Kiniéro Gold Mine, Guinea
The Kiniero Gold Project is PDI Gold’s flagship operating asset, having successfully achieved first gold pour in late 2025 and transitioned into commercial production in early 2026. This milestone marks a critical step in establishing PDI Gold as a leading West African gold producer.
Located in Guinea’s highly prospective Siguiri Basin, Kiniero provides near-term production and cash flow, underpinning the development pathway for the Bankan Gold Project and supporting the long-term growth strategy of the combined group.
Kiniero comprises a 470km² package of mining licences, including the Kiniero Mining Licence and the adjacent Mansounia Exploration Licence, which together host multiple deposits and substantial exploration upside.
Geology
The Kiniero gold project lies within the Siguiri Basin in the Birimian Greenstone Belt of West Africa. The geology of the project area is characterised by volcanic and sedimentary lithologies comprising fine-grained sedimentary rocks and intrusive volcanic rocks in greenschist facies.
Gold mineralisation at Kiniero is hosted in shear zones and is typically associated with late-orogenic and structurally controlled medium-grade lodes occurring within quartz veins or in quartz-veined fracture zones with inter-mineralisation intrusives.
Mining
Initial mining is from the Sabali South open pit. Mining in upper oxide layers will be free-dig with drill-and-blast required in areas that mine through the transitional material into fresh rock. The free-dig nature of the oxide zones was confirmed by extensive previous mining at the site.
A grade control drilling program was completed ahead of production, which reported an 11.5% increase in tonnes, a 3.08% higher grade and 14.58% more contained ounces relative to the previous Mineral Resource calculation.
First gold was poured at Kiniéro in December 2025 with commercial production achieved in February 2026, following commencement of mining at Kiniéro in Q3 2025 and the first blast in October 2025.
Kiniéro has a current mine life of 9 years with average gold production of 139,000oz per annum, using conventional open pit mining methods.
Processing
A new 5 million tonne per annum (5Mtpa) carbon-in-leach (CIL) plant is in operation at Kiniéro following construction and commissioning.
The flowsheet includes two crushing circuits, semi-autogenous, ball grinding, and pebble crushing milling (SABC), dual CIL circuits, split Anglo-American Research Laboratories (“AARL”) elution, gold electrowinning, and carbon regeneration.
Ore is processed on site. The gold is recovered in a beneficiation plant designed to process a blend of oxide, laterite, transition, and fresh ores from various ore deposits.
Oxide and upper transition ores (soft) require less comminution energy than laterite and fresh ore (hard). However, they present other challenges in handling due to the sticky nature of oxide ore types, justifying dedicated crushing devices for soft and hard ores.
Exploration
Kiniero sits within a highly prospective structural corridor and offers substantial upside through both brownfields and greenfields exploration.
PDI has planned ~133,200 metres of drilling across about 1500 holes in FY26. The program will focus on near‑mine resource conversion, pit expansion opportunities and high‑impact new discoveries, with priority targets including Sabali, Mansounia, Mankan and the broader Northern prospects. This targeted exploration strategy is designed to extend mine life, improve strip ratios and strengthen long‑term production flexibility, positioning Kiniero for sustained growth.
