THE DRILL SERGEANT: Gateway Mining (ASX: GML) reported results from a recently completed reverse circulation (RC) drilling program around the Whistler gold deposit, within the company’s 100 per cent-owned Gidgee gold project in Western Australia.
Gateway Mining explained the drilling program was designed to undertake a first-pass assessment along strike to the north and south of the Whistler gold deposit to provide understanding of any potential to grow the current Inferred Resource of 1.7 million tonnes at 2.23 grams per tonne gold for 120,000 ounces of contained gold.
The drilling at Whistler was part of a large RC drilling campaign Gateway carried out over several targets at Gidgee, which included both the recent discovery of an extensive zone of shallow oxide gold at Achilles and the expansion of the Montague gold deposit.
The Whistler South zone has been defined in shallow drilling over a strike length of at least 500 metres and remains totally untested at depth.
Results from the latest drilling that continued to define this gold mineralised trend are:
13 metres at 1.6g/t gold from 58m; and
5m at 1g/t gold from 23m.
The company considers the new results from wide-spaced reconnaissance drilling both to the north and south of the Whistler Resource provided further strong evidence of the potential for a large-scale gold system.
“The new results, combined with some significant advances in our geological thinking over the Christmas/New Year period, amount to a really exciting breakthrough at Whistler, demonstrating that it has excellent potential to grow substantially, both to the north and south,” Gateway Mining managing director Peter Langworthy said in the company’s announcement to the Australian Securities Exchange.
“We have confirmed the presence of the new Whistler South mineralised structure over a strike length of 500 metres, and it remains totally untested at depth.
“Meanwhile, to the north of the Whistler Resource we have now located the strike extension of the structure that can now be targeted with the next phase of drilling – more than doubling the overall scale of the system to at least 900 metres.
“In addition to the granodiorite-hosted mineralisation, we are also now delineating and understanding the significance of the multiple mafic-hosted hanging wall lodes.
“We are confident that these will develop into a significant zone of mineralisation that is strongly complementary to the main Whistler Resource.
“It is worth noting that all these positions are in close proximity to the current Whistler optimised pit shell, and any expansion of this would easily incorporate these new areas of mineralisation.
“Looking ahead, we will finalise the reporting of the remaining results from the drilling programs completed in December, including the air-core drilling program that comprised first-pass testing of a number of completely new areas.
“We will then prioritise and plan our next exploration steps, taking into the account the significant advances we have made recently in terms of expanding the potential at Whistler and Montague, defining a significant new zone of shallow oxide mineralisation at Achilles and improving our understanding of a number of other emerging prospects.
“Recent drilling has once again reinforced the very large and prospective nature of the Gidgee gold project.
“Our focus this year will be to find the quickest and most cost-effective way of unlocking substantial new discoveries while at the same time rapidly building our resource inventory from the strong base we have already established.”
