Executive Summary

Giyani announced the Definitive Feasibility Study (DFS) results for its 100%-owned K.Hill battery-grade manganese project in Botswana.
Post-tax NPV (8%) of US$481.5M, post-tax IRR of 20.3% (real terms), with a 25-year mine life.
Proven & Probable mineral reserves of 5.35Mt at 12.0% Mn; initial capex of US$535M (US$480M base + US$55M contingency).
Steady-state production ~220ktpa run-of-mine feed, producing high-purity manganese sulphate monohydrate (HPMSM) and high-purity manganese oxide (HPMO); average HPMSM price assumed US$3,220/t, HPMO US$4,004/t.
Construction target: start April 2027, first ore feed March 2029.
The DFS incorporates operational data from the Johannesburg demonstration plant; a QP-reviewed technical report will follow within 45 days.

Material Impact

The DFS marks a critical technical milestone, converting a substantial portion of the Measured & Indicated resource into reserves and quantifying robust project economics for the first time.
The NPV and IRR are healthy but not exceptional; the project’s viability is now formally established, significantly de-risking the asset ahead of financing and offtake negotiations.
Development timeline (first ore 2029) aligns with the expected 2028+ surge in battery-grade manganese demand from next-generation EV and energy-storage chemistries.
The company’s market capitalization (inferred very small relative to the US$481M NPV) suggests the stock may be materially undervalued if the market prices in successful development; however, the US$535M upfront capex far exceeds the company’s current financial capacity, meaning financing risk remains the key overhang.
The DFS was previously guided for Q1 2026, then revised to Q2 2026 in March. Delivery in late May is slightly later than the initial Q1 target but largely in line with updated guidance; the content itself is incrementally positive but not a surprise.
Stock price reaction will likely be positive but capped by the realization that a massive funding gap still exists. The DFS is a prerequisite for securing EXIM debt and offtake, so it removes a major uncertainty.

Company Overview

Giyani Metals Corp. is a battery-grade manganese developer focused on its 100%-owned K.Hill project in Botswana, a mining-friendly jurisdiction.
The project aims to produce high-purity manganese sulphate monohydrate (HPMSM) and high-purity manganese oxide (HPMO) for the cathode/precursor market, supplying western EV and energy-storage supply chains.
A demonstration plant in Johannesburg successfully produced both HPMSM (Sept 2025) and HPMO (Q1 2025), validating the proprietary flowsheet and providing operational data for the DFS.
