VANCOUVER, British Columbia, Sept. 28, 2020 (GLOBE NEWSWIRE) — Marimaca Copper Corp. (“Marimaca Copper” or the “Company”) (TSX: MARI) is pleased to announce it will host a webinar today at 11am EDT (8am Pacific; 4pm UK), following the release of the results of a high resolution, drone mounted, magnetic survey (the “Survey”) in the district surrounding the Company’s flagship Marimaca Copper Project (“Marimaca” or “the Project”) in Chile.

Questions can be submitted through the webinar platform, or via email to [email protected] no later than two hours prior to the scheduled start time.

The Survey has identified several large-scale magnetic anomalies which the Company believes are prospective for Marimaca IOCG style deposits.


  • Four large scale magnetic anomalies identified, believed to be prospective for Marimaca style deposits
    All similar size to or larger than the Marimaca Sulphide Target (175 million m3)

  • All targets are adjacent to key regional structures which are believed to control mineralization at Marimaca
    Regional structures clearly shown in magnetic survey results
    Naguayan Fault, whichcontrols Marimaca,clearly definedover 6km strike length
    Cross cutting faults, an important mineralization control at Marimaca, noted at all targets

  • Regional structure identified over 25km
    New ground staked andoption agreements executedcovering full extent of prospective structures
    Expanded magnetic surveys planned to identify additional targets for follow-up work

  • Three smaller targets on new fault structures,proximal to successful previous shallow scout drilling campaign

  • Potential for blind copper oxide mineralizationbeneath shallow gravel, as well aslarge scale sulphide targets

  • Cindy, Llanos and Mercedes Targets marked by highgrade, artisanal, copper workings
    A key feature of Marimaca

  • Improved understanding of Marimaca and its structural controls help to further refine the exploration model to target repetitions of Marimaca IOCG style mineralization

  • Follow-up work underway including IP surveys, surface geological work and drill hole planning
    Targeting drilling the Marimaca Sulphide Target in early 2021

Sergio Rivera, VP Exploration of Marimaca Copper commented:
“The clarity of the magnetic anomaly at Marimaca gave us a clear impetus to expand the size of our survey to identify new targetswithin our now expanded land package.The results are exceptional.There are several largescale magnetic anomalies adjacent to the important Naguayan Fault to the north of Marimacawhich exhibit similar geometry and spatial relationship with regional structures.Perhaps most exciting is that manyof the target areas are covered by gravel, suggestingthat any near surface oxide mineralization associated with these magnetic anomalies is likely to be blind.

We believe we have the potential to discover a new copper district in Chile and we are mobilizing geological teams for follow-up work prior to drilling.At the Marimaca Sulphide Target, we will complete an Induced Polarization survey to further define the best locations for drilling.Wewill also commence surface geological work to help prioritizethe new targets identified in the magnetic survey for follow-up work and we look forward to drill testing these as soon as possible.
