Gold earnings accounted for almost half of total goods exports, underscoring both the upside and the vulnerability in Tanzania’s current mining boom.

Gold as anchor of exports and reserves

Gold now sits at the core of Tanzania’s trade and reserve strategy. According to recent trade intelligence compiled by TICGL, gold exports rose 46.7 percent to US$5.53bn in the year ending May 2026. The metal accounted for 47.6 percent of goods exports, up from 38.2 percent four years earlier. Over that period, gold exports grew 105.6 percent, roughly 2.7 times faster than non-gold exports.

This surge reflects both price and volume effects. The Bank of Tanzania has reported strong growth in mineral export values, driven mainly by gold. Indicative prices from the Tanzania Mining Commission placed gold around US$4,100 per troy ounce in early July 2026, supported by safe-haven demand. As a result, gold has become Tanzania’s single largest foreign-exchange earner, with export receipts from the metal rising to about US$5.3bn in the year to April 2026, up from US$3.8bn a year earlier.

The central bank has moved to lock in part of this boom. Governor Emmanuel Tutuba disclosed that the Bank of Tanzania has purchased around 28 tonnes of gold over the past 18 months, worth roughly US$3.68bn at current prices. This programme follows a 2024 directive requiring miners and traders to sell at least 20 percent of exported gold to the central bank. The build-up has lifted official reserves to about US$6bn, covering just over four months of imports, and strengthened the shilling.

Industry reforms have reinforced these trends. Authorities have expanded formal mineral markets, which has brought more artisanal and small-scale production into the official system and helped reduce smuggling channels. At the same time, recent Finance Act changes have aligned tax treatment with investors’ framework agreements, addressing a source of project-finance uncertainty in the sector.

Concentration risk and the case for strategic minerals

However, the upside has a clear flip side. Central bank and industry data show that mining value is heavily concentrated in a single commodity and a few regions. In the quarter ending March 2026, the value of mineral recovery reached about US$1.61bn, with gold contributing US$1.44bn or 89.2 percent of the total. Coal accounted for 5.2 percent, graphite 0.7 percent and nickel 0.3 percent, while diamonds, gemstones and tanzanite each remained below 1 percent.

Geographical concentration is equally stark. The Lake Zone, driven by gold mining in Geita and Shinyanga, generated 67.6 percent of total mineral recovery in that quarter, valued at roughly US$1.09bn. The Southern Highlands contributed about US$217.8m, or 13.5 percent. This pattern amplifies the impact of any future gold price reversal or operational disruption in a handful of mines.

Industry leaders are therefore pushing for accelerated development of strategic minerals. The Tanzania Chamber of Mines highlights the country’s confirmed deposits of graphite, nickel, rare earth elements and uranium, many at advanced exploration or project-development stages. New gold projects such as Nyanzaga are expected to add to output, but the Chamber’s message is clear: long-term resilience will depend on bringing non-gold projects into commercial production.

Supply-chain specialists stress the missed opportunity from delayed projects stuck in licensing or early-development phases. Every mine that reaches production supports local suppliers, logistics and contractors, spreading benefits beyond export earnings. Policy reforms that streamline approvals, stabilise fiscal terms and deepen local capital markets will be key to unlocking these pipelines.

For investors, the current environment offers a two-track story. Near term, Tanzania gold exports provide strong cash-flow visibility, supported by sizeable reserves purchases and still-robust global safe-haven demand. Structurally, the policy and industry push towards graphite, nickel, rare earths and other strategic minerals positions Tanzania as an emerging platform for the energy-transition metals trade.

The next phase to watch is how fast delayed projects move to final investment decisions and how effectively the state manages the balance between gold-driven strength and broader mineral diversification.
