OPPORTUNITES, RECOMMENDATIONS AND RANKINGS
PRIORITY 1
GEOLOGY
Implement Estimation of Au grades based on litho-chem domains in all models.
Apply machine learning models for dynamic updating of litho-chem domains for GC, medium term and resource models.
Review and add chip, daily face, and bench mapping to the structural and litho-chemical models
-
Develop and implement medium-term model to cover subsequent planned quarter, updated monthly using the same geochemical domains.
Revisit top cuts based on geological continuity and litho-chem domains. Compare to current top cuts (based on past recon) and implement in all models.
-
-
Add density, geomet variables and moisture models as they become available.
-
Define Robust blast hole sampling process and ensure consistency in execution of procedure with help of external specialist.
-
-
GEOTECHNICAL
Structural Mapping:
-Enhance and perform structural mapping soon after benches are exposed. Collect and process data to evaluate potential impact on next lower benches.
-Update large scale structural model
-
-
-
Mine Operation Aspect:
Plan for double side loading
Develop schemes of deployment configurations in all mine plan/execution
Use video data and dispatch data to enhance supervisor and operator awareness. Through supervisor training programs, effective field and remote supervision should be implemented.
-
Strategic Planning
Ensure adequate level of confidence of all aspects that are to be incorporated into 2022 plan
Fast track and determine Design criteria for LOM
Perform a thorough examination of bulk mining options versus mixture of bulk/selective mining
Site Costs:
Evaluate early transition of 795
Perform assessment of preferred operation practice:
-bulk vs bulk/selective.
-understand cost of dilution in cross-mine processes
-understand cost of selective vs. bulk mining.
assess cost of escalation impacts (capital and operating) in cross-mine areas.
PRIORITY 2
Geological:
-Standardize on consistent resource model approach for all pits
-Develop additional studies based on conditional simulations:
--Uncertainty estimates in current resource and reserve classification
--uncertainty of resources and reserve in grade-tonnage curves
--Mine plan and Schedule uncertainty and bottle neck
dilution and ore loss estimates.
-See if use of info from exploration can speed development of geoemt model.
-Evaluate use of mineralogical model (ore/gangue) to help predict plant recoveries.
-Complete cost benefit on blast hole sampling and BH based GC models after possible refinement to gc system have been introduced.
Geotechnical:
Review south Wall Design:
-Collect and review photogramtery data for south wall
-Use DFN models to develop bench and inter scale charts relating tthe probabnility of failure to bench face or inter-ramp angel
After 2022 LOM pit shell is generated, evaluate potential impact of Talc and UG openings.
Rock Fall Tests and Rockfall model
29m Vertical pre-shear North Wall-continue to collect data on blast hole deviations, actual crest back break and effective BFA and bench width.
Rock testing-direct shear testing on joint/fault materials
-
Mine Operation Aspects:
-Interact with planning group to plan for efficient configuration,
Effective Road widths
Perform Congestion monitoring and apply mitigation measures
Mine Planning Aspects:
-Re-asses preferred SMU considering all other objectives. Perform overall assessment between bulk and semi selective mine operations considering all cross mining disciplines
-Assess alternative intersection layouts and incorporate in future designs. Design for traffic flow (use congestion analysis from dispatch data)
-*Target reduction in re-handle:
-understand justify reasons for re-handle
-identify lowest cost method of of re-handle
-assess strategic options
Consider Five year business plan as primary business plan with higher level of assessment and level of reporting.
Strategic Planning:
-Position mine plan for future autonomous and remote control fleet
-Proceed with trolley on south dump trial
-Challenge trolley traffic density assumptions.
-Update cost model for different strategic alternatives considering cost escalation impacts
