| ABSTRACT: | Stellar Resources Limited (ASX: SRZ, “Stellar” or the “Company”) is pleased to announce significant tin assays for ZS137 (see Table 1). The DDH provided in-fill on cross-section 3700N and intersected three zones of tin mineralisation with the most significant being 5m at 0.6% tin from 447m down-hole. The three intersections correlate with similar zones 50m up dip in ZS123 and 70m down-dip in ZS81 (see Figures 3, 4 and 5). In addition to the significant intervals summarised in Table 1, ZS137 intersected tin bearing alteration veins and replacement textures over 146m down-hole from 323m. This broad halo of mineralisation represents a major system characterised by multiple pulses of tin bearing fluids of varying chemistry and following a range of structural orientations. Chlorite, siderite, quartz, pyrrhotite, pyrite, talc and tourmaline with associated cassiterite make up the alteration minerals that obliterate most of the original rock texture. The drill core shown in Figure 1, is characterised largely by replacement textures with only a moderate level of sulphide veining. Where veins occur, they commonly dip steeply and strike along one of three major orientations; north-south, northwest-southeast and northeast-southwest. Cassiterite bearing pyrrhotite-quartz and pyrite quartz veins can be found in all three orientations. However, north-south is the most frequent vein orientation and for that reason may contain more tin than the other orientations. In ZS137, vein chemistry may also play a role in determining tin grade as more tin appears to be associated with pyrrhotite-quartz veins than pyrite-quartz veins. The timing of pyrrhotite-quartz veins relative to pyrite-quartz may also be important but the ambiguous evidence of vein timing makes such a determination difficult | |
