Antimony Veins in Whroo Gold Mines
HIGHLIGHTS
» Ahead of planning a drilling program for the 100%-owned Whroo Project, Nagambie’s consultant geologist researched the publicly available information on the Geological Survey of Victoria website. The GSV 1877 Report on the Whroo Mines (G47156_progress-rep_5.pdf) file via link:
https://gsv.vic.gov.au/SearchAssistant2/details?q=internal_id:47156 indicates that the antimony veins at Whroo are an analogue to the antimony veins recently discovered by the Company under the West Pit at the Nagambie Mine.
» “The auriferous reefs at Whroo, in general terms, may be said to differ but little from those at Rushworth. The only noticeable exceptions are the Balaclava Hill veins, the Albert Reef, and the Stockyard Reef [and its associated Peep-o’-Day Reef]. In each of these lodes the occurrence of antimony veins, or the association of antimony ores in the auriferous veins, is a marked feature.” (from page 165 of GSV 1877 Report on Whroo Mines)
» “The antimony vein which intersects the Albert Reef in the U. and F. Antimony Company’s mine, at Whroo, strikes in a north and south direction [strikes N-S] and dips slightly to the west [dips W].” (from page 173 of GSV 1877 Report on Whroo Mines)
» “It [antimony] is found as a sulphide [silvery-coloured stibnite Sb₂S₃] and yellow oxide in paying quantities at Whroo ……. The only vein now being worked is that intersecting the Albert Reef, Whroo. It occurs in connection with a gold-bearing quartz vein. The quartz is ‘cobbed off’ and crushed, and the antimony ore either shipped to England or sold in Melbourne [‘direct shipping ore’ or ‘DSO’ in today’s parlance].
» On 18 February 2022, Nagambie announced to the ASX the assay results for two diamond holes drilled by a then-joint venturer under the Balaclava Mine. The best gold assays were 49.7 g/t Au, 16.5 g/t Au and 8.4 g/t Au in hole MDDBC001. The best antimony assays were 16.5% Sb, 10.5% Sb and 6.3% Sb in hole MDDBC001.
