• The Salamanqueja and Chacota mines consist of high-grade copper veins that are mined using sub-level stoping underground mining method.
• Ore is processed at our own SX-EW plant, which is adjacent to the Salamanqueja mine and has a nominal capacity of 11,000 tonnes of copper cathodes per year.
• The operation is developed with the highest ESG standards, receiving energy from a solar plant and water through SIAM.
• More than 80% of the workforce resides in Arica.

• The company produces 7,800 tons of copper cathodes per year and has a life of mine of 7 years.
• NI 43-101 resources of 4.3 MT @ 2.1%
• Work is underway on the 2022 resource update.

• 2021 EBITDA of US$35mm.
• Cash cost (C1) of US$1.95/lb places it in the 1st quartile of costs, being competitive with large-scale mining.

• Pampa Camarones is located in a district that has been historically under-explored.
• Management has identified over 10 targets in the vicinity of the operation.
• The potential of the district would allow for production to be raised to 25,000 tonnes of copper cathode per year.

The project is in the feasibility stage, which was completed in July 2021 with attractive economic results.
·       NPV: US$210mm
·       IRR: 29%
·       LOM: 16 years

• Over 40,000 meters of DDH (diamond drill hole) drilling have been carried out.
• The project has NI 43-101 resources of 10.1 MT @ 2.98% CuEq.

• The project has significant exploration upside that could double the existing resources.
• There are multiple options for its development.
• This allows to benefit from exposure to different commodities.

• Development of underground mining with minimal environmental impact.
• The project is located in an area without population and without communities.
• The EIA (Environmental Impact Assessment) to be submitted soon will include the use of wastewater in its production process.

• 13,000-meter DDH (diamond drill hole) drilling campaign completed.
• NI 43-101 inferred resources of 607,000 oz @ 6.1 g/t of Au.
• Potential resources of 300,000 oz @ 8 g/t of Au.

• Easy access to water and energy due to the presence of nearby high-voltage line and aqueduct.
• No communities nearby since the project is located in an exclusive mining district.

• The project has all the necessary developments, access and permits to implement a small-scale mining operation.
• The possibility of direct sales to ENAMI (Matta Plant) is being considered.

• Over a dozen veins have been identified with a total of 15 Km of strike length.
• Possibility to duplicate existing resources.

• A 2013 resource estimate determined an optimal cut-off grade of 17%.
• 743 Mt of inferred resources with an average grade of 28.57%.

• The project is located very close to an existing port with idle capacity.
• Indiana has access to railway facilities.

• PEA completed in 2013 by NCL Ingeniería y Construcción Ltd.
• Excellent economic results both for the Open Pit and Underground alternative.
• In 2017, Minería Activa updated PEA for the Underground alternative:
  – NPV: US$855mm
  – IRR: 20,2%
  – LOM: 22 years

• Management has a plan to develop the project in stages.
• Looking to achieve 2 Bt in Resources.
• Significant presence of scandium also offers opportunity in underdeveloped market.
