Announcement summary: Sunstone Metals Ltd (ASX: STM) is pleased to announce that the latest assays at El Palmar continued to expand the area of known mineralisation and reveal significant higher-grade zones of >0.2% copper and 0.35g/t gold. The results demonstrate that El Palmar now has substantial scale and grades which are in line with those seen in many of the world’s high-profile porphyry deposits, including those nearby such as Alpala and TandayamaAmerican described below. El Palmar is located in northern Ecuador in the same regional structural belt that hosts the 2.66Bt Alpala copper-gold deposit grading 0.25g/t gold and 0.37% copper, and the 0.53Bt Tandayama-America deposit grading 0.19g/t gold and 0.24% copper, within the Cascabel project (Figures 4 & 5; see for MRE details), and in the vicinity of the 1Bt Llurimagua copper-molybdenum porphyry deposit grading 0.89% copper and 0.04% molybdenum. The El Palmar results reported in this release comprise all assays from drill holes EPDD0012, 013, 014, 015 and 017, with intersections primarily in the upper 500m zone of the eastern sector of the main El Palmar target (Figure 1 and Table 1).

It intersected strongly mineralised intervals in shallow domains and several intervals between 673.5m and 1087m of anomalous gold, copper
