International Goldfields hits new mineralisation and extends Brazilian strike
THE DRILL SERGEANT: International Goldfields (ASX:IGS) has completed an RC drilling program on the Ana prospect, located within the Latin gold project (IGS 93 per cent) in Mato Grosso, Brazil.
The company has received results for an additional 12 RC holes, which it said has confirmed gold mineralisation for 1,000 metres.

IGS said the mineralisation is centred on a 300m long high grade shoot defined in earlier diamond drilling that intersected 21m at 5.9 grams per tonne gold, including 8m at 13.6g/t gold, and 18m at 3.24g/t gold.
Better intercepts in the recent four-metre composite sampling results include:
– 12 metres at 1.11 grams per tonne gold from surface on a 200 metres west step-out on the PF quartz vein zone;
– 12m at 1.10g/t gold from 44m, including 4m at 2.06g/t gold located 650m east along trend of PF vein zone mineralisation.; and
– 4m at 2.41g/t gold and 4m at 2.17g/t gold located on new sub-parallel mineralised zone.
IGS has now received assays on the first 3,137m of drilling of the 4,779m drill campaign that has tested six target areas within the 2.5 kilometres by 4 kilometres surface gold anomaly.
IGS has also completed seven diamond drill holes with all holes intersecting quartz veining and sulphide, which it claims to be visually analogous to previous mineralised diamond intercepts.
“Four of the potentially mineralised intercepts target down-dip extensions of the PF Quartz Vein zone,” International Goldfields said in its ASX announcement.
“The four holes test the extents of the 300 metres long high grade shoot interpreted from drilling results received to date.
“The deeper diamond drilling indicates strong potential for a steep east plunge to the high grade zone to extend at depth, with the easternmost hole intersecting a 24 metre wide interval from 138.2 metres depth containing both pyrite and chalcopyrite sulphides within the interval, and abundant quartz veining and quartz-healed breccia textures within the broader zone of sheared granites and dolerite dyke rocks.”
IGS said an additional three holes have intersected sulphides and quartz veining on further extension drilling along strike to the west, which the company considers has the potential to further extend the mineralised trend beyond the one kilometre extent it has been able to confirm with RC drilling results it has received to date.
