­ Marimaca Copper Corp. announced that drilling results from the remaining reverse circulation ("RC") drill holes, completed at the Cindy Target ("Cindy"), have intersected significant copper mineralization, extending the strike length to over 800m. Cindy is located less than 5km to the north of the Marimaca Oxide Deposit ("MOD") and offers potential to add to the Company's leachable resource base and extend mine life or increase the scale of future operations. The initial drilling campaign at Cindy (located less than 5km to the north of the MOD) consisted of nine, shallow, RC drill holes targeting the anomalies identified in both the magnetic survey and surface geochemical sampling previously completed. The objective was to identify new, broad zones, of shallow oxide mineralization that could complement the existing resources at the MOD, and potential deeper sulphide bearing structures which could indicate a more extensive copper system. Results from holes CIR-01, CIR-02 and CIR-03 were released on June 15th, 2021. The nine holes were drilled on approximately 250m section lines to the north and south of the historical underground workings at Cindy, extending over roughly 1.2km of strike. Two sections, located in the northern part of Cindy, each consisted of two drill holes, and tested the interpreted broadening of the various structures, which are believed to be key controls of mineralization at Cindy. The first three drill holes intersected broad zones of copper mineralization over a step-out strike of roughly 800 meters. Drill holes CIR-03 and CIR-02 intersected broad zones of mixed copper oxide material from near surface including 40m with an average grade of 0.51% CuT from 48m downhole and 20m with an average grade of 0.33% CuT from 8m downhole, respectively. Drill holes CIR-08 and CIR-09 both also intersected broad zones of copper mineralization, interpreted to be the same easterly dipping geological structures observed in CIR-01, CIR-02 and CIR-03, giving a total strike of 800m. CIR-08 was a step out approximately 200 meters to the north of CIR-01 and 400m to the south of CIR-02. It intersected 100m of copper mineralization with an average grade of 0.3% CuT from 128m downhole. This included a higher-grade zone of 42m with an average grade of 0.46% CuT. The mineralization was dominantly enriched in the top part of the intersection transitioning to dominantly chalcopyrite at the bottom. CIR-09 stepped out approximately 200m to the north of CIR-08. Again, it intersected broad zones of copper mineralization including 122m with an average grade of 0.23% CuT from 218m downhole. Mineralization was dominantly chalcopyrite with some minor mixed and green oxides. The depth of the intersection, and the nature of the mineralization observed in the drill holes, indicates it corresponds with a lower section of the easterly dipping structures which are the controls of mineralization at Cindy. Based on this interpretation, the Company believes that there remains strong potential for up dip extensions with a higher proportion of leachable oxide mineralization. The Cindy drilling has identified an easterly dipping structure with a continuous strike of around 800m with broad and consistent zones of mineralization. Drill holes located further to the west (e.g. CIR-02 and CIR-03) have intersected near surface zones of oxide mineralization. Those holes located further to the east (e.g. CIR-01, CIR-08 and CIR-09) have hit mixed, enriched and primary mineralization at greater depth, indicating good continuity of mineralizing structures across the target area. The Company has extended the drone mounted, high resolution, magnetics survey to the areas directly to the north of Cindy, which has identified several interesting magnetic anomalies which appear to be closely related with the regional Naguayán Fault System. The Mititus Target is coincident with one of the anomalies identified and is located less than 500m to the north of Cindy and may represent its northern continuation. Marimaca Copper will continue to assess the Mititus Target and its potential to add additional strike to Cindy with ongoing work.
