ADDITIONAL RESOURCE DRILLING RESULTS CONFIRM CONTINUITY OF HIGH-GRADE SILVER AT THE BOWDENS DEPOSIT

Highlights

  • Drilling confirming continuity of high grade silver mineralisation and extending Bowdens Silver resource at depth.

  • Results include;

  • 129.0 metres @ 89g/t silver, 0.15% zinc and 0.28% lead (103g/t silver equivalent) from 72 metres down-hole including;

  • 45.0 metres @ 143g/t silver, 0.20% zinc and 0.50% lead (168g/t silver equivalent) from 103 metres down-hole; and

  • 1.0 metre @ 2370g/t silver, 0.89% zinc and 1.90% lead (2465g/t silver equivalent) from 235 metres down-hole.

  • 2.2 metres @ 433g/t silver, 5.10% zinc and 2.80% lead (695g/t silver equivalent) from 23.8 metres down-hole.

  • Further results are pending.

  • Drilling is on-going with two rigs operational.

Drill Program

Silver Mines Limited (ASX:SVL) (“Silver Mines” or “the Company”) is pleased to advise that it has received the drill results from a further four holes (BD16007-009 & BD16015) of a 38,000 metre drill program at the Bowdens Silver project located near Mudgee in New South Wales.

Holes BD16007, 008, 009 and 015 were designed to test both the continuity of high grade silver mineralisation and for depth extensions along the eastern portion of the Bowdens Silver resource. This eastern portion of the deposit is referred to as “Main Zone”.

Hole BD17002 was designed to test for the continuity of deeper mineralisation along the western portion of the Bowdens Silver resource. The western portion of the deposit is referred to as “Bundarra”.

The results from BD16007 72 metres to 148 metres down hole confirm the high-grade silver mineralisation from this portion of the resource and in addition, the interval from 148 metres to 201 metres down hole extends the current resource by up to 50 metres vertically. Furthermore, the high-grade interval from 235 metres in BD16007 is among the highest assays received for the project. Such high-grade structures at the Bowdens Silver deposit continue to provide encouragement for potential underground development scenarios in addition to the open pit development subject to the current Definitive Feasibility Study. The results from BD16008 which remain open to end of hole (252.6 metres) indicate that the mineralised system extends for up to 100 metres directly beneath the current resource.

The mineralisation is hosted within felsic welded tuffs of the Permian aged Rylstone Volcanics, generally consisting of close-spaced base-metal sulphide and silver bearing veins and basemetal sulphide breccias.

Please refer to Table 1, Figure’s 1 and 2 and Appendix 1 for further details.

The current drill program involves infill drilling to convert inferred resources to measured and indicated resource categories as well as testing for potential extensions of the known mineralisation. The total program, consisting of 178 holes for 38,000 metres of drilling will be a combination of diamond core and reverse circulation drilling.

About the Bowdens Silver Project

The Bowdens Silver Project is located in central New South Wales, approximately 26 kilometres east of Mudgee (Figure 3). The recently consolidated project area comprises 1,654 km[2] (408,000 acres) of titles covering approximately 80 kilometres of strike of the highly mineralised Rylstone Volcanics. Multiple target styles and mineral occurrences have potential throughout the district including analogues to Bowdens Silver, high-grade silver-lead-zinc epithermal and volcanogenic massive sulphide (VMS) systems and copper-gold targets.

Bowdens Silver is the largest undeveloped silver deposit in Australia with substantial resources and a considerable body of high quality technical work already completed. The projects boast outstanding logistics for future mine development.
