## ARTICLE:

Zambia's mining sector is experiencing renewed investor confidence as AIM-listed junior explorer Tertiary Minerals accelerates its exploration programme across multiple licences in the Southern African copper belt. The acceleration signals broader momentum in Zambia's resource sector, where policy reforms and commodity price recovery are rekindling appetite for copper and cobalt development.

### Why Zambia's Exploration Scene Is Heating Up

Zambia remains Africa's second-largest copper producer and a critical supply node for global EV battery demand. However, operational costs and regulatory uncertainty had deterred mid-tier explorers for years. Tertiary Minerals' renewed activity reflects a shift in investor sentiment, driven by three factors: (1) copper prices hovering near $10,000/tonne—supporting marginal project economics; (2) the Zambian government's 2024 mining reforms, which reduced royalty rates and clarified environmental licensing; and (3) a global supply deficit expected through 2026 as major producers struggle with ore-grade decline.

For Tertiary Minerals, an AIM-listed entity with a market cap of roughly £15–20 million, scaling exploration means drilling campaigns, geological surveys, and resource estimation work across concessions in the Copperbelt and Northwestern provinces. This de-risks assets ahead of potential partnership or development discussions—a common path for junior explorers in Zambia.

### What Market Impact Should Investors Watch?

The broader significance lies in Zambia's ability to attract exploration capital without sovereign risk premiums. Under previous administrations, junior miners faced unpredictable fiscal treatment and delayed permitting. The current government's commitment to predictable rules has already unlocked exploration spending from companies like Konkola Copper Mines and Mopani—both now ramping activity.

For portfolio investors, three implications emerge: **First**, successful exploration by juniors de-risks larger development capex, potentially attracting majors (Rio Tinto, Glencore, Anglo American) into Zambia again. **Second**, if Tertiary or peers define new copper resources, Zambia's production trajectory extends beyond 2040, improving sovereign credit narratives. **Third**, exploration success reduces foreign exchange pressure on Kwacha, supporting long-term macroeconomic stability.

### How Does This Affect Commodity Markets?

Tertiary's acceleration is a micro signal within a macro trend. Zambia's copper output fell from 800,000 tonnes (2015) to ~700,000 tonnes today due to underinvestment. New exploration-to-development pipelines could add 100,000–200,000 tonnes of annual capacity by 2030, helping offset supply losses in Peru and Indonesia. In a market where refined copper demand from EV makers and grid infrastructure is expected to grow 5–7% annually, even marginal production gains move prices.

The AIM listing also matters: UK-listed juniors face institutional ESG scrutiny, so Tertiary's work will likely emphasise low-carbon mining practices and community engagement. This standards-lifting benefits Zambia's sector reputation globally.

### When Could Results Emerge?

Exploration timelines vary. Tertiary's current phase (likely 12–18 months) will yield geological reports and maiden resource estimates. If results are positive, the firm may seek strategic investment or farm-in partnerships within 24–36 months. Major announcements would likely move both Tertiary's share price and sentiment toward Zambia's mining index.
