Tantalex Lithium Announces Start of Commissioning on its TiTan Tin and Tantalum Plant

The TiTan plant which has been designed with a capacity of 130 tonnes per hour is now entirely assembled and ready to process its first ore. The commissioning period will last up to 3 weeks and the first ore is expected for export in September.

Eric Allard, CEO of Tantalex Lithium commented "Our team in the DRC have worked relentlessly in challenging conditions over the last few months to build the TiTan plant and I could not be more proud of what they have accomplished. This is transformational for our company as we progress towards a revenue generating mining company and demonstrate our commitment to the DRC in bringing critical mineral discoveries and resources to industrial production stage."

SUPPLY CHAIN ASSESSMENT, DUE DILIGENCE AND MONITORING

Tantalex is also pleased to announce it has secured the services of RCS Global Group / Better Mining to implement its Upstream Assurance Mechanism (UAM) Services for its mining operations on the TiTan plant. This mechanism combines two permanent processes: Due Diligence and Monitoring (Better Mining) and Digital Supply Chain Traceability (RCS TRACE).

Through this service agreement, Tantalex is implementing a traceability system to enable the export of tin and tantalum from the DRC in compliance with the provisions of the Dodd Frank Act Section 1502, the Responsible Minerals Initiative's (RMI) responsible sourcing requirements and OECD Due Diligence Guidance (OECD DD Guidance - v3) for Responsible Supply Chains of Minerals from Conflict Affected and High-Risk Areas (CAHRAs). It allows supply chain actors to know whether sourcing activities are free from conflicts, human and labour rights abuses, and unacceptable health and safety hazards.

COMMUNITY DEVELOPMENT PLAN

Tantalex has established an ongoing relationship with the "Carter Center" since February 2023 and secured their formal assistance to guide the implementation of an exemplary Community Development Plan for the TiTan project, the first of its kind in both Tanganyika and Haut-Lomami provinces.

Since 2007, the Carter Center's Human Rights House has been partnering with Congolese local civil society organization and human rights activists to create lasting changes by promoting collaborative action and establishing networks of like-minded organizations; providing technical and organizational trainings; and connecting them with needed resources. Through these partners, the Center currently supports efforts aimed at protecting human rights defenders, advancing women's rights, and promoting positive engagement of youth in public life.

In 2018, the Carter Center inspired modifications to the DRC Mining Code of new provisions concerning community development plans to be established in collaboration with the communities affected by mining projects.

In May 2022, to help mining companies operating in the DRC implement these new regulations, the Carter Center produced a Practical handbook to negotiations, instructions and execution of the specifications of social responsibility for mining companies in the DRC, with the financial support of German Cooperation (GIZ).
