PC Gold (ASX:PC2) has identified two new zones of mineralisation at the Spring Hill Gold Project in the Northern Territory, from extensional drilling conducted to the south of the existing resource estimate boundary.
Outside of resource drilling on the Hong Kong and Macau lodes, the company says the first hole returned a wide zone of gold, returning an interval of 14.9m @ 3.84 grams per tonne gold from 143.1m, including 0.98m @ 30.6g/t gold from 147.9m at drillhole SDH25-026.
PC Gold returned visible gold 40m along strike and down plunge of this drill hole, extending the Main Zone strike by 80m south, beyond the 400m strike length determined in the resource estimate.
The company has completed seven holes of the greater 18-hole southern extension drilling program, with drilling ongoing and one diamond rig at the target.
Resource definition holes at the Macau and Hong Kong zones have been dispatched for assaying, with results expected in early Q2 2026.
Executive Chairman Ashley Pattison says extending the Main Zone has “important implications for the overall scale of mineralisation at Spring Hill”.
“It reinforces our view that this is a growing system within what is already the highest-grade area of the resource,” Pattison says.
“Importantly, this intercept sits within our existing pit optimisation shell and was previously modelled as waste due to a lack of drilling. From a mining perspective, bringing additional mineralisation into the current pit shell has the potential to directly enhance open pit inventory and project economics.
“Our work indicates the Main Zone may extend up to a further 500 metres to the south, broadly parallel to the Hong Kong Lode.
“The proximity of these two lodes presents a compelling opportunity for increasing the scale of operations and improving mining efficiencies over time.”
