This result was from Channel 11 and helps to build on previous sampling from Channels One and Six, where assays included 23.4m at 0.88% Cu and 16.8m at 0.52% Cu, respectively.

The data suggests Cinto features porphyry copper mineralisation of several styles across a potential area measuring 30 kilometres long and 0.75 kilometres wide, and Solis plans to follow this up with an induced-polarisation (IP) survey – for which planning is already underway – to aid in defining drill targets.

Drilling at Cinto will begin in the second half of 2025. (Solis has initiated permitting.)

“These results confirm the significant potential at the Cinto Project, where we’ve substantially expanded Solis’ porphyry copper mineralisation footprint,” Solis CEO Mitch Thomas said on the news.

And, he declared, expectations have now been raised. “Notably, we’re seeing mineralisation styles similar to those at the major Toquepala mine, just 15km away.”

The region’s governments are becoming increasingly aware of the need to shore up future supplies of a wide range of commodities and are working to attract more activity.

The region has been perhaps best recognised for lithium and the ‘Lithium Triangle’ spanning Argentina, Bolivia and Chile. However, with lower lithium pricing, the focus has shifted to include materials including gold, silver, copper, mineral sands, phosphate, uranium, and more.

Because many jurisdictions have been under-explored in Latin America, ASX-listed companies are finding projects of a quality that’s now very difficult to secure in Australia.

What’s also pleasing those companies working in the region is that operational costs, such as power and labour, are dramatically cheaper. They are finding that approval processes are moving faster.

In this webinar, you’ll hear about the risks and the potential rewards – with facts and figures for investors to consider.

We ask company leaders what attracted them to Latin American projects, we discuss the potential impacts of Donald Trump’s tariffs, and we look at their experiences in developing a variety of projects.

This yields 9.1 million ounces of AuEq – an increase from 4.5Moz of AuEq.

Specifically, the update comprises an MRE of 4.4Moz gold equivalent at a grade of 0.50 g/t AuEq for the Colorado V project – which Challenger has a 50% stake in, and a 4.7Moz AuEq at 0.50 g/t AuEq for El Guayabo.

Colorado V’s AuEq is estimated to include 0.35 g/t Au, 2.2 g/t Ag, 0.08% Cu, and 14.3 ppm Mo, while El Guyabo’s comprises 0.38 g/t Au, 2.3 g/t Ag, 0.06% Cu, and 7.5 ppm Mo.

“I would like to congratulate our exploration team in Ecuador for their outstanding work in doubling project resources from 4.5Moz to 9.1Moz AuEq, including a high-grade core of 2.1Moz at 1.0g/t AuEq,” managing director Kris Knauer said.

Challenger achieved the MRE upgrade through drilling of five of the 15 regionally significant Au-Cu soil anomalies identified across the territory; of these 13 have been drilled, with all returning significant mineralisation.

“This resource update represents a transformational milestone for Challenger Gold shareholders, enabling us to move forward with unlocking significant value from our Ecuador assets while focusing entirely on bringing our flagship Hualilan project into production,” he added.

The Venatica copper project sits on the northern extension of this belt and is comprised of 34 claims across 337 square kilometres of territory.

It is also located only 60 kilometres from MMG Ltd’s Las Bambas mine, which is responsible for 2% of the global copper supply. And, crucially, Venatica contains the same host rocks, structures, and geological controls as Las Bambas, including grades of more than 6% copper found in outcroppings.

Within Venatica’s regional system, Altair has identified two main targets: Irka NE – a high-grade felsic porphyry measuring four square kilometres with copper, silver and moly mineralisation – and Irka SW, a copper-gold porphyry-skarn measuring more than six square kilometres.

The most promising is Irka NE, which is defined as an “exceptionally large target,” featuring significant copper presence across a strike of 3.4km, with collected samples showing between 3,000 and 60,000 parts per million copper.

However, the majority of the project is untested, and Altair believes it can uncover more high-grade copper systems there. Additionally, the true lateral extent of both porphyry systems remains completely open.

Altair shares have jumped on the news, and at 11:52 AEDT, they were trading at 0.3 cents – a rise of 40% since market open.

Today’s agreement will see Cosmos acquire 100% of EAU Lithium Pty Ltd, a company also engaged in a technology partnership agreement with Vulcan Energy Resources (ASX:VUL) in addition to a recently signed agreement with Bolivia’s state-owned lithium company, Yacimientos de Litio Bolivianos (YLB).

Per the latter, EAU would be able to test lithium brines from Salar de Coipasa, Salar de Empexa and Salar de Pastos Grandes, with the potential for expansion to other salars across Bolivia as a precursor to a long-term JV partnership with YLB.

The Bolivian government wants to use the country’s notable lithium resources and become a supply chain leader in the mineral, using YLB as a vehicle.

However, high magnesium content in the Salars has proven challenging for extraction using solar evaporation with chemicals; YLB believes it can overcome this by partnering with EAU to leverage Vulcan’s direct lithium extraction (DLE) technology.

The brines in question are being transported to Germany for testing with VULSORB A-DLE technology, and if successful, the tech agreement could lead to the signing of industrialisation agreements to facilitate a joint venture partnership between YLB and EAU.

Cosmos executive chairman Jeremy Robinson said the acquisition represented an important step for the company.

“This agreement is an exciting step for Cosmos Exploration as we align ourselves with EAU Lithium and their existing partnerships with YLB in Bolivia and Vulcan Energy Resources,” he said.

“EAU’s recently signed technology agreement gives them the opportunity to testlithium brines from Bolivia’s premier salt lakes using Vulcan Energy’s state-of-the-art VULSORB technology.

“While the results of this testing will determine the next steps, the potential for this to progress into an industrialisation agreement in a joint venture for the processing of brines is a significant milestone in the sustainable development of Bolivia’s world-leading lithium resources.”

Cosmos shares rose on the news, and at 10:44 AEDT, they were trading at 4.7 cents – an increase of 34.29% since the market opened.

The company has been progressing a 4,000 metre drilling program at the La Verde porphyry copper-gold target, and results from the first two holes have shown an intersection of 202 metres at 0.6% copper and 0.3 grams per tonne (g/t) from 70 metres depth.

This was found within a broader intersection measuring 308 metres, with a copper grade of 0.5%, in addition to gold grading 0.3g/t from 46 metres depth to end of hole.

La Verde’s overall parameters are impressive, with a porphyry footprint measuring approximately 850 metres by 700 metres, making it comparable to Hot Chili’s higher-grade Cortadera Cuerpo 3 copper-gold porphyry, which is found 30 kilometres to the north.

Historically, an open pit mine on the site was previously exploited by private interests for shallow porphyry copper-style oxide mineralisation, although drill testing at depth and outside the central lease was limited.

Hot Chili has completed 12 reverse circulation (RC) holes – for a total of 3,150 metres – at La Verde, with the first two drilled to validate historic intercepts, and test the interpreted northern extension of the porphyry from the previously exploited open pit.

The company is progressing a prefeasibility study (PFS) at Costa Fuego – located in Chile’s Atacama region – set for completion in the first quarter of 2025.

Hot Chili shares rose on the news, and at 10:30 AEDT, they were trading at 72 cents – an increase of 5.88% since the market opened.

The discovery was made through trench sampling at the Copete gold-copper porphyry target, which confirmed significant mineralisation of this type at surface.

This included 113 metres at 0.64 grams per tonne (g/t) gold-equivalent (0.51g/t gold, 0.07% copper, and 1.2g/t silver) in trench ML-01, within 214.0 metres at 0.50g/t gold equivalent (0.37g/t gold, 0.08% copper, and 1.1g/t silver).

Sunstone has predicted that the red metal is leached at surface, and that drilling is likely to pick up higher grades.

The discovery holds particular significance for the Bramaderos porphyry exploration target – estimated as being between 3.3 and 8.6 million ounces – suggesting scope for it to be increased.

Managing director Patrick Duffy said he expected more positive news from the project in the future.

“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,” he said.

“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.”

Sunstone shares have been higher following the news, and at 12:10 AEDT, they were trading at 0.8 cents – a rise of 14.29% since the market opened.

La Verde – which is located 30 kilometres south of Costa Fuego, in Chile’s Atacama region – is made up of historical open pit workings, and has a history of private interests exploiting its shallow porphyry copper oxide mineralisation, with the latter occurring across a strike extent of around 800 metres, with widths of up to 200 metres and depths of up to 15 metres.

The mine area has also experienced very little drilling activity, with historic drilling only occurring on surrounding leases.

Hot Chili has entered into a three-year Option Agreement to take on the copper mine, which is also in the middle of the company’s recently consolidated landholding in the Domeyko district. The acquisition will mark the first time that the La Verde system has been held by a single party.

As part of its investment in the district, the company has undertaken exploration activities – including soil geochemistry, mapping and magnetics surveys – since April, and recently extended this over the La Verde copper mine area as part of the Company’s due diligence process, prior to the Option Agreement execution.

Additionally, the company kicked off a first pass drilling program in late October, with this comprising 11 RC drill holes for approximately 4,000 metres. Two holes for 800 metres have been completed, and have confirmed wide intersections of porphyry-style copper mineralisation in both holes, based on visual logging, with assay results pending.

Hot Chili is trading at 83.5 cents – a rise of 0.6% since the market opened.

At 11:36 AEST, Tesoro shares were sitting at 4 cents, a rise of 14.29 percent since the market opened.

The high-grade discovery was made during a diamond drilling campaign at the Drone Hill target, located approximately 700 metres northwest of the company’s 1.3-million-ounce Ternera gold deposit, with four targets overall being identified within a 1.5 kilometre radius of this site.

At Drone Hill, shallow and high-grade gold was intersected, with results from one hole including 1.8 metres at 77.15 grams per tonne from 59.2 metres including 0.8 metres at 173.00 grams per tonne from 59.2 metres.

Tesoro is awaiting results from four diamond drill holes at two other targets – two at Buzzard, and another two at Ternera East – with these to be reported in the following weeks.

Managing director Zeff Reeves said the results were impressive both in terms of strength and what they suggested about underlying mineralisation.

“The exceptional results returned from first pass drilling at Drone Hill are highly encouraging and represent some of the highest grades intersected at the El Zorro Gold Project to date,” he said.

“Gold discovered in these initial holes is associated with a northwest-trending fault systemthat also hosts high-grade mineralisation within the Ternera Gold Deposit.

“This fault system has the potential to link Ternera to Drone Hill over 700 metres of strike: we are focused on exploration at four high-priority targets to delineate additional shallow gold extending from or near to Ternera.

“Any additional resource ounces that are discovered so close to our existing deposit have the potential to meaningfully elevate the already attractive Ternera economics.”
