Coro Mining Releases Marimaca Exploration Update

- February 19th, 2019

The company said the limits to the mineralization have not yet been defined and the lowest most workings at approximately 100m vertical depth are still in copper oxides.

Coro Mining (TSX:COP) has released an update for its Marimaca project in the Antofagasta region of Chile, where sampling of historic underground workings in the Sorpresa area approximately 2km to the south of Marimaca has confirmed the presence of a north-northeast oriented zone of intrusive hosted, copper oxide mineralization measuring at least 350 metres long by 100 metres wide.

The company said the limits to the mineralization have not yet been defined and the lowest most workings at approximately 100m vertical depth are still in copper oxides. Individual, well mineralized structures within the zone have widths of 10 to 40 metres. Like Marimaca itself, Sorpresa has not been previously drilled prior to Coro’s involvement.

As highlighted in the press release:

  • A total of 2,450 samples have been collected from underground workings, averaging approximately 0.50 percent copper with highlights including:
    • 77.3 metres at 1.0 percent copper
    • 17.0 metres at 2.70 percent copper
    • 53.2 metres at 1.01 percent copper
    • 32.2 metres at 1.09 percent copper
    • 15.0 metres at 4.20 percent copper
    • 54.8 metres at 1.16 percent copper
  • A reverse circulation (RC) drilling program with 12 holes for 3,000 metres is planned to test the strike and depth extent of the copper oxide mineralization.
  • Exploration in the area between the Marimaca deposit and Sorpresa is underway.
  • The presence of good grade mineralization at Sorpresa confirms the potential in the district, on ground controlled 100% by Coro.
