Silver City Minerals has intersected highly encouraging, high grade base-metal and silver in massive sulphide mineralization at the multi-commodity Allendale project in the far west of New South Wales.
The company considers this to be an excellent result from its first-pass, shallow drilling program with assays received from 20 drill holes. This drilling and historic diamond drill holes indicate mineralization extends over a strike length of at least 300 metres and to depths of 200 metres.
Best results are: 10 metres from 15 metres @ 16.1% lead plus zinc and 29.0 grams/tonne silver including 1 metre from 15 metres @ 38.3% lead plus zinc and 80.1 grams/tonne silver, and 2 metres from 18 metres at 33.8% lead plus zinc and 43.3 grams/tonne silver; 7 metres from 33 @ 4.8% lead plus zinc and 21 grams/tonne silver; 2 metres from 47 metres @ 19.9% lead plus zinc and 39.2 grams/tonne silver; 9 metres from 111 metres @ 5.6% lead plus zinc and 19.7 grams/tonne silver, including 2 metres from 117 metres @ 13.8% lead plus zinc and 51.2 grams/tonne silver; and 2 metres from 53 metres @ 11.8% lead plus zinc and 44.3 grams/tonne silver.
Silver City's managing director Chris Torrey says, “It is excellent to see such encouraging high grade results so close to the surface in our first-pass drilling program at Allendale. To my knowledge these base metal-rich intersections are the most significant published from Broken Hill-type mineralization in the district outside the Broken Hill ‘Line of Lode’ since the announcement of the Stephens Trig drill data in 2004.
“While we are still waiting for completed assays, these results, along with indications from our visual logging and portable XRF analyses, suggest the presence of a number of well mineralized horizons.
“A significant portion of the mineralization sits on the margin of a distinctive amphibolite rock which has been mapped extensively in the area, providing an excellent target for future exploration. Geological and structural modelling of this unit has commenced and will greatly assist in targeting holes for the next, important round of drilling that has the potential to locate near-surface, high grade base-metal and silver resources.”
Silver City has completed 21 reverse circulation drill holes close to the old Allendale mine for a total of 1829 metres. The purpose of the program was to test mineralization down to a level of about 100 metres below surface.
