[{"type":"text","content":" VANCOUVER, British Columbia, March 28, 2022 (GLOBE NEWSWIRE) -- Marimaca Copper Corp. (“Marimaca Copper” or the “Company”) (TSX: MARI) is pleased to announce results from the first seven (7) reverse circulation (RC) drill holes, totaling 2,150m, from the 2022 infill drilling campaign at the Marimaca Oxide Deposit (“MOD”). The first drill holes were completed in the south-eastern area of the MOD in an area previously considered to be on the margin of the near-surface oxide copper mineralization. The drilling intersected broad zones of near-surface green copper oxide mineralization in six out of seven holes. Importantly, several zones appear to be extensional to the existing Mineral Resource Estimate (MRE) (released December 2019) for the MOD, and the interpretation of the new mineralized intersections indicates that the MOD remains open at depth and to the south-east, indicating potential upside with ongoing drilling in this area. A video is available with Hayden Locke, President & CEO, discussing today’s results. Highlights Expected mineralization encountered in six out of seven holes with grades often exceeding those modelled in MRE MAR-134 and MAR-132 extend mineralization into areas previously interpreted to be barren or lower-grade Expected to have positive implications for the updated MRE Notable intersections include: MAR-134 intercepted 106m of 0.53% CuT from 2m, including 28m of 1.05% CuT from 72m MAR-132 intercepted 54m of 0.62% CuT from 80m and a high-grade feeder structure of 20m at 1.62% CuT from 278m at the bottom of the hole, all within a broader intercept of 226m of 0.43% CuT from 72m MAR-135 intercepted 58m of 0.41% CuT from 2m MAR-131 intercepted 202m of 0.31% CuT from 42m, including 74m of 0.47% CuT from 162m MAR-133 intercepted 76m of 0.26% CuT from 156m MAR-129 intercepted 58m of 0.27% CuT from 68m MAR-130 intercepted lower grade copper mineralization corresponding to leached and fractured rocks along a known late fault zone Drilling continues to highlight the lateral continuity as well as the thickness of the MOD mineralized column as well as ongoing potential for extensions at depth The MOD remains open to the southeast towards the Sierra satellite target, located 400m southeast from the margin of the MOD (see Figure 5 and announcement dated January 20, 2022) Sergio Rivera, VP Exploration of Marim...
