#GSCU Great Southern Copper Research note:
Major #Copper-#Silver Discovery – Why GSCU is Hugely Undervalued
📢 Great Southern Copper (#GSCU) has just announced outstanding drill results from the Cerro Negro project in Chile, confirming a high-grade copper-silver discovery that could transform the company's valuation.
✅ Headline results:
•20m @ 3.3% Cu & 270g/t Ag from just 27m depth
•7m @ 5.72% Cu & 490g/t Ag within that zone
•3m @ 6.62% Cu & 563g/t Ag – extremely high-grade
•🔥 Peak grades of 6.79% Cu & 583g/t Ag
These grades are far higher than typical copper mines, and they confirm Cerro Negro has significant high-value mineralization.
🔍 Why These Results Are So Important
🔸 Exceptional Copper & Silver Grades
•Many major copper mines operate with grades between 0.5% and 1% Cu – Cerro Negro’s results are 3-6x higher.
•Silver mines often target 150-200 g/t Ag – these results are nearly 3x that
•Higher grades = more metal per tonne of rock = higher profitability.
🔸 Shallow Mineralization = Cheaper Mining
•The mineralization starts at just 27m depth, which is very shallow for a deposit this rich.
•This means it could be developed as an open-pit mine, which is significantly cheaper and easier than underground mining.
•Open-pit operations also allow for faster resource expansion and production.
🔸 600% Higher than Historic Grades = Major Revaluation Potential
•Previous exploration in the 1980s suggested Cerro Negro contained copper, but results were lower (~0.53% Cu).
•New drilling has shown grades over 6x higher than these historic results.
•This suggests previous studies massively underreported the deposit’s value, and the project could be much bigger than expected.
🔸 Still Open in All Directions = Even More Upside Potential
•The drill results confirm the deposit extends at depth and along strike.
•This means future drilling could significantly increase the size of the resource, making it an even bigger discovery.
•Follow-up drilling and metallurgical testing are already being planned, with results likely to drive further excitement.
📈 What This Means for GSCU’s Valuation
💰 GSCU is currently only a £10M market cap company.
•Companies with high-grade copper and silver discoveries often see valuations reach £50M-£100M+, even before resource estimates are finalised.
•If further drilling continues to confirm high-grade mineralization, the market could significantly re-rate GSCU higher.
⚡ Copper & Silver Demand is Booming
•Copper is critical for electrification, EVs, and renewable energy – demand is projected to surge.
•Silver is used in solar panels, electronics, and as a monetary metal – making it a key investment for the future.
•Cerro Negro is perfectly positioned to benefit from both trends.
🚀 The Investment Opportunity
✅ Exceptional high-grade results ✅ Open-pit mining potential ✅ Massively undervalued compared to peers ✅ Exploration upside still ahead ✅ Copper & silver demand booming
GSCU imo could be one of the most undervalued copper-silver plays on the market today.
⭐️Big grades. Low market cap. Huge re-rating potential.⭐️

#GSCU The #silver price smashing through US$90/oz couldn’t come at a better time for GSCU 🚀
Cerro Negro keeps delivering serious Ag firepower - 318 g/t, 442 g/t, 646 g/t, even peaks of 778 g/t Ag in Phase I–III drilling.
GSCU is perfectly positioned for the next leg of growth
(1/2) ⛏️ #GSCU has been conducting intensive drilling at the #Especularita Project, particularly within the Cerro Negro prospect. Phase III drilling at Cerro Negro is [completed], with 4,000m drilled, and there are further drill-ready targets in Especularita
(2/2) Drilling is fundamental to our strategy and has the potential to add real value. Sustained drilling which leads to discovery and resource drilling adds exponential value, attracting the potential for alternative funding sources that do not impact capital structure
(3/3) Assays are pending, and planning for the next drilling phase is underway, including additional targets identified at Mostaza, the Viuda prospect, and the Colorada lithocap porphyry #copper-#gold system
(2/3) Phase III drilling comprised 17 diamond holes for 2,923m, and 6 RC holes for 1,032m, extending the high-grade #copper-#silver system at Mostaza. Highlights include stacked Cu-Ag lenses, a new Ag-Pb-Zn lens, and oxide and sulphide mineralisation along trend
