Caledonia Mining – 2025 ESG Report Design

Caledonia Mining Corporation is a Zimbabwe-focused gold producer, anchored by the Blanket Mine and building a growth pipeline through the Bilboes, Motapa and Maligreen projects. Its sixth ESG report had to set out a full year of environmental, social and governance performance, across governance, safety, people, communities, diversity and the environment, for an audience of investors, regulators, lenders and host communities. Digby Wells Environmental undertook the environmental consulting and developed the content; Caledonia commissioned TEA for the report design and publication. As with every report of this scale, we began with structure rather than layout: we mapped all 59 pages, chapter by chapter, with our Publication Planner tool, sequencing the highlights, KPIs, the CEO’s letter and each ESG chapter into a logical order before a single page was designed. Getting that architecture right is what keeps a disclosure-heavy report readable rather than overwhelming.

A 59-page ESG report only works if a reader can find their way and the design feels like the company. We built a brand-aligned visual system, drawing colour, typography and iconography from Caledonia’s identity and applying it consistently across every page and data point. A chapter-numbered tab system and an interactive, clickable contents let readers move between Governance, Putting People First, Our Communities and Society, Diversity, Equity and Inclusion and Safeguarding the Environment, while SDG icon grids connect the work to the global goals it supports. This is the publication design discipline that turns a compliance document into something stakeholders actually read.

An ESG report lives or dies on its data. We created report-aligned diagrams, data tables and infographics to present Caledonia’s 2025 performance clearly, including a five-year (2021–2025) KPI table so stakeholders can see the direction of travel, not just a single year. Highlight panels and infographics surface the headline numbers, US$31.9 million in local supplier spend (up from US$16.5 million), US$1.6 million in community investment, a 12.2 MW solar plant supplying around a fifth of the Blanket Mine’s power, and high levels of process-water recycling, each shown with prior-year comparatives. Presenting figures this way is the core of the data-led impact report design that lets investors and regulators judge progress at a glance.

The report is prepared in accordance with the GRI Standards, including the GRI 14: Mining Sector 2024 Standard, and aligned with the SASB Metals & Mining standard, IFRS S1 and S2, and TCFD-type climate disclosure, mapped throughout to the UN Sustainable Development Goals. Designing to that level of disclosure means handling dense tables, framework indices and footnotes without losing clarity, the discipline TEA brings to every ESG and sustainability report.

We delivered the report print-ready and as a navigable digital PDF with interactive, clickable contents, ready for investor, regulatory and community audiences. It sits alongside our work for the same advisor on the Andrada FY2025 Sustainability Report.
