Cornerstone Capital Resources Inc. provided an update on its Bramaderos gold and copper joint venture in southern Ecuador in which it has a 12.5% interest carried by JV partner and project operator Sunstone Metals Inc. through to the start of commercial production. Highlights: Drilling at Espiritu has intersected more high-grade silver with gold, zinc and lead within a polymetallic epithermal system. Drill hole ESDD006 intersected 5 significant lodes of silver-gold-zinc-lead mineralization, including: 102.25m to 106m; 3.75m at 11.77g/t silver, 1.54g/t gold; 172.75m to 173.15m; 0.4m at 355g/t silver, 0.36g/t gold, 3.55% zinc; 206.15m to 206.65m; 0.5m at 187g/t silver, 1.44g/t gold; 277.5m to 278.0m; 0.5m at 550g/t silver, 0.26g/t gold; 313.0m to 313.5m; 0.5 at 93g/t silver, 0.68g/t gold, 2.45% zinc; Hole ESDD008 was just completed at 359.97m, intersecting altered and silver-lead-zinc bearing zones, adding significant scale to the system with a strike extent now of over 200m. Hole ESD009 commenced. A significantly larger system at Espiritu is emerging based on mapping, soil sampling, interpretation of geophysics, and ongoing drilling. Narrow high-grade zones and intervening lower grade zones can be bulked and outline larger mineralized bodies. Drilling on the Brama gold-copper porphyry target is expected to commence the first week of February. The drill hole is targeting a magnetic anomaly below a mineralized breccia interpreted to represent a `pencil porphyry' gold-copper target. Assay results and geological interpretation from hole ESDD006 show multiple silver-gold bearing structures with various orientations. Drilling of hole ESDD008 has been completed at 359.97m and has intersected altered and mineralized intervals that indicate increasing confidence in the interpreted geometry and that the Espiritu discovery has the potential to be a large system with currently over 200m of strike containing local bonanza grades. On a gold or silver-equivalent basis, the intersections reported are significant. Drill hole ESDD009 has been commenced and is targeting an area 250 south of ESDD008. Drilling to date has only tested to a depth of ~250m below surface in two locations at Espiritu. Evidence of multiple lodes means there are several opportunities to follow-up bonanza grades across the area drilled to date. Narrow high-grade zones and intervening lower grade zones can be bulked and outline larger mineralized bodies. Both concepts are being explored ­ high grade narrow veins and larger lower grade systems. Drilling of the Brama porphyry gold-copper system is expected to commence in early February 2021. The target at Brama is a `pencil porphyry' as interpreted from 3-D modelling of magnetics data. The drill hole will test beneath a well- mineralized potassic altered high level intrusive breccia zone of the Brama porphyry intersected in earlier drilling and returning 98m at 0.61g/t gold and 0.11% copper in BMDD005 and 103.6m at 0.56g/t gold and 0.13% copper in CURI 13. The drill hole will be drilled to 900-1000m and is expected to be completed in early March.
