Vancouver, British Columbia, January 16, 2019 – Marimaca Copper Corp. (“Coro” or the “Company”) (TSX: COP) is pleased to announce that it has entered into an option agreement to acquire a collection of 2% net smelter royalties at the Company’s Marimaca Project, thereby further consolidating its ownership over the project in advance of ongoing exploration results and the anticipated enlarged and integrated Marimaca resource estimate which is on track for completion in the third quarter of 2019.

Highlights

• Agreement favourably structured: minimal payments over 24 months, balance only in 36 months.
• Royalty areas optioned include
  • Atahualpa, where exploration results just released demonstrated copper oxide mineralisation
  • Tarso, where drilling due to commence
  • Additional early stage areas, notably Sorpresa I and II.
• The total option value of $2.2m for 2% royalties compares favourably to the buyback clause of $2.0m for 0.5% royalties in other Marimaca areas such as La Atómica and Olimpo North and South.
• Early agreement reduced risk of increased royalty cost as exploration program advances.
• As the exploration program advances and more resources are identified, royalties expected to increase in value

Commenting on the announcement, Luis Tondo, President and CEO of Marimaca Coppersaid: “I am pleased to announce that we have now an option to buy back all of the 2% NSR over some of the most prospective ground at our Marimaca Project. The ongoing excellent drilling results at Marimaca, notably those released this week at Atahualpa, are demonstrating the enlarged potential at Marimaca, and therefore it is wholly appropriate that we secure as much value for shareholders in the District now, ahead of ongoing exploration results.”

Option Agreement Information
The agreement is an irrevocable purchase agreement between the Company’s Chilean subsidiary, Minera Cielos Azul Ltda. (MCAL) and Capax S.A. The total cost is US$2.2m, divided over in 4 tranches over 36 months:
