PGMs — Platinum Group Metals Summary

Platinum Group Metals (PGMs)

The platinum group forms a family of six noble metallic elements, characterized by their exceptional catalytic properties, extreme corrosion resistance, and high melting points. They are the molecular pillars of modern chemical and technological industries.

Platinum (Pt): Fundamental to clean energy, acting as the primary catalyst in hydrogen fuel cells and advanced catalytic converters. Used in high‑precision sensors and thermocouples.
Palladium (Pd): Critical for miniaturized electronics, being essential in the manufacturing of Multi Layer Ceramic Capacitors (MLCCs) present in almost all electronic devices. It is also vital in hydrogen purification and storage.
Rhodium (Rh): One of the rarest metals in the world. Its extremely high selective reactivity makes it irreplaceable in the reduction of nitrogen oxides (NOx) in exhaust systems, besides being used in fiber optics and highly reflective mirrors for space instruments.

Iridium (Ir): The most corrosion-resistant metal known. Essential in the manufacturing of crystallization crucibles for growing single crystals used in semiconductors. It is also the key piece in PEM electrolysis technology for "green hydrogen" production.
Ruthenium (Ru): Used as a hardening agent for Platinum and Palladium. At the technological forefront, Ruthenium is critical for thick-film resistors and emerging magnetic random-access memory (MRAM) technologies in supercomputers.
Osmium (Os): The densest naturally occurring element on the planet. Its extreme hardness is exploited in specialized alloys for highly durable electrical contacts and precision instrument pivots.

REE — Rare Earth Elements Summary

Rare Earth Elements (REE)

Composed of 17 chemical elements (15 lanthanides, plus yttrium and scandium), Rare Earths are the “vitamins of modern industry.” Their unique magnetic, electrochemical, and luminescent properties are the invisible foundation of miniaturization and energy efficiency.

Neodymium (Nd) & Praseodymium (Pr): The engines of electrification. Together, they form the basis of ultra-high-power permanent magnets (NdFeB), irreplaceable in electric vehicle (EV) motors, wind turbine generators, and military guidance systems.
Dysprosium (Dy) & Terbium (Tb): Heavy rare earth elements added to Neodymium magnets to ensure they do not lose their magnetization (coercivity) when operating under the extreme heat of industrial and automotive motors.
Yttrium (Y): Essential for phosphors in LED lighting, superconductors, and high‑temperature ceramics.
Europium (Eu) & Gadolinium (Gd): Critical for medical imaging, neutron capture, and high‑precision optical and magnetic applications.

Scandium (Sc) — Origin: Brazil When scandium is combined with aluminum (Al‑Sc), it produces next‑generation lightweight structural materials with strength comparable to titanium, but at a fraction of the weight, while maintaining full mechanical integrity even after welding. It is a strategic material for the defense industry, spacecraft, and additive manufacturing (3D printing). In the energy sector, it is essential for enhancing the efficiency of Solid Oxide Fuel Cells (SOFCs).
Lanthanum (La) & Cerium (Ce): Vital for advanced battery alloys, petroleum refining catalysts, and precision polishing of optical lenses (glass and silicon wafers).

High‑Purity Graphite (C) — Origin: Brazil

High‑Purity Graphite (C)

Carbon in its most structured crystalline form. Brazil stands out as one of the largest players and holders of high‑crystallinity natural graphite reserves in the world.

Technological Importance:

Graphite is not just an industrial lubricant or refractory material; it is the indispensable anode material for lithium‑ion batteries.
Due to its excellent electrical and thermal conductivity, and ion intercalation capacity, high‑purity graphite processed from Brazilian sources is the central axis sustaining the global electric mobility revolution.
It is also the direct precursor for graphene research and development.

Lithium (Li) — Strategic Battery Metal

Lithium (Li) and Lithium Carbonate (Li2CO3) – Origin: Argentina

Lithium is the lightest metal and the essential charge carrier in modern energy storage systems. Its unique electrochemical properties make it the irreplaceable basis for lithium-ion batteries. Lithium is the "white oil" of the energy transition.

Jubesa LLC maintains technical operations and a strategic presence in the heart of the Lithium Triangle, specifically in the provinces of Catamarca and Salta, in Argentina, where our team conducts regular field visits, due diligence and homologation of salt flats and producers.

Strategic Importance:

Lithium enables high energy density, fast charging, and long cycle life in EV and stationary storage systems.
Its role in cathode and electrolyte formulations makes it the backbone of global electrification.
Demand for battery-grade lithium compounds continues to grow as nations accelerate the transition to renewable energy.

Niobium (Nb) — High‑Strength Alloying Metal

Niobium (Nb) – Origin: Brazil

With Brazil holding over 90% of the world's operable reserves, Niobium is one of the most coveted strategic metals on the planet. Niobium is a critical alloying element used to enhance the strength, toughness, and corrosion resistance of advanced steels and superalloys.

Scandium (Sc)

Scandium enhances aluminum alloys, producing lightweight, high‑strength materials for aerospace, defense, and advanced manufacturing.

Aluminum‑Scandium Alloys: High strength‑to‑weight ratio for aerospace.

Advanced Manufacturing: Critical for next‑generation structural materials.

Niobium — Strategic Applications:

The addition of minute fractions of Niobium to steel creates HSLA alloys.
Essential for aerospace fuselages, pipelines, smart infrastructure, automotive.
NbTi alloys are the basis for superconducting magnets in MRI and accelerators.
Global demand rises due to advanced infrastructure and energy technologies.

Other Strategic Minerals (Origin: Brazil and the Southern Cone)

Other Strategic Minerals

The South American subsoil provides the infrastructural basis that allows emerging technologies to scale. Jubesa LLC audits and fosters supply chains for:

Copper (Cu): The nervous system of electrification. Without high-grade copper, there are no smart grids, efficient motors, or connected electronics.
Silica / Quartz (SiO₂): The foundation of the Information Age. Fundamental for processing metallic silicon, used in semiconductors, microchips, fiber optics, and photovoltaic solar panels.
Iron Ore (Fe): We operate with ultra-high-grade Brazilian reserves, essential for reducing the carbon footprint (CO₂ emissions) in the global steelmaking process.
Kaolin: An aluminum silicate mineral essential for coating advanced ceramics, catalysts, and as a high-strength inert material in automotive plastics and rubbers.
Manganese (Mn): In addition to desulfurizing and deoxidizing steel, it is gaining vital prominence in new cobalt-free electric vehicle battery chemistries, such as NCM (Nickel-Cobalt-Manganese) and LMFP (Lithium-Manganese-Iron-Phosphate) batteries.

Friction Elimination: This model eliminates "middlemen" in the commodities market, ensuring capital and technological development flow directly from the end-user to the extraction operation.

II. Hemispheric Synergy: Intelligence at the Source and Destination

Our operational intelligence is divided into two perfectly synchronized fronts, ensuring end-to-end control:

South American Team (The Source): Field professionals, geologists, and compliance specialists working directly in mines and laboratories across Brazil, Chile, and Argentina.
North American Team (The Market and R&D): Our US-based executive and scientific structure translates South American geological wealth into the technical requirements of American industry.

Hemispheric Synergy — Intelligence at Source and Destination

III. Supply Chain Resilience and Technological Sovereignty

Our mission is to guarantee the stability of the American technological future by supplying the United States with ethical, vast, and secure mineral sources located in the Western Hemisphere.

Eliminating Dependence: By developing projects in South America and connecting them directly to the US market, we help eliminate critical dependence on high geopolitical risk countries.

IV. Absolute Transparency and Asset Security

The security of the supply chain is a matter of national and corporate security. We operate under the strictest compliance and auditing protocols.
