Cobalt is a mineral critical to paint, battery, and military industries. Most of the global cobalt supply is mined in the Democratic Republic of the Congo (DRC), under highly exploitative conditions. The extraction of the DRC’s mineral wealth began under Belgian colonial rule, laying the groundwork for enduring patterns of foreign control over Congolese resources. In 1960, the DRC gained independence and Patrice Lumumba, the country’s first prime minister, declared that foreign powers could no longer plunder their wealth with impunity.

Lumumba’s stance alarmed Western governments, who feared he might align with the Soviet Union. In a plan orchestrated by the United States Central Intelligence Agency (CIA), Lumumba was assass****** and a pro-Western regime was installed.

Jonah Hoffman examines how histories of extraction, colonialism, and geopolitics are bound to the materiality of painting. He creates self-reflexive paintings that expose their own material conditions, depicting studio tools, pigment mining landscapes, and screens displaying reference imagery. His work moves between abstraction and hyperrealism, combining print, paint, and text to produce a hybridity of language and technique that foregrounds the processes and systems that construct the painting. His current focus is cobalt, a mineral used in pigments, batteries, and military technologies, and often extracted under exploitative conditions in postcolonial regions. Hoffman works with cobalt blue as both material and subject, tracing the global systems of energy, labour, and power that produce the colour.
Hoffman completed his MFA at Goldsmiths, University of London in 2025, and his BFA at School of the Art Institute of Chicago in 2020.

In lead up to the exhibition for our annual open call we will be doing a series of studio visits with artists on the long list.
Jonah Hoffman (b. United States, 1998) is a painter based in London whose work examines how histories of extraction, colonialism, and geopolitics are bound to the materiality of painting.
He creates self-reflexive paintings that expose their own material conditions, depicting studio tools, pigment mining landscapes, and screens displaying reference imagery. His work moves between abstraction and hyperrealism, combining print, paint, and text to produce a hybridity of language and technique that foregrounds the processes and systems that construct the painting.
His current focus is cobalt, a mineral used in pigments, batteries, and military technologies, and often extracted under exploitative conditions in postcolonial regions. Hoffman works with cobalt blue as both material and subject, tracing the global systems of energy, labour, and power that produce the colour. Through painting, he reveals how art production and everyday technology are embedded in systems of exploitation, treating this violence as an imminent presence within painting’s materiality.

Our annual open call focused on artists connected to South London, supporting a community facing rising rents and shrinking studio space. Since launching in 2023, we’ve exhibited 46 artists across three editions, selected from hundreds of applications each year.
The first edition featured 8 artists, followed by 14 in 2024, and 24 in 2025, reflecting the breadth and energy of practices rooted in South London today. This year, we received over 700 applications and will be announcing a shortlist of artists who will be exhibited as part of South Open 4.
Today, cobalt is in our pockets. Cobalt is in the rechargeable battery in your phone, laptop, headphones, smartwatch, and electric vehicle. The same cobalt that once painted America’s cultural dominance now underpins the technological infrastructure of contemporary life. America’s predatory foreign policy and the exploitation of the DRC continues.
