Just 1km east of the Celia shear zone, wide-spaced aircore drilling on the Mustang Shear has defined anomalous gold in saprolite over 2.5km of strike, open to the north and south, with the key mineralised contact still largely untested.
Gateway Mining executive chairman Andrew Bray said: Drilling across the two key shear structures – the Celia Shear and the Mustang Shear – continues to demonstrate widespread gold anomalism. On the Celia structure, MPAC187 intersected 2m @ 3.4gt Au (fresh) in the final two metres of the hole before blade refusal, and 300m to the south, MPAC231 intersected the same structure with 4m @ 2.9g/t Au (fresh) right near the end of the hole.”
Drilling along more than 8km of the known Mustang trend has consistently bracketed the key shear zone between intercepts, prompting Gateway to fast-track tighter infill aircore drilling on multiple lines to pinpoint the contact more accurately ahead of follow-up reverse circulation (RC) drilling.
Gateway says ongoing bottom-of-hole sampling for multiple elements, combined with historic data, is sharpening the geological map, highlighting mafic-intermediate contacts that directly link to high-grade mineralisation identified at the company’s recently acquired Horse Well gold camp.
The Mustang shear’s flexures and structural complexity – especially in the underexplored southern area where it converges with the Celia Shear – appear to have created prime structural traps ripe for hosting large-scale gold systems.
With two rigs mobilising to the project shortly – one infilling and tightening the hole-spacing around stronger anomalism and the other systematically stepping southwards – Gateway is ramping up the hunt. Follow-up RC drilling will zero in on the refined shears once they have been mapped in greater detail.
With the bit between its teeth and $13 million in cash and liquid assets as at the end of the September quarter, plus a post-quarter $22.5 million raise, Gateway is well placed to chase this emerging system in one of WA’s hottest gold belts.
Early positive signs are stacking up strongly, with high grades in fresh rock, open mineralised trends and clear geological and structural ties to proven gold camps, putting the Yandal fringe area firmly on the radar as a potential new Eastern Goldfields play.
