderos and therefore presents significant scope for that Bramaderos Exploration Target to be increased. The potential tonnage, grade and quantity of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource for the target area reported. It is uncertain if further exploration will result in the estimation of a Mineral Resource.
The Copete discovery means Sunstone has now outlined a 1.8km-long cluster of porphyry gold-copper mineralised intrusions across the Melonal – Copete trend. This trend runs parallel to the Brama-Alba trend and is located only a few hundred meters to the south (see Figures 1 and 2).
The Copete target remains largely under-explored, with no drilling by Sunstone – but now with a coherent and wide mineralised trench intersection, a 3-D modelled magnetic anomaly plunging to the SE comparable to that
seen at Brama and mapped stockwork veining interpreted to represent the upper levels of an intact porphyry system (see Figure 2).
It is interpreted that copper is leached at surface, and that higher grades of copper are expected in drilling. This is supported by individual 2m intervals returning up to 0.28% copper (ML-01c 31-33m grading 0.45g/t gold, 2.4g/t silver and 0.28% copper).
Sunstone Managing Director Patrick Duffy said*, "The Copete porphyry is another exciting new discovery that adds to the large-scale potential at Bramaderos, and we don't expect it to be the last.*
"Copete is located next to the 2.7Moz AuEq2 Brama-Alba Resource and the large Melonal exploration target, which further highlights the potential scale of the opportunity at Bramaderos.
"Taken together, it reinforces that Bramaderos is a world-class multi-decade mining opportunity and increases the Project's value to third parties looking for hard-to-find gold and copper projects with genuine scale".

About Sunstone Metals
Sunstone Metals Limited ("Sunstone" or "Company") is an ASX-listed mineral exploration company with two world-class gold and copper projects in Ecuador:
- The Bramaderos Project, located in Southern Ecuador, has both at-surface and deeper porphyry goldcopper systems and contains an initial Mineral Resource estimate of 156Mt at 0.53g/t AuEq for 2.7Moz AuEq1,2 .

| Total | 156 | 0.35 | 0.11 | 1.3 | 0.53 | 2.7 |
Additionally, the Bramaderos Project has a porphyry Exploration Target7 of between 3.3Moz and 8.6Moz AuEq within 255Mt to 360Mt at a grade between 0.40 and 0.74g/t AuEq1,2 , and the Limon epithermal gold-silver Exploration Target7 of 0.9 - 1.7Moz AuEq4 within 30Mt - 44Mt at a grade between 0.9 - 1.2g/t AuEq3,4 .
- The El Palmar Project is located in northern Ecuador, 60km north-west of Ecuador's capital Quito. The property sits on the regionally significant Toachi Fault Zone that hosts a number of world-class copper porphyry systems. The Project has both at-surface and deeper porphyry gold-copper systems and an initial Mineral Resource estimate of 64Mt at 0.60g/t AuEq5,6 for 1.2Moz AuEq6 .

2 The gold equivalent calculation formula for porphyry gold-copper-silver mineralisation at Bramaderos is AuEq(g/t) = (Au grade x Au price x Au recov / 31.1035) + (Ag grade x Ag price x Ag recov / 31.1035) + (Cu grade x Cu price x Cu recov / 100)) / (Au price x Au recov / 31.1035). The prices used were US$1,800/oz gold and US$9,500/t copper and US$22/oz silver. Recoveries are estimated at 89% for gold, 85% for copper, and 60% for silver based on metallurgical studies.
3 Refer ASX Announcement on 5 February 2024.
4 The gold equivalent calculation formula for the Limon epithermal gold-silver mineralisation is AuEq(g/t) = Au(ppm) + (Ag (ppm)/82). The prices used were US$1,800/oz gold and US$22/oz silver. Recoveries are estimated at over 90% for gold and 90% for silver from metallurgical studies.
5 Refer ASX Announcement on 22 October 2024.
6 The gold equivalent calculation formula for porphyry gold-copper-silver mineralisation at El Palmar is AuEq (g/t) = ((Au grade x Au price x Au recov / 31.1035) + (Ag grade x Ag price x Ag recov / 31.1035) + (Cu grade x Cu price x Cu recov / 100)) / (Au price x Au recov / 31.1035). The prices applied were US$1,800/oz gold, US$4.50/lb copper and US$22/oz silver. Recoveries are estimated at 90% for gold, 78% for copper (excluded for oxide material), and 60% for silver based on metallurgical studies.
7 The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Resource for the exploration target area reported. It is uncertain if further exploration will result in the estimation of a Resource.
Strategy
The porphyry projects at Bramaderos and El Palmar have the potential to evolve into multi-decade goldcopper mining centres. At Bramaderos, the Limon epithermal deposit has been prioritised as a potential nearsurface high-grade gold-silver development opportunity. This strategy allows for a scalable operation to be established first before developing the much larger porphyry gold-copper-silver opportunities at Bramaderos.
The Company continues to evaluate potential new opportunities to continue to grow our business in Ecuador, where clear shareholder value can be demonstrated. It is also evaluating potential partnerships for its projects where this may maximise the value of the portfolio.
Track Record
The team at Sunstone has been involved in significant discoveries of porphyry and epithermal copper-gold mineralisation at Tujuh Bukit in Indonesia and Cascabel in Ecuador, and the successful development of the King of the Hills Gold Mine in Western Australia and Koniambo Nickel Mine and Smelter in New Caledonia. The Company continues to attract specialist resources executives and is well-placed to repeat that success at Bramaderos and El Palmar.
Excellent infrastructure
All projects are supported by established infrastructure close to power, road and rail infrastructure and ports.
Community support
The Board and Management Team take their responsibilities to the host communities seriously and have endeavoured to implement the highest ESG standards throughout our business. Sunstone released its inaugural Sustainability Report in 2023, which details the level of support and engagement with local communities and project stakeholders.
