Gateway Mining (ASX:GML) has extended ‘high-grade’ gold mineralisation to 2.5km of continuous strike at its Cowza discovery within the Yandal Gold Project in Western Australia.
The company’s latest aircore drilling returned consistent intercepts across each drill line. ‘Standout’ results include 27m @ 1.4 grams per tonne gold (Au) from 84m in hole CZAC071 and 16m @ 1.9g/t Au from 88m in CZAC069.
CZAC071 returned 3.3g/t Au in the final 1m sample and remained within the shear zone at the bottom of the hole.
Drilling has extended the strike length from the initial 800m discovery announced in June to approximately 2.5km of continuous gold mineralisation along a mafic-intermediate contact zone.
“This 2.5km strike extent sits within a broader 4.5km strongly demagnetised, structurally complex zone,” CEO Richard Pugh says.
“Drilling on the remainder of the strike length has intersected the same consistent shearing, veining and alteration as observed in the gold-mineralised holes received to date.
“It is believed that the same hydrothermal fluids that de-magnetised the rocks are the same fluids that deposited the gold, suggesting that Cowza is shaping up to be a very significant high-grade gold system of substantial scale.”
Mineralisation is structurally controlled along a major regional shear zone at the contact between intermediate and mafic volcanic sequences.
Meanwhile, two key target structures are emerging: the primary shear zone (CZAC071) and a footwall target (CZAC069).
Other results include 16m @ 1.3g/t Au from 68m in CZAC051, 8m @ 2.2g/t Au from 76m in CZAC070, and 5m @ 2.8g/t gold from 148m in CZAC066.
Drilling for another 2km to the north continues to intersect similar shearing, veining and alteration, with assays pending. A second reverse circulation rig arrives on site this weekend.
