	·	Paracatu is viewed as a long-term strategic asset for Kinross.
	·	The Morro do Ouro deposit is a metamorphic gold system with finely disseminated gold mineralization hosted within metasedimentary rocks.
	·	There is a good understanding of the geology and the nature of gold mineralization at the Project. The model represents the support data well, and is developed using appropriate resolution.
	·	The Mineral Resource estimate is of sufficient quality to support public disclosure and has been prepared using best practice guidelines.
	·	The current Mineral Reserves support the life of mine (LOM) until 2034.
	·	The mining operation demonstrates a high level of maturity, with well-established processes for reserve estimation, mine design, and production planning. The methodologies applied (e.g., Deswik scheduling, NPV optimization) are consistent with industry best practices.

	·	The integration of updated mineralogical data, real-time clay classification, and continuous hardness monitoring establishes a robust framework for optimizing the Paracatu processing circuit. These measures improve recovery, reduce variability, and support long-term operational efficiency.
	·	KBM maintains consistent social engagement efforts and implements projects in line with community needs.
	·	KBM conducts regular water quality and acid rock drainage management practice reviews, with the assistance of third-party specialists. KBM regularly conducts follow-up test work and updates the operation’s practices in accordance with the findings of these reviews.

	1.	Continue to evaluate opportunities to strategically stockpile lower-grade material and optimize processing schedules under scenarios of higher metal prices, aiming to support Mineral Reserve growth and extend the LOM without lowering cut-off grades.
	2.	Investigate the significant resource base given elevated metal prices.
	3.	Continue maintaining the environmental and social management systems and procedures to comply with legal requirements and update the closure plan as needed.
	4.	Continue social engagement and projects in line with community needs.
	5.	Continue to conduct regular water quality and acid rock drainage management practice reviews and implement improvements to water quality management practices in alignment with the recommendations compiled during these reviews.
