Great Boulder extends Mulga Bill strike extent to 3.7 kilometres

Great Boulder Resources Ltd (ASX:GBR) has identified gold over more than 3.7 kilometres of strike during recent aircore and auger programs at Mulga Bill within the Side Well Gold Project near Meekatharra in Western Australia. A 6,166-metre aircore program confirmed the strike of mineralisation within the Mulga Bill corridor, with multiple parallel north-south mineralised trends now apparent and the strike has been extended by a further 650 metres to the south. New zones of mineralisation have been discovered with best results of 6 metres at 2.04 g/t gold from 81 metres, 4 metres at 2.33 g/t from 44 metres and  7 metres at 1.13 g/t from 80 metres. The company will begin a follow-up drilling program as soon as a rig is available. Exploration “progressing nicely” GBR managing director Andrew Paterson said: “Our exploration program at Side Well is progressing nicely, with these excellent aircore results at Mulga Bill plus the auger anomalies in a new prospect to the east. “We’ve decided to return to Mulga Bill for another round of aircore drilling, with 4,000 metres planned in the next campaign before we commence RC (reverse circulation) drilling. “The auger results east of Mulga Bill highlight gold potential in an area that’s never been explored before and appear to be the northern continuation of structures coming north from the Gabanintha Gold Project. “The Great Boulder technical team believes that this eastern target has significant potential. “We have more auger work planned there, and at the northern end of the project, which is set to commence as soon as possible.” Anomaly at eastern Side Well While aircore drilling was underway the company also completed an auger program over about 6 kilometres of prospective strike on the eastern side of Side Well. The area covered by this program includes one historic shaft identified by GBR’s geologists, as well as a small nugget patch recently worked by local prospectors. Multi-element analysis of the samples has identified a high-tenor gold pathfinder anomaly over an 800-metre area, with arsenic above 90 parts per million (ppm) and antimony above 1ppm. The relatively subdued gold response may reflect the lack of a well-developed pedogenic carbonate horizon at Side Well. This strong response from pathfinder elements, particularly arsenic and antimony, is a positive indicator of gold potential in early-stage exploration geochemistry. Next steps A second round of aircore drilling will focus on Mulga Bill, infilling the prospect to 100 metres line spacing, which will be followed by the next round of deeper RC drilling. A follow-up auger program will be conducted over the arsenic-antimony and gold-silver anomalies, infilling the auger pattern to 200 metres by 50 metres spacing and extending coverage to the south. An initial 400 metres by 50 metres auger grid will also be sampled over the northern end of Side Well, where the Meekatharra-Wydgee greenstone belt is disrupted by a series of small intrusive bodies. This setting is a classic structural target for gold mineralisation.
