Mirasol Resources Ltd. (TSXV:MRZ,OTCPK:MRZLF) reported additional intersections of gold and silver mineralization from its Phase II drilling at the Curahue Trend in the Claudia project, located in Santa Cruz Province, Argentina.
As quoted in the press release:
Assay results from Phase II drilling (Table 1) show 0.6 to 1.8 m wide zones of higher-grade Au+Ag within a broader zone of lower-grade mineralization that ranges in width from a few metres to a maximum true width of up to 60 m wide. Au+Ag mineralization reports to a large zone of mapped and drill-intersected low sulphidation epithermal veins and veinlet halos. The mineralization shows variable Ag:Au ratios but is often silver-dominant with Ag:Au ratios in some intersections exceeding 1,000:1. To assist in visualizing the Au+Ag assay results, they are presented as both Au and Ag assays and as an AuEq60* (Au equivalent) value. Selected higher grade intervals from the Phase II drilling include:
- 0.6m at 11.72 g/t Au and 1,224 g/t Ag (0.6m at 32.13 g/t AuEq60)
- 1.0m at 5.59 g/t Au and 199 g/t Ag (1.0m at 8.92 g/t AuEq60)
- 0.6m at 1.48 g/t Au and 1,448 g/t Ag (0.6m at 25.62 g/t AuEq60)
Selected broader intervals of lower grades, at 0.3 g/t AuEq60 cut off include:
- 16.3m at 0.75 g/t Au and 75.9 g/t Ag (16.3m at 2.01 g/t AuEq60)
- Including 2.2m at 2.89 g/t Au and 135.8 g/t Ag (2.2m at 5.15 g/t AuEq60)
- 15.9 m at 0.52 g/t Au and 77.2 g/t Ag (15.9 m at 1.81 g/t AuEq60)
- Including 3.9m at 1.90 g/t Au and 166.3 g/t Ag (3.9m at 4.67 g/t AuEq60)
- 9.3m at 1.40 g/t Au and 134.6 g/t Ag (9.3 m at 3.65 g/t g/t AuEq60)
including 3.0m at 3.16 g/t Au and 332.6 g/t Ag (3.0m at 8.71 g/t AuEq60)
Mirasol’s preliminary cross section interpretations (Figures 3 and 4) shows a âpinch and swellâ shape to the mineralized zone, typical of epithermal veins. These mineralized shoots within the vein zone, can develop both along strike and down-plunge depending upon the sense of movement (displacement) along the vein-controlling structure. At âIoâ the mineralized zone can be unusually wide reaching interpreted maximum widths of up to 60 m. Mineralization starts within a few metres of surface, as bedrock is covered by thin, unconsolidated post-mineral gravel cover, and has been tested to depths of 135 m below surface. The preliminary interpretation of the âIoâ Zone suggests the mineralized body may dip at between 60 and 80 degrees to the southwest.
