Expression of Interest For Provision Of Project Management Works For The Current Definitive Feasibility Study

Expression of Interest for Provision of Project Management Works for the Current Definitive Feasibility Study Scope of Work for Owners Team (Project Management): DFS Delivery Framework & Control Establish and enforce a structured DFS execution framework aligned to Obsideos staged methodology, including: Definition of stage gates, aligned with: Flowsheet maturity Testwork completion Design freeze points Implementation of: Change control system Design development tracking Assumption register Development of a fully integrated DFS execution plan, Logical progression from testwork design costing No premature advancement of engineering without sufficient data maturity Metallurgical Testwork Integration (Critical Workstream) Oversee the entire metallurgical testwork program, including: Sample selection strategy Test program sequencing Laboratory coordination Ensure: Testwork is representative of ore variability Results are statistically and technically robust Enforce direct linkage between testwork outputs and flowsheet evolution Prevent: Design assumptions not supported by test data Misinterpretation or over-extrapolation of results Validate recovery assumptions, reagent regimes, and process stability Process Design & Flowsheet Development Provide active technical challenge to Obsideos process development, including: Review of: Comminution circuit selection Gravity/flotation performance assumptions Water balance and recycling strategy Validation that: Design reflects real operating conditions (not ideal lab conditions) Equipment sizing aligns with variability and throughput requirements Ensure formal flowsheet freeze points are only approved when: Testwork confidence is adequate Mass balances are stable Key risks are understood and mitigated TSF Trade-Off Study Management Reflecting the parallel workstream defined in the tender, Sentinel will: Structure and control the TSF trade-off study as a formal decision process Ensure all options are assessed consistently across: Technical viability CAPEX and OPEX Environmental and social impacts Constructability and operational risk Prevent premature selection of TSF solutions Deliver a clear, evidence-based recommendation suitable for Board approval Cost Estimation & Financial Integrity Given Obsideos staged cost development approach, Sentinel will: Review cost estimates at each stage of maturity Ensure: Alignment between design maturity and estimate accuracy No false precision in early-stage costing Sentinel will validate: CAPEX (target ±15% DFS accuracy) OPEX assumptions (reagents, power, labour, maintenance) Additionally, Sentinel will: Benchmark costs against comparable tungsten operations Identify: Cost escalation risks Value engineering opportunities Schedule & Critical Path Management Develop and maintain an integrated Level 3 schedule, incorporating: Testwork timelines Design progression Review and approval cycles Managing testwork-driven critical path risks Avoiding downstream delays caused by late data or rework Reporting & Decision Support Provide structured reporting aligned to Trinity governance: Weekly Progress vs plan Testwork updates Design changes Immediate risks Monthly DFS health (cost, schedule, scope) Stage gate readiness Key technical decisions required Decision Papers Flowsheet selection TSF option selection Major capital decisions These will be board-ready and defensible DFS Integration & Finalisation Ensure the final DFS is: Fully integrated across all disciplines Internally consistent (no conflicting assumptions) Aligned with: CPR requirements Financing expectations Lead: Final DFS review workshops Gap analysis prior to issue Eligibility and Competency Requirements: Interested parties must have Competency: Proven track record in tungsten feasibility studies, TSF design, and gravity plant engineering. Accreditation: Membership in professional organizations (AusIMM, SAIMM, etc.) is required. Compliance: Must meet environmental, social, and safety standards in Rwanda. Capacity: Ability to manage owners team, coordinate consultants, and deliver a complete DFS package.
