Disclaim er & Forw ard Looking Statem ents

This presentation includes certain forward-looking statements about future events and/or financial results which are forward-looking in nature and subject to risks and uncertainties. Such forward-looking statements or information, including but not limited to those with respect to the operation of SCM Berta, and the development of the Marimaca project, metal prices, metallurgical results and resource estimates, involve known and unknown risks, uncertainties, and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements or information. Forward-looking statements include without limitation, statements regarding the company’s plans, goal or objectives and future completion

  • f mine feasibility studies, mine development programs, capital and operating costs, production, potential mineralization, resources and

reserves, exploration results and future plans and objectives of Coro Mining Corp. Forward-looking statements can generally be identified by the use of forward-looking terminology such as “may”, “will”, “expect”, “intend”, “estimate”, “anticipate”, “believe”, or “ continue” or the negative thereof or variations thereon or similar terminology. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause results to differ materially from expectations include risks associated with mining generally and pre-development stage projects in particular. The company is an exploration, development & mining company. Many references to resources and other geological and technical information contained herein have not been verified by an independent expert and are either not in accordance with the requirements under National Instrument 43-101 or have not been prepared in accordance with a preliminary or final feasibility study. Potential investors should conduct their own investigations as to the suitability of investing in securities of Coro Mining Corp. The potential target tonnage and grade noted for the El Jote project are conceptual in nature as there has been insufficient exploration to define mineral resources, and it is uncertain if further exploration will result in these targets being delineated as mineral resources. Unless otherwise indicated, Coro has prepared the technical information in this presentation (“Technical Information”) based on information contained in the technical reports and news releases (collectively the “Disclosure Documents”) available under Coro Mining Corp.’s company profile on SEDAR at www.sedar.com. Each Disclosure Document was prepared by or under the supervision of a qualified person (a “Qualified Person”) as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators (“NI 43-101”). For readers to fully understand the information in this presentation, they should read the Technical Reports (available on www.sedar.com) in their entirety, including all qualifications, assumptions and exclusions that relate to the information set out in this presentation which qualifies the Technical Information. Readers are advised that mineral resources that are not mineral reserves do not have demonstrated economic viability. The Disclosure Documents are each intended to be read as a whole, and sections should not be read or relied upon out of context. The Technical Information is subject to the assumptions and qualifications contained in the Disclosure

  • Documents. All figures are quoted in US dollars unless otherwise stated.

Copper in Chile

  • Chile is the world’s largest copper producing country
  • Safe, low political risk
  • History of mining and mining-friendly government
  • Defined process for project approval
  • Long history of foreign investment
  • Leachable Copper
  • A significant percentage of Chilean production comes from so-called leachable

deposits, either by heap leaching where higher grade material is crushed and deposited on a lined heap leach pad; or run of mine leaching of lower grade material where the ore is not crushed prior to depositing on a lined pad

  • The copper is extracted from the pads by means of dissolution by sulphuric acid to

form a pregnant leach solution (PLS), followed by solvent extraction and electro- winning (SXEW) to produce copper metal in the form of 99.99% Cu cathodes

Our Business

Coro discovers, develops and operates high return, low cost, low capital intensity, leachable copper deposits in areas of good infrastructure in Chile.

  • Marimaca: Exciting New Development Project: (Coro earning 75% )
  • Open pit mineable, heap leach project with maiden resource estimate
  • 145,500t of Measured & Indicated + 99,300t of Inferred contained copper resources
  • Deposit remains open in 3 directions
  • Unbeatable location, low strip ratio and good metallurgy
  • Finalising acquisition of nearby 10,000t per year Cu Ivan SXEW processing plant
  • SCM Berta: Expanding Production: (Coro 65% )
  • Berta open pit mine, 3,000t per year Nora SXEW processing plant & El Jote project
  • Finalising installation of leaching facilities at Berta & expansion to 4,800t per year
  • El Jote provides potential for further expansion or life extension
  • Strong Partners
  • Greenstone Resources (61% of Coro). Private equity group investing in companies with

small to medium sized projects approaching production

  • ProPipe (35% of SCM Berta). Chilean engineering company focussed on driving down

capital and operating costs. Project development team for Coro

  • “Coro type” projects have the following characteristics:
  • Stage of development immaterial, preferably open pit, preferably leachable
  • Close to infrastructure & water
  • Environmentally simple & socially acceptable
  • Financeable relative to our market capitalization
  • Readily scalable with additional exploration
  • We will then develop them in the “Coro way” by:
  • Having an austerity-driven development approach
  • Accelerating commencement of production
  • Minimising initial capital investment rather than maximising NPV
  • Prioritising profitability over production rate

Our Growth Strategy

Using our exploration and development expertise, our strategy is to grow a Chilean copper mining business through the discovery, development and operation of “Coro

type” projects. Our target is to be producing more than 30,000t per year Cu within 5 years.

Marimaca: Geology and Mineralization

  • Deposit hosted by Jurassic age coarse grained dioritic rocks, strongly affected by E

dipping N-S oriented fracturing related to a branch of the Atacama Fault Zone, the Marimaca Structure

  • Subsequent SE dipping, NE-SW oriented feeder structures, possibly Riedel shears

associated with NW-SE shearing, introduced copper mineralization

  • Mineralization genetically associated with late Jurassic plugs, sills and dykes which

controlled distribution of primary sulphides

  • Primary mineralization consists of hairline to centimetric veinlets of chalcopyrite-

magnetite with accompanying potassic alteration. Very little disseminated sulphide

  • Supergene enrichment with chalcopyrite enriched to chalcocite and covellite
  • Deep oxidation and Cu remobilization resulted in an oxidised enrichment blanket
  • Distribution and grade of secondary copper mineralization controlled by fracture density
  • Pyrite halo developed in hanging wall of deposit, oxidised to pyritic leached cap

Plan Cross Section

  • Potentially open pit mineable deposit located 30km NNW of Nora
  • Potential for 8,000,000t at 0.5-0.6% CuT* , heap leachable, based on 56 RC holes
  • Bottle roll test work indicates 70% recovery of CuT with 20kg/t acid consumption
  • $1,500,000 budget to reach PFS stage.
  • Outstanding $2,500,000 in option payments to acquire 100%

* The potential quantity and grade is conceptual in nature, being based on limited drilling surface sampling and mapping, there has been insufficient

exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
