The gold stream agreement will cover all copper produced from the area of interest shown as the “RGLD Gold AOI” in the AOI map below, an area of approximately 31 square kilometers. If the gold stream delivery is not received by May 21, 2033, and RGLD Gold AG does not terminate the gold stream agreement, the area of interest will expand to the “RGLD Gold Expanded AOI,” an area of approximately 186 square kilometers. RGLD Gold AG holds an incremental NSR royalty (the “Royalty”) over all metals produced from within the RGLD Gold Expanded AOI at an initial rate of 0.30%. The Royalty rate will increase by 0.0375% per year until the earlier to occur of the first delivery under the gold stream agreement or May 21, 2033, to a maximum of 0.60%, subject to certain scenarios: • If the Solaris Option is exercised, the full 0.60% royalty rate will vest for the LOM. • If the RG AG Option is exercised, the incremental Royalty rate earned at the time of exercise will vest for the LOM. For example, if the RG AG Option is exercised in 2030, the Royalty rate will be 0.49%. If the RG AG Option is exercised and the gold stream agreement is terminated, the royalty area of interest will decrease to the smaller RGLD Gold AOI. If ore from outside the royalty area is commingled and processed at Warintza, all ore processed is subject to the royalty agreement until 11.5 billion pounds of recovered copper have been produced. If Solaris sells any property located outside the boundaries of the RGLD Gold AOI but within the RGLD Gold Expanded AOI while the gold stream agreement remains in effect, the gold stream agreement will no longer extend to those properties, but RGLD Gold AG will immediately vest in a 1.2% royalty over the property sold.
