Here's the FY27 budget stacked bar chart for all three production metrics across the 12 months. A few key observations:
Fleet: 9 haulers × 1,200 tph = 10,800 tph · Operating hours: 15 hrs/day · Daily capacity: 162,000 tons/day · Rain impact: 6 days/month, Nov – Mar
The FY27 budget is not achievable with the current fleet configuration. Only 3 of 12 months (April, June, and January) have sufficient hauling capacity, while 9 months show deficits. The cumulative annual shortfall is ~2.66 million tons, requiring an additional 246 fleet-hours beyond the budgeted operating regime - equivalent to roughly 16.4 extra full operating days across the year.
The most critical months are the wet season (Nov–Mar), where rain day losses and still-significant budget targets create severe pinch points. November and February are the worst at 644k and 568k tons short respectively. However, July and August alone account for 921k tons of shortfall due to elevated waste stripping targets (budget exceeds 5.46M tons in both months).
The shortfall becomes structural from July onwards. The small surpluses in April and June (~239k tons combined) are consumed by May's minor deficit, and from July the cumulative gap only widens - crossing 246k tons in July, 1.13M by October, and accelerating through the wet season to 2.66M by year-end.
All four outputs are now on your dashboard. Here's the comparative summary:
Reducing daily operating hours by just 36 minutes per hauler eliminates 2,170,800 tons of annual fleet capacity - more than two million additional tons the fleet can no longer move. This pushes the FY27 annual shortfall from 2.66Mt to 4.83Mt, almost doubling it.
| 15 hrs/day | 14.4 hrs/day | |
|---|---|---|
| Annual capacity | 54.27 Mt | 52.10 Mt |
| Budget requirement | 56.93 Mt | 56.93 Mt |
| Annual shortfall | 2.66 Mt (4.7%) | 4.83 Mt (8.5%) |
| Fleet hours gap | 246 hrs | 447 hrs |
| Equivalent extra days | ~16.4 days | ~29.8 days |
Bottom line: at 15 hrs/day the budget is technically possible with targeted interventions (extended shifts in Jul–Aug, tighter scheduling in the rain season). At 14.4 hrs/day the budget is fundamentally undeliverable - you would need the equivalent of an entire extra month of production somewhere in the year. The 36-minute daily difference is not a minor scheduling tweak; it represents the margin between a challenging-but-possible target and an impossible one.
