Drilling by Gateway Mining (ASX: GML) at its Yandal gold project in Western Australia has confirmed southerly plunging, primary high-grade mineralisation highlighting the potential for multiple mineralised pods along the Celia South structure.
A recent reverse circulation campaign was designed to follow-up earlier shallow aircore intersections of 10 metres at 2.2 grams per tonne gold from 66m and 16m at 1g/t gold from 104m, as well as to better understand the geometry of mineralisation beneath the zone of weathering.
The work confirmed the presence of a coherent south-plunging gold shoot extending from the near-surface aircore mineralisation into fresh rock and delivered best reverse circulation intercepts of 11m at 4.5g/t gold from 89m and 22m at 1.1g/t gold from 94m including 4m at 3.7g/t.
The strongest mineralisation has now been traced across several drill sections and displays a consistent southerly plunge, with the shoot remaining open down plunge and along strike.
Importantly, current drilling has only tested the upper portion of the emerging gold system, leaving significant scope for further extensions.
South-Plunging Gold System
Chief executive officer Richard Pugh said the latest drilling results represented a step forward in the company’s understanding of the Celia South system.
“What initially began as isolated shallow high-grade aircore intercepts has now evolved into a clearly defined south-plunging gold system that remains open at depth and along strike,” he said.
“We believe that these results are not confined to a single occurrence but instead represent a series of multiple mineralised pods developing along the broader Celia South shear corridor, which is exactly the type of architecture observed in many significant Yandal gold deposits.”
“Our recent reverse circulation program successfully mapped the geometry of one of these shoots, while our geological modelling now suggests additional mineralised centres may occur north and south of the current drilling area and our aircore rigs are moving to systematically test these targets.”
Celia South and Cowza Drilling
Gateway’s drilling in August defined gold mineralisation at Celia South over more than 1.5 kilometres of strike, highlighting the emergence of multiple mineralised centres along the broader structural trend.
Those results supported the interpretation that the Celia Shear Corridor hosts a large-scale hydrothermal gold system, where mineralisation is associated with favourable lithological contacts, extensive shearing, quartz veining, and alteration.
Meanwhile, the company has completed the first diamond hole at the recently identified Cowza structure delineated over a strike length of 4.5km by extensive aircore work that defined continuous oxide gold mineralisation, remaining open to the north and south.
Diamond drilling is expected to provide critical information on geological controls, structural architecture, and the orientation of high-grade gold shoots in support of future resource definition and exploration programs.
