INDUSTRIAL MINERALS / WEEKLY OUTLOOK
The development
The International Energy Agency’s Global Critical Minerals Outlook 2026, published 16 July, warned that export restrictions, supply concentration and reduced investment are increasing mineral supply risk. It reported a 9% fall in critical-mineral investment in 2025 and a rise in the average refining share held by the leading country from 70% in 2023 to 72% in 2025. The assessment also noted recovering prices across several metal and battery-material markets in 2025–early 2026. [1][2]

Why Nigeria should pay attention
Manufacturers increasingly want continuity, transparent provenance and predictable specifications. That creates a general opening for credible Nigerian mining and processing companies, particularly where customers seek diversification. However, IEA critical-mineral findings should not be read as evidence of an immediate international price boom for talc or quartz: these are distinct markets with different end uses, pricing mechanisms and qualification requirements.
For Terrae Vivae’s established quartz and talc business, the commercially relevant signal is procurement resilience. Refractory producers need dependable silica raw material for suitable ramming-mass formulations; ceramic manufacturers assess mineralogy, chemistry, whiteness, firing performance, particle size and contamination. Repeatable batches can be more valuable to an industrial customer than a temporarily low price.
How suppliers can capture the opportunity
Develop product-specific technical dossiers: representative chemical assay, mineralogical test when needed, sizing curve, moisture, packaging and source traceability.
Differentiate quartz suitable for refractory or ceramic use by grade, not appearance alone; confirm customer requirements for silica, iron, alkalis and particle distribution.
Qualify talc by actual end use. Ceramic-grade feedstock and filler-grade talc may have materially different performance and safety requirements.
Offer trial lots and jointly agreed acceptance criteria before negotiating longer offtake terms or committing to expensive processing upgrades.
Three risks operators should manage
First is specification failure: attractive ore can still fail a buyer’s test. Use independent laboratory results and retained reference samples. Second is overcapitalisation: a processing line without committed volume, power reliability and an understood recovery yield may destroy margin. Use staged pilot trials and sensitivity analysis. Third is licensing and operational exposure: verify tenure, permits, royalties, environmental obligations, haulage documentation and local community agreements before expanding production.
What to do over the next seven days
Build a buyer-application matrix for quartz and talc, showing application, required assays, target size, monthly volume and rejection thresholds. Take representative samples from each production source. Request two laboratory quotations and three current transport quotations. Recontact established refractory and ceramic customers with a trial-batch proposal based on measured specifications—not unverified purity claims.
Terrae Vivae perspective
The real competitive advantage for an established Nigerian mineral supplier is bridging mine and factory. In a world focused on supply security, reliability becomes a measurable product: correct grade, documented chain of custody and deliveries that manufacturers can plan around.
