• Assisted management in the development of long-term strategic plans for company growth and expansion focusing mainly on improved efficiencies to lower mining costs and increase mine reserves
• Providing guidance to process plant engineering team in scoping implementation of solar energy that projects to result in a $7million cost saving over the life of mine and reduce logistical requirements for fuel transport
• Co-ordinating with HR on staff rotation between Wahignion and Boungou Mines to foster skills transfer, shared services and diverse operations exposure of staff

• Overseeing migration of planning from Use of Datamine suite to Surpac and Minesched in line with all Endeavour Mining operations
• Re-sequenced in the Life of mine schedule to eliminate ore gaps that existed on a previous schedule and
• ·This allowed more Pits to have waste mined designated to back-fill dumps and thus reduced hauling costs with the outcome that $1500 Pit shell became economic as opposed to previous $1300 Pit Shells and therefore increasing reserves by 120Koz
• Modified Blasting parameters to eliminate problematic boulders that used to be generated and reduced Utilisation of Rock breakers to one below 30% from above 83% previously while excavator productivity rose above previous benchmark of 550 BCM/hr. to above 650 BCM/hr.
• Reduced the 11% Ounce gap that existed between Budget 2022 and Q1 Forecast to 1% at the end of the year through Pit staging and scheduling with reduced haulage cost attained by backfilling opportunities created.
• Building a Culture of Safety consciousness leading to no LTI’s for 2022 and 2023
• Acting as General Manager and Mining Manager in the absence of the two incumbents

Establishment of the firm and business development

Projects: Mine to mill optimisation and medium-term planning support of Barrick Lumwana mine where our input resulted Improved blast fragmentation and downstream benefits of;

· Excavator productivity increased from 2900tonnes per hour to 3200 tons per hour

• Reduction in crusher bridging time by 38%
• Increased daily crusher throughput by 16% to 83.5kt per day
• Operations Review of Lupoto and KIMIN mines for 2022 operational readiness
• Served as an external Chief Mine Planning Engineer for Allied Gold at Sadiola Mine from November 2021 to March 2022

Developing capacity to create life of mine schedules with site personnel and skills development for engineers recruited to develop a pipeline of planning engineers for the project with a view of achieving Tasiast 2020 Mauritanization of Jobs Program. Achievements include.

• Drafting and implementing standard practice for use of Surpac and MineSched to develop intermediate and long-term plans which became a go to guide for these tasks
• Pit design review to encompass dewatering infrastructure and pit staging
• Conducted Ongoing skills development of 4 Junior Planning Engineers
• Re-design of Western waste Dump and its Ramping system network to reduce linear haulage distance by 1.2km resulting in a saving of $2.44 Million over 5 months of H1 of 2020.
• Leading initiative to ensure Pit ramps are on design grade to ensure smooth running of dump trucks up-ramp and minimise “horse backs” where rock spillage tended to occur on ramps.
• Running LOM schedules in support of Strategic business updates and paths to value for Tasiast Expansion Projects.

Took on some work on a part time basis

For Managem;

· Was assigned to Managem's Sudan project, Block 15 in Wadi Gabgaba where I helped standardize mining operation and created a spatially referenced schedule using MineSched to replace previous schedules formulated in excel and made it available to their technical hub (Reminex) staff for review and onward implementation.

· Revised pit designs into stages to allow optimisation of mining fleet to meet mill feed targets and strip waste for a continued smooth ounce profile.

For Micon International;

· Ultimate Pit Optimisation, design and Life of mine Plan on behalf of Azer Gold in support of a Sulphides Ore Pre-Feasibility study the company went on to be awarded the full feasibility study in 2021.

Joined Agbaou Mine as a Senior Mining Engineer and was promoted to Chief Mining Engineer 6 Months later and took responsibility for coordinating grade control and survey function input into mine operations and continued mentoring a team of Mining Engineers to develop core competencies necessary to provide technical support to the project and generate decision supporting information for mine management. I was from time to time called upon to provider leadership and mining technical support at Endeavour Mining's other operations, notably Hounde and Ity Mines.

• Re-designed the Pits, repositioned the ramping systems and haul roads resulting in review of the Life of Mine Load and Haul contract with initial cost reduction of $17 Million for Agbaou Gold Mine and significant improvement in operational efficiency of the mining contractor
• Conducted cost benefit analysis for the backfill of one of the satellite pits resulting in further projected saving of with $ 4 million off 2018 budget costs for Load and haul and a further $11 Million savings over the rest of the LOM
• Helped and mentored engineers, including one who would succeed me in the Chief Mining Engineer role, making it the first Section at Agbaou Mine to completely nationalize, after being led by expats

Worked on a number of client's projects in collaboration with geologists and mineral processing teams on and feasibility studies and operations optimisation. Projects tackled include;

• Polyus Gold International's Natalka Mine - Reserve audit, mine re- design for operational optimisation
• GV Gold - Resource audit, pit design and life of mine schedules for several projects but mainly Vysochaishy Mine and Ugakhan
• Mangazeya Mining -Pit optimisation, mine design and LOM schedule for Savkino mine
• First Nickel- Due diligence study of Lisbon Valley Copper mine
• Luna Gold- Pit Optimisation and mine design for Aurizona Gold Mine
• Beowulf Mining -Pit optimisation for resource definition of Kallack Mine

At this time AngloGold Ashanti was looking to implement the Deep Sulphides Mining Project and I hired to lead the planning team and preside over software packages migration to use of Surpac and MineSched.

• 
  
• The Training of a graduate mining engineers one of who went on to lead the team in later years till he sought pastures anew in the DRC.
• Successfully implemented migration from use of Datamine and Xpac for mine planning to use of Surpac and MineSched resulting in easily auditable schedules and reserve reports
• Prepared a schedule bring on stream the Tambali Pit which was successfully completed two months ahead of schedule
• Acting as Mine Technical Services Manager from January 2013 to June 2013

Was responsible for setting up a functioning mine planning department generated mining plans that resulted in turning the operation around to achieving its targets of 30kt of Copper cathode and 4.8tk of cobalt in hydroxide concentrate. Primary source of mined material was 3 open pits and an old Gecamines tailing dam

Was part of a multi-disciplinary technical services team that provided support and guidance to the mine operations team from Ground breaking up to successful commissioning of Lumwana Mine. Roles performed over three years include;

• Long term and strategic mine planning engineer
• Design engineer responsible for constructing the trolley assist ramp and lines
• Drill and Blast Engineering
• Short Term Planning

Hired as a Graduate Trainee Mine Planning Engineer and was exposed various units of the mine operation for a six month period after which I focused on a Mine technical services Development program during which time I gained exposure to grade control, and drill and blast QAQC best practice for optimal fragmentation
