Silver Mines Ltd (ASX:SVL) says a recently-completed 2D seismic reflection survey has clearly defined the Bowdens silver deposit and its potential system extensions near Mudgee in New South Wales.
The survey, which consisted of 12.44 line-kilometres, was aimed at determining the seismic response of the Bowdens Deposit and to identify potential extensions to the system both down plunge and dip at depth, as well as to highlight possible “analogue” responses within prospective areas such as Prices Gully.

Mineralisation within the proposed open pit shows as anomalously high amplitude and flat lying reflectors, while deeper high-grade silver mineralisation, such as the Northwest and Aegean Zones, have lower ‘dull’ amplitudes with chaotic and discontinuous features.
The survey also generated significant new drill targets along Prices Gully, situated about 900 metres to the east of the Bowdens Deposit.
Silver Mines now hopes to complete a drilling program of 3,000 metres testing priority targets in the immediate vicinity to the Bowdens Silver Deposit.
A major caldera ring fault was also identified through the survey, which can potentially become the major conduit for hydrothermal fluids to the Bowdens System.

The seismic survey is a key component of the company’s research and development program, which will integrate all data and accelerate ore discovery through predictive modelling.
