The Nanadie discovery is open in every direction.
Solstice's Nanadie Copper-Gold Project, roughly 100km south-east of Meekatharra in WA's
Murchison district, is currently traced along 1.2km of strike with a mineralised host gabbro
100-200 metres wide. Recent deep diamond drilling shows the system remains wide open at
depth, while RC drilling is extending it further north and south, giving Solstice multiple
avenues for near-term resource growth.
Deep drilling is confirming scale, not just a surface story.
A 629-metre hole returned multiple long runs of over 1% copper, and a follow-up hole drilled
to roughly 800 metres hit similar high-grade material in the same host rock before running
out of drill rods. Castleden points to these paired deep intercepts as evidence of a genuinely
large volume of mineralised rock, with potential for a second, underground stage of the
deposit beneath the open pit.
The resource is expected to grow materially from its starting point.
Solstice acquired an existing Inferred Mineral Resource of roughly 40 million tonnes,
compiled from several previous owners' drilling with no clearly defined margins. Castleden
says the company's own drilling has already shown the deposit extends well beyond that
footprint in every direction, and expects the next resource update to be materially larger than
A strong balance sheet is funding an aggressive, dilution-free drill campaign.
With around $45 million in cash and no debt, Solstice can keep multiple rigs turning without
needing to raise capital in the near term. The stock now has three broker analysts covering
it, and six analysts are visiting the site the following week, reflecting growing institutional
interest in a rare tier-one scale copper discovery in Western Australia.
Solstice remains firmly in exploration mode, with a separate gold asset as a bonus.
The board and management, all geologists with meaningful equity in the company, are
focused squarely on drilling out Nanadie rather than mine planning at this stage, with early
metallurgical, water and flora-fauna studies just getting underway. Solstice also holds a
separate gold package near Cue that it has flagged publicly it may look to monetise or spin
