FORWARD LOOKING STATEMENT

These materials prepared by Evolution Mining Limited (or "the Company") include forward looking statements. Often, but not always, forward looking statements can generally be identified by the use of forward looking words such as "may", "will", "expect", "intend", "plan", "estimate", "anticipate", "continue", and "guidance", or other similar words and may include, without limitation, statements regarding plans, strategies and objectives of management, anticipated production or construction commencement dates and expected costs or production outputs.

Forward looking statements inherently involve known and unknown risks, uncertainties and other factors that may cause the Company's actual results, performance and achievements to differ materially from any future results, performance or achievements. Relevant factors may include, but are not limited to, changes in commodity prices, foreign exchange fluctuations and general economic conditions, increased costs and demand for production inputs, the speculative nature of exploration and project development, including the risks of obtaining necessary licenses and permits and diminishing quantities or grades of reserves, political and social risks, changes to the regulatory framework within which the Company operates or may in the future operate, environmental conditions including extreme weather conditions, recruitment and retention of personnel, industrial relations issues and litigation.

Forward looking statements are based on the Company and its management's good faith assumptions relating to the financial, market, regulatory and other relevant environments that will exist and affect the Company's business and operations in the future. The Company does not give any assurance that the assumptions on which forward looking statements are based will prove to be correct, or that the Company's business or operations will not be affected in any material manner by these or other factors not foreseen or foreseeable by the Company or management or beyond the Company's control.

Although the Company attempts and has attempted to identify factors that would cause actual actions, events or results to differ materially from those disclosed in forward looking statements, there may be other factors that could cause actual results, performance, achievements or events not to be as anticipated, estimated or intended, and many events are beyond the reasonable control of the Company. Accordingly, readers are cautioned not to place undue reliance on forward looking statements. Forward looking statements in these materials speak only at the date of issue. Subject to any continuing obligations under applicable law or any relevant stock exchange listing rules, in providing this information the Company does not undertake any obligation to publicly update or revise any of the forward looking statements or to advise of any change in events, conditions or circumstances on which any such statement is based.

This presentation has been approved for release by Evolution's Board of Directors.

Acknowledgement of Country

"Evolution would like to acknowledge the Traditional Custodians of the land on which we operate and on which we meet today, the Mitakoodi People, and pay our respects to Elders past, present, and emerging, for they hold the memories, the traditions, the culture and the hopes for Aboriginal people.

We acknowledge the elders for your resilience to pave the way for the generations after and we acknowledge those who continue to educate and empower to maintain and protect all aspects of Aboriginal heritage and culture."

  1. Original economic interest comprised 100% of gold and 30% of copper production within an agreed Life of Asset (LOA) area, and 49% of gold and copper production below the LOA area. Full ownership now comprises 100% of all gold and copper production from Ernest Henry. See ASX releases 'EVN Secures Full Ownership of Ernest Henry' dated 17 November 2021 and '"Full Ownership of Ernest Henry – Acquisition Completed" dated 6 January 2022 at www.evolutionmining.com.au

TRANSITION TO SLC UNDERGROUND MINE COMMENCED 2008

  • Construction of underground mine and associated infrastructure included:
  • 6km access decline – first cut taken Feb 2008
  • Construction of 75m high permanent headframe to house the hoisting system
  • 1km -deep shaft and ore hoisting infrastructure
    • Slew conveyor skip loading station
  • Underground primary crusher and ore handling system
  • UG ore pass and loader transfer network
    • 1.2km of underground and overland conveyors
  • Construction of mine ventilation and water management infrastructure
    • Twin 1.6MW Howden Primary Vent Fans
    • Initial 6MW chiller plant upgraded to 12MW in 2019
    • 230ML of underground water storage capacity
    • Pumping capacity of more than 40ML / day if required

EXCELLENT POTENTIAL FOR FURTHER GROWTH

  • Pre-feasibility Study (PFS) on a mine extension beyond FY26 underway due for completion end of calendar year 2022
  • Proposed mine extension from 1125RL to 775RL
  • Prior Concept Study extension was limited by geological knowledge which defined the 875RL as the battery limit for scope
  • Concept Study provided an additional 10 production levels
  • PFS will extend to 775RL using updated drilling and increased confidence, adding a further 4 production levels
  • Lowering the extension battery limit provides a balanced assessment of tailings storage requirements, subsidence, ventilation and materials handling
  • Further growth opportunity with mineralisation intersected 300m vertically below the PFS area and open at depth

CAVE REORIENTATION

  • EHO main cave orebody is changing shape with depth
  • Current longitudinal mining layout contains a reduced number of crosscuts at an extended length, impacting productivity and operational flexibility
  • A reorientation of the cave had been identified at the time of acquisition and was not considered a major operational risk
  • New orientation to the west requires capital development in FY23 and FY24 which will be completed before extension below 1200mRL commences
  • Mine development/infrastructure will be better positioned post cave reorientation
  • No material impact on production expected

EXCESS CONCENTRATOR CAPACITY

  • Current concentrator configuration capacity is ~8.5Mt with ~6.5Mt of feed from Ernest Henry
  • Options exist to fill excess concentrator capacity
  • Ore has been milled from four different sources since 2013 in dedicated campaigns
  • Historically contracts were structured to minimise risk with no performance guarantees provided and no grade risk assumed
  • Mt Colin ore is contracted to end of 2024 (450ktpa)
  • Option to reconfigure SAG mill feed infrastructure to streamline toll treating process
  • Currently evaluating other toll treating opportunities in the region

KEY TAKEAWAYS

World class infrastructure

Long history of successful operation as an open pit and underground mine

Extension below 1200mRL provides material additional mine life

Strong relationship with the community and Traditional Owners

TAILINGS CONFIGURATION

  • Turkey's Nest Tailings Dam Design
  • Capacity
    • ~3 million m3 at 15 March 2022 (~5 months storage)
    • South Cell construction underway, scheduled completion May 2022 – adding 18 months of additional storage
    • Upstream lifts completed every 14 months based on production rates
  • Future Tailings Dam construction
    • Currently under review through the PFS for LOM extension
    • Preliminary works suggest Tailings Dam can be lifted to provide sufficient storage for the mine extension down to the 775mRL

  2. Group Ore Reserve Competent Person (CP) Notes refer to: 1. Anton Kruger; 2. Mike Corbett (Glencore)

Note on the Ernest Henry December 2020 comparison: Prior to acquisition of full ownership of Ernest Henry (effective as of 1 January 2022), Evolution Mining had an economic interest earning rights to 100% of the revenue from future gold production and 30% of future copper and silver produced from an agreed life of mine area, and 49% of future gold, copper and silver produced from the Ernest Henry Resource outside the agreed area. The December 2020 Ernest Henry Reserve is reported here on the basis of economic interest and not the entire mine reserve. The reported December 2020 figures constitute 38% of the total Ernest Henry copper resource and 35% of the total Ernest Henry copper reserve.
