Abstract : This study examined the effectiveness of risk management processes employed in the Lumwana Mine Fiber Optic Project, focusing on the identification, assessment, and mitigation of risks. A case study exploratory design was utilized, drawing on a mixed-methods approach to provide both quantitative and qualitative insights. Primary data was collected through structured questionnaires and interviews with project managers, technical staff, and stakeholders involved in the implementation of the fiber optic project. Quantitative data was analyzed using STATA software, applying descriptive statistics such as frequencies, percentages, and means to summarize trends and patterns. Chi-square analysis was used to assess associations between risk management variables and project performance indicators. Qualitative data was analyzed thematically to contextualize and deepen understanding of study findings. Findings indicate that risk management is centralized, with the Project Management department and Project Manager primarily responsible for risk identification, documentation, and communication, using risk registers (40%), brainstorming (24%), and expert consultations (20%), while spreadsheets (50%) dominate tracking. Risk management is most emphasized during implementation, with technical risks (32%) prioritized. Key risks affecting project execution include technical failures (36%), supply delays (32%), budget overruns (40%), environmental hazards such as dust pollution (24%), and human- related issues like skill shortages (36%). Statistically significant associations were found between technical risks and supplier delays, and between financial constraints and perceived subcontractor performance risks (p < 0.001). Mitigation strategies rely on expert consultation, stakeholder workshops, preventive maintenance, budget reserves, contingency planning, and early detection, though gaps exist in capturing lessons learned and consistently applying procedures. Challenges include limited expertise (32%), inadequate training (40%), time constraints (28%), financial limitations (36%), poor communication, and organizational bureaucracy. The study highlights the need for structured documentation, formal communication channels, capacity building, and proactive risk mitigation to enhance project performance and continuity. The study recommends strengthening supplier engagement through improved evaluation and monitoring, enhancing financial planning with tighter budget controls and clear subcontractor agreements, and simplifying risk management procedures for better accessibility.
