These Regulations, comprising 11 sections, amend the principal 2018 Regulations to refine definitions, strengthen operational oversight, and enhance joint venture requirements within Tanzania’s mining sector. In particular, the changes concern: (i) the introduction of a definition of a Tanzanian financial institution and the expansion of oversight through the inclusion of the Director of the Mineral Audit and Trading Department within the Mining Commission’s structure; (ii) joint venture and procurement requirements mandating non-indigenous suppliers to partner with 100% Tanzanian-owned companies (with at least 20% local equity), the establishment of a list of goods and services reserved for local firms, and the requirement for Mining Commission approval of joint venture agreements; (iii) operational procedures and sub-plans, including automatic approval of revised local content plans if no response is received within 50 working days, the requirement for banking and procurement sub-plans, and the setting of a sole-sourcing threshold above the TZS equivalent of USD 10,000; (iv) the Expression of Interest (EOI) framework, requiring contractors to submit prequalification information to the Commission prior to issuing EOIs, with a minimum submission period of seven days.
