White Cliff Minerals (ASX:WCN) has added another discovery to its Rae Copper Project, with first-ever drilling at Bornite Hills intersecting broad bornite-dominant mineralisation beneath an historic ultra-high-grade surface occurrence.
The market liked what it saw. White Cliff shares were up around 17 on strong trading volume this morning as investors reacted to a new copper zone sitting just 32km from Danvers.
Over 32 metres of bornite
The standout hole, BNH26003, intersected over 32m of bornite-dominant mineralisation, including intervals of semi-massive bornite.
A second hole, BNH26001A, returned 13.7m of bornite-chalcopyrite mineralisation in veins and breccias.
Importantly, the drilling has now confirmed mineralisation more than 60m vertically below surface.
That is the first real evidence that Bornite Hills has meaningful depth continuity.

Below 46.99% copper at surface
Bornite Hills was already interesting before the drill arrived.
Historic trenching returned 3.66m @ 46.99% Cu at surface.
Now White Cliff has shown that bornite mineralisation continues underneath that occurrence.
The system sits along a fault structure interpreted to branch from the Herb Dixon Fault Zone and remains largely untested across around 725m of prospective strike.
That leaves plenty of room for follow-up.

Rae keeps adding targets
Bornite Hills is not an isolated story.
The discovery sits within the broader Rae Copper Project, where White Cliff is already drilling Danvers and testing a much larger sediment-hosted copper system.
Recent drilling has also confirmed copper mineralisation across a footprint greater than 10km² along the base of the Rae Group.
That gives White Cliff more than one style of copper target and more than one place to keep the rigs busy.

Geophysics takes over next
The company has commissioned a high-definition magnetic, gravity and radiometric survey covering over 70km of prospective contact.
The aim is to map the structures, basement architecture and potential fluid pathways that may have controlled mineralisation.
That data will be used alongside drilling to rank targets for 2027.
What comes next
The near-term catalyst is assays.
Results from Bornite Hills are expected in October, giving White Cliff its first proper look at grade across the broad intervals already seen visually.
Two diamond rigs also remain active at Danvers, while regional geophysics continues across Rae.
Bornite Hills has now delivered the width, the next question is whether the assays deliver the grade.
