After including the effect of the Cost Support Agreement, the combined effect of the cash payments for gold and copper deliveries is as follows: Period: Jan. 1, 2024, through ~2029 ~2030 through ~2035 ~2036 and Beyond Au Cu Au Cu Au Cu Delivery Thresholds 1 defining triggers for cost support payments: (from Jan. 1, 2024) Pre-Threshold 2 (if Au<=$1,600/oz and Cu<=$3.50/lb) First Threshold (after the earlier delivery of either 375,000 oz Au or 30,000 t Cu) Second Threshold (after the earlier delivery of either 665,000 oz Au or 60,000 t Cu) Combined Effective Payments 3 : If Au<=$1,600/oz and Cu<= $3.50/lb: Lower of $850/oz, or 66% of spot Au 50% of spot Cu Lower of $850/oz, or 50% of spot Au 4 50% of spot Cu Lower of $1,050/oz, or 66% of spot Au 4 66% of spot Cu All other metal prices: $435/oz 15% of spot Cu Metal deliveries to Royal Gold typically occur up to 5 months after production at Mount Milligan due to the time required to ship concentrate from the mine site to the smelter and the payment provisions of the offtake contract. 1 Delivery Thresholds are defined by metal deliveries under the Existing Stream Agreement, which is independent from the Cost Support Agreement, and is used only as a reference for metal deliveries. 2 Pre-Threshold Support payments prior to the First Threshold are at Centerra’s option, and are recoverable from any cost support provided after the First Threshold is reached at metal prices above $1,600 per ounce of gold and $3.50 per pound of copper. 3 Includes the total amount payable per ounce of gold or pound of copper when the effect of the Cost Support Agreement is considered with the Existing Stream Agreement. 4 Given the relevant calculations, the cost support payments are only payable above a spot gold price of $870/oz after the First Threshold, and $660/oz after the Second Threshold. DEVELOPMENTS AND POTENTIAL Centerra is advancing a PEA to evaluate the substantial mineral resources at Mount Milligan with a goal to unlock additional value beyond its current 2035 mine life. The scope of the PEA is expected to include a review of significant drilled inventory to the west of the pit not currently included in the existing resource, and the inclusion of existing resources, most of which are classified in the measured and indicated categories. The PEA will also evaluate several capital projects to support a further mine life expansion, including options for a new tailings storage facility and potential process plant upgrades. The PEA is expected to be completed in the first half of 2025. Centerra is also continuing an exploration program aimed at expanding the mineral resource base significantly at Mount Milligan. At Goldmark and South Boundary, there are possibilities for near-surface additions. At North Slope, DWBX Extension and Saddle West, Centerra continues to test for depth extensions. Furthermore, Centerra is completing a comprehensive site-wide optimization program focused on assessments of health and safety, productivity and cost efficiency opportunities, in concert with mine plan optimization.
