What we do

Across base and precious metals, our work spans the upstream sourcing, logistics, risk management, and structuring of financing solutions that move material from mine to market. Backed by Hartree Partners and Oaktree Capital, our team brings decades of experience across major trading merchants, miners, smelters, and banks.

We leverage deep market insights and a global network to create value-driven solutions for our partners, ensuring efficiency and stability in an ever evolving commodities landscape. Our commitment to our customers is to build long-standing relationships based on value creation, integrity, and delivery.

Physical trading

We source, ship, and deliver metals, matching supply with demand through end-to-end logistics, blending, warehouse, and transport solutions.

Financing

We structure prepayments, investment, and trade finance solutions that unlock value across the supply chain — backed by the financial strength of Hartree and Oaktree Capital.

Risk solutions

To manage volatile markets, we work with counterparties to design pricing structures, manage exposure across the LME and other venues, and absorb the operational risk.

Group Solutions

Through the Group's wider platform, we connect clients to our refined and battery metals desks, renewables, carbon offsets, venture capital, and consulting divisions — supporting your broader needs.

Traded metals

We trade base and precious metal concentrates, semi-refined, and intermediate products, which underpin a range of industries, products and critical infrastructure.

Cu

Copper

Powering grid infrastructure, EVs, and renewables, while underpinning the AI build-out through data centre wiring and cooling systems.

Zn

Zinc

Zinc plays an important role in transportation, energy storage, healthcare, infrastructure, renewable energy, consumer products, and food security.

Pb

Lead

Used in energy storage, backup power for data centres and telecoms, and grid stabilisation, alongside radiation shielding, defence applications, and industrial systems.

Ni

Nickel

Essential to stainless steel, aerospace superalloys, and defence-grade materials, while playing a central role in the lithium-ion batteries powering EVs and energy storage.

Au

Gold

Serving manufacturers as a critical input for high-reliability electronics, semiconductors, and aerospace and defence systems, and the global jewellery trade — alongside investors for its underlying value.

Ag

Silver

Used in high-conductivity electronics across AI hardware and semiconductors, medical and defence applications, and solar panel production, while remaining an important investment asset.

Sb

Antimony

A critical mineral used in flame retardants, lead-acid batteries, and semiconductors — with growing strategic importance in defence applications and next-generation energy storage.

+

Intermediate & semi-refined products

Concentrates, anodes, blister, and other intermediate forms — bridging the gap between mine output and refined metal.

Case studies

Our transactions take into account our client needs, and adapted to volumes, timing, metal quality, financing, and wider trade terms. The examples below show how those have taken shape across different geographies, commodities, and counterparties.

South America → Asia · Copper concentrate

Sourcing zinc, lead and silver concentrate from South America to Asia

Working with a portfolio of small - medium- and large-scale producers across countries such as Peru, Chile and Bolivia we source zinc, lead, and silver concentrates, coordinate inland trucking and warehousing, and manage port loading. Shipments are delivered into a South Korean and Chinese smelters under a multi-vessel programme.

Australia · Zinc & Lead concentrate · Prepayment

US$25 million offtake financing for Broken Hill Mines

Hartree partnered with Broken Hill Mines (ASX: BHM) on a four-year senior secured offtake financing facility of US$25 million (approx. A$40 million) to support growth at the Rasp and Pinnacles silver–lead–zinc operations. The structure combined flexible drawdown over the first 12 months with a long-term offtake of 200,000 tonnes of lead concentrate on market-competitive terms, alongside a spot agreement covering interim Rasp production.

Namibia · Copper concentrate · Prepayment + offtake

Financing first production at the Hope and Gorob copper project

Hartree partnered with Bezant Resources (AIM: BZT), an early-stage developer, to bring its Hope and Gorob copper project in Namibia to commercial close and through to first production. The structure combined a US$7 million secured prepayment facility to fund construction and commissioning with a life-of-mine offtake covering 100% of copper concentrate. Production is targeted for the third quarter of 2026, with concentrate shipped through the port of Walvis Bay.
