Too many catalysts on the horizon, but each to their own it’s what creates the market I guess! Now we’re seeing emerging confirmation of a largescale Maricunga style porphyry system at Viuda Negra, at a time when gold is at all-time highs and copper is rallying.

RC005 12m @ 1.5 g/t Au & 0.47% Cu from 132m, including 2m @ 4.4 g/t Au & 0.94% Cu. Outcrop at Viuda Negra up to 4.2 g/t Au, 145 g/t Ag, 0.56% Cu

Early geochemical data shows grades and alteration intensifying to the south, so a potentially large and improving mineralised system

Confirmation of grade continuity at depth and across the outcropping zones. If mineralisation links between RC005 and the outcrop, it could signal a substantial system.

Validates GSC’s porphyry model

Major re-rating potential if grades and widths match or exceed RC results

Potential for farm-in interest or JV discussions, especially with majors looking for scale

Mostaza Phase II Results & Metallurgical Testing. Clarity on recoverability and scale of near-surface Cu-Ag mineralisation.

Fast-track toward near-term resource definition

Could support early-stage production studies

Valuable standalone or as part of a hub-and-spoke model (with Viuda, Cerro Negro)

Further Scout Drilling and Geophysics at Viuda (Southwards Extension) – Q2/Q3

Identification of deeper/higher-grade zones along the geochemical vector trends.

Expands scale and dimensions of the porphyry system

Supports definition of a maiden resource in 2025

Enhances project economics, especially with gold & copper prices high

Resource Definition Planning (across multiple targets) – H2 2025. Targets include Viuda Negra (Au-Cu-Ag), Mostaza (Cu-Ag), Cerro Negro (Cu-Au)

Brings GSC into valuation territory where explorers are typically valued per resource ounce/lb

Likely to attract institutional backing, funding deals, or acquisition interest

Strong base for dual pathway. large-scale development vs. exploration-led farm-outs

This is a textbook case of early porphyry discoverystage upside. The near-term catalysts are real and coming quickly.

If the diamond drill intersects at Viuda Negra deliver, we could transition from a microcap explorer into a serious name in the Chilean copper-gold space.

All to play for!!

We’ve gone from permit approvals to delivering some of the best copper grades in the junior exploration space in under five months. Along the way, we’ve confirmed multimetal porphyry potential, secured new capital, and kicked off an aggressive dual-rig drill campaign, all while holding 100% ownership options on our key assets.

December

Cerro Negro Permits Secured: We received the green light to commence drilling at Cerro Negro, a major milestone for one of our flagship assets. With permitting in place, rigs were mobilised swiftly.

JANUARY

Diamond drilling begins. This marks the first physical work on what we believe is a highly prospective, under explored system within the coastal metallogenic belt of Chile.

First Drillhole at Cerro Negro Completed. Early signs were promising. Alteration and veining characteristics were consistent with high-grade copper-silver systems.

FEBRUARY

Copper Mineralisation Extended at Mostaza! Drilling in the Mostaza pit confirmed that copper mineralisation extends deeper and further along strike than previous models suggested.

Cerro Negro Drilling Campaign Completed: The first pass at Cerro Negro wrapped up. Core logging and assays underway. A strong foundation set for analysis.

Game-Changing Assays at Cerro Negro with 20m @ 3.3% Cu & 270 g/t Ag. These results far exceeded expectations and confirmed that we’ve tapped into a high grade polymetallic system with serious silver upside.

MARCH

We successfully raised over £1.5m to fund continued exploration across Cerro Negro, Mostaza, and now Viuda. This was critical to ramping up activity and drilling with two rigs.

With cash in hand and market support, we launched Phase II diamond drilling at Mostaza. Two rigs were deployed testing depth extensions and lateral continuity of the high-grade lens hit in Phase I.

Best result: 4.4m @ 6.8% Cu, including 1.2m @ 12.4% Cu

Confirmed that high grade copper is not an anomaly. The system is consistent and improving at depth.

APRIL

More “Exceptional” Results at Mostaza Headline result 16.15% Cu in drill core. Sam says in interview this week “The highest result I’ve ever received in a drill hole in 35 years.” These assays confirmed a 600% grade increase compared to historic data at the same site. Depth extension confirmed to 100m vertical, and the mineralised lens remains open both at depth and along strike.

Viuda RC Drilling Results 12m @ 1.5 g/t Au + 0.47% Cu, including 2m @ 4.4 g/t Au + 0.94% Cu. Seven holes over 1,020m confirmed a broad-scale porphyry alteration system. Trace element trends, veining, and brecciation were textbook porphyry indicators. surface outcrops showed 4.2 g/t Au, 145 g/t Ag, 0.56% Cu

We’ve transitioned from grassroots explorer to serious high grade copper player in under six months….

Happy Easter holidays folks 🍫

A massive hint dropped in his video this week when he told us resiles from Viuda were “imminent” and the RNS drops at 7:00 the next day.

God bless that man 🫡

Can sell above 4p now

Break this and I think we’re heading to 5p fairly soon

We’ve got everything any investor could ever wish for here and now with gold thrown in the mix, I can see these rigs getting mobilised straight away down the road

Have a blessed Thursday and enjoy the extended weekend everyone, we’re in the most capable hands in the most copper rich country in the world with mineralisation surrounding our 100% licences

Drill hole RC005 yielded 12 meters at 1.5 g/t gold, including 2 meters at 4.4 g/t gold. Surface samples from Viuda Negra returned up to 4.2 g/t gold.

Refugio District (Maricunga Belt) The Verde and Pancho deposits have average gold grades ranging from 0.5 to 1.0 g/t. 

Cerro Maricunga Project Measured and indicated resources average around 0.51 g/t gold. 

These comparisons highlight that our grades, particularly the 4.4 g/t intercept and 4.2 g/t surface sample, are significantly higher than the average grades of established deposits in our region.

Such highgrade findings are uncommon in porphyry systems, which are typically characterised by large tonnage and lower grades.

The presence of these highergrade zones suggests the potential for economically viable mineralisation , especially in the current market with gold prices at ATH

Viuda and Viuda Negra have gold grades that are exceptional for porphyry style deposits in the Maricunga Belt, indicating a promising opportunity for further exploration, and more drills to come on site here as well.

Sheeted and stockworked quartz veins are a classic Maricunga porphyry signature and as Diamond drilling has just kicked off, I bet it’s only going to get bigger and better.

The outstanding thing is that the system is completely open. Alteration, trace elements, vectoring, all pointing south, and getting richer!

The presence of bornite is particularly noteworthy, as it often correlates with gold enrichment in porphyry systems, the mineralisation exhibits a west dipping tabular geometry, with continuity confirmed along a 270meter strike length to the south of the Mostaza mine.

This structural configuration, coupled with the intensity of alteration and sulphide assemblages, suggests proximity to the core of a porphyry system 🚀

With Mostaza showing bonanza copper and silver at surface. Bornite, chalcocite, chalcopyrite with every hole hitting mineralisation and with copper being the lifeblood of electrification and gold running at ATHs AND us being in Chile, one of the most mining friendly nations on the planet AND with infrastructure on tap, there’s no reason we can’t 50 bag from 4p to over £1BN market cap the way things are going in the next 3 years.

Sam knows what he’s doing and I’ll be following the next few weeks even closer than what we’ve discovered so see. This hasn’t even started yet and no one’s even ramping it anywhere! Bring on phase 2 results and more!!

Discovery of a new gold-silver prospect at Viuda Negra with outcrop samples grading up to 4.2 g/t gold and 145 g/t silver.

"With gold prices currently at all-time highs, the gold-silver rich Maricunga-style porphyry gold and copper vein alteration evident in outcrop at Viuda represents a very exciting target for GSC.

Wow 🚀🚀🚀🚀🚀

Just look at some of the absolute crap valued higher than this with all that’s going on right now.

There’s absolutely no reason it can’t be £60M +

Viuda is located in the Atacama Desert in Chile one of the world’s premier copper producing regions. This is world class mining territory, with major players like Codelco and BHP operating in the region.

The geology here is well-known for high-grade copper deposits, and wr are exploring in one of the most prospective areas for copper in the world.

High-grade copper in this region is incredibly valuable. A discovery here could significantly boost our valuation and position it as one of the top explorers in the space.

The potential lies in the fact that these highgrade zones could offer early cash flow opportunities if they can prove the size and continuity of the mineralisation.

This is what the market needs and wants to see scalable, economic discoveries that can support long-term mining projects.

The Viuda project is still in its exploration phase, but with Cerro Negro already delivering incredible results 16.15% copper ffs! and Viuda on the brink of releasing its own results, the excitementis building up fast.

Investors are starting to get the sense that we could be sitting on a massive copper discovery. It’s rare to see grades like this, and if Viuda’s results confirm what we expect, GSC could be looking at a world-class project.

While not immediately adjacent, both projects are in the same geological region(50 odd miles) The proximity in terms of geology and infrastructure makes this area extremely promising!

Next RNS is extremely important and imminent.. hope we see something before bank holiday to get excited about over the long break

Sam Garrett, CEO of @greatscopper, said: "The 16.15% copper result is the highest assay result received to date for the project. These are the highest results l have ever received in a drill hole in my 35 years as a geologist.

"Phase II diamond drilling is well under-way with two rigs now in the Mostaza pit testing the depth extensions of the high-grade mineralisation identified in Phase I. To date all Phase II holes have intersected the mineralised lens to a vertical depth of 100m below the original hole 1 intercept.

"Excitement is building at Cerro Negro, but we have a lot of work ahead of us as we seek to demonstrate the size and economic value of this exciting high-grade deposit."

What a feeling that must be, career highlight and only just getting started on this project.. ££££££££

Of course the number of shares in issue matters. Even the smallest of increases in buying volume can cause disproportionately large price moves if no one’s selling!

Supply & Demand?

Another reason to like this business is that many junior exploration companies have billions of shares in issue, often with large free floats, particularly after years of fundraising through equity placings!!

GCSU

Implied shares outstanding 550.85M

Free Float 218.57M

% held by insiders 61.43%

% held by institutions 4.87%

quite conservative compared to many peers who’ve been diluted into the billions.

Comparison with Exploration Peers (AIM & small-cap LSE):

1. Bushveld Minerals (BMN)

• Shares in issue: ~1.3 billion

• Free float: ~900 million

• Frequent placings and share issuances

2. Kodal Minerals (KOD)

• Shares in issue: ~20 billion (yes, really)

• Free float: Very high, estimated >90%

• Extremely diluted over time

3. Greatland Gold (GGP)

• Shares in issue: ~5 billion

• Free float: ~3–4 billion

• Was once a market darling; highly liquid

4. Xtract Resources (XTR)

• Shares in issue: ~1.4 billion

• Free float: High (likely over 70–80%)

warrants little and often exercised to fund the campaigns is what excites me here as well!!

Just to add to the excitement of dreaming, ALL THIS IS ESTIMATED of course 😮‍💨

Blue-Sky Estimate (Full 25km Strike)

If mineralisation of similar grade/width is confirmed along the entire 25,000m strike:

Volume = 25,000m × 15m × 100m = 37,500,000 m³

Tonnage = 37.5M m³ × 2.9 t/m³ = 108.75 million tonnes

That would put Cerro Negro into Tier 1 territory, especially with grades consistently over 2–5% Cu.

Based on just the early drilling footprint (~500m), we may already be sitting on over 2 million tonnes of high-grade copper-silver ore. If they can extend this style of mineralisation over even a fraction of the 25km strike, the tonnage potential could leap past 100 million tonnes.

Assumptions for Estimation

Tonnage:

Approximately 2.2 million tonnes based on earlier volumetric calculations.

Average Grades

Copper (Cu): ~3.5%

Silver (Ag): ~250 g/t

Metal Prices

Copper Approximately $10,500 per tonne 

Silver Approximately $33.49 per ounce 

Estimated In-Situ Metal Content and Value

Copper

Contained Copper: 2.2 million tonnes × 3.5% = 77,000 tonnes

Value 77,000 tonnes × $10,500/tonne = $808.5 million

Silver

Contained Silver 2.2 million tonnes × 250 g/t = 550,000,000 grams

Convert to Ounces 550,000,000 g ÷ 31.1035 = 17,680,000 ounces

Value

17,680,000 oz × $33.49/oz = $592 million 

Total estimate value

Copper $808.5 million

Silver$592 million

Combined Value $1.4 billion

In-Situ Value. Represents the total value of metals in the ground, not accounting for extraction costs, recovery rates, or other operational expenses.

Actual recoverable metal will be less due to processing losses. Metal prices are subject to change, affecting the overall valuation. Mining, processing, and environmental compliance costs can significantly impact profitability.

Nothing on LSE like it IMO ticks all boxes. Location, BOD, experience, news flow, opportunity, off the radar..

Hard to come across companies that tick all boxes!!

Who can be at fault for dreaming here?

Sam just dropped eye-catching results with the headline number being a copper assay hitting 16.15% Cu and 646 g/t silver 😳 To break it down…

Anything above 1% Cu is generally considered decent.

2–3% Cu is strong

5%+ Cu is high-grade

10%+ Cu is elite tier

16.15% Cu - Make your own mind up

For comparison…

Freeport’s Grasberg (Indonesia) averages around 1% Cu.

Kamoa-Kakula (DRC), one of the highest-grade new copper mines globally, reports grades between 5% and 6% Cu

BHP’s Escondida (Chile), the world’s largest copper mine, averages well below 1% Cu now due to depletion.

So, 16.15% Cu is mins bowing exceptional.

But … it’s only a single sample and early days, but if that kind of high-grade mineralisation is continuous and scalable which Sam has been hinting at with multiple holes hitting good intercepts, this could be a seriously valuable asset.

Also worth noting:

They’re seeing 33m of 1.96% Cu so it’s not just ultra-high but also reasonably thick

And the mineralisation is open in all directions and at depth, there’s plenty of upside and never drilled areas before, which makes this absolutely worth dreaming about

16.15% is rare air even by global standards.

Wake up every morning excited to see what’s next and can’t wait to see the Phase II results continue to come in!

That’s what we like to see

Check out the amount of projects on the latest video

This is going to £1BN mcap by 2030 if they fully realise what they’re discovering

Maybe more

Clearly reading the forums discussing the Lonon Circle Line scale etc.

this project is bigger than any of us anticipated, me thinks

🚀 No stopping you

5p coming in today I can feel it

A seasoned geologist with over 30 years of experience in mineral exploration, particularly in copper and gold. Throughout his career, he has been instrumental in several significant mineral discoveries across the globe.

Notable Discoveries

Mt. Elliott Cu-Au Mine (Queensland, Australia): Garrett contributed to the discovery of this copper-gold deposit, which has been a significant source of these metals in the region.

Dinkidi Cu-Au Mine (Philippines): He played a role in identifying this copper-gold deposit, adding to his portfolio of successful exploration projects.

Tujuh Bukit Au-Ag-Cu Deposit (Indonesia): Garrett was involved in the discovery of this high-sulphidation porphyry deposit, which has since become a prominent mining site. 

Havieron Au-Cu Project (Western Australia): He was one of the early geologists to recognize the potential of the Havieron deposit, which has developed into a significant gold-copper project. 

As the CEO of Great Southern Copper PLC (LSE: GSCU), Garrett is leading exploration efforts in Chile. Notably, the company has identified a new porphyry copper-gold target at the Viuda prospect within the Especularita Project. Recent sampling revealed high-grade mineralization, with rock chip samples showing up to 3.5% copper, 13.85 g/t gold, and 56.6 g/t silver. These findings suggest the potential for a significant porphyry copper-gold system in the area.

^ various sources

I think the “catch” is that others don’t have an eye for it like Sam and the world class geologists he has on board. It was probably seen as a small little project back in the day when the mine was recorded to be extracting 600% less grades which was probably due to lack of technology and quality of labs and geologists then so no one ever thought to go back and look

Speculating here of course but logically makes sense to me

Don’t see it often

Shareholders and BOD know exactly they’re doing financial wise.

Been there. Done that. GGP
