| ABSTRACT: | Sunstone Metals Limited (ASX:STM) is pleased to announce assay results from its second hole (LMDD002) at the Limon prospect and visual results from the first hole it has drilled (BMDD001) at the Bramaderos Main prospect. Both prospects are within the Bramaderos project in southern Ecuador. As described in the ASX release dated 29th May 2019, hole LMDD002 intersected an interval of porphyryrelated mineralisation with visible and persistent chalcopyrite (copper sulphide) and molybdenite (molybdenum sulphide), minor bornite (copper sulphide), anhydrite veining and widespread pyrite in quartz stockwork B-veining in the lower parts of the drill hole. This is interpreted to indicate that the intersection lies within the peripheral halo adjacent to the main core of the porphyry system where there is most likely to be significantly further enhanced accumulations of copper and gold. The assay results from LMDD002 are entirely consistent with this geological interpretation and provide strong support for targeting the next hole at Limon approximately ~300m to the east of hole LMDD002 (Figures 1 and 2). The first hole at the Bramaderos Main porphyry target, BMDD001, has been completed at 669.45m down-hole (Figure 3). It was drilled approximately 50m below the historical intersection of 248m at 0.56g/t gold and 0.14% copper obtained from near surface in hole CURI-03 (drilled to a depth of 257.24m in NovemberDecember 1999 by Paragon del Ecuador for Ecuanor), and below a surface longitudinal trench that delivered 615m at 0.52g/t gold and 0.11% copper (refer to ASX announcement dated 9 May 2018). Based on visual inspection, the geology in BMDD001 appears to correlate well with that reported from the historical hole in the upper 250m. Below this depth, in BMDD001, intense quartz veining in altered intrusive rocks (Plates 1 and 2) suggests that the mineralisation extends to a depth of approximately 600m down hole and well beyond the end of hole CURI-03 (see Figure 3). | |
