Expanded Chile Drilling Campaign Slightly Delayed
Marimaca Copper Corp. (TSX: MARI) has elected to expand its proposed drilling campaign at the Roble Target in Chile.
Roble is located less than 3km to the northeast of the company’s flagship Marimaca Oxide Deposit (MOD), and the company believes mineralisation may extend over 3km of potential strike.
VP Exploration, Sergio Rivera, said following further assessment of the Target area, the company has delayed the commencement of drilling at Roble primarily because the company elected to expand the drilling program at the Mercedes Target based on encouraging mineralisation observed in drilling, but also due to some delays caused by COVID restrictions.
Exploration Highlights
- Additional rock chip reconnaissance sampling at Roble has materially expanded the footprint of outcropping oxide mineralisation
- Mapped outcrop extends further north at Roble and south and east at Pele
- Extends strike potential to over 3km with widths at surface ranging from 300m to over 500m
- Three discrete areas of consistently outcropping mineralisation, each extending over approximately 600m by 400m, separated by gravel and sand cover
- Potential for connection of the larger Roble system through these covered areas
- Geophysics identified the continuation at depth of significant regional structures which control the location of mineralisation in the Marimaca district
- Interpreted structures are strongly coincident with surface trends of outcropping Cu oxide mineralisation with greater than 0.1% CuT
- Drilling to commence imminently at Roble with an initial 12-hole reverse circulation (RC) discovery drilling programme
- The Company has expanded the RC drilling campaign at Mercedes from nine holes to eighteen holes due to encouraging mineralisation intersected
- Resultant delay to the commencement of drilling at Roble, which is now expected during July
- Additional rigs planned for 2H 2021 based on expanded exploration programmes at Marimaca Depth Extensions, Cindy, Mercedes and Roble
“We have expanded our reconnaissance work at Roble which continues to indicate a potentially significant mineralised system, with outcropping mineralisation now extending over quite a broad 3km corridor of strike,” Mr Rivera said.
“It is highly unusual to identify an undrilled target, with extensive outcropping mineralization, in a mature copper jurisdiction like Chile.
“We have also completed Induced Polarisation (IP) surveys to complement the magnetics, surface reconnaissance and sampling work. This shows, quite clearly, the extensive north trending structural controls of the Roble Fault System are identifiable at depth.
“Notably, the resistivity anomaly is strongly coincident with the northern trend identified in the surface sampling work, highlighting a broad area of greater than 0.1% CuT coincident with the Roble Fault System and the magnetic anomaly identified in previous surveys.
“For IOCG deposits, large-scale structures controlling mineralisation are essential for forming more extensive systems, and we believe the indications are Roble could be a significant system.
“We have been delayed slightly in commencing our drilling campaign at Roble, but we are currently finalising our planning and infrastructure construction and expect to be drilling Roble during July.”
